We took the bus from the suburb every early morning that summer 3 years ago. One of the passengers was a small   36  man who took the bus to the centre for senior citizens every morning. He walked with a stoop (佝偻) and a sad look on his face when he, with some difficulty,   37  the bus and sat down alone behind the driver. No one ever paid very much attention to him.

　　Then one   38   morning he said good morning to the driver and smiled before he sat down. The driver 39  guardedly. The rest of us were silent. The next day, the old man boarded the bus energetically,   40  and said in a loud voice: “And a very good morning to you all!” Some of us looked up, amazed, and murmured “Good morning,”  41  . The following weeks we were more alert (留意的). Our friend was now dressed in a nice old suit and a wide out-of-date   42 . The thin hair had been carefully combed. He said good morning to us every day and we  43  began to nod and talk to each other.

　　One morning he had a bunch of wild flowers in his hand. The driver   44  smilingly and asked:“Have you got yourself a girlfriend, Charlie?”and he nodded shyly and said yes. The other passengers   45  and clapped at him. Charlie bowed and waved the   46  before he sat down on his seat. Every morning after that Charlie always brought a flower. Some of the   47  passengers began bringing him flowers for his bouquet(花束).

The summer went by, and    48   was closing in, when one morning Charlie wasn't waiting at his usual    49 . When he wasn't there the next day and the day after that, we started wondering if he was sick or —   50  — on holiday somewhere.

One day, we learned from the staff working in the centre for senior citizens that the elderly   51  was fine, but he hadn't been coming to the   52   that week. One of his very close friends had died at the weekend. They   53  him back on Monday. How silent we were the rest of the way to work.

　　The next   54   Charlie was waiting at the stop, stooping a bit more, a little bit more grey, and without a tie. He seemed to have shrinked（缩小）again. Inside the bus was a  55 . All of us sat with our eyes filled with tears and a bunch of wild flowers in our hands.

In July 1994 Jupiter, the largest planet in our solar system, was struck by 21 pieces of a comet (彗星). When the fragments (碎片) landed in the southern part of the giant planet, the explosions(爆炸) were watched by scientists here on the earth. But what if our own planet was hit by a comet?

　The year is 2094. It has been announced that a comet is heading towards the Earth. Most of it will miss our planet, but two fragments will probably hit the southern part of the Earth. The news has caused panic.

　On 17 July, a fragment, four kilometers wide, enters the Earth's atmosphere with a huge explosion. About half of the fragment is destroyed. But the major part survives and hits the South Atlantic at 200 times the speed of sound. The sea boils and an enormous(巨大的) wave is created and spreads. The wall of water rushes towards southern Africa at 800 kilometres an hour. Cities on the African coast are totally destroyed and millions of people are drowned. The wave moves into the Indian Ocean and heads towards Asia.

　Millions of people are already dead in the southern part of the Earth, but the north won't escape for long. Tons of broken pieces are thrown into the atmosphere by the explosions. As the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. Wars break out as countries fight for food. A year later civilization has collapsed(崩溃). No more than 10 million people have survived.

　Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a space fragment. The dinosaurs couldn't survive in the cold climate that followed and they became extinct. Will we meet the same end?

A. The whole world becomes extremely cold

B. All the coastal cities in Africa are destroyed

C. The visit of the comet results in wars

2.Why does the author mention dinosaurs at the end of the passage?

A. Because they could only live in the warm climate

B. Because their extinction indicates future disasters

C. Because they once dominated(控制) the earth

D. Because dinosaurs and humans never live in the same age

3. In writing the passage, the author intends to ______.

A. give an accurate description of the possible disaster in the future

B. prove that humans will sooner or later be destroyed

C. warn of a possible disaster in the future

D. tell the historical development of the Earth

4.It can be concluded that the passage is most probably part of a(n) ______.

A. article of popular science      B. news report

Many children may be fond of animals, but few ever think of making the study of animals their career(职业).Even fewer will be   1    by the whole world,   2    the title of United Nations Messenger(使者) of Peace.

But one woman has    3    all that. She has lived with chimpanzees in the African forest for more than 20 years and made great    4   .This woman is Jane Goodall. She was born in London, England, in 1934.Goodall’s lifelong    5    in animals began at an early age. By the age of 10 or 11,Goodall    6    going to Africa to live with animals. This was quite a strange dream in those days, as young    7    didn’t think of having such “wild” actions. But she was   8    by her mother. She told her that if she really wanted something, she should work hard, take advantage of   9   and never give up looking for a way.

When a close friend invited Goodall to Kenya in 1957,she readily   10   .Within a few months of her arrival she met the famous anthropologist(人类学家) Dr. Louis Leakey, who soon decided that Goodall was the    11    person he was looking for to begin a    12    of wild chimpanzees on the shore of Lake Tanganyika in Tanzania.

In July 1960, Goodall arrived at Gombe National Park in Tanzania. At the beginning, studying the chimpanzees was not    13   for her. The animals fled from her   14   , so it took months for her to get close to them. With a strong   15   , she searched the forest every day, trying not to get too close to the chimpanzees too   16   . Gradually the chimpanzees became used to her presence.

She discovered many things of chimpanzees during her first years at Gombe National Park. In October 1960,she observed a chimpanzee making and using   17    to fish for termites (白蚁).This discovery threw    18    on the popular idea at the time that Man was the world’s only toolmaker. The longer Goodall’s research continues, the more it becomes obvious that chimpanzees are very   19    to humans.

Since the mid-1980s, Goodall has been lecturing around the world to raise people’s sense about environmental    20   . “Let’s live in the new age with hope, respect for all living things, understanding and love,” she said.

One afternoon in January in 1998, Susan Sharp, 43, and her 8-year-old son David, were walking across an icy square, when Susan's cane(手杖) slipped on the ice. Her face   36   first into the mud.
