How to Remember What You Read Reading is important, but the next important step is making sure that you remember what you've read! 1.You may have just read the text, but the ideas, concepts and images may fly right out of your head. Here are a few tips for remembering what you read. Are you confused? If the plot, characters, or word usage is confusing for you, you likely won't be able to remember what you read. 2. If you don't understand what you're reading, how would you remember it? There are a few things you can do--use a dictionary ； look up the difficult words； consult a teacher... Are you connected? Does a character remind you of a friend? Does the setting make you want to visit the place? Does the book inspire you and make you want to read more? With some books, you may feel a connection right away. 3.How willing are you to make the connections happen? Read it; hear it; be it! Read the lines. Then, speak them out loud. And, put some character into the words. When he was writing his novels, Charles Dickens would act out the parts of the characters. He'd make faces in the mirror and change his voice for each character. 4. . How often do you read? If you read frequently, you'll likely have an easier time with remembering what you're reading and what you've read. 5.As you make reading a regular part of your life, you'll make more connections, stay more focused and understand the text better. You'll learn to enjoy literature--as you remember what you read ! A.What's your motivation? B.Practice makes perfect. C.It's a bit like reading a foreign language. D.Marking helps you remember what you read. E.Memory is sometimes a tricky thing. F.But other books require a bit more work on your part. G.You can do the same thing when you are reading the text!
If you could change your child's DNA in the future to protect them against diseases, would you? It could be possible because of technology known as CRISPR- Cas, or just CRISPR. CRISPR involves a piece of RNA, a chemical messenger, designed to work on one part of DNA； it also uses an enzyme (If) that can take unwanted genes out and put new ones in, according to The Economist. There are other ways of editing DNA, but CRISPR will do it very simply, quickly, and exactly. The uses of CRISPR could mean that cures are developed for everything from Alzheimer's to cancer to HIV. By allowing doctors to put just the right cancer-killing genes into a patient's immune system, the technology could help greatly. In April scientists in China said they had tried using CRISPR to edit the genomes (基因组)of human embryos. Though the embryos would never turn into humans, this was the first time anyone had ever tried to edit DNA from human beings. With this in mind, the US' National Academy of Sciences plans to discuss questions about CRISPR s ethics(伦理问题).For example? CRISPR doesn't work properly yet. As well as cutting the DNA it is looking for, it often cuts other DNA, too. In addition, we currently seem to have too little understanding of what DNA gives people what qualities. There are also moral questions around playing God”. Of course, medicine already stops natural things from happening-for example, it saves people from infections. The opportunities to treat diseases make it hard to say we shouldn't keep going. A harder question is whether it is ever right to edit human germ-line(种系)cells and make changes that are passed on to children. This is banned in 40 countries and restricted in many others. However, CRISPR means that if genes can be edited out, they can also be edited back in. It may be up to us as a society to decide when and where editing the genome is wrong. Also, according to The Economist, gene editing may mean that parents make choices that are not obviously in the best interests of their children: “Deaf parents may prefer their children to be deaf too； parents might want to make their children more intelligent at all costs. In the end, more research is still needed to see what we can and can't do with CRISPR. “It's still a huge mystery how we work,” Craig Mello? a UMass Medical School biologist and Nobel Prize winner, told The Boston Globe, "We're just trying to figure out this amazingly complicated thing we call life. 1.What is the passage mainly about? A.What we can and can't do with CRISPR. B.How CRISPR was developed by scientists. C.The advantages of CRISPR and arguments about its ethics. D.Scientists' experiments of using CRISPR to edit human embryos. 2.According to the passage, the technology of CRISPR . A.is very safe because it only cuts the DNA it is looking for B.is banned in most countries and restricted in many others C.could cause parents to make unwise choices for their children D.could help us discover the link between DNA and the qualities it gives people 3.It can be inferred from the passage that . A.all diseases could probably be cured through the uses of CRISPR B.scientists had never edited genomes before CRISPR was invented C.CRISPR is a technology that uses an enzyme to work on RNA and DNA D.CRISPR has proven to be the most effective way to protect children against diseases 4.What is the author's attitude towards CRISPR? A.Supportive. B.Worried. C.Negative. D.Objective.
A black hole is created when a large star burns out. Like our sun, stars are unbelievably hot furnaces(熔炉)that burn their own matter as fuel. When most of the fuel is used up, the star begins to die. The death of a star is not a quiet event. First there is a huge explosion. As its outer layer is blasted off into space, the dying star shines as brightly as a billion suns. After the explosion gravity pulls in what's left of the star. As the outside of the star sinks toward the center, the star gets smaller and smaller. The material the star is made of becomes tightly packed together. A star is so dense that a teaspoon of matter from it weighs billion of pounds. The more the star shrinks, the stronger the gravity inside it becomes. Soon the star is very tiny, and the gravity pulling it in is unbelievably strong. In fact, the gravity is so strong that it even pulls light into the star! Since all the light is pulled in, none can flee. The star becomes black when there is no light. Then a black hole is born! That's what we know about black holes. What we don't know is this: What happens inside a black hole after the star has been squeezed into a tiny ball? Does it keep getting smaller and smaller forever? Such a possibility is hard to imagine. But if the black hole doesn't keep shrinking, what happens to it? Some scientists think black holes are like doorways to another world. They say that as the star disappears from our universe, it goes into another universe. In other words a black hole in our universe could turn into a “white hole” in a different universe. As the black hole swallows light, the white hole shines brightly-somewhere else. But where? A different place, perhaps, or a different time-many years in the past or future. Could you travel through a black hole? Right now, no. Nothing we know of could go into a black hole without being crushed. So far the time being, black holes must remain a mystery. Black holes are a mystery-but that hasn't stopped scientists from dreaming about them. One scientist suggested that in the future we might make use of the power of black holes. They would supply all of Earth's energy needs, with plenty to spare. Another scientist wondered if a black hole could some day be used to swallow earthly waste-a sort of huge waste disposal(处理)in the sky! 1.When the star begins to die, . A.there is no fuel left in it B.its outer layer goes into space first C.it will explode and then become smaller D.it doesn't give off light any longer 2.Which of the following doesn't help produce a black hole? A.The star becomes very tiny and dense. B.The light can't go out of the star. C.The gravity inside the star is very strong. D.The dying star shines very brightly. 3.What can we know from the passage? A.A star will blast and die when it lacks fuel to support its burning. B.A black hole can swallow everything because it becomes smaller all the time. C.Man can never travel through a black hole but can make use of its power. D.Scientists have found that a black hole goes into another universe and becomes a white hole. 4.What's the best title for this passage? A.A New Scientific Discovery: Black Holes B.How Do Black Holes Come into Being? C.What Are Black Holes? D.Travel Through A Black Hole
I am the proud owner of three pet dogs. Over the years, I have watched their behaviours carefully that help me when I travel around the world. One important lesson that my dog, Cody, taught me is how to deal with little problems in life. From his calm behavior when someone knocked unexpectedly at the door to the indifferent way he has dealt with his recent serious illness, he has always had the same easy-going attitude. This attitude is an important lesson to me in how I can face difficult situations when travelling, I've learned to try to handle bad situations calmly, such as when we miss a train? lose luggage? and so on. Another dog of mine, Preston, loves to walk around the yard, spending hours smelling every place and finding out what it means to him. Taking it slowly is another lesson that's been very hard for me to learn. As an active traveller, I am actually experiencing less by speeding through everything, rather than slowly getting to know a place. Even if it means that you won't see as many things, going slowly when you travel is the only way to really get to know a new place. Rushing around a foreign city isn't fun at all. My dog, Moya, came from a truly bad situation. I am not sure what happened to her before； I just know it wasn't good. And while she has become more relaxed over the years, she is still slightly on edge. She is very cautious when faced with any new situation. But once she's accustomed to her new surroundings, she is fine. She doesn't let fear influence her experience. The same can be applied to our travel experience. No matter where we go, we need to manage new situations with caution--while at the same time not letting that caution turn into fear. Many thanks to my pets. Truly speaking, pets are as basic to American culture as hot dogs or apple pies. To Americans, pets are not just property, but a part of the family. After all, pets are people, too, with the help of whom I am able to gain a lot and live differently. 1.One of the three dogs, Cody,_______ . A.once suffered from a serious illness B.is excited when under pressure C.enjoys walking around the yard D.is unable to deal with new situations 2.From Preston, the author learned that one should ______. A.pay attention to the details in life B.try to see as many things as possible when travelling C.stay indifferent to strangers D.travel around slowly and have fun 3.The underlined phrase "on edge" in the fourth paragraph probably means “_____ ”. A.hungry B.nervous C.calm D.angry 4.Which of the following best shows the structure of the passage? A.

阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。 Carl lost his job. He tried to find another one but it wasn’t easy. As a result, the poor fellow couldn’t pay his bills and he couldn’t even find anybody to lend him any. Carl spent most of his days at home. Sometimes he looked out of the window and watched his neighbor’s house. An old professor lived there alone. Strangely, he hardly talked to his neighbors. Carl could see into the professor’s house because he never drew the curtain. The rooms were full of antique(古董) furniture and vases. Carl thought, “If I got an antique vase, I could sell it for a lot of money.” Every day Carl saw the professor. He left at 10 o’clock in the morning and came back home at 4 o’clock in the afternoon. He had a dog. Carl often went to the fence and played with it or gave it a piece of meat. One day Carl thought, “I will go into the professor’s house and steal a vase. I will break the window and climb in. The dog is not a problem.” There was an old gun in the cellar(地下室). It had been his great grandfather’s favorite thing a long time before. Carl didn’t want to use the gun but he thought, “Anything could happen.” He wanted to hide the gun under his coat but it was too long so he had to cut the end off with a saw(锯). The next morning he watched the professor leaving home at 10 o’clock. Carl climbed over the fence. The dog ran to him and Carl gave it a big bone. He threw a piece of stone through the window, which broke. It wasn’t high. He could climb into the house easily. He looked around inside. There were paintings on the walls, small figures and vases on the shelves and the floor. Carl didn’t know much about arts. He couldn’t choose.

课文语法回顾 All scientists subscribe to the view that the increase in the earth’s temperature is due to the burning of fossil fuels like coal, natural gas and oil to produce energy. Some byproducts of this process1. (call) “greenhouse” gases, and the most important one of2.is carbon dioxide. Dr. Janice Foster explained “There is a natural phenomenon3.is called the greenhouse effect. This is when small amounts of gases in the atmosphere, like carbon dioxide, methane and water vapour trap heat from the sun and therefore warm the earth. 4.for the greenhouse effect, the earth would be about 33 degrees Celsius cooler than it is. So, we need those gases. The problem begins when we add huge quantities of extra carbon dioxide into the atmosphere. It means that more heat energy tends to be trapped in the atmosphere 5. (cause) the global temperature to go up.

Radar（雷达） is an electronic device that detects planes, ships, coastlines, landmarks, and even storm clouds. The name radar comes from the first letters of the words radio direction and ranging. As the human eye uses light waves to see, radar “sees” with radio waves. Without radar, planes could not land safely in bad weather and ships could not move safely in thick fog.1. In the 1800s it was discovered that radio waves could be reflected from objects. But scientists did not make great advances in radar research until the 1930s, when the world was threatened by war.2. It has been used widely in almost every conflict since then. Echoes make it possible for radar to work. When a beam of radio waves is sent out, it strikes on an object and returns an echo. This echo is picked up by radar and recorded on a screen similar to television screen. On the screen an observer sees a flash, or a blip, that shows the direction and distance of the object.3. Airport control towers use radar to guide planes in for safe landings. Almost all large ships depend on radar to prevent collisions with icebergs or other ships. 4.Weather forecasters “see” the size, direction, and speed of storms on radar screens. Astronomers can even use radar to measure accurately the distance to the moon. Thus, the device has generated major advancements. 5. Huge radar antennas have been installed all over the United States. They guard us against possible enemy attacks. We have ballistic—missiles (战略导弹)warning systems that can alert us to attacks when missiles are more than 1,000 miles away. Other radar systems warn us against enemy aircraft and even spying space satellites. A. Police track speeders in radar-equipped cars. B. These measurements are now highly accurate. C. The device can be used in a wide range of fields. D. During World War II many countries used radar effectively. E. It is therefore especially valuable to shippers and travelers. F. Today radar is used by commercial airliners and weather forecasters. G. Strengthening national defense is one of radar’s most important functions.
Sea turtles are one of several species that have temperature-dependent sex determination. The number of female babies increases when nests are made in warmer sands. A recent study by the National Oceanic and Atmospheric Administration, California State University and Worldwide Fund for Nature Australia examined two genetically distinct populations of green sea turtles living in the Great Barrier Reef. The study found that a group of about 200,000 turtles living in the northern part of the reef was almost entirely female. While the southern population was 65 to 69 percent female, females in the northern group accounted for 99.1 percent of young turtles and 86.8 percent of adults. After combining their results with temperature data, the scientists in charge of the study found that the northern green turtles have been producing mainly females for more than two decades and that the complete feminization(雌性化) of this population is possible in the near future. The temperature at which the turtles will produce male or female babies can be passed on to the turtles' children. Most sea turtle populations are now producing offspring above the most suitable temperature, making it clear that climate change causes a serious threat to the survival of these populations. The chief executive Of World Wildlife Fund Australia, Dermot O'Gorman, said this is another sign of the impact of climate change, following recent research that shows that coral bleaching (珊瑚白化) events are occurring far more frequently than in the past. “We've had two years where we've had mass bleaching events on the Great Barrier Reef,” he told Guardian Australia. “That's a very visible sign of the impact of climate change. But this is a quiet change. We can't see the impact it's having on a turtle population until a study like this shows some long-term trends.” The lead author of the paper, Dr Michael Jensen, said the findings represent a major environmental conservation issue. O'Gorman said more urgent action on climate change is clearly needed, adding that some conservationists have already taken practical measures, such as using shade cloth on turtle nesting beaches to lower the sand temperature, and reducing bycatch(误捕) in the fishing industry. "Shade cloth can be used in certain places, but there's a limit to the scale you can do that, " he said. "Now every large male who can reproduce is going to be even more important. 1.According to the research on Great Barrier Reef's green sea turtles, __________. A.about 65 to 69 percent of northern turtles are female B.86.8 percent of southern turtles have grown up to adults C.the feminization of green sea turtles could become worse D.adult green Sea turtles can change their sex in warmer places 2.Why did O'Gorman mention coral bleaching? A.To suggest that climate change poses more risks to coral than turtles. B.To compare the living environments of turtles and coral. C.To urge people to take practical measures to fight climate change. D.To stress this discovery about green sea turtles is very valuable. 3.Conservationists are taking action to __________. A.keep the sea turtles' nests cool B.stop the illegal fishing of green sea turtles C.expand the size of the green sea turtles' nesting places D.build special nests for turtles to produce offspring 4.Which would be the best title for the article? A.How climate change affects ocean creatures B.Invisible change caused by global warming exposed C.Necessity of protecting green sea turtles and their habitat D.Global green sea turtle populations in greater danger
Aging happens to all of us, and is generally thought as a natural part of life. It would seem silly to call such a thing a “disease”. On the other hand, scientists are increasingly learning that aging and biological age are two different things, and that the former is a key risk factor for conditions such as heart disease, cancer and many more. In that light, aging itself might be seen as something treatable, the way you would treat high blood pressure or a vitamin deficiency. Biophysicist Alex Zhavoronkov believes that aging should be considered a disease. He said that describing aging as a disease creates encouragement to develop treatments. “It unties the hands of the pharmaceutical(制药的) industry so that they can begin treating the disease and not just the side effects,” he said. “Right now, people think of aging as natural and something you can't control.” he said. “In academic circles, people take aging research as just an interest area where they can try to develop interferences. The medical community also takes aging for granted, and can do nothing about it except keep people within a certain health range. ” But if aging were recognized as a disease, he said, “It would attract funding and change the way we do health care. What matters is understanding that aging is curable.” “It was always known that the body accumulates damage” he added. “The only way to cure aging is to find ways to repair that damage. I think of it as preventive medicine for age-related conditions. ” Leonard Hayflick, a professor at the University of California, San Francisco, said the idea that aging can be cured implies the human lifespan can be increased, which some researchers suggest is possible. Hayflick is not among them. “There're many people who recover from cancer, stroke, or heart disease. But they continue to age, because aging is separate from their disease,” Hayflick said. “Even if those causes of death were removed, life expectancy would still not go much beyond 92 years.” 1.What do people generally believe about aging? A.It should cause no alarm whatever the circumstances. B.It should be regarded as a kind of disease. C.They just cannot do anything about it. D.They can delay it with advances in science. 2.How do many scientists view aging now? A.It might be prevented and treated. B.It can be as risky as heart disease. C.It results from a vitamin deficiency. D.It is an irreversible(不可逆转的) biological process. 3.What do we learn about the medical community? A.They now have a strong interest in research on aging. B.They differ from the academic circles in their view on aging. C.They have ways to prevent people's aging process. D.They can contribute to people's health only to a limited extent. 4.What does Professor Leonard Hayflick believe? A.Aging is hardly separate from disease. B.The human lifespan cannot be lengthened. C.Few people live up to the age of 92. D.Heart disease is the major cause of aging.
"I didn't hear them call my name," explained Shelley Hennig to Active Teens (AT) as she talked about that exciting moment on national television when she won the honor of Miss Teen USA 2004. "Are you ready?" is what she heard. Then she said, "I shook my head no, and then they said ‘yes’ and it was announced again." It was four days after that life changing moment for the seventeen-year-old high school student from Destrehan, Louisiana----she was still______． "I was so shocked! I never believed that it could actually really happen." Present in the audience（观众）that day were: her mother and father, older brother, her friends, and her dance teacher.

She's been through so many difficulties and came through them all. I've learned to get over bad life's experiences and learned how to move on because of her." One of those bad life's experiences for Shelley happened three years ago when her brother Brad was killed in a drunk driving accident. He was 18. She found writing helped her get through the rough days. She said, "I write a lot about my brother. I write a lot, a lot, a lot...” As Miss Louisiana Teen, she traveled around the state speaking to teens（青少年）about the dangers of drinking and driving. In her role as Miss Teen USA, Sheiley will continue to speak to youth about safe driving, in addition to many other things to help the youth. When AT asked Miss Teen USA if she had any advice for our readers, she said, "Don't let anyone change you. Hang out with people that make you feel good about yourself. That way, it is easy to be yourself." 1.What do the words “on cloud nine” in Paragraph 2 probably mean?
