If you are ever planning to buy a telescope and want to get yourself involved in astronomy it is always a good idea to know a bit of the sky.Get acquainted with a few constellations(星座) so that it will be easier for you to spot the constellations when you are using your telescope.
It’s a good idea to buy a few magazines on astronomy to help you to get familiar with the constellations in the sky and also read a few reviews on the different types of telescopes in the market.This will help you gather all the information that is out there regarding telescopes and what people have to say about them.
It’s advisable to go in for a pair of binoculars(雙筒望遠鏡) before you buy your first telescope so that you can get used to spotting constellations before your view of the sky is narrowed down.This will also help you know if you really want to get involved in astronomy.Many people buy a costly telescope and then discover that they’re not actually interested in astronomy.
Experience has no substitute,and there certainly is nothing better than using different telescopes before you buy one.This will help you to get the feel of all the types of telescopes and you will know which one is easier for you to use.A large aperture(光圈) refractor(折射) may give you an excellent image but you may not be able to keep a steady hand while using it resulting in a blurry image.
There are three types of telescopes that are available in the market.If you want a more elegant looking telescope you can always choose to buy a fine brass telescope.It’s good to become acquainted with each type before going for the plunge of a first telescope.The first type of telescope is the refractor telescope,which uses lenses to gather light to a focus at the eye piece.The use of lenses helps the telescope have a superior image.A refracting telescope is not as portable as the other two types of telescopes and so you will have to buy one with a small aperture.
The second type of telescope is the Reflector.Made by Sir Isaac Newton,this telescope functions by focusing the light back at the front of the tube,which is where the eyepiece sits,by using parabolic(拋物線的) mirrors and another smaller mirror to deflect the light.There is no added color in the image caused by refraction of light since this telescope does not use lenses.These are the cheapest of all telescopes and are more portable than refractors.
小題1:According to the text,a telescope is intended to be bought for ________.
A.getting experience
B.watching stars
C.studying the climate
D.learning about a bit of the sky
小題2:What can we learn from Paragraph 2?
A.One must know something about astronomy and telescopes.
B.One can’t buy a telescope without buying several astronomy magazines.
C.One should check the telescopes in the market and try to find a better one.
D.One must be familiar with new information of astronomy and space instruments.
小題3:Why does the author advise buying a pair of binoculars first?
A.The telescope is too expensive.
B.The binoculars are easier to use.
C.You may gain plenty of experience in astronomy.
D.Your view will be narrow by using a pair of binoculars.
小題4:What do we know about the refracting telescope?
A.It looks very elegant.
B.It refracts light by an eye piece.
C.It has clear images without any lenses.
D.It is not convenient to take along for its size.

小題1:B
小題2:A
小題3:C
小題4:D

小題1: B
解析 推理判斷題。在第一段中作者建議買望遠鏡之前多了解一些天文知識,特別是星座方面的知識,這就說明望遠鏡的用途是用來觀察星星。
小題2: A
解析 段落大意題。作者建議在購買望遠鏡前多了解一些天文知識,并且了解人們對市場上各種望遠鏡的評價,從而對產(chǎn)品有所了解。
小題3:C
解析 細節(jié)理解題。在第三段,作者建議先使用雙筒望遠鏡以獲取經(jīng)驗并且確定對觀測天文現(xiàn)象是否真的感興趣。
小題4: D
解析 細節(jié)理解題。根據(jù)倒數(shù)第二段“A refracting telescope is not as portable as the other two types...”可知,折射望遠鏡不如其他兩種方便攜帶。

Jack Benny was one of the most famous names in show business.He was born in Chicago,Illinois,on February 14th,1894.His parents,Meyer and Emma Kubelsky,were religious Jews.They had moved to the United States from Eastern Europe.Benny was a quiet boy.For much of the time,his parents were busy working in his father’s store.As a child,Benny learned to play the violin.After finishing his school,he joined the Navy.He continued using his violin to perform for sailors.In one show he was chosen more for his funny jokes than for his skill with the violin.That experience made him believe that his future job was a comedian.

Benny received many awards during his lifetime.Perhaps the one honour that pleased him most was that his hometown of Waukeegan named a school for him.This was a special honour for a man who had never finished high school.
Benny continued to perform.He died of cancer in 1974.At his funeral his friend Bob Hope said,“Jack Benny was stingy to the end.He gave us only eighty years.”

When I was 12,all I wanted was a signet(圖章) ring.They were the “in” thing and it seemed every girl except me had one.On my 13th birthday,my Mum gave me a signet ring with my initials(姓名首字母) carved into it.I was in heaven.
What made it even more special was that it was about the only thing that wasn’t being “replaced”.We’d been burnt out in fires that swept through our area earlier that year and had lost everything—so most of the “new” stuff(東西) we got was really just to replace what we’d lost.But not my ring.My ring was new.
Then,only one month later,I lost it.I took it off before bed and it was missing in the morning.I was sad and searched everywhere for it.But it seemed to have disappeared.Eventually,I gave up and stopped looking for it.And two years later,we sold the house and moved away.
Years passed,and a couple of moves later,I was visiting my parents’ when Mum told me that she had something for me.It wasn’t my birthday,nor was it Easter or Christmas or any other gift­giving occasion.Mum noticed my questioning look.“You’ll recognize this one,” she said,smiling.
Then she handed me a small ring box.I took it from her and opened it to find my beautiful signet ring inside.
The family who had bought our house 13 years earlier had recently decided to do some redecorations,which included replacing the carpets.When they pulled the carpet up in my old bedroom,they found the ring.As it had my initials carved into it,they realized who owned the ring.They’d had it professionally cleaned up by a jeweler before sending it to my mother.
And it still fits me.                       (2013·福建,A)
小題1:The underlined word “in” in the first paragraph probably means “________”.

How to deal successfully with a child who shows outstanding musical ability?It’s not always clear how best to develop and encourage his gift.Many parents may even fail to recognise and respond to their children’s need until frustration explodes into difficult or uncooperative(不合作的) behaviour.And while most schools are equipped to deal with children who are specially able in academic subjects,the musically gifted require special understanding which may not always be available in an ordinary school—especially one where music is regarded as a secondary activity.Such children may well benefit from the education offered by a specialist music school.
The five music schools in Britain are a relatively recent introduction.They aim to provide an environment in which gifted children aged between seven and eighteen can develop their skills to the full under the guidance of professional musicians.
Children at specialist music schools spend between one third and one half of an average day on musical activities,for example,individual lessons,orchestras,chamber(室內(nèi)音樂的) groups,voice training,conducting and theory.They also spend several hours a day practising in properly equipped private rooms,sometimes with a teacher.The rest of their time is taken up with the subjects:English,maths,basic sciences and languages.All five British specialist schools are independent,classes are small by normal school standards,with a high teacher/pupil ratio(比率).Most children attending specialist schools tend to be boarders,leaving home to live,eat and sleep full­time at school.
What are the disadvantages?An obvious problem is the cost;the fees are high(£12,000­£17,000 a year for boarders).However,each school will make every effort with scholarships and other forms of financial assistance,to help parents of outstandingly gifted children to find the necessary fees.Secondly,not all parents want to send their children to boarding school,especially at a very early age.Almost all the directors of the specialist schools express doubts about the wisdom of admitting children as young as seven into such an intense and disciplined(守紀律的) environment.They stress,however,that their main aim is to turn out “rounded and well­balanced” individuals.
There is little doubt that setting musically gifted children apart from an early age can cause stress.Early signs of musical ability may disappear in their teenage years,while natural competitiveness and the pressure to succeed can lead to a deep sense of failure.But all specialist schools do keep a close watch on the progress of individual pupils,and offer help and advice if needed.
小題1:If a child’s musical ability is not recognized,________.
A.the child may misbehave
B.the ability may fade away
C.the child may lose interest
D.the parents may become anxious
小題2:What problem may musically gifted children face in ordinary schools?
A.Their academic work may suffer.
B.Schools lack musical equipment.
C.Music is not seen as an important subject.
D.Parents and teachers do not work together.
小題3:What makes specialist music schools different from other schools?
A.Their working day is longer.
B.A range of musical training is offered.
C.More than half the day is spent on music.
D.The children have mostly one­to­one lessons.
小題4:What do most school directors see as a possible disadvantage for pupils?
A.Poor children may not be included.
B.They may lose their individuality.
C.There may be a discipline problem.
D.They may not be mature enough on arrival.

With the average temperature for January standing at -50 ℃,it is no wonder the Russian village of Oymyakon is the coldest permanently inhabited settlement in the world.Known as the“Pole of Cold”,the coldest ever temperature recorded in Oymyakon is -71.2 ℃.This is the lowest recorded temperature for any permanently inhabited location on Earth and the lowest temperature recorded in the northern hemisphere(北半球).
Ironically,Oymyakon actually means“non?freezing water”due to a nearby hot spring.Most homes in Oymyakon still burn coal and wood for heat and enjoy few modern conveniences.
Nothing grows there so people eat reindeer(馴鹿)meat and horsemeat.A single shop provides the town's bare necessities and the locals work as reindeer?breeders,hunters and ice?fishermen.
There are few modern conveniences in the village—with many buildings still having outdoor toilets—and most people still burn coal and wood for heat.When coal deliveries are irregular,the power station starts burning wood.If the power ceases,the town shuts down in about five hours,and the pipes freeze and crack.
Daily problems that come with living in Oymyakon include pen ink freezing,glasses freezing to people's faces and batteries losing power.Locals are said to leave their cars running all day for fear of not being able to restart them.Even if there was coverage for mobile phone reception,the phones themselves would not work in such conditions.
Another problem caused by the frozen temperatures is burying dead bodies,which can take anything up to three days.The earth must first have thawed(融解)sufficiently in order to dig it,so a bonfire is lit for a couple of hours.Hot coals are then pushed to the side and a hole couple of inches deep is dug.The process is repeated for several days until the hole is deep enough to bury the coffin.
Travel companies offer tourists the opportunity to visit the village and sample life in the freezing conditions.
小題1:From the passage we can infer that people in Oymyakon ________.
A.prefer meat to any other kind of food
B.seldom have fresh vegetables and fruits
C.can buy anything in the shop
D.might row a boat to catch fish
小題2:Which of the following is the first step when burying a dead body?
A.The coffin must be put in place.
B.A bonfire has to be lit first.
C.Hot coals have to be pushed to the side.
D.A hole couple of inches deep is dug.
小題3:Mobile phones would not work in Oymyakon because ________.
A.the batteries are of poor quality
B.there was no coverage for phone reception
C.batteries can't be charged in such conditions
D.the extreme coldness makes the batteries lose power
小題4:Why do the locals have their cars running all day?
A.They are afraid they can't get the car started.
B.They want to keep warm in the car.
C.They have abundant oil resources.
D.They have little awareness of saving.

For most people, shopping is still a matter of wandering down the street or loading a cart in a shopping mall. Soon, that will change. Electronic commerce (trade) is growing fast and will soon bring people more choices. There will, however, be a cost: protecting the consumer from being cheated will be harder. Many governments therefore want to apply street regulations to the electronic world. But politicians would be wiser to see cyberspace as a basis for a new era of corporate self-regulation.
Consumers in rich countries have grown used to the idea that the government takes responsibility for everything from the stability of the banks to the safety of the drugs or their rights to refund when goods are faulty. But governments cannot enforce national laws on businesses whose only presence is on the screen. Even in a country where a clear right to compensation exists, the on-line customer in Tokyo, say, can hardly go to New York to get a refund (退款) for a clothes purchase.
One answer is for government to cooperate more: to recognize each other’s rules. But that requires years of work and volumes of detailed rules. And plenty of countries have rules too fanciful for sober countries to accept. There is, however, another choice. Let the electronic businesses do the regulation themselves. They do, after all, have a self-interest in doing so.
In electronic commerce, a reputation for honest dealing will be a valuable competitive asset. Governments, too, may compete to be trusted. For instance, customers ordering medicines on- line may prefer to buy from the United States because they trust the rigorous screening of the Food and Drug Administration; or they may decide that the FDA’s rules are too strict, and buy from Switzerland instead.
Customers will still need to use their judgment, but precisely because the technology is new, electronic shoppers are likely for a while to be a lot more cautious than customers of the normal sort. And the new technology will also make it easier for them to complain when a company lets them down. In this way, at least, the advent(出現(xiàn)) of cyberspace may argue for fewer consumer protection laws, not more.
小題1:In case an electronic shopper bought faulty goods from a foreign country, what could he do?
A.Refuse to pay for the purchase.B.Go to the seller and ask for a refund.
C.Appeal to consumer protection law.D.Complain about it on the Internet.
小題2:In the author’s view, businesses would place a high emphasis on honest dealing because in the electronic world _______.
A.international cooperation would be much more frequent
B.consumers could easily seek government protection
C.a(chǎn) good reputation is a great advantage in competition
D.it would be easy for consumers to complain
小題3:We can infer from the passage that in licensing new drugs the FDA in the United States is______.
A.very quickB.very cautiousC.very slowD.rather careless
小題4:According to the author, what will be the best policy for electronic commerce?
A.Self-regulation by the business.B.Strict Consumer protection laws.
C.Close international cooperation.D.Government protection.
