Food for space has to be packed in special ways. Some of it goes into tubes that a man can squeeze into his mouth. Bite-sized cookies are packed in plastic.
There is a good reason for covering each bite. The plastic keeps pieces of food from travelling in the spaceship. On the earth very small pieces of food would simply fall to the floor. But gravity doesn' t pull them to the floor when they are out of the plastic in a spaceship. (78) They move here and there and can get into a man' s eyes or into the spaceship' s instruments. If any of the instruments is blocked, the astronauts may have trouble getting safely home.
As astronauts travel on longer space trips, he must take time to sleep. An astronaut can fit himself to his seat with a kind of seat belt. Or, if he wants to, he can sleep in a sleeping bag which is fixed in place under his seat. But be careful he must put his hands under the belt when he goes to sleep. This is because he is really afraid that he might touch one of controls that isn' t supposed to be touched until later.
Why would astronauts cover each bite of food in space？
A．Because small pieces of food would fall down to the floor.
B．Because weightless pieces of food might make trouble when they travel around.
C．Because they haven' t enough food for longer trips.
D．Because astronauts don' t want to waste food.
In 1970, a young German schoolmaster had an idea which changed this state of affairs. He decided to turn his little schoolhouse into a dormitory or hostel for the summer holidays. Anyone who brought his sleeping bag and cooking equipment along could stay there for a very small quantity of money. The idea was a success. A few years later, the schoolhouse was much too small to hold the many young people who wanted to stay there. As a result, a dormitory was set up in an old castle nearby. This was the first Youth Hostel.
Today, young students and workers of every country can meet in the hostel and get to know each other. When young people arrive at the hostel, they have only to show their card of membership in a hostel organization in their own country. This card will permit him to use the facilities of hostels all over the world for very low prices.
Often, at the evening meal, a group of boys and girls from various parts of the country or the world will happen to meet at the same hostel. They may put their food together and prepare a dinner with many kinds of dishes. Sometimes a program will be organized after the meal with dances, songs, or short talks followed by a question period. One can learn a lot of things about other places, just by meeting people who come from those places. For this reason, a few weeks spent "hostelling" can be just as useful a part of one's education as classes in school.
The author says children in the city seldom went to the woods and fields because
A．all these places were too far away for them to go between morning and nightfall
B．it was impossible for them to go and get back in one day
C．they were not old enough to take such a trip
D．they were not permitted to go to these places
“In my opinion,” the first man said, “the Egyptian pyramids(埃及金字塔)are the world’s greatest wonder. Although they were built thousands of years ago, they are still standing. And remember: the people who built them had only simple tools. They did not have the kind of machinery that builders and engineers have today.”
“I agree that the pyramids in Egypt are wonderful,” the second man said, “but I do not think they are the greatest wonder. I believe computers are more wonderful than the pyramids. They have taken people to the moon and brought them back safely. In seconds, they carry out mathematical calculations that would take a person a hundred years to do.”
He turned to the third man and asked, “What do you think is the greatest wonder in the world？”
The third man thought for a long time, and then he said, “Well, I agree that the pyramids are wonderful, and I agree that computers are wonderful, too. However, in my opinion, the most wonderful thing in the world is this thermos.”
And he took a thermos out of his bag and held it up.
The other two men were very surprised. “A thermos？” they exclaimed. “But that’s a simple thing.”
“Oh, no, it’s not,” the third man said. “In the winter you put in a hot drink and it stays hot. In the summer you put in a cold drink and it stays cold. How does the thermos know whether it’s winter or summer？”
