高考英语阅读理解名校试题精炼1.Holding a cell phone against your ear or storing it in your pocket may be dangerous to your health. This explains a warning that cell phone manufacturers include in the small print that is often ignored when a new phone is purchased. Apple, for example, doesn’t want iPhones to come closer to you than 1.5 centimeters; Research In Motion, BlackBerry’ s manufacturer, recommends 2.5 centimeters.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 shouldtext rather than call, she said, and pregnant women should keep phones away from the abdomen(腹部).1.

People should use cell phones in the correct way.C. If you are a child, you’d better text rather than make phone calls.D. When you use a cell phone, use a wired headset or the phone’s speaker.4.

Low-energy radiation could damage cells that could lead to cancer.【文章大意】使用手机会带来辐射的负影响, 因此需要正确使用手机。

2.Tiredness, coughing, a runny nose and a sore throat—among all sicknesses there is probably none more common than the flu, which we all get now and then.However, bird flu is a completely different story.Ten years ago, the H5N1 bird flu swept across 15 countries, including China, with sufferers reporting chest pain, difficulty breathing, fever and severe coughing. More than 600 people were infected, and about 60 percent died. Now another type of bird flu hit Shanghai and three neighboring provinces, and this time the virus is called H7N9. By the afternoon of April 11, the new virus had taken nine lives out of 35 infected, according to Xinhua News Agency.The “H” and “N” in the virus’ name refers to two kinds of proteins on the surface of the virus. Any change of the numbers of the two proteins indicates a new mutation(变异). Most of the mutations only affect birds, such as chickens and pigeons, and don’t normally spread to humans. But once they do, the results can be disastrous.“Any time an animal influenza virus crosses to humans, it is a cause for concern, ”Malik Peiris, virologi st(病毒学家)at the University of Hong Kong, told Nature magazine. Take the SARS epidemic(传染病)10 years ago as an example. The virus behind the disease is thought to have jumped to humans from animals. The virus was a complete “stranger” to human bodies, which hadn’t developed an immunity against it.But there is something more about the new H7N9 bird flu. Unlike the H5N1 bird flu, which causes severe sickness in birds, the H7N9 has been evolving under the radar(悄悄地)since it travels between birds without causing noticeable illness. That makes it difficult to keep track of the disease.The good news is that there’s so far no sign that the virus is spreading from person to person. But since there is no vaccine for the disease yet, the World Health Organization recommends that you wash your hands after meeting with sick people andbefore and after you eat or prepare food, and they also suggest avoiding contact with birds or their eggs.5. Which of the following statements is TRUE according to the text?A. The H5N1 bird flu turned out to have something to do with the SARS epidemic.B. More than 600 people across the world died from the H5N1 bird flu ten years ago.C. Most of the mutations of the proteins in the bird flu virus are harmful to both birds andhumans.D. The name, H7N9 bird flu, shows that there have been new mutations of the proteins inthe virus.6. With the example of the SARS epidemic in Paragraph 5, the author intends to.A. introduce where the SARS virus came fromB. inform us of the harmful effects of the SARS epidemic ten years agoC. show the horrible effects an animal influenza virus can have once it spreads to humansD. compare the differences between the SARS epidemic and the H7N9 bird flu7. What makes the H7N9 bird flu more frightening than the H5N1 bird flu according to the text?A. It can cause severe sickness in birds.B. It can spread from person to person.C. It affects a greater number of birds.D. It doesn’t sicken birds and thus can spread unnoticed.8. What are people advised to do to protect themselves against the H7N9 bird flu?a. To get vaccinated for the disease.b. To keep away from birds and their eggs.c. To stop eating chickens and ducks.d. To avoid meeting with sick people.e. To wash hands thoroughly and regularly.A. a, bB. c, dC. b, eD. a, e【文章大意】新一波禽流感疫情来袭, 你该如何应对?6. 【解析】选C。
