Not long ago, people thought babies were not able to learn things until they were five or six months old. Yet doctors in the United States say babies begin learning on their first day of life.

Scientists note that babies are strongly influenced by their environment. They say a baby will smile if her mother does something the baby likes. A baby learns to get the best care possible by smiling to please her mother or other caregivers. This is how babies learn to connect and communicate with other human beings.

One study shows that babies can learn before they are born. The researchers placed a tape recorder on the stomach of a pregnant woman. Then, they played a recording of a short story. On the day the baby was born, the researchers attempted to find if he knew the sounds of the story repeated while in his mother. They did this by placing a device in the mouth of the newborn baby.

The baby would hear the story if he moved his mouth one way. If the baby moved his mouth the other way, he would hear a different story. The researchers say the baby clearly liked the story he heard before he was born. They say the baby would move his mouth so he could hear the story again and again.

Another study shows how mothers can strongly influence social development and language skills in their children.

Researchers studied the children from the age of one month to three years. The researchers attempted to measure the sensitivity of the mothers. The women were considered sensitive if they supported their children’s activities and did not interfere (干涉) unnecessarily. They tested the children for thinking and language development when they were three years old. Also, the researchers observed the women for signs of depression (消沉).

The children of depressed women did not do as well in tests as the children of women who did not suffer from depression. The children of depressed women did poorly in tests of language skills and understanding what they hear.

These children also were less cooperative and had more problems dealing with other people. The researchers noted that the sensitivity of the mothers was important to the intelligence development of their children. Children did better when their mothers were caring, even when they suffered from depression.

1. According to the passage, which of the following is NOT the factor that influences intelligence development in babies?

A. The environment.　　　　　　 　　 B. Mother’s sensitivity.

C. Education before birth.　　　　 D. Their peers (同龄人)

2. What is the purpose of the experiment in which newborn babies heard the stories?

A. To prove that babies can learn on the first day they are born.

B. To prove that babies can learn before they are born.

C. To show mothers can strongly influence intelligence development in their babies.

D. To indicate early education has a deep effect on the babies’ language skills.

3. Which group of children did the worst in tests of language skills?

A. The children of women who did not suffer from depression.

B. The children of depressed but caring mothers.

C. The children of depressed mothers who cared little for their children.

D. The children with high communication abilities.

4. What is the main idea of the passage?

A. Scientific findings about how intelligence develops in babies.

B. Scientific findings about how the environment has an effect on babies’ intelligence.

C. A study shows babies are not able to learn things until they are five or six months old.

When we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.

People who are near-sighted can only see things that are very close to their eyes. Everything else seems unclear. Many people who do a lot of work such as writing, reading and sewing become near- sighted.

However, people who are far-sighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm's length. If they want to do much reading, they must get glasses, too.

Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatisms (散光). This, too, can be corrected by glasses. Some people's eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.

1.________ eye problem(problems)is(are)mentioned in the passage.

九年级英语单选题中等难度题查看答案及解析

Tomatoes are one of the world's oldest foods. They were discovered by the Indians of South America thousands of years ago. The first tomatoes were very small. By the time the Europeans brought them to Europe in the 1500s, they were larger. They looked more like the tomatoes we eat today.

When tomatoes first arrived in Italy, they were known as “love apples”. Italians believed that if you ate a tomato, you would easily fall in love.

In the United States, people believed that tomatoes were poisonous, and that you would die immediately after eating one. It wasn't easy to persuade people otherwise.

That was, until 1820, Robert Johnson decided to prove people wrong. He announced that he would publicly eat one bushel of tomatoes—about 50. A huge crowd showed up to watch. They were sure that Mr. Johnson was going to die. Of course, he survived. And the tomato went on to gain a big place in the American diet.

In the beginning, people argued whether a tomato was a fruit or a vegetable. From a purely scientific point of view it is a fruit. A fruit is the ripened ovary of any plant that makes seeds. However, this didn't stop most people from calling it a vegetable. They reasoned that tomatoes are eaten with the main meal—just like vegetables.

They are not eaten as dessert, like other fruits such as apples or bananas. Therefore, they thought the tomato must surely be a vegetable.

Fruit or vegetable, tomatoes have survived for a long time. They are not likely to disappear any time soon. They are just too good to eat.
