题型:不详难度:来源:
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(双筒望远镜) 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(抛物线的) 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.
小题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 |
A.One must know something about astronomy and telescopes. |
B.One can’t buy a telescope without buying several astronomy magazines. |

D.One must be familiar with new information of astronomy and space instruments. |
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. |
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. |

举一反三
Several states later I was still thinking about the hitchhiker.Leaving him standing in the desert did not bother me so much.What bothered me was how easily I had reached the decision.I never even lifted my foot off the accelerator.
Does anyone stop any more?I wondered.I recalled Blanche DuBois’s famous line:“I have always depended on the kindness of strangers”.Could anyone rely on the kindness of strangers these days?One way to test this would be for a person to journey from coast to coast without any money,relying solely on the good will of his fellow Americans.What kind of Americans would he find?Who would feed him,shelter him,carry him down the road?
The idea intrigued me.
The week I turned 37,I realized that I had never taken a gamble in my life.So I decided to travel from the Pacific to the Atlantic without a penny.It would be a cashless journey through the land of the almighty dollar.I would only accept offers of rides,food and a place to rest my head.My final destination would be Cape Fear in North Carolina,a symbol of all the fears I’d have to conquer during the trip.
I rose early on September 6,1994,and headed for the Golden Gate Bridge with a 50pound pack on my back and a sign displaying my destination to passing vehicles:“America”.
For six weeks I hitched 82 rides and covered 4,223 miles across 14 states.As I traveled,folks were always warning me about someplace else.In Montana they told me to watch out for the cowboys in Wyoming;in Nebraska they said people would not be as nice as in Iowa.Yet I was treated with kindness everywhere I went.I was amazed by people’s readiness to help a stranger,even when it seemed to run contrary to their own best interests.
小题1:Why did the author drive past the young man in the desert without stopping?
A.Because he failed to notice this man. |
B.Because he was driving too fast. |
C.Because he thought the young man didn’t need help. |
D.Because he was afraid of being tricked. |
A.Leaving the young man alone in the desert. |
B.Being considered a fool. |
C.Making the decision of not offering help so easily. |
D.Keeping thinking about the young man. |
A.find out how long he could survive without help |
B.go through the great difficulty in surviving unexpected environment |
C.find out whether strangers would offer help to him |
D.figure out how strangers thought of his plan |
A.describe how he fooled the strangers |
B.describe how strangers went out their way to help him |
C.explain why people refused to help strangers |
D.explain how he overcame his difficulties on the way |

Stand Straight
The first thing that you need to do is,stand straight.If you feel that you are falling backwards,then just put your chin(下巴) up and slightly bend your knees.Don’t worry;this happens to all.
Confidence Is What You Need
The most important step while learning how to skate backwards,is having enough confidence in yourself and in what you are doing.How can you achieve this?By practice.Just practice rolling backwards down a gentle slop every single day or just by pushing off from a wall or something of that sort.But before you do that,make sure that the place where you are practicing is free from any kind of debris(碎片) because otherwise,you could land up in the hospital due to some accident.While going backwards,just get used to the feeling of moving backwards.One of the important ice skating tips and techniques is that if you feel that you are losing your balance,then scissor(做剪式运动) your skates.Keep practicing this till you are confident about it.
Maintain Speed
Confident now?Great!Now the next step is to maintain your speed.While rolling in a straight line with one skate,with the other try sculling(划桨),that is,keep pushing yourself backwards with an outwards stroke(滑动).Now bring the skate which you were using to scull,and then again,repeat the same process.Make sure that you put most of your weight on the skate which is moving straight and not the one with which you are sculling.Now,try the same thing using the other foot.Again keep doing this till you are confident enough.
Increase Your Speed Now
Once you are confident that you can scull with either foot,the next thing that you have to do is increase your speed.Try some of your own tricks now.Scull with either foot or with both at the same time.
Scull and Be Aware
While you keep one foot straight,keep sculling with the other.You can do that simultaneously with both feet.Concentrate on what you are doing but don’t get so involved,that you don’t see where you are going.If you are not watching your back,you might just bang against something or someone.
小题1:According to the text confidence comes from ______.
A.high speed | B.strict coaches |
C.constant exercise | D.good techniques |
a.Increasing your speed.
b.Being able to scull with one foot.
c.Being about to stand straight.
d.Trying some different tricks.
A.c→a→d→b | B.c→b→d→a |
C.a→c→b→d | D.c→b→a→d |
A.skate in a scissor gesture |
B.use both your feet to scull |
C.skate forward first and then backward |
D.put most of your weight on the skate with which you are sculling |
A.to compare different ways of iceskating backwards |
B.to introduce the culture of iceskating backwards |
C.to explain advantages of iceskating backwards |
D.to offer some advice on iceskating backwards |
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(室内音乐的) 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(守纪律的) 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.
小题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 |
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. |
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. |
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. |
