SHANGHAI—Health experts in Shanghai are calling for more protection for young children as the latest research shows about half of the youngsters are suffering from second hand smoke.
About 45 percent of children suffer passive smoking in families, 50 percent in public places, and almost 6 percent on public transportation, shows a research released by the Shanghai Children’s Medical Center on Tuesday.
“Not only adults but also children and newborn babies are at risk for the adverse effects of passive smoking，” said Tang Jingyan, a doctor at the Shanghai Children’s Medical Center.
“Actually, those young children whose bodies are still growing and developing are more sensitive to the effects of second-hand smoke.”
Research has shown that children who are expose d to second-hand smoke will suffer from more colds, coughs and sore throats, and they are more likely to suffer from bronchitis, pneumonia and will have a higher risk of developing cancer.
Doctors even suggested that children suffering passive smoking are more likely to have behavioral problems and may not develop mentally as quickly as their peers.
Other research by the Shanghai Children’s Medical Center has found that more than 80 percent of child patients in the center live in a smoke-filled household, where one or both parents smoke.
“Though doctors have stressed the harm of passive smoking over and over, it is still hard to reach a totally smoke-free home，” said a pediatrician named Zhang Yiwen, noting that parents are often tempted to smoke even though they have learned the harmful effects of second-hand smoke.
China has 540 million people suffering from passive smoke, 180 million of them younger than 15.The age of smokers is also getting lower, earlier reports said.
“There are more young smokers than b efore.You can see young people wearing a school uniform and carrying a schoolbag light a cigarette on the street.Some of them are even female students，” said Jing Xingming, a professor of children’s developmental behavior at the center.
“Children like to imitate adults, especially their parents.If parents often smoke at home, it is very likely children will develop a smoking habit, which can
cause a vicious circle，” Jin said.
Reports from the Ministry of Health said China has about 350 million smokers, of whom 15 million are underage smokers.Also, around 40 million of the country’s 130 million children aged between 13 and 18 had tried smoking, and 15 million had become addicted to tobacco.

The new sensor system seeks to avoid this problem by developing trees into a self-sustaining power supply.Each sensor is equipped with a battery that can be slowly recharged using electricity produced by the tree.“A single tree doesn’t generate a lot of power, but over time the ‘trickle (细流) charge’ adds up, just like ________”， said Shuguang Zhang, one of the researchers on the project and the associate dire ctor of the MIT’s Center for Biomedical Engineering (CBE)．The system produces enough electricity to allow the temperature and humidity sensors to wirelessly send out signals four times a day, or immediately if there’s a fire.Each signal spreads from one sensor to another, until it reaches an existing weather station that sends the data by satellite to a forestry command center in Boise, Idaho.

The crisis at Japan’s Fukushima Dai-Ichi nuclear energy center has raised questions about the future of the nuclear energy industry.Arjun Makhijani is president of the Institute for Energy and Environmental Research in the United States.He says the disaster in Japan is historic.
This week, the chairman of America’s nuclear agency said there is little chance that harmful radiation from Japan could reach the United States.Nuclear Regulatory Commission Chairman Gregory Jaczko also said America has a strong program in place to deal with earthquake threats.No new nuclear power centers have been built in the United States since 1979.That was when America’s worst nuclear accide nt happened at the Three Mile Island center in Pennsylvania.The accident began to turn public opinion against nuclear energy.
To support more clean energy production, the Obama government has been seeking billions of dollars in government loan guarantees to build new centers.Presently, about twenty percent of electricity in the United States comes from nuclear energy.But critics say nuclear power is too costly and dangerous to be worth further expansion.
German Chancellor Angela Merkel said Germany would close all seven nuclear power centers for a moment while energy policy is reconsidered.The European Union is planning to test all centers in its twenty-seven member nations.
Developing nations are less willing to slow nuclear expansion.China said it would co ntinue with plans to build about twenty-five new nuclear plants.And India, under a cooperation agreement with the United States, plans to spend billions on new centers in the coming years.
Japan has made nuclear energy a national priority since the 1970s.Unlike many major economies, Japan imports eighty percent of its energy.The Nuclear Energy Institute says twenty-nine percent of Japan’s electricity came from nuclear sources in 2009.The government planned to increase that to forty percent by 2017.
Nuclear plants supply fourteen percent of global electricity.Nuclear energy is a clean resource, producing no carbon gases.But radioactive waste is a serious unresolved(未解决的) issue.So_is_the_presence_of_nuclear_power_centers_in_earthquake_areas_like_the_ one_near_Bushehr,_Iran.
( )1.Which of the following countries is the least likely to expand its use of nuclear energy?

3．对症下药，各个击破。了解全文的大概意思之后，再把短文的问题简单看一遍，弄懂题意，然后带着问题再去寻读全文。这次阅读过程中要善于抓文章中的关键词句。寻读也就是迅速的查找需要了解的信息，是为某些特定的问题而阅读，因此阅读时要有较强的针对性，对与问题有关的数据，词句等仔细阅读，认真理解，同时结合不同考查内容的题型，采取如下解题对策： （1）事实询问题：这类试题通常是以疑问词what，who，when，where，why，how 等引起的特殊问句，就文章中某一词语、某一句子、某一段落或某一具体细节和事实进行提问。解答此类试题首先要弄清题目和每一个选项的含义，然后按题目要求寻找与之相关的细节，正确估计答案来源，同时注意题目和文章中的暗示作用。特别注意辨别各种信息，确认各种信息。 （2）推理判断题：此题要求我们通过表面文字信息去推测文章隐含的意思，对文章的发展情节及作者的态度、意图等做出合乎逻辑的的推理判断。这种题要求我们在阅读时要抓住文章的主题和细节、从分析文章的结构入手，根据上下文的内在联系，充分挖掘文章的深层含义。对暗含在文章中事件的因果关系，人物的动机，以及作者未言明的倾向、态度、意图、观点进行合乎逻辑的推理、分析和判断。同时善于抓住文中实质性的东西，不要被带假象的表面信息或似是而非的东西所迷惑。并且注意推断作者态度时要力求从作者的态度、观点去思考，切勿想当然，凭个人的观点习惯看法来回答的问题。 （3）数据推算题：此题要求我们就文章提供的数据，以及数据与文章中其他信息的关系做出计算和推断，然后做出选择。这就要求我们解题时，要在理解好题意的前提下去对与数据有关的信息认真分析，若数据信息较多，还要注意弄清数据之间的关系，同时分清有用与无用信息，最终作出正确判断。 （4）主旨大意题：此题用以考查我们对文章主题或中心思想的领会和理解能力。在解答此类试题时要注意每段的中心句，抓住每一段的主题句。一般主题句都用来表达一段主旨大意，因此，只要找准每段的主题句，文章的中心思想和文章的最佳标题也就不难确定了。
2012年广东省高考英语听说考试真题 A Part A Reading Aloud Natural medicines, made from flowers, seeds, roots and leaves. The Chinese were the first to discover the power of plants, making medicine for 4000 years.

（英语）高三英语阅读理解专项训练及答案 一、高中英语阅读理解 1．阅读理解 The setting was a packed gymnasium just before the start of a game against another school. There were five girls who were members of the Danville High School basketball team—all of them starters. They were not in uniform to play that night and would not be on the team for the rest of this season. They were there to admit their breaking of team rules. They were there to support their coach's decision to take them off the team. They were there to let the town know there was a problem in their little community that needed to be addressed. And they did it with sincere regret rather than defensiveness. While the school had been out for the New Year's holiday, the five girls had gone to the party with several of their friends. There was alcohol there. And they all drank some. Coach Rainville has a zero tolerance rule on drugs and alcohol for her members though it was a hard decision to make. When classes resumed and accounts of holiday parties were shared, rumors about the five girls began closing in on them. The coach said she couldn't back down on her rules. And the players—two junior students and three senior students—agreed. That night in the gym was part of their public support of the coach's decision. “We hope you will understand that we are not bad kids. What we did was definitely not worth it. We hope this event will make everyone realize that there is a big drug and alcohol problem in our community,” one of the senior students said, “And if you work with us to try to solve this problem, you will help us feel that we have not been thrown off our basketball team for nothing.” The five left the floor to deafening applause. The team may not win another game this year. But they've learnt something about personal responsibility, the effect of one's action on others, and honesty that will serve them well throughout life. （1）It can be inferred from the passage that the five girls who were kicked off the team were ________. A. very good players on the team B. addicted to alcohol and drugs C. three junior students and two senior students D. scolded by their parents for drinking alcohol （2）What did the girls do to support their coach's decision? A. They didn't fight for Danville High School any more. B. They all gave speeches to apologize in the local press. C. They admitted their mistake in public in the gymnasium. D. They would never drink any alcohol throughout their life. （3）Which word best describes the coach Rainville? A. Indifferent. B. Strict. C. Stubborn. D. Cruel. （4）Which would be the best title for the passage? A. Growing up with pain B. A bad mistake C. Team rules are everything D. Basketball girls in high school 【答案】（1）A
2012届高考英语二轮专题总复习阅读理解精选（三） A AMSTERDAM (AP)－She’s not afraid of pirates(海盗). She’s packed plenty of school books. And she’s going to miss her family and her dog, Spot. Fourteen-year-old Laura Dekker jumped onto her boat Wednesday and sailed off from the Netherlands hoping to become the youngest person to make a voyage around the world by herself. About 100 supporters waved as Laura and her father Dick Dekker left the southern Dutch harbor of Den Osse in her 11.5-meter-long sailing boat Guppy, for Portugal wh ere she plans to leave her father and begin her attempt to travel around the world. Last week, Laura won a legal battle when a court released her from the guardianship(监护) of Dutch child protection agencies. They had blocked her initial plan to depart at age 13 over fears for her safety and psychological health during the trip, which will likely take around a year. “I can be sailing now, and that’s great！”she told reporters Wednesday. Laura raised the black Jolly Roger－like flag of the Sea Shepherd Conservation Society above the two red masts(桅杆) before sailing out. Laura, who was born on a sailing boat off the coast of New Zealand, has been working to counter objections to her voyage since the authorities stepped in last year. She got a bigger, stronger boat, took courses in first aid and practiced coping with sleep deprivation(缺乏)．She also made at least one trip by herself across the North Sea to England. The Dutch court ruled that Laura’s preparations were adequate and it was up to her parents, who are divorced, to decide whether to let her make the attempt. Her mother, Babs Mueller, recently withdrew(撤销) her opposition to the plan. Dekker’s case has fueled a global debate over the wisdom of allowing ever-younger sailors to take on the great risks of sailing the high seas alone. 荷兰14岁少女Laura Dekker将独自驾驶帆船环球航行，挑战全球最年轻独自环球航行纪录。1．How did Laura feel when she was setting off? A．Embarrassed. B．Surprised. C．Excited. D．Anxious. 解析推理判断题。根据第五段的“I can be sailing now，and that’s great！”一句可知，Laura出发时非常激动和开心。 答案 C 2．Which statement is true about Laura’s mother? A．She thinks highly of Laura’s adventure. B．She no longer shows concern about Laura. C．She decides to disapprove of Laura’s voyage. D．She opposed Laura’s attempt at the beginning. 解析推理判断题。根据文章的倒数第二段可知，Laura的母亲最近撤销了对女儿独自航行计划的反对，可见最初母亲反对女儿孤身去环球航行。 答案 D 3．What is the text mainly about?

2. The underlined sentence in the passage means that you’d better ask for a raise ______. A. when the employer has a normal pulse rate B. when the employer is in a good mood C. when the company has a good financial situation D. when the company’s practices are more flexible 3. Which of the following is NOT true? A. The employer will give you a raise because of your personal reasons. B. You should show them that you’re worthy of a salary increase. C. You can tell your boss the exact number of salary increase you want D. Schedule a meeting with your boss but don’t push too hard. 4. It can be inferred in the last paragraph that ______. A. If your boss won’t give you a raise, you’d better take fewer responsibilities. B. It is a wise way to get a raise by letting your boss know you are doing more. C. Only if you find a proper time to talk with your boss will you get a raise. D. You should schedule a meeting within a few months to discuss the matter again. B Here’s one number to keep in mind during your next cell phone conversation: 50. A new experiment shows that spending 50 minutes with an active phone pressed up to the ear increases activity in the brain. This brain activity probably doesn't make you smarter. When cell phones are on, they emit (发出) energy in the form of radiation that could be harmful, especially after years of cell phone usage. Scientists don't know yet whether cell phones are bad for the brain. Studies like this one are attempting to find it out. The 47 participants in the experiment may have looked a little strange. Each one had two Samsung cell phones attached to his or her head — one on each ear. The phone on the left ear was off. The phone on the right ear played a message for 50 minutes, but the participants couldn't hear it because the sound was off. With this set-up, the scientists could be sure they were studying brain activity from the phone itself, and not brain activity due to listening and talking during a conversation. After 50 minutes with two phones strapped to their heads, the participants were given PET scans. The PET scan showed that the left side (the side with the phone turned off) of each participant's brain hadn't changed during the experiment. The right side of the brain, however, had used more glucose, which is a type of sugar that provides fuel to brain cells. These right-side brain cells were using almost as much glucose as the brain uses when a person is talking. This suggests th at the brain cells there were active ― even without the person hearing anything. That activity, the scientists say, was probably caused by radiation from the phone. Henry Lai, who works at the University of Washington in Seattle, is uncomfortable with the data related to cell phones. Holding a cell phone to your ear during a conversation is “not really safe,” Lai told Science News. Lai is a bioengineer at the University of Washington in Seattle. He wrote an article about the new study for a journal, but he did not work on the study. Bioengineers bring together ideas from engineering and biology. For those who don't want to wait to find out for sure whether cell phones are bad for the brain, there are ways to talk more safely. You can have short and sweet conversations, use a
高考英语阅读理解专项训练及答案及解析 一、高中英语阅读理解 1．阅读理解 Traditional Chinese medicine (TCM) is gaining global popularity. According to a government white paper, TCM has been introduced in 183 countries and regions around the world. Westerners' understanding of TCM, however, may be limited to acupuncture, cupping and massage(针灸，拔罐和按摩). For instance, the purple, injury-like marks left on U. S. swimmer Michael Phelps，back from cupping for the purpose of relaxing his muscles and reducing pain became the center of attention during the Rio Olympics in 2016. As a matter of fact, Chinese herbs play a more important role in getting rid of diseases and keeping the body in good condition in the TCM treatment system than physical treatment. It is therefore disheartening to know that while 103 World Health Organization member countries have given approval to the practice of acupuncture, not many recognize Chinese herbal medicine. TCM falls far behind Western medicine owing partly to the slow development of Chinese herbs. Herbs are made into pills, powder and soup, and the kind of herbs used, their quality and quantity, and the processing of the ingredients (原材料) jointly determine the effectiveness of the prescription. Compared with Western medicine, which has standardized drug production processes and treatment methods, TCM lacks standardization, with the chemical composition and functions of its medicines being unclear and their effects being unstable. Fortunately, standardization has improved in recent decades, with an increasing number of factories producing patented TCM drugs. Another factor that has prevented the development of TCM prescription drugs is the lack of creativity. While Western medicine-making companies come up with new products every year, TCM drug producers tend to make medicines according to prescriptions handed down from the past. Chinese chemist Tu Youyou's winning the 2015 Nobel Prize in Physiology or Medicine for her research into malaria (疟疾) treatment may drive creativity to some extent in China's TCM industry.
