回答题

Extinction is difficult concept to grasp．It is an（26）concept．It&39;s not at all like the killing of individual lifeforms that can be renewedthrough normal processes of reproduction．Nor is it simply （27）numbers．Nor is it damage that can somehow be remedied or for which some substitute can be ound．Nor is it something that simply affects our own generation．Nor is it something that could be remedied by some supernatural power．It is rather an（28）and final act for which there is no remedy

on earth or in heaven．A species once extinct is gone forever．However many generations（29）us in coming centuries, none of them will ever see this species that we extinguish．Not only are we bringing about the extinction of life（30）, we are also making the land and the air and the sea so toxic that the very conditions of life are being destroyed．（31）basic natural resources, not only are the nonrenewable resources being（32）in a frenzy (疯狂) of processing,consuming, and（33）, but we are also mining much of our renewable resources, such as the very soil itself on which terrestrial (地球上的) life depends．

The change that is taking place on the earth and in our minds is one of the greatest changes ever to take place in human affairs, perhaps the greatest, since what we are talking about is not simply another historical change or cultural（34）, but a change of geological and biological as well as psychological order of（35）

根据以下材料，回答题

Older Volcanic Eruptions

Volcanoes were more destructive in ancient history， not because they were bigger， but because the carbon dioxide they released wiped out life with greater ease.

Paul Wignall from the University of Leeds was investigating the link between volcanic eruptions and mass extinctions. Not all volcanic eruptions killed off large numbers of animals， but all the mass extinctions over the past 300 million years coincided with huge formations of volcanic rock. To his surprise， the older the massive volcanic eruptions were， the more damage they seemed to do. He calculated the "killing efficiency" for these volcanoes by comparing the proportion of life they killed off with the volume of lava that they produced. He found that for size， older eruptions were at least 10 times as effective at wiping out life as their more recent rivals.

The Permian extinction， for example， which happened 250 million years ago， is marked by floods of volcanic rock in Siberia that cover an area roughly the size of western Europe. Those volcanoes are thought to have pumped out about 10 gigatones of carbon as carbon dioxide. The global warming that followed wiped out 80 percent of all marine genera at the time， and it took 5 million years for the planet to recover. Yet 60 million years ago， there was another huge amount of volcanic activity and global warming but no mass extinction. Some animals did disappear but things returned to normal within ten thousands of years. "The most recent ones hardly have an effect at all，" Wignall says. He ignored the extinction which wiped out the dinosaurs 65 million years ago， because many scientists believe it was primarily caused by the impact of an asteroid. He thinks that older volcanoes had more killing power because more recent life forms were better adapted to dealing with increased levels of CO2.

Vincent Courtillot， director of the Paris Geophysical Institute in France， says that Wignall"s idea is provocative. But he says it is incredibly hard to do these sorts of calculations. He points out that the killing power of volcanic eruptions depends on how long they lasted. And it is impossible to tell whether the huge blasts lasted for thousands or millions of years. He also adds that it is difficult to estimate how much lava prehistoric volcanoes produced， and that lava volume may not necessarily correspond to carbon dioxide emissions.

Why did older volcanic eruptions do more damage than more recent ones？查看材料

A.Because they killed off life more easily.

B.Because they were brighter.

C.Because they were larger.

D.Because they were hotter.

根据以下内容回答题：

Homing pigeons are placed in a training program from about the time they are twenty。Eight days of age．They are taught to enter the lon through a trap and to exercise above and around the loft．and graduaUy they are taken away for short distances in wicker baskets and released．They are then expected to find their way home in the shortest possible time． In their training flights or in actual races，the birds are taken to prearranged distant point sand released to find their way back to their own logs．Once the birds are liberated，their owners，who are standing by at the home lofts，anxiously watch the sky for the return of their entries．Since time is of the essence，the speed with which the birds can be induced to enter the loft trap may make the difference between gaining a win or a second place． The head of a homing pigeon is comparatively small，but its brain is one quarter large than that of the ordinary pigeon．The homing pigeon is very intelligent and will persevere to the point of stubbornness；some have been known to fly a hundred miles off course to avoid a storm． Some homing pigeon experts claim that this bird is gifted with a form. of built-in radar that helps it find its own loft ager hours of flight，for hidden under the head feathers are two very sensitive ears，while the sharp，prominent eyes can see great distances in daytime． Why do homing pigeons fly homeg They are not unique in this inherent skill；it is found in most migratory birds，in bees，ants，toads，and even turtles，which have been known to travel hundreds of miles to return to their homes．But in the animal world，the homing pigeon can be trusted with its freedom and trained to carry out the missions that people demand．

What is the purpose of the passage？

A.To convince the reader to buy a homing pigeon．

B.To inform. the reader about homing pigeons and their training

C.To protect homing pigeons against the threat of extinction（绝迹）．

D.To encourage the owners of homing pigeons to set the birds free．

回答题

"Family" is of course an elastic word．And in different countries it has different meanings．Butwhen British people say that their society is based on family life, they are thinking of "family" in itsnarrow, peculiarly European sense of mother, father and children living together in their own houseas an economic and social unit．Thus, every British marriage indicates the beginning of a new andindependent family--hence the tremendous importance of marriage in British life．For both man andwoman, marriage means leaving one&39; s parents and starting one&39; s own life．The man&39; s first dutywill then be to his wife, and the wife&39; s to her husband．He will be entirely responsible for her finan-cial support, and she for the running of the new home．Their children will be their common responsi-bility and their alone．Neither the wife&39; s parents nor the husband&39; s, nor their brothers or sisters,aunts or uncles, have any right to interfere with them--they are their own masters．

Readers of novels like Jane Austen&39; s Pride and Prejudice will know that in former times, mar-riage among wealthy families were arranged by the girl&39; s parents, that is, it was the parents&39; duty tofind a suitable husband for their daughter, preferably a rich one, and by skillful encouragement tolead him eventually to ask their permission to marry her．Until that time, the girl was protected andmaintained in the parents&39; home, and the fmancial relief of getting rid of her could be seen in theirgiving the newly married pair a sum of money called a dowry(嫁妆)．It is very different today．

Most girls of today get a job when they leave school and become financially independent before theirmarriage．This has had two results．A girl chooses her own husband, and she gets no dowry．Everycoin has two sides; independence for girls is no exception．But it may be a good thing for all of thegirls, as their social status are much higher and they are no longer the subordinate(部下，下级) oftheir parents and husbands．

What does the author mean by "Family is of course an elastic word"？查看材料

A.Different families have different ways of life．

B.Different definitions could be given to the word．

C.Different nations have different families．

D.Different times produce different families．

What Makes a Soccer Player Great？

Soccer is played by millions of people all over the world， but there have only been few players who were truly great. How did these players get that way was it through training and practice， or are great players "born， not made" ？ First. these players came from places that have had famous stars in the past players that a young boy can look up to and try to imitate. In the history of soccer， only six Countries have ever won the World Cup three from South America and three from western Europe. There has never been a great national team or a really great player——from North America or from Asia. Second. these players have all had years of practice in the game.

Alfredo Di Stefano was the son of a soccer player， as was Pele. Most players begin playing the game at the age of three or four.

Finally. many great players come from the same kind of neighborhood a poor， crowded area where a boy"s dream is not to be a doctor， lawyer， or businessman， but to become a rich， famous athlete or entertainer. For example， Liverpool. which produced the Beetles， had one of the bestEnglish soccer teams in recent years. Pele practiced in the street with a "ball" made of rags. AndGeorge Best learned the tricks that made him famous by bouncing the ball off a wall in the slumsof Belfast.

All great players have a lot in common， but that doesn"t explain why they are great.

Hundreds of boys played in those Brazilian streets， but only one became Pele. The greatest play-ers are born with some unique quality that sets them apart from all the others.

According to the author， which of the following statements is true？查看材料

A.Great soccer players are born， not made.
