With the development of science and technology, the research of human genes is playing more and more important part in our daily life. Sometimes it is a hot topic drawing more and more attention.
Gene technology can cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. But if the gene technology is used, not only these two diseases can
be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend curing their diseases can be saved, therefore it benefits the economy as well. In addition, people can live longer.
Gene technology can help people to give birth to more healthy and clever children. Some families have hereditary diseases and their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about them. But gene technology can solve this problem perfectly. The scientists just need to find the wrong gene and correct it, and a healthy child will be born.
Some people are worrying that the gene research can be used to clone human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep; therefore these people predict that human babies would be cloned. But I believe cloned babies will not come out in large amounts, for most couples in the world can have babies in a very normal way. Of course, the governments must take care to control gene technology. What does "these two killers" in the 2nd paragraph refer to?
| A．Hereditary diseases and cloned baby. |
| B．The two murderers who killed people. |
| C．Cancer and heart disease. |
| D．Two treatments of the diseases including gene technology. |
The underlined word "hereditary diseases" (in Paragraph 3) probably means "__________".
| A．serious diseases | B．cancer | C．heart disease | D．family diseases |
What can we infer from the passage?
| A．The research of human genes is more and more important in our life. |
| B．Gene technology will benefit the national economy. |
| C．Cloning babies under the control of the governments is acceptable in the writer's eyes. |
| D．With the help of gene technology, human beings will turn into perfect species. |
What's the best title for this passage?
| A．Time for Controlling Gene Technology! |
| B．Cloning Babies, Good or Bad? |
| C．Human's Killers! |
| D．Gene Technology, the Helper of Human Being! |
Many French teachers and parents complain that their kids are less bright than they were. They say young people visit museums less often and spend too much time on the Internet. They only read comics and listen to music, and like American culture more than their own. But is this true? A recent survey shows that many French kids spend their time as other kids always have.
Most French teens love music, with 86% putting it as their top hobby, above the cinema, sport and television. French kids read a lot and like different things, from Japanese cartoons to American novels. Many French people worry that their children watch too many American films and listen to too much American music. But the results of this survey show that French young people like their own culture.

An allergy is a strong reaction to a substance. Many things can cause allergies. The most common cause is pollen (花粉), which is usually produced by trees in the spring, grasses in the summer and weeds in the fall, as part of their reproductive process.
Other causes include organisms, chemicals, plants and dead skin particles from dogs and cats can also cause allergic reactions. So can insect stings and some food.
The most common kind of allergic reactions is itchy (痒的) , watery eyes and a blocked or watery nose. Allergies can also cause red, itchy skin. Some reactions can be life-threatening, for example, when breathing passages become blocked.
It is not always easy to avoid allergies. Drugs may offer an effective treatment. Another treatment used in some cases is called immunotherapy. A patient is injected with small amounts of the allergy-causing substance. The idea is that larger and larger amounts are given over time until the patient develops resistance in his body.
In the United States, experts estimate that up to 8% of young children have food allergies. Every year these allergies cause about 30,000 cases with severe reactions that require immediate treatment. It can result in breathing trouble and in some cases death. It is said that about 100 to 200 people will die. It is said that most of the reactions are caused by peanuts and tree nuts like walnuts.
People can also be allergic to medicines. The American Academy of Allergy, Asthma and Immunology says about 10％ of bad reactions to commonly used medicines are allergic. In other words, a person’s immune system overreacts and produces an allergic reaction. The most common reactions include skin rashes, itching, breathing problems and swelling in areas such as the face.Allergies seldom occur in winter because ________.

| B．have immediate operations |
| C．be given the allergy-causing substance until the patient develops resistance |
| D．be exposed to enough allergy-causing substances |
The best title would be _______.

The way we get about has a deep influence on the way we live－affecting where we set up home, work and holiday. So what changes might come in the way we get around? What big ideas are out there, and do they have any chance of coming true?
Personal Air Travel
The idea: flying cars
Developments in light small plane technology will make it possible for everyone to own what are, in fact, flying cars. They will have closed cabins, heating, stereos and room for two people.
You will take off from a field near your home and fly to towns and cities. After landing, you will take off the fixed wing and continue your journey by road just as if you were traveling by car.
Fuel efficient engines and the advantage of being able to travel in the sky will keep costs and the environmental influence down.
Flying for Fun
The idea: Jet Packs
The idea was a hit when a stuntman (特技演员) flew around on one during the opening ceremony of the 1984 Los Angeles Olympics, which was very successful.
You’ll be able to use the equipment－roughly the size of two scuba tanks fastened to your back－for short journeys.
They will be handy for cleaning hard-to-reach windows, arriving in style at a party and shopping.
Taxis
The idea: driverless taxis
These computer-controlled taxis will take you wherever you want along a fixed route, whenever you want to go.
For the price of one person’s bus fare, several people can ride at speeds of up to 25 mph, and there will be fences to guard against accidents.
There will be little, if any, wait for the use of the taxis, which will leave from stations and will be used by prepaid cards.
The taxis, which will travel on a 1.5 m-wide track, will use 75% less energy per passenger than a car and 50% less than a bus.The passage is mainly about ________.
| A．future travel | B．big ideas and dreams |
| C．advanced technology | D．the influence of travel |
We learn from the passage that flying cars ________.
| A．will operate only in the sky |
| B．will be more expensive than common cars |

| D．won’t be equipped with things similar to what cars have |
With Jet Packs, we can do all the following EXCEPT ________.
| A．attend a party | B．clean high windows |
| C．go shopping | D．have a long journey |
As for driverless taxis, we can infer that ________.

Even when you’re extremely busy, you aren’t using your time with 100% efficiency. There are gaps in everyone’s schedule where they aren’t doing anything important. Even if your schedule has no gaps, there is probably lots of time when you aren’t working as fast or as effectively as you possibly could.
Why aren’t you completely efficient? It’s because time isn’t the limiting factor. If it were the limiting factor, people could work non-stop without breaks or any unproductive distractions (消遣). Instead, people, even those who are highly productive, need to take breaks, occasionally procrastinate (拖延) and slow down on tasks throughout the day.
The real and most important limiting factor for productivity is your energy levels to pay attention. Energy levels limit your productivity because when you’re tired, you can have enough time and still not get everything done. Your attention ability is also limited, because even if there are a million things that need to be done, you can only focus on one or two at a time.
You might not be able to insert another 4-5 hours into your schedule without making some sacrifices. But even extremely busy people can add an hour or two into their schedule without cancelling anything. The reason why it’s hard to “find time” isn’t a lack of time. It’s because you don’t have enough energy left to focus on something else that needs to fit into your day.
I first suspected time wasn’t the real problem during an extremely busy period in my life over a year ago. I was extremely busy, but at that time I still exercised regularly. I had daily to-do lists with over twenty items, and I still found time to exercise. However, after a few weeks off, due to illness, I stopped exercising. I was not busy by any standards, in fact, my schedule was incredibly light. Despite this free time, I found it hard to find time to exercise. It seemed to get pushed later and later into my schedule until it was gone. How can I explain this odd experience? I believe you have known it. If someone can’t work with 100% efficiency, the most important limiting factor is ________.
| A．a schedule without gaps | B．breaks and distractions |
| C．the limited time | D．the limited energy |
According to Paragraph 4, everyone, including the extremely busy people, can ________.
| A．work without any rest |
| B．focus on many things at a time |
| C．find some more time in a day |
| D．do some exercise regularly |
The writer gives the example of himself in the last paragraph in order to ________.
| A．prove what the real limiting factor is |
| B．show us how busily he needs to work |
| C．explain how important a healthy body is |
| D．tell us what an odd experience he has |
What is the best title of the passage?
| A．Do You Really Lack Time? |
| B．How Can You Work Efficiently? |
| C．What Makes Your Energy Limited? |
| D．When Should You Do Exercise? |
A girl became a volunteer in the activities of Deathbed Care, which meant visiting and taking care of a patient suffering from an incurable disease with days numbered.
The girl was assigned to look after an old man suffering from cancer whose children lived abroad. Their living conditions were not satisfactory while the old man had a lot of savings. She was expected to comfort him and keep up his spirits.
Every Saturday the girl came on time to keep him company, telling him stories. When he was having an intravenous drip (静脉滴注), she would help massage his arms. The doctor found the patient much improved mentally. The old man began to involve himself actively in the medical treatment and he seldom shouted at others.
But something that happened made the doctor uneasy and puzzled. Each time the girl left, the old man would give her some money. The doctor did nothing to interfere (干涉), unwilling to offend the old man. A month later the old man showed evident signs of decline after suffering coma (昏迷) a few times.
When rescued from the latest coma, the old man told the doctor his last wish, “I have deep sympathy for the girl. Will you be kind enough to help her finish her studies？”
But the doctor knew that her family was welloff and she had no difficulty pursuing her studies. Sometimes she even came to the hospital in her father’s car.
When the girl came at the weekend after the death of the old man, the doctor told her the bad news. She was very sad and burst into tears. Then she handed $ 500 to the doctor, saying, “The old man had all along thought I came to do the job because of poverty. He gave me money so that I could continue my schooling.” Now he got the answer to the puzzle.
