A US student has just spent 30 days on an “insect diet ” – eating insects three times a day. Camren Brantley-Rios says traditional meats such as pork and beef are unable to continue and he wanted to try out what many consider the diet of the future.
Many people would not like the idea of eating insects distasteful, even if it were not disgusting. Not so long ago Brantley-Rios was among them. But for the last month he has been eating insects for breakfast, lunch and dinner.
“I’m mainly sticking to three kinds,” he says.
Occasionally he has included different insects. Preparing these he “actually cried”, though he insists they were surprisingly good.
Insects consume fewer resources than animals, like pigs and cows, to produce the same amount of protein(蛋白质), Brantley-Rios says – and more than two billion people worldwide include insects in their regular diet, according to the UN Food and Agriculture Organization.
“There’s not really a need to eat insects in America because we have it so nice,” Brantley-Rios says. “We have finer meats and we’re lucky to have that luxury(奢侈), so there’s not much of a pressure to eat insects right now. But what a lot of people are trying to do is make it a little bit more marketable.”
He has ordered insects from farms that usually supply zoos, which need them “to feed certain animals”. He has always made sure the insects have been fed on an organic diet, he says, and only bought species he knows are safe to eat.
He knows that one person eating insects won’t make much difference. To have a real environmental effect, millions would have to follow his example.Why has the US student tried out an “insect diet”?
| A．To seek for future vegetables. |
| B．To advocate traditional meats. |
| C．To make up for the lack of meat. |
| D．To explore new forms of protein. |

| A．He is tired of meats like pork and beef. |
| B．He didn’t like the idea of eating insects. |
| C．He had nothing to eat but insects last month. |
| D．He advised people to eat insects though disgusted. |
What does the underlined part “actually cried” in Paragraph 5 mean?
| A．was scared | B．was pitiful |
| C．was sorry | D．was puzzled |
How does Brantley-Rios guarantee the safety of his insect diet?
| A．He tests each species before eating it. |
| B．He has insects raised on his own farm. |
| C．He feeds his insects on an organic diet. |
| D．He orders insects for certain zoo animals. |
Parents and kids today dress alike, listen to the same music, and are friends. Is this a good thing? Sometimes, when MR. Ballmer and his 16-year-old daughter, Elizabeth, listen to rock music together and talk about interests both enjoy, such as pop culture, he remembers his more distant relationship with his parents when he was a teenager.
‘‘I would never have said to my mom, Hey, the new Weezer album is really great. How do you like it?”says Ballmer. There was just a complete gap in taste. Music was not the only distance. From clothing and hairstyles to activities and expectation: earlier generations of parents and children often appeared to move in separate orbits.
Today, the generation gap has not disappeared, but it is getting narrow in many families: Conversations on subjects such as sex and drugs would not have taken place a generation ago. Now they are comfortable and common. And parent-child activities, from shopping to sports, involve feeling of trust and friendship that can continue into adulthood.
No wonder greeting cards today carry the message, "To my mother, my best friend."
But family experts warn that the new equality can also result in less respect for parent. “ There's still a lot of strictness and authority on the part of parents out there, but there is a change happening," says Kerne, a psychology professor, at Lebanon Valley College. "In the middle of that change, there is a lot of confusion among parents."
Family researchers offer a variety of reasons for these evolving roles and attitudes. They see the 1960s as a turning point. Great cultural changes led to more open communication and a more democratic（民主） process that encourages everyone to have a say,
“My parents were on the 'before' side of that change, but today's parents. the 40-year-old were on the 'after' side," explains Mr. Ballmer. "It's not something easily accomplished by parents these days, because life is more difficult to understand or deal with, but sharing interests does make it more fun to be a parent now."
Which of the following shows that the generation gap is disappearing?
| A．Parents help their children develop interests in more activities. |
| B．Parents put more trust in their children's abilities. |
| C．Parents and children talk more about sex and drugs. |
| D．Parents share more interests with their children. |
The change in today's parent-child relationship is ________.
| A．more confusion among parents |
| B．new equality between parents and children |
| C．less respect for parents from children . |
| D．more strictness and authority on the part of parents . |
By saying "today's parents, the 40-year-olds, were on the “after' side." the author means that today's parents _________.
| A．follow the trend o f the change |
| B．can set a limit to the change |
| C．fail to take the-change seriously |
| D．have little difficulty adjusting to the change |
The purpose of the passage is to ________.
| A．describe the difficulties today's parents have met with |
| B．discuss the development of the parent-child relationship |
| C．suggest the ways to handle the parent-child relationship |
| D．compare today's parent-child relationship with that in the past |
China is going green.In order to reduce air pollution and oil shortages, automobile manufacturers have announced their plans to develop hybrid vehicles (混合燃料汽车) for the Chinese market. Toyota's hybrid car Prius will be ready to drive in China this week. Let's have a look at the new car.
Any vehicle is a hybrid when it combines two or more sources of power. Hybrid cars run off a rechargeable battery and gasoline. Hybrid cars have special engines, which are smaller than traditionalgasoline engines. They run at 99 percent of their power when the car is cruising (匀速行驶). A speciallydesigned battery motor provides extra power for running up hills or when extra acceleration is needed.
Step into a Prius, and turn on the engine. The first thing you notice is how much quieter it is than atraditional car. At this point, the car's gasoline engine is dormant (休眠). The electric motor will providepower until the car reaches about 24 km/h. If you stay at a low speed, you are effectively driving an electric car, with no gasoline being used, and no waste gas gives off.
The onboard(车载的) computer makes the decision about when to use a gas engine, when to goelectric, and when to use a combination of the two. If you go over 24 km/h, when you step on the gas pedal (油门), you are actually telling the computer how fast you want to go.
The electronic motor recharges automatically using a set of batteries. When driving at high speed, the gasoline engine not only powers the car, but also charges the batteries. Any time you use the brake, the electric motor in the wheels will work like a generator and produce electricity to recharge the batteries.As a consequence, the car's batteries will last for around 200,000 miles.The author writes this passage mainly to________.
| A．teach people how to drive a hybrid car |
| B．show how to save their gasoline when driving a car |
| C．introduce a new kind of "green" car |
| D．announce plans to develop hybrid vehicles for China |
The first sentence probably refers to ________.
| A．there will be more and more green land in China |
| B．China has started producing environmentally friendly cars |
| C．China's new cars are combinations of different green models |
| D．China is still young and lacking experience |
What is the most important feature of hybrid cars?
| A．They have smaller engines than traditional gasoline ones. |
| B．They are much quieter than traditional cars. |
| C．They only use 99 percent of their power to run up hills. |
| D．They are powered by both a rechargeable battery and gasoline. |
It was time for Mr. Rocco to shut up shop when I hurried into the florist’s. “Now, what is it that you want?” Mr. Rocco turned to me. “I want the most beautiful flower you have.” I replied, “And just how much do you have to pay for this most beautiful flower?” I held out a wet hand showing a quarter and dime. He nodded, and then showed me a plant on the counter “I can give you this one for 35 cents.” he said，“ Aw, gee,” I protested, “it looks like a weed!” About l 8 inches high, the plant was in a small pot covered with faded red paper.“ Now trust me, boy---I promise that tomorrow morning when you get up, you will find your most beautiful flower. ”said Mr. Rocco. I knew him to be a good honest man, so I agreed to take it.
It was almost midnight when I arrived home. Mom was seriously sick and using the front bedroom. I looked in to see if she was asleep, and then quietly tiptoed in and set the plant on the table beside her bed. I wanted her to be surprised when she woke on Mother’s Day. The next morning, I dressed and hurried downstairs. The sun was shining through kitchen window as I looked into Mom’s room. She motioned for me to come in, then glanced over at the table where the plant was. Holy mackerel! There were three big yellow trumpet-shaped blooms. It was just like Mr. Rocco said---the most beautiful flower I ever saw! When I looked at Mom, she was smiling as tears streamed down her cheeks. She held out her hand for me to come near, then pulled me close and hugged till it hurt. Then, remembering her contagious condition and that she wasn’t supposed to touch me, she quickly let me go.
My dear Mom died the next night. The moment she hugged me turned out to be the most wonderful moment of my life. Not only had that beautiful plant helped show just how much I loved her, but I'd always know how much she loved me.

All over the world, and for many different reasons, there are millions of people who rarely or never eat meat. These people are called vegetarians. To people who eat meat, being a vegetarian may seem like a very strange thing, diets for several different reasons.
First, vegetarians have an enormous health advantage. One of the major health problems in modern societies is not too much protein but too much fat, especially in the form of animal fats. Medical evidence suggests that animal fats, including butter, contribute to the development of cholesterol in the human body. High amount of cholesterol seem to be part of the cause of heart disease. Most vegetarians have low level of cholesterol. High amounts of animal fats also seem to lead to certain kinds of cancer, and vegetarians are typically less vulnerable to these cancers than people who eat a lot of meat. Overall, studies comparing the health of vegetarians and meat-eaters show that the meat-eaters are twice as likely to die of heart disease as vegetarians are.
Better health is one reason that people choose to become vegetarians. Another reason is religion. Some religions forbid the eating of meat. The largest of these is the Hindu religion, which has about 600 million believers in the world. Although not all Hindus are vegetarian, many are, and there are many believers of other religions such Buddhism and even some Christian religions that also do not eat meat.
Many vegetarians do not eat meat simply because they do not like the taste of it. They have no religious or philosophical reasons; they just do not like meat. Another important reason that vegetarians give for not eating meat is the health advantages that were given above. Lastly, there are many people who do not eat meat because they just do not like the idea of killing animals for food. They believe that life, all life, is valuable , and that we do not have to destroy life to feed ourselves when there are other good sources of food.According to the passage, people choose to be vegetarians for the following reasons EXCEPT________.
| A．they want to stay healthy |
| B．they are too kind to put the idea of killing animals |
| C．they live in areas where meat supply is not adequate |
| D．they should not eat meat due to their religious belief |
Which of the following is true according to Paragraph 2 ?
| A．Vegetarians enjoy a more healthy life than the meat eaters. |
| B．Heart disease and cancer are caused by large amounts of protein. |
| C．There are twice as many meat-eaters as vegetarians who die of cancer. |
| D．There are less health problems in modern society due to advanced medical care. |
What does “vulnerable” mean in Paragraph 2?
| A．Having low level of cholesterol. |
| B．Having high level of cholesterol. |
| C．Having weak ability to resist diseases and harms. |
| D．Having strong ability to resist disease and harms. |
It can be inferred from the passage that __________.
| A．being a vegetarian may be a very strange thing |
| B．vegetarians eat meat on some special occasions |
| C．all vegetarians have reasons for their not eating meat |
| D．most vegetarians believe that life without meat is happy. |
A new planet-hunting technique has detected the most earth-like planet yet around a star other than our sun, raising hopes of finding a space rock that might support life, astronomers (天文学家) reported recently.
“This is an important discovery to answer the question ‘Are we alone?’” said Michael Turner of the National Science Foundation.
“The team has discovered the most earth-like planet yet, and more importantly, has proved the power of a new technique that is sensitive (灵敏的) to detecting planets that are fit for people to live on,” Turner said in a statement.
In the last decade, astronomers have detected more than 160 planets moving around stars outside our solar system. Most of these have been gas giant planets like Jupiter, which are unfit for life.
But an international team has detected a cold planet about 5.5 times more massive than the earth — still small enough to be considered earth-like — moving around a star about 20,000 light years away, close to the center of the Milky Way.
To find this new planet, the team used a technique called gravitational microlensing (引力微观透镜法). When a planet is circling the closest star, the planet’s gravity can add its own signature to the light. This kind of light signature was observed on July 11 by a group of telescopes in a project known as OGLE, short for Optical Gravitational Lensing Experiment.
“The main advantage of microlensing is the signals for low-mass planets: They’re not weak signals. They’re just rare,” Bennett of the University of Notre Dame in Indiana said by telephone. “If there happens to be a straight line between a foreground star with its planet and the background source star, then you’re able to detect that planet.”The underlined word “detected” in Paragraph 1 probably means “_________”.
| A．discovered | B．destroyed |
| C．created | D．searched |
The author’s purpose in writing this passage is to ____.
| A．prove that scientists have a lot of difficulties in doing scientific research |
| B．explain why this planet moves around a star like our sun |
| C．teach the readers some basic knowledge about the universe |
| D．tell people about a new technique that finds the most earth-like planet moving round another star |
From the news report we can infer that _________.
| A．the planet is like the earth because it is close to the center of the Milky Way |
| B．it is quite possible that life may exist on other planets in the universe |
| C．people have no interest in finding a planet that might support life |
| D．the question “Are we alone” is too difficult for scientists to answer |
Which of the following statements is NOT true according to the passage?
| A．The signals coming from low-mass planets are too weak to be noticed. |
| B．Most of the discovered planets are not fit for people to live on. |
| C．If a star with its planet happens to be in line with the source star, then the planet can be found. |
| D．The power of the new technique is proved by the discovery of the earth-like planet. |
