【題目】 Hard Work Makes Dreams Come True

Astronaut Ellen Ochoa shows that with a good education and hard work, you can reach for the stars. Ochoa is the first Hispanic astronaut woman to fly into space.

As a child, Ochoa didn’t know what she wanted to be when she grew up. But her mother always told her to stay in school and study hard. She listened to her mother. When she was 13 years old, she won a spelling contest. In high school, Ochoa spent many hours each week studying for all her classes. She finished with the best grades in her class. After high school, Ochoa went to college. One day in college she heard that the U.S. government had chosen six women to become astronauts. At that time, Ochoa decided to become an astronaut, too.

Her many years of hard work paid off at last. She was asked to be an astronaut in 1990. In April, 1993 in the space shuttle(航天飛機(jī)) named Discovery, she made history by becoming the first Hispanic woman to travel to space. Ochoa and the other astronauts had many jobs while on the Discovery. One of her tasks was to use the shuttle’s robot arm to move large objects. Ochoa used a computer to make the arm pick up a satellite and put it into space. A satellite is a spacecraft that moves around the earth or some other objects. Satellites can take pictures and gather information about planets and stars. During her second trip in 1994, she used the robot arm again. She used the arm to pull in a satellite from space. The satellite had been used to study the air around the earth. Then Ochoa went to two more shuttle trips. Altogether, she spent a whole month in space. That’s more than 700 hours.

Ochoa knows that she is a hero to many young people. She often tells them the same thing her mother told her when she was a little girl. “Get a good education and believe in yourself,” says Ochoa.

【1】When did Ochoa decide to become an astronaut?

A. When she was in college.B. When she was 13 years old.

C. Before she went to high school.D. After she went to work.

【2】On the Discovery, Ochoa used the robot arm to ______ .

A. repair the shuttle’s computerB. take pictures of the earth

C. gather information about planetsD. put a satellite into space

【3】Ochoa probably advises the young people to ______ .

A. fly into space one dayB. become scientists some day

C. do their best in schoolD. learn how to use robot arms

【題目】

Jim didn't like to be kissed. But people loved to kiss Jim! Both of his grandmothers and all of his aunts would kiss his face and say “You are just the cutest thing.”

Jim’s best friend, Ben, lived next door. Ben would always laugh at him. “Kissy Face! Kissy Face!”

Jim didn’t know what to do. He tried hiding when family came to visit. But his father always called him in to say hello. He tried wearing an old Halloween mask(面具), but his mother made him take it off so his grandmothers and aunts could see his “cute little face.” Jim even tried to make his face and hands sticky（黏糊的），but the grandmothers and aunts just wiped off the stickiness and kissed him even harder.

The big day finally came. Jim’s parents brought the new baby home. So the whole family held a big party but this time not for Jim. Soon the whole family arrived. Jim felt worried about being kissed.

Then one of the aunts came over to Jim. “Well, you’re a big brother now,” she said. Instead of kissing his face, she just patted his shoulder and smiled.
