题目列表(包括答案和解析)
It is natural that children are curious (好奇的) about the world around them. For example, they want to know how their hearts beat. They want to know why the ocean water tastes salty.
As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. They become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (生涯、职业) in science.
Scientists spend their lives trying to find out about the world. Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry .
These scientists have already discovered a lot about our world. For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump (泵) that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.
Of course, scientists cannot answ
er all of our questions. If we ask, “Why does the ocean water taste salty” scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , “What happens to the salt in the ocean? The ocean does not get saltier every year.” Scientists are not sure about the answer to this question.
We know a lot about our world, but there are still many answers that we do not have, and we are curious.

John H. Johnson was born in a black family in Arkansas City in 1981. His father died in an accident when John was six. He was reaching the high school age, but his hometown offered no high school for blacks.
Fortunately he had a strong—willed caring mother. John remembered that his mother told him many times, “Son, you can be anything you want really to be if you just believe.” She told him not to depend on others, including his mother. “You have to learn success” she said. “All the people who work hard don’t succeed, but the only people who do succeed are those who work hard.”
These words, came from a woman with less than a third grade education. She also knew that believing and hard work don’t mean everything. So she worked hard as a cook for two years to save enough to take her son, who was then 15, to Chicago.
Chicago in 1933 was not the promised land that black southerners were looking for. John’s mother and stepfather could not find work. But here John could go to school, and here he learned the power of words--as an editor of the newspaper and yearbook at Du Sable High School. His wish was to publish www..coma magazine for blacks.
While others discouraged him, John’s mother offered him more words to live by “Nothing beats a failure but a try.” She also let him pawn（典当） her furniture to get the $ 500 he needed to start the Negro magazine.
It is natural that difficulties and failures followed john closely until he become very successful. He always keeps his mother’s words in mind:” Son, failure is not in your vocabulary!” Now John H. Johnson is one of the 400 richest people in America--worth $150 million.
What does the story mainly want to show us?
A. The key to success for blacks.
B. The mental support John’s mother gave him.
C. The importance of a good education.
D. How John H. Johnson became successful.
Why did John’s mother decide to move to Chicago?
A. Because his father died when John was very young.
B. Because life was too hard for them to stay on in their hometown.
C. Because John needed more education badly.
D. Because there were no schools for Negroes in their hometown.
Which of the following statements is TRUE according to the passage?
A. John’s mother didn’t believe in or depend on others.
B. John’s mother believed one would succeed without working hard.
C. John’s mother thought one could be whatever one wanted to be.
D. John’s mother thought no one could succeed without working hard.
What does the underlined sentence “Nothing beats a failure but a try.” in Passage 5 mean?
A. No failure can be beaten unless you try.
B. If you try, you would succeed.
C. A try is always followed by a failure.
D. A failure is difficult to beat, even if you try.
