When death came, it was silent and sudden. On the night of 21 August, 1986, a cold and mis

ty blanket of carbon dioxide gas flowed through the valleys that run down from Lake Nyos in northwest Cameroon(喀麦隆). Hugging the ground, and smothered(窒息) more than 1,700 people, many as they slept.

The region surrounding Lake Nyos is volcanic, and so sulphurous(硫磺的) volcanic gases were initially suspected as the cause of the disaster. But subsequent investigation by teams of scientists dispatched to the remote highland lake suggested that as much as 80 million cubic metres of CO2 formerly held in solution in the lake's depths, has been released explosively at its surface, such an event, called a limnic(湖泊的) eruption, had been recorded only once before-at nearby Lake Manoun, 35 kilometers from Lake Nyos. That eruption, which killed 37 people in 1984, was kept secret at first, as the Cameroonian authorities had suspected terrorist involvement.

Expeditions to Lake Nyos since the 1986 disaster have allowed researchers to unravel(拆开) the geological process that underlie the lake's lethal tendencies. Armed with this information, a small group of scientists and engineers-funded to the tune of $450,000 by the Office of US Foreign Disaster Assistance, with additional help from the French and Cameroonian governments arrived in the area in January to attempt to 'degas' the lake, and so prevent it killing again. The plan is simple—the limited budget and the lack of decent roads into the region mean it has to be. The team will lower a length of high-density polyethylene pipe deep into the lake and pipe CO2 rich water towards the surface, where the gas can bubble out on a controlled way.

Most experts agree that degassing the lake is a good idea. But some say there is a small chance that the effort could trigger another limnic eruption and lives at risk. Although villagers surrounding Lake Nyos have been evacuated(撤退) to avoid a repeat of the 1986 catastrophe, farmers and their livestock still venture into the area, lured by its lush pastures.

Why was the death regarded silent？

A．Because it's quiet after an explosion.

B．Because the people were killed outright.

C．Because when it came, the victims were in sleep.

D．Because it happened suddenly.

听力原文： Abraham Lincoln was born in a log cabin in Kentucky on February 12, 1809. When he was a small boy, his family moved to file frontier of Indiana. Here, his mother taught him to read and write.

When Lincoln was a young man, his family moved to the new state of Illinois. Lincoln had to earn a living at an early age, but in his leisure time he studied law. He soon became one of the best known lawyers in the state capital at Springfield, Illinois. It was here that Lincoln became famous for his debates with Stephen A. Douglas on the subject of slavery.

In 1860, Lincoln was elected President of the United States. He was the candidate of the new Republican Party. This party opposed the creation of new slave states. Soon after his election, some of the Southern states withdrew from the Union and set up the Confederate States of America. This action brought on the terrible Civil War which lasted from 1861 to 1865.

On January 1, 1863, during the war, Lincoln issued his famous Emancipation Proclamation. In 1865, after the war ended, the Thirteenth Amendment was added to the Constitution of the United States. This amendment put an end to slavery everywhere in the United States.

Early in 1865, the Civil War came to an end with the defeat of the South by the North. Only a few days after the end of the war, Lincoln was shot by an actor named John Wilkes Booth. The President died on April 14, 1865. In his death, the world lost one of the greatest men of all time.

A．In 1809.

B．In 1863.

听力原文： "Loving a child is a circular business. The more you give, the more you get, the more you went to give." Penelope Leach once said. What she said proves to be true of my blooded family. I was born in 1931. As the youngest of six children, I learned to share my parents' love. Raising six children during the difficult times of the Great Depression took its toll on my parents' relationship and resulted in their divorce when I was 18 years old. Daddy never had very close relationships with his children and drifted even farther away from us after the divorce.

Several years later a wonderful woman came into his life, and they were married. She had two sons, one of them still at home. Under her influence, we became a "blended family" and a good relationship developed between the two families. She always treated us as if we were her own children. It was because of our other mother—Daddy's second wife-that he became closer to his own children. They shared over twenty-five years together before our father passed away. At the time of his death, the question came up of my mother—Daddy's first wife—attending his funeral. I will never forget the unconditional love shown by my stepmother when I asked her if she would object to Mother attending Daddy's funeral. Without giving it a second thought, she immediately replied, "Of course not, Honey. She's the mother of my children."

(30)

A．Family violence.

B．The Great Depression.

C．Her father's disloyalty.

D．Her mother's bad temper.

Darwin's great work, The Origin of Species, is now generally accepted as one of the most i

mportant books ever written. But when it first came out in 1859, it was both derided and bitterly condemned by scientists and laymen.

Much of opposition to The Origin of Species arose from Darwin's claim that all living creatures, including man, are somehow related. Many people were outraged by the suggestion that man shared a common ancestor with animals such as apes and monkeys. They attacked Darwin for saying that man had descended from the apes.

But Darwin never actually said this. He believed that modern men and modern apes have both descended from the same ancestor. But at some time in pre-history, millions of years ago, men and apes began to develop separately, and ever since have continued to take on different characteristics. Today, more than 90 years after Darwin's death, this is the opinion which scientists continue to hold.

In his works, Darwin described the progression of life from its earliest forms. First came the invertebrate-creatures without a backbone. Then invertebrates evolved into fish; fish into amphibians; amphibians into reptiles; and reptiles into birds and mammals.

Fossil remains found after his death show that Darwin was right. Perhaps the most amazing fact about his theory is that he managed to work it out with the aid of only a few fossil discoveries.

Fossil remains were not the only information which we now possess but which Darwin lacked. He did not know that apes have the same diseases as men; nor that they and men have the same kind of blood. Nor did he know about the modern uses of radiation which enable scientists to tell the age of fossil remains and so estimate the speed at which evolution has taken place.

Which of the following best describes the passage as a whole？

A．The Origin of Species is a very significant book.

B．Darwin's discoveries were proved to be right though the Origin of Species was severely attacked.

C．The evolution of men has gone through a very long process.

D．It was impossible for Darwin to prove his ideas only with the aid of fossils.

Have you ever suddenly felt that someone you know was in trouble-and he was？ Have you ever

dreamed something that came true later？ Maybe you have ESP(超感官知觉).

ESP stands for Extra Sensory Perception. It may be called a sixth sense. It seems to let people know about events before they happen, or events that are happening some distance away.

Here is an example: A woman was doing washing. Suddenly she screamed. "My father is dead! I saw him sitting in the chair!' Just then, a telegram came. The woman's father had died of a heart attack. He died sitting in a chair.

There are thousands of stories like this on record. Scientists are studying them to find out what is behind these strange mental messages. Here's another example--one of hundreds of dreams that have come true.

A man dreamed he was walking along a road when a horse and carriage came by. The driver said, "There's room for one more." The man felt the driver was Death, so he ran away. The next day the man was getting on a crowded bus. The bus driver said, "There's room for one more." Then the man saw the driver's face was the same face he had seen in the dream. He wouldn't get on the bus. As the bus drove off, it crashed and burst into flames. Everyone was killed!

Some people say stories like these are lies or coincidences. Others, including some scientists say that ESP is true. From studies of ESP, we may some day learn more about the human mind.

ESP lets people know about

A．their dreams

B．events after they happen

C．events before they happen

From【M3】______ now on, though, western eyes, missing the global picture, saw the【M4】______ trouble going into decline. With occasional breaks for war, the rates of death and infection in the Europe and America dropped steadily【M5】______ through the 19th and 20th Centuries. In the 1950s,the introduction of antibiotics strengthened the trend in rich countries, and the antibiotics were allowed to be imported to poor countries. Medical researchers【M6】______ declared victory and withdrew. They are wrong. In the mid-1980s the frequency of infections【M7】______ and deaths started to pick up again around the world. Where tuberculosis vanished, it came back; in many places where it had【M8】______ never been away, it grew better. The World Heath Organization【M9】______ estimates that 1.7 billion people(a third of the earths population) suffer from tuberculosis. Even when the infection rate was falling, population growth kept the number of clinical cases more or less constantly at 8 million a year. Around 3 million of those people【M10】______ died, nearly all of them in poor countries.
