【题目】 Recently there was a major discovery in the scientific research—the mapping of all DNA in a human gene is complete. Several years ago, it seems an impossible task for scientist to accomplish. All this progress in science leads us to believe that the day when human being will be cloned is not far away. Human cloning has always been a topic of argument in terms of morality (道德) or religion.

Taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning. Moreover, cloning would enable women who can't get pregnant to have children of their own.

Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organs. This surely would be greatly beneficial to millions of unfortunate people around the world who are expected to lose their lives due to organ problems. It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists.

However, arguments against cloning are also on a perfectly practical side. Primarily, I believe that cloning would step in the normal "cycle" of life. There would be a large number of same genes, which reduce the chances of evolution, since it may be difficult for living creatures to naturally adapt to the ever-changing environment, which will result in ultimate disappearance. Furthermore, cloning would make the uniqueness that each one of us possesses disappear. Thus, leading to creation of genetically engineered groups of people for specific purposes and, chances are that those individuals would be regarded as "objects" rather than people in the society.

Scientists couldn't surely guarantee that the first cloned humans will be normal. Thus this could result in introduction of additional limitations in the human "gene-pool".

Regarding such arguable topics in "black or white" approach seems very innocent. We should try to look at all "shades" of it. I believe that cloning is only legal if its purpose is for cloning organs; not humans. Then we could regard this as for "saving life" instead of "creating life". It is believed that cloning humans is morally and socially unacceptable.

1What's the author's opinion on cloning?

A.Cloning should be entirely banned.

B.Cloning should be used in creating life.

C.Cloning will take away the right to reproduce.

D.Cloning is acceptable if it is used for cloning organs.

2Which of the following shows the structure of the passage?

A.B.

C.D.

3Where is the text probably from?

A.A story book.B.A magazine.

C.A science fiction.D.A novel.

【题目】请阅读下面短文,并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。
The expression, “everybody's doing it,” is very much at the center of the concept of peer pressure. It is a strong influence of a group, especially of children, on members of that group to behave as everybody else does. It can be positive or negative. Most people experience it in some way during their lives.
People are social creatures by nature, and so it is hardly surprising that part of their self-respect comes from the approval of others. This instinct (天性) is why the approval of peers, or the fear of disapproval, is such a powerful force in many people's lives. It is the same instinct that drives people to dress one way at home and another way at work, or to answer “fine” when a stranger asks “how are you?” even if it is not necessarily true. There is a practical aspect to this: it helps society to function efficiently, and encourages a general level of self-discipline that simplifies day-to-day interaction.
For certain individuals, seeking social acceptance is so important that it becomes like an addiction; in order to satisfy the desire, they may go so far as to abandon their sense of right and wrong. Teens and young adults may feel forced to use drugs, or join gangs that encourage criminal behavior. Mature adults may sometimes feel pressured to cover up illegal activity at the company where they work, or end up in debt because they are unable to hold back the desire to buy a house or car that they can't afford in an effort to “keep up with the Joneses.”
However, peer pressure is not always negative. A student whose friends are good at academics may be urged to study harder and get good grades. Players on a sports team may feel driven to play harder in order to help the team win. This type of influence can also get a friend off drugs, or to help an adult take up a good habit or drop a bad one. Study groups and class projects are examples of positive peer groups that encourage people to better themselves.
Schools try to teach kids about the dangers of negative peer pressure. They teach kids to stand up and be themselves, and encourage them to politely decline to do things that they believe are wrong. Similarly, it can be helpful to encourage children to greet the beneficial influence of positive peer groups.

Right in front of the Minneapolis Central Library, a row of green bikes sits parked in a special stand. Each bike is designed with the logo “Nice Ride”-the name of the city's bike-sharing programme.

Nice Ride bikes are a lot like the library books that people come here to borrow. To rent a bike, you simply use your membership card at a Nice Ride bike station. Members can rent one of 1,200 bikes from 138 stations throughout Minnesota's largest city. People use the Nice Ride bikes to go to work, to go out on business, or just to enjoy the city's many bike paths.

The rise of bike-sharing programmes like Nice Ride is encouraging more people than ever to choose biking over driving. Skyrocketing gas prices and concerns about the environment have also gotten people to dust off their bike helmets, pump air into flat tires, and hit the road.

Why ride? Not only is biking good exercise, but switching from a car to a bike also cuts down the amount of pollution in the air. Carbon dioxide, a greenhouse gas linked to climate change, is one of the many polluting substances that come out of a car's tail pipe.

Bike-sharing systems are found around the world in cities like London, Paris, Barcelona, and Melbourne. The largest programme with 70,000 bikes-is in Wuhan, China.

To make roads friendlier to non-motorists, the US Department of Transportation has invested more than a billion dollars in cycling and pedestrian projects in recent years. The money went towards building thousands of miles of on-street bike lanes and pedestrian-only passages called greenways.

1Which of the following can people do with the bikes?

A.Earn a living.B.Enjoy bikeways.

C.Compete in a race.D.Rent them out to others.

2What is Paragraph 4 mainly about?

A.Benefits of biking.

B.Pollution caused by cars.

C.Methods to use the bikes.

D.Measures to decrease pollution.

3Which of the following is true of Nice Ride?

A.China has better public bike systems than it.B.It will take the place of taxi companies.

C.It attracts more people to choose biking.D.The government lacks money to support it.

4What is the author's purpose in writing this text?

A.To seek advice for Nice Ride.

B.To compare Nice Ride with libraries.

C.To raise money for bike-sharing programmes.

D.To introduce the bike-sharing system in public places.
