When he got dressed he got blood all over his clean shirt, so he had to find another one. The only other shirt that was clean needed ironing(熨), so he ironed it.

He showed him where the meter was, said good-bye and found that the iron had burnt a hole in his shirt. So he had to wear the one with the blood on it after all.

The food we eat seems to have a great effect on our health. Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of human illness is related to food and forty percent of cancer is related to food as well. That food is related to illness is not a new discovery. In 1945, some researchers realized that things commonly used to keep colour in meats and other food additives(添加剂)caused cancer.
Yet, these additives remain in our food, and it is difficult to know which things on the wrappings(包装)of foods are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to their animals, and because of this, penicillin has been found in the milk of cows. Sometimes similar tings are supplied to animals not for their health, but just to make a profit.
The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although some countries have tried to control such things, the practice continues.
66. According to this passage, we can know .
A. perhaps most of human illness is caused by what we eat
B. perhaps most kinds of cancer are related to what people eat
C. cancer was discovered in 1945
D. science has made food unfit to eat

A. harmful B. useless C. helpless D. dangerous

A. are bright and colourless
B. are not bright and colourful
C. have indirect effects on our health
D. have direct effects on our health
69. People use additives .
A. to make food more unfit to eat
B. to improve the colour and taste of the food
C. to change colour of the food
D. to take off the diseases of the food
70. Which of the following is not true?
A. Some wrappings of food are harmful.
B. Farmers try to make more money on the market by fattening their animals.
C. “The practice continues” means “things are still going on like that”.
D. We needn’t take care of what we eat.
D
At first, the earth’s surface layer(层)was made up of huge blocks of hard, solid rocks. Then slowly, there rocks broke up into smaller and smaller pieces. Finally stones, pebble(卵石)and grains of sand were formed. Many sorts of plants and animals lived and died on the surface of the earth. Their remains mixed up with the stones, pebbles and formed soil. The outmost layer of the earth is soil.
There are many ways in which large pieces of rock break into smaller ones. Wind, water, heat and cold help to break up rocks. When winds blow grains of sand against a large rock for a long time, the softer layers of the rock are slowly worn away. These leave holes and crack(裂缝)in the rock, which become bigger and finally the rock breaks up into smaller pieces.
The moving water of streams and rivers also help to break up rocks. As the water moves along, it carries with it small pieces of rock. These rub the larger ones. Thus, the larger rocks are worn down to smaller pieces.
The heat of the sun is also helpful to breaking up rocks. When the sun shines, the rocks become very hot. If these rocks are suddenly cooled, they may crack. Ice also plays a part in making soil. Water in the cracks can turn into ice in cold weather. As this happens, it becomes bigger and the cracks become wider, and finally break into smaller pieces.
71. According to the passage, soil .
A. forms very slowly
B. is a mixture of stones, pebbles and sand
C. make up the layers of the earth
D. is becoming smaller and smaller
72. How many factors are mentioned in helping the forming of soil?

C. Five. D. More than five.
73. Which of the following speeds up the breaks of rocks most?
A. Hot weather. B. Cold water.
C. Sharp changes in temperature.
D. More dead plants in the cracks.
74. Which of the following is NOT true?
A. The remains of many plants of animals formed soil.
B. If a large rock never moves, it will never break up.
C. Even if a large rock never moves, it will break up.
D. Ice in the cracks helps to break up rocks
75. The best title for this passage should be .
A. Soil from Rocks
B. Ways to Break up Rocks
C. Soil on the Earth
D. Soil, Outmost Layer of the Earth

Do you know that you can use your watch as compass(指南针)on a sunny day? Look at the watch which is on your hand and point the hour hand in the direction of the sun. Imagine a line which runs from the center of the watch through a point halfway between the hour hand and number one. This line will point south.
In the northern half of the earth the sun is in the south at noon. In our country the real noon is one o’clock. If at that time we point the hour hand at the sun, the hour hand and number one will point south. That’s why you must imagine a line which will run from the center of the watch through a point halfway between the hour hand and number one. It will point south.
If you are in the southern part of our planet, you must point number 12 at the sun. The line which you can imagine between number twelve and the hour hand will then show north.

五、书面表达
One possible version,
It is difficult to imagine what life would be like without water. Water is very important to all living things. There would be no life without water.
Water shortage has become a serious problem. One reason for this is that the growing population and the development of industry and agriculture need much more water. Another is that water is being wasted in some areas.
Therefore, measures must be taken to solve this problem. First of all, we must make good use of water and avoid polluting it. In addition, we can get useful water through purifying rain water or sea water.
