None of our early ancestors could digest milk as adults because their bodies never had to ----milk drinking simply wasn’t an option. As people began to extract milk from animals, though, some people developed the ability to keep drinking it throughout their lives.

     Scientists now know of a milk-related mutation ( 变异) in our genes -- the chemical instructions for life that we carry in almost every cell in our bodies. People who have a mutated form of one particular gene can drink milk just fine. People without the mutation tend to get sick from milk.

     To figure out where, and possibly why, milk drinking started, some scientists have been looking at who has the milk-digesting mutation today. Patterns are striking.

     Most adults in Northern and Central Europe are able to digest milk -- and they do. Cheese and butter and other dairy products are popular in countries such as Sweden, Denmark, Germany and England. Because European settlers dominated North America, most people here can handle milk just fine, as well. That may explain why ice cream is such a popular dessert in the United States.

     In much of Africa, Asia and South America, on the other hand, people tend to avoid dairy products because they lead to diarrhea (腹泻) and other stomach problems. (That’s why you won’t typically find cheese on the menu at a Chinese, Japanese or Ethiopian restaurant.) Native

Americans are also unable to digest milk.

     Based on these genetic patterns, scientists have long thought that- milk drinking started inNorthern Europe, where dairy is an institution and the milk-digesting mutation is everywhere.

     A recent study painted a different picture. With a computer medal, Thomas and colleagues looked at the spread of the milk-drinking mutation, farming and other related factor. Working backward, the scientists concluded that the first milk-thinkers lived in Central Europe around what’s now Hungary about 7,500 years ago. The practice didn't start farther north, as scientists had thought before.

阅读下面的短文，然后按照要求写一篇150词左右的英语短文。

Getting up early has been regarded as a good habit since ancient times．Many years ago, people thought that if we went to bed early and got up early, we would be energetic the whole day．So, getting up early is of great importance to us all．

In fact, morning is the best time of a day．In the morning, the air is the freshest and people are usually in the best conditions．Many of us may have the experiences that we memorize some things more quickly and accurately in the morning than at any other time of the day．If we do some morning exercise or only take a short walk in the morning, we can build our bodies and become much healthier．Also we will have enough time to make a plan and get ready for our work or study of the day if we get up early．However, if we get up late, we'll probably have to do everything in a great hurry．

Let us remember getting up early is a good habit and try our best to keep it．If we stick to getting up early every day, we will certainly benefit a lot from it．

When a cat is frightened, its heart starts beating faster, its muscles get tense, and there are changes in the chemicals in its blood stream. If the danger continues, it will defend itself, or it will run away as fast as possible.

Something like this also happens to people. When we are excited, angry, scared or aroused by other emotions, our bodies go through many physical changes, all of which make us more alert and ready to react. We, too, get ready to defend ourselves or run．Human beings, however, have a problem that animals never face. If we give way to our feelings and let them take over, we can get into trouble. Have you ever said something in anger ― or hit somebody － and regretted it later? Have you ever shouted at a teacher, told somebody you were lonely, or said you were in love, and then wished later you had kept your mouth shut? It isn’t always wise to express your feelings freely.

Does this mean that it’s smarter always to hide our feelings? No! If you keep the feelings of anger, sadness, and bitterness hidden away or bottled up inside, your body stays tense. Physical illnesses can develop, and you can feel disturbed badly inside．It can actual1y be bad for your health.

Feelings that you keep all bottled up inside don’t just go away. It’s as if you bought some bananas and stuck them in a cupboard. You might not be able to see them, but before long you’d smell them. And if you opened the cupboard, chances are that you’d see little fruit flies hovering all over them. They’d be rotten.

You can try to treat emotions as if they were bananas in the cupboard. You can hide them and you can pretend they don’t exist, but they’ll still be around. And at last you’ll have to deal with them, just like those bananas.

72. By taking a cat as an example, the author wants to show us that         .

A. animals can’t control their feelings

B. people can’t control their feelings

A. we are not as alert as animals

B. we sometimes can’t control our feelings

C. we always do something wrong to other people[来源:ZXXK]

D. we don’t pay attention to our physical changes

74. The author wants to tell us in the last two paragraphs that        .

A. we won’t be able to completely get away from our feelings .

B. we should treat emotions like bananas in a cupboard

C. feelings will gradually disappear when we hold them in

D. it’s good for our health to keep pleasant feelings

75. What would be the best title for the passage?

A. Frightened Cats and Human Beings        

B. Feelings and Bananas

C. Deal with Feelings Wisely
