Forests in the northern half of the globe could be growing faster now than they were 200 years ago as a result of climate change, according to a study of trees in eastern America. The trees appear to have faster growth rates due to longer growing seasons and higher concentrations (浓度) of carbon dioxide in the ___41___.

Geoffrey Parker, a scientist at the Smithsonian Environmental Research Centre in Edgewater. Maryland, said that the increase ha the rate of growth was unexpected and might be ___42___ to the higher temperatures and longer growing seasons documented in the region. The growth may also be influenced by the significant ___43___ in atmospheric CO2, he said.

"We made a list of reasons these forests could be growing faster and then excluded half of them," Dr. Parker said. Their study suggests that northern forests may become increasingly important in ___44___ the influence of man-made CO2 on the climate.

Dr. Parker and his colleagues have ___45___ out a detailed record of the trees on a(n) ___46___ basis since 1987. They calculated that due to the global warming the forest is producing   ___47___ tons of wood each year.

The scientists ___48___ the land with trees at different stages of growth and found that both young and old trees were showing increased growth rate. More than 90 per cent of the tree groups had grown by between two and four times faster than the scientists had ___49___ from estimates of the long-term rates of growth.

Section B

Directions: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.

(A)

The elephant was lying heavily on its side, fast asleep. A few dogs started barking at it. The elephant woke up in a terrible anger: it chased the dogs into the village where they ran for safety.

That didn't stop the elephant. It destroyed a dozen houses and injured several people. The villagers were scared and angry. Then someone suggested calling Parbati, the elephant princess.

Parbati Barua's father was a hunter of tigers and an elephant tamer. He taught Parbati to ride an elephant before she could even walk. He also taught her the dangerous art of the elephant round-up -- how to catch wild elephants.

Parbati hasn't always lived in the jungle. After a happy childhood hunting with her father, she was sent to boarding school in the city. But Parbati never got used to being there and many years later she went back to her old fife. "Life in the city is too dull. Catching elephants is an adventure and the excitement lasts for days after the chase," she says.

But Parbati doesn't catch elephants just for fun. "My work," she says, "is to rescue man from the elephants, and to keep the elephants safe from man." And this is exactly what Parbati has been doing for many years. Increasingly, the Indian elephant is angry: for many years, illegal hunters have attacked it and its home in the jungle has been reduced to small pieces of land. It is now fighting back. Whenever wild elephants enter a tea garden or a village, Parbati is called to

guide the animals back to the jungle before they can kill.

The work of an elephant tamer also involves love and devotion. A good elephant tamer will spend hours a day singing love songs to a newly captured elephant. "Eventually they grow to love their tamers and never forget them. They are also more loyal than humans," she said, as she climbed up one of her elephants and sat on the giant, happy animal. An elephant princess indeed!

1. For Parbati, catching elephants is mainly to             .

A. get long lasting excitement              B. keep both man and elephants safe

C. send them back to the jungle             D. make the angry elephants tame

2. Before Parbati studied in a boarding school,            .

D. she was taught how to hunt tigers

3. Indian elephants are getting increasingly angry and they revenge because __________.

A. they are caught and sent for heavy work                

B. illegal hunters capture them and kill them

C. they are attacked and their land gets limited

D. dogs often bark at them and chase them

4. The passage starts with an elephant story in order to explain that in India _________.

The following card includes a brief summary and a short assessment of a research paper. It can provide a guide for further reading on the topic.

Trevor, C. O., Lansford, B. and Black, J. W., 2004, "Employeeturnover (人事变更) and job performance: monitoring the influences of salary growth and promotion", Journal of Armchair Psychology, vol. 113, no.1, pp. 56-64.

In this article Trevor et al. review the influences of pay and job opportunities in respect of job performance, turnover rates and employees' job attitude. The authors use data gained through organizational surveys of blue-chip companies in Vancouver, Canada to try to identify the main cause of employee turnover and whether it is linked to salary growth. Their research focuses on assessing a range of pay structures such as pay for performance and organizational reward plans. The article is useful as Trevor et al. suggest that there are numerous reasons for employee turnover and a variety of differences in employees' job attitude and performance. The main limitation of the article is that the survey sample was restricted to mid-level management, thus the authors indicate that further, more extensive research needs to be undertaken to develop a more in-depth understanding of employee turnover and job performance. As this article was published in a professional journal, the findings can be considered reliable. It will be useful additional information for the research on pay structures.

1. The research paper published is primarily concerned with    

A. the way of preventing employee turnover

B. methods of improving employee performance

C. factors affecting employee turnover and performance

D. pay structures based on employee performance

2. As is mentioned in the card, the limitation of the research paper mainly lies in that      .

A. the data analysis is hardly reliable

B. the research sample is not wide enough

C. the findings are of no practical value

D. the research method is out-of-date

3. Who might be most interested in this piece of information?

A. Job hunters.

B. Employees in blue-chip companies.

C. Mid-level managers.

D. Researchers on employee turnover.

The 2012 London Olympics had enough problems to worry about. But one more has just been added - a communications blackout caused by solar storms.

After a period of calm within the Sun, scientists have detected the signs of a flesh cycle of sunspots that could peak in 2012, just in time for the arrival of the Olympic torch in London.

Now scientists believe that this peak could result in vast solar explosions that could throw billions of tons of charged matter towards the Earth, causing strong solar storms that could jam the telecommunications satellites and interact links sending five Olympic broadcast from London.

"The Sun's activity has a strong influence on the Earth. The Olympics could be in the middle of the next solar maximum which could affect the functions of communications satellites," said Professor Richard Harrison, head of space physics at the Rutherford Appleton Laboratory in Oxfordshire. 

At the peak of the cycle, violent outbursts called coronal mass ejections (日冕物质抛射) occur in the Sun's atmosphere, throwing out great quantities of electrically-charged matter. " A coronal mass ejection can carry a billion tons of solar material into space at over a million    kilometres per hour. Such events can expose astronauts to a deadly amount, can disable satellites, cause power failures on Earth and disturb communications," Professor Harrison added. The risk is greatest during a solar maximum when there is the greatest number of sunspots.

Next week in America, NASA is scheduled to launch a satellite for monitoring solar activity called the Solar Dynamics Observatory (SDO), which will take images of the Sun that are 10 times clearer than the most advanced televisions available.

The Rutherford Appleton Laboratory helped to make the high-tech cameras that will capture images of the solar flares (太阳耀斑) and explosions as they occur.

Professor Richard Hold away, the lab's director, said that the SDO should be able to provide early warning of a solar flare or explosion big enough to affect satellite communications on Earth "If we have advance warning, we'll be able to reduce the damage. What you don't want is things switching off for a week with no idea of what's caused the problem," he said.

1. The phrase "communications blackout" in paragraph 1 most probably refers to      during the 2012 Olympics.

A. the extinguishing of the Olympic torch

B. the collapse of broadcasting systems

C. the transportation breakdown in London

D. the destruction of weather satellites

2. What can be inferred about the solar activity described in the passage?

A. The most fatal matter from the corona falls onto Earth.

B. The solar storm peak occurs in the middle of each cycle.

C. It takes several seconds for the charged matter to reach Earth.

D. The number of sunspots declines after coronal mass ejections.

3. According to the passage, NASA will launch a satellite to _________.

A. take images of the solar system         B. provide early warning of thunderstorms

C. keep track of solar activities            D. improve the communications on Earth

4. Which of the following might be the best title of the passage?

A. Solar Storms: An Invisible Killer

B. Solar Storms: Earth Environment in Danger

C. Solar Storms: Threatening the Human Race

D. Solar Storms: Human Activities to Be Troubled

Section C

Directions: Read the following text and choose the most suitable heading from A-F for each

paragraph. There is one extra heading which you do not need.

A. Drug overuse and its consequence

B. The problem of drug overuse in America

C. Benefits of medicine and its wise use

D Female drug overuse with reference to that of males

E Misuse of medicine among the young generation

F. Improper use of medicine among senior citizens

76 .               

Nowadays. millions of people misuse and even overuse pain medications and other drugs. Research by the American National Institute on Drug Abuse (NIDA, 1999) shows that around 2% of the population over age 12 were using drugs non-medically.

77.

NIDA views medications as a powerful force for good in the contemporary world. They reduce and remove pain for millions of people suffering from illness and disease. They make it possible for doctors to perform complicated surgery to save lives. Many people afflicted by serious medical conditions are able to control their symptoms and become active, contributing citizens. NIDA points out that most individuals who take these drags use them in a responsible.

78.

Nevertheless, overuse of drugs such as opioids, central nervous system (CNS) depressants and stimulants does lead to harmful reliance in some people and is therefore becoming a serious public health concern. Although this abuse affects many people worldwide, particular trends of concern to the medical profession in the US appear among older adults, teenagers arid women.

79.

Though it may be a surprise to many, the misuse of medications may be the most common form of drug abuse among the elderly. Dr Kenneth Schrader of Duke University, North Carolina states that although the elderly represent about 13% of the US population, those aged 65 and over account for the consumption of one third of all drugs. People in this age group use medications roughly three times more than the general population and have poorer compliance with instruction for use. In another study of elderly patients admitted to treatment programs, 70% were women who had overused medicines.

80.

Unfortunately, this trend among women does not only affect those aged over

In general, among women and men who are using either an anti-anxiety drug or a sedative, women are twice as likely to become addicted. In addition, statistics compiled for 12-17 year olds show that teenage girls are more likely than teenage boys to begin overusing psychotherapeutic medication such as painkillers, tranquillizers, stimulants and sedatives.
