Cancer is a terrible disease. Every year...

Cancer is a terrible disease. Every year in the UK, more than 330,000 people get cancer, and doctors usually use a kind of therapy called radiotherapy to treat people. This treatment uses high energy X-rays to destroy the disease, but the effects of treatment can be nearly as bad as the cancer. As the X-rays destroy the cancer cells, they also damage healthy cells that are next to them. Its like using a shotgun to kill an insect. When really important parts of a persons body are hurt by the X-ray energy, it can have very bad results. It can also make more cancer grow in the damaged places in the future.

A new therapy that uses protons(质子) instead of X-ray energy could be the answer to the problem. In a project called PRaVDA, scientists from the UK and South Africa are working to this. If X-ray energy is like a shotgun, then protons can work more like a laser. Scientists can make protons travel through someones body without hurting them, and only damage the cancer.

The PRaVDA scientists use computers to make a 3-D model of the cancer cells to make sure the protons go to the right places. Its more accurate,” said Michaela Esposito, PhD, from the University of Lincoln.

Building this technology was very difficult, though. Professor Nigel Allinson from the University of Lincoln, the project leader, has put together a team of many different kinds of scientists with different skills. Those skills were all needed to make what he calls one of the most complex medical machines ever. Its also 10 times more expensive than X-ray radiotherapy. Even so, Allinson believes that most cancer treatment will be done by protons in the future. I think it will improve the quality of life of many cancer patients, he says.

1.What point does the first paragraph make?

A. Cancer is a really terrible disease.

B. Lots of people get cancer every year in the UK.

C. Radiotherapy isnt a perfect way to cure cancer.

D. Radiotherapy is a commonly used therapy against cancer.

2.What can be concluded about the new therapy?

A. Its much cheaper than X-ray radiotherapy.

B. It depends on protons to locate the cancer cells.

C. Damaging the cancer by replacing X-rays with lasers is much more accurate.

D. It uses protons to damage the cancer cells without damaging healthy cells.

3.According to Professor Allinson, the new therapy ________.

A. will enable cancer patients to enjoy a better life

B. will cure most cancers in the future

C. will ensure that cancer patients live longer

D. will replace radiotherapy completely

4.What can be inferred from the text?

A. Science and technology are a double-edged sword.

B. Not every cancer patient will be able to afford proton therapy.

C. Radiotherapy is completely the wrong way to cure cancer.

D. The complex medical machine mentioned will soon be put into use.

 

1.C 2.D 3.A 4.B 【解析】 试题分析:文章讲述了癌症这一顽症的最新治疗方法——质子放疗。 1.1】C 段落大意题。根据第一段中This treatment uses high energy X-rays to destroy the disease, but the effects of treatment can be nearly as bad as the cancer.可知,第一段主要讲述了癌症的一种治疗方法——放射治疗的利弊,故答案为C。 2.2】D 细节理解题。根据第二段A new therapy that uses protons(质子) instead of X-ray energy could be the answer to the problem.和Scientists can make protons travel through someone’s body without hurting them, and only damage the cancer.可知,这种新的治疗方法的好处是不会伤害健康的细胞,故答案为D。 3.3】A 细节理解题。根据最后一段中Allinson believes that most cancer treatment will be done by protons in the future. “I think it will improve the quality of life of many cancer patients,” he says.可知,Allinson教授认为这种新的治疗方法会改善癌症患者的生活质量,让他们过得更好,故答案为A。 4.4】B 推理判断题。根据最后一段中It’s also 10 times more expensive than X-ray radiotherapy.可知,这种新的治疗方法较以前的而言,昂贵了10倍,并非每个患者都能支付得起。故答案为B。 考点:考查科技类说明文阅读

Beavers(河狸) are a very unique species in the world of nature and wildlife——they are architects. Their dams are fine examples of engineering.

A pair of beavers will build a dam, using branches, mud and stones, across a river. The water held back by the dam flows over the bank on either side of the river, flooding the nearby ground and forming a pond. At some point in the pond the beavers then build their home, which is called a lodge. This consists of a cone-shaped(锥状的) pipe of branches and sticks of two to six feet in length held together with mud and stones, the top of which projects above the waterline. It serves as a shelter from the bad weather, a safety from enemies and a base for food supplies to be drawn upon in winter.

From an engineering point of view the lodge could hardly be improved. Not only does it contain a central room just above water level, which is accessible only through underwater tunnels, but it also has walls, one or more escape tunnels and an air hole at the top, which controls the temperature inside and gives air-conditioning. It is altogether a clever piece of construction, with all modern conveniences. It is, in fact, better protected against the effects of flooding than many human houses.

Trees are essential to beavers. They eat the bark on the upper branches. But they must first fell the trees, using their four front teeth. With these sharp tools, it takes only a few minutes to cut down a tree.

The engineering skill of beavers is to a large extent a result of their ability to use their front paws as hands. A female will carry her young held under her chin(下巴) with her front paws, walking on her hind legs. A similar method is used by all beavers when transporting stones or mud, although they also carry such materials on their broad flat trails. The fore-paws are also used for digging and for dragging heavier pieces of wood.

1.Which of the following pictures best illustrates the beavers lodge?

A.      B.

C.      D.

2.Which of the following sentences is Not the reason why trees are important to beavers?

A. They live on the barks on the upper branches of trees.

B. They use trees branches to build dams.

C. They build their lodge with the branches.

D. They us branches to transport mud and stones.

3.The underlined word fell in Paragraph 4 probably means ________.

A. move awayB. cut downC. cut upD. move about

4.This text is mainly about ________.

A. the beavers lodge

B. the beavers engineering skills

C. the beavers dam

D. the beavers intelligence

He met her at a party. She was outstanding; many guys were after her, but nobody paid any attention to him. After the party, he invited her for coffee. She was surprised, so as not to appear rude, she went along.

As they sat in a nice coffee shop, he was too nervous to say anything and she felt uncomfortable. Suddenly, he asked the waiter, Could you please give me some salt? I'd like to put it in my coffee.

They stared at him. He turned red, but when the salt came, he put it in his coffee and drank. Curious, she asked, "Why salt with coffee?" He explained, When I was a little boy, I lived near the sea. I liked playing on the sea. I could feel it salty, like salty coffee. Now every time I drink it, I think of my childhood and my hometown. I miss it and my parents, who are still there.

She was deeply moved. A man who can admit that he's homesick must love his home and care about his family. He must be responsible. She talked too, about her faraway hometown, her childhood, her family. That was the start to their love story.

They continued to date. She found that he met all her requirements. He was tolerant, kind, warm and careful. And to think she would have missed the catch if not for the salty coffee! So they married and lived happily together. And every time she made coffee for him, she put in some salt, the way he liked it.

After 40 years, he passed away and left her a letter which said:

My dearest, please forgive my life-long lie. Remember the first time we dated? I was so nervous that I asked for salt instead of sugar. It was hard for me to ask for a change, so I just went ahead. I never thought that we would hit it off. Many times, I tried to tell you the truth, but I was afraid that it would ruin everything.

Sweetheart, I don't exactly like salty coffee. But as it mattered so much to you, I've learnt to enjoy it. Having you with me was my greatest happiness. If I could live a second time, I hope we can be together again, even if it means that I have to drink salty coffee for the rest of my life.

Her tears made the letter totally wet. Someday, someone asked her,Whats the taste of salty coffee? Its sweet, she replied.

1.What does the writer mean by saying she would have missed the catch?

A. She meant to leave him on their first date.

B. She thought of him every now and then.

C. She nearly misunderstood his explanation.

D. She could hardly believe this simple fact.

2.Why did the man have salty coffee all his life?

A. To change lifestyle.

B. To please his wife.

C. To keep his word.

D. To remember the past.

3.The best title for the passage might be ________.

A. A Well-kept Secret
