When I was a boy, I belonged to the Boy Scouts(童子军)，so I used to go camping every summer, and once something happened which I have never been able to explain.
We were camping in a place above a river. After arriving, we all rushed down to the river and had a swim. Standing by the river, we noticed that it was surrounded by cliffs (悬崖).If someone wanted to reach the river at this point, he had to walk past our camp.
Several days later, the scoutmaster had to be away for a day. That afternoon, we had supper early. We were sitting round the fire, eating and talking, when a man walked past and went down towards the river. We all felt that this man looked very strange, but, because each of us was afraid of looking very stupid, no one said anything.
We ate rather slowly, taking as long as possible. After finishing, we collected our plates together so that we could take them to the river where we always washed them. But no one moved towards the river, we stood looking at each other ashamed. Then all shouting at once, we began talking about the man who had walked past us. We agreed how strange he looked and we wondered what he could be doing by the river. We knew that he could only return by passing through our camp.
An hour passed. Then one of the boys suggested we should creep(悄悄移动)down by the river so that we could see what the man was doing. Moving very slowly and keeping in the shadow, we crept down towards the bank. One boy climbed a tree so that he could see everything clearly. He called to us that there was no one there, so we ran down to the bank, looking everywhere carefully. We could not understand where the man had gone.
When it got dark, we went back to our camp feeling bewildered. We told the scoutmaster what had happened in the evening. Smiling, he doubted that we had seen the man, but finally suggested we go and look again. We did, but there was no one there.

WELLINGTON, September 19 (Xinhua) -- If your teenage son won't get out of bed in the morning, then take comfort from the fact that he might be sleeping his way to a healthier future, according to a new research from New Zealand.
Researchers in human nutrition at the University of Otago have found that teenage boys who sleep less have more body fat when compared to girls, for whom lack of sleep has no noticeable effect on their body fat ratios.
The study of 386 boys and 299 girls aged 15 to 18 found that average-sized 16-year-old boy weighing 69.5 kg and 176 cm tall, who slept for eight hours a day, had a waist size l.8 cm bigger and l.6 kg, or 9 percent, more body fat than the average-sized boy who slept 10 hours a day.
"The boys who slept eight hours a day would also have l.8 kg more lean (bone and muscle) mass compared to the boys who slept 10 hours, but that's only a 1.4-percent increase, compared to the 9- percent increase seen in body fat," said lead researcher from the Department of Human Nutrition, Dr. Paula Skidmore.
"Our results suggest that for older teenage boys, making sure that they get enough sleep may help to maintain a healthier body. It seems to be that, within reason, the more sleep the better for boys," Skidmore said in a statement Thursday.
"It was unexpected that we did not find the same result in girls, who may actually be more aware of their diet and more in tune with a healthier lifestyle."
The researchers ruled out the effects of food choice and number of screens, such as televisions, games and consoles, which the teenagers had in their bedrooms.What's the research really about?
| A．Boys and girls. | B．Food and weight. | C．Sleep and health. | D．Screens and fat. |
What's the result of less sleep for teenage boys?
| A．Bigger waist and more fat in the body. |
| B．An increase in weight and height. |
| C．More concerned with their diet. |
| D．A decrease in bone and muscle. |
From the sixth paragraph we can infer that ______.
| A．girls usually sleep less and have healthier lifestyles than boys |
| B．the researchers expected to see the same result in girls |
| C．peoples' diet has a great effect on their health |
| D．boys are usually lazier than girls |
Who would be the most pleased to hear the news?
| A．Teachers. | B．Girls. | C．Parents. . | D．Boys. |
Back in old times, people had little knowledge about the universe and nature. Things we now consider to be common sense were mysteries to our ancestors.
Over the years, major breakthroughs have been made in science and many phenomena have been explained. But still, there are always questions we can't yet answer, and The Guardian has listed some of them.
1. What makes us human?
Just looking at your DNA won't tell you - human DNA is 99 percent identical to that of the chimpanzee and, believe it or not, 50 percent identical to a banana's! A lot of the things we once thought were unique about us - language and tool use, recognizing ourselves in the mirror and so on – have since been seen in other animals. Perhaps it's our culture that makes the difference or maybe our ability to use fire. It's also possible that our capacity (能力) for co-operation and our trading skills are what make us unique.
2. Why do we dream?
Given the fact that we spend around a third of our lives sleeping, shouldn't we know everything about it? Unfortunately, scientists are still searching for a complete explanation of what happens when we sleep and why we dream.
Austrian psychologist Sigmund Freud believed dreams were the expressions of wishes that we can't fulfill in our real lives. Others have wondered whether dreams are just random "noise" coming from a sleeping brain.
3. Could we someday live forever?
Apart from accidents, most people die because of diseases that can be treated and aging. And since many diseases, such as diabetes（糖尿病） and cancer, are diseases of aging, treating aging itself could be the key to extending our lives.
Our knowledge of what causes us to age - and what allows some animals to live longer than others - is expanding rapidly. And though we haven't quite worked out all the details, we've worked out some pieces of the puzzles such as DNA damage and metabolism (新陈代谢), which are all leading to the invention of drugs that can slow down the aging process.
If we're lucky enough to lengthen our lives, we might even get to see the day when all of these questions are answered.The main point of the passage is ______.
| A．to inform people of the knowledge about the universe and nature |
| B．to introduce major breakthroughs that have been made in science |
| C．to present some questions we can't yet answer |
| D．to explain what were once mysteries to our ancestors |
Chimpanzees and bananas are mentioned as examples to prove that ______.
| A．human beings are actually not different from other animals |
| B．animals have completely different DNA from that of plants |
| C．both animals and plants share the same amount of DNA |
| D．DNA alone is not good enough to make humans different |
The underlined word "identical" is closest in meaning to ______.
| A．mysterious | B．unique | C．advanced | D．same |
Which of the following statements is TRUE according to the passage?
| A．What were mysteries to our ancestors are considered to be common sense now. |
| B．Now we know much more about dreams than our ancestors did in the past. |
| C．With the invention of new drugs people can possibly live even longer. |
| D．If all the diseases can be treated people can theoretically live forever. |
One day, when I was a freshman in high school, I saw Kyle from my class walking home from school. It looked like he was carrying all of his books. I thought to myself, "Why would anyone bring home all his books on a Friday? He must really be a nerd (a foolish person)." I had quite a weekend planned, so I shrugged my shoulders and went on.
As I was walking, I saw a bunch of kids running towards him. They knocked all his books out of his arms and tripped(绊倒) him so he landed in the dirt. His glasses went flying, and I saw them land in the glass about ten feet from him. He looked up and I saw this terrible sadness in his eyes. So, I jogged over to him and as he crawled around looking for his glasses, I saw a tear in his eye.
As I handed him his glasses, I said, "Those guys are jerks. They really should go to hell." He looked at me and said, "Hey, thanks!" There was a big smile on his face. It was one of those smiles that showed real thankfulness. I asked him where he lived. As it turned out, he lived near me.
Over the next four years, Kyle and I became best friends. I teased him all the time about being a nerd. He had to prepare a speech for graduation. As he started his speech, he cleared his throat, and began. "Graduation is a time to thank those who helped you make it through those tough years. I am here to tell you a story."
I just looked at my friend with disbelief as he told the story of the first day we met. He had planned to kill himself over the weekend. He talked of how he had cleaned out his locker so his Mom wouldn't have to do it later and was carrying his stuff home. He looked hard at me and gave me a little smile. "Thankfully, I was saved. My friend saved me from doing the unspeakable."
I heard the gasp(倒吸气) go through the crowd as this handsome, popular boy told us all about his weakest moment. I saw his Mom and Dad looking at me and smiling that same grateful smile. Not until that moment did I realize its depth.Why did Kyle carry all his books home?
| A．Because it was Friday. |
| B．Because he was a nerd. |
| C．Because he wanted to kill himself. |
| D．Because he liked doing things for his mother. |
Which of the statements is TRUE according to the passage?
| A．The bunch of kids attacked Kyle to have his glasses and books. |
| B．The author planned to study all weekend after he met Kyle. |
| C．The author was a freshman when Kyle gave the speech. |
| D．Kyle felt grateful to the author for his help. |
What can we infer from the passage?
| A．When Kyle couldn't find the glass, he turned to the author for help. |
| B．The author teased Kyle a lot about being a nerd. |
| C．The author didn't expect Kyle to tell the story. |
| D．Kyle thanked his parents first for saving his life. |
What does the underlined "them" in the 2nd paragraph refer to?
| A．The kids. | B．Kyle's books. | C．Kyle's glasses. | D．Kyle's arms. |

Australia is sometimes called “the lucky country”. One reason is the wonderful riches under the earth: gold, silver, iron, coal and many other precious metals. Oil and natural gas have helped to build big industries. Victoria, the southeastern state, has a large number of industries. Oil is no problem for them. The Bass Strait, off the coast of Victoria, has been one of the country's biggest oil fields for many years.
South Australia is the driest of all the states, but it does have the Murray River. The river brings greenness and life to the state's southeast corner. In the early days of Australian history, the Murray River was South Australia's main road. Before real roads and railways came, the river carried people and goods from the coast up into the country. Some towns on the Murray still keep the old riverboats, and visitors can ride on them. People sometimes call Australia “the lucky country”, because ____ .
| A．the people in Australia are very lucky |
| B．Australia has a large number of industries |
| C．there is the biggest oil fields of the world |
| D．the country has very rich natural resources |
What do you think of South Australia?
| A．It's a scene of desolation（荒凉）. | B．It's a scene of desert. |
| C．The land is full of life. | D．The land lies waste. |

a．It lies in the south of the country.
b．It is the largest river of the country.
c．It irrigates the driest of the country.
d．It brings greenness and life to the southeast corner.
e．It is still an important passageway to carry people and goods.
| A．a, b, c and d | B．b, c, d and e | C．c, d, e and a | D．d, e, a and b |
