7.Your smart-phone(智能手機) can do a lot of things.It can call people.It connects to the Internet.It enables you to play fun games.But there is a dark side to this smart little device of yours-it might also spread disease.
"People are just as likely to get sick from their phones as from handles of the bathroom,"Jeffery Cain,the president of the American Academy of Family Physicians,told The Wall Street Journal.
This may be hard to believe,but scientists reached this conclusion after they tested eight random cell phones from an office in Chicago.All the tested phones showed high numbers of coli forms(大腸菌),a kind of bacteria found in excrement(糞便),with about 2,700 to 4,200 units of the bacteria on each phone.In drinking water,the healthy limit is less than 1 unit per 100 ml of water.This bacteria can cause flu,pinkeye(紅眼。 and diarrhea(腹瀉).That's right-your phone is covered with excrement!
Although computers,keys and pens all carry bacteria,our smart-phones get far dirtier.They touch a lot of stuff,including our pocket or purse.We take them almost everywhere:the bus,the subway and who hasn't played Angry Birds or Fruit Ninja while sitting on the toilet?
"Some things that we think are personal are actually more public than we imagine,"Cain said.
What's even worse is that after the phone returns from its dirty trip,it then spends most of its time covering our faces.Our noses,mouths and ears are all warm and rich in grease(油脂),an environment that bacteria really like.
Compared to traditional keypads,touch screens spread bacteria more easily to hands.According to Time magazine's website,an expert in Australia warned that playing with iPads and iPhones at Apple stores is a health risk.
 
26.The underlined word"dark"in the first paragraph meansD.
A.black        B.hopeless         C.unclear          D.unpleasant
27.Which of the following best describes the tone of the third paragraph?C
A.Angry.B.Interested.C.Concerned.D.Delighted.
28.By saying"Some things we think are personal are actually more public than we imagine"in Paragraph 5,Cain meant thatC.
A.people love to share their smart-phones more than they realize
B.our personal items could be as risky to our health as public items
C.smart-phones are used in public places more than people realize
D.most people don't know how dirty their cell phones are
29.Compared with traditional keypads,smart-phonesB
A.a(chǎn)re greasier and need more alcohol to clean
B.make contact with our hands more often
C.get warm more easily and are harder to clean
D.get much nearer to our faces
30.What is the article mainly about?B
A.Tips on the use of smart-phones.
B.Health problems caused by the use of smart-phones.
C.The danger of coli forms infection.
D.The influence that smart-phones have on our life.

分析 本文屬于說明文閱讀,作者通過這篇文章主要向我們描述了手機上帶有太多的細菌,導致我們會出現(xiàn)很多的健康方面的問題.

解答 26.D.推理判斷題.根據(jù)文章第一段It can call people.It connects to the Internet.It enables you to play fun games.But there is a dark side to this smart little equipment of yours-----it might also spread disease.可知手機有很多的作用,但是手機也有很多的dark sides也就是說手機也有很不好的地方.故選D.
27.C.推理判斷題.在文章第三段里,作者描述了我們的手機上有太多的細菌,作者是用一種很擔心的心情在描述這樣的事情,因為手機是我們經(jīng)常使用的東西,上面如此臟,會對我們的健康也會有影響.故選C.
28.C.推理判斷題.根據(jù)本句"Some things that we think are personal are actually more public than we imagine,"可知很多事情比我們個人想象的還要復雜.在本文的具體語境中就是說我們使用手機的頻率比我們想象的還要高.故C正確.
29.B.細節(jié)理解題.根據(jù)倒數(shù)第二段:Compared to traditional keypads,touch screens spread bacteria more easily to hands可知與傳統(tǒng)的手機相比智能手機與我們的手經(jīng)常接觸;故選B.
30.B.主旨大意題.本文主要講述的手機上帶有太多的細菌,導致我們會出現(xiàn)很多的健康方面的問題.故B正確.

15.An English saying goes:"All work and no play makes Jack a dull boy."That means we should relax after a day's hard work or we'll be unhealthy.
Many students know that if they want to get ideal jobs with good salaries,they must do well in high school so they can enter good universities.Therefore,they spend all day studying without time to relax.
However,not all students can go to top universities even if they work very hard.Students are pressurized by parents and teachers who are just concerned about their studies and exam scores while ignoring their hobbies and individual differences.As a result,students are forces to work harder and harder.Furthermore,there is pressure coming from students themselves.They realize they have a slim chance of getting into a top university as competition is fierce.So,they put a lot of stress on themselves and stay in a nervous state day after day.If they keep it up,they'll suffer illnesses; both psychological and physical.
What students need is relaxation.This doesn't mean that they should give up their ambitions and stop studying hard.It means"work while you work,play while you play".If you can do this,you will improve your health greatly.You'll feel yourself suddenly fresh,just like recovering from a terrible illness.You'll find that your studies are not a burden(負擔) anymore.

63.The underlined part in the first paragraph might mean all the following EXCEPTD.
A.too much work may bring trouble to anyone
B.overwork without rest is sure to make one foolish
C.Jack becomes dull because he works too much
D.Anyone who doesn't work will break down
64.What trouble have both the parents and teachers brought to the students?B
A.They don't know how to let the students relax.
B.They give too much burden for them to bear.
C.They don't love those who work the hardest.
D.They fail to understand what the students need most.
65.What causes the student'pressure from themselves?C
A.That they don't know how to get top universities.
B.That they want to relax but have no chance.
C.That they fail to relax themselves during their work.
D.That they think too much about the result of their work.
66.What is the passage mainly about?D
A.What to do to relax yourself.
B.The serous situation for the poor students.
C.Some problems caused by the misunderstanding of learning.
D.How to be a healthy and successful learner.

2.When you get tense(緊張的) about something that happens in your life,you are experiencing stress.Too much stress can cause anger,depression and other related symptoms,which you need to seriously look into.
The following are simple ways that can be used to deal with stress.
Be Gentle with Yourself
There are times when you are not fair to yourself.Often you are harder on yourself than you are of other people.If you can learn to accept yourself just the way you are,especially unconditionally,this would reduce the pressure you apply to yourself.
Exercise
Go for a walk.Go to the shops.You can join a local walk,swim or jog team.If you are tired out from doing housework and haven′t left your workstation,have a stretch.Change your environment for an hour or so.
Stop Comparing Yourself with Others
Often you don′t realize that a great deal of unhappiness is caused by constant comparisons you make.You says,"if only I had a big house like she was…","if only my husband were as rich as hers…"The comparison is endless.The only comparison that counts is the comparison between where you were and where you are now.By all means,admire others,congratulate them and be proud of their achievements,but remind yourself that only you can decide the standard(標準) you want to set for yourself.
Talk the Stress Out
Sometimes it helps to share or talk about your stress to close friends or family members.The other person′s active listening can help.

25.The passage is mainly aboutB.
A.doing exercise is good for you health
B.how to deal with stress in life
C.comparing yourself with others is wrong
D.how to lead a happy life in daily life
26.According to the fifth paagraph,we shouldC.
A.make comparisons with others constantly
B.remind yourself that you're unhappy

PAI researcher Robert Engelman says by the year 2025,about 3,000million people may lack water.At least 18more countries are expected to have severe water problems.The demand for water keeps increasing.Yet the amount of water on Earth stays the same.

The PAI study gives several solutions(解決辦法)to the water problem.One way,it says,is to find ways to use water for more than one purpose.Another way is to teach people not to waste water.A third way is to use less water for agriculture.The report also says long-term solutions to the water problem must include controlling population growth.
