Koalas are pictured everywhere in Australia-on cleaning products, on “boxes of chocolate, on sports team shirts. Yet the animals live only in pockets along the east coast.
They once inhabited the entire coastline. The koala population dropped after farmers cut down many of the forests where koalas lived, and hunters killed the animals for their fur.
By the early 1900s, “koalas were basically shot out of south Australia,” says ecologist Bill Ellis, who studies the relationships among living things and their environments.
I recently joined Ellis and his team in a forest on St Bees Is land, 19 miles off the northeastern coast of Australia, with eight other volunteers. The island is a natural laboratory, yielding findings that may help protect koalas elsewhere on the continent.
The volunteers searched the island for koalas in the blue gum trees. When we found a koala, we gathered information about the trees in the area.
Blue gum is a species of the eucalyptus tree in which the funny leaf eaters spend most of their time. Eucalyptus trees are native to Australia, and their leaves are the main food source for koalas. Although koalas can walk on the ground, they are better suited for life in the canopy, the high cover of branches and leaves in a forest.
What has Ellis’s research told him so far? The population of St Bees seems to be healthy. Yet Ellis wonders whether the koalas might be heading for hard times. The island is overrun with wild goats, and Ellis thinks the goats are eating the small blue gum trees.
Without those trees, the koalas will run out of food in the future. Ellis hopes more research will help him understand how to protect the blue gum trees-and the koalas that depend on them. “I think that’s what everyone is trying to do-to make a difference.” Ellis says.
59. It can be inferred from the first paragraph that .
A. koalas’ pictures can be found everywhere in the world
B. koalas in Australia like to eat chocolate
C. only in the east coast of Australia can you find koalas
D. you can buy the pictures of koalas only in the east coast of Australia
60. Which of the following is TRUE about koalas?
A. They usually hide in a cave. B. They feed on the leaves of blue gum trees.
C. They prefer to walk on the ground. D. They don’t adapt to the high cover of branches.
61. What will Ellis most probably start to do next?
A. To keep the population of St Bees healthy.
B. To kill all the goats on the island.
C. To find some new foods for goats.
D. To protect blue gum trees for koalas.
62. The purpose of writing this passage is to .
A. expect people to concern about the life of koalas
B. record trip to Australia for watching koalas
C. present some basic knowledge of koalas’ life
D. introduce the ecosystem of wildlife in Australia

(A)
Chocolate might lower your chances of having a heart problem. According to a new study, a new study, a small amount of chocolate every day could decrease the risk of having a heart attack, by nearly 40 percent, German researchers followed nearly 20,000 people over eight years, sending them several questionnaires about their diet and exercise habits. They found people who had an an average of six grams of chocolate a day—or about one square of a chocolate bar—had a 39 percent lower risk of a heart attack.
Previous studies have suggested dark chocolate in small amounts could be good for you, but this is the first study to track its effects over such a long period. Experts think the flavonols(黄酮醇)contained in chocolate are responsible. Flavonols, also found in vegetables and red wine, help the muscles in blood vessels(血管)widen, which leads to a drop in blood pressure. “It’s a bit too early to come up with recommendations that people should eat more chocolate, but if people replace sugar or high-fat snacks with a little piece of dark chocolate, that might help,” said Brian Buijsse, a doctor at the German Institute of Human Nutrition in Nuthetal, Germany, the study’s lead author.
The people tracked by Buijsse and colleagues had no history of heart problems, had similar habits for risk factors like smoking and exercise, and did not vary widely in their Body Mass Index(身体质量指数).
Since the study only observed people and did not give them chocolate directly to test what its effects were, experts said more research was needed to determine the candy’s exact impact on the body. Doctors also warned that eating large amounts of chocolate could lead to weight gain. “This is not a prescription(指示)to eat more chocolate,” said Robert Eckel, a professor of medicine at the University of Colorado who is not linked to the study. “If we all had (a small amount of)chocolate every day for the rest of our lives, we would all gain a few pounds.” Eckel said it was amazing to find such a small amount of chocolate could have such a protective effect, but that more studies were needed to confirm its conclusions.
1.What is the main purpose of the article?
A.To suggest people eat as much dark chocolate as possible.
B.To warn people not to eat too much chocolate.
C.To tell people how to avoid a heart attack.
D.To report on a study about the benefits of chocolate.
2.Both Buijsse and Eckel believe that .
A.dark chocolate in enough amounts could be good for our health
B.eating large amounts of chocolate could lead to weight gain
C.we can cure our heart problems with dark chocolate
D.we’d better not advise people to eat more chocolate at present
3.Which of the following statements about the study is FALSE?
A.It’s the first time that the effects of dark chocolate has been examined.
B.The researchers followed nearly 20,000 people for over eight years.
C.The researchers didn’t give any diet instructions to the people followed by the study.
D.The study found that eating about six grams of chocolate a day was beneficial.
4.We can infer from the text that .
A.eating a small amount of dark chocolate will lower your blood pressure
B.scientists are now certain of the effects of dark chocolate
C.eating a little chocolate over a long period will not lead to weight gain
D.Flavonols can only be found in dark chocolate and red wine
People today expect to be examined when they enter a doctor"s office. At least they expect their blood pressure and temperature to be measured. However, as recently as two hundred years ago, a doctor"s treatment depended on talking with patients. In general, the communication between doctors and their patients was the most important part of medical methods. The modem age of medicine began with the stethoscope ,an instrument for listening to patients heartbeat and breathing. Before that, a doctor did not touch a patient. In fact, there was no such things as a medical examination.
The stethoscope──and all other medical instruments──-had a serious effect, on the practice of medicine. Doctors became better at finding the medical problems. More lives were saved. At the same time, doctors gave less importance to the communication between patients and doctors. Some doctors actually stopped talking to their patients. It is easy to understand why some sick people thought themselves as broken machines.

America’s No.1 health problem?A report published by the American Institute of Stress claims the biggest threat to health today is neither cancer nor AIDS.The report says:“it has been estimated that 75-90 percent of all visits to primary care physicians are for stress-related problems.’’
It is no exaggeration(夸张)to say that people today are being attacked by stress.According to the National Consumers League,“Work is the top source of stress for adults who have problems and stress in their lives(39%).Other sources include health(10%),concern about the economy(9%)and concern about international conflict and terrorism(4%)”
However, stress is hardly unique to the United States A British survey in 2005 estimated that ‘‘over half a million individuals in Britain believed in 2004 that they were experiencing work-related stress at a level that was making them ill”.As a result of“work-related stress,depression or anxiety”, there are“an estimated thirteen and a half million reported lost working days per year in Britain”
The picture is no less bleak in mainland Europe. According to the European Agency for Safety and Health at Work.“work-related stress has been shown to affect millions of European workers across all types of employment sectors’’ One survey revealed that there are “about 41 million workers affected by work-related stress each year.”
What about Asia?A report issued by a conference held in Tokyo concluded,“Job stress is a common concern among many countries in the world,both developing and industrialized countries”.The report observed that“several countries in East Asia,including China and Korea, have rapidly industrialized and economically grown”.These countries now have a lot of concerns on job stress and its harmful effects on workers’ health.

Sixteen years ago, Eileen Doyle"s husband, an engineer, took his four children up for an early morning cup of tea, packed a small case and was never seen or heard of again. Eileen was astonished and in a state of despair. They had been a happy family and, as far as she knew, there had been nothing wrong with their marriage.
Every day of the year a small group of men and women quietly pack a few
belongings and without so much as a note or a good--bye close the front door for the last time, leaving their debts, their worries and their confused families behind them.Last year, more than 1,200 men and nearly as many women were reported missing
from home--the highest in 15 years. Many did return home within a year, but others
rejected the past completely and are now living a new life somewhere under a
different identity.
To those left behind, this form of desertion is a terrible blow to their pride and self-confidence. Even the finality of death might be preferable. At least it does not imply rejection or failure. Worse than that, people can be left with an unfinished marriage, not knowing whether they will have to wait seven years before they are free to start a fresh life.
Clinical psychologist Paul Brown believes most departures of this kind to be well
planned rather than impulsive. "It"s typical of the kind of personality which seems
able to ignore other people"s pain and difficulties. Running away, like killing yourself,is a highly aggressive act. By creating an absence the people left behind feel guilty,upset and empty."
51. When her husband left home, Eileen Doyle________.
A. could not forgive him for taking the children
B. had been expecting it to happen for some time
C. could not understand why
D. blamed herself for what had happened
52. Most people who leave their families behind them___________.
A. do so without warning
B. do so because of their debts
C. come back immediately
D. change their names
53. Some people would even prefer the death to the running away of their spouse
Because_________.
A. their spouse would feel no pain during the death
B. their spouse death would not blow their pride and confidence
C. a desertion would not bring a feeling of rejection or failure
D. their spouse death would make them feel less painful
54. Which might be the best tire of the passage?
A. Broken Marriage B. New life after Desertion
C. A New Social Problem D. Desertion and its Influence
55. What can be inferred from the passage?
A. Many people choose to leave home quietly because they hate their family.
B. Paul Brown regards leaving home as an act of selfishness.
C. Those who are left behind will lose confidence and won"t marry again.
D. Eileen"s husband, together with his four kids, were probably killed in an accident.
Air travel is so quick nowadays that we can leave London after breakfast and be in New York in eight hours, yet what really upsets us most is that when we arrive it is lunch time while we have already had lunch on the plane and are expecting dinner.
Doctors say that air travelers are in no condition to work after crossing a number of time zones. Airline pilots, however, often live by their own watches.
小题1:After a long air travel, a traveler _______.
A.finds himself in a different world |
B.finds his brain apart from his body |
C.finds himself in Hong Kong the following morning |
D.has little sense about where he is |
A.they don’t trust others’ watches |
B.they don’t change their watches |
C.they make a living by their own watches |
D.they do as they used to do |
A.should rest when they arrive in New York from London. |
B.should work in good condition since they just finish a long journey. |
C.rest in a place with good condition. |
D.give up long journey since it makes them tired. |
