7、an Williams，who led the study and works at the Max Planck Institute for Chemistry in Mainz，Germany.Williams started out measuring the air in a soccer stadium.He wanted to see if the fans exhaled(呼出的) breaths might affect levels of greenhouse gases in the air.Carbon dioxide, which people breathe out，
8、is one example.And he found the answer was no at least on a small scale.But he noticed levels of carbon dioxide shifted wildly whenever the crowd cheered.That got him wondering：Could the gases people exhale be influenced by emotions?So Williams went to the movies.He and his coworkers measured air sa
9、mples collected over six weeks in two movie theaters.Overall,9,500 moviegoers watched 16 films including a mix of comedy，romance，action and horror films.Then they looked for hundreds of chemicals in the air that showed up as people were watching particular movie scenes.Scenes that had people laughin

15、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 hard

17、aid.“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 tra
18、ined 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 Walesdev
19、eloped 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

31、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，理解；get through通过，做完。由题意知是“执行计划”，故选B。阅读能力与写作能力专练.语篇解读 本文是一篇说明文。科学研究发现，看电影时你的呼吸能显示你当时的情感状态。1B细节理解题。由第三段的“.he noticed levels of car
32、bon dioxide shifted wildly whenever the crowd cheered.”可知，Jonathan Williams在足球场的发现是：人的欢呼声能改变空气中二氧化碳的含量。2A词义猜测题。划线部分与之前的laughing构成对比，同时根据下文的terrifying moments和tense movie moments可推知，划线部分应该是“紧张的”(nervous)意思。3D推理判断题。由最后一段的“But Williams can see possible practical uses.”可推知，Williams认为他的研究是有意义的。4C标题归纳题。第一
33、段为文章的主题段，由该段可知文章围绕“看电影时你的呼吸能说明你当时的情感”展开。故C项最符合。语篇解读 本文是一篇科技类说明文。为了研究麻疹和患感染性疾病死亡之间的关联性,迈克尔米纳和他的团队开展了一项基于历史数据的非传统的研究,此研究也引起科学界不同的看法。5A推理判断题。根据文章第六段“To test if a similar thing may occur in humans，the group mined historical data to find out the relationship.”可知。6C细节理解题。根据文章第三段中的“That reemphasizes the importance of vaccination(疫苗)， said biologist Michael Mina，.”和文章第四段第二句“I hope this study can impress upon people the danger measles poses.”可知。7A词义猜测题。根据本句提到的“.immuneamnesia(免疫缺失) that makes it harder for people to stave off other illnesses.”可知。8C标题归纳题。本文主要介绍了一个研究团队开展麻疹病毒对人体免疫系统长期影响的研究，故选C项。专心-专注-专业
