14.March 16th is World Sleep Day.This year's slogan (標(biāo)語(yǔ)) is"Breathe Easily,Sleep Well".Its aim is to celebrate the benefits of good and healthy sleep.
Sleep is like food for the brain.Enough sleep helps the body and brain grow and develop.According to the National Sleep Foundation in the US,adults need seven to nine hours of sleep every night.For students aged 10 to 17,a healthy amount is about eight to nine hours per night.
But many students don't get enough sleep because of early school start time and heavy homework.About 80 percent of middle school students don't get enough sleep,the China Youth and Children Research Center reported.For some students,they want to sleep early,but they keep worrying about their schoolwork and can't fall asleep quickly.For others,they may even have insomnia which might keep them awake (醒著的)all night.
These sleeping problems greatly affect people's lives.Experts have shown that lack of sleep for teenagers leads to poor grades.Students without enough sleep cannot pay attention in class or do well in sports.Also,the lack of sleep may make them depressed (沮喪的).
Luckily,with good sleeping habits,it is easier to fall asleep.Some of these good habits include avoiding drinks that make people excited late in the day,going to sleep at the same time each night,and sleeping in a comfortable place that is dark,quiet,and neither too warm nor too cold.

12.If Li Hong is 15 years old,how much sleep does she need every night?B
A.10-12 hours.
B.8-9 hours.
C.7 hours.
D.Less than 7 hours.
13.What might happen if teenagers don't get enough sleep?C
A.They might do well in sports.
B.Their bodies and brains might grow better.
C.They might feel depressed.
D.They might not be able to finish their schoolwork.
14.The underlined word"insomnia"means"D"in Chinese.
A.健忘癥     
B.肥胖癥     
C.多動(dòng)癥   
 D.失眠癥
15.Which of the following are good sleeping habits?C

b.Going to bed at the same time.
c.Sleeping in a dark and quiet place.
d.Drinking something that makes you excited.

D.b-d.

分析 三月十六日是世界睡眠日.今年的口號(hào)是"呼吸輕松,睡個(gè)好覺(jué)".充足的睡眠有助于身體和大腦生長(zhǎng)的發(fā)育.根據(jù)調(diào)查成人需要每晚睡九小時(shí).10至17歲的學(xué)生,大約需要是八到九小時(shí).但許多學(xué)生沒(méi)有得到足夠的睡眠,因?yàn)樗麄冇蟹敝氐募彝プ鳂I(yè).這些睡眠問(wèn)題對(duì)人的生活有很大的影響.專(zhuān)家表明,青少年缺乏睡眠將導(dǎo)致成績(jī)差,同時(shí),缺乏睡眠也會(huì)使他們沮喪.

解答 12.B 細(xì)節(jié)理解題.根據(jù)第二段的For studentsaged 10 to 17,a healthy amountis about eight to nine hours per night.可知,對(duì)于10至17歲的學(xué)生,健康的睡眠數(shù)量大約是每晚八到九個(gè)小時(shí).故選B.
13.C 細(xì)節(jié)理解題.根據(jù)第四段的Students withoutenough sleep cannot pay attention in class or do well in sports.Also,the lack ofsleep may make them depressed (沮喪的).可知,沒(méi)有足夠睡眠的學(xué)生在課堂上不能集中注意力,也不能在運(yùn)動(dòng)中表現(xiàn)良好,而且,睡眠不足可能使他們沮喪.所以睡眠不足的青少年可能會(huì)感到沮喪,故選C.
14.D 詞義猜測(cè)題.根據(jù)后面的定語(yǔ)從句which might keepthem awake all night可知,能讓他們保持整夜清醒的應(yīng)是"失眠癥",故選D.
15.C 細(xì)節(jié)理解題.根據(jù)最后一段的Some of thesegood habits include avoiding drinks that make people excited late in the day,going to sleepat the same time each night,and sleeping in a comfortable place that is dark,quiet,and neither toowarm nor too cold.可知,這些良好的習(xí)慣包括:避免讓人興奮的飲料,在每晚同一時(shí)間睡覺(jué),睡在一個(gè)黑暗、安靜、既不太熱也不太冷的舒適的地方.故選C.

點(diǎn)評(píng) 本文是歷史文化類(lèi)閱讀,主要考查細(xì)節(jié)理解題和推理判斷題.在做細(xì)節(jié)理解題時(shí),首先根據(jù)題目要求迅速在文章里找出相應(yīng)的段落、句子或短語(yǔ).認(rèn)真比較選項(xiàng)和文中細(xì)節(jié)的區(qū)別,在做推理判斷題時(shí)不要以個(gè)人的主觀想象代替文章的事實(shí),要根據(jù)文章事實(shí)進(jìn)行合乎邏輯的推理判斷.

4.A woman renewing her driver's license at the County Clerk's office was asked to state her occupation.She hesitated,uncertain how to classify herself.
"What I mean is,"explained the recorder,"do you have a job,or are you just a …"
"Of course I have a job,"said Emily."I'm a mother."
"We don't list‘mother'as an occupation…‘housewife'covers it,"said the recorder.
    One day I found myself in the same situation.The clerk was obviously a career woman,confident and possessed of a high sounding title."What is your occupation?"she asked.
    The words simply popped out."I'm a Research Associate in the field of Child Development and Human Relations."
    The clerk paused,ballpoint pen frozen in midair.
    I repeated the title slowly,and then I stared with wonder as my statement was written in bold,black ink on the official questionnaire.
"Might I ask,"said the clerk with new interest,"Just what you do in this field?"
    Without any trace of panic in my voice,I heard myself reply,"I have a continuing program of research (what mother doesn't),in the lab and in the field (normally I would have said indoors and out).Of course,the job is one of the most demanding in the humanities (any mother care to disagree?),and I often work 14 hours a day (24 is more like it).But the job is more challenging than most careers and rewards are more of a satisfaction rather than just money."
    There was an increasing note of respect in the clerk's voice as she completed the form,stood up,and showed me out.
    As I drove into our driveway,buoyed up (依托) by my glamorous new career,I was greeted by my lab assistants---ages 13,7,and 3.
    Upstairs I could hear our new experimental model (a 6 month old baby),in the child-development program,testing out a new vocal pattern.
    I felt proud!I had gone on the official records as someone more distinguished and indispensable (不可缺少的) to mankind than"just another mother."
    Motherhood…What a glorious career!Especially when there's a title on the door.
9.How did the female clerk feel at first when the author told her occupation?B
A.curious     
B.puzzled     
C.indifferent     
D.interested
10.How did the author feel when describing her job to the clerk?A
A.calm    
B.funny     
C.worried     
D.cool
11.Wh y did the woman clerk show more respect for the author?C
A.Because the author cared little about rewards.
B.Because she admired the author's research work in the lab.
C.Because she thought the author did admirable work.
D.Because the writer did something she had little knowledge of.
12.What is the author's purpose of writing the passage?B
A.To show how you describe your job affects your feelings toward it.
B.To argue that motherhood is a worthy career and deserves respect.
C.To show that the author had a grander job than Emily.
D.To show that being a mother is hard and boring work.
