Even now, although we know that tiny living microbes cause disease, how the

12、y do so is not always obvious._ They can also be transmitted through our skin through insect or animal bites. The best way to prevent infections is to block pathogens(病原体) from entering the body. The first line of defense is to keep germs at bay by following good personal health habits. Wash your ha

13、nds well. You probably wash your hands after using the bathroom, before preparing or eating food, and after gardening or other dirty tasks._ Wet your hands thoroughly. Lather(起泡沫) up with soap or cleanser, and rub it into the palms and backs of your hands and your wrists. Be sure to clean your finge

18、owing your nose, coughing, or sneezing.三、阅读理解 Weve known that sitting for long periods of time every day has countless health consequences, like a higher risk of heart disease. But now a new study has found that sitting is also bad for your brain, which runs counter to received ideas about deep thou

19、ght, from our teachers, who told us to sit down and focus, to Rodins famous Thinker, seated with chin on hand. A study published last week, conducted by Dr. Prabha Siddarth at the University of California, showed that sedentary(久坐的) behaviour is associated with reduced thickness of the medial tempor

20、al lobe (中颞叶), a brain area that is critical to learning and memory. The researchers asked a group of 35 healthy people, aged 45 to 70, about their activity levels and the average number of hours each day spent sitting and then scanned their brains. They found that the subjects who reported sitting

21、for longer periods had the thinnest medial temporal lobes. It means that the more time you spend in a chair the worse it is for your brain health, resulting in possible damage to learning and memory. What is also interesting is that this study did not find a significant association between the level

22、 of physical activity and thickness of this brain area, suggesting that exercise, even severe exercise, may not be enough to protect you from the harmful effects of sitting. It then surprisingly turned out that you dont even have to move much to enhance cognition(认知) ;just standing will do the trick

23、. For example, two groups of subjects were asked to complete a test while either sitting or standing. Participants are presented with conflicting stimuli(刺激), like the word green in blue ink, and asked to name the colour. Subjects thinking on their feet beat those who sat by a 3-millisecond margin.

24、The cognitive effects of severe physical exercise are well known. But the possibility that standing more and sitting less improves brain health could lower the bar for everyone.1. Which of the following can best replace the phrase runs counter to in paragraph 1?A. Goes against. B. Bears out. C. Push

25、es forward. D. Corresponds with. 2. Which of the following best explains do the trick underlined in paragraph 5?A. Set a trap. B. Do a deal. C. Get to the point. D. Get the desired result. 3.

32、ng the body.可知,防止感染的最好方法是阻止病原体进入人体。因为大多数微生物通过身体进入体内,导致人感染。故选F项。 考查上下文语境。前文的Wash your hands well. You probably wash your hands after using the bathroom, before preparing or eating food, and after gardening or other dirty tasks.介绍了人们在什么情况下会及时洗手。G项You should also wash up after blowing your nose, coughi

33、ng, or sneezing.提到了另外几种需要洗手的情况,与前文需要洗手的情境为并列关系。故选G项。 考查上下文语境。前文提到洗手的方法和步骤,洗手后需要擦手。A项Dry your hands and wrists thoroughly.表示彻底擦干手和手腕,符合语境。 考查主下文语境。结合后文.such as a temporarily sore arm or low fever, they are generally safe and effective.可知,接种疫苗后会有手臂酸痛或低烧等症状。C项While vaccines may cause some common side e

34、ffects,表示疫苗可能会引起一些常见的副作用,符合语境。考查段落主题句。结合后文Many wild animals, including bats, foxes and coyotes, can spread the virus to humans by biting.可知,许多野生动物,包括蝙蝠、狐狸和郊狼,可以通过咬人将病毒传播给人类。故可推知动物会传播疾病,防止感染需要管控动物。B项Use animal control to prevent infections.表示使用管控动物的方法来防止感染,符合语境。三、阅读理解答案：1-3 ADD 解析：1.词义猜测题。本题问及下列哪一项是替

35、代第一段划线短语“runs counter to”的最佳选项。划线短语前面But now a new study has found that sitting is also bad for your brain提至一项新的研究发现坐着对大脑有害,而后半句received ideas about deep thought, from our teachers, who told us to sit down and focus, to Rodins famous Thinker, seated with chin on hand则介绍了公认的关于深思的观念是坐着并集中注意力。由此可知, “坐着

36、对大脑有害”与公认的观念相反,由此可推测划线短语runs counter to意为“与相反,与背道而驰”。go against“与相背”;bear out “证实”;push forward “推进”;correspond with “与一致”。故选A。2.词义猜测题。本题问及下列哪一项能最好地解释第五段中的划线短语do the trick。根据划线处下文的For example可知,其后内容是对划线部分所在句的具体举例说明。 划线部分所在句句意为:结果令人惊奇的是,你甚至不需要为增强认知做太多动作,只要站着就可以_。而下文所举的例子则证实站着思考的受试者比坐着的受试者反应更快、思维更敏捷。也

37、就是说,“站着”这一行为成功达到了“增强认知”的目的。由此可推断出, do the trick 有“起作用,达到目的”之意。 此外,划线词前面的dont even have to和just也从语气上进行了暗示。set a trap“设陷讲”;do a deal“达成交易”;get to the point “谈到正题”;get the desired result“达到期望的目的”。D项与do the trick意思相近。故选D。3.词义猜测题。本题问及下列哪一项与第五段中的划线词margin意思最接近。根据划线词所在句Subjects thinking on their feet beat

38、those who sat by a 3-millisecond margin.可知,站着思考的受试者击败了坐着的受试者。根据语境可知, by a 3-millisecond margin是指获胜者快了 3毫秒,即以3毫秒的差额取胜,所以margin在此处为“差额”之意。blank“空白处,空格”;edge “边缘”;decrease “减少”;difference “差别;差额”。 D项与margin意思最接近。故选D。四.本文是说明文。文章主要介绍了基因工程在植物、动物乃至人类应用领域的发展历程。1.that/which考查定语从句的关系代词。设空处引导限制性定语从句,修饰先行词DNA,且

39、在从句中作主语,故填that或which。2.improved考查动词-ed形式作定语。设空处作定语修饰production,表示“改进了的”,故填improved。3.cloned考查动词时态。由前面的in 1996可知,设空处所表示的动作发生在过去,应用一般过去时,故填cloned。4.to produce考查不定式作状语。新西兰一家公司改进了奶牛基因的目的是生产更有营养且不会引起人类过敏的牛奶,故填to produce。5.probably考查副词。设空处作状语,表示“有可能”,故填probably。6.increasing考查动词-ing形式作定语。设空处作定语,修饰debate,意为

40、“越来越多的”,故填increasing。7.be done考查被动语态。modifications与do之间是被动关系,又由空前的can可知,应填be done。8.there考查there be句型。设空处所在句意为:这项技术引起了激烈的争论,因为会有因为编辑基因而产生的“超级人类”取代现代人类的可能。故填there。9.conclusion考查名词。设空处在此作主语,意为“结论”,又由后面的was可知,应填conclusion。10.for考查介词。be responsible for.意为“对负责任”。第三课时 Grammar-phrasal verbsLearning Objecti
