A grizzly bear hunts for fish in a North American river. A mother blue whale and her calf glide through the
deep waters of the ocean.
All of these animals share the Earth with us. They fascinate us with their beauty, their grace, and their
speed. We love observing their behavior, and learning more about their habits. But just loving them is not
enough. All of these animals are endangered. Many of them have died, and without special care, they may
someday disappear from the Earth.
Why is it important to care for animals like these?One reason is to protect the balance of life on Earth.
Another reason is the beauty of the animals themselves. Each species of animal is special. Africa was once
filled with an abundance of wild animals. But that is changing fast. One of these animals, the black rhinoceros,
lives on the plains of Africa. It has very poor eyesight and a very bad temper!Even though the black rhino is
powerful, and can be dangerous, its strength can"t always help it to escape hunters. Some people think that the
rhino"s horn has magical powers, and many hunters kill rhinos for their valuable horns. This has caused the
black rhino to be placed on the endangered species list.
The elephant seems to represent all that is strong and wild in Africa. It once had no natural enemies, but is
now endangered-killed for its ivory tusks.
The fastest land animal, the cheetah, also lives in Africa. It,too, is becoming extinct as people take over
more and more of the land that is the cheetah"s natural habitat.
Imagine Africa without the powerful rhino, the gentle, intelligent elephant, or the lightning quick cheetah.
Once they are gone, they are gone forever.
B. Gone forever
C. Help animals
D. Live or die
B. Because it has a horn.
C. Because it is believed that its horn has magical power.
D. Because people think it is powerful and dangerous.
B. Beautiful birds like the great green macaw are also becoming extinct.
C. Wherever people are careless about the land, there are endangered species.
D. The elephant seems to represent all that is strong and wild in Africa.
B. Concerned.
C. Optimistic.
D. Confused.

With the development of society, unwanted sound is the most widespread nuisance (厌恶的事) in America.
But noise is more than just a nuisance. It constitutes a real and present danger to people"s health. Day and night,
at home, at work, and at play, noise can produce serious physical and psychological stress. No one escapes
being affected by this stress. Though we seem to adjust to noise by ignoring it, the ear, in fact, never closes
and the body still responds-sometimes with extreme tension, as to a strange sound in the night.
2. _____
The annoyance we feel when faced with noise is the most common outward symptom of the stress building
up inside us. Indeed, because irritability (易怒) is so obvious, legislators (立法人员) have made public
annoyance the basis of many noise limit programs. But the more unnoticeable and more serious health hazards
(harm and danger) associated with stress caused by noise traditionally have been given much less attention.
3. _____
Nevertheless, when we are annoyed or made irritable by noise, we should consider these symptoms fair
warning that other things may be happening to us, some of which may be damaging to our health. Of many
health hazards to noise, hearing loss is the most clearly observable and measurable by health professionals. The
other hazards are harder to pin down (说清). For many of us, there may be a risk that exposure to the stress of
noise increases susceptibility to disease and infection. The more susceptible among us may experience noise as
a complicating factor in heart problems and other diseases. Noise that causes annoyance and irritability in health
persons may have serious consequences for these already ill in mind or body.
4. _____
Noise affects us throughout our lives. For example, there are indications of effects on the unborn child when
mothers are exposed to industrial and environmental noise. During infancy and childhood, youngsters exposed
to high noise levels may have trouble falling asleep and obtaining necessary amounts of rest.
5. _____
Why, then, is there not greater alarm about these dangers? Perhaps it is because the link between noise and
many disabilities or diseases has not yet been conclusively demonstrated. Perhaps it is because we tend to
dismiss annoyance as a price to pay for living in the modern world. It may also be because we still think of
hearing loss as only an occupational hazard.
B. Less attention to more unnoticeable and serious hazards in spite of the most common annoyance caused by
noise.
C. The reasons for there being no greater alarm about these dangers.
D. Noise is more a real and present danger than a nuisance to people"s health.
E. How much do we know about annoyance caused by noise?
F. How much do we know about the possible hazards to people"s health caused by noise?

river in a canoe? Do you ever throw your school lunch leftovers into a compost (混合肥料) bin when you
are finished? They are all part of a regular school day at Barnard Environmental Studies Magnet School in
New Haven, Connecticut. Known as a "green" school, Barnard attracts students from all over the region who
are interested in environmental studies.
"We do Earth Day all the year round," said Marjorie Drucker, Barnard"s Magnet Resource teacher. With
the school"s special classes, its 325 students study the environment all day long. "Being green means that
everything in the building is designed with the environment in mind," Drucker told Scholastic News. For
example, the lights go off when people leave the room, and special windows provide "passive light", cutting
down on the need for electric lighting. When a window is open, the air-conditioning automatically turns off.
Conserving energy is not all that students do to help the environment. While learning about the dying
salmon population in the Connecticut rivers, students also do something to help out-they raise more salmon.
In the classrooms there are fish tanks containing salmon eggs. The eggs are kept in water at two degrees
Celsius. After the eggs hatch, students observe the baby salmon through all the stages of development, and
then release the adult salmon into Connecticut rivers.
Composting is another part of taking care of the environment at Barnard Students deal with their lunches
by throwing the remaining food into a compost bin in a greenhouse. The compost is used to help grow plants.
At Barnard, almost everything has to do with the environment. Students sing songs about the environment;
their artworks have something to do with the environment; even their math classes are focused on protecting
the environment.
Barnard offers chances that students can"t get in a regular school. The school"s goal is to teach children to
be good environmental role models. They also learn to live in a different way. To attend the school, students
have to apply and express their interest in protecting the environment. "Students come here because they care
about the environment," said Drucker.

to find out: Photograph it with a cellphone and send the image to an expert. With cellphones becoming
common in Japan and rising concern over expanding waistlines, health-care providers will allow the
calorie-conscious people to send photos of their meals to nutritionists (营养学家) for advice.
Public health insurance offices in Osaka in Western Japan have launched the service on a trial basis. About
100 cardiac (心脏病的) patients signed up in the first year, followed by diabetes and obesity patients in the
second."Japanese have been getting fatter, especially men in their 20s and 30s. There is concern over what they
learned about nutrition when they were younger," the Osaka official, Satomi Onishi, said."We"re hoping that this
program can help us deal with the problem."
Osaka is using a system developed by Asahi Kasei Corp. The system is operating among about 150
health-care providers and local governments around the country Nutritionists can work with photos from one
day"s meals to several weeks" worth. Results come back in three days. People can also log on a website to get
further information.
Dr Yutaka Kimura has developed a similar system at Kansai Medical University"s Hirakata Hospital, also in
Osaka. Five patients have taken part in the programme, which costs $37 to join and $21 per month. Patients
photograph meals over the course of three to seven days, and a nutritionist e-mails advice to them. "Patients
used to fill in meal logs, but people tend to forget things or underestimate (低估) their portions (份)," Kimura
said. "Photographing meals and e-mailing them can be easier and get more accurate results."
As Japanese have turned to bigger portions and more meat and fried foods, obesity and related illnesses
such as high blood pressure have become a rising concern. The Health Ministry estimated last year that more
than half of Japanese men and about one in five women between 40 and 70 years old were at the increased
risk of heart disease, type II diabetes and other diseases because of obesity. With the Health Ministry hoping
to see a 25% reduction in the number of people at the risk of these diseases by 2015, Osaka officials hope the
cellphone program will help.

65-year-old persons, for these young people like to listen to pop music and pop music is a kind of noise,
Besides, noise produced by jet planes or machines will make people ill or even drive them mad.
It is said a continuous noise of over 85 decibels can cause deafness. Now the government in many
