The Olympic Games*阅读理解Crossing your legs is an extremely mon habit; most people dont even notice that theyre doing it when they sit down. While you may find it fortable to sit with one knee crossed over the other, it might be causing health problems that you are not aware of.A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure. The reason for this is that the blood in your legs has to work against gravity to be pumped back to your heart and that crossing one leg over the other increases resistance, making it even harder for the blood to circulate. This causes your body to increase your blood pressure to push the blood back to the heart. You wont feel any immediate effects, but repeated, drawnout increases in blood pressure can cause longterm health issues. So, planning to sit for a long period of time? Dont keep your legs crossed.“Crossing your legs at the knee can also cause pressure on the major nerve in your leg that passes just below your knee and along the outside of your leg，” explains Richard Graves, a medical expert. This pressure can cause numbness and temporary paralysis(麻痹) of some of the muscles in your foot and leg, preventing you from being able to raise your anklewhat we know as that “pins and needles” sensation. While the feeling of disfort may only last a minute or two, repeatedly crossing your legs until they feel numb can cause permanent nerve damage.So next time you sit down, try to get yourself in the habit of sitting with both of your feet on the floor. Not only will it help your posture and stability, but it will also save your health in the long run.【解题导语】本文是一篇科普说明文。研究表明，虽然跷二郎腿是常见的习惯，但是该习惯会引起血压的升高，还会导致膝盖以下的重要神经受损。所以不要跷二郎腿，要有正确的坐姿。1What can we learn about crossing ones legs?AIt is a very bad social habit.BIt is usually practiced deliberately.CIt can do harm to peoples health.DIt can make others feel unfortable.C解析：细节理解题。根据第一段的第二句可知，跷二郎腿会引起健康问题，故C项正确。2According to the study, sitting with your legs crossed can Aaffect your blood pressureBresist gravity effectivelyClead to heart attacks easilyDimprove the function of legsA解析：细节理解题。根据第二段的第一句可知，研究表明，跷二郎腿会引起血压的升高，故A项正确。3In the third paragraph “pins and needles” probably means “ ”Aslightly sharp painsBbeing a little tiredCserious muscle injuriesDbeing highly flexibleA解析：词义猜测题。根据第三段的“This pressure can cause numbness and temporary paralysis(麻痹) of some of the muscles in your foot and leg, preventing you from being able to raise your ankle”可知，这种压力会导致腿部和脚的一些肌肉暂时麻痹，使人无法站立，有一种针刺感；据此可以判断，画线词意为“轻微的针刺感似的疼痛”，故A项正确。4What is the main purpose of the text?ATo pare mon habits.BTo give readers some advice.CTo evaluate the effects of an experiment.DTo introduce research methods.B解析：写作意图题。根据全文内容尤其是最后一段可知，本文通过分析跷二郎腿这一习惯导致的健康问题，建议人们不要跷二郎腿，要有正确的坐姿，故B项正确。*语法填空Do you make friends _1_(easy)?

“调查”，是可数名词，此处泛指“一项调查”，所以用不定冠词a。3filled考查动词的时态。句意：参与者首先填写了关于他们的社交生活的问卷，然后他们被要求尽可能长时间地身体贴墙，膝盖弯曲成直角，这可能很痛苦。分析句子结构可知，该空应填谓语动词，而且是描述过去的事情，所以用一般过去时，故填filled。4to press考查非谓语动词。ask sb. to do sth.为固定搭配，意为“要求某人做某事”，此处是其被动结构形式be asked to do sth.。故填to press。5knees考查名词的复数。knee “膝盖”，是可数名词，其前有their修饰，所以要用复数形式，故填knees。6which考查定语从句的引导词。设空处引导非限制性定语从句，引导词指代整个主句的内容，并且在从句中作主语，故填which。7their考查代词。该空代替的是participants，而且后面有名词network，所以要用复数形式的形容词性物主代词，故填their。8because考查表语从句的连接词。句意：这是因为大脑的镇痛系统与疼痛的耐受性和社会关系都有关，这意味着这个系统越活跃，你在这两个方面表现得越好。此处表原因，故填because。9with考查介词。be associated with为固定搭配，意为“与有联系”，故填with。10better考查形容词的比较级。“the比较级，the比较级”为常用句式，意为“越，越”，故填better。*完形填空。Something quite tragic(悲剧的)happened in our home.It had a _1_ effect on our lives.It _2_ the way we

v发生1D根据上下文可知，家里没有WiFi对我们生活的影响是巨大的(huge)。possible“可能的”；modest“谦虚的”；positive“积极的”。2B根据前一句“It had a _1_ effect on our lives”和下文的“But，what will we do”可知，平时家里离不开WiFi，现在没有了，当然对我们平时的生活方式产生挑战。explore“探索”；improve“提升”；guarantee“保证”。3C根据下文的“When given the news that there was no WiFi in the house”可知，我们家里失去(lost) WiFi一个多星期；receive“收到”；book“订购”；buy“购买”。4B根据第二段第一句“I was raised in the preWiFi era”可知，“我”是在没有WiFi的时代长大的，因此对于没有了WiFi也是比较习惯的(accustomed)，be accustomed to表示“习惯于”。5A根据上下文可推知，“我”习惯无WiFi的生活，但是孩子们不习惯。上下文是转折关系，因此选however。6C根据空后的“But, what will we do”可知空处指的是他们的第一反应(response)。7D根据上下文可知，没有WiFi只有电视，且电视频道只有70多个，孩子们很绝望。excited“兴奋的”；grateful“感激的”；embarrassed“尴尬的”；desperate“绝望的”。8B根据本句的定语从句“most of which is now given online”可知，家庭作业应是孩子们的主要(major)挑战。avoidable“可避免的”；enjoyable“令人愉快的”；simple“简单的”。9A空后的“the dog ate my homework”表示“狗吃了我的作业”，此处表示没有网络是这种借口的一个新提法，故选A。10C根据空后的宾语从句“that one of her friends had her water supply temporarily_11_ due to a leak”可知，这些内容应该是女儿讲出来(observed)的。 repeat“重复”；promise“承诺”；ignore“忽略”；observe“观察，说，评论”。11B根据该空后的“due to a leak”可推知，水管漏水了，供水会被暂时中断(cut off)。12A根据上下文可知，女儿认为我们没有WiFi更糟糕(worse)。13D根据上下文可知，为了能够在家工作，丈夫和“我”需要互联网。enable sb.to do sth.表示“使某人能做某事”。14C根据下文的“Although expensive”可知，“我”去商店买(purchase)WiFi。 look into“调查”；search for“寻找”；borrow“借”。15A根据语境可知，买了WiFi，“我”建立自己的网络就容易了。16D根据本句中的“like leaving a tap running(像让水管的水不停地流着一样)”可知，我们知道让水管的水不停地流着意味着“浪费”，故选D。17B根据上下文可知，当“我”上网做事时，“我”是尽快地做，as quickly as possible表示“尽快地”。18A根据语境可知，技术已经引起了我们日常生活的改变，这些改变在我们没有注意(noticing)的情况下发生了。19D参见上题解析。reflect“反思”；hear“听到”；appreciate“欣赏”。20C根据该空后的“without WiFi was seeing the children make forts(堡垒)out of the sofa cushions，which they havent done in years”可知，没有了WiFi，孩子们可以在一起玩，这是愉快的(bright)事情。*短文改错。Dear Lisa，Im glad to receive your letter asked about the present holiday life of Chinese students. Learning together with entertainment still take up most of our time. Besides, we often help our parents with the housework or farm work, that makes us realize how hard we work every day and develop a great love for work. Meanwhile, we take active part in social activities, such as voluntary work. We went out to the streets to collect rubbishes or to the hospitals to cheer up the sick children. We try our best to help those who are in need or make our hometown a lot of more beautiful. We find greatly pleasure in these activities.Yours，Li Ming答案：Dear Lisa，Im glad to receive your letter about the present holiday life of Chinese students. Learning together with entertainment still up most of our time. Besides, we often help our parents with the housework or farm work, makes us realize how hard work every day and develop a great love for work. Meanwhile, we take active part in social activities, such as voluntary work. We out to the streets to collect or to the hospitals to cheer up the sick children. We try our best to help those who are in need make our hometown a lot more beautiful. We find pleasure in these activities.Yours，Li Ming难项分析：第二处：taketakes此处together with后的名词不影响谓语动词的数，句子的主语是learning，谓语动词用第三人称单数形式，故改为takes。第七处：rubbishesrubbishrubbish表示“垃圾”，是不可数名词，没有复数形式，故改为rubbish。第九处：去掉of此处指使我们的家乡变得更加美丽。根据句中的“more”可知，此处修饰比较级，表示程度，故应用a lot。a lot of表示“许多”，修饰名词。
