Last Thursday, we had a class meeting to discuss where to go for us spring outing. We came up with several choices such as going the boating, climbing a mountain, and go to an amusement park. Finally, we decide to go mountain climbing.

The next day，we set off in the earlier morning. While climbing the mountain, we enjoyed the warm sunshine or a beautiful view.

Help Hermit Crabs

Hermit crabs are nature’s recyclers. They eat waste and help keep oceans and shores clean. Unlike other crabs, the hermit crab has a thin outer shell over its soft tail. This makes the hermit crab easy prey for hungry predators (天敵). Hermit crabs stay safe by living in old seashells. A hermit crab is picky (狡猾); it tries on many shells until it finds one that fits just right. In recent years, however, many hermit crabs have had trouble finding their perfect homes. What is the problems There are not enough shells to go around!

One reason for the seashell shortage is that ocean water is not as clean as it once was. This has caused chemical changes to sea water. Some sea animals, like snails, are affected by these changes. Now there are fewer snails making shells. People visiting the beach often take shells home as souvenirs (紀念品). This is another problem. Other people even take shells for their own pet hermit crabs! They do not realize that hermit crabs in the wild need those shells too.

Now people are working to solve this hermit crab housing shortage. They are teaching beach-Boers to leave seashells where they belong--at the seashore! Some people even make fake seashells that they hope the hermit crabs will like. For example, a group called Project Shelter invited people who visited their website to create different designs for hermit crab shells.

These designers had a lot to consider. What kind of material should be used to build a seashells. The material must be light enough for the hermit crab to carry, but strong enough to protect the crab from predators. The man-made shells could not contain glue or any other substance (物質) that might harm a hermit crab. Another challenge with building a hermit crab home was the opening to the shell. Too big would mean the crab would not feel safe. Too small would be uncomfortable, and the crab would not want to move in.

The Project Shelter shells are placed in the wild for hermit crabs to find. Lucky hermit crabs can move into these new dream homes.

【題目】 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.

【1】What'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.

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

A.B.

C.D.

【3】Where is the text probably from?

A.A story book.B.A magazine.

C.A science fiction.D.A novel.

【題目】

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.

【1】Which 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.

【2】What 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.

【3】Which 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.

【4】What 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.
