What would you think if someone suggested knocking down St Paul’s Cathedral to widen the road? Or pulling down Big Ben to make way for a car park? It would be ridiculous, right? But when it comes to devastation (毁灭) of the natural world, we aren’t so easily shocked. But we should be…or we’ll be in a lot of trouble.
Nature is shrinking by the day. Ancient forests are destroyed. Wetlands are becoming dry. Woodland is disappearing, and all in the name of progress. This is bad in itself, but it’s devastating for biodiversity.
Biodiversity refers to the variety of plants, animals and other living things that are all interconnected. The ecological services provided by biodiversity are vital to everyday life. The air we breathe is a product of photosynthesis (光合作用) by green plants. Insects, worms and bacteria break down waste and make soils rich. And tiny organisms clean the water in rivers and sea. In fact, all life on the earth exists thanks to the benefits of biodiversity. More than 90 percent of the calories consumed by people worldwide are produced from 80 plant species. And 30 percent of medicines are developed from plants and animals. Maintaining a wide diversity of species in each ecosystem is necessary to preserve all living things.
The loss of biodiversity could be devastating. “It is wrong to think that biodiversity can be reduced indefinitely without threatening humans,” said Harvard University biologist Edward O. Wilson, known as the “father of biodiversity”. He warned, “We are about to reach a critical point beyond which biodiversity loss will become irreversible (不可挽回的).”
But what can we do? The present problem is that the concept of biodiversity is so vague (含糊的). People might care about giant pandas, but it is much harder to excite them about the fate of tiny sea creatures which are being boiled to death in the cooling systems of power stations along coastlines. The Guardian newspaper is trying to help. It has launched the Biodiversity 100 campaign to try to convince governments around the world to take action to deal with the widespread concerns about biodiversity. This includes persuading the UK government to create a series of marine reserves to reserve the decrease in the sea-life caused by industrial fishing, stopping fishing sharks by the Japanese fishermen and banning the killing of dingoes (wild dogs) in Australia, among many other things.
There is a lot to do. And we’d better act quickly if we don’t want to end up with a planet that can’t sustain life!The writer thinks it ________ to pull down Big Ben to make way for a car park.
| A．unreasonable | B．necessary | C．difficult | D．reasonable |

| A．nature is badly polluted by humans |
| B．species are becoming fewer and fewer day by day |
| C．rainforests are being cut down every day |
| D．nature is full of mysteries |
Edward O. Wilson thinks that ________.
| A．it doesn’t matter to reduce biodiversity |
| B．people have done enough to preserve biodiversity |
| C．the situation of biodiversity is very serious |
| D．biodiversity loss has become irreversible |
When it comes to biodiversity, the present problem is that ________.
| A．people might not clearly know what is biodiversity and what should be protected |
| B．people are not aware that giant pandas are endangered |
| C．people don’t realize that biodiversity is vital to everyday life |
| D．people hunt sea creatures for food |
What does the underlined word “It” in paragraph 5 refer to?
| A．The UK government. | B．The concept of biodiversity. |
| C．The action to deal with the problem. | D．The Guardian newspaper. |

Research has shown that two-thirds of human conversation is taken up not with discussion of the cultural or political problems of the day, not heated debates about films we've just watched or books we've just finished reading, but plain and simple ____.
Language is our greatest treasure as a species, and what do we ____ do with it? We gossip. About others' behaviour and private lives, such as who's doing what with whom, who's in and who's out-and why; how to deal with difficult ____ situations involving children, lovers, and colleagues.
So why are we keen on gossiping? Are we just natural ____, of both time and words? Or do we talk a lot about nothing in particular simply to avoid facing up to the really important issues of life? It's not the case according to Professor Robin Dunbar. In fact, in his latest book, Grooming, Gossip and the Evolution of Language, the psychologist says gossip is one of these really____issues.
Dunbar ____ the traditional view that language was developed by the men at the early stage of social development in order to organize their manly hunting activities more effectively, or even to promote the exchange of poetic stories about their origins and the supernatural. Instead he suggests that language evolved among women. We don't spend two-thirds of our time gossiping just because we can talk, argues Dunbar—____, he goes on to say, language evolved specifically to allow us to gossip.
Dunbar arrived at his cheery theory by studying the ____ of the higher primates（灵长类动物）like monkeys. By means of grooming--cleaning the fur by brushing it, monkeys form groups with other individuals on whom they can rely for support in the event of some kind of conflict within the group or____ from outside it.
As we human beings evolve from a particular branch of the primate family, Dunbar ____ that at one time in our history we did much the same. Grouping together made sense because the bigger the group, the greater the ____ it provided; on the other hand, the bigger the group, the greater the stresses of living close to others. Grooming helped to ____ the pressure and calm everybody down.
But as the groups got bigger and bigger, the amount of time spent in grooming activities also had to be ____ to maintain its effectiveness. Clearly, a more ____ kind of grooming was needed, and thus language evolved as a kind of vocal（有声的）grooming which allowed humans to develop relationship with ever-larger groups by exchanging information over a wider network of individuals than would be possible by one-to-one ____ contact.
A．claim B．description C．gossip D．language
A．occasionally B．habitually C．independently D．originally
A．social B．political C．historical D．cultural
A．admirers B．masters C．users D．wasters
A．vital B．sensitive C．ideal D．difficult
A．confirms B．rejects C．outlines D．broadens
A．for instance B．in addition C．on the contrary D．as a result
A．motivation B．appearance C．emotion D．behaviour
A．attack B．contact C．inspection D．assistance
A．recalls B．denies C．concludes D．confesses
A．prospect B．responsibility C．leadership D．protection
A．measure B．show C．maintain D．ease
A．saved B．extended C．consumed D．gained
A．common B．efficient C．scientific D．Thoughtful
A．indirect B．daily C．physical D．secret

We realize that if rivers are polluted with waste products from factories, we will die.___46_____, in most countries wastes are ___47______put into rivers or into the sea, and there are _48_____laws to stop this.
We know, too, that if the___49____ of the world continues to rise at the present rate, in a few years, there will not be enough___50_____. What can we do to solve these problems ?
It we eat more vegetables and less___51____, there will be more food available for everyone. Land that is used to grow crops __52_____five times more people than land where animals are kept.
Our natural resources will _53_____longer if we learn to recycle them. The world population will not rise so quickly if people use modern methods of birth__54_______ .

Many theories regarding the causes of juvenile delinquency（crimes committed by young people）focus either on the individual or on society as the major contributing influence．Theorieson the individual suggest that childrencriminal behavior before they were not sufficientlyfor previous misbehaviors or that they have learned criminal behavior through interaction with others．Theories focusing on the role of society suggest that children commit crimes into their failure to rise above their socioeconomic status or as a rejection of middle-class values.
Most theories of juvenile delinquency have focused on children fromfamilies，the fact that children from wealthy homes also commit crimes．The latter may commit crimes for lack of adequate control from parents．All，however，are uncertain or unimproved and are of course challenged with criticism.
Changes in the social structure may indirectlyjuvenile crime rates．For example，changes in the economy thatto fewer job opportunities for youth and rising unemployment make gainful employment increasingly difficult to obtain．This results inamong youths and may inlead more youths into criminal behavior.
Families have also experiencedthese years．More families consist of one parent households or two working parents；，children are likely to have less supervision at home than was common in the traditional family．This lack of parental supervision is thought to be an influence on juvenile crime rates．Other noticeableof offensive acts includeexperience or failure in school，theavailability of drugs and alcohol，and the growing phenomenon of child abuse and child neglect．All these conditions tend to increase theof a child committing a criminal act，a direct cause and effect relationship has not yet been established.

Have you ever seen a movie in which a building was burned down or a bridge was destroyed? Have you seen films in which two trains crashed or a ship into the ocean? If , you may have wondered how these things could happen without the actors and actresses in the film.
The man who knows the is the “special-effects” man. He has one of the most important in the film industry. He may be ordered to a flood or to make a battlefield explode. But he may also be told to create a effect which is much less exciting, just as important to the success of the film.
In a for one movie there was a big glass bowl filled with water in which small fish were swimming. The director of the movie the fish to stop swimming suddenly they seemed to stare at (盯着看) an actor. Then the director wanted the fish to staring and swim. But fish can’t be ordered to do anything. It was quite a .

The massive magnitude（震级） 8.8 earthquake that struck the west coast of Chile moved the entire city of Concepcion at least 10 feet to the west, and moved other parts of South America as far apart as the Falkland Islands and Fortaleza, Brazil.
These measurements, produced from data gathered by researchers from four universities and several agencies, paint a much clearer picture of the power behind this earthquake, believed to be the fifth-most-powerful since instruments have been available to measure earthquake.
Buenos Aires, the capital of Argentina moved about 1 inch to the west. And Chile's capital, Santiago, moved about 11 inches to the west-southwest. The cities of Valparaiso and Mendoza, Argentina, northeast of Concepcion, also moved.
The quake's epicenter (震中) was in a region of South America that's part of the so-called “ring of fire,” an area of major seismic（地震的） stresses which encircles（环绕，包围） the Pacific Ocean. All along this line, the plates on which the continents move press against each other.
Mike Bevis, professor of earth sciences at Ohio State, has led a project since 1993 that has been measuring crustal（地壳的）movement in the Central and Southern Andes. The effort is called the Central and Southern Andes GPS Project, or CAP.
Ben Brooks, an associate researcher with the School of Ocean and Earth Science and Technology at the University of Hawaii, said that the event, offers a unique opportunity to better understand the seismic processes that control earthquakes.
“We now have modern, precise instruments to evaluate this event, and because the site borders a continent, we will be able to get evidences of the changes it caused.” said Brooks.
