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.

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."
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
B. food
C. meat
D. additive
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
B. Fast food-friend or enemy?
C. Which expert is right?
D. The fast food restaurants are improving

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.
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
B. there are no suitable places for laptops
C. we shall buy desktops instead of laptops
D. desktops will face a hard future
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.
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
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.
B. disappear
C. endanger
D. risk
2. The Banaba chicken may be _____ .
B. raised on farms
C. eaten up
D. living long
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.
B. A Five-year Project
C. The Protection of Nature

Though its number is increasing ,the Hainan deer is not yet out of the woods of endangerment. That is , it is
in great danger.
The Hainan deer, or EId"s deer, is found only in Hainan Province of South China. It looks similar to the sika
deer, but bears no plum flower spots on the body.
In the Datian Nature Reserve of Hainan the deer population has increased from 26 in 1976 to the present
500. But with the development of the island in recent years, the Hainan deer is faced with more serious
challenges to go on living.
The Datian Reserve is only 13 square kilometers in area, which is too small for the Hainan deer to find good
places or enough food.
Because more and more people have moved to the island and settled here, more land is used for building.
Weak deer which are driven out by their fellows are threatened by human neighbours. Illegal hunting is pushing
the valuable deer into difficult situation.
The Hainan deer is brown, with the female lighter in colour, and has a clear black line across the back. They
like to feed in bamboo forests, bushes and grassland under the rocks. They belong to herbivores, which feed on grass instead of meat.
From mid-January to June is the breeding season for the Hainan deer. The male deer fight against one
another with their antlers to determine the order to breed. The top winner has many more choices than the
others.
In September, the female deer start to bear fawns. The little deer follow their mothers until two years of age.
B. has no plum flower spots on the body
C. is out of the woods of endangerment
D. hasn"t increased since 1976
B. The Datian Reserve is too small.
C. Illegal hunting.
D. All of the above.
B. get enough food
C. get good places
D. get more baby deer
B. introduce us a most precious deer
C. let us know where Hainan deer live
D. warn us that the Hainan deer is endangered
knocked down. Natural resources are exhausted. That"s what makes the Galapagos Islands so special-it"s
one of the few pristine (原始状态的) places on Earth that nature can truly call its own.
For people used to having wild animals run at the scent of humans, a visit to the Calapagos is a real
eye-opening experience. Over 1,600 kms west of Ecuador (厄瓜多尔) ,the islands are home to a unique
variety of animals that have absolutely no fear of people. Visitors can play on the beach with sea lions and
giant sea turtles, swim with dolphins and whales, and get close enough to the penguins to count the eggs
in their nests.
The islands were declared a national park over 40 years ago, and the number of human visitors is tightly
limited to avoid damaging the environment or putting stress on the animals. Tourists have to pay a $100 daily
visitors fee,a nd can"t step off the boat unless accompanied (陪同 ) by an official guide. Once on the islands,
you have to stay on the trail, but that rarely presents a problem: the animals are so curious about people that
they"ll usually come up to say hello.
"It"s a little like being in a zoo," said one traveler." But instead of us looking at the animals, the animals are
looking at us.
Aside from the wildlife, one of the islands" more unusual features is its post office. You can send postcards
for free, but the catch is that there"s no postman to collect them. Instead, travelers pick up mail addressed to
people who live near them back home, and then hand-deliver the postcards when their trip is finished.
B. near Ecuador
C. in the Atlantic Ocean
D. independent of Ecuador
B. Sea lions.
C. Goats.
D. Dolphins.
B. the post office
C. the tourists
D. the guides
B. Humans and Nature
C. Go Head to Head
D. Ecuador-An Island Country
