Before the activity, our teacher told us some specific arrangements about the activity which theme was “Labor is the most glorious thing”. Meanwhile, he stressed on the importance and value of working by our own hand. When I got home, I packed up for trip excitedly. On the farm, we helped picking watermelons and carried them to the truck. While worked, I realized how tougher it was to work in the fields in the burning sun. When I came back home, I shared your experience with my parents during dinner. Happy and proud ,they spoke high of my behavior.

TOEFL is the most widely used language assessment exam for American universities. There are two major versions of the TOEFL test. The first is the iBT, or Internet-based Test. It is offered in most of the world and accepted by nearly every university and scholarship program in the United States. The other is called the Paper-based Test or PBT.1. Here are some tips for getting started with TOERL: Plan ahead —2.Do not expect a big lift in your test results in two weeks. There is no easy way to improve your score quickly. You will have to spend a lot of time and energy. Master the basics first —3..If you score below 500 on the PBT or 70 on the iBT, study the fundamentals for a few months and come back to the TOEFL later. Get a study guide It is easy to find study guides for the iBT. 4. The best study guides will have explanations in the answer key. PBT study guides are difficult to find because the test is being phased out. 5.— Remember, you are learning a language, not a test. You can improve your TOEFL part of your daily life. Some simple ways are listening to podcasts, watching movies, reading newspapers, sending and reading text messages in English, and writing online comments in English. A.Know English well. B.Use various resources. C.It is still used in some developing countries. D.Raising your score will take months of intensive work. E.If you have a choice, take the iBT if it is not too pricey. F.Pearson, Barron’s,ETS, and Kaplan all produce quality materials. G.You should have at least an upper- intermediate English level before you attempt the test.
An increasing part of the world is becoming artificially lit. Artificial light is often seen as a sign of progress: the march of civilization shines a light in the dark; it takes back the night. But some scientists argue that unnaturally bright nights are bad not just for astronomers but also for nocturnal (夜间的) animals and even for human health. Now research shows the night is getting even brighter. From 2012 to 2016 the earth’s artificially lit area expanded by about 2.2 percent a year, according to a study published last November in Science Advances. However, the measurement does not include light from most of the energy–efficient LED lamps that have been replacing sodium-vapor (钠气灯) technology in cities all over the world ,says Christopher Kyba, a postdoctoral researcher at the German Research Center for Geosciences in Potsdam. The new data came from a NASA satellite instrument called the Visible Infrared Imaging Radiometer Suite (VIRS). It can measure long wavelengths of light, such as those produced by traditional yellow-and-orange sodium-vapor street lamps. But VIIRS cannot see the short-wavelength blue light produced by white LEDs. This light has been shown to disturb human sleep cycles and nocturnal animals’ behavior. The team believes the ongoing switch to LEDs caused already bright countries such as Italy, the Netherlands, Spain and the U.S. to register as having stable levels of lighting in the VIIRS data. In contrast, most nations in South America, Africa and Asia brightened, suggesting increases in the use of traditional lighting. In 2016, a study showed that one third of the world’s population currently lives under skies too bright to see the Milky Way at night. Between 2012 and 2016 the median nation pumped out 15 percent more long-wavelength light as its GDP increased by 13 percent. Overall, counties' total light production correlated with their GDP. 1.Which of the following can best describe artificial light? A.Convenient but unnatural. B.Useful but energy-consuming. C.Progressive but uncomfortable. D.Civilized but harmful. 2.What can we know about the already bright countries? A.Traditional lighting is not used in those countries. B.LED lights are increasingly used in those countries. C.Efforts to reduce harmful light work in those countries. D.People do enjoy stable lighting in those countries. 3.Why does the author mention “the median nation” in the last paragraph? A.To show artificial light has an association with GDP. B.To demonstrate GDP plays an important part in the median nation. C.To stress the median nation was to blame for the light problem. D.To suggest artificial light should be banned in the future. 4.Where is the passage most probably taken from? A.A biology textbook. B.A book review. C.A science magazine. D.A science fiction.
I. M. Pei, one of the best-known architects of the 20th century, has died. He was 102. Born in China, Ieoh Ming Pei moved to the United States in 1935 to study architecture at the Massachusetts Institute of Technology and Harvard University. Pei’s works around the world include museums, government buildings, hotels, schools and other structures built with stone, steel and glass. One of his best-known and most disputed works was built 30 years ago. Pei created a new entrance for the world-famous Louvre Museum in Paris. Pei first spent four months studying the museum and French history. He then drew plans for a 21-meter-tall steel and glass id, with three smaller pyramids nearby. It was a very futuristic style of work for the 12th-century building. A French newspaper criticized Pei’s pyramids as “an annex to Disneyland”. An environmental group said they belonged in a desert. Others accused Pei of ruining one of the world’s greatest landmarks. Pei said the Louvre was the most difficult job of his career. He argued that he had wanted to create a modern space that would not take away from the traditional part of the museum. He said the glass pyramids were based on the works of French landscape architect Le Notre. They honored French history. The pyramids opened in the spring of 1989. Over the years that followed, the structure came to be loved by most, if not all, of its critics. Other well-known Pei buildings include the John F. Kennedy Library in Dorchester, Massachusetts, the National Center for Atmospheric Research in Boulder, Colorado, the East Wing of the National Gallery of Art in Washington and the Dallas City Hall in Texas. Pei officially retired in 1990. However, he continued to work on projects—including museums in Luxembourg, Qatar and his ancestral home of Suzhou. 1.What is true about the entrance created by Pei for the Louvre Museum? A.Pei spent four mouths drawing plans for it. B.There are four pyramids in total. C.It’s in a style of the 12th century. D.It took 30 years to complete the work. 2.What can we infer from Pei’s words in Paragraph 4? A.The glass pyramids were originally designed by Le Notre. B.The glass pyramids were based on the French landscape. C.The glass pyramids were in harmony with the Louvre. D.The glass pyramids reflected both French and Chinese style. 3.What were most people’s attitudes towards Pei’s pyramids years after its opening? A.Indifferent. B.Puzzled. C.Critical. D.Favorable. 4.What do we know about Pei according to the passage? A.He was hardworking, optimistic and easygoing. B.He spread Chinese traditional architecture to the world. C.He created many great works both in China and other countries. D.He was the most outstanding architect of the 20th century.
I've handled chopsticks skillfully for decades. While it used to amuse me, it mildly annoys me now that Chinese react with astonishment to see a foreigner handle them—as if someone from a country that put a man on the moon would somehow be incapable of handing two simple sticks. As you can see, China’s influence stretched far and wide long before opening-up in the late 1970s or today’s Belt and Road Initiative. So the idea that most foreigners cannot use chopsticks is, simply put, fiddlesticks. My first exposure to chopsticks came way back in the 1960s via the elementary piano tune known as Chopsticks, which aroused my curiosity as to what the word meant. Not long afterward, my parents introduced me to Chinese food at King Fong Cafe in Omaha, Nebraska, which, I only learned recently, was among the landmarks of the heartland city’s once-thriving Chinatown in the early 1900s. In fact, I have undergone special kuaizi training (improving skills, for example, by constantly picking up peanuts when I lived with my Chinese tai chi master) and experimentation (exploring the use of chopsticks to snap up popcorn and donuts; I’m working on ice cream). But there’s one western food for which chopsticks are truly a godsend: salads. After moving to China in 2014, I bought a salad at a convenience store, and the clerk handed me kuaizi. I refused at first, but then thought, “All right” and gave it a try. Amazingly useful! I could pick and choose each small piece much more carefully, without having to move awkwardly trying to spear (刺) the crispy carrot or cherry tomato and then move it mouth ward. Another clear advantage of these simplest of tools is that they regulate the pace and volume of eating. It's much harder to “pig out” by shoveling food with chopsticks than with a fork and spoon. However, in the spirit of globalization, let’s not overlook the finer points of knife and fork. In fact, a handy thing about the fork is that everyone can basically use it with each hand. I dare to say that, for Chinese and foreigners alike, switching hands while using chopsticks is not so readily done with confidence. 1.What makes the author feel unhappy about using chopsticks? A.The comments on chopsticks from foreigners. B.Incapacity to handle two simple sticks. C.The idea that foreigners don't like chopsticks. D.Reaction of Chinese on seeing him using chopsticks. 2.What does the underlined word “fiddlesticks” in Paragraph 1 mean? A.nonsense B.reasonable C.acceptable D.shameful 3.What is the advantage of chopsticks according to the passage? A.They can let people wolf down food easily. B.They can spear the crispy carrot or cherry tomato. C.They can be amazingly useful to eat western food. D.They can help users control the pace and volume of eating. 4.What is the best title for the passage? A.Me and Chopsticks B.Chinese Kitchen Culture C.The Globalization of Chopsticks D.Two Sides of Chopsticks

Music makes you more creative.1., they come up with more creative solutions, according to researchers. It may be because music improves your brain’s flexibility. Another reason may be that it relaxes you enough for the creative juices to flow. But don’t play music too loudly. Music can help during surgery. 2.. After surgery, it helps reduce pain. An analysis of 73 studies confirmed that listening to music before, during or after surgery reduces anxiety and pain levels, which in turn means less pain medication. 3. Studies have found that when you’re running, biking or walking, you’ll go farther with music on. Music relieves your discomfort and motivates you to stay on. The effect is so obviously great that the author of a review examining the psychological effects of music on exercise called music “a type of legal performance-improvement drug”. Music aids sleep. Listening to music before bed can help you fall asleep faster and wake up less often during the night. 4.. In one study, seniors with sleep problems who listened to 45 minutes of soft slow music before bed reported a 35 percent improvement in their sleep. Music gets you to ignore the passing of time. Scientists have shown repeatedly that people judge a period of waiting shorter when music is playing. Businessmen use that to their advantage, playing music so you stay longer and spend more. For instance, more drinks and food are sold in bars and restaurants when music is played. 5., grocery sales increase by 38 percent. A.In this case, you’ll feel more relaxed in the morning B.And if the background music is slow C.Then you play a piece of brief music D.When people listen to happy music than when they sit in silence E.When music is played varying from a tune to another F.Music makes you get rid of the idea of quitting a workout G.Listening to music before surgery has been shown to ease anxiety
Humans really do have a sixth sense that lets us detect magnetic fields (磁场), but we’re not aware we have it. It has long been known as ESP, Spider Sense, or the ability to see things before they happen. But now scientists have proved that humans really do have a sixth sense-that lets them detect magnetic fields. Tests have shown that mankind may have the same inborn sense of Earth’s magnetic field that has long been proved to exist in animals. By putting a protein from the human retina (视网膜) into fruit flies, researchers noticed that the insect adjusted its flight path just as if its eye had not been changed. This suggests that the “sixth sense” does exist in humans but we might not be aware of it. Animals use such sight to navigate long distances during migration or, in the case of birds, to “see” where they are going. The complex tests involved examining the process by which light goes through a bird’s eye, which has interested the scientific community for more than 30 years. In the late 1970s, the physicist Klaus Schulten concluded that birds fly by relying on geomagnetically (地磁) sensitive biochemical reactions in their eyes. Tests have shown that the special cells in the eye carry out this function using the protein cryptochrome (蛋白隐色素). Professor Reppert’s team used wild fruit flies, replacing their version of cryptochrome with the human equivalent (等价物), and then put them in a maze (迷宫) with each wing wrapped in a metal coil (金属圈). They then sent electricity through it so that the coil was magnetised in a way which is just like Earth’s electromagnetic field (电磁场). The flies responded in exactly the same way as if they had their own cryptochrome, by either avoiding the magnetic fields or moving towards them if the researchers had placed sugar nearby. The new study was published in the journal Nature Communications. 1.What do we know about humans’ sixth sense? A.Humans have been aware of it since ancient times. B.It is quite different from the animals’. C.It is the ability to predict what will happen. D.It is also a sense developed after birth. 2.Why did researchers put a protein from the human retina into fruit flies? A.To change fruit flies’ flight path. B.To test if humans have a sixth sense. C.To examine the process of birds’ flying. D.To allow researchers detect magnetic fields. 3.What does the underlined word “it” in Paragraph 3 refer to? A.the maze B.each wing C.cryptochrome D.the metal coil 4.After being replaced the cryptochrome, how are the wild fruit flies? A.They responded normally as if there had been nothing changed. B.They couldn’t avoid the magnetic fields like before. C.They lost the sense of direction completely. D.They couldn’t find the sugar the researchers had placed nearby.
Professor Ashok Goel of Georgia Tech developed an artificially intelligent teaching assistant to help handle the enormous number of student questions in the online class, Knowledge-Based Artificial Intelligence. Professor Goel already had eight teaching assistants, but that wasn’t enough to deal with the overwhelming number of daily questions from students. Many students drop out of online courses because of the lack of teaching support. When students feel ignored or confused and reach out with questions that go unanswered, their motivation to continue begins to taper off. Professor Goel decided to do something to improve this situation and his solution was to create a virtual assistant named Jill Watson. Goel and his team developed several versions of Jill Watson before releasing her to the online forums. At first, the virtual assistant wasn’t too great. But Goel and his team sourced the online discussion forum to find all the 40,000 questions that had ever been asked since the class was launched. Then they began to feed Jill with the questions and answers. After some adjustments and sufficient time, Jill was able to answer the students’ questions correctly 97% of the time. The virtual assistant became so advanced and realistic that the students didn’t know she was a computer. The students, who were studying artificial intelligence, were interacting with the virtual assistant and couldn’t tell it apart from a real human being. Goel didn’t inform them about Jill’s true identity until April 26. The students were actually very positive about the experience. The goal of Professor Goel’s virtual assistant next year is to take over answering 40% of all the questions posed by students on the online forum. Professor Goel has a much rosier outlook on the future of artificial intelligence. 1.What problem did Professor Goel meet with? A.Students’ questions were too many to deal with. B.Teaching assistants were not professional at all. C.Many students were lack of interest in his class. D.He felt confused about how to teach online. 2.Which of the following best explains the underlined phrase in Paragraph 2? A.grow dramatically B.increase sharply C.decrease gradually D.decline unreasonably 3.What do we learn about Jill Watson? A.She could answer all questions without mistakes. B.She turned out to be a great success. C.Her performance was remarkable all the way. D.Her true identity was still a secret to students. 4.What’s the main idea of the text? A.A robot gives an online course. B.Virtual assistant is getting popular in school. C.Robots will replace humans in online classes. D.One Georgia Tech’s teaching assistant isn’t human.
Nicole Ihus’s son John Henry was born last month with a life-threatening disease. Nicole and her husband, who live in Kansas City, contacted doctors from Minnesota and Missouri in hopes of finding a doctor who could treat John Henry for the condition, but to no avail. Luckily, Nicole managed to get in contact with the “best doctor in the world for this condition” at Johns Hopkins All Children’s in St. Petersburg, Florida, so she traveled all the way to the Sunshine State to give her newborn son a fighting chance. After John Henry was into the ICU, Nicole felt alone in the new state, although she knew that she had to leave her son’s side in order to buy him some new clothes. Upon ordering an Uber ride to the nearby Rhea Lana children’s clothing store, she was picked up by a woman named Belinda. Shortly after Nicole got into Belinda’s car, the new mother couldn’t help talking about her heartbreaking circumstances. “She told me her story,” Belinda said. “She was in tears a couple of times and I really felt for her.” Rather than simply dropping Nicole off at the store, however, Belinda parked the car and insisted on accompanying her passenger into the store so she could treat John Henry to new clothes. Needless to say, Nicole was filled with gratitude. Nicole said, “For this stranger to go completely out of her way - stop what she was doing and stop making money- to come be with me for a couple of hours while we shopped together, that was just incredible.” As Nicole cares for her newborn son and raises money for his medical conditions, she hopes to introduce the Uber driver to her son as a thank you for her compassionate gesture. 1.Why did the new mother have to travel to Florida?

Music makes you more creative.1., they come up with more creative solutions, according to researchers. It may be because music improves your brain’s flexibility. Another reason may be that it relaxes you enough for the creative juices to flow. But don’t play music too loudly. Music can help during surgery. 2.. After surgery, it helps reduce pain. An analysis of 73 studies confirmed that listening to music before, during or after surgery reduces anxiety and pain levels, which in turn means less pain medication. 3. Studies have found that when you’re running, biking or walking, you’ll go farther with music on. Music relieves your discomfort and motivates you to stay on. The effect is so obviously great that the author of a review examining the psychological effects of music on exercise called music “a type of legal performance-improvement drug”. Music aids sleep. Listening to music before bed can help you fall asleep faster and wake up less often during the night. 4.. In one study, seniors with sleep problems who listened to 45 minutes of soft slow music before bed reported a 35 percent improvement in their sleep. Music gets you to ignore the passing of time. Scientists have shown repeatedly that people judge a period of waiting shorter when music is playing. Businessmen use that to their advantage, playing music so you stay longer and spend more. For instance, more drinks and food are sold in bars and restaurants when music is played. 5., grocery sales increase by 38 percent. A.In this case, you’ll feel more relaxed in the morning B.And if the background music is slow C.Then you play a piece of brief music D.When people listen to happy music than when they sit in silence E.When music is played varying from a tune to another F.Music makes you get rid of the idea of quitting a workout G.Listening to music before surgery has been shown to ease anxiety
Humans really do have a sixth sense that lets us detect magnetic fields (磁场), but we’re not aware we have it. It has long been known as ESP, Spider Sense, or the ability to see things before they happen. But now scientists have proved that humans really do have a sixth sense-that lets them detect magnetic fields. Tests have shown that mankind may have the same inborn sense of Earth’s magnetic field that has long been proved to exist in animals. By putting a protein from the human retina (视网膜) into fruit flies, researchers noticed that the insect adjusted its flight path just as if its eye had not been changed. This suggests that the “sixth sense” does exist in humans but we might not be aware of it. Animals use such sight to navigate long distances during migration or, in the case of birds, to “see” where they are going. The complex tests involved examining the process by which light goes through a bird’s eye, which has interested the scientific community for more than 30 years. In the late 1970s, the physicist Klaus Schulten concluded that birds fly by relying on geomagnetically (地磁) sensitive biochemical reactions in their eyes. Tests have shown that the special cells in the eye carry out this function using the protein cryptochrome (蛋白隐色素). Professor Reppert’s team used wild fruit flies, replacing their version of cryptochrome with the human equivalent (等价物), and then put them in a maze (迷宫) with each wing wrapped in a metal coil (金属圈). They then sent electricity through it so that the coil was magnetised in a way which is just like Earth’s electromagnetic field (电磁场). The flies responded in exactly the same way as if they had their own cryptochrome, by either avoiding the magnetic fields or moving towards them if the researchers had placed sugar nearby. The new study was published in the journal Nature Communications. 1.What do we know about humans’ sixth sense? A.Humans have been aware of it since ancient times. B.It is quite different from the animals’. C.It is the ability to predict what will happen. D.It is also a sense developed after birth. 2.Why did researchers put a protein from the human retina into fruit flies? A.To change fruit flies’ flight path. B.To test if humans have a sixth sense. C.To examine the process of birds’ flying. D.To allow researchers detect magnetic fields. 3.What does the underlined word “it” in Paragraph 3 refer to? A.the maze B.each wing C.cryptochrome D.the metal coil 4.After being replaced the cryptochrome, how are the wild fruit flies? A.They responded normally as if there had been nothing changed. B.They couldn’t avoid the magnetic fields like before. C.They lost the sense of direction completely. D.They couldn’t find the sugar the researchers had placed nearby.
Professor Ashok Goel of Georgia Tech developed an artificially intelligent teaching assistant to help handle the enormous number of student questions in the online class, Knowledge-Based Artificial Intelligence. Professor Goel already had eight teaching assistants, but that wasn’t enough to deal with the overwhelming number of daily questions from students. Many students drop out of online courses because of the lack of teaching support. When students feel ignored or confused and reach out with questions that go unanswered, their motivation to continue begins to taper off. Professor Goel decided to do something to improve this situation and his solution was to create a virtual assistant named Jill Watson. Goel and his team developed several versions of Jill Watson before releasing her to the online forums. At first, the virtual assistant wasn’t too great. But Goel and his team sourced the online discussion forum to find all the 40,000 questions that had ever been asked since the class was launched. Then they began to feed Jill with the questions and answers. After some adjustments and sufficient time, Jill was able to answer the students’ questions correctly 97% of the time. The virtual assistant became so advanced and realistic that the students didn’t know she was a computer. The students, who were studying artificial intelligence, were interacting with the virtual assistant and couldn’t tell it apart from a real human being. Goel didn’t inform them about Jill’s true identity until April 26. The students were actually very positive about the experience. The goal of Professor Goel’s virtual assistant next year is to take over answering 40% of all the questions posed by students on the online forum. Professor Goel has a much rosier outlook on the future of artificial intelligence. 1.What problem did Professor Goel meet with? A.Students’ questions were too many to deal with. B.Teaching assistants were not professional at all. C.Many students were lack of interest in his class. D.He felt confused about how to teach online. 2.Which of the following best explains the underlined phrase in Paragraph 2? A.grow dramatically B.increase sharply C.decrease gradually D.decline unreasonably 3.What do we learn about Jill Watson? A.She could answer all questions without mistakes. B.She turned out to be a great success. C.Her performance was remarkable all the way. D.Her true identity was still a secret to students. 4.What’s the main idea of the text? A.A robot gives an online course. B.Virtual assistant is getting popular in school. C.Robots will replace humans in online classes. D.One Georgia Tech’s teaching assistant isn’t human.
Nicole Ihus’s son John Henry was born last month with a life-threatening disease. Nicole and her husband, who live in Kansas City, contacted doctors from Minnesota and Missouri in hopes of finding a doctor who could treat John Henry for the condition, but to no avail. Luckily, Nicole managed to get in contact with the “best doctor in the world for this condition” at Johns Hopkins All Children’s in St. Petersburg, Florida, so she traveled all the way to the Sunshine State to give her newborn son a fighting chance. After John Henry was into the ICU, Nicole felt alone in the new state, although she knew that she had to leave her son’s side in order to buy him some new clothes.
