Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.

The greatest thing that gene technology can do is to 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. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, 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 on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span (寿命) can be prolonged.

Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial (皇家的) family being a good example, have hereditary diseases. This means 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 hereditary diseases. But gene technology can solve this problem perfectly. The scientist 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 manufacture 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 soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.

1.What does “them” in the second paragraph refer to ?

A. People with cancer or heart disease.

B. Millions of people with serious diseases.

C. Some diseases doctors can do nothing with.

D. The two illnesses of cancer and heart disease

2.What can gene technology do according to paragraph three?

A. It can help the English imperial family out.

B. It can be used to clone human babies.

C. It can help people to give birth of a baby.

D. It is likely to treat hereditary diseases.

3.What are people worried about according to the passage?

A. Human babies may be cloned in a large scale.

B. Healthy human babies will soon be cloned.

C. Scientists may well find the wrong genes.

D. The government may not control gene techs.

4.This passage is mainly written to _________________.

A. show gene technology will benefit people

B. show gene technology will do harm as well

C. tell that gene technology is a hot topic

D. tell that gene technology is growing fast

A group of people from Denmark have formed the B-Society. According to them, human beings are divided into types: A-People, and B-People. A-People have no problem getting up in the morning, and operate much better earlier in the day. However, B-people are better later in the day. “I’m useless early in the morning,” says one of the members of the B-Society.”All I can do is drink coffee, and stare into space. People used to get up early because they had to feed the animals. But I haven’t got any cows or chickens, so I can sleep late,” She adds. Since the society was set up, the B-Society has welcomed several thousand members.

Right now, the B-Society is fighting hard for businesses to join its B-certification (证明) list. Companies that are “B-certified” basically give their employees the opportunity to come in when they want. In some companies, employees arrive at any time up to 3:30 pm --- each to their own rhythm (节奏).

And it is not just businesses that are benefiting from this. Teenagers who can’t get out of bed in the morning, and parents who never quite get the kids to school on time, can now benefit from B-classes. From next year, a school in Copenhagen will offer classes which start later in the day (at 10 instead of eight). And even the government seems to like the idea.

The B-Society was founded by Camilla Kring, a professor from the University of Copenhagen. On her website, she says, “When B-people’s work rhythms are considered at the work place, their productivity (生产力) and quality of life is increased, which can increase productivity for the entire organization.

She adds that, “B-Society will create a new daily rhythm in schools and other institutions (机构) as an alternative to the current rhythm of ‘early at work and early at home’. We are working for the establishment of kindergartens, primary and secondary schools as well as universities that open between 10 am and 8 pm.”

Would you like to work for a B-certified company?

1.According to the text, who belong to the B-Society?

A. Late risers.   B. Businessmen.

C. Animal lovers. D. Sleep experts.

2.In B-certified companies, employees can ____.

A. get more working opportunities

B. join any other companies

C. work on any days they choose

D. go to work at any time of a day

3.In Camilla Kring’s opinion, B-people _______.

A. are more hard-working than A-people

B. have a better quality of life than A-people

C. are more productive if given more freedom

D. like the rhythm of “early at work, early at home”

4.The author’s purpose in writing this text is to _____.

A. stress the importance of getting up early

B. express his attitude towards the B-Society

C. introduce a group having a special daily rhythm

D. call on people to work for B-certified companies

Nowadays more and more people who lives in cities like to keep dogs as pets. Some of my friend believe people can get comfort and develop their patient and love by keeping dogs as pets. Personally, I do not really have interest to dogs, and sometimes I do hate some dog owners. They can be so annoyed. They talk about their dogs as if they are actually their little babies. Some dogs make too much noise at night, that makes it hard for people living nearby fall asleep. Besides, not all dog owners think of others while they are walking their dogs. As really annoys me, though, is the way they let their dogs get out of the control.
