Among all the fast growing science and technology, the research of human genes（基因）, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.
The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied（应用）, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span(寿命) can be prolonged.
Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial family being a good example, have hereditary diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientists just need to find the wrong gene and correct it and a healthy child will be born.
Some people are worrying that the gene research can be used to manufacture (produce) human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep; therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.

Here’s an amazing way to get a hard-boiled egg into a bottle, even though the mouth of the boiled is smaller than the egg! What’s more, you don’t even need to touch the egg to get it to go in!
For this experiment you will need:
·a hard-boiled egg
·a glass bottle with a mouth just slightly smaller than the egg (a fruit-drink bottle works well)
·a 8-cm by 8-cm(3-inch by 3-inch)piece of newspaper
·a match
Remove the shell from the egg. Set the egg on the mouth of the bottle to see that the egg does not fit through the mouth.
Light the paper. Remove the egg from the mouth of the bottle and drop the burning paper into the bottle. Before the fire goes out, set the egg back onto the mouth of the bottle. Within a few seconds the egg will squeeze(挤) through the mouth and into the bottle.
As it entered the bottle, the egg may have broken into pieces. This happens when the diameter(直径) of the egg is more than about 0.5 cm(about 3/16 inch) larger than the diameter of the bottle’s opening.
Why does the egg slide into the bottle, even though no one is pushing it? Because the pressure of the air is pushing it. Before the burning paper is put into the bottle, the pressure of the air inside is the same as outside. The burning paper, however, heats the air inside. This causes the air inside to expand. When the egg is placed on top of the bottle, it seals(封住) the bottle. When the fire goes out, the air inside cools. As it cools, the air contracts(紧缩), and the pressure of the air inside becomes less than the pressure outside. Then, the higher outside pressure pushes the egg into the bottle!

1.
The best title of this passage can be .
1. A.
  An interesting story
2. B.
  The pressure of the air
3. C.
  Egg in a bottle
4. D.
  Egg, bottle and match

2. B.
  Water.
3. C.
  Bottles.
4. D.
  Paper.
3.
Why will the egg break into pieces while entering the bottle?
1. A.
  Because of the burning paper.
2. B.
  Because the diameter of the egg is too larger than that of the bottles opening.
3. C.
  Because it is cool inside the bottle.
4. D.
  Because the pressure of the air inside is larger.
4.
What is the most important to get the egg into a bottle?
1. A.
  A match.
2. B.
  A fruit-drink bottle.
3. C.
  The pressure of the air.
4. D.
  The burning paper.
