Running like the wind, roaring (咆哮) 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.
Sixtysix 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 ecochain(生物鏈) and there was a lack of space.”
The tigers should return to China in 2007 when the reservations in Fujian are ready.
【小題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 natural instincts. |
B.Because there is not a complete ecochain. |
C.Because there is no space for it. |
D.Because uncontrolled hunting has destroyed its natural living conditions. |
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. |
A.they are no longer feared by other wild animals |
B.they don't know how to hunt or kill |
C.a(chǎn) complete change has resulted in the species because of breeding |
D.to reintroduce them into the wild has become an urgent task |
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 ecochain for them. |
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 ecochain and enough space there. |
D.Because the country has good natural conditions for the tigers to learn in. |

The world itself is becoming much smaller by using modern traffic and modern communication means. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it.
Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in one place, man moved to another place. But this is no longer true.
Man is now slowly polluting the whole world.
Air pollution is still the most serious. It’s bad for all living things in the world, but it is not the only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily.
Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city, and from putting dirty smoke into the air. Pollution by SO2 is now the most dangerous kind of air pollution. It is caused by heavy traffic. We are sure that if there are fewer people driving, there will be less air pollution.
The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must take care of the rise in pollution at the same time.
【小題1】 _________, our world is becoming much smaller.
A.Because of the rise in pollution |
B.Thanks to science development |
C.Because the earth is being polluted day and night |
D.Because the earth is blown away by the wind every year |
A.much easier than | B.a(chǎn)s easy as |
C.much harder than | D.a(chǎn)s hard as |
A.rubbish | B.noise pollution |
C.a(chǎn)ir pollution | D.water pollution |
A.it makes much noise |
B.it makes us angry more easily |
C.it makes our rivers and lakes dirty |
D.it’s bad for all living things in the world |
A.Many countries are making rules to fight pollution. |
B.The pollution of the earth grows as fast as the world population does. |
C.The problem of pollution is not so serious because there are not so many people on the earth. |
D.If people could go to work by bus or bike instead of car or motorbike, it would be helpful in fighting against the problem of SO2. |

The first robot rover to land on the Moon in nearly 40 years, China's Jade Rabbit, has begun sending back photos, with shots of its lunar lander(登月飛行器). Jade Rabbit rolled down a ramp lowered by the lander and on to the volcanic plain known as Sinus Iridum at 04:35 Beijing time on Saturday (20:35 GMT).It moved to a spot a few metres away, its historic short journey recorded by the lander. On Sunday evening the two machines began photographing each other. A Chinese flag is clearly visible on the Jade Rabbit as it stands deployed on the Moon's surface.
Ma Xingrui, chief mander of China's lunar programme, declared the mission (任務(wù))a “plete success”. The first soft landing on the Moon since 1976 is the latest step in China's ambitious space programme, says BBC science reporter Paul Rincon.
The lander will operate there for a year, while the rover is expected to work for some three months. The Chang'e3 mission landed some 12 days after being launched atop a Chinesedeveloped Long March 3B rocket from Xichang in the country's south. The official Xinhua news service reported that the lander began its descent(下降)on Saturday just after 13:00 GMT, touching down in Sinus Iridum (the Bay of Rainbows) 11 minutes later. “I was lucky enough to see a prototype rover(原型月球車(chē)) in Shanghai a few years ago it's a wonderful technological achievement to have landed,” Prof Andrew Coates, from UCL's Mullard Space Science Laboratory, told BBC News.
Chang'e3 is the third unmanned rover mission to touch down on the lunar surface, and the first to go there in more than 40 years. The last was an 840kg (1,900lb) Soviet vehicle known as Lunokhod2, which was kept warm by polonium(釙)210. But the sixwheeled Chinese vehicle carries a more sophisticated payload(復(fù)雜的有效負(fù)荷), including groundpenetrating radar which will gather measurements of the lunar soil and crust.
【小題1】What does the text mainly talk about?
A.China's space and aeronautics industry develops quickly. |
B.The importance of China's space and aeronautics industry. |
C.China's Jade Rabbit Moon rover sends back first photos. |
D.Chang'e3 is the third unmanned rover mission to touch down on the lunar surface. |
A.nearly 40 | B.37 |
C.64 | D.more than 40 |
A.do some research about the moon |
B.be the first settler on the moon |
C.to plant the Chinese flag onto the moon |
D.send a lovely jade rabbit onto the moon |
A.13:00 | B.20:00 |

The biggest danger facing airlines nowadays may not be a terrorist with a gun, but the man with portable computer in business class. In the last 16 years, pilots have reported well over 100 incidents that could have been caused by electromagnetic interference (電磁干擾). The source of this interference remains not proved, but increasingly, experts are pointing the blame at portable electronic devices such as portable computers, radio and cassette players and mobile telephones.
RTC.A. an organization which advises the aviation (航空 )industry, has suggested that all airlines ban such devices from being used during "critical" stages of flight particularly take- off and landing. Some experts have gone further, calling for a total ban during all flights .Cur- rently , rules on using these devices are left up to individual airlines. And although some air- lines prevent passengers from using such equipment during take-off and landing, most are un- willing to carry out a total ban, given that many passengers want to work during flight.
The difficulty is predicting how electromagnetic fields might affect an aircraft's computers. Experts know that portable devices send out radiation which affects those wavelengths which aircraft use for navigation and communication. But, because they have not been able to reproduce these effects in a laboratory. they have no way of knowing whether the interference might be. dangerous or not.
The fact that aircraft may be fragile to interference raises the risk that terrorists may use radio systems in order to damage navigation equipment. As worrying, though, is the passenger who can 't hear the instructions to turn off his radio because the music's too loud.
【小題1】What is said about the over 100 aircraft incidents in the past 16 years?
A.They may have been caused by the damage to-the radio systems. |
B.They may have taken place during take-off and landing. |
C.They were proved to have been caused by the passengers portable computers. |
D.They were suspected to have resulted from electromagnetic interference. |
A.Because it is extremely dangerous to conduct such research on an airplane. |
B.Because it remains a mystery what wavelengths are liable to be interfered with. |
C.Because research scientists have not been able to produce the same effects in labs. |
D.Because experts lack adequate equipment to do such research. |
A.they don't believe there is such a danger as radio interference |
B.the harmful effect of electromagnetic interference is yet to be proved |
C.most passengers refused to take a plane ,which bans the use of radio and cassette players |
D.they have other effective safety measures to fall back on |
A.a(chǎn) new rule for all airlines |
B.the disadvantages of electronic devices |
C.a(chǎn) possible cause of aircraft incidents |
D.effective safety measures for air flight |

No one wants to be tested. We would all like to get a driver’s license without answering questionsabout rights of way or showing that we can parallel park a car. Many future lawyers and doctors probablywish they could join their profession without taking an exam.
But tests and standards are a necessary fact of life. They protect us from unskilled drivers, harmful products and dishonest professionals. In schools too exams play a. constructive role. They tell public officials whether new school programs are making a difference and where new investments are likely to pay off.
They tell teachers what their students have learned--and have not. They tell parents how their children are doing compared with others their age. They encourage students to make more effort.
It is important to recall that for most of century, educators used intelligence tests to decide whichchildren should get a high-quality education. The point of IQ testing was to find out how much children were capable of learning rather than to test what they had actually learned. Based on IQ scores, millions of children
were assigned to dumbed-down programs instead of solid courses in science, math, history, literature andforeign language.
This history reminds us that tests should be used to improve education. Every child should have access to a high-quality education. Students should have full opportunity to learn what will be tested; otherwise theirscores will merely reflect whether they come from an educated family.
In the past few years, we have seen the enormous benefits that flow to disadvantaged students because of the information provided by state tests. Those who fall behind are now getting extra instruction inafter-school classes and summer programs. In their efforts to improve student performance, states are
increasing teachers salaries, testing new teachers and insisting on better teacher education.
Performance in education means the mastery of both knowledge and skills. This is why it is reasonable totest teachers to make sure they know their subject matter, as well as how to teach it to young children. And this is why it is reasonable to assess whether students are ready to advance to the next grade or graduate
from high school.
【小題1】According to the passage, school exams enable ______.
A.governments to make right policieshave made efforts |
B.students to meet their teachers' requirements |
C.teachers to understand if their students |
D.parents to compare their kids' behavior across schools |
A.lead to high-quality education |
B.a(chǎn)re less academically challenging |
C.a(chǎn)re intended for intelligent students |
D.enable children to make steady progress |
A.Disadvantaged students can benefit from state tests. |
B.Tests should focus on what students have actually learned. |
C.Intelligent tests decide if children should get a high - quality education. |
D.Intelligent tests are helpful in separating excellent students from poor ones. |
A.To re-assess the value of IQ testing. |
B.To defend the role of testing in education. |
C.To explain what high-quality education means. |
D.To call for thorough and complete reform in education. |

Humans might be the most highly-evolved species on the planet, but most animals possess skills we can only dream of having. Imagine how much electricity we could save if we could see in the dark the way cats do. Imagine leaping from tree to tree like a monkey. Giraffes, which are otherwise calm and good-natured, sleep only 4.6 hours a day.
We realized a long, long time ago that nature provides the best blueprint for invention. We’ve borrowed canals from beavers and reflectors from cat’s eyes. Although the words “bionics”(仿生學(xué)) became popular only after the 1960s, history shows that nature has always provided ideas on solving everyday problems. Our archives(檔案) don’t go back to the time of Leonardo da Vinci and his bird-like flying machines, but we can take you to the late 19th century, where we applied those same principles for building our first practical airplanes.
To prepare for their flight at Kitty Hawk, the Wright brothers studied the movements of pigeons to figure out how they stayed high up when they were heavier than air. Their success inspired scores of successors to improve on the airplane by studying various aspects of nature. One of Orville Wright’s pupils caught and stuffed seagulls to examine their wingspan. Meanwhile, two French inventors examined spinning sycamore(梧桐) seeds in an effort to apply those same motions, reversed, to a helicopter .
Some examples are more obvious than others. The outside of the airplane designed by the Wright brothers looks like a minimalistic(簡(jiǎn)單抽象藝術(shù)) structure. On the other hand, Barney Connett’s fish submarine actually looks like a fish.
Some bio-inspired concepts have yet to be invented. In the 1960s, the US Army commissioned several university professors to conduct research on the motor skills animals in hope of applying those same abilities to tanks. Tanks that run like horses or jump like grasshoppers(螞蚱)-sounds shocking, doesn’t it? But imagine how life would change if we could achieve that.
【小題1】“Cats”, “monkeys” and “giraffes” mentioned in paragraph 1 are examples to show______.
A.they are highly-evolved species as humans |
B.a(chǎn)nimals have skills that humans do not possess |
C.humans can learn animals’ skills |
D.they are skillful in different ways |
A.People carried out a systematic study on pigeons. |
B.People studied more animals and plants to develop the airplane. |
C.People could fly their airplane for fun. |
D.People kept their airplane at a French gallery. |
A.It has cost a large sum of money. |
B.It has changed our life. |
C.It has improved the abilities of tanks |
D.It has not succeeded yet. |
A.many inventions get ideas from nature. |
B.Some animals possess unique skills. |
C.People should protect nature. |
D.Bionics is far from perfect |

Want to travel as cheaply as possible while enjoying the great scenery as much as you like?
Backpacking is the way. As the most popular traveling choice among young western people, backpacking allows you to travel at your own free will. Carrying a tent, sleeping bag and clothes, backpackers also need to pack an attitude that will help them deal with many mental and physical challenges.
It is a thrill to put our ability to test and challenge ourselves with sorts of difficulties we might come across. So, backpacking is something young people can hardly deny.
Young people in Europe often travel around by train. Now, with plane tickets dropping in price, more are traveling to distant countries, such as Australia and China. And some just travel within their own countries.
But no matter where a backpacker travels, planning in advance is important if he or she wants to enjoy the trip.
Clothing
In summer, light, waterproof clothes are best. Backpackers must remember to travel lightly and not pack too many clothes.
Medicine
There are many medicines, especially for summer, such as those for sunstroke, snake bites and mosquitoes. Others are useful in every season, such as those for common colds, poisoning and diarrhea.
Cards
Three types of cards are of great value for backpacks: student Identity Card, personal ID and a credit card.
A student ID card can be helpful for saving money. It often gets train tickets and entrance tickets for cheaper prices in many Western countries.
Personal ID card can, not only get you out of trouble with local police, but also prove useful in all sorts of other situations.
Carrying a credit card can be a safe way of carrying money, as cash can easily get lost, stolen or wet.
And of course, don’t forget to enjoy your trip!

Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger, but we also affect our water supply in less obvious ways. You may wonder how paving(鋪砌) a road can lead to less usable fresh water. A major part of the water we use every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave, the less water can flow into the ground to become groundwater.
Human activity is not responsible for all water shortages(短缺). Drier climates are of course more likely to have droughts(干旱) than areas with more rainfall, but in any case, good management can help to make sure there is enough water to meet our basic needs.
Thinking about the way we use water every day can make a big difference, too. In the United States, a family of four can use 1.5tons of water a day! This shows how much we depend on water to live, but there's a lot we can do to lower the number.
You can take steps to save water in your home. To start with, use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher only when it is full. Help your parents fix any leaks (泄露、漏洞)in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.
【小題1】Which of the following is most likely to lead to less groundwater?
A.Using river water. | B.Throwing batteries away. |
C.paving parking lots. | D.Throwing rubbish into lakes. |
A.water on the ground | B.water from a well(井) |
C.water from the deep earth | D.water from lakes or rivers |
A.All water shortages are because of human behavior. |
B.It takes a lot of efforts to meet our water needs. |
C.There is much we can do to reduce family size. |
D.The average family in America makes proper use of water. |
A.show us how to fix leaks at home |
B.tell us how to run a dishwasher |
C.prove what drinking glass is best for us |
D.suggest what we do to save water at home |
A.why paving roads reduces our water. |
B.how much we depend on water to live. |
C.why droughts occur more in dry climates. |
D.how human activity affects our water supply. |

Why Doesn’t Anybody Copy Apple?
Apple’s products are the envy of the world. They have been spectacularly successful and are widely imitated, if not copied. The minute Apple crystallizes a product, everyone knows how to compete.This idea that the basis of competition is set by Apple and then the race is on to climb the path of improvement is unquestionable.When Apple releases a product that defines a category or dramatically changes the structure of an industry, it becomes obvious what needs to be built. But what I wonder is why everyone wants to copy Apple’s products but nobody wants to copy being Apple?
I can think of two reasons. Firstly, Apple is not worth copying because it's not successful; secondly, Apple’s success cannot be copied because it is a magical process.
There is a great deal of evidence for the first hypothesis. The idea of Apple being successful is not something reflected in its stock price.Being valued lower than the average company in the S&P(標(biāo)準(zhǔn)普爾)500 indicates that to whatever degree Apple was successful in the past, it's not seen by the vast majority of observers as successful in the future.Why should one bother copying Apple if it results in being punished with a low valuation? If one works really hard at innovation and then that innovation becomes commoditized(商品化)very quickly, why should one bother?
When innovation practitioners are asked what makes Apple successful, the answers regarding the cause of this success border on the mythical. The climax of this hypothesis is the “chief-sorcerer” theory of success which places one magician, like Steve Jobs, in charge of casting all the right spells(符咒).
What about Apple’s own opinion of what makes it tick? Tim Cook refers to a great team and integration of hardware, software and services as unique Apple advantages. It’s a better explanation.Integration is something that can take a long time, but it is possible with great effort.A few companies are starting to make moves in that direction, but efforts are half-hearted.There is no “move the Earth” panic to become an integrated company from Samsung, Google or Microsoft.
My own suspicion is that Apple is more aware of what makes it special than it lets out. However, as Tim points out, it’s not a formula.It’s complex, it’s subtle, but it’s not magic.It’s a process that requires a degree of faith and courage.
【小題1】When a new product of Apple comes out, often it ______.
A.ruins an industry dramatically |
B.starts a revolution of an industry |
C.puts itself in an unbeatable position |
D.is soon overtaken by imitated products |
A. Apple is not a successful company |
B. they have no access to relevant resources |
C. It’s hard to find a magician like Steve Jobs |
D.being Apple takes more than time and efforts |
A.other companies are dedicated to integration |
B.Apple itself is fully aware of its unique advantages |
C.Apple will hold the leading position in this industry |
D.other companies don't have a great team as Apple does |
A.Acceptable. | B.Disappointing. | C.Unquestionable. | D.Convincing. |
