高三英语单项填空简单题查看答案及解析

People who are worried about bad breath often reach for a toothbrush or a gun. But in the future, personal breath monitoring may include far more than fresh breath.

In face, breath is so rich in chemical compounds that fully understanding it has proved challenging. Each breath contains gases like carbon dioxide, the volatile(挥发性的)remains of recent snacks, medicines and even compounds taken in from things like carpeting or various kinds of air pollution. But breath detectors(检测器) can sort out these substances with increasing sensitivity(敏感性)。

Scientists are building electronic sniffers that examine the exhaled(呼气)air for signs of cancer, asthma(哮喘), and other diseases.

“There are clear signatures in the breath for liver(肝)disease, kidney(肾)disease and heart disease. Breath is a rich mixture that can reflect out state of health and disease.” said Dr. Raed Dweik, director of the Cleveland Clinic, adding “Breath analysis is the future of medical testing.”

He and his partners are testing a desktop system called BreathLink for use in rapid identification of diseases. The system is designed to work wherever there is an Internet connection. To use BreathLink, a person breathes into a long tube, and a breath sample is collected and analyzed within the system. Then it can detail chemical concentrations(浓度)of the breath in graphics. Dr. Raed Dweik said, “If you examine patients of asthma, you will find they have higher levels of nitric oxide(一氧化碳) in their exhaled air. It reflects their abnormal symptoms in the lungs.” His tests have reached 85 percent accuracy(精确度)so far in spotting people with some illness.

But some trained dogs, he pointed out, can sniff out cancer with 99 percent accuracy—although without the ability to identify particular compounds the way some detectors can.

“We are getting better and better,” he said. “But whether we will ever approach the accuracy of the dog—we don’t know.”

1.What is the breath detector used for?

A. To find what kind of disease a person has.

B. To identify substances from people’s breath.

C. To help a patient recover from disease.

D. To smell how bad the breath is.

2.In the fifth paragraph, what Dr. Raed Dwik said is meant to______.

A. show how he and his partners treated patients

B. tell why a person has asthma

C. show how sensitive the device is

D. show how to diagnose a patient of asthma

3.It can be inferred that_______

A. brushing teeth can improve one’s bad breath

B. there are leftovers like snacks and medicines in one’s breath

C. one can know exactly about his physical state through the breath

D. breath analysis can be helpful in medical diagnosis

4.What’s the author’s attitude towards the future of breath detectors?

A. Indifferent　　　　 B. Positive

C. Doubtful.　　　　 D. Critical.

A troubled young man in Connecticut laid his hands on the kinds of guns that no civilian should ever have and shot 20 children and 6 adults . It was a tragedy that “ broke the hearts of America ” , as President Barack Obama said . The obvious way to prevent the next such massacre is gun control . And , yes , we need it now . Voters need to be loud , politicians need to be brave , and the gun lobby needs to be defeated . Perhaps Barack Obama , no longer up for election , will no longer be chicken .

But American violence doesn’t just come from the weapons we buy and the gun shows we frequent . It’s much deeper than that . This is also the country that supplies three-quarters of the world’s arms trade . These are weapon sales authorized by our government and by a Democratic President .

Every more they are identified with womanliness , too . The most popular video game this week is “ Halo 4 ; ” the most popular novel is Tom Clancy’s “ Treat Vector ; ” the second and s\third best-selling works of nonfiction are “ Killing Kennedy ” and “ Killing Lincoln , ” respectively . Every author , and every creator , should have the right to make what they want . Still , every civilian has a right to choose what to see and what to buy .

Violence is sometimes essential to art , and often to foreign policy , too . But the cruel killing in Newtown , the worst single event in this country in eleven years and three months , should lead to a moment of deep reflection . It’s time to talk about guns ; but it’s also time to talk about a lot more .
