Recently some American scientists have given a useful piece of advice to people in industrialized nations. They say people should eat more of the same kind of food eaten by humans living more than 10,000 years ago. ___【小题1】___
The scientists say that the human life has changed greatly. Our bodies have not been able to deal with these changes in lifestyle and this had led to new kinds of sickness. ___【小题2】___ So they are called “disease of civilization”. Many cancers and diseases of the blood system are examples of such diseases.
Scientists noticed that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none. __【小题3】___ However, a change in food is one of the main differences between life in ancient times and that of day.
Stone Age people hunted wild animals for their meat, which had much less fat than domestic ones. They ate a lot of fresh wild vegetables and fruits. They did not have milk or any other dairy product, and they made very little use of grains.
___【小题4】___ We eat six times more salt than our ancestors(祖先). We eat more sugar. We eat twice as much fat but only one third as much protein and much less vitamin C.

Before going outside in the morning, many of us check a window thermometer(温度计)for the temperature. This helps us decide what to wear.__【小题1】__. We want our food to be a certain coldness in the refrigerator. We want it a certain hotness in the oven. If we don’t feel well, we use a thermometer to see if we have a fever. We keep our rooms a certain warmth in the winter and a certain coolness in the summer.
Not all the thermometers use the same system to measure temperature. We use a system called the Fahrenheit scale. But most other countries use the Centigrade scale.
Both systems use the freezing and boiling points of water as their guide.__【小题2】__.
The most common kind of thermometer is made with mercury(水银)inside a clear glass tube. As mercury (or any other liquid ) becomes hot, it expands. As it gets colder, it contracts(收缩). That is why on hot days the mercury line is high in the glass tube.__【小题3】__.

Finally. Place a white card on the outside of the bottle and behind the straw. Now you can see the water lever easily. ____【小题5】____.
As the temperature goes down, the water will contract, and the lever in the straw will come down. Perhaps you will want to keep a record of the water lever in the straw each morning for a week.

What is your favourite colour? Do you like yellow, orange, red?   1  . Do you prefer greys and blues? Then you are probably quiet, shy, and you would rather follow than lead.

If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly.

   3   . A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day.   4  .
