A new study has revealed that non-smokers who repeatedly breathe in others" tobacco smoke are more
likely to have some degree of hearing loss. Researchers studied a total of 3307 adults aged between 20 and
69. The degree of hearing loss in each ear was assessed by testing the ability to hear pure tones over a range
of frequencies from 500 Hz (low) to 8000 Hz (high).
Men, those who were older, and those with diabetes (糖尿病) were significantly more likely to have high
frequency hearing loss. And this was true of those who were former smokers and those who had never
smoked. But even after taking account of these factors, both former and passive smoking were associated
with damaged hearing.
Former smokers were significantly more likely to have damaged hearing. The prevalence (流行程度) of
low to mid frequency hearing loss among this group was 14 percent. And almost half (over 46 percent) had
high frequency hearing loss. Although the risk was not as strong among those who had never smoked,
almost one in 10 (8.6 percent) had low to mid frequency hearing loss and one in four (26.6 percent) had high
frequency hearing loss.
And the stronger findings among former smokers suggested that continued passive smoking in this group,
even at low levels, could continue the progression of high frequency hearing loss that began when they were
active smokers, say the authors.
"Further research is required to determine whether passive smoking increases the effect of noise exposure
and aging on hearing," they conclude."If this finding is independently confirmed, then hearing loss can b
e added to the growing list of health consequences associated with exposure to second-hand tobacco smoke."
The study was published online in Tobacco Control. |

When you hear the word "recycling", what comes to your mind? The color green or global warming?
What if I were to tell you there is a dark side of recycling? A type of recycling that does more harm than
good. The dark side of recycling has nothing to do with the environment but rather has a lot to do with the
recycling of ideas.
Environmental unrest isn"t the only trouble we must face. Idea pollution is quickly becoming widespread
across the online world.
Think about it. When was the last time you read an original blog post? I"m guessing it has been quite a
while. Why do you think top bloggers (博主) of today win so much respect? Do you think they recycle their
ideas? With each recycled idea the online world becomes much more polluted. Used content contributes to the
ever increasing mass of digital smog (烟雾).
The first step to reduce pollution is simple: stop recycling. When you stop recycling, you will then be
forced to take up the task of creating from your own ideas. When you recycle an excellent idea, it soon
becomes good. When you recycle a good idea, it soon becomes just OK. The chain continues until the key part
of what used to make the idea good is saturated (饱和), leaving you nothing but a pile of mess.
In order not to pollute, your ideas must go beyond "just recycled". Your ideas must stand out from the
pollution of the web. For your voice and talent to be heard and seen, you must go far beyond the standard
copy of your neighbors" ideas.
For the next week, make a promise not to recycle. Let your ideas flourish and flow. Believe in your ability
to create, because the death of recycling starts with YOU. |
| 1. Which is true about top bloggers of today according to the writer? |
A. They are not worth much respect.
B. They tend to express many fresh ideas.
C. They often recycle their ideas.
D. They make good use of others" ideas. |
| 2. The 5th paragraph mainly talks about ______. |
A. how to stop recycling ideas
B. the good effects of stopping recycling
C. the bad effects of recycling ideas
D. how to recycle good ideas online |
| 3. This passage is written mainly for ______. |
A. top bloggers
B. net researchers
C. environment polluters
D. common bloggers |
| 4. The main purpose of this passage is ______. |
A. to remind people to pay attention to environmental protection
B. to prove that the web environment is becoming worse and worse
C. to call on people to write online more creatively instead of repeating
D. to warn people not to pollute our web environment with bad words |

[1] Hello. It"s one of the first words we learn as babies, yet it"s one of the last ones we think to use as
adults. That"s unfortunate, because saying hello is more than just saying hello-it is recognition of another"s
worth. How might the world change-how might we change-if we mastered this word? To find out, I spent
one month saying hello to every person I met. Here"s what I"ve learned.
[2] It can boost(促进) productivity. In one of the few studies ever done on this subject, Allan Allday, an
assistant professor of special education at Oklahoma State University, had middle school teachers greet their
students individually each morning. This exchange of greetings raised the kids" productivity. School went from
impersonal to personal, and that resulted in more class participation and better grades.
[3 ] Environments influence friendliness. One study found that people in the city were less likely to shake
hands with a stranger than those in the countryside. And, researchers say, pleasant environments generally
encourage more smiles and hellos than unpleasant ones. My experience was similar. Whatever the reason,
my urban hellos were answered far less often than my rural ones. Similarly, people in vacation spots, like the
Jersey Shore, were far friendlier than those hurrying to work downtown.
[4] It"s a form of universal health insurance. It"s impossible to say hello without smiling. And smiling has
been shown to lower blood pressure, relieve stress and boost happiness. Apparently, a smile creates a similar
effect in the recipient(接受者).
[5] So maybe we can make the world a better place by ____. After a month of doing it, I feel lighter and
more connected and I have a better sense of well-being. |

There"s no doubt that fast food has become an important part of modern life, especially among teenagers.
According to research, in the UK 80% of meals are eaten outside the home. And more than 50% of teenagers
eat, on average, more than one hamburger every three days. The percentage is high and nutritionists (营养专
家) are worried, but is fast food really as harmful as they say it is?
Here is what two experts, Jake Hyde and Ursula Birkbeck, have to say on the subject. " Fast food is junk
food," says Jake Hyde.
"Fast food is of very little nutritional value. It is full of fat, especially the harmful type, which is found in
meat, butter, cheese and mayonnaise. We need to cut down on fat if we want to stay healthy. Another thing
is that fast food contains too much salt and sugar and too many additives (添加剂 ). It is also low in vitamins
and fiber, because it includes hardly any vegetables. As a result, it doesn"t provide us with enough nutrients,
just lots of calories. Most teenagers who have made fast food an important part of their diet are overweight.
This, along with the fact that they hardly ever take any exercise, puts their health at risk. It can lead to serious
health problems like heart disease or diabetes."
"People shouldn"t feel guilty every time they have a burger," says Ursula Birkbeck." What is in it not that
bad. Don"t forget that red meat is a good source of iron and cheeseburgers (干酪汉堡包 ), for instance,
contain calcium. Chips, which most people think are unhealthy, are not so bad after all, because potatoes are
rich in Vitamin C. However, we shouldn"t eat too much sauce or mayonnaise. Nowadays, fast food restaurants
pay attention to health matters and nutrition. They have improved the quality of their food, use fewer additives,
vegetable oil for cooking and some even use low-fat products. Also, most places offer salad bars, which give
people the chance to balance fast food with vegetables that contain other nutrients. So, people don"t need to
prevent fast food from their diet completely. It"s all a matter of what type of fast food they choose to eat, how
often and what else they eat during the day." |
| 1. From the first paragraph we know that _____. |
A. it"s doubtful that fast food has become an important part of modern life
B. most meals in the UK are eaten inside the home
C. over half of the British teenagers average over one hamburger every three days
D. nutritionists are sure that fast food is very harmful |
| 2. The underlined word "mayonnaise" in Paragraph 3 is a type of ______. |
A. fat
B. food
C. meat
D. additive |
| 3. The difference of the two experts" opinions lies in ______ . |
A. whether fast food has little nutritional value
B. whether fast food is full of fat
C. whether fast food has improved its quality
D. whether fast food restaurants pay attention to health matters |
| 4. What would be the best title for the passage? |
A. Fast food-junk food
B. Fast food-friend or enemy?
C. Which expert is right?
D. The fast food restaurants are improving |

Sales of laptop computers passed desktops (台式电脑) in the US for the first time ever this fall, according
to market research firm IDC.
That" s bad news for backs, necks and shoulders.
"Laptops are basically not designed based on human bodies-unless you" re 2 feet tall," says physician
Norman J. Marcus, a muscle (肌肉 ) specialist in New York City.
When you work at a computer, the keyboard should be at elbow height, so your upper and lower arms
form an angle (角度) of 90 degrees or more. The monitor (显示器) should be at about eye level so you can
rest back in a chair with back support.
But most users simply set their laptops on a desk or table. The keyboard is too high, which makes your
arms reach up, your shoulders rise and your wrists (手腕) bend down. The monitor is too low, which pulls
your head and neck forward and down and this may hurt your back.
That" s OK if you use your laptop occasionally, for short periods. But if you use one for hours without
stopping-as do millions of college students, business travelers, video-gamers and growing numbers of office
workers-you" re setting yourself up for muscle problems that can make your entire upper body hurt.
Experts have warned about laptop problems for years-but without success. People continue to abandon
large and heavy desktops in favor of the smaller and lighter laptops. And WiFi (无线局域网 ) connections let
us use laptops anywhere-in bed, on the floor-and in all kinds of positions. |
| 1. What Norman J. Marcus says in Paragraph 3 means _____ . |
A. laptops are so badly designed
B. muscle pains are mainly caused by laptops
C. laptops are not suitable for people of usual height
D. laptops cause a lot of diseases easily |
| 2. It can be known from the passage that ______. |
A. we had better not use laptops too frequently
B. there are no suitable places for laptops
C. we shall buy desktops instead of laptops
D. desktops will face a hard future |
|
| 3. Which of the following statements can be learned from the passage? |
A. Using laptops doesn" t do harm to people" s health.
B. People pay little attention to the risks of laptop use.
C. Most people use laptops more often than desktops.
D. Laptops bring people more disadvantages than advantages. |
| 4. The main purpose of the passage is to _____ . |
A. show that laptops are widely used in the US
B. tell us people prefer laptops to desktops
C. persuade people not to use laptops any more
D. warn people of health problems caused by laptops |

United Nations warn animals important to agriculture are dying out forever. The UN Environment Program
and Food and Agriculture Organization showed us a report. The findings are based on the information collected
in 170 nations during the past ten years.
FAO officials say the world has lost about one thousand kinds of farm animals in the past one hundred years, and that 1/3 of them are at risk of disappearing. FAO officials are concerned about farmers producing enough to feed the world" s population. FAO has got the information about over 4,000 kinds of birds and animals
population. 740 of those breeds no longer exist. 1,300 others are said to be endangered or at high risk of
extinction.
Many of them are important than animals. For example, in Madagascar, Renitelo cattle have almost
disappeared. In the Philippines, the Banaba chicken is now rare. Fewer than 1,000 of the birds remain. In
Mexico, the Chiapas sheep are at the export (出口 ) of animals from industrial to developing countries. The
report says animals from industrial nations are often considered more productive in developing countries.
However, the animals are best for the environment of areas they are from. Now the UN is starting a five-year
project to help countries better understand the issue. |
| 1. Which of the following is the opposite to " extinct" ? |
A. exist
B. disappear
C. endanger
D. risk |
2. The Banaba chicken may be _____ . |

C. eaten up
D. living long |
| 3. Why are farm animals exported to developing countries? |
A. The animals are more delicious.
B. The developing countries are unable to raise animals.
C. The exported animals grow up more quickly or cheaper.
D. Some can have illness more easily. |
