题目列表(包括答案和解析)
Tuvalu, north of Fiji, is a tiny country in the Pacific Ocean.
Storms and huge waves are a constant threat and none of Tuvalu's nine little islands is more than five metres above sea level. Salt water is already entering the country's drinking water supply, as well as damaging plants that produce fruit and vegetable.It fears it will be swallowed up by the sea. Without urgent help, the country's days are numbered.
But Tuvalu is not the first place to face sinking into the sea. Venice, a historic city in Italy best known for its canals, has sunk about 24cm over the past 100 years. Experts say that it will have sunk another 20-50cm by 2050. A century ago, St. Mark's Square, the lowest point in the city, flooded about nine times a year. Nowadays, it happens more than 100 times.
While Venice is slowly sinking into the mud on which it stands, Tuvalu's rising sea level is caused by global warming.
The average global temperature has increased by almost 0.5 centigrade degree over the past century; scientists expect it to rise by an extra 1-3 degrees over the next 100 years.
Warmer weather makes glaciers melt, adding more water to the ocean. The warmer temperatures also make water expand, so it takes up more space, causing the sea level to rise. The sea level has risen about 10-25cm in the last 100 years.
People have been increasing the greenhouse gases in the atmosphere, such as CO2, through burning coal, oil and gas. This adds to the power of the greenhouse effect, making the planet even warmer.
Many scientists believe that, if the warming is not stopped, there will be huge climate changes. The sea level could rise by one metre this century.
Should this come true, millions of homes would be swallowed up by the sea and the world will be flooded with "climate refugees" looking for somewhere else to live.
We can infer from Paragraph 2 that ______.
A. Tuvalu is in danger of being swallowed up by the sea
B. all Tuvalu’s islands are about five meters above the sea level
C. drinking water in Tuvalu has been destroyed
D. Tuvalu is often flooded by storms and waves

Believe it or not, oceans and seas are easy to be harmed by the development of human society. They are also influenced by man-made pollution easily. It is human beings that do great harm to the ocean ecosystems(生态系统).
The coral reefs(珊瑚礁)are fine ecosystems that provide food and protection for many ocean creatures. The coral in almost all of the oceans is in danger from pollution.Chemicals from factories end up in the seas and oceans and destroy coral reefs. If the coral systems die some ocean creatures will be sure to die out.
Protecting the ocean also has something to do with the protection of ocean wildlife like dolphins. The fishing industry depends on modern ways to catch many fish in order to earn more money. But the nets for fishing also seize other sea animals. The fishing boat workers are advised to check their nets and set other ocean animals free. But the boats are in a hurry to make money and often other ocean animals are caught with fish.
Offshore oil spills(近海石油泄露) can destroy the ocean environment because oil kills all ocean life. The world depends on oil and because there is a great amount of oil off the shore of many countries, the need for oil is more important than the risk of the oil spill. However, the fact is that one human mistake can lead to an ocean environmental accident that will cause years of damage to the fine ocean ecosystems. Oil spills will kill all the creatures in the area of the spill. The oil will be washed up on shore and destroy the ecosystems along the shore including birds.
Everyone who cares about the environment should be interested in protecting the ocean, and all of us should do something for the protection of the ocean.
【小题1】According to the passage, the ocean is harmed easily as a result of .
| A.the overuse of the oceans |
| B.the change of natural conditions |
| C.the increase of population by the sea |
| D.the increasing activities of humans |
| A.How ocean creatures depend on coral reefs. |
| B.Coral reefs are home to ocean animals. |
| C.The great harm caused by factory pollution. |
| D.The importance of protecting coral systems. |
| A.catch | B.attract | C.place | D.cover |
| A.Because they believe the oil spill can be stopped. |
| B.Because there is a large amount of oil in the sea. |
| C.Because they are in great need of oil. |
| D.Because getting oil in sea is easier than on land. |

I’m sure many of you have seen Star Wars, Jurassic Park, Multiplicity, or many of the other movies that describe cloning. Most of what you see in these movies is false. What you don’t know is that cloning could be dangerous, to the clone and to our society as a whole. I think human cloning is wrong mainly for four reasons.
What about identity? Humans are promised the right to their own personalities. What would happen if we ignore those rights by giving them someone else’s genetic identity? True, Cloning may prevent people from possessing their identities.
Also, these is a large power struggle here. Cloning means a degree of power and controls over another person’s physical identity and that ignores their rights and their only personalities. The person doing the cloning would have more power than any parent would have.
Cloning would also deal with killing embryos (胚胎). You might not have known, but Dolly, the sheep that was cloned in 1996, was one of over 200 sheep embryos and hers was the only embryo that survived. The rest died or were thrown away. Imagine if the failure rate was that high when we started to clone humans. cloning means running the risk of wasting too much effort
Cloning someone, at this present time, would be extremely dangerous to the birth mother and the clone. In studies done on cows, 4 out of 12 birth mothers died. There is a very high failure rate, which is shown in the cloning of Dolly. Even if you had a few good embryos, failures have been noticeable in animal tests.
So, should we work ahead in the world of cloning? I say no. the risks are greater than the benefits. It’s dangerous to the clone and to the birth mother. We would be killing human lives in the process. It would also be a violation(侵害) of the clone’s right to its own genetic identity and personality.
【小题1】The author thinks human cloning is wrong mainly for ______ reasons.
| A.4 | B.3 | C. 2 | D.5 |
| A.Cloning itself gives parents great power over identity. |
| B.People’s identity is completely determined by their genes. |
| C.Government has the rights to confirm people’s identities. |
| D.Cloning may prevent people from possessing their identities. |
| A.human cloning is much more difficult than animal cloning |
| B.there are 200 sheep successfully cloned. |
| C.cloning means running the risk of wasting too much effort |
| D.numbers of baby animals are likely to be created by cloning |
| A.To introduce the topic of the article. |
| B.To present his idea about the movies. |
| C.To state the conclusion first. |
| D.To make the article unusual. |
| A.What Is Human Cloning |
| B.Human Cloning Is Wrong |
