The Olympic Games*閱讀理解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.【解題導(dǎo)語】本文是一篇科普說明文。研究表明，雖然蹺二郎腿是常見的習(xí)慣，但是該習(xí)慣會(huì)引起血壓的升高，還會(huì)導(dǎo)致膝蓋以下的重要神經(jīng)受損。所以不要蹺二郎腿，要有正確的坐姿。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：細(xì)節(jié)理解題。根據(jù)第一段的第二句可知，蹺二郎腿會(huì)引起健康問題，故C項(xiàng)正確。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：細(xì)節(jié)理解題。根據(jù)第二段的第一句可知，研究表明，蹺二郎腿會(huì)引起血壓的升高，故A項(xiàng)正確。3In the third paragraph “pins and needles” probably means “ ”Aslightly sharp painsBbeing a little tiredCserious muscle injuriesDbeing highly flexibleA解析：詞義猜測題。根據(jù)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，這種壓力會(huì)導(dǎo)致腿部和腳的一些肌肉暫時(shí)麻痹，使人無法站立，有一種針刺感；據(jù)此可以判斷，畫線詞意為“輕微的針刺感似的疼痛”，故A項(xiàng)正確。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：寫作意圖題。根據(jù)全文內(nèi)容尤其是最后一段可知，本文通過分析蹺二郎腿這一習(xí)慣導(dǎo)致的健康問題，建議人們不要蹺二郎腿，要有正確的坐姿，故B項(xiàng)正確。*語法填空Do you make friends _1_(easy)?

friends，所以要用副詞，故填easily。2a考查冠詞。句意：牛津大學(xué)的研究者們做了一項(xiàng)調(diào)查，該調(diào)查由18歲到34歲之間的101個(gè)人參加。study “調(diào)查”，是可數(shù)名詞，此處泛指“一項(xiàng)調(diào)查”，所以用不定冠詞a。3filled考查動(dòng)詞的時(shí)態(tài)。句意：參與者首先填寫了關(guān)于他們的社交生活的問卷，然后他們被要求盡可能長時(shí)間地身體貼墻，膝蓋彎曲成直角，這可能很痛苦。分析句子結(jié)構(gòu)可知，該空應(yīng)填謂語動(dòng)詞，而且是描述過去的事情，所以用一般過去時(shí)，故填filled。4to press考查非謂語動(dòng)詞。ask sb. to do sth.為固定搭配，意為“要求某人做某事”，此處是其被動(dòng)結(jié)構(gòu)形式be asked to do sth.。故填to press。5knees考查名詞的復(fù)數(shù)。knee “膝蓋”，是可數(shù)名詞，其前有their修飾，所以要用復(fù)數(shù)形式，故填knees。6which考查定語從句的引導(dǎo)詞。設(shè)空處引導(dǎo)非限制性定語從句，引導(dǎo)詞指代整個(gè)主句的內(nèi)容，并且在從句中作主語，故填which。7their考查代詞。該空代替的是participants，而且后面有名詞network，所以要用復(fù)數(shù)形式的形容詞性物主代詞，故填their。8because考查表語從句的連接詞。句意：這是因?yàn)榇竽X的鎮(zhèn)痛系統(tǒng)與疼痛的耐受性和社會(huì)關(guān)系都有關(guān)，這意味著這個(gè)系統(tǒng)越活躍，你在這兩個(gè)方面表現(xiàn)得越好。此處表原因，故填because。9with考查介詞。be associated with為固定搭配，意為“與有聯(lián)系”，故填with。10better考查形容詞的比較級(jí)?！皌he比較級(jí)，the比較級(jí)”為常用句式，意為“越，越”，故填better。*完形填空。Something quite tragic(悲劇的)happened in our home.It had a _1_ effect on our lives.It

v發(fā)生1D根據(jù)上下文可知，家里沒有WiFi對(duì)我們生活的影響是巨大的(huge)。possible“可能的”；modest“謙虛的”；positive“積極的”。2B根據(jù)前一句“It had a _1_ effect on our lives”和下文的“But，what will we do”可知，平時(shí)家里離不開WiFi，現(xiàn)在沒有了，當(dāng)然對(duì)我們平時(shí)的生活方式產(chǎn)生挑戰(zhàn)。explore“探索”；improve“提升”；guarantee“保證”。3C根據(jù)下文的“When given the news that there was no WiFi in the house”可知，我們家里失去(lost) WiFi一個(gè)多星期；receive“收到”；book“訂購”；buy“購買”。4B根據(jù)第二段第一句“I was raised in the preWiFi era”可知，“我”是在沒有WiFi的時(shí)代長大的，因此對(duì)于沒有了WiFi也是比較習(xí)慣的(accustomed)，be accustomed to表示“習(xí)慣于”。5A根據(jù)上下文可推知，“我”習(xí)慣無WiFi的生活，但是孩子們不習(xí)慣。上下文是轉(zhuǎn)折關(guān)系，因此選however。6C根據(jù)空后的“But, what will we do”可知空處指的是他們的第一反應(yīng)(response)。7D根據(jù)上下文可知，沒有WiFi只有電視，且電視頻道只有70多個(gè)，孩子們很絕望。excited“興奮的”；grateful“感激的”；embarrassed“尷尬的”；desperate“絕望的”。8B根據(jù)本句的定語從句“most of which is now given online”可知，家庭作業(yè)應(yīng)是孩子們的主要(major)挑戰(zhàn)。avoidable“可避免的”；enjoyable“令人愉快的”；simple“簡單的”。9A空后的“the dog ate my homework”表示“狗吃了我的作業(yè)”，此處表示沒有網(wǎng)絡(luò)是這種借口的一個(gè)新提法，故選A。10C根據(jù)空后的賓語從句“that one of her friends had her water supply temporarily_11_ due to a leak”可知，這些內(nèi)容應(yīng)該是女兒講出來(observed)的。 repeat“重復(fù)”；promise“承諾”；ignore“忽略”；observe“觀察，說，評(píng)論”。11B根據(jù)該空后的“due to a leak”可推知，水管漏水了，供水會(huì)被暫時(shí)中斷(cut off)。12A根據(jù)上下文可知，女兒認(rèn)為我們沒有WiFi更糟糕(worse)。13D根據(jù)上下文可知，為了能夠在家工作，丈夫和“我”需要互聯(lián)網(wǎng)。enable sb.to do sth.表示“使某人能做某事”。14C根據(jù)下文的“Although expensive”可知，“我”去商店買(purchase)WiFi。 look into“調(diào)查”；search for“尋找”；borrow“借”。15A根據(jù)語境可知，買了WiFi，“我”建立自己的網(wǎng)絡(luò)就容易了。16D根據(jù)本句中的“l(fā)ike leaving a tap running(像讓水管的水不停地流著一樣)”可知，我們知道讓水管的水不停地流著意味著“浪費(fèi)”，故選D。17B根據(jù)上下文可知，當(dāng)“我”上網(wǎng)做事時(shí)，“我”是盡快地做，as quickly as possible表示“盡快地”。18A根據(jù)語境可知，技術(shù)已經(jīng)引起了我們?nèi)粘Ｉ畹母淖儯@些改變?cè)谖覀儧]有注意(noticing)的情況下發(fā)生了。19D參見上題解析。reflect“反思”；hear“聽到”；appreciate“欣賞”。20C根據(jù)該空后的“without WiFi was seeing the children make forts(堡壘)out of the sofa cushions，which they havent done in years”可知，沒有了WiFi，孩子們可以在一起玩，這是愉快的(bright)事情。*短文改錯(cuò)。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.

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難項(xiàng)分析：第二處：taketakes此處together with后的名詞不影響謂語動(dòng)詞的數(shù)，句子的主語是learning，謂語動(dòng)詞用第三人稱單數(shù)形式，故改為takes。第七處：rubbishesrubbishrubbish表示“垃圾”，是不可數(shù)名詞，沒有復(fù)數(shù)形式，故改為rubbish。第九處：去掉of此處指使我們的家鄉(xiāng)變得更加美麗。根據(jù)句中的“more”可知，此處修飾比較級(jí)，表示程度，故應(yīng)用a lot。a lot of表示“許多”，修飾名詞。
