To scare off the beast, people burnt bamboo joints to make them explodeG. The other way is that one child must try to find those who have hidden awayStephen Hawking died at the age of 76 on March 14, 2018. Hawking is known as the most famous physicist(物理学家) after Einstein. Hawking was born in Oxford, England, on January 8, 1942. During his life, he married twice, and had three children. When he was a kid, Hawking went to school in St. Albans—a small city near London. Although he did well, he was never top of his class. After leaving high school, Hawking went first to Oxford University to study physics, and then he went to Cambridge University to study the universe(宇宙). At the age of twenty, Hawking started noticing that something was wrong with him. Later, he went to the hospital and doctors said that he would die before he was 23. But Hawking didn't give up. In 1988, Hawking completed his book A Brief History of Time. In the book, he talked about many things, like the universe, the big bang(宇宙大爆炸) and the black hole.(1)At which university did Hawking study physics?A.Oxford University. B.St Albans University. C.ambridge University. D.London University.(2)Hawking first felt there was something wrong with his body when he was ___.A.21 B.22 C.12 D.20(3)Which of the following is NOT true?A.Hawking was a very famous physicist.B.Hawking married but didn’t have children.C.Hawking was born in Oxford, England in 1942.D.octors said Hawking would die before he was 23.(4)The passage is mainly about ________.A.Hawking’s lifeB.Hawking’s studyC.why Hawking got illD.how Hawking became famousMobile phones help us easily find people anywhere at any time. A mobile phone can include many things, such as games, music and Internet access (互联网接入). Today, 4.6 billion people around the world have mobile phones, according to CBS News. However, mobile phones may cause cancer, according to the World Health Organization. In a 2010 study, people who used a mobile phone for 10 years or more were more than twice as likely to get brain cancer, according to CNN. "I think it is a good idea to give the public some kind of warning that long﹣term exposure (暴露) to radiation (辐射) from your mobile phone could possibly cause cancer, " told Dr. Henry Lai. Lai is a scientist of bioengineering (生物工程) at the University of Washington who has studied radiation for more than 30 years. These suggestions may help you reduce your risk of cancer: 1.Use a headset (耳机) or speaker. Headsets give out much less radiation than phones. Some headsets give out low﹣level radiation. However, you should take the headset off your ear when you're not talking to anyone. Using your phone with a speaker will also make it safer. 2.Listen more, talk less. Your iphone gives out radiation when you talk or text, but not when you're listening or getting messages. Listening more and talking less can lower the risk of cancer. 3.Hold the phone away from your body. Hold the phone away from your body when you're talking, not against your ear.Also, don't keep it in your pocket. 4.Choose texting over talking. Phones, give out less radiation to send texts than to carry a person's voice. Texting also keeps radiation away from your head. 5.Poor signal? Stay off the phone. A poor signal means that the phone needs to give out more radiation to work. Make and take calls when your phone has a strong signal.(1)The study from 2010 showed that________.A.people should use mobile phones for no more than 10 yearsB.people who don't use mobile phones will not get brain cancerC.the longer people use mobile phones, the more likely they are to get brain cancerD.the more mobile phones people have, the more likely they are to get brain cancer.(2)Which is NOT true about the suggestions mentioned in the passage?________A.Some headsets don't give out radiation.B.It's not good to carry mobile phones in pockets.C.Texting is better than making phone calls.D.on't make calls when the signal is weak..(3)The passage mainly talks about________.A.the development and advantages of mobile phonesB.the reason why mobile phone radiation causes cancerC.the best ways to use mobile phones to communicateD.how to protect ourselves from mobile phone radiation.There are lots of dangerous and terrible insects in Northeastern India, but the tree﹣bees are the most terrible. They are killers. Unlike most bees which will sting (叮咬) you only if they are disturbed (打扰), tree﹣bees will attack you in thousands for no reason. And they will chase (追赶) you for your life. Walking along a dusty road while I was on holiday there last year. I found myself, without the least warning, the centre of such an attack. The air above me suddenly became thick with bees. Though it was hot, I went cold all over. Until then I had never heard of Indian tree﹣bees, but I had recently seen a film called "The Angry Swarm", which was about killer﹣bees. I began running to the village about half a mile away, but I was soon covered from head to foot with bees. I drove them away with my hands, only to make room for others. Each time I opened my mouth for breath, more bees entered my mouth, until it was stung to twice its usual size and I could hardly breathe. When I reached the village, I found some workers building a house. I ran towards them for help. But as soon as the workers saw the bees with me, they ran for safety at top speed. Soon my eyes had completely closed. I fell into a pile of brick dust. I pushed myself wildly down into it until my head and shoulders were covered. And then I tried hard to get out of the dust, the angry bees made a new attack on me. I was tired out and ran weakly about in circles. Soon I lost my consciousness (意识). Later I learned that two quick﹣minded villagers ran to a pile of dry grass and quickly surrounded (包围) me with a thick wall of fire and smoke until the bees were driven away. They stayed with me, taking stings out of my body for the next three hours until a doctor came and gave me further treatment.(1)What can we infer (推断) from the second paragraph?________A. The temperature went down at that time.B. The air suddenly became thick because of the dust.C. The writer knew Indian tree﹣bees were the most dangerous.D. The writer felt scared when he was surrounded by tree﹣bees..(2)In which order did the following things happen to the writer?________a. He tried to drive away the bees but failed. b. He was surrounded with a thick wall of fire and smoke. c. He was tired out and lost consciousness later. d. He watched a film named "The Angry Swarm". e. He was attacked by tree﹣bees while taking a walk.A. e﹣a﹣c﹣b﹣d B. d﹣e﹣a﹣c﹣b C. e﹣b﹣a﹣d﹣c D. d﹣e﹣a﹣b﹣c.(3)Which of the following is NOT true according to the passage?________A. Tree﹣bees often attack people in large numbers.B. Tree﹣bees can be driven away by fire and smoke.C. Tree﹣bees do not give up easily when they attack people.D. Tree﹣bees will not attack people unless they are disturbed..

阅读理解 The Chinese Antarctica expedition returned to Shanghai last Friday following a month living on the ice．It was the First time Chinese scientists had visited the Amery Ice Shelf?the longest ice shelf in the world．The team collected ice samples and data on temperatures, which are necessary for research on global warming．So far, about 27 countries have visited Antarctica for scientific research．Although the living conditions are very hard, many scientists have to stay there for long periods of time．So, how do they manage their lives on the ice? During the summer, the temperature in Antarctica reaches about －20℃．It falls to about －60℃ in winter．So, even if there are 24 hours of sunshine, scientists must keep wearing all the correct clothes to protect them from the cold．These clothes include jeans, running shoes, jackets, long underwear, boots and woolen socks．Although highly technical clothing provides much protection against the extreme cold, scientists often need to go outside when there is an icy wind blowing and the temperature is －30℃．Natural protection such as facial hair can also help．"That's why many researchers wear a beard．It really does keep you warm, " says German explorer Arved Fuchs． Usually, the polar researchers have good meals．Some even have feasts on holidays like Christmas and New Year's Day．Vegetables are always welcomed and usually finished the quickest．Life on the ice means living with other researchers in tight living spaces．Most people sleep in dormitory．More remote field camps use separate tents．So．at least some researchers don't have to put up with annoying snorers ． (1) Why did researchers visit Amery Ice Shelf? [ ] A． Because Amery Ice Shelf is the largest and most typical ice shelf． B． Because they wanted to challenge themselves in extreme climate． C． Because they desired to collect ice samples and data to study global warming． D． Because they were curious of the living conditions there． (2) What is the matter that researchers care most for living in Antarctica? [ ] A． Taking advantage of rare sunshine B． Putting up with annoying bears C． Having access to rich food D． Protecting themselves from coldness (3) What most describes the living space of most researchers on the Amery Ice Shelf? [ ] A． Small B． Changing C． Remote D． Unbearable (4) What does the underlined word of "snorers" mean? [ ] A． Those who wear a beard B． Those who like to do research on their own C． Those who have vegetables as their main food D． Those who breathe roughly and noisily while sleeping

【阅读理解】阅读文章选出正确的答案。　　It used to be so straightforward. A team of researchers working together in the laboratory would submit the results of their research to a journal. A journal editor would then remove the author’s names and affiliations from the paper and send it to their peers for review. Depending on the comments received, the editor would accept the paper for publication or decline it. Copyright rested with the journal publisher, and researchers seeking knowledge of the results would have to subscribe to the journal.　　No longer, The Internet---and pressure from funding agencies, who are questioning why commercial publishers are making money from government--funded research by restricting access to it---is making access to scientific results a reality. The Organization for Economic Co-operation and Development (OECD) was just issued a report describing the far-reaching consequences of this. The report, by john Houghton of Victoria University in Australia and Graham Vickery of the OECD, makes heavy reading for publishers who have, so far, made handsome profits. But it goes further than that. It signals a change in what has, until now, been a key element of scientific endeavor.　　The value of knowledge and the return on the public investment in research depends, in part, upon wide distribution and ready access. It is big business. In America, the core scientific publishing market if estimated at between 7 billion and II billion. The International Association of Scientific, Technical and Medical publishers says that there are more than 2,000 publishers worldwide specializing in these subjects. They publish more than 1.2 million articles each year in some 16,000 journals.　　This is now changing. According to the OECD report, some 75% of scholarly journals are now online. Entirely new business models are emerging; three ones were identified by the report's author. There is the so-called big deal, where institutional subscribers pay for access to a collection of online journal titles through site licensing agreements. There is open-access publishing, typically supported by asking the author (or his employer)for the paper to be published. Finally, there are open-access archives, where originations such as universities of international laboratories support institutional repositories. Other models exist that are hybrids of these three, such as delayed open-access, where journals allow only subscribers to read a paper for the first six months, before making it freely available to everyone who wishes to see it. All this could change the traditional form of the peer-review process, at least for the publication of papers.一、 In the first paragraph, the author discusses____. A、the background information of journal editing. B、the publication routine of laboratory reports. C、the relations of authors with journal publishers. D、the traditional process of journal publication. 二、 Which of the following is true of the OECD report? A、It criticizes government-funded research. B、It introduces an effective means of publication. C、It upsets profit-making journal publishers. D、It benefits scientific research considerably. 三、 According to the text, online publication is significant in that____. A、it provides an easier access to scientific results. B、it brings huge profits to scientific researchers. C、it emphasizes the crucial role of scientific knowledge. D、it facilitates public investment in scientific research. 四、 With the open-access publishing model, the author of a paper if required to____. A、cover the cost of its publication. B、subscribe to the journal publishing it. C、allow other online journals to use it freely. D、complete the peer-review before submission. 五、 Which of the following best summarizes the main idea of the passage? A、The Internet is posing a threat to publishers. B、A new modal of publication is emerging. C、Authors welcome the new channel for publication D、Publication is rendered easier by online service

Peer Pressure The phrase， "everybody's doing it，" is very much at the center of the concept of peer pressure. （1） ____ ，and so it is hardly surprising that some of their self-worth comes from the approval of others.This instinct （天性） is a powerful force in many people's lives. Peer Influence A student whose friends excel in academics may be forced to study harder and get good grades.Study groups，class projects，and even book clubs are examples of positive peer groups that encourage people to better themselves.While for certain individuals，seeking social acceptance is so important that it becomes like an addiction.（2） ____ .Groups of children may join in bullying newcomers in school. （3） ____ Schools and other organizations try to teach kids about the dangers of negative peer pressure.They teach kids to stand up and be themselves，and encourage them to decline to do things that they believe are wrong.Likewise，it can be helpful to encourage children to embrace the beneficial influence of positive peer groups. Active Parenting （4） ____ .Parents can take a number of steps，including working to build closer relationships with their children，getting to know both the children's friends and the parents of those friends，knowing who they're with，and providing structure and discipline at home. Self-Awareness Being self-aware is at the root of managing this type of pressure.（5） ____ . "Going with the flow，" so to speak，is not always a bad thing，but as each individual is still responsible for the consequences，it is important to be a thinking participant in the decision.A.Valuing Being OneselfB.attling Negative PressureC.People are social creatures by natureD.Parental involvement can help ease harmful peer pressureE.They may go so far as to abandon their sense of right and wrongF.People should consider why they feel drawn to taking a particular actionG.You should work out whether your real motivation is affecting others' decisions
