As a child, I was really afraid of the dark and of getting lost. These fears were very real and caused me some uncomfortable moments.
Maybe it was the strange way things looked and sounded in my own room at night that scared me so much. There was never complete darkness, but always a streetlight or passing car lights, which made clothes on the back of a chair take on the shape of a wild animal. Out of the corner of my eye, I saw the curtains seem to move when there was no wind. A very low sound in the floor would seem a hundred times louder than in the day. My imagination (想象) would run wild, and my heart would beat fast. I would lie very still so that the “enemy” would not discover me.
Another of my childhood fears was that I would get lost, especially on the way home from school. Every morning I got on the school bus right near my home. That was no problem. After school, though, when all the buses were lined up along the street, I was afraid that I would get in the wrong one and be taken to some other strange places. On school or family trips to a park or a museum, I wouldn’t let the leaders out of my sight.
Perhaps one of the worst fears of all I had as a child was that of not being liked or accepted by others. Being popular was so important to me then, and the fear of not being liked was a serious one.
One of the processes growing up is being able to realize and overcome our fears. Understanding the things that scared us as children helps us achieve greater success later in life.The author had _______ kind(s) of fears when she was a child.

Gasoline (汽油) prices are getting higher and higher. The prices make it hard for drivers to afford the fuel.
One group held a special event to display（展示）new kinds of cars .
The new cars are different and they can run on many different kinds of fuels . 
Some of these cars are called hybrids(混合动力). They can run on different kinds of fuels . One kind of them runs on a special fuel cell which is filled with a gas called hydrogen(氢气). ______ They are very clean , and don’t give off bad fumes(烟雾) when they run .
The man who makes fuel cell cars is excited about the technology .__ ___ Once we use oil up , it will take millions of years for more oil to form. Since gasoline is made from oil , that could be a problem for companies that make traditional cars , and for drives . __
__
Buses that run on hydrogen fuel cell power are being tested on the road . They could become a common form of transportation in the near future
| A. The fuel cell cars are also better in another way . B. However, it won’t be a problem for cars that run on fuel cells .. C. He says we will never run out the fuel, but we may run out of oil. |

It may seem easy to say that plants and animals are different. Any child can tell the difference between a tree and a dog. But those differences are far deeper than just what they look like. The cells (细胞) that plants are made up of are different. In other words, the cell wall of plants has something special. 
First of all, it's important to find that not all plant cells have a cell wall. Besides, there are many differences of a cell wall based on the kinds of plant. The following is meant to be what a plant cell wall is like.
The cell wall of a plant is on the outside of the cell membrane (膜). It is usually hard and cannot be bent easily, but the degree of flexibility (韧性) of the cell wall is different. It is based on the special use that the cell has in keeping the plant alive. Cells that make up the trunk of a tree are clearly less flexible than cells on a leaf.
Cell walls act in many ways. They serve to protect the plant. They provide support, as well as help in the movement of chemicals and wastes into and out of the cell.More importantly, they control the water that goes in and out.Plants must have good water controlling systems (系统), allowing them to keep water during dry seasons, and get rid of unnecessary water. Plants can't walk around to find water, so being able to control water is very important.
So there you have it , what a plant cell wall is. Of course, there are many other things that are not talked about here. Knowing more about plant cell wails requires further study and research.From the first two paragraphs we can find that _____.
| A．all plants have a ceil wall |
| B．plant cells and animal cells are the same |
| C．different kinds of plant have different cell walls |
| D．there are no differences between the cells of a tree and a dog |
The underlined word "bent" in the passage is the closest in meaning to _____.
| A．变形的 | B．防水的 | C．太阳灼伤的 | D．表皮破损的 |
Cells in the trunk of a tree are _____ those on a leaf.
| A．as flexible as | B．not so flexible as |
| C．more important than | D．less important than |
What is the most important use of a plant cell wall?
| A．To protect the plant. | B．To provide support. |
| C．To move chemicals and wastes. | D．To control the water. |
Clothing is a language. It tells us about individual people: their personality, their age, their place in society and so on. If we want to know more about society, we can look at traditional clothing. 
The continent of Africa has a long history and a rich culture, and this is shown in traditional dress. You often find three colours — red, gold and green in the clothing. The first colour stands for the blood of millions of people who suffered as slaves(奴隶); the second is for the rich resources of the African earth; and the third represents the grasslands of home.
The patterns(图案) on the clothing also have a meaning. A common pattern is in the form of a cross “×”, which stands for “unity”. Another pattern is a rectangular box, which represents “strength”.
Because clothing has a strong social meaning, people are very careful in choosing what to wear. It would be a serious mistake to wear the wrong clothing, or to wear clothes in the wrong way. For instance, in Ghana, a woman should wear her waistband differently according to the importance of the social event.
Traditional dress also tells us about everyday life. African designs are famous for loose(宽松的) clothing. The climate, with the hot sun and wide temperature ranges(变化), requires that the clothes are comfortable for daily life.
Although many people wear western clothes, particularly in the big cities in Africa, traditional dress is very highly valued(评价). This is because it has deep cultural meanings.According to the passage, red ________.
| A．represents the setting sun |
| B．stands for African unity |
| C．is chosen because it is a bright colour |
| D．is a reminder(暗示) of the sad history in Africa |

| A．it has deep cultural meanings |
| B．people wear it in the big cities |
| C．it needs to protect people from the climate |
| D．it needs to keep people dry in the rainy season |
According to the passage, which sentence is NOT RIGHT?
| A．African dress has deep cultural meanings. |
| B．Africa has a long history and a rich culture. |
| C．The rectangular box in the pattern represents “strength”. |
| D．People in the big cities in Africa prefer to wear western clothes. |
