The Olympic Games ***閱讀理解 Crossing your legs is an extremely mon habit; most people don’t even notice that they’re 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 won’t 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? Don’t 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 ankle—what 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(yǔ)】　本文是一篇科普說(shuō)明文。研究表明，雖然蹺二郎腿是常見(jiàn)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。 1．What can we learn about crossing one’s legs? A．It is a very bad social habit. B．It is usually practiced deliberately. C．It can do harm to people’s health. D．It 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(wèn)題，故C項(xiàng)正確。 2．According to the study, sitting with your legs crossed can ． A．a(chǎn)ffect your blood pressure B．resist gravity effectively C．lead to heart attacks easily D．improve the function of legs A　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。 3．In the third paragraph “pins and needles” probably means “ ”． A．slightly sharp pains B．being a little tired C．serious muscle injuries D．being highly flexible A　解析：詞義猜測(cè)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(wú)法站立，有一種針刺感；據(jù)此可以判斷，畫(huà)線詞意為“輕微的針刺感似的疼痛”，故A項(xiàng)正確。 4．What is the main purpose of the text? A．To pare mon habits. B．To give readers some advice. C．To evaluate the effects of an experiment. D．To introduce research methods. B　解析：寫(xiě)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(guò)分析蹺二郎腿這一習(xí)慣導(dǎo)致的健康問(wèn)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(yǔ)法填空 Do you make friends __1__(easy)? Do a wallsit test and youll find out.

Participants first __3__(fill) out questionnaires about their social lives, and they were then asked __4__ (press) against a wall with their __5__(knee) at right angles (直角) for as long as they could, __6__can be really painful. The results showed that the longer the participants held the position, the bigger __7__(they) outer network—or distant friends they contacted once or twice a month—was. That was__8__the brains painkilling system is associated__9__both pain tolerance and social bonding, which means that the more active this system is, the __10__(good) you are at both. 1．________ 　2.________ 　3.________ 　4.________ 　5.________ 　6.________ 　7.________ 　8.________ 　9.________ 　10.________ 篇章導(dǎo)讀：本文是一篇說(shuō)明文。文章介紹了一項(xiàng)和交友有關(guān)的調(diào)查，具體方法如下：身體貼墻，膝蓋彎曲成直角，根據(jù)保持這個(gè)姿勢(shì)的時(shí)間長(zhǎng)短可以推斷出你的社交能力。 1．easily　考查詞性轉(zhuǎn)換。此處修飾動(dòng)詞短語(yǔ)make friends，所以要用副詞，故填easily。 2．a(chǎn)　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。 3．filled　考查動(dòng)詞的時(shí)態(tài)。句意：參與者首先填寫(xiě)了關(guān)于他們的社交生活的問(wèn)卷，然后他們被要求盡可能長(zhǎng)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(yǔ)動(dòng)詞，而且是描述過(guò)去的事情，所以用一般過(guò)去時(shí)，故填filled。 4．to press　考查非謂語(yǔ)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。 5．knees　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。 6．which　考查定語(yǔ)從句的引導(dǎo)詞。設(shè)空處引導(dǎo)非限制性定語(yǔ)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(yǔ)，故填which。 7．their　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。 8．because　考查表語(yǔ)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。 9．with　考查介詞。be associated with為固定搭配，意為“與……有聯(lián)系”，故填with。 10．better　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 __2__ the way we relax and even where we sit.There was no fire or flood...we __3__ our WiFi service，for over a week.

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 難項(xiàng)分析： 第二處：take→takes　此處together with后的名詞不影響謂語(yǔ)動(dòng)詞的數(shù)，句子的主語(yǔ)是learning，謂語(yǔ)動(dòng)詞用第三人稱單數(shù)形式，故改為takes。 第七處：rubbishes→rubbish　rubbish表示“垃圾”，是不可數(shù)名詞，沒(méi)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。
