阅读理解。     Modern man has cleared the forests for farmland and for wood, and has also carelessly burned them.
More than that, though, he has also interfered (干涉) with the invisible bonds between the living things in
the forests. There are many examples of this kind of destruction. The harmfulness of man"s interference
can be seen in what happened many years ago in the forest of the Kaibab plateau (凯亚巴布高原) of
northern Arizona. Man tried to improve on the natural web of forest life and destroyed it instead.
     The Kaibab had a storybook forest of large sized pine, Douglas fir, white fir, blue and Engelmann spruce.
In 1882 a visitor noted,"We, who... have wandered through its forests and parks, have come to regard it as
the most enchanting region it has ever been our privilege (特权) to visit." This was also the living place of the
Rocky Mountain mule deer. Indians hunted there every autumn to gather meat and skins. The forest also had
mountain lions, timber wolves and bobcats that kept the deer from multiplying too rapidly.
     Then, in 1906, President Theodore Roosevelt made the Kaibab a national game preserve. Deer hunting was
forbidden. Government hunters started killing off the deer"s enemies. In 25 years" time, 6,250 mountain lions,
wolves and bobcats were killed. Before the program, there were about 4,000 deer in the Kaibab, by 1924,
there were about 100,000.
     The deer ate every leaf and twig they could reach. But there was not nearly enough food. Hunting of deer
was permitted again. This caused a slight decrease in the deer herd (鹿群),but a far greater loss resulted from
starvation (饥饿) and disease. Some 60 percent of the deer herd died in two winters. By 1930 the herd had
dropped to 20,000 animals. By 1942 it was down to 8,000. 1. The destruction of the environment of the Kaibab resulted from _____. A. turning the forest into cultivated land
B. interfering with natural cycle of forest life
C. forest fires caused by man"s carelessness
D. cutting the trees for building materials 2. "Engelmann spruce"(Para. 2) is most likely the name of _____. A. a tree
B. an animal
C. a mountain
D. a game3. The number of the deer in the Kaibab had increased enormously in _____ years" time. A. 25
B. 6
C. 18
D. 12 4. Years later, large numbers of deer in the Kaibab died mainly because of _____. A. the cold
B. the organized kill
C. the shortage of food
D. the poor management

阅读理解。     Many people turn to the web for health advice. Women use the Internet to look for health information
for themselves and their family significantly more than men, research has found. The study, by independent
research company Datamonitor, says that for this reason health sites should make greater efforts to appeal
to women by covering their health concerns.
     The researchers, who quizzed 4,531 adults across France, Germany, Italy, Spain, the UK and the US,
found that websites have become just as important as some off-line sources of health information. Fifty-seven
percent of those who looked for health information in the past 12 months consulted Internet sources.
     Report author Yvonne MacPherson said,"A distinct advantage of the Internet as a source of health
information is that information is easily accessible and can be read in private and at the leisure of the Internet
user." "Good health sites are not meant to replace interaction with a physician. Rather, they help patients
prepare for appointments and take more responsibility for their health." He added.
     Currently, 32-34% of adults aged 18 to 54 used the Internet to search for health information. This number
decreases to 27% in the 55 to 64 age group, and further to 14% in the 65 and over age group. Young Internet
users often conduct online health research on behalf of older family members who do not use the Internet.
     However, Datamonitor says that the audience for health information online will grow naturally as the
population ages, and more and more people grow up with the net. It recommends that website operators
focus their efforts on building a good long-term relationship with their existing consumers, rather than on
attempting to attract non-Internet users.1. What is the main subject discussed in the passage?

A. The popularity of health websites.
B. The importance of health advice.
C. The advantage of the Internet sources.
D. The increase of people"s health concerns.

2. According to Yvonne MacPherson, health information online could be described as ______.A. acceptable
B. convenient
C. accurate
D. abundant3. Which of the following is NOT true? A. Health websites should pay more attention to women"s health concerns.
B. A good health site should be able to replace interaction with a doctor.
C. The old tend to make less use of the Internet for health information.
D. The young may be the potential audience of health information online.

阅读理解。     At first sight, you would think the collection of hundreds of colored shards (碎片) could be a work of
abstract art. But the objects are the contents of the stomach of a sea turtle that lost its battle with plastic
pollution.
     Environmentalists examined the stomach of the turtle found off the coast of Argentina. What they found
is the symptom of the increasing threat to sea turtles from a human addiction to plastic.
     Sea turtles often mistake plastic items for jellyfish or other food. Ingesting (摄取) ocean pollution can
cause a digestive blockage and internal cuts. The result can be dangerous, followed by death.
     Humans produce 260 million tons of plastic a year. When those products are pulled into the sea"s currents,
the plastics are just broken into smaller pieces which are consumed by marine life at the bottom of the food
chain. An examination of a green turtle found off Florida discovered that, over the course of a month, the
animal"s faeces (粪便) had contained 74 foreign objects, including "four types of balloons, different types of
hard plastic, a piece of carpet-like material and two 2-4 mm tar balls."
     "The oceans have become on giant refuse bin for all manner of plastics. All sea turtle species may be
seriously harmed," according to the biologists Colette Wabnitz, from the University of British Columbia."The
symptom of this growing crisis can be seen inside and on sea turtles as well as their oceanic and terrestrial
habitats. It is urgently necessary to directly confront the source of plastic pollution, redesign packaging and
rethink the very idea of "throwaway culture"."
      Almost all marine species, from plankton to whales, have ingested plastic. But, even in small quantities,
plastic can kill sea turtles, the biologists said.
     Fifty out of 92 turtles found dead, stranded on the shorelines of Rio Grande do Sul state in Brazil, had
ingested a"considerable amount of man-made debris". 1. What"s the passage mainly about?A. How to prevent the sea turtle from plastic.
B. Why plastic is dangerous to the sea turtle.
C. Sea turtles suffering from plastic pollution.
D. Protecting the sea turtle from being polluted. 2. The author mentions the "throwaway culture" probably in a(n) ______ tone. A. praising
B. positive
C. comedic
D. ironic3. The underlined word in the last paragraph probably means _____. A. a kind of food
B. a kind of fish
C. pieces of rubbish
D. pieces of cloth 4. The paragraph following the last one will probably talk about ______.A. the way the biologists examined the sea turtle
B. some tips on how to make sea turtles avoid plastic
C. how to prevent plastic pollution
D. the reason why we should protect the sea turtle

阅读理解。     We have met the enemy and he is ours. We bought him at a pet shop. When monkey-pox, a disease usually
found in the African rain forest suddenly turns up in children in the American Midwest. It"s hard not to wonder
of the disease that comes from foreign animals is homing in on human beings. "Most of the infections (感染)
we think of as human infections started in other animals." says Stephen Morse, director of the Center for Public
Health Preparedness at Columbia University.
     It"s not just that we"re going to where the animals are; we"re also bringing them closer to us. Popular foreign
pets have brought a whole new disease to this country. A strange illness killed Isaksen"s pets and she now thinks
that keeping foreign pets is a bad idea. "I don"t think it"s fair to have them as pets when we have such a limited
knowledge of them." says Isaksen.
     "Laws allowing these animals to be brought in from deep forest areas without stricter control need changing."
says Peter Schantz. Monkey-pox may be the wake-up call. Researchers believe infected animals may infect their
owners. We know very little about these new diseases. A new bug (病毒) may be kind at first. But it may
develop into something harmful (有害的). Monkey-pox doesn"t look a major infectious disease. But it is not
impossible to pass the disease from person to person. 1. We learn from Paragraph l that the pet sold at the shop may _____. A. come from Columbia
B. prevent us from being infected
C. enjoy being with children
D. suffer from monkey-pox 2. Why did Isaksen advise people not to have foreign pets? A. They attack human beings.
B. We need to study native animals.

阅读理解。     I"m a skeptic (怀疑论者) when it comes to the benefits of taking vitamins and other supplements. We
swallow far more than any other country- yet we"re not the healthiest folks by far, nor do we live the longest.
     There"s more bad news for vitamins this week: Turns out that taking folic acid (叶酸) and vitamin B12
supplements doesn"t prevent heart attacks or death, according to a major new study in the Journal of the
American Medical Association. It was hoped they would, since the vitamins do reduce levels of homocysteine (高半胱氨酸), an amino acid (氨基酸) that is higher in the blood of people who have a higher risk of heart
disease. In fact, homocysteine was reduced 30 percent after one year of treatment in the participants who
took both vitamins. But in the following three years, just as many vitamin takers died as those who didn"t take
the vitamins. Even worse, the study was stopped early because another similar study suggested that there may
be an increased risk of cancer from taking B vitamins.
      I had been taking a health-food store monster multivitamin (综合维生素剂) for months. Coincidentally, I
had been experiencing some strange numbness in my legs that was starting to scare me. I remember sitting in
a long meeting with my ankles crossed, and when I tried to stand up I crumpled on the floor and hit my chin
on the glass coffee table because my leg had gone completely numb and worthless. As I sat there and shook
my leg, I got that"pins and needles" feeling and soon was OK. But it scared me enough to make an appointment with a neurologist, who suggested an MRI to rule out stroke, or a brain tumor(肿).
     While I"ll never know for sure if the vitamins caused my problem, many, many studies have reminded us
that pill forms of vitamins and minerals don"t provide the same benefit as getting them from food. There"s a lot
we don"t know about how the human body works. Until we know more, I"m getting most of my vitamins from
the farmer"s market.1. What can we know from the last paragraph? A. The writer is getting most of pill forms of vitamins from the markets.
B. The writer continues to take vitamins in great quantities.
C. The writer is getting vitamins from food, which can provide more benefits.
D. The writer will never take pill forms of vitamins and minerals.2. Why do people take folic acid and vitamin B12 supplements? A. They want to stop heart attacks or live longer.
B. They want to live longer.
C. They want to increase risk of cancer.
D. They want to experience some strange numbness. 3. Which of the following is not true according to the passage?A. It was the multivitamin he took that caused the writer to get the "pins and needles" feeling.
B. Taking more vitamins will not make a man healthier or live longer.
C. The vitamins can reduce levels of homocysteine in our body.
D. The less homocysteine in our blood, the less chance we"ll have heart attacks. 4. The best title of the passage can be ______. A. Vitamins: Benefit Us a Lot
B. Vitamins: No Help for Your Heart
C. Vitamins: Bad for the Brain, Too
D. Some Bad News About Vitamins.
