課時(shí)17 書面表達(dá)（五）-求助信 .閱讀理解AEver feel like youve been hit on the head after a bad nights sleep？ According to scientists， the thought isnt as unbelievable as it seems.A study found going without sleep for just one night causes changes in the brain similar to those that occur after a blow to the head. The researchers said the healthy young men examined in the study showed a sudden increase in the same chemicals which indicate brain damage. Professor Christian Benedict， of Uppsala University， Sweden， explained that the chemicals NSE and S100B are biomarkers (生物指標(biāo)) for brain damage， such as concussion(腦震蕩). He said， “What we found was their levels in the blood rose in the group that went without sleep for a night. This was not to the extent that would happen after a head injury， for instance， but it was still significant. During sleep， the brain cleans poisonous substances off itself.”Benedict also said previous studies which linked a lack of sleep with increased risk of Alzheimers， Parkinsons and multiple sclerosis could applaud his study. The rise of the chemicals in the blood after sleep loss may suggest not getting enough sleep contributes to a loss of brain tissue， he explained. Benedict， whose study is published in the journal Sleep， added， “In conclusion， the findings of our experiment indicate a good nights sleep may be critical to maintaining brain health.”A third of the UK population suffer from sleeprelated problems， while the average person now sleeps for only seven hours a night， compared with almost nine a few decades ago. Many scientists believe irregular sleeping patterns lead to illnesses ranging from aches and pains to heart disease， while less than eight hours sleep a night can lower the IQ the next day.語(yǔ)篇解讀本文是一篇科普類說(shuō)明文?？茖W(xué)家們發(fā)現(xiàn)，睡眠不足對(duì)大腦造成的損傷接近頭部重?fù)簟２蛔惆诵r(shí)的睡眠甚至?xí)档偷诙斓闹巧獭?.If you dont sleep for a night， what will happen？A.NSE and S100B will increase.B.The brain damage will be like a head injury.C.You will suffer from concussion.D.The brain will get rid of poisonous substances.解析：考查細(xì)節(jié)理解。文章第二段的“What we found was their levels in the blood rose in the group that went without sleep for a night”中的their指的就是前面提到的“the chemicals NSE and S100B”，由此可知，一晚上不睡覺的話，血液中的化學(xué)物質(zhì)NSE和S100B就會(huì)增加。答案：A2.What do we know about previous studies？A.They found reasons for brain disorders.B.Their findings were published in Sleep.C.They were supported by Benedicts study.D.They focused on brain health.解析：考查推理判斷。根據(jù)第三段中的“Benedict also said previous studies which linked a lack of sleep with increased risk of Alzheimers， Parkinsons and multiple sclerosis could applaud his study”可知，Benedict說(shuō)先前的研究會(huì)贊成他的研究，接著Benedict解釋了為什么先前的研究會(huì)贊成他的研究，即“The rise of the chemicals in the blood after sleep loss may suggest not getting enough sleep contributes to a loss of brain tissue”。綜上可推知，Benedict的研究支持了先前的研究。答案：C3.What can we infer from the last paragraph？A.UK people have the worst sleep.B.Mans intelligence is affected by sleep in a way.C.People were smarter in the past.D.A lack of sleep causes all brainrelated problems.解析：考查推理判斷。根據(jù)文章最后一段中的“l(fā)ess than eight hours sleep a night can lower the IQ the next day”可知，睡眠少于八小時(shí)的人第二天智商會(huì)降低，這暗示人的智力在某種程度上受睡眠的影響。故B項(xiàng)正確。答案：B4.Whats the main idea of the passage？A.Eight hours sleep is important.B.Regular sleeping patterns improve health.C.Sleep loss is close to a blow to the head.D.Human brains work during sleep.解析：考查主旨要義。根據(jù)文章內(nèi)容，尤其是第一段及第二段的首句可知，本文主要圍繞“睡眠不足對(duì)大腦造成的損傷接近于頭部遭重?fù)簟边@一主題展開。故C項(xiàng)最能概括文章的大意，而其他選項(xiàng)都比較片面。答案：CBIt seems that the great desire among the young is to be popular. The desire to be popular can force you into looking and acting like everyone else. You can lose yourself in a sea of identical hairstyles and thinking styles.I was forced to think about popularity not too long ago in a talk I had with my daughter. Margy had to change schools when my busy work schedule made it necessary for me to move houses. I suppose that， for a girl in her teens， entering a new school is like spending a season alone in the tropical jungles. At least thats how Margy found it at first. However， as the school year drew to a close， one student after another came to her. I told Margy that I would have been more concerned if she had been an instant social success in her new school. Nobody can please everyone. If you try to do so， you will find values as lasting as soap bubbles blown into the air.Some teenagers claim they want to dress as they please. But they all wear the same clothes. They set off in new directions in music. But somehow they all end up listening to the same record. Their reason for thinking or acting in a certain way is that the crowd is doing it. They have come out of their cocoon into a larger cocoon.I know that it has become harder for a young person to stand up against the popularity wave. Our way of life makes a young nonconformist stand out like a Martian. These days theres a great barrier for the young person who wants to find his or her own path. But the barrier is worth climbing over. You may want to listen to classical music instead of going to a party. Well， go to it. Be yourself. Popularity will come with the people who respect you for who you are. Thats the only kind of popularity that really counts.語(yǔ)篇解讀本文作者從自己女兒換了新學(xué)校后迅速受到新同學(xué)歡迎的事實(shí)談起，批判了那些為迎合他人而放棄自我的行為方式，并就“受歡迎”表達(dá)了自己的觀點(diǎn)：做真實(shí)的自己，別人也會(huì)尊重你的本真。5.Why was the author worried about his daughters popularity in her new school？A.She might find no true friends.B.She would ignore her academic performance.C.She had no idea of her own.D.She might betray her true self.解析：考查推理判斷。第一段提到為了受歡迎而一味迎合別人的人“can lose yourself in a sea of identical hairstyles and thinking styles”，再由第二段中的“Nobody can please everyone. If you try to do so，you will find values as lasting as soap bubbles blown into the air”可知，作者認(rèn)為如果他的女兒在新學(xué)校已取得人際交往上的即刻成功的話，那么對(duì)作者來(lái)說(shuō)，女兒肯定是違背了真實(shí)的自我以取悅他人，使自己變得受歡迎。因此，答案選D。答案：D6.What does the author think of most teenagers？A.Theyre afraid of getting lost in life.B.They have difficulty understanding each other.C.They lack the courage to be truly different.D.They find it hard to gain popularity as expected.解析：考查推理判斷。由第三段的內(nèi)容可知，一些青少年想要隨心所欲地穿衣搭配，但卻和大多數(shù)人穿得一樣；一些人在音樂方面想走不同的路，但最終卻還是和大多數(shù)人聽一樣的歌；他們用某種方式思考或做事是因?yàn)榇蠹叶寄菢幼?。由此推斷，作者認(rèn)為大多數(shù)青少年缺少真正變得與眾不同的勇氣。因此，答案選C。答案：C7.What is the probable meaning of the underlined word “nonconformist” in Paragraph 4？A.Someone who cares about others opinion.B.Someone who desires popularity greatly.C.Someone who behaves in his own way.D.Someone who wants to please others.解析：考查詞義猜測(cè)。由第四段中的“I know that it has become harder for a young person to stand up against the popularity wave”可知，此處指想要變得與眾不同，走自己的路變得更難了。由此可推知畫線詞“nonconformist”指的應(yīng)是“不遵循常規(guī)的人”。因此，答案選C。答案：C8.What is the authors purpose of writing this passage？A.To persuade readers to pursue valuable popularity.B.To tell parents how to guide their children.C.To criticize the present values and beliefs.D.To suggest a good way to be popular.解析：考查寫作目的。由全文內(nèi)容可知，作者從自己女兒換了新學(xué)校后迅速受到新同學(xué)歡迎的事實(shí)談起，批判了那些為迎合他人而放棄自我的行為方式，并就“受歡迎”表達(dá)了自己的觀點(diǎn)：做真實(shí)的自己，別人也會(huì)尊重你的本真。因此，作者的寫作目的在于勸誡讀者追求有價(jià)值的“受歡迎”，而不要去一味地迎合他人。因此答案選A。答案：A.完形填空The little boy stood outside the entrance to the mall， in the _1_ wind， collecting donations for cancer research.
