people choose to live close together in cities, the waste-disposal problem becomes increasingly difficult.
During the eighteenth century, it was usual for several neighboring towns to get together to select a
faraway spot as a dump site. Residents or trash haulers (垃圾托运者) would transport household
rubbish, rotted wood, and old possessions to the site. Periodically (定期的) some of the trash was
burned and the rest was buried. The unpleasant sights and smells caused no problem because nobody
lived close by.
Factories, mills, and other industrial sites also had waste to be disposed of. Those located on rivers
often just dumped the unwanted remains into the water. Others built huge burners with chimneys to deal
with the problem.
Several facts make these choices unacceptable to modern society. The first problem is space. Dumps, which are now called landfills, are most needed in heavily populated areas. Such areas rarely have empty
land suitable for this purpose. Property is either too expensive or too close to residential neighborhoods.
Long-distance trash hauling(垃圾托运) has been a common practice, but once farm areas are refusing to
accept rubbish from elsewhere. Cheap land within trucking distance of major city area is almost
nonexistent.
Awareness of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers,
ground water, land and air is a price people can no longer pay to get rid of waste. The amount of waste,
however, continues to grow.
Recycling efforts have become commonplace, and many towns require their people to take part.
Even the most efficient recycling programs, however, can hope to deal with only about 50 percent of a
city"s reusable waste.

Falling leaves, whithering flowers, cold winds, faint sunshine. 1 Spirits can be low.
People who suffer from "the autumn blues" often are extremely exhausted, lack energy, need more
sleep, feel increased appetite and gain weight.
"The exact cause of this condition, often called seasonal depression or seasonal affective disorder
(SAD), is not known yet," says Chen Jue, associate professor at Shanghai Mental Health Center. "But
recent studies indicate that weather change is influential and strongly suggest that this condition is caused
by changes in the availability of sunlight."
One theory is that with decreased exposure to sunlight, the biological clock that regulates(调节)
mood, sleep, and hormones is delayed, running more slowly in winter. 2 Another theory is that brain
chemicals that transmit information between nerves may be altered(改变) in individuals with SAD. It is
believed that exposure to light can correct these imbalances.
" 3 Remember, spring always lives in your heart." Chen says.
Here are some tips to deal with autumn depression.
1.Go outdoors and get some sunlight. More around. Fresh air and exercise improve the respiratory
( 呼吸) system and blood circulation and regulate the nerves system. Thus, exercise is calming and
relieving one"s mood.
2.Relax at work. Stretch, breathe deeply. Take a tea break. Think of your next vacation.
3. 4 Chocolate and sugar raise the spirits.
4. Look at bright colors, such as red and orange.
5. 5 Blooming plants are cheering
6.Call friends or family when you feel lonely or depressed. Recall some happy memories.
A.Exposure to light may reset the biological clock.
B.Decorate your room and work space with flowers.
C.It is a sad season, but you can try to make it happy.
D.That is the way you can use to lighten yourself.
E.Keep a chocolate bar in your pocket.
F.For many people, late autumn can be a season of gloom and depression.
G.Autumn always gives us a beautiful scene.

| Carbon monoxide(一氧化碳) poisoning kills and injures many people and animals around the world. The gas has been a problem since people first began burning fuels to cook food or to create heat. It is a problem in all parts of the world that experience cold weather. Carbon monoxide is called the silent killer because people do not know it is in the air. The gas has no color. It has no taste. It has no smell. It does not cause burning eyes. And it does not cause people to cough. But it is very deadly. It robs the body of its ability to use oxygen. Carbon monoxide decreases the ability of the blood to carry oxygen to body tissues. It does this by linking with the blood. When the gas links with the blood, the blood is no longer able to carry oxygen to the tissues that need it. Damage to the body can begin very quickly from large amounts of carbon monoxide. How quickly this happens depends on the length of time a person is breathing the gas and the amount of the gas he or she breathes in. Carbon monoxide poisoning has warning signs. But people have to be awake to recognize them. Small amounts of the gas will cause a person"s head to hurt. He or she may begin to feel tired. The person may feel sick. The room may appear to be turning around. The person may have trouble thinking clearly. People develop severe head pain as the amount of gas continues to enter their blood. They will begin to feel very tired and sleepy. They may have terrible stomach pains. Medical experts say carbon monoxide affects people differently. For example, a small child will experience health problems or die much quicker than an adult will. The general health of the person or his or her age can also be important. An older adult with health problems may suffer the effects of carbon monoxide more quickly than a younger person with no health problems. People with heart disease may suffer chest pains. They may begin to have trouble breathing. | |||

| Songs that make our hearts happy can make them stronger too, US researchers reported on Tuesday.They found that when people listened to their favorite music, their blood vessels (血管) dilated in much the same way as when they are laughing, or taking blood medications. "We have a pretty impressive effect," said Dr Michael Miller, director of preventive cardiology (心脏病学) at the University of Maryland Medical Center in Baltimore. "Blood vessel diameter improved," he said. "The vessel opened up pretty significantly. You can see the vessels opening up with other activities such as exercise." A similar effect is seen with drugs such as statins. When blood vessels open up more, blood flows more smoothly and is less likely to form the clots (凝块) that cause heart attacks and strokes. "We are not saying to stop your statins or not to exercise but rather to add this to an overall program of heart health," said Miller, who presented his findings to a meeting of the American Heart Association in New Orleans. Miller"s team tested 10 healthy, non-smoking men and women, who were told to bring their favorite music. They spent half an hour listening to the recordings and half an hour listening to music they said made them feel anxious while the researchers did ultrasound tests designed to show blood vessel function. Compared to their normal baseline measurements, blood vessel diameter increased 26 percent on average when the volunteers heard their joyful music. Listening to music they disliked - in most cases in this group heavy metal - blood vessels narrowed by six percent, Miller said. Miller said he came up with the idea after discovering that laughter caused blood to literally flow more smoothly. "I asked myself what other things make us feel really good, besides calories from dark chocolate of course. Music came to mind. ... It makes me feel really good," he said. Most of the volunteers chose country music but Miller said the style is not so important rather than what pleases each individual. | |||
| 1. The underlined word dilate (in Paragraph 2) is closest in meaning to "_____". | |||
| A. widen B. move C. change D. increase | |||
| 2. According to the passage, which of the following will NOT cause blood vessels to open up? | |||
| A. Taking exercise. B. Listening to unpleasant music. C. Bursting into laughter. D. Taking drugs like statins. | |||
| 3. It can be inferred from the passage that _____. | |||
| A. blood clots are caused by heart attacks and strokes B. music is better than chocolate for your health C. the style of music has different effects on different people D. a person"s overall health is more influenced by how much exercise he gets | |||
| 4. What is the passage possibly taken out from? | |||
| A. A scientific journal(杂志). B. A school textbook. C. A medical brochure(手册). D. A local newspaper. | |||
| 5. What"s the best title of the passage? | |||
| A. Pleasant Music Cures B. Research into Blood Vessel C. Music and Heart Attack D. Music and Happiness | |||

| TUVALU, a tiny country in the Pacific Ocean, has asked for help as it fears it will be swallowed up by the sea. Storms and huge waves are a constant threat and none of Tuvalu"s nine little islands is more than five meters above sea leavel, Salt water is already entering the country"s drinking water supply, as wel l as damaging plants that produce fruit and vegetable. 1___________ 2____ __. Venice, a historic city in Italy best known for its canals, has sunk about 24 cm over the past 100 years. Experts say that it will have sunk another 20-50cm by 2050. A century ago, St. Mark"s Square, the lowest point in the city, flooded about nine times a year, Nowadays, it happens more that 100 times. While Venice is slowly sinking into the mud on which it stands, Tuvalu"s rising sea level is caused by global warming. The average global temperature has increased by almost 0.5 centigrade degrees over the past century; scientists expect it to rise by extra 1-3 degrees over the next 100 years. Warmer weather makes glaciers(冰川)melt, adding more water to the ocean.The warmer temperatures also make water expand, so it takes up more space, causing the sea level to rise. The sea level has risen about 10－25 cm in the last 100 years. 3______. Through burning coal, oil and gas, people have been increasing the greenhouse gases in the atmosphere, such as CO2. This adds to the powe  r of the greenhouse effect, making the planet even warmer.Many scientists believe that, if the warming is not stopped, there will be huge climate changes. 4______5_______, the sea will swallow up millions of homes and the world will be flooded with "climate refugees" looking for somewhere to live. | |||
| A. The main cause of global warming is human pollution B. Should this come true C. Without urgent help, the country"s days are numbered. D. But Tuvalu is not the first place to face sinking into the sea E. The sea level could rise by one meter this century F. people face a lot of pollution G. much has been done about our planet |
