“Well, what did I say？Buck’s a real fighter, all right,” said Francois the next morning when he discovered that Spitz had disappeared and that Buck was covered in blood．
“Spitz fought like a wolf,” said Perrault, as he looked at the bites all over Buck．
“And Buck fought like ten wolves,” answered Francois. “And we'll travel faster now. No more Spitz，no more trouble.”
Francois started to harness the dogs. He needed a new lead-dog, and decided that Solleks was the best dog that he had. But Buck jumped at Solleks and took his place．
“Look at Buck！” said Francois，laughing. “He's killed Spitz，and now he wants to be lead-dog．Go away, Buck！”
He pulled Buck away and tried to harness Solleks again．Solleks was unhappy too. He was frightened of Buck, and when Francois turned his back，Buck took Solleks’ place again. Now Francois was angry．
“I'll show you! ” he cried，and went to get a heavy club from the sledge．
Buck remembered the man in the red coat，and moved away. This time，when Solleks was harnessed as lead-dog，Buck did not try to move in．He kept a few meters away and circled around Francois carefully. But when Francois called him to his old place in front of Dave, Buck refused．He had won his fight with Spitz and he wanted to be lead－dog．
For an hour the two men tried to harness him．Buck did not run away，but he did not let them catch him．Finally，Francois sat down，and Perrault looked at his watch．It was getting late. The two men looked at one another and smiled. Francois walked up to Solleks，took off his harness， led him back and harnessed him in his old place．Then he called Buck. All the other dogs were harnessed and the only empty place was now the one at the front. But Buck did not move．
“Put down the club,” said Perrault．
Francois dropped the club, and immediately Buck came up to the front of the team．Francois harnessed him, and in a minute the sledge was moving．
Buck was an excellent leader. He moved and thought quickly and led the other dogs well. A new leader made no difference to Dave and Solleks; they continued to pull hard．But the other dogs had had an easy life when Spitz was leading．They were surprised when Buck made them work hard and punished them for their mistakes. Pike，the second dog，was usually lazy；but by the end of the first day he was pulling harder than he had ever pulled in his life. The first night in camp Buck fought Joe，another difficult dog，and after that there were no more problems with him．The team started to pull together，and to move faster and faster．
“I've never seen a dog like Buck!” cried Francois, “Never! He's worth a thousand dollars. What do you think, Perrault? ”
Perrault agreed．They were moving quickly，and covering more ground every day. The snow was good and hard，and no new snow fell．The temperature dropped to 45°C below zero, and didn't change．
This time there was more ice on the Thirty Mile River, and they crossed in a day．Some days they ran a hundred kilometers，or even more. They reached Skagway in fourteen days; the fastest time ever．The writer mentioned “the man in the red coat” in the passage to show that____.

I suddenly heard an elephant crying as though frightened. Looking down，I immediately recognized that something was wrong，and ran down to the edge of the near bank. There I saw Ma Sha with her three¬ month¬ old calf struggling in the fast rising water，and it was a life and death struggle. Her calf was floating and screaming with fear. Ma Sha was as near to the far bank as she could get，holding her whole body against the rushing water，and keeping the calf pressed against her huge body. Every now and then the rushing water would sweep the calf away.
There was a sudden rise in the water and the calf was washed clean （完全地）over the mother's body and was gone. Ma Sha turned quickly to reach it and pressed the calf with her head and trunk (象鼻) against the rocky bank. Then with a huge effort，she picked it up in her trunk and tried until she was able to place it on a narrow shelf of rock.
Just at this moment，she fell back into the river. If she were carried down，it would be certain death. I knew，as well as she did，that there was one spot (地点) where she could get up the bank，but it was on the other side from where she had put her calf.
While I was wondering what I could do next，I heard the sound of a mother's love. Ma Sha had crossed the river and got up the bank and was making her way back as fast as she could，roaring (吼叫) all the time，but to her calf it was music.The moment the author got down to the river bank he saw __________.
| A．the calf was about to fall into the river |

It’s never a real problem for us when the weather gets cold. We can put on more clothes, stay next to a fireplace, turn on the air conditioner or simply travel to a warmer city to spend the winter – people have many different ways of dealing with the cold.
But things are not as easy for plants. Unlike humans, plants can’t move to escape the cold or generate heat ( 发热) to keep themselves warm. So how do they manage to survive the freezing winter?
It turns out that plants have their own strategies （策略） too, said a study published on Dec 22 in the journal Nature.
According to researcher Amy Zanne of George Washington University, US, the cold is a big challenge for plants. Their living tissues （活组织） can be damaged when they freeze. “It’s like a plant’s equivalent to frostbite ( 相当于冻疮),” Zanne told Science Daily. Also, the process of freezing and thawing (解冻) can cause air bubbles （气泡） to form in the plant’s water transport system. “If enough of these air bubbles come together as water thaws they can block the flow of water from the roots to the leaves and kill the plant,” she explained.
To live through cold weather, plants have developed three traits （特性） , according to the study. Some plants, such as oak trees（橡树）, avoid freezing damage by dropping their leaves before the winter chill sets in – effectively shutting off the flow of water between roots and leaves – and growing new leaves and water transport cells when the warm spring returns.
Other plants, pine trees（松树） for example, protect themselves by narrowing their water transport cells, which makes it easier for cells to travel among air bubbles.
The third strategy is also the most extreme – some plants die on the ground in winter and start growing as new plants from seeds when conditions get warmer.
However, the study also found that these smart strategies were developed very slowly – over millions
of years of evolution （ 进化）. This leads scientists to worry that plants may not be able to deal with human-caused climate change, which has only started occurring over the past few decades.
Scientists are hoping that this study can help people find possible ways to save plants from the threat
of climate change.What is the article mainly about?
| A．Why plants are not afraid of the winter chill. |
| B．The ways that plants survive cold weather. |
| C．Changes in plants’ water transport system in winter. |
| D．How plants evolve to keep up with climate change. |
According to the article, if a plant freezes in the winter, ______.
| A．it produces more living tissues to stay alive |
| B．its leaves quickly fall out and its roots begin to die |
| C．lots of air bubbles form in its water transport system |
| D．its water transport system could be blocked in the spring |
What are scientists worried about when it comes to plants according to the article?
| A．Plants may not be able to adapt to the increasingly cold climate. |
| B．Human activities might have a great impact on the pace of plants’ evolution. |
| C．Plants may not be able to evolve fast enough to adapt to human-caused climate change. |
| D．The strategies plants develop are not good enough to protect them against cold. |
The old man walked with a cane (拐杖) slowly into the restaurant. His poor jacket, patched (打补丁的) trousers, and worn-out shoes made him stand out from the usual Saturday morning breakfast crowd.
He walked toward a table by the window. A young waitress watched him and ran over to him, saying, “Here, Sir. Let me give you a hand with that chair.”
Without a word, he smiled and nodded a thank you. She pulled the chair away from the table. Supporting him with one arm, she helped him move in front of the chair, and get comfortably seated. Then she pushed the table up close to him, and leaned his cane against the table where he could reach it.
In a soft, clear voice he said, “Thank you, Miss.”
“You’re welcome, Sir.” She replied. “My name is Mary. I’ll be back in a moment. If you need anything, just wave at me.”
After he had finished a hearty meal of pancakes, bacon, and hot lemon tea, Mary brought him the change, helping him up from his chair and out from behind the table. She handed him his cane, and walked with him to the front door. Holding the door open for him, she said, “Come back and see us, Sir!”
He nodded a thank you and said softly with a smile, “You are very kind!”
When Mary went to clean his table, she was shocked. Under his plate she found a business card and a note written on the napkin, under which was a $ 100 bill.
The note on the napkin read, “Dear Mary, I respect you very much, and you respect yourself, too. It shows by the way you treat others. You have found the secret of happiness. Your kind gestures will shine through those who meet you.”

We each have a unique genetic (基因的，遗传的) make-up. Every cell of your body has the same set of about 100,000 separate genes made of DNA. These are the instructions for producing a person. Genes decide everything from the colour of your skin to the way your brain works. You have one of several billion binations of DNA which e from the random(随机的，任意的) mixing of your parents’ genes. Except for identical twins (同卵双胞胎), no one has the same bination as another person. You are unique! You are unique in another way too: in the way you are raised and all the experiences you have from before birth to adult life. These experiences influence you, your behaviour and attitudes, and the choices you make.
But are genes or life experiences more important in shaping your appearance and personality? Scientists are studying twins to find out. One set of twins occurs every 70 births---some are identical and others are non-identical twins. Identical twins are special because they share exactly the same genes and often the same environment. Non-identical twins are more like ordinary brothers and sisters.
Some identical twins have been adopted and brought up in different homes. With identical genes but a different home environment, scientists can study twins to see how much a particular feature depends on the genes we inherit. For example, we know that eye problems, like short-sightedness, are mostly genetic. But resistance to pain is largely dependent on experiences. Genes also influence our eating habits. Identical twins brought up apart often like to eat at the same time of day and feel full after eating the same amount. Non-identical twins in similar circumstances have more varied eating habits. Identical twins are also more likely to follow the same patterns for marriage and divorce than non-identical twins.
Scientists are trying to identify the different genes that influence our behaviour. Some people are thrill-seekers and get into risk-taking and adventurous activities. They take up extreme sports like bungee jumping and possibly take drugs. Scientists have discovered a gene which affects this.
We could ask, “Are our lives determined by our genes or our upbringing?” Scientists are learning more all the time, but it is certainly true that both are important in making us who we are.What is the main idea of the first paragraph?
| A．We cannot easily change our physical appearance. |
| B．How we turn out depends on our parents’ genes. |
| C．Everyone has a physical double somewhere in the world. |
| D．Both our genes and our experiences make us who we are. |
Why are scientists studying twins?
| A．To find out how many twins are born every year. |
| B．To discover what shapes us as individuals. |
| C．To pare differences between twins. |
| D．To study brother-and-sister relationships. |
According to the passage, __________.
| A．one in 70 twins are genetically identical |
| B．non-identical twins are usually not of the same sex |
| C．twins separated at birth behave exactly the same |
| D．identical twins are genetically the same |
Which of the following is most affected by experience according the passage?
| A．Eating habits. | B．Eye-sight. |
| C．Pain resistance. | D．Marriage patterns. |
What does the underlined “this” in Paragraph 4 refer to?
| A．Our love of sport. |
| B．Our attitude to risk-taking. |
| C．Our skill at bungee jumping. |
| D．Our ability to take drugs. |
Why can’t some people even get an inch of what they dream of being? Blame it on pure dreaming and lack of surrounding goals for achieving their dreams.
Setting goals is very significant part of accomplishing and positive actions. It is like scaling(攀爬) a 200 feet construction and marking in the early hours on what feet you would like to reach at this specific period.
People who set goals literally generate a map of their goal settings in life, marking where they should start, where to pause, where to study a bit, and where and when to end. Once this map comes into being, it allows the map drawer to check where he is in the scheme(安排) of things and whether or not he is making some planning that will take him closer to his goals.
By surrounding goals, people will know how they are doing and what they should be doing to get their goals or dreams in life. They will know if they can relax or if they have to double their efforts when they are falling short of what is expected of them.
Goal surroundings means a person is proactive in dealing with challenges that may affect his plans. Being proactive means one is able to outline possible difficulties that may occur as well as the solutions to these difficulties. By doing this, a person is not easily scared or defeated when challenges occur because he has already prepared for them. He knows they can happen and he has prepared a solution or strategy when that time comes.
Setting goals will enable people to track their progress in whatever hard work they set out to do. It will help people bee more confident in themselves and more motivated to get their plans.The purpose of this passage is to _______________.
| A．explain the difference between the two goals. |
| B．show the importance of surrounding goals. |
| C．tell us how to set and achieve one’s goals. |
| D．tell us setting goals makes one confident. |
The underlined word “proactive” in paragraph 5 may have the closest meaning to “________”.
| A．positive | B．careful |
| C．brave | D．prepared |
According to the author, one had better ___________ in making a goal in life.
| A．take an active attitude |
| B．create a scheme as a whole |
| C．consider the possible troubles |
| D．check where he is frequently |
From the passage, we can reach the conclusion that___________________.
| A．achievements come to those who are well prepared |
| B．everyone faces the situation which is scaring or threatening |
| C．the higher one sets his goal, the more achievements he will have |
| D．success never es to people who always blame |
