试题【Most American children eat potatoes every day, but they don"t know which part of】；主要考察你对题材分类等知识点的理解。[详细]
举一反三
If health issues arise from cell phone use, the possible effects are huge. Voice calls - Americans chat on cell phones 2.26 trillion(万亿)minutes annually - earn $109 billion for the wireless carriers.
Devra Davis, an expert who has worked for the University of Pittsburgh, has published a book about cell phone radiation, “Disconnect.” The book surveys scientific research and concludes the question is not settled.
Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cell phones arrived. But the average masks an increase in brain cancer in the 20-to-29 age group and a drop for the older population.
“Most cancers have multiple causes,” she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer.
Children are more vulnerable（易受伤的）to radiation than adults, Ms. Davis and other scientists point out. Radiation that penetrates only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid（易吸收的液体）. No studies have yet been completed on cell phone radiation and children, she says.
Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiation had damaged DNA in their brains.
Ms. Davis recommends using wired headsets or the phone’s speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the abdomen（腹部）.
小题1:According to Ms Davis, brain cancer increase ____.
| A．among children | B．among old people |
| C．in the twenties | D．among pregnant women |
| A．Because they haven’t grown up. |
| B．Because they are too young to protect themselves. |
| C．Because they use cell phones more often than adults. |
| D．Because their skulls are thinner and their brains are easily hurt. |
| A．Pregnant women should keep cell phones away. |
| B．People should use cell phones in the correct way. |
| C．If you are a child, you’d better text than make phone calls. |
| D．When you use a cell phone, use a wired headset or the phone’s speaker. |
| A．Be careful when using cell phones. |
| B．Don’t hold your cell phone against your ear. |
| C．Rats exposed to radiation have damaged DNA in their brains. |
| D．Low-energy radiation could damage cells that could lead to cancer. |
Last Thursday, however, a group of doctors asked the government to remove milk from the lunch program. The Physicians Committee for Responsible Medicine (PCRM) says, “Milk is high in sugar, high in fat and high in animal protein, all of which have negative effects on health.” “One of the only reasons people talk about dairy, or promote it, is that it is going to help build strong bones.” says Dr. Neal Barnard, president of the PCRM. There are better and healthier ways to get calcium such as eating beans, broccoli, cereals and tofu. Orange juice and soymilk that have calcium added to them also supply the nutrient.
Of course, calcium is important for healthy bones and teeth, but your genes, how much vitamin D you take in and getting an hour’s worth of exercise every day all play a part.
Some nutritionists disagree with the idea that milk isn’t important. Keri Gans, a dietitian, says, “I think it’s irresponsible to take away this beverage that children enjoy, especially among those who are unable to meet their nutrient needs for the day, and remove it from the lunch line.”
The U.S. government is studying the request of the PCRM, but a decision may be a long way off. Meanwhile, Marion Nestle, a professor at New York University, puts it best: “Milk has nutrients. Other foods have the same nutrients. It’s just a food. Like other foods, too much might be a problem.”
小题1:What is mainly talked about in the first paragraph?
| A．The concern about students’ health. | B．Traditional attitudes towards milk. |
| C．Ways to keep bones and teeth healthy. | D．The practice of the U.S. government. |
| A．children like its taste | B．people ignore its disadvantages |
| C．it contains more calcium than other foods | D．the calcium in it can build up bone strength |
| A．bone strength is determined by many factors |
| B．people’s diets shouldn’t contain animal protein |
| C．the opinion of the PCRM will soon be accepted |
| D．people should turn to vegetables for calcium |
As a basic bodily and mental need, sleep is essential for our survival, it helps us to fight diseases, strengthen our memory, perform better in work and school and improve our quality of life. Lack of sleep is known to have a significant negative influence on health, both in the short and long term. Poor sleep has been associated with obesity, diabetes, weakened immune systems and even some cancers, as well as depression and anxiety.
The World Sleep Day, held on the third Friday of March, is an annual celebration of sleep to lighten the burden of sleep problems through better prevention and management of sleep disorders.
To achieve this goal, we must figure out what causes sleepiness and sleeplessness.
Unhealthy lifestyle may be the first to blame. More and more people use cell phones and computers in bed, with many staying up until midnight. Modern technology does make our life convenient, but abuse of it ruins our health. Environmental conditions, such as temperature, noise, light, bed comfort also play an important Pole in one"s ability to get proper sleep. Besides, improper evening diet, like a full or an empty stomach, coffee and alcohol all contribute to sleep problems. Of course, when it comes to causing poor sleep, stress from finances, family or work should never be ignored．
However, those who suffer from sleep disorders don"t necessarily have to continue to do so -most sleep problems can be managed．
小题1:What can be inferred from Paragraph 1?
| A．Nobody can stay awake for several days |
| B．Most people are going through sleep problems |
| C．Sleep problems have become a worldwide concern． |
| D．The majority of the world"s population can"t sleep well． |
| A．Unhealthy lifestyle． | B．Modern technology． |
| C．Environmental conditions． | D．Work stress． |
| A．The harm of sleep problems． |
| B．Activities on the World Sleep Day． |
| C．Interviews of poor sleep sufferers． |
| D．Measures against sleep problems． |
| A．Doubtful． | B．Disapproving． | C．Concerned． | D．Enthusiastic |
If you have a headache, toothache, backache, earache or bad pain in the stomach, if you complain of a bad cough, if you run a high temperature and have a bad cold, or if you suffer from high or low blood pressure, I think you should go to the doctor. The doctor will examine your throat, feel your pulse, test your blood pressure, take your temperature, sound your heart and lungs, test your eyes, check your teeth or have your chest X-rayed. After that, he will advise some treatment, or some medicine. The only thing you have to do is to follow his advice.
Speaking about doctor’s advice, I can’t help telling you a funny story. An old gentleman came to see the doctor. The man was very ill. He told the doctor about his weakness, memory loss and serious problems with his heart and lungs. The doctor examined him and said there was no medicine for his disease. He told his patient to go to a quiet place for a month and have a good rest. He also advised him to eat a lot of meat, drink two glasses of red wine every day and take long walks. In other words, the doctor advised him to follow the rule: “Eat with pleasure, drink with pleasure and enjoy life as it is.” The doctor also said that if the man wanted to be well again, he shouldn’t smoke more than one cigarette a day. A month later the gentleman came into the doctor’s office. He looked cheerful and happy. He thanked the doctor and said that he had never felt a healthier man.“ But you know, doctor,” he said, “it’s not easy to begin smoking at my age.”
小题1:The writer thinks that_____.
| A．health is more important than wealth |
| B．work is as important as studies |
| C．medicine is more important than pleasure |
| D．nothing is more important than money |
| A．without examining the patient | B．after he has examined the patient |
| C．if the patient doesn’t take medicine | D．unless the patient feels pain |
| A．he was feeling better than ever | B．he wasn’t a healthy man |
| C．he was feeling worse than before | D．he will be well again |
| A．was a heavy smoker | B．didn’t smoke so much |
| C．didn’t smoke | D．began to learn to smoke |
| A．The doctor usually tests his/her blood pressure when a person is ill. |
| B．The man told the doctor he couldn’t remember things. |
| C．The man thanked the doctor. |
| D．The man didn’t follow the doctor’s advice. |
“People are just likely to get sick from their phones as from handles of the bathroom, ” Jeffrey Cain, the president of the American Academy of Family Physicians , told The Wall Street Journal.
This may be hard to believe, but scientists reached this conclusion after they tested eight cell phones from an office in Chicago. All the tested phones showed high numbers of coliforms (大肠菌), a kind of bacteria found in human waste , with about 2700 to 4200 units of the bacteria on each phone. The bacteria can cause flu, pinkeye and other diseases . That is right --- your phone is covered in our human waste.
Although computers, keys and pens carry germs (细菌) , our phones get far dirtier. They touch a lot of things, including our hands and the inside of our pocket or purse. We take them almost everywhere: the bus, the subway and who hasn’t played Angry Birds or Fruit Ninja while sitting on the toilet?
“Some things that we think are personal are actually more public than we imagine,” Cain said. What is even worse is that after the phone returns from its dirty trip, it then spends most of its time cozying up to our faces. You don’t think about how often you touch your phone to your face, do you? Our noses, mouths and ears are all warm and rich in grease (油脂) , an environment that germs really like.
So how do you keep your phone clean? Alcohol is effective when used to kill germs from the back and side of your phone. But it might harm the screen. There is one simple and reliable way you can reduce the germs on your phone’s surface: wash your hands regularly.
