If you dream of going someplace warm to escape the cold winter weather,a trip to a recently discovered planet would certainly warm you right up.The planet,named
OGLE-TR-56b,has temperatures of more than 3,000°F.“This is the hottest planet we know about,”says Dr Dimitar Sasselov,a scientist who led the discovery team.“It is hot enough to have an iron fog and to rain hot iron droplets(细沫).”
The new planet is 30 times farther away than any planet discovered by scientists
before.It is in the Milky Way(银河)but it is not in our solar(太阳的)system.The new planet moves around a star much like our sun,however scientists discovered the planet by using a new planetsearching method called transit technique.They were able to catch sight of the planet when it moved in front of its star,causing the star"s light to dim(变暗).Scientists compare the method to discovering the shadow of a bee flying in front of a searchlight 200 miles away.“We believe the door has been opened wide to go and discover planets like the Earth,”says Sasselov.
1.We can infer from the passage that_________.
A.there is iron on the new planet
B.we could go to the new planet in winter
C.the star could block our view of the new planet
D.scientists are studying the weather
2.The “transit technique”can_____________.
A.help dim the light of a star
B.help scientists with a searchlight
C.help discover a bee on a planet
D.help find a planet moving before its star
3.Which is the best title for the passage?
A.New Planet searching Technique
B.New Distant Discovery
C.Space Searching
D.Dream Planet

答案

1----3 CDB

解析

1.此题考查考生进行推理判断的能力。文中第一段最后作者提到的iron fog只是一种比喻，来表明这颗行星温度之高，并不能由此推断它的上面有铁。A是不成立的。文中第一句话：如你梦想着去一个温暖的地方以躲避寒冷的冬季，那么到新近发现的一个行星上去会让你立刻暖和起来。这句话是为了引起下文，不能作为推断的依据，因此，B选项错误。D选项说科学家们正在研究这颗新星上的天气情况，文中没有提及。文中第二段：科学家们用一种叫做transit technique的新方法发现了这颗新星。这颗星围绕一颗类似太阳的恒星运转。当它转到这颗恒星前面时，使得恒星的光变暗，这时他们就能看见它了。C选项：这颗恒星会阻挡我们的视线，使我们看不到新星。这个推断是正确的。答案为C。
2.其中的D选项与上题观点一致，也就是用来发现新星。答案为D。
3.这道题考查考生概括文章主旨大意的能力。对于这类题，最好的方法就是用假设的方法去判断。因为标题应该在最大程度上覆盖全文。此篇文章主要围绕这颗新星的发现展开。答案为B。

举一反三

There are three separate sources of danger in supplying energy by nuclear power(原子能).
First, the radioactive material must travel from its place of production to the power station. Although the power stations themselves are strongly built, the containers used for the transport of the materials are not. Normally, only two methods of transport are in use, namely road or rail. Unfortunately, both of these may have an effect on the general public, since they are sure to pass near, or even through, heavily populated areas.
Second, there is the problem of waste. All nuclear power stations produce wastes that in most cases will remain radioactive for thousands of years. It is impossible to make these wastes nonradioactive, and so they must be stored in one of the inconvenient ways that scientists have invented. For example, they may be buried under the ground, or dropped into deserted mines, or sunk in the sea. However, these methods do not solve the problem, since an earthquake could easily break the containers.
Third, there may occur the danger of a leak(泄漏) or an explosion at the power station. As with the other two dangers, this is not very likely, so it does not provide a serious objection to the nuclear program. However, it can happen.Separately, these three types of dangers are not a great cause for worry. Taken together, though, the probability of disaster(灾难) is extremely high.
1.Which of the following is FALSE?
A.It is possible that a leak or an explosion occurs at a power station.
B.It is unusual for radioactive materials to be transported across land.
C.The containers are likely to be broken by an earthquake.
D.Nuclear wastes remain dangerous in most cases for many years.
2.The author thinks that the ways to store nuclear wastes are ________.
A.easy B.impossible C.reasonable D.ineffective
3.What do we learn from the last paragraph?
A.The power station is a safe place.
B.The dangers of nuclear energy can be prevented.
C.The general public are strongly against the nuclear program.
By itself, none of the three dangers is very likely to cause much worry.
4.What is this passage about?
A.Uses of nuclear power. B.Dangers from nuclear power.
C.Public anger at nuclear power. D.Accidents caused by nuclear power.

If there is no difference in general intelligence(智力)between boys and girls,what can explain girls" poor performance in science and mathematics?
It seems to be that their treatment at school is a direct cause.Mathematics and science are seen as subjects mainly for boys,and therefore ,as girls become tee
nagers,they are less likely to take them.Interestingly,both boys and girls often
regard the subjects for boys as more difficult.Yet it has been suggested that girls do not take mathematics courses ,not because they are difficult,but for social reasons.Girls do not want to be in open competition with boys because they are afraid to appear less feminine(女性的)and attractive.
However,if we examine the performance of boys and girls who have taken mathematics courses,there are still more highachieving boys than there are girls.This difference appears to be worldwide.Biological explanations have been offered for this,but there are other explanations too.
Perhaps the difference which comes out during the teenage years has its roots in much earlier experiences.From their first days in kindergarten,boys are encouraged to work on their own and to complete tasks.Facts show that outstanding(杰出的)mathematicians and scientists have not had teachers who supplied answers.
Besides,there can be little doubt that teachers of mathematics and science expect their boy students to do better at these subjects than their girl students.They even appear to encourage the difference between boys and girls.They spend more time with the boy students ,giving them more time to answer questions and working harder to get correct answers from them.They are more likely to call on boys for answers and to allow them to take the lead in classroom discussion.They also praise boys more frequently.All of this seems to encourage boys to work harder in science and mathematics and to give them confidence(信心)that they are able to succeed.
Such a way of teaching is not likely to encourage girls to take many mathematics
and science courses,nor is it likely to support girls who do.When it comes to these subjects it seems certain that school widens the difference between boys and girls.
1.Girls are likely to think that____________.
A.science courses are for both boys and girls
B.science courses make them more popular
C.science courses make them successful
D.science courses are difficult for them
2.The text mainly discusses_____________reasons for the difference between boys and girls in scientific achievements.
A.biological         B.historical          C.social       D.personal
3.What are boys usually encouraged to do at school?
A.To get help with their homework.
B.To play the leading role in class.
C.To work with girl students in class.
D.To learn to take care of others.
4.What does the passage say about great mathematicians?
A.Their teachers did not supply answers to them.
B.They started learning mathematics at an earlier age.
C.They showed mathematical abilities in their teenage years.
D.Their success resulted from their strong interest in mathematics.
5.The author would probably agree that_____________.
A.boys and girls learn in the same way
B.boys and girls are equal in general intelligence
C.girls are more confident in themselves than before
D.girls should take fewer science courses than boys

Have you ever got stuck with unwanted courses or a class schedule that cannot be changed? If so, that"s because you don"t know how to select the perfect sch
edule. But by following a few simple steps, you can begin any term with the right courses at the most convenient times.
First, you must find the right courses. These are the ones that have the least amount of work, the fewest tests and the kindest professors. Ask your friends about courses in which they received A"s after attending only 70 percent of the classes. Ask around, too, to see which instructors have given the same tests for the last fifteen years. Photocopies of these tests are usually cheap and can be easily found in school. Then, pick up a copy of the master schedule and study it carefully. Find the course titles that mean an easy pass for a painless subject.
Look for titles like “Arts and Crafts for Beginners” and “Rock Music of the 1950s”.
Next, when you have got lists of easy instructors and subjects, you can begin to select your time periods. If you stay up late in order to watch old movies, you may want a daily schedule that begins no sooner than noon. You should schedule only afternoon courses, too, if you"re one of those people who hate to leave a warm bed in the morning. On the other hand, if you are a person who gets out of bed at dawn, you may want to get your classes out of the way as early as possible. That way you have the rest of the day free. Morning classes are also necessary if you are a soap opera(肥皂剧) fan.
Finally, you want your schedule to pass through registration successfully. The main way to do this is to register(注册) early. If a course does happen to be closed because you simply couldn"t register at 7:00 am, you may still be able to get in. Talk to the professor and tell him or her that a serious and hardworking student like yourself would be a shining example to other students. Be sure to carry a list of back-up courses to registration, though, just in case one of your chosen classes changes professors or time periods.
By following these suggestions, any student can pick the perfect class schedule. College can thus become an almost pleasant activity.
1.Which of the following statements is true?
A.You can get copies of tests if you are willing to pay the price.
B.“Rock Music of the 1950s” may be an easy course.
C.It is difficult to pick the perfect class schedule.
D.Attendance is required in all classes.
2.You should ________ .
A.register for classes in the morning if you get up early
B.have classes late in the morning if you stay up late
C.sign up for afternoon classes if you want to see soap operas
D.choose classes in the evening if you want to watch old films
3.If a course happens to be closed, you should ________ .
A.register at 7:00 am               B.sit in on the class anyway
C.register for a back up course      D.get help from the professor
4.Which of the following would be the best title for the passage?
A.Course Registration Made Easy         B.How to Find the Right Courses
C.Classes and Afterclass Activities     D.How to Pick the Perfect Schedule

About one million years ago,the Ice Age began.The Ice Age was a long period of time in which four great glaciers(冰川) pushed southward to cover almost all the upper half of North America,and then melted away.Each glacier was a thick sheet of ice and snow that spread out from a center near what is now Hudson Bay in Canada.The winters were long,and the cool summers were too short to melt much of the ice and snow.The evergrowing sheet built up to a thickness of two miles at its center.
As all glaciers do,these great glaciers slid(滑动). They pushed down giant trees in their paths and scraped(刮削)the earth bare(光秃秃)of soil.Many animals moved farther south to escape.Others stayed and were destroyed.
When winters of little snow came,the summer suns into the edges to the ice sheets.As the glaciers melted,rocks,soil and other things that had mixed with the ice and snow were left.New hills,lakes and rivers were formed.
The last of the great glaciers began its melting about 11 000 years ago.Itsmelting formed the Great Lakes.These lakes are today little changed from their early sizes the glaciers.This is the Mississippi Missouri Ohio system.These rivers were miles wide at first.Through the years they settle into their present channels.
