C
The Tasmanian devil is a rare marsupial(有袋动物)that lives only on the Australian island state of Tasmania. The doglike animal is rapidly disappearing. The Tasmanian state government estimates that the number of devils has dropped from around 150,000 in the mid-1990s to between 20,000 and 50,000 at the end of 2007.
The devil was declared an endangered species last week. It is being wiped out by a rare cancer called devil facial tumor(肿瘤)disease(DFTD). It spreads like a cold or flu from animal to animal. The disease is passed when one devil bites another. When the marsupial is infected with DFTD, large tumors develop around its mouth and neck. These growths make it impossible for the devil to eat. Many finally die from starvation within six months of being infected. As the name implies, the disease occurs only in Tasmanian devils and cannot be passed to humans.
You’ve got to remember that devils are scavengers(清扫工). They search through garbage for food. Throughout Tasmania people maintain outdoor dumps. If somebody threw out a carcass(兽类尸体), then the devils might actually consume quite large quantities of it.
The disease has not yet appeared in the devil population that lives in the northwest region of Tasmania. Conservationists have captured some of the healthy devils and sent them to a new home on the mainland of Australia. They hope these DFTD-free marsupials can be used to start a captive-breeding population. Once there are more disease-free devils, they can then repopulate the areas of Tasmania where the species are being wiped out.
Tasmanian devils play an important role in keeping the state’s ecosystem in balance. They keep the population of other predators, such as foxes and wild cats, in check. Ray Nias, head of World Wildlife Federation—Australia’s conservation program, says all Tasmanian wildlife will suffer if the devil becomes extinct. “If the devils go and the foxes and cats increase, it would be all over for a good dozen or more species of mammals, many of which are unique to Tasmania.”
46. It can be inferred that the Tasmanian devil is __________.
A. a hard-working street-cleaner B. a grass-eating animal
C. a meat-eating marsupial D. A DFTD origin
47. What’s the reason for making the Tasmanian devil endangered?
A. A rare disease called DFTD occurs in Tasmanian devils.
B. Dogs like to attack Tasmanian devils.

A. How should people protect the devils?
B. What do the Tasmanian people do with the devils?
C. What happens if the devils disappear?
D. Which animal is closely related to the devils?
49. What measures do Tasmanian people take to stop the devils from being wiped out?

B. Searching the cause of the disease and finding an effective treatment.
C. Developing new chemicals for the infected animals.
D. Moving all the devils to a new home on the mainland of Australia.
50. What’s true about DFTD?

New York City was dealing with a growing public health threat Sunday after tests confirmed (证实) that eight students at a private Catholic high school had contracted（感染）the same strain of the AH1N1 flu that has ravaged (重创) Mexico . Some of the school’s students had visited Cancun on a spring break trip two weeks ago .
Officials reported 68 U.S. cases of AH1N1 flu in five states so far , with the latest in Ohio and New York . Unlike in Mexico , cases in the United State have been mild – and U.S. health authorities can’t yet explain why .
In New York City , Centers for Disease Control and Prevention confirmed that there were 45 cases , Mayor Michael Bloomberg said .
About 100 students at St. Francis Preparatory School complained of flu-like symptoms(症状) ; further tests will determine how many of those cases are AH1N1 flu. St. Francis is the largest private Catholic high school in the nation , with 2, 700 students . The school canceled classes on Monday and Tuesday in response to the outbreak .
Bloomberg stressed that the New York cases were mild and many are recovering , but said that some family members of students also had flu symptoms .
In Mexico , health officials say a strain of AH1N1 flu has killed up to 160 people and sickened over 2, 000 . New York officials said the flu strain discovered in the patients here is the same strain as in Mexico , though all the New York cases are mild .
AH1N1 flu is a respiratory (呼吸道) disease of pigs caused by type A flu viruses . Human cases are uncommon but can occur in people who are around pigs . It also can be spread from person to person . Symptoms include a high fever , body aches , coughing , sore throat and respiratory congestion .
49.The passage seems to suggest that _________ .
New York City hasn’t done enough to prevent the disease

Arthritis, stroke, osteoporosis(骨关节炎), heart disease and dementia are what we’ve got to look forward to in old age. But conditions like these don’t have to be impossible to avoid, says New Zealand cook Robyn Martin. She firmly believes that we are what we eat and we can choose to consume foods that can slow the aging process and even prevent certain illnesses. That’s why her latest cookbook is devoted to recipes that use ingredients with a large number of anti-aging benefits. Stop the Clock—the Anti-Aging cookbook looks at a variety of health problems—from brain decline and joint aches and pains to heart disease and high cholesterol(胆固醇)—then lists foods that can improve or prevent them and offers a selection of recipes using those ingredients. “I wrote this book so I can offer people lots of information about foods that can give them a better old age.”Six foods that can help slow the aging process:
1. Lentils
The important substance included in lentils is the one that can help you avoid the unpleasant symptoms of menopause(更年期), like mood swings.
2. Blueberries
Blueberries slow and, in some cases, reverse damage in aging brains. They are also rich in some chemicals which keep your looking young and help relieve arthritic(关节炎的) pain.
3. Carrots
Carrots have high levels of beta-carotene, which changes to vitamin A in the body. So they may help with memory, do good to the skin and are also thought to lower cholesterol.
4. Oats
The protein, calcium and phosphorus in oats all help build strong bones and connective tissue. The fibre they contain helps lower cholesterol and high blood pressure.
5. Spinach
Spinach is a good source of two important substances involved in protecting the DNA in our cells from oxication(氧化). It not only helps to strengthen the memory and turn off genes that can step up aging, but also can help improve the symptoms of osteoarthritis.
6. Soy
Soy products help lower blood pressure and cholesterol levels and are rich in phytoestrogens, which can help prevent hormone-related cancers. Soy can also be helpful to the skin, making it firm and youthful.
Did you know? Tomatoes contain a powerful substance which is not only useful for preventing problems in the heart, and lungs, but also prevents diseases like cancer. To gain the most benefit, tomatoes should be cooked.
64. If memory often fails you, which of the following combination will be good to you?
A. soy and carrots B. oats and soy
C. lentils and blueberries D. carrots and spinach
65. This passage mainly deals with _____.
A. foods and ingredients B. foods and health C. foods and nutrition D. foods and diseases
66. The passage is written _____.
A. to tell the readers recipes play an important role in keeping healthy
B. to advertise the foods mentioned in the passageC. to tell the readers how to slow the aging process
D. to tell the readers how to cure some diseases by taking right foods
C
Patients and doctors alike have long believed in the healing (治疗) power of humor. It is claimed that humor not only affects patients’ moods, but can actually help them recover faster.
Several studies seem to support this. Patients in better spirits are known to have higher immune cell counts. Some have even claimed to have healed themselves of serious illnesses by reading comics and watching comedies.
Despite all this, many researchers are not convinced. They point out the fact that many sufferings have been known to disappear naturally, with or without a daily dose of laughter. They also say that while optimism in general does seem to be related to better health, it is hard to tell which comes first.
Humor in times of stress, however, clearly makes us feel better. On one level, it takes our minds off our troubles and relaxes us. On another, it releases powerful endorphins, a chemical produced by your body that reduces pain.
There are cases where the appreciation of a good joke is indeed directly related to a person’s health. It can show, for example, whether a person has suffered damage to one particular area of the brain: the right frontal lobe (额叶).
Scientists confirmed this by having people read jokes and asking them to choose the funniest endings from a list. Subjects with normal brains usually chose endings that were based on a relatively complex synthesis (综合) of ideas. Subjects with specifically located brain damage, however, responded only to slapstick (闹剧) endings, which did not depend on a particular context. When pressed, the brain-damaged subjects saw the logic in the correct endings. They simply did not find them funny.
Of course, humor is largely an individual matter. Next time your friend does not get one of your jokes, there is no need to accuse him of being a lamebrain. However, you might suggest that he lighten up—for the health of it.
63. We can infer from the passage that ________.
A. all researchers have agreed on the healing power of humor
B. people seldom accuse their friends of not understanding jokes
C. the author holds a positive attitude to the healing power of humor
D. reading comics will surely become a popular way of treating diseases
64. Which of the following statements is NOT true?
A. Many researchers are not convinced of the healing power of humor.
B. Patients in bad moods are known to have higher immune cell counts.
C. Optimism in general does seem to be related to better health.
D. People should try their best to cheer up for their good health.
65. Scientists had some people read jokes and asked them to choose the funniest endings from a list to confirm that ________.
A. the brain-damaged people are different from those with normal brains
B. a person with a normal brain usually responds to slapstick endings
C. a person suffering certain brain damage doesn’t appreciate a good joke
D. humor takes our minds off our troubles by releasing powerful endorphins
66. Which would be the best title for the passage?
A. Which comes first, humor or health? B. Humor can cure different illnesses
C. People need humor in times of stress D. Humor contributes to good health
“Open your heart to others and try to understand,
When someone reaches for you, hold out to them your hand,
Follow your heart, no matter what other people say,
Do things that make you able to smile throughout your day,
Treat other people, the way you would like them to treat you,
Do what you know is right and to your heart and self stay true,
Remember what life is all about, it is how you make people feel,
What you do, where you go, and making dreams become real,
Helping people through, in hard times of pain and strife,
What you do for others, is what is important in this life.
Look deeper and don’t judge people by what is on the outside,
It is what is inside that counts and what people often hide,
Care, help, love, be honest, and be kind,
With purity and goodness within yourself, it is happiness you will find.
Do all you can in the time you have, you won’t always be around,
Recapture the joy of little things, that once were easily found,
And if you can do all this and live a life of love,
You will be helped through life, by all those up above.”
I will leave you with the inspiring words of our late genius, Albert Einstein:
“There are two ways to live life. One is as though nothing is a miracle (奇迹). The other is as though everything is a miracle.”
60. The passage is mainly about ______.
A. living a life of love B. helping those in need
C. taking back the joy of life D. separating ourselves from others
61. According to the passage, which statement is true?
A. Treating others the way others treat you is right for your life.
B. Making your dream become real is selfish in your life.
C. Judging people by what is inside counts.
D. Doing what you can makes yourself happy.
62. The underlined sentence in the last paragraph probably means _________.
A. Different ways of life lead to completely different results
B. Life is not always full of miracles
C. There are two kinds of miracles in life
D. Looking for miracles in life helps people find happiness
Dr. Aiken believes there are several reasons why couples grow alike. One reason has something to do with imitation. One person tends to copy or do the same as someone else without knowing it. He says human beings copy the expressions of the faces of their loved ones. Another possible reason, he says, is the common experience of the couples. There is a tendency for people who have the same life experience to change their faces in similar ways. For example, if a couple suffered a lot of sad experiences, their faces are likely to change in a similar way.
56. The main purpose of the passage is to .
tell how couples look like each other
show the life experience of husband and wife
explain why couples grow alike
describe the study on a number of married people
57. The judges failed to .
tell couples by looking at their photos taken when they got married
tell happily-married couples from sadly-married couples
discover the difference of each partner
understand Dr. Aiken’s study
58. The underlined sentence “Their judgments were .
| A．quite successful | B．based on facts | C．only by luck | D．totally wrong |
happily-married couples are often richer than other couples
couples who look alike can live longer
the influence between couples can be quite strong
all couples have been proved to grow alike
