 _51_ You probably think you will never be a top student. This is not necessarily so, however. Anyone can become a better student if he or she wants to. Here’s how: 

 Plan your time carefully. When planning your work, you should make a list of things that you have to do. After making this list, you should make a schedule of your time. First your time for eating, sleeping, dressing, etc. Then decide a good, regular time for studying._52_ A weekly schedule may not solve all your problems, but it will force you realize what is happening to your time. 

 Find a good place to study. Look around the house for a good study area. Keep this space, which may be a desk or simply a corner of your room, free of everything but study materials. No games, radios, or television. When you sit down to study, concentrate on the subject. 

 Make good use of your time in class.  53  Listening carefully in class means less work later. Taking notes will help you remember what the teacher says. 

 Study regularly. When you get home from school, go over your notes, review the important points that your teacher is going to discuss the next day, read that material.  54 If you do these things regularly, the material will become more meaningful, and you’ll remember it longer.

    Develop a good attitude towards tests. The purpose of a test is to show what you have learned about a subject. They help you remember your new knowledge. The world won’t end if you don’t pass a test, so don’t be over worried. 

 _55_ You will probably discover them after you have tried these.

A. There are other methods that might help you with your studying.

B. Don’t forget to set aside enough time for entertainment. 

C. Take advantage of class time to listen to everything the teacher says.

D. No one can become a top student unless he or she works hard.

E. Maybe you are an average student. 

F. Make full use of class time to take notes of what the teacher says in class.

G. This will help you understand the next class.

As people slowly learn to cure diseases, control floods, prevent hunger, and stop wars, fewer people die every year. As a result, the population of the world is becoming larger. In 1925 there were about 2 billion people in the world; today there are over 6 billion.
   When the number rises, extra mouths must be fed. New lands must be brought under development, or land already farmed must be made to produce more crops. In some areas the land is so over-developed that it will be difficult to make it provide more crops. In some areas the population is so large that the land is divided into too tiny units to make improvement possible with farming methods. If a large part of this farming population went into industrial work, the land might be farmed much more productively (多产地) with modern methods.
   There is now a race for science, technology, and industry to keep the output of food rising faster than the number of people to be fed. New types of crops, which will grow well in bad weather, are being developed, so there are now farms beyond the Arctic Circle in Siberia and North America. Irrigation (灌溉) and dry-farming methods bring poor lands under the plough. Dams hold back the waters of great rivers, which can provide water for the fields in all seasons and provide electric power for new industries. Industrial chemistry provides fertilizer to suit different soils. Every year, some new methods are made to increase or to protect the food of the world.
48. The author says that the world population is increasing because _____.
 A. there are many rich valleys and large fields
 B. farmers are producing more crops than before
 C. people are living longer due to better living conditions
 D. new lands are being made into farmlands
49. The author says that in areas with large populations, land might be more productively farmed if _____.
 A. the land was divided into smaller pieces
 B. people moved into the countryside
 C. industrial methods were used in farming
 D. the units of land were much larger
50. We are told that there are now farms beyond the Arctic Circle. This has been made possible by _____.
 A. growing new types of crops
 B. irrigation and dry-farming means
 C. providing fertilizers 
 D. destroying pests and diseases

Today many people say that women have the same chance as men in society. But this was not always so. In the past, women all over the world had to fight to get the same chance as men in education and jobs. Many people said that women should not receive much education because they would not do as well as men when they went to work..
   One woman who showed that women should have the same chance was Marie, a scientist. In the 1800s scientists knew that a metal, uranium(铀), gave off radiation. They also knew how much radiation came from his element. But they didn’t know what this radiation was like; they wondered why and how uranium gave off radiation. Marie Curie set out to answer these questions. In one of her experiments she was studying a certain material which, she knew, contained uranium, But it gave off 4 times as much radiation as usually does. What could explain this fact? Marie Curie thought that there must be another source of radiation in this material.
   In 1898 Marie Curie set out to find out this new source of radiation, which she named “radium(镭)”. Her husband, who was also a scientist, helped her. They set up a laboratory in an old building behind a school. For four years Curies searched, doing many experiments, And one morning in 1902 Marie found the source of the radiation.
Marie Curie proved to the world that there was element that gave off radiation. And she also proved to the world that, if women are given truly equal chance, they can really help society.
44．The scientists of Marie Curie’s day knew         .
 A. that uranium gave off radiation              
 B. that radium gave off radiation
 C. that there was some radium in uranium

45．The Curies found the element radium         .
 A. with other scientists’ help                        B. by asking some famous scientists
 C. by doing many experiments                     D .with their teachers’ help
46．In the past many people thought         .
 A. that women must get the same chance as men in education and jobs
 B. that women should receive much education
 C. that women should get good jobs
 D. that women could not do the work well
47．Marie Curie proved to people         .
 A. that there was a new element uranium
 B. that there was a new element radium
 C. that women could do their work as well as men if they were really given the same conditions
 D. both B and C

Three blondes (金发碧眼的女人) were being trained to become detectives by a policeman. To test their skills in recognizing a suspect (嫌疑犯), the policeman showed the first blonde a picture for five seconds and then asked how she could recognize him. She thought it easy, for the suspect had only one eye. The policeman felt disappointed at this funny answer. He showed the second lady the picture for five seconds and asked her how she would recognize him. The second blonde giggled, flipped her hair, and said, "Ha! It’s easy to find the one-eared person!" Her answer also made the policeman angry. Turning to the third lady, he asked, "This is your suspect, and how would you recognize him?" He added quickly, "Think hard before giving a stupid answer." The third blonde looked at the picture carefully for a moment and said, "HMMMM ... the suspect is wearing contact lenses (隐形眼镜)." The policeman was surprised and speechless, because he really didn't know himself if the suspect wore contacts or not. "Well, that is a good answer. Wait here for a few minutes while I check his file." He left the room and went to his office, checked the suspect's file in his computer and returned with a beaming smile. "Wow! I can't believe it ... it's TRUE! The suspect does in fact wear contact lenses. Good work! How were you able to make such a wise observation?" "That's easy," the blonde replied, "he can't wear glasses because he only has one eye and one ear!"
