What does it feel like to break a bone? It’s different for everyone, but the pain is often sharp. If the break is small, however, the person may not feel much pain at all. If you think that you or someone else has broken a bone, the most important things to do are to stay calm, make the hurt person comfortable, and call the doctor. Do not move the injured body part since movement could make it worse.

To treat the break, the doctor will need to take an X-ray. This gives the doctor the information he or she needs to set (接上) the bone: to put it back to its normal place. If the bone is large or it is broken in more than one place, the doctor may need to use metal pins (钢钉) to set it. After the bone has been set, the next step is usually putting on a cast, the special, hard thing that will keep the bone in place for a month or two.

Your bones are excellent at healing themselves. Broken bones will produce many new cells (细胞) and tiny blood vessels (血脉). These cover both ends of the broken part, and close up the break until the bone is as whole and strong as before.

47. When someone breaks his bone, the following should be done except ______.

A. asking the doctor for help   B. comforting the hurt person               

C. moving the injured part     D. staying calm

48. Which is the correct order to treat the break?

   a. take an x-ray                 b. use metal pins to set it

 c. put it back to its normal place    d. put on a cast

A. a→b→c→d                B. a→c→b→d  

C. a→d→c→b                D. d→a→b→c

49. The underlined word “heal” in Paragraph 3 is closest in meaning to “______”.

   A. break again                  B. become worse

C. wound or hurt                    D. become healthy again

50. Where would you probably read this passage?

   A. In a story book.            B. On a poster.       

C. In a health care book.        D. In a chemistry book.

Imagine that the genome (基因组) is a book. The book consists of 23 chapters with thousands of stories made up of paragraphs, words and letters on different levels. There are one billion words in the book, which makes it longer than 5,000 volumes the size of this book, or as long as 800 Bibles. If I read the genome out to you at the rate of one word per second for eight hours a day, it would take me a century. If I wrote out the human genome, one letter per millimeter, my text would be as long as the River Danube. This is an enormous document. A huge volume, a cook book of great length, and it all fits inside the extremely small nucleus (核) of a tiny cell that fits easily upon the head of a pin.

The idea of the genome as a book is not, strictly speaking, even a metaphor (比喻), It is true to a great extent. A book is a piece of digital information, written in one-directional form and defined by a code that translates a small alphabet of letters into a large dictionary of meanings through the order of their groupings. So is a genome. The only complication is that all English books read from left to right, while some parts of the genome read from left to right, and some from right to left, though never both at the same time.

While English books are written in words of different lengths using twenty-six letters. Genomes are written entirely in three-letter words, using only four letters, And instead of being written on flat pages, they are written on long chains of DNA molecules (分子), The genome is a very clever book, because in the right conditions it can both photocopy itself and read itself.

How do human genomes read according to the passage?

       A. Only from left to right.    B. Only from right to left.

       C. From both directions at the same time   D. From one direction at a time

We can learn from the passage that the human genome ______.

       A. is as long as the River Danube

       B. can be easily placed on the head of a pin

       C. is coded with and alphabet of four letters

       D. is smart enough to read and take photos of itself

It can be concluded that the passage is mainly written for ______.

       A. specialists in the field      B. general readers

       C. natural scientists        D. readers with academic background

The real purpose of the author’s comparison of the genome to a book is ______.

       A. to focus on the differences between the two

       B. to lay emphasis on the similarities between the two

       C. to simplify the concept of the human genome

       D. to give an exact description of the human genome

The effects of air pollution on natural conditions have been a disturbing problem for many years. Some scientists hold the view that the air inside houses may be more dangerous than the air outside. It may even be one hundred times worse.

Most scientists agree that every modern house has some kind of indoor pollution, which can cause a person to feel tired, to suffer eye pain, headache and other problems. Believe it or not, some pollutants can cause breathing diseases of blood and even cancer.

What made us feel relieved is that there’s growing concern about the problem now. It is true that when builders began constructing houses and offices they did not want to waste energy. To do this they built buildings that prevented or limited the flow of air between inside and outside. For the same purpose, man-made building materials were employed to build houses, which are now known to let out some harmful gases.

Facing the serious challenge, scientists have been searching for a way to handle the problem. To everyone’s delight, they discovered a natural pollution control system for building—green plants, though they do not really know how plants control air pollution. Scientists suppose that a plant’s leaves absorb or take in the pollutants and in exchange gives out oxygen through its leaves and tiny organizations on its roots. Therefore they recommend that all buildings should have one large plant or several small plants inside for every nine square meters of space. Because studies indicate that different plants absorb different chemicals, the most effective way to clean the air is to use different kinds of plants. In conclusion, having green plants inside your house can make it a prettier and healthier place. Why not try?

1.Which of the following statements is TRUR?

2.According to scientists, some kind of indoor pollution can be found in ________.

3.What does the underlined part “To do this” refer to in Para3?

4.The reason why we should use different kinds of plants to clean the air is that ___.
