BTouched. CHappy. DPuzzled.3What does Jonathan Williams think of his study in movie theaters?ACreative. BUnsuccessful.CSystematic. DMeaningful.4What is the best title for the passage?AWatching Movies Is Good for Our EmotionsBThe Useful Role of Chemical Signals in the AirCOur Breaths Show Our Emotions at the MoviesDReasons for Levels of Carbon Dioxide in TheatersBScientists have known for decades that having measles(麻疹) suppresses kids immune systems for several weeks or months,leaving them illequipped to fight off pneumonia,bronchitis and other infections.Now a team of researchers has suggested that the measles virus may also leave a longerlasting sort of “immuneamnesia(免疫缺失)” that makes it harder for people to stave_off other illnesses for two years or more.“That reemphasizes the importance of vaccination(疫苗),” said biologist Michael Mina,lead author of a paper that was published in the journal Science.“There may be a longlasting impact that you cant undo if your child gets measles,” he said.“I hope this study can impress upon people the danger measles poses.”The researchers used what Mina called “an unconventional approach” to search for the longlasting immune system effects.Previous work in monkeys suggested that monkeys with the disease lost white blood cells their bodies had trained to fight off other illnesses,leaving them more likely to be infected.To test if a similar thing may occur in humans,the group mined historical data to find out the relationship between measles incidence(发病率) and deaths from other infectious diseases.They turned to data from England and Walesdeveloped nations where disease levels are generally low,allowing a lessconfused view of measles effects.Studying measles incidence and deaths from infectious disease both before and after the introduction of the measles vaccine in the UK in the 1960s,Mina and the team saw a sort of shadow effect,where deaths from a variety of nonmeasles infectious diseases closely tracked measles incidence.The more measles in a population,the more deaths from other illnesses in the 28month period that followed.“Really it didnt matter what age group,what decade or what country,” said Mina.“They all showed consistent results.what were suggesting happens over the long term is that your immune system works fine,but it has forgotten what it previously learned.”Some researchers who were not involved in the work questioned whether the reductions in deaths as measles cases declined may have had more to do with improving nutrition and smaller family size than with prolonged immune suppression.Others thought the papers opinion of yearslong suppression was seemingly reasonable but said they could not comment on the mathematical models the group used.To know for certain what was behind the effect the group saw,Mina agreed,scientists would need to look at immune cells and observe their behavior.He said he would like to push the work in a more traditional direction:back into the laboratory.5Why did Mina call their research method “an unconventional approach”?ATheir research was based on the historical data.BTheir research compared monkeys with humans.CThey only paid attention to developed nations.DThey discovered a sort of shadow effect.6According to Mina,what is the significance of their research?AThey warned people that measles can result in other infectious diseases.BThey carried out the research on measles in an unconventional approach.CThey showed how dangerous measles is and the importance of vaccination.DThey found out the disease levels are generally low in developed nations.7The underlined phrase “stave off” in Paragraph 2 is closest in meaning to “_”Akeep away Bsurvive fromCsearch for Dturn down8Which of the following may be the best title of the passage?AMeasles Has Been the Origin of Other Diseases and DeathsBNew Research Conducted into Measles Has Been Widely QuestionedCStudy Points to Yearslong Immune System Misfortunes from MeaslesDDamage Caused by Measles to the Immune System Could Last Several Weeks.佳作背诵(科普知识与现代技术)你的美国笔友Tom来信和你讨论个人信息保护问题,让你就如何保护个人信息给他一些建议。请你以李华的名义重点从以下两个方面谈谈自己的看法:1给予足够重视;2学会如何保护。注意:词数150左右。文章的开头和结尾已给出,但不计入总词数。参考范文Dear_Tom,We_are_living_in_the_Information_Age.The protection of personal information is becoming more and more important.Here Id like to give you some advice on this.First of all,you should pay enough attention to the protection of your personal information.Remember: once youve shared something,you will lose control of it and some people may share upsetting things about you without you knowing it.Secondly,you must know how to protect your personal information.For example,never provide your personal information for any strangers or people you know online.If necessary,youd better confirm it is for legal use before letting it out.If you receive an officiallooking email that asks you to send your financial details,you should never reply as you could become a victim of identity fraud.Yours,Li_Hua答案精析第27练科技类(一)高考高频单词与短语识记排查跟踪训练.1.success2.brilliantly3.demanding4.experiments5accessible.6.B过去分词短语作状语,相当于When the fruits were first introduced to the mainland market。7Ccarry out the experiment完成(进行)试验;表语部分可用a success或successful。8D考查非谓语动词作状语。句意为:很明显,因为新政策,跟数年前相比,食物浪费自去年开始有大幅的降低。句中将去年以来的食物浪费与前几年相比,主语为food waste,与compare构成被动关系,故选D。9Cgovernment与support之间是被动关系,所以用过去分词。10Bset aside留出,驳回;carry out执行,贯彻;take in接受,
