题型：不详难度：来源：
When 40 per cent of Hawaii"s US$14 million-a-year papaya (木瓜)industry was destroyed by a virus five years ago, work began on creating genetically engineered(转基因的) trees.
Researchers successfully introduced seeds that were designed to resist the virus. Since then, more and more people have been testing genetically engineered trees.
Some researchers put special bacteria into trees to help them grow faster and produce better wood. Others are trying to create trees that can clean polluted soil.
Meanwhile fruit farmers are looking for trees that are strong enough to resist worms, and paper companies want trees that produce more wood and therefore more paper.
The Pentagon (五角大楼) even gave the researchers US$500,000 this year after they developed a pine tree that changes its colours if it senses a chemical attack..
So far, the poplar, eucalyptus (杨树与桉树), apple and coffee trees are among those being engineered. All this can be done today because we have a better understanding of tree genomes(基因组).
However, some people fear that the genetically engineered trees will cause dangerous results. They are worried that the new trees will breed with natural species and change the balance of the forest environment.
"It could be destructive," said Jim Diamond, an environmentalist. "Trees are what is left of our natural environment and home to many endangered species."
But researchers insist that science could give nature a fighting chance against both natural and man-made dangers.
They hope to answer the critics by stopping the new trees from breeding, so their effect on the environment can be controlled.

| A．Trees that worms can"t hurt. |
| B．Trees that can protect themselves at a chemical attack. |
| C．Trees that can resist wind better. |
| D．Trees that can improve soil conditions. |
| A．They think science could give nature a fighting chance against both natural and man-made dangers. |

Speaking, of course, can"t go without listening. If you want to pronounce a word correctly, first you must hear it correctly. The sounds of the Chinese and English languages are not exactly the same. If you don"t listen carefully, you"ll find it difficult or even impossible to understand the native speakers.
Well, what about writing? Like speaking, it"s to exchange ideas. People generally use shorter words and shorter sentences in their writing. The important thing is to make your idea clear in your head and then to write it in clear lively language.
Chinese students read far too slowly. If you read fast, you understand better. If you read too slowly, by the time you have reached the end of a page you have forgotten what the beginning is about. When you meet with new words, don"t look them up in the dictionary. Guess the meaning from the context(上下文). You may not guess quite correctly the first time, but as new words come up again and again in different contexts, their meaning will become clearer and clearer. If you look up every word, you"ll never finish a book.
Students of a foreign language need a particular knowledge, the knowledge of the life, history and geography of the people whose language they are studying. They should study these subjects in the
foreign language, not only in translation. In this way one can kill two birds with one stone: learn a foreign language and get some knowledge of the foreign country at the same time.
小题1: In the first paragraph, the writer told us _________.
| A．how to speak English well |
| B．how to read and write English |
| C．why spoken English is very important |
| D．why English people couldn"t understand Lenin |
| A．to kill two birds with one stone |
| B．to learn two languages at a time |
| C．to study all the subjects in a foreign language |
| D．to get some knowledge of the foreign country as well as learn the language |
| A．how to imporve reading faster |
| B．how to guess the meaning from the context |
| C．how to look up new words in the dictionary |
| D．how to grasp the general meaning of a passage |
| A．to get some particular knowledge |
| B．to get more than what one pays |
| C．the stone is too big |
| D．the birds are blind enough |

Bonnie is traveling on the Orangutan Transit System, called the O-Line, at the National Zoo in Washington, D.C. The O-Line stretches from the Great Ape House, where Bonnie lives, to an exhibit called Think Tank. There she and other orangutans participate in a study trying to answer the questions: Do animals think? If so, how?
Think Tank scientists look for clues that an animal is thinking. A baby orangutan following its mother is probably not thinking. But an orangutan using a stick to reach honey in a beehive probably is thinking. It’s figuring out how to obtain a sweet treat.
To learn more about what the orangutans are thinking, Think Tank scientists are teaching orangutans a language of symbols. The apes don’t actually speak. They point to the symbols to show their thoughts.
Each symbol stands for a word. Different categories of the symbols have their own shapes. Food symbols, for example, are rectangles(矩形); object symbols are circles; and verbs are diamonds.
Computers help the orangutans learn the symbolic language. After the apes are shown an apple, for example, their task is to touch the apple symbol on a computer screen. They can do so. All six orangutans have learned a few symbols, but only Azy and Indah have learned eight symbols and can use the computer.
Azy and Indah choose to live at Think Tank. The others commute(往返) from the Great Ape House on the O-Line. All attend Think Tank sessions, though none are made to do so. “They’re eager to learn”, one of the scientists says. “They never turn me down!”
小题1:What is the main idea of the passage?
Scientists are doing research on whether animals can think and how they think.
Biologists have found that orangutans are more intelligent than other animals.
Orangutans at the National Zoo can be taught to communicate with humans easily.
Animals are being taught by scientists to speak to one another at the National Zoo.
小题2: The Orangutan Transit System refers to _____.
a way that can teach animals to learn things and communicate quickly
a place for various animals in the National Zoo to participate in the study
a walkway for the orangutans to travel to different sections of the zoo
a line for the orangutans to travel between the Great Ape House and the Think Tank
小题3: According to the passage, scientists use a system of symbols to help _____.
find out which orangutan can learn the symbolic language fast
attract all the orangutans to live together at Think Tank
communicate with the orangutans and understand them better
understand whether animals can learn a language and express themselves by using it
小题4: It can be inferred from the passage that _____.
a baby orangutan has his own intention though following his mother
many animals in the wild can learn symbolic languages to express their thoughts
the cleverer the animals are, the more knowledge they would like to learn
orangutans can form mental images in their minds when they see objects

A survey of 1000 people was carried out, which is organised by the National Centre of Language .The study suggested people in London were the most likely(78%) to have studied another language, Scots were next at 74%, followed by the northeast of England (71%).In the west of England, more than six in ten have knowledge of another language.
Barrie Hunt from OCR said, “People are often very negative about Britain，s grasp of foreign languages but in reality the number of people who can speak a second language is impressive. The great joke is that many of these people will have no formal qualification to show their family, friends and employers what they can do. Whether they are fluent or just able to hold a short conversation in another language is unknown.”
He said OCR had set a new language scheme called Asset Languages to encourage people of all ages to learn languages in bite-sized amounts and get a qualification.
The scheme also provides assessment for community languages spoken at home, such as Chinese, Urdu and Punjabi.
Isabella Moore from the National Centre of Languages said, “Employers want evidence of good communication skills, confidence and outward-looking attitudes, so a language qualification is an important addition to anyone，s resume.”
