For centuries people dreamed of going into space. This dream began to seem possible when high-flying rockets were built in the early 1900s.
In 1903 a Russian teacher named Konstantin Tsiolkovsky figured out how to use rockets for space travel. His plan was the first one in rocket science to use correct scientific calculation. About 30 years later, a U.S. scientist named Robert Goddard built the first rockets that could reach high altitudes. During World War II, German scientists built large rockets that could travel very far and carry dangerous explosives. After the war, scientists from Germany went to the United States and the Soviet Union to help those countries build space rockets.
These two countries were soon racing to get to space first. Each of these countries wanted to prove that it was stronger and more advanced than the other one. Both countries also had powerful bombs. People in the United States were worried when the Soviets were first to launch a space satellite, which was called Sputnik. The Soviets were also first to send a person into space. Yury Gagarin orbited the earth in the Vostok I spaceship in 1961.
The US government set a goal for its space program to be the first country to put a person on the Moon. The U.S. space program built a series of Apollo spaceship. These vehicles were powered by huge Saturn 5 rockets. In 1969 Apollo II took three men to the moon successfully. Nell Armstrong became the first person to walk on the Moon.
The Soviets may have lost the race to fly people to the Moon, but they built the first space station in 1971. The United States also built a space station. The space stations allowed people to live and work in space. Then the Soviet Union and the United States cooperated to hook two spaceships together in space. This action ended the "space race". Today a much larger space station, built by several countries together, orbits Earth.
Another new way to go to space is by space shuttle. A space shuttle, first made in the United States in 1981, looks like an airplane. Astronauts who fly spaceships have used shuttles to help put satellites into space.

I was always told that the three Ps, patience, positive thinking and perseverance(毅力),were a sure path 31 success. But this advice does not always work as planned. My high school maths exam is one example. The exam, 32 was originally to be held in our classroom, 33 (change) to the library at the last minute.

I was on my way to the Taiyetos Mountains. The sun was setting when my car 31 (break) down near a remote and poor village. Cursing my misfortune, I was wondering where I was going to spend the night when I realized that the villagers who had gathered around me were arguing as to 32 should have the honor of receiving me 33 a guest in their house.

Millions of words have been said about young people in the United States. There are reasons 31 this great interest in their ideas, 32 (feel) and actions. Today there are about eight million Americans in the colleges and universities. The young under twenty-five make 33 nearly half of the American population, many of 34 will be in power in the U.S. 35 (nature) their ideas are important to everyone in the country, and 36 is necessary for the older people to understand 37 they think and feel. College students today have strong 38 (opinion) about right and wrong. They are deeply interested in making a 39 (good) life for all the people, especially for those 40 _____ have never been given a fair chance before.
More American people take their troubles with them on holiday, according to a new survey. 31 40 percent said that the main reason for going away is to escape 32 (press) from work, almost all said they worry more 33 they do at home. Only four in every one hundred said that they are happy and free of care.
The most common worry is burglary(入室盗窃), with four out of ten worrying about their homes 34 (break) into while they are abroad. More than a quarter feel they will feel crazy 35 some other noisy and rough holiday-makers and twenty-two percent worry they may be attacked 36 their possessions will be 37 (miss).
The survey also showed 38 the stay-at-home Americans are no more. Three out of every five want to have a holiday abroad, which was 39 increase from the figures only three years ago. The hotel holiday is still a winner, with about one third of all Americans 40 (prefer) to go on a self-catering(自助) holiday.
