American scientists have developed the first material that repairs itself. The material is a form of plastic that has been engineered to fill breaks in its surface.
Plastics are used today in everything. Scientists wanted to find a way to make objects made of plastic last longer. The researchers hope their new discovery can be used to make objects that are difficult or impossible to replace.
The surface of plastic objects breaks over time. Very small breaks develop every time a plastic object is used. The researchers wanted to find out how to stop plastic from developing small breaks that weaken and destroy it. They found the answer in the chemical structure of plastic itself. The research team found a way to make plastic that contains very small balloons filled with monomer(单体) liquid. When the new plastic cracks, the monomer liquid is let out and flows into the crack. Thus the break is repaired. The repaired plastic has seventy-five percent of the strength of undamaged plastic.
The new self-repairing plastic is not yet ready for production. But it has several possible uses. One could be in space vehicles where parts cannot be repaired or replaced. Another possible use might be in bridges. And it could be used in people, to replace bone joints that have become broken or damaged.
1.The passage mainly talks about_______ .
A. plastic that repairs itself
B. the chemical structure of plastic
C. permanent material invented
D. small balloons that makes plastic stronger
2.We know from the passage that the repair is done as_______.
A. the cracked plastic parts are changed
B. the plastic cracks
C. the liquid is put into the plastic cracks
D. the plastic is made
3.The scientist are planning to use the new material in space vehicles, bridges and people because________.
A. the plastic parts in them are required to last longer
B. they want to experiment in these places first
C. the new material cannot be used elsewhere
D. the plastic parts in them are easily broken or damaged

If we are to help students develop reading skills in a foreign language, it is important to understand what is involved in the reading process itself. If we have a clear idea of how “good readers” read, either in their own or a foreign language, this will enable us to decide whether particular reading techniques are likely to help learners or not.
In considering the reading process, it is important to distinguish between two quite separate activities: reading for meaning (or “silent reading”) and reading aloud. Reading for meaning is the activity we normally engage in when we read books, newspapers, road signs, etc.; it is what you are doing as you read this text. It involves looking at sentences and understanding the message they convey, in other words “making sense” of a written text. It doesn’t normally involve saying the words we read, not even silently inside our heads; there are important reasons for this, which are outlined below.
Reading aloud is a completely different activity; its purpose is not just to understand a text but to convey the information to someone else. It is not an activity we engage in very often outside the classroom; common examples are reading out parts of a newspaper article to a friend, or reading a notice to other people who can’t see it. Obviously, reading aloud involves looking at a text, understanding it and also saying it. Because our attention is divided between reading and speaking, it is a much more difficult activity than reading silently; we often stumble and make mistakes when reading aloud in our own language, and reading aloud in a foreign language is even more difficult.
When we read for meaning, we do not need to read every letter or every word, nor even every word in each sentence. This is because, provided the text makes sense, we can guess much of what it says as we read it.
1.The passage is mainly about ____________.
A. reading skills B. silent reading
C. reading processes D. reading aloud
2.The underlined word “stumble” in Paragraph 3 means ____________.
A. step over something and fall
B. repeat something or pause for too long
C. walk with heavy movements
D. speak in a fluent and confident way
3. We can infer from the passage that the author will continue to ____________.
A. discuss in detail how to read aloud
B. introduce some more reading activities
C. tell how good readers read in their own language
D. explain why we needn’t say the words when reading for meaning
4. We can conclude that ____________.
A. reading silently is easier than reading aloud
B. to understand a sentence, you have to read all the words in it
C. silent reading involves looking at a text and saying the words silently to yourself
D. there’s no difference between reading in one’s own language and in a foreign one
