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 (栖息地) 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.
endangered species?
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.
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.
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
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.
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.

people, so many students are wondering why they have to learn it.
Our nature includes not just the humans but plants and animals as well. Everything in our environment
is connected in a complex cycle. If you have a better understanding of how animals behave, then you
would value nature better.
Some animals, like sharks and snakes, are often misunderstood by people. They are thought of as
human killers, and this is mainly because we don"t understand why they behave that way. Zoology would
help you learn their natural behavior as well as their habits, so you would understand why they behave in
a defensive manner when they feel threatened.
Studying zoology would help people know the real facts about animals. One of the sad facts is the
decreasing numbers of some species of animals. It makes people realize that there is a need for nature to
be always balanced. We need animals to keep the balance in our environment and for humans to survive.
Zoology helps us learn the needs that animals have and we can respond by thinking of solutions we can
give to the endangered species of animals.
Technological progress is needed for a country to grow in terms of its economy; however, it should
not force us to destroy our rainforests and oceans. People should realize that our modern lives should
include the lives of the animals. Animals should not be contained in zoos but live in their natural habitats.
We will learn that every living creature on the earth has the right to own a habitat and we need to fight for
them to have permanent habitats.
B. work with zoologists better
C. have an appreciation for nature
D. understand the animals" behavior
B. people should communicate with animals
C. animals keep their behavior a myth
D. animals are human killers
B. spread the knowledge of animals
C. satisfy the animals" needs
D. protect endangered animals
B. the importance of studying zoology
C. the basic knowledge of zoology
D. the ways of protecting animals
In fact, they say by the age of eighty-five, people are happier with their life than they were when they were
eighteen years old.
The findings came from a survey of more than 340,000 adults in the United States. The Gallup (民意调查)
Organization questioned them by telephone in 2008. At that time, the people were between the ages of eighteen
and eighty-five.
The researchers asked questions about emotions like happiness, sadness and worry. They also asked about
mental or emotional stress.
Arthur Stone at Stony Brook University in New York led the study. His team found that levels of stress
were highest among adults between the ages of twenty-two and twenty-five. The findings showed that stress
levels dropped sharply after people reached their fifties. Happiness was highest among the youngest adults and
those in their early seventies. The people least likely to report feeling negative emotions were those in their
seventies and eighties.
Researchers say they do not know why happiness increases as people get older. One theory is that, as
people grow older, they grow more thankful for what they have and have better control of their emotions.
They also spend less time thinking about bad experiences.
Professor Stone says the emotional patterns could be linked to changes in how people see the world, or
maybe even changes in brain chemistry.
The researchers also considered possible influences like having young children, being unemployed or being
single. But they found that influences like these did not affect the levels of happiness and well-being related to
age.
The study also showed that men and women have similar emotional patterns as they grow older. However,
women at all ages reported more sadness, stress and worry
A. only when people get older will they feel happier
B. stress levels among the youngest are the highest
C. older people tend to be grateful
D. older people usually have no worries
B. they are physically weak
C. they have better self-control
D. they are more emotional
B. How to live better.
C. How to keep happier.
D. Why women are less happier.
B. introduce a scientific finding
C. describe how to do research
D. talk about human emotions
built a company around sleep deprivation (睡眠不足).
Jason Donahue, Ben Rubin and Eric Shashoua were working late nights in Brown"s business and
engineering schools. They began thinking about ways to sleep better. They discovered they weren"t alone in
burning the midnight oil. Around 20% of Americans get less than six hours of rest a night.
The friends imagined a smart alarm clock that could track how much time people spend in the most
restorative (有回复作用的) stages of the sleep cycle: REM (rapid eye movement)and deep sleep. What would
it cost to design such a thing? Five years of research, 20 employees, $14 million and a whole lot of doubting
from investors and scientists.
Their company, Zeo, based in Newton, Mass, launched its product in June, 2009. The Zeo device uses a
headband with tiny sensors (传感器) that scan your brain for signs of four sleep states-REM, light, deep and
waking sleep.The smart alarm clock displays a graph of your sleep pattern and wakes you as you"re not in
REM sleep (which is when you"re least groggy). In the morning you can upload the data to the company"s
Web site, and so track your sleep over time.Most of the feedback comes in the form of Zeo"s ZQ score
showing how well you"ve slept.
"Zeo allows people to unlock this black box of sleep," says Dave Dickinson, a health-care CEO.
Whether any of this actually improves sleep is up to the consumer, who will also need to make lifestyle
changes like cutting out alcohol before bedtime or caffeine after 3 pm.
For now the company is selling Zeo online only. Dickinson also plans to spread it to countries such as
Australia, where sleep deprivation approaches US level
B. People suffering sleeping problems.
C. People having access to the Internet.
D. People having bad lifestyles.
B. To earn enough money for their study.
C. To improve the quality of people"s sleep.
D. To enjoy their life while working at night.
B. were widely supported by scientists
C. worked by themselves all the time
D. attracted many investors .
B. It needs more personal efforts to make Zeo function better.
C. A large quantity of Zeo devices have been sold in Australia.
D. Consumers can go to the Zeo company to purchase Zeo in person
a technique that could help track the movements of criminal suspects or unidentified murder victims.
The method relies on measuring how chemical variations in drinking water show up in people"s hair.
"You"re what you eat and drink, and that"s recorded in your hair," said Thure Cerling, a geologist at the
University of Utah.
While U.S. diet is relatively identical, water supplies vary. The differences result from weather patterns.
The chemical composition of rainfall changes slightly as rain clouds move.
Most hydrogen and oxygen atoms in water are stable, but traces of both elements are also present as
heavier isotopes (同位素). The heaviest rain falls first. As a result, storms that form over the Pacific deliver
heavier water to California than to Utah.
Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen
isotopes along a strand of hair, scientists can construct a geographic timeline. Each inch of hair corresponds
to about two months. Cerling"s team collected tap water samples from 600 cities and constructed a map of
the regional difference. They checked the accuracy of the map by testing 200 hair samples collected from
65 barber shops. They were able to accurately place the hair samples in broad region roughly corresponding
to the movement of rain systems.
"It"s not good for pinpointing (精确定位)," Cerling said. "It"s good for eliminating many possibilities."
Todd Park, a local detective, said the method has helped him learn more about an unidentified woman
whose skeleton was found near Great Salt Lake. The woman was 5 feet tall. Police recovered 26 bones, a
T-shirt and several strands of hair. When Park heard about the research, he gave the hair samples to the
researches. Chemical testing showed that over the two years before her death, she moved about every two
months. She stayed in the Northwest, although the test could not be more specific than somewhere between
eastern Oregon and western Wyoming.
"It"s still a substantial area," Park said,"But it narrows its way down for me."
B. A person"s hair may show where they have lived.
C. Hair analysis accurately identifies criminal suspects.
D. The chemical composition of hair varies from person to person.
B. The water it delivers becomes lighter when it moves inland.
C. Its chemical composition is less stable than in other areas.
D. It gathers more light isotopes as it moves eastward.
B. A collection of hair samples from various barber shops.
C. A method to measure the amount of water in human hair.
D. A chart illustrating the movement of the rain system.
B. It helps the police determine where a crime is committed.
C. It helps the police narrow down possibilities in detective work.
D. It helps identify the drinking habits of the person under investigation.

The Chinese tradition of raising sons to support parents in their old age has been weakened by the rapidly
growing economy and improved standard of living. As is the case with developed countries, China faces an
aging society. People are living longer and having fewer children. Therefore many Chinese families are falling
into a 4-2-1 family pattern: a couple raises one child and supports four elderly parents. But few realize this
problem.
The aging of the population is a trend that now affects a growing number of countries. Not long ago, the
Information Office of the State Council, China"s cabinet, issued a white paper on measures China is taking to
help its elderly population. The paper said China"s population entered the aging phase (阶段) at the end of the
20th century as the proportion of people aged 60 and above accounted for over 10 percent of the entire
population. By the end of 2005, China had nearly 144 million people over 60, accounting for 11 percent of the
population, according to the white paper.
An expanding aged population inevitably means that many issues must be settled, as the problem concerns
every aspect of society. It puts more pressure on each family, causing disturbing economic consequences
and serious social problems. It also challenges the labor force supply and the pension system.
"I used to think that it"s not an issue for me to provide for the aged," said Han, whose parents and
parents-in-law all enjoy pensions and medical insurance. But last year Han"s father suffered a serious illness
and afterward Han began to feel the pressure on his shoulders.
B. The problem of the pension system.
C. More pressure on the family.
D. Unemployment.
B. China will encourage young couples to have more than one child
C. many people haven"t realized the problem of an aging society
D. children will not support their parents in an aging society
B. naturally
C. hopefully
D. unluckily
B. most of the developing countries face an aging society
C. countries with a large population face an aging society
D. more and more developed countries face an aging society
