4.A man looking at his smartphone while walking across a railway crossing in Nanjing (61)had (have) a close knock on Oct 22.He was so (62)absorbed(absorb) in his smartphone that he didn't see a train approaching until it brushed past him,(63)throwing(throw) him to the ground.This should serve  (64)as a warning that people should be aware of their surroundings,especially (65)when/while crossing roads.
(66)Luckily(lucky),the man survived,but the incident forced the driver (67)to stop(stop) the train.An l8-minute delay followed the incident,(68)which led to a break in the running of other trains on the route.
The Smartphone (69)addiction(addict) has spread like an infectious(傳染的)disease.It's evident that it will do great harm to society.What's even (70)worse (bad),some addicts become impatient with relatives and friends.
Some people blame the smartphone for the sad story,yet in fact people's weakening self-control and self-discipline are to blame.

分析 本文通過一次事故來說明目前很多行人會對手機(jī)入迷以至于帶來很多安全隱患.

解答 61.had       考查動詞.句子里on Oct 22講述過去的事情,所以用一般過去時.
62.a(chǎn)bsorbed   考查形容詞.be absored in 為固定短語,對…入迷.
63.throwing   考查現(xiàn)在分詞.throw此處表示現(xiàn)在分詞做狀語,表示結(jié)果.
64.a(chǎn)s       考查介詞.sever as 為固定短語.
65.when/while    考查連接詞.when當(dāng)…時候,當(dāng)過馬路的時候.
66.Luckily  考查副詞.修飾整個句子需用副詞形式.
67.to stop    考查動詞不定式.force sb to do sth為固定短語,強(qiáng)迫某人做某事.
 68.which      考查連接詞.分析句式可知which引導(dǎo)一個非限制性定語從句,指前面提到的這件事情.
69.a(chǎn)ddiction     考查名詞.此處做句子主語需用名詞形式.
70.worse 考查比較級.進(jìn)一步說明對手機(jī)上癮所帶里的危害.

點(diǎn)評 語法填空對學(xué)生要求比較高,平時多積累一些語法知識并在具體語境中靈活使用.

9.At the beginning of my 8:00 a.m.class one Monday at UNLV(拉斯維加斯內(nèi)華達(dá)大學(xué)),I cheerfully asked my students how their weekend had been.One young man said that his weekend had not been very good.The young man then proceeded to ask me why I always seemed to be so cheerful.
His question reminded me of something I'd read somewhere before:"Every morning when you get up,you have a choice about how you want to approach life that day,"I said to the young man."I choose to be cheerful."
"Let me give you an example,"I continued."In addition to teaching here at UNLV,I also teach out at the community college in Henderson,about seventeen miles down the freeway from where I live.One day a few weeks ago I drove to Henderson.I exited the freeway and turned onto College Drive.But just then my car died.I tried to start it again,but the engine wouldn't turn over.So I put my flashers on,took my books,and marched down the road to the college."
"As soon as I got there,I called AAA(美國汽車協(xié)會) and asked them to send a tow truck (拖車).The secretary in the Provost's office asked me what had happened.'This is my lucky day',I replied,smiling."
"Your car breaks down and today is your lucky day?"She was puzzled,"What do you mean?"
"I live seventeen miles from here".I replied."My car could have broken down anywhere along the freeway.It didn't.Instead,it broke down in the perfect place:off the freeway,within walking distance of here.I'm still able to teach my class,and I've been able to arrange for the tow truck to meet me after class.If my car was meant to break down today,it couldn't have been arranged in a more convenient fashion."

13.March 21has been declared World Sleep Day,a time to recognize and celebrate the value of sleep.Many sleep experts hope it will be a wake-up call.
According to a 2013poll(民意調(diào)查) by the National Sleep Foundation,nearly 4in 5Americans don't get as much sleep as they should during the workweek.On average,adults are thought to need at least eight hours of sleep a night,although some can manage with less and some won't do well without more.But the survey found that,on workdays,only 21% of Americans actually get a full eight hours of sleep,and another 21% get less than six.
To many of us,the thought of spending more time sleeping is,well,a big yawn.On the other hand,the thought of being smarter,thinner,healthier and more cheerful has a certain appeal.And those are just a few of the advantages that can be ours if we consistently get enough sleep,researchers say.Also on the plus side:We're likely to have better skin,better memories,better judgment,and,oh,yes,longer lives.
"When you lose even one hour of sleep for any reason,it influences your performance the next day,"says Dr.Alon Avidan,director of the UCLA Sleep Disorders Center.
A study published last year found the same to be true even of children.When kids aged 8to 12slept for just one hour less for four nights,they didn't function as well during the day.
But sleeping has an image problem."We see napping or sleeping as lazy,"says Jennifer Vriend,a clinical psychologist in Ottawa,Canada,and the leading author of the study with children."We put so much emphasis on diet,nutrition and exercise.Sleep is in the back seat."In fact,she adds,no matter how much we work out,no matter how well we eat,we can't be in top physical shape unless we also get plenty of sleep.

56.The underlined part in Paragraph 1meansC.
A.to wake up the sleepers
B.to serve as a morning call
C.to draw people's attention
D.to declare the special day
57.Which of the following is True according to Paragraph 2?B
A.People can do well without enough sleep.
B.Adults need at least eight hours'sleep a day.
C.Only one-forth of Americans have enough sleep.
D.One-fifth of American adults sleep less than children.
58.From Paragraph 3we can infer thatC.
A.being healthier is one of the advantages for us
B.sleeping has nothing to do with one's expectations
C.enough sleep is the guarantee of the appealing things
D.spending more time on sleeping is a waste of time
59.What Jennifer Vriend said in the last paragraph implies thatA.
A.people care little about sleeping
B.sleeping is an image problem
C.lazy people tend to sleep long
D.sleeping is only part of our life
60.What is the purpose of the passage?D
A.To talk about people's sleeping problems.
B.To provide an investigation result of sleeping.
C.To stress the function of sleeping at night.
D.To arouse the awareness of enough sleeping.
