Running like the wind, roaring like thunder, tigers have long been feared and respected as a king of the animal world．But last week a report said that there are no more than 30 wild tigers left in south China．
This was the conclusion of a team of scientists from China"s State Forestry Administration and the World Nature Fund．
The South China tiger, also known as the Chinese tiger, is native to southern China．In the 1950"s, there were over 4000 tigers found in mountain forests in the country．But due to the destruction of their natural habitat and uncontrolled hunting, it has been pushed on to the list of the world"s top ten most endangered species．
Sixty-six of the big cats can be found in the cages of a dozen zoos around China．But they are nothing like their wild cousins．They have lost their natural skills such as hunting and killing．If they were set free they could not look after themselves．
"Breeding has damaged the quality of the species", said Pei Enle, deputy director of the Shanghai Zoo．
To reintroduce the species into the wild, the country started a programme to send five to ten young tigers to South Africa．Four of them have already arrived．Progress has been made as two elder tigers have recovered some of their instincts（本能）and can hunt wild animals by themselves at the African base．
" South Africans are very experienced in reintroducing big animals to the wild．The country has very good natural conditions for the tigers to learn in", said Lu Jun, office director of the National Wildlife Research and Development Center．" We tried in Fujian Province, but it was not successful as there was not a complete eco-chain（生物链） and there was a lack of space．"
The tigers should return to China in 2007 when the reservations in Fujian are ready．
1．What is the main reason for the South China tiger becoming one of the world"s top ten most endangered species?
A．Because it has lost its n

atural instincts． B．Because there is not a complete eco-chain．
C．Because there is no space for it． D．Because uncontrolled hunting has destroyed its natural living conditions．
2．How is the programme of sending several tigers to South Africa getting on?
A．Its effect still remains to be seen．
B．Two tigers can already compete with their wild cousins．
C．Some of the tigers are already on the road to recovering their natural skills．
D．The tigers should be able to recover their instincts completely by 2007．
3．By saying " but they are nothing like their wild cousins", the writer means that ______．
A．they are no longer feared by other wild animals
B．they don"t know how to hunt or kill
C．a complete change has resulted in the species because of breeding
D．to reintroduce them into the wild has become an urgent task
4．What is the purpose of sending young tigers to South Africa?
A．To help the tigers recover their ability to live in the wild．
B．To provide them with a better environment．
C．To get the tigers to go on a tour．
D．To find a complete eco-chain for them．
5．Which one is not the reason for South Africa being chosen as the training place?
A．Because the tigers can hunt wild animals by themselves at the African base．
B．Because South Africans are skilled at dealing with the tigers．
C．Because there is a complete eco-chain and enough space there．
D．Because the country has good natural conditions for the tigers to learn in．

What will we be eating in the future? Here are the top factors that will be affecting the food that ends up on our tables in the new century.
Genetically engineered food Many crops are already genetically engineered, often to produce more food, fight against pests or improve nutrition. But concern is growing over the lasting effects of changing nature. While existing research has found little harm in genetic engineering, a recent study found the flower powder of a genetically engin

eered corn can kill the normal butterfly. This finding made many people nervous and brought attention to the topic.
Dining out Americans are increasingly eating meals away from home, both in sit-down restaurants and in fast food outlets. In the last decade alone there was a 14 percent decrease in the number of meals eaten at home. At the same time, restaurants are just beginning to really open their doors on the Internet. Websites exist to make restaurant reservations (预约), view menus, and get tips from your favorite chefs. The dining out trend and the demand for high-quality, chef-prepared food have encouraged chefs to spend time out of the kitchen — teaching classes, appearing on TV, and writing cookbooks.
Eating in Eating in doesn’t always mean cooking. Ready-made meals and froz

en food sold in supermarkets taste better all the time. Restaurants are offering neatly packaged “food to go”, and meals can be ordered over the Internet. Cooking is not as much as a necessity, as it is a hobby or a special treat.
Agriculture Although American farmers have been hit hard recently by bad weather, low prices and decreasing government help, they can increase grain production not using old farming methods.

The word “conservation” has a thrifty meaning. To conserve is to save and protect, to leave what we ourselves enjoy in such a good condition that others may also share the enjoyment. Our forefathers had no idea that human population would increase faster than the supplies of raw materials: most of them, even until very recently, had the foolish idea that the treasures were “limitless” and could “last forever”. Most of the citizens of earlier generations knew little or nothing about the complicated and delicate system that runs all through nature, and which means that, as in a living body, an unhealthy condition of one part will sooner or later be harmful to all the others.
　　Fifty years ago, nature study was not part of the school work; scientific forestry was a new idea; wood was still cheap because it could be brought in any quantity from distant woodlands; soil destruction and river floods were not national problems; nobody had yet studied long-term climatic cycles in relation to proper land use; even the word “conservation” had nothing of the meaning that it has for us today.
　　For the sake of ourselves and those who will come after us, we must now set about correcting the mistakes of our forefathers. Conservation should be made part of everybody’s daily life. To know about the water table in ground is just as important to us as a knowledge of the basic math formulas. We need to know why all watersheds (上游集水区) need the protection of plant life and why the running current of streams and rivers must be made to give their full benefit to the soi

l before they finally escape to the sea. We need to be taught the duty of planting trees as well as of cutting them. We need to know the importance of big, grown trees, because living space for most of man’s fellow creatures on this planet is figured not only in square measure of surface but also in cubic (立方体的) volume above the earth. In a word, it should be our goal to restore as much of the original beauty of nature as we can.
小题1:The author’s attitude towards the use of natural resources is _________.

A．positive

B．uninterested

C．optimistic

D．critical

小题2:According to the author, the greatest mistake of our forefathers was that _________.

A．they had no idea about scientific forestry

B．they had little or no sense of environmental protection

C．they were not aware of the importance of nature study

D．they had no idea of how to make good use of raw materials

小题3:To avoid repeating the mistakes of our forefathers, the author suggests that _________.

A．we plant more trees

B．natural sciences be taught to everybody

C．environmental education be directed toward everyone

D．we return to nature

小题4:How can you understand the underlined sentence in the last paragraph?

A．Our living space on the earth is getting smaller and smaller.

B．Our living space should be measured in cubic volume.

C．We need to take some measures to protect space.

D．We must preserve good living conditions for both birds and animals.

Three years ago I listened to a lecture on cognition (认知) that changed the way I think about intelligence. There are two types of cognition. The first is normal cognition: the ability to regain knowledge from memory. The second type of cognition is metacognition: the ability to know whether or not you know.
Does this affect intelligence? In traditional education, intelligence is measured by cognitive ability. Some people can easily produce everything they know on a test. But others are awarded with poor grades and considered inferior. But does this inability make them any less intelligent? If the question came up on a task, they could refer to a book or a quick Google search. In reality they’re just as effective as the people that ace a test. They just can’t prove it as easily.
Metacognition is more important to success than cognition. A person with poor cognitive ability, but great metacognitive ability might do poorly in school, but when faced with a challenge, they understand their abilities and take the best course of action. For example, when faced with a question, a person with strong metacognitive

ability will deal with it like this. If he knows the answer, but can’t come up with it, he can always do a bit of research. If he knows for sure that he doesn’t know, then he can start educating himself. Because he’s aware of his ignorance, he doesn’t act with foolish confidence. These people might not seem intelligent at first glance, but because they know what they know, they make better decisions and learn the most important things.
However, people with great cognitive ability but poor metacognitive ability may be considered excellent at a young age for acing every test and getting great SAT scores. Unfortunately, they’ve been ruined by poor metacognition: they think they know everything but they really don’t. They are overconfident, fail to learn from mistakes, and don’t understand the slight differences of personal relationships, showing disregard for persons with lower cognitive ability. They may make the worst decisions.
The most important mental power is the ability to know what you don’t know. The recognition of a fault is the first step to improvement. Don’t try to hide a lack of knowledge. For intelligent people this is the toughest lesson to learn.
小题1:People with great cognitive ability tend to _________.

A．do well in tests	B．be considered inferior
C．be more effective than others	D．do research when faced with a task

小题2:The underlined phrase “take the best course of action” probably means _________.

A．starting educating himself	B．taking action during the course
C．making the right decision	D．coming up with many ideas

小题3:People with poor metacognition may not succeed because they_________.

A．lack basic moral values	B．have improper self-evaluation
C．fail to communicate with others	D．show little respect for others

小题4:The author probably supports the idea that _________.

A．intelligence is measured by cognitive ability

B．cognition is the most important mental power

C．the toughest lesson is to distinguish the two types of cognition

D．the awareness of one’s ignorance contributes to one’s improvement
