Most of the flowers in nature are red, orange and yellow. If we have seen a black flower, it’s a chance in a million.
People have made a census (普查) to colors of mor e than four thousand kinds of flowers and discovered that only eight of them are black.
As we know, sunlight is formed by seven different colored lights.The wave length of each light is different, so the quantity of heat in each light is also different. Flowers, especially their petals, are easy to be harmed by light temperature.
Black flowers can take in all the light waves which cause the flowers to dry up in the high temperature. So black flowers can rarely survive sunlight. But red flowers, yellow flowers and orange flowers can protect themselves from sunlight by reflecting the red light, yellow light and orange light, each of which has a large quantity of heat.
1. It is _____ to see a black flower.
A. impossible     B. seldom          C. common       D. no chance
2. From the passage we know that _______.
A. black flowers are so weak that it is difficult for them to grow up.
B. there are only eight black flowers in nature
C. sunlight is formed by seven different colored lights, so the wave length of each light is different
D. black flowers can take in the light of all the wave length which makes them dry up because of high temperature
3. Which of the following ideas is WRONG?
A. People have found that only a few kinds of flowers are black.
B. Flowers are easy to be harmed by very high temperature.
C. Red, orange and yellow flowers can also take in the light of all wave lengths.
D. The black flowers can’t protect themselves from sunlight.

C

       The words “timetable” and  “schedule” make most final year students want to eat their own vomit(呕吐物). Unfortunately, the harsh reality is that final year students must develop a timetable. If you don’t have a schedule or plan for studying ,you will have no way of allocating your valuable time when the unexpected arises. A well-thought-out timetable can be a lifesaver . It is up to you to learn how to develop a schedule that meets your needs .Change it if necessary ,but most important ,follow it . All timetables should be made with the idea that they can be changed. A good one will keep you from wandering off course.
A good timetable should make every hour count—every class ,social event and other activity you engage in .You must focus on the other “free time” available and how you will use it .Make a weekly schedule and divided each day into one-hour increments .Indicate times for classes ,socializing ,and work time. Also block off a period for sleeping every day. In the precious hours left over ,plan time for study .This gives you a rough road map of the time available. Of course ,you can change your schedule as circumstances need.
The timetable you develop should guide you in how to distribute the available time in the most productive manner .Sticking to your schedule can be tough ,but don’t dribble away valuable time. Avoiding study is the easiest thing in the world .It is up to you to follow the schedule you’ve prepared .A good deal of your success in high school and with any future study depends on this simple truth.
Remember ,there is a learning curve. You learn the most in the first 30 minutes of study; after that ,it progressively deteriorates(减弱). After four or five hours of studying the same material in the same way, you are learning virtually nothing. The solution is to keep switching subjects and study styles.
64.What is the best title of the passage?
A.Advantages of starting a timetable         B.Keep to it ,and you will succeed
C.Make a schedule ,and follow it             D.Learn to love your timetable
65.What does Paragraph 2 talk about?
A.Tips for making a schedule.                  B.Significance of a scientific timetable.
C.Requirements for making a timetable.    D.Importance of following one’s schedule.
66.The following are characteristics of a good timetable EXCEPT that    .
A.it can be changed                                 B.it is flexible
C.it is of many periods                            D.it can save our time
67.From this passage ,we can learn if we wish to achieve high learning efficiency, we’d better    .
A.shift subjects and use different methods regularly
B.devote to the same material continuously
C.turn to teachers for help if necessary
D.have a break every thirty minutes

The purpose of a letter of application(求职信) is to help you to “sell” yourself. It should state__16___ the job you want, and should tell what your abilities are and what you have ___17___. It should be simple, human, personal and brief without ___18___ out any necessary facts.
In writing a letter of application, keep in ___19___ that the things a possible employer is most ___20___ to want to know about are your qualifications(条件), your achievements and your aims.

Try to ___28___ generalities. Be clear about the kind of job for which you are now ___29___. College graduates looking for their first positions often ask “What can I ___30___ in a letter? Employers want experience—which, naturally, no ___31___ has.” The answer is that everything you have ever done is ___32___.
It is important to write a good strong closing for your letter. ___33___ a specific request for an interview or give the possible employer something definite to do or expect.

The desire to make explorations is born with man. Wherever his imagination goes, man also has a strong wish to go. A large part of human history is connected with the exploration of the world in which we live. Again and again people have set out with surprising courage and patience to look into unknown regions and lands to see what had not yet been seen, to make known the unknown. With kites, balloons and aircraft they left the ground to pass through the lower atmosphere. Now the outer space receives their attention.
Why should man take the trouble of exploring space? It is hard to list the specific practical benefits that will result in. But one knows, from past experience in other areas, that man will surely see and discover new things in space that will increase our scientific knowledge, and this new knowledge will find its way into valuable practical uses. What we learn about man himself, from his experience in space, and from the effects of space and the space flight environment on him, will be extremely valuable. The new techniques developed to carry out the exploration of space, and to keep man alive in space, will certainly find practical uses in everyday life in some way. The areas that will benefit are manifold. They include communication, generation of power, transportation and travel, food production, materials, fuels and many others. But to say exactly what the practical results will be is almost impossible.
1. The main idea of the first paragraph is that __________.
A. man often goes wherever his dreams go
B. man desires to explore what is unknown
C. man is no longer interested in the study of the land and sea now
D. man's history is his exploration of the world
2. The word "manifold" in the second paragraph probably means ________ .
A. of value       B. of use       C. in a way      D. in many ways
3. The author seems to be in favor of ____.
A. the exploration of space
B. doubting the necessity of the space exploration
C. exploring more in space than in sea         
D. his experience in space
4. In the last sentence of paragraph 2 ,the phrase "practical results" refers to the results ______.
A. that can be made use of
B. that can be learned as knowledge
C. that are obtained from experience         
D. helping us make further exploration
