题目内容

If you are interested in animals, you probably heard about the tragedy at Seaworld Orlando. On February 24, Tillicum, a six-ton orca(虎鲸),was performing with his trainer, Dawn Brancheau, who stood on a platform by his pool.

They had done the same show together many times before, without incident. This time, though, events took a terrible turn. Without warning, Tillicum leaped from the water, took hold of Branchcheau by her hair, and dragged her deep below the water’s surface. Before other trainers could react, Brancheau drowned.

Although known as killer whales, orcas are the largest member of the dolphin family. They are easy to train, and performances like Tillicum’s have been done safely thousands of times. Yet Dawn Brancheau’s death was a shocking reminder of what can happen when human being act together with wild animals. People began to ask, “Should orcas be kept in captivity(囚禁)”

Yes

Worldwide, only 42 orcas are being kept by humans. Scientists know very little about these huge sea animals, which are difficult to study in the wild. However, they do know that orcas are easily harmed by pollution. As our oceans become ever more damaged by human activity, observing orcas up close helps us understand them and do a better job of protecting them in nature.

“I think that some dangerous animals, such as killer whales, should be kept in captivity because it raises awareness about them and educates people about wild animals,” says Lauren, 12, a 6-grader from Colorado. “Keeping some in captivity will help protect their species.”

No

Enclosed habitats can be painful to wild animals, and make them act in unpredictable even harmful ways.

“It is wrong to keep these animals in captivity”, says Prathm, 12 The 7th grader from New Jersey, adds, “They should live in their own habitats, not be used as entertainment slaves.”

Richard Ellis, a marine conservationist in New York, agrees. “It is part of human nature to keep wild animals in small spaces and train them to do tricks,” he says. “I’m against it because I think it humiliates the animals.”

1.Why does the author tell the tragedy of Dawn Brancheau ?

A.To introduce the topic.

B.To express his sympathy.

C.To describe the human animal relationship.

D.To warn people of the danger of keeping animals.

2.What can we infer from the text?

A. It is hard to train orcas.

B. Orcas are rare sea animals.

D. Many orcas are hunted each year.

3.The underlined word ”humiliates” in the last paragraph most probably means “ _____”.

A. makes somebody less intelligent

B. makes somebody feel ashamed

C. makes somebody physically weak

D. makes somebody feel threatened

We are humans,and we all make mistakes. The mistakes that we make are not usually on purpose,whether it is breaking a vase,or not completing a task. 1. This article will provide you with ideas as to what to do once a mistake has been made.

Admit that you make a mistake as soon as you discover it. Delaying it longer will only make you feel worse,or may drive you toward making the wrong decision to try and cover it up.

2. Do not play the“blame game".Most people are smart enough to realize that this is just a poor attempt to protect yourself. Perhaps you gave a task to another person and it was never completed. But is it really the entire fault of the person you gave the task to or is it partially your fault for not following up? Keep this in mind before placing the blame on someone else.

3. Maybe you broke your mother's favorite vase,or even forgot a friend's birthday. Just an apology can sometimes be viewed as a“quick fix",and apologizing and asking to be forgiven gives the person opportunity to forgive you.

Offer some compensation(补偿)for loss,damage,or injury caused. 4. By doing this,it may soften the blow to the person we've disappointed.

Learn from your mistakes. In the case of a job or a task,write a“to-do" list with the deadline before leaving the meeting. As for forgetting a birthday,put the birthday on an electronic calendar for next year.

Do better next time. 5.We should try to understand what happened and try to make sure that it won't happen again.

A. Take responsibility.

B. Never repeat your mistakes.

C. Apologize and ask for forgiveness.

D. People’s faith in us can reduce quickly.

E. So sometimes it is necessary to write a letter to say sorry.

F. But not everyone knows how to admit making a mistake.

G. Offer to immediately complete the late task or pay for the vase.

What if handheld (掌控型的) tools know what needs to be done and were even able to guide and help inexperienced users to complete jobs that require skill? Researchers at the University of Bristol have developed and started studying a novel concept in robotics—intelligent handheld robots. Historically, handheld tools have been straight, unintelligent instruments that are unaware of the context they operate in, are fully directed by the user, and therefore, lack any understanding about the task they are performing.

Dr. Walterio Mayol-Cuevas and PhD student, Austin Gregg-Smith, from the University's Department of Computer Science, have been working in the design of the robot as well as in understanding how best to be with a tool that “knows and acts”.

Compared to other tools such as power tools that have a motor and perhaps some basic sensors (感应器), the handheld robots developed at Bristol are designed to have more degrees of freedom to allow greater independence from the instructions of the user, and importantly, understand the steps being carried out. This allows for a new level of co-operation between user and tool, such as the user providing directions and the tool performing the detailed task.

Handheld robots, aim to share physical similarity with users but are neither fully independent as is a humanoid robot nor are part of the user’s body. The aim with handheld robots is to develop the intuitiveness (灵性) of using traditional handheld tools while adding planted intelligence and action to allow for new abilities.

Dr. Mayol-Cuevas, Reader in Robotics Computer Vision and Mobile Systems, said, “There are three basic levels of autonomy (自主权) we are considering: no autonomy, semi-autonomous when the robot advises the user but does not act, and fully autonomous when the robot advises and acts even by correcting or refusing to perform incorrect user actions.”

1.What is the new concept in robotics?

A. Full control by the user.

B. Improvement in intelligence.

C. Larger size of the robots.

D. Help for the experienced users.

2.What is the meaning of the underlined word “unaware”?

A. updated B. educated

C. organized D. uninformed

3.What is the advantage of handheld robots compared to other tools?

A. They are more dependent on the users.

B. They all have a motor and basic sensors.

C. They don’t need to follow the instructions at all.

D. They have a new level of freedom to perform the task.

4.What can we learn from the passage?

A. The handheld robots can never disobey the user’s order.

B. The autonomy is the only thing that the scientists are considering.

C. There will be more intelligence and independence in the handheld robots.

D. The aim of the handheld robots is to correct and refuse the user’s directions.

The drug store was closing for the night. Young Alfred Higgins, the shop-assistant, was ready to go home. Mr. Carr, the boss, stared at him and said: “Hold on, Alfred. Maybe you'd be good enough to take the things out of your pockets and leave them here before you go.” Alfred's face got red. After a little hesitation, he took out what he had stolen. Mr. Carr said, “Maybe I should call your mother and let her know I'm going to have to put you in prison.”

Alfred thought his mother would come rushing in, eyes burning with anger. But, to his surprise, she arrived wearing a smile. “Hello, I'm Alfred's mother. Is he in trouble?” she said. Mr. Carr was surprised, too. He had expected Alfred's mother to come in nervously, shaking with fear, asking with wet eyes for a mercy for her son. But no, she was most calm, quiet and pleasant and was making Mr. Carr feel guilty…. Soon Mr. Carr was shaking his head in agreement with what she was saying. “Of course”, he said, “I don't want to be cruel. You are right. Sometimes, a little good advice is the best thing for a boy at certain times in his life and it often takes the youths long time to get sense into their heads.” And he warmly shook Mrs. Higgins's hand.

Back home, without even looking at Alfred, she said, “You are a bad luck. It is one thing after another, always has been. Why do you stand there so stupidly? Go to bed.” In his bedroom, Alfred heard his mother in the kitchen. There was no shame in him, just pride in his mother's strength. He felt he must tell her how great she was. As he got to the kitchen, he saw his mother drinking a cup of tea. He was shocked by what he saw. His mother's face was a frightened, broken one. It was not the same cool, bright face he saw earlier in the drug store. As she lifted the tea cup, her hand shook. And some of the tea splashed on the table. Her lips moved nervously. She looked very old. He watched his mother without making a sound. The picture of his mother made him want to cry. He felt his youth coming to an end. He saw all the troubles he brought his mother in her shaking hand and the deep lines of worry in her grey face. It seemed to him for the first time he had ever really seen his mother.

1.Which of the following is probably said by Mrs. Higgins while talking to Mr. Carr?

A. “Please, for God's sake, you know, he is just a kid.”

B. “I can't believe it! You are treating my son like that!”

C. “Punishment makes sense because it teaches about the law.”

D. “You know, it takes time for a youth to truly grow up.”

2.What does the underlined phrase "his mother's strength"(Para. 3) refer to?

A. Mrs. Higgins's attitude towards parental sufferings.

B. Mrs. Higgins's calmness and communicating skills.

C. Mrs. Higgins's love and care for her son Alfred.

D. Mrs. Higgins's greatness as a woman.

3.After the incident, young Alfred would probably ________.

A. change his attitudes towards life

B. feel ashamed of her mother

C. learn to live an independent life

D. hate Mr. Carr for hurting her mother

Although many Chinese students say that their knowledge of English grammar is good, most would admit that their spoken English is poor. Whenever I speak to a Chinese student, they always say, “My spoken English is poor.” 1. I would like to suggest that there may be some reasons for their problems with spoken English.

First, they fail to find suitable words to express themselves due to a limited vocabulary. 2. However, you can speak with a limited vocabulary, if you choose a positive attitude. Others will follow you as long as you use the words that you know.

_3. Sometimes they make mistakes when they are speaking because they are shy and nervous. Yet students should remember that their goal should be FLUENCY NOT ACCURACY. Your aim in writing is to be accurate following the rules for grammar and using them to get your message across. But to talk to someone in English, as quickly and well as you can, even though sometimes you may use a wrong word or tense, but it doesn’t matter. 4.

The third reason is that not enough attention is paid to listening. You have one mouth but two ears! All the hearing is necessary for you to start speaking.

Fourth, most Chinese students are reactive rather than proactive(主动的) language learners. Instead of actively seeking out opportunities to improve their spoken English they passively wait for speaking opportunities to come to them and wonder why their English always remains poor. 5.

A. Second, they are afraid of making mistakes.

B. They may try to avoid making similar mistakes next time.

C. Obviously the better answer is to expand their vocabulary.

D. However, their spoken English does not have to remain “poor”!

E. The second reason lies in the reluctance (不愿) of using what has just been learned.

F. The person you are speaking to will understand you and make allowances for any mistakes he hears.

G. If you have this proactive outlook, then you will see English opportunities wherever you go.
