5.When a computer works on a group of programs,it can get very hot.Cooling the computer can
cost a lot.So some scientists wonder what would happen if the heat from the computer could be used.
Large Internet companies (公司) such as Google and Microsoft have thousands of computers.As these computers deal with information,they produce lots of heat,so they need huge cooling systems (系统).These systems send the heat into the air.
A company in Holland (荷兰) thinks paying to make the computers work and then paying again to cool them are a waste of energy.So the company developed a special device-the e-Radiator.
Boaz Leupe,head of the company,says that e-Radiator works as a heating system and saves money.He explains that the energy is used twice-once to heat the home and once to cool the computer and that the users don't have to pay to cool their computers.
Five homeowners in Holland are testing the heating system in their homes."We pay for the computer using,so,in that way,homeowners get heating for free,"Boaz says.
Jan Visser is one of the homeowners."If you use the computer more,the e-Radiator producers more heat,"he says,"It cannot provide enough heat if you don't use your computer often."But he is ready to try it.It's a great help for his family.
The company says e-Radiators produce heat temperatures of up to 55℃.It says the system could save its users about﹩440a year.

32.The e-radiator is mainly usedA.
A.to provide heat  
B.to drive the computer
C.to heat the computer  
D.to help Microsoft
33.Before the e-Radiator appears,usually the heat of a computerD.
A.makes the computer work better     
B.helps the five homeowners
C.is used twice                    
D.is sent into the air
34.The Chinese meaning of the word"device"in this passage is probably"B".

3.Bicycle Safety
Operation  Always ride your bike in a safe,controlled manner on campus(校园).Obey rules and regulations.Watch out for walkers and other bicyclists,and always use your lights in dark conditions.
Theft Prevention  Always securely lock your bicycle to a bicycle rack---even if you are only away for a minute.Register your bike with the University Department of Public Safety.It's fast,easy,and free.Registration permanently records your serial number,which is useful in the possible recovery of the bike stolen.
Equipment
Brakes  Make sure that they are in good working order and adjusted properly.
Helmet  A necessity,make sure your helmet meets current safety standards and fit properly.
Lights  Always have a front headlight---visible at least 500 feet in front of the bike.A taillight is a good idea.
Rules of the Road
Riding on Campus  As a bicycle rider,you have a responsibility to ride only on streets and posted bicycle paths.Riding on sidewalks or other walkways can lead to a fine.The speed limit for bicycles on campus is 15mph,unless otherwise posted.Always give the right of ways to walkers.If you are involved in an accident,you are required to offer appropriate aid,call the Department of Public Safety and remain at the scene until the officer lets you go.
Bicycle Parking  Only park in areas reserved for bikes.Trees,handrails,hallways,and sign posts are not for bicycle parking,and parking in such posts can result in a fine.
If Things Go Wrong
If you break the rules,you will be fined.Besides violating rules while riding bicycles on campus,you could be fined for:
No bicycle registration---------------------------------------------------25
Bicycle parking banned--------------------------------------------------30
Blocking path with bicycle---------------------------------------------40

10.But while the constant repetition(重复)might be boring for mum or dad,it is the best way for toddlers (初学走路的孩子) to learn new words,according to a research.
The findings suggest parents are wasting money by spending a lot of money on huge book collections in the hope that they will inspire their children.
Instead,a small selection of favorites such as The Very Hungry Caterpillar or The Gruffalo will achieve far more.
Dr Jessica Horst of the University of Sussex's Word Lab carried out an experiment to check how quickly three-year-olds could recognize and recall(记起) six new words.
The children were visited three times in a week at their homes.One group heard the same story three times back-to-back each time and another was read three different stories.All had the same amount of new words which appeared the same number of times.
When researchers returned a week later,they found the children who heard the same story over and over had typically(通常)learned 3.6of the new words.
Those who heard different stories remembered only 2.6.They also noted the‘repetition'group learned at a faster rate than those in the‘variety'group.
Dr Horst said:"We are showing that less is more,to a point(在某种程度上).Obviously,the more times you read to a child and the more books you have will help them.But you don't need to go crazy and buy every single Thomas the Tank Engine book.Reading the same books over and over again helps."
Previous(以前的) studies have found parents spend just 49minutes doing things with their children each day.One in three don't read to their children before putting them to bed at night.Yet 30minutes of one-on-one literacy (一对一的读写能力) activities can improve reading age by nearly two years in less than five months.

28.Why do some parents buy lots of books for their children?B
A.They have got a lot of money.
B.Those books will be good for children.
C.Huge book collections will be cheap.
D.Children don't like a small selection.
29.What can we conclude from the experiment?A
A.The variety group learned fewer words.
B.The repetition group read more stories.
C.The variety group recalled words quickly.
D.The repetition group learned more slowly.
30.What do we know from the last paragraph?D
A.Parents needn't spend time with their children.
B.30minutes of reading activities is useless.
C.Reading age depends on children's night activities.
D.Reading to children each night is helpful for reading age.
31.Which of the following is the best title for the passage?C
A.The Repetition Group and the Variety Group.
B.Why Should Parents Buy Huge Book Collections?
C.The Best Way to Help Children Learn New Words.
D.Thirty Minutes of One-on-one Reading Activities.
4.Just as the teacher hands out the spelling test,you see Jeff pull out a small piece of paper with a lot of small words on it.Jeff hides the note into his hand but soon takes it out again.While he's taking the test,you see him looking back and forth between the teacher and his paper.There's no mistaking it-he's cheating.
Cheating can happen in a lot of different ways.When people cheat,it's not fair to other people,like the kids who studied for the test or who the true winners of a game were.
Many people like the action of cheating.It makes difficult things seem easy,like getting all the right answers on the test.But it doesn't solve the problem of not knowing the material and it won't help on the next test-unless the person cheats again.
Some people lose respect for cheaters and think less of them.The cheaters themselves may feel bad because they know they are not really earning that good grade.And,if they get caught cheating,they will be in trouble at school,and maybe at home,too.
Some kids cheat because they're busy or lazy and they want to get good grades without spending the time studying.Other kids might feel like they can't pass the test without cheating.Even when there seems to be a"good reason"for cheating,cheating isn't a good idea.
If you were sick or upset about something the night before and couldn't study,it would be better to talk with the teacher about this.And if you don't have enough time to study for a test because of swim practice,you need to talk with your parents about how to balance swimming and school.
A kid who thinks cheating is the only way to pass a test needs to talk with the teacher and his or her parents so they can find some solutions together.Talking about these problems and working them out will feel better than cheating.

A.it is unfair to other people         B.it does harm to their heath
C.teachers should punish them          D.teachers shouldn't stop them at once

5.Among the more colorful characters of Leadville's golden age were H.A.W.Tabor and his second wife,Elizabeth McCourt,better known as"Baby Doe".Their history is fast becoming one of the legends of the Old West.Horace Austin Warner Tabor was a school teacher in Vermont.With his first wife and two children he left Vermont by covered wagon in 1855to homestead in Kansas.Perhaps he did not find farming to his liking,or perhaps he was lured(诱惑) by rumors of fortunes to be made in Colorado mines.At any rate,a few years later he moved west to the small Colorado mining camp known as California Gulch,which he later renamed Leadville when he became its leading citizen."Great deposits of lead are sure to be found here."he said.
As it turned out,it was silver,not lead,that was to make Leadville's fortune and wealth.Tabor knew little about mining himself,so he opened a general store,which sold everything from boots to salt,flour,and tobacco.It was his custom to"grubstake"prospective miners,in other words,to supply them with food and supplies,or"grub",while they looked for ore(矿石),in return for which he would get a share in the mine if one was discovered.He did this for a number of years,but no one that he aided ever found anything of value.
Finally one day in the year 1878,so the story goes,two miners came in and asked for"grub".Tabor had decided to quit supplying it because he had lost too much money that way.These were persistent,however,and Tabor was too busy to argue with them."Oh help yourself.One more time won't make any difference,"He said and went on selling shoes and hats to other customers.The two miners took﹩17 worth of supplies,in return for which they gave Tabor a one-third interest in their findings.They picked a barren(贫瘠的)place on the mountain side and began to dig.After nine days they struck a rich vein of silver.Tabor bought the shares of the other two men,and so the mine belonged to him alone.This mine,known as the"Pittsburgh Mine,"made﹩1,300,000 for Tabor in return for his﹩17 investment.Later Tabor bought the Matchless Mine on another barren hillside just outside the town for﹩117,000.This turned out to be even more unbelievable than the Pittsburgh,yielding﹩35,000worth of silver per day at one time.Leadville grew.Tabor became its first mayor,and later became lieutenant(助理) governor of the state.

61.Leadville got its name for the following reasons EXCEPTC.
A.because Tabor became its leading citizen
B.because great deposits of lead is expected to be found there
C.because it could bring good fortune to Tabor

B.to open a general store
C.to do one's contribution to the development of the mine
D.to supply miners with food and supplies and in return get a share in the mine,if one was discovered
63.Tabor made his first fortuneA.
A.by supplying two prospective miners and getting in return a one-third interest in the findings

D.as a land speculator
