per day survive in a desert environment?
In the southwest African country of Namibia, and the Sahara lands of Mali further north, the desert elephant
does just that.
Although not regarded as a separate species from the African elephant, the desert cousin differs in many
ways. Their bodies are smaller, to absorb less heat, and their feet are larger for easier walking across sandy
surfaces. They are taller to reach higher branches. They have shorter tusks, and most importantly, longer
trunks to dig for water in riverbeds.
Desert elephants can travel over 70 kilometers in search for feeding grounds and water holes, and have a
larger group of families. They drink only 3-4 days, and can store water in a "bag" at the back of their throat,
which is only used when badly needed. Desert elephants are careful feeders-they seldom root up trees and
break fewer branches, and thus maintain what little food sources are available. Young elephants may even eat
the dung (粪便) of the female leader of a group when facing food shortage.
During drought they are unlikely to give birth to their young but with good rains the birthrate will increase
greatly. Desert elephants have sand baths, sometimes adding their own urine (尿) to make them muddy!
As we continue to overheat our weak planet, it can only be hoped that other animal species will adapt (调
整适应) as extraordinarily well to change as the desert elephant.
B. drinks 120 liters of water a day
C. managed to live in desert areas
D. eats 150 kilograms of food daily
B. drink only every 3-4 days
C. search for food in large group
D. protect food sources for their young
B. facts and descriptions
C. examples and conclusion
D. evidence and arguments
B. Not all animal species are so adaptable
C. The planet will become hotter and hotter
D. Not all animals are as smart as desert elephants

| There are varieties of bee in the world. Scientists are interested in honeybees because of the "language" they use to communicate with each other. Karl von Frisch, a professor from Austria, devoted many years of his life to researching the ways honey-bees communicate in their hives (蜂房). Karl von Frisch built special hives, a glass wall and painted some honey-bees with different colors. A marked bee which returned to the hive from the feeding table performed a dance on the surface of the honeycomb (蜂巢). First it made a circle to the right, then to the left. It repeated these circles again and again. The surrounding bees copied its dances and then they left for the feeding place. Karl von Frisch set up two feeding places. One was close to the hive the other was farther away. The bees that had been at the nearby feeding place were doing the circling dance. The bees at the distant feeding place were dancing differently. The dancer ran in a straight line, wagging (摇摆) from side to side. Then it turned in a semicircle (半圆), ran straight again, and turned in another semicircle to the opposite side. It repeated the dance over and over. The dances convey messages about the far-away feeding place. Karl von Frisch and his assistants slowly moved a feeding place close to the hive farther and farther away and they counted how many times the bees repeated the dance in one minute. Finally they found out the number of wagging dances per minute told the exact distance to the feeding place. |
| 1. Scientists are interested in honeybees just because _____. |
| [ ] |
| A. The honey-bees have bright colors. B. The honey-bees enjoy a strange way of communication. C. The honeydew is delicious. D. there are several kinds of bees in the world. |
| 2. Professor Karl von Frisch was from _____. |
| [ ] |
| A. America B. Australia C. Sweden D. Austria |
| 3. What information does the dance convey? |
| [ ] |
| A. There is no feeding place around. B. The feeding place is farther away. C. The feeding place is too far for the bees to get to. D. The feeding place is near the hive. |
| 4. What did Karl von Frisch want to find out while moving a feeding place close to the hive farther and farther away? |
| [ ] |
| A. How the bees continued their dances. B. How the bees communicated the distance to the feeding place. C. The differences between the circling dance and the wagging dance. D. How the bees flew to the feeding place. |

| Maybe you are an average student. You probably think you will never be a top student. This is not necessary so, however. Anyone can become a better student if he or she wants to. Here"s how: 1. Plan your time carefully. When you plan your week, 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. Don"t forget to set aside enough time for entertainment. A weekly schedule may not solve all your problems, but it will force you to realize what is happening to your time. 2. 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. 3. Make good use of your time in class. Take advantage of class time to listen to everything the teachers say. Really listening in class means less work later. Taking notes will help you remember what the teacher says. 4. Study regularly. When you get home from school, go over your notes. Review the important points that your teacher mentioned in class. If you know what your teacher is going to discuss the next day, read that material will become more meaningful, and you will remember it longer. 5. Develop a good attitude about 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 overly worried. There are other methods that might help you with your studying. You will probably discover many others after you have tried these. |

| One end of the lamp wick (灯芯) is immersed (把......浸入......之中) in oil and the other end is not immersed. When you light the end which is not immersed, it will burst into flame. This is because the oil is able to rise up the lamp wick thus helping it to burn. In the same way, if you immerse the end of a piece of chalk into a glass of water, the water will soon climb up the chalk making it wet. If a piece of ordinary glass tubing is heated in a gas flame until it becomes soft, it can be pull into a tube of a very small hole. Immerse the tube into water or any other liquid which wets glass, you will find that the liquid rises to a height of several centimeters. This is known as capillary action. The liquid rises because there is an attractive force between the liquid and the glass. The attractive force depends on the diameter of the tube and the type of liquid used. |
| 1. Why can an oil lamp work? |
| [ ] |
| A. Because there is oil. B. Because there is oil climbing up the wick. C. Because the other end is immersed. D. Because the wet end is lighted. |
| 2. The passage mentions all the things except _____. |
| [ ] |
| A. oil B. water C. chalk D. paper |
| 3. The last sentence means that _____. |
| [ ] |
| A. the thinner the diameter, the greater the attractive force B. the diameter of the tube and the kind of the liquid decide the greatness of the force C. the thinner the diameter, the smaller the attractive force D. oil climbs up higher than water |
| 4. The liquid rises up a tube because _____. |
| [ ] |
| A. the tube is thin B. the glass has an attractive force C. the liquid tends to rise up D. both glass and liquid act on each other |
| 5. The passage mainly talks about _____. |
| [ ] |
| A. an oil lamp B. an ordinary tubing C. liquid climbing up things D. capillary action |

| If you are planning to study in the United States, you need to consider several factors. Everyone has different opinions about where is the best place to live in. Also, the best places to live are not always home to the best schools. Finally, many schools specialize in different areas of study. The Massachusetts Institute of Technology, for example, is a great school for computer science and technology-related fields of study. However, if you want to study oceanography (海洋学), your interests may be better served by attending school in a place that is on a coastline or near the ocean. Now I am sure that you know which schools are considered the best in the country. So I will tell you about which states I believe are the best to live in. California is a nice state. Northern California specifically has very good weather. Los Angeles in Southern California is another story though. Life in Los Angeles is full of excitement and fast,and sometimes dangerous. As for me, I enjoy the time I spent in Massachusetts, Virginia and Maryland and these states have a lot of history and culture. The weather is not as perfect as California, but it is still quite nice. My favorite area of America is the Mid-west. Middle America, I think, is home to the true American sense of values. In addition, there are many good universities there. Also, you need to think about your likes and dislikes and then research the various states. You like sunshine and hate snow? Then you probably won"t like the Midwest or even the Northeast. Open space, nature and peace and quiet? Then you probably should stay away from America"s large cities. Are you interested in government? Then Washington D.C. is the only place for you. Whatever you decide, put some thought into it. The place you live could be the difference between a great study-abroad experience and a state of great suffering on earth. |
