题目内容

Dogs have an amazing sense of smell thanks to 300million smell receptors in their noses, compared to only five million in the human nose. Medical dogs are trained by smelling samples of people already diagnosed with cancer and those of people without the disease so they can learn to tell the difference.

Dr Claire Guest began training her dog Daisy to smell out the killer disease in urine(小便) and breath samples（样品） when she was young. So far Daisy has found cancer in 551 patients, of which 93 per cent were accurate. And she discovered Dr Guest’s breast cancer before it was diagnosed– the first time she has discovered the disease actually growing in someone’s body, rather than by smelling a sample.

Dr Guest, 50, chief executive of charity Medical Detection Dogs, said: “She pushed against my body with her nose repeatedly – I pushed her away, but she pushed against me again, clearly upset. She pushed me so hard that it hurt me. “Her behaviour was totally out of character – she was normally such a happy dog ... I felt the tender area where she’d pushed me, and over the next few days I discovered the tiniest lump(肿块).

“If it wasn’t for Daisy it would have gone hidden for much longer and could have been more serious,” Dr Guest added. “My own pet labrador saved my life.”

Animal rescue charity Blue Cross presented Daisy with a medal for her achievements. She faced tough competition, including JJ, a bomb detection dog who has saved soldiers’ lives in Afghanistan.

Steve Goody, the charity’s deputy chief executive, said: “Cancer affects the lives of thousands of people and Daisy has made a huge contribution to the diagnosis and early treatment of cancers – she’s a very deserving medal recipient.”

Daisy is now helping to train a team of 12 dogs at Medical Detection Dogs and is a ‘senior consultant’ for the UK’s first ever trial using dogs to discover breast cancer.

1.Why was Daisy awarded a medal?

A. Because she can help discover cancer early.

B. Because she can smell the urine and breath samples.

C. Because she has saved many people’s lives by barking.

D. Because she has saved many soldiers’ lives in Afghanistan.

2.Which of the following words is closest in meaning to “recipient” in the last paragraph ________but one?

A. contributor B. ancestor C. helper D. receiver

3. How did Daisy discover Dr Guest’s cancer?

A. By smelling the urine sample.

B. By smelling the breath sample.

C. By smelling the hidden cancer.

D. By pushing Dr Guest hard.

4. From the text we can infer that __________.

A. Cancer is easy to cure.

B. Daisy and JJ competed hardly for the medal.

C. Daisy is training other dogs to discover breast cancer.

D. Dogs’ special sense of discovering cancer is highly valued.

Please don’t Hope．Decide!

While waiting to pick up a friend at the airport in Portland, Oregon, I had an experience which occurred merely two feet away from me.

Trying to locate my friend among the passengers, I noticed a man coming toward me carrying two light bags．He stopped right next to me to greet his family.

First he kissed his three children one by one and said, “It’s nice to see you．I missed you so much!” Then he hugged his wife, “I’ve saved the best for last!” giving her the longest, most passionate kiss I ever remember seeing．They stared at each other’s eyes, beaming big smiles at one another, while holding both hands．For an instant they reminded me of a couple who recently got married, but I knew by the age of their kids that they couldn’t possibly be.

Full of admiration, I asked, “Wow! How long have you two been married?” “Being together for fourteen years total, married twelve of those.” He replied, without stopping staring at his lovely wife’s face．“Well, then, how long have you been away?” I asked． “Two whole days!” “Two days?” I was surprised． By the intensity(强度) of the greeting, I had assumed he’d been gone for at least several weeks---if not months．I knew my expression betrayed me, so I turned away my eyes and murmured offhandedly(随便的，不假思索的), “I hope my marriage is still that passionate after so long!”

The man suddenly stopped smiling and looked at me straight in the eye．With forcefulness he told me something that left me a different person．“Don’t hope, friend…decide!” Then he smiled again, shook my hand and said, “God bless!”

With that, he and his family turned and went away together.

I was still watching that man and his special family walk just out of sight when my friend came up to me and asked, “What are you looking at?” Without hesitation, and with a curious sense of certainty, I replied, “My future!”

1.Which of the following statements is TRUE according to the passage?

A． The man talked with the author, with his eyes still fixed on his wife’ face.

B． After being away for several weeks, the man missed his family very much.

C． It was fourteen years since the couple had got married.

D． Their three kids reminded the author of a couple who recently got married．

2.By saying “my expression betrayed me” (in Paragraph 4), the author means that _______.

A． his expression was not faithful to him

B． he didn’t believe in his expression any more

C． the man sensed his real feelings from his expression

D． he failed to express his ideas to the man

3.From the passage, we can infer that __________.

A． the experience may be easily forgotten by the author

B． the author will live a passionate life from now on

C． the author will be away from his family and hug them passionately upon his return

D． Americans prefer to save the best for last

New Zealand is a beautiful country ________ is known for its pleasant climate and amazing scenery.

A. who B. whose C. which D. where

We all know the saying“beauty is in the eye of the beholder”, and the fact that there are a whole lot of strange—looking people out there happily loved up would suggest that it’s true．But scientists have now performed the biggest test so far，analyzing the preferences of more than 35，000 people，and have shown that we really do all have a unique “type”．

In fact，the study showed that even identical twins，who share nearly l00 percent of their DNA, aren’t attracted to the same people，suggesting that it’s our experiences，more than our genes，that determine whether we find someone hot or not．

“We estimate that an individual’s aesthetic(审美的)preferences for faces agree about 50 percent，and disagree about 50 percent，with others，’’explained Laura Germine from Harvard University，and Jeremy Wilmer of Wellesley College，lead researchers of the project．

“This fits with the phenomenon that on one hand，fashion models can make a fortune with their good looks，while on the other hand，friends can endlessly debate about who is attractive and who is not，”they added．“Of course，there are some things that people seem to find pretty much universally pleasant to look at，eg，most people prefer faces that are symmetric(对称的)．”But after analyzing the facial preferences of more than 35，000 volunteers, the researchers found that，it was experiences that seemed to be what shape the “eye of the beholder”．And those experiences are highly specific to each individual．

So in other words，it’s not your family，where you grew up，or how much money your parents make that shape who you’re attracted to，it’s things like the magazines you read, the social activities you’ve take part in，and even your first boyfriend or girlfriend，that determine these preferences．

1.What does the underlined word “identical” in Para 2 mean?

A．unique B．same

C．distinguishing D．considerate

2.Why does the writer talk about the “fashion model”?

A．To tell us they own beautiful faces which help them earn money．

B．To emphasize they have symmetric faces which people widely enjoy．

C．To show people’s preference for faces partly agree and disagree．

D．To explain the role genes play in people’s preference．

3.Which of the following statements agrees with the theme of the passage?

A．Symmetric faces look beautiful in eastern culture but not in western culture．

B．The more beautiful a person looks，the more likely he is to get a success．

C．A person’s aesthetic preferences for beauty will remain the same in the future．

D．Some think the movie star Huang Xiaoming handsome while some don’t think so．

4.What is the title of the passage?

A．Gene preference or social preference?

B．Difficult to meet every taste．

C．Beauty is in the eye of beholder．

D．Love me，love my dog?

Dear Sir/Madame,

Yours,

Whenever we turn on the TV or radio, read the newspapers, surf the Internet, we'll be surrounded by the word "diet" everywhere. We have so easily been attracted by the promise of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically（心理上地）and physically.

It's obvious that diet products weaken us psychologically. They allow us to jump over the thinking stage that our weight problems lie not in actually losing the weight, but in controlling the consumption of fat. All we have to do is to swallow or recognize the word "diet" in food labels.

What's more, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves that we don't have to work to get results．Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.

As a matter of fact, the danger that diet products bring not only lies in the psychological effects they have on us, but also in the physical harm they cause. Diet foods and diet pills contain zero calorie. oaly because the diet industry has created chemicals to produce these wonder products, And they can indirectly harm our bodies because consuming them instead of healthy foods means we are stopping our bodies having basic nutrients. Diet products may not be nutritional, and the chemicals that go into diet products are potentially dangerous.

Losing weight lies in the power of minds, not in the power of chemicals. Think twice before buying diet products. Once we realize this, we will be much better able to resist diet products, 3rd therefore, prevent the psychological and physical harm that comes from using them.

1.From Paragraph 1，we learn that

A. diet products are in our daily life

B. people have trouble choosfng diet products

C. people should put up with diet products

D. diet products are misleading people

2.The psychological effect of diet products is that people tend to

A. hesitate before they enjoy diet foods

B. pay attention to their daily diet

C. watch their weight rather than their diet

D. try out varieties of diet foods

3.The underlined part in Paragraph 3 probably means

A. diet products cause no pain

B. it costs a lot to.lose weight

C. losing weight is effortless

D. diet products are free of fat and calories

4.Diet products indirectly harm people physically because such products

A. are over-consumed B. are short of basic nutrients

C. lack chemicals D. provide too much energy
