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.
