THE HISTORY OF LIVING IN SPACE

Space travel is nothing new. The first spacecraft with a human on board blasted into space In 1961. since then, people have not only been travelling to space, but many of them have also lived there for extended periods.

Food

All the meals on space stations are put together on Earth and sent to the space station, along with the astronauts, by space shuttle. Because the food has to last a long time (sometimes up to three months), a lot of it has to be preserved by dehydration or canning.

The space station does not have a freezer to preserve food, but It does have a cool room to keep fruit and vegetables fresh.

Astronauts also eat many other foods such as cereals, cereal bars, nuts and dried fruit that do not need any special preparation.

Eating

Astronauts have a set timetable each day. This tells them when to do everything, including when to have their meals. At meal preparation time, they start getting their food ready, which often includes adding water to re-hydrate the dehydrated foods.

Without the help of gravity, sitting down to eat can be tricky. Astronauts sometimes have to strap themselves and their food into place. Because of lack of gravity, astronauts cannot use ground salt and pepper, and all drinks must be taken from bottles. They also have to be careful that crumbs do not fly off and get stuck in vents and instrument panels.（選自《九年級(jí)下冊(cè)新理念英語(yǔ)閱讀》）

Even nowadays there are a lot of misunderstandings between nationalities. Let’s have a look at what the following people have to say.

Maria Conti: I find the English people insincere (虛偽), cold and unfriendly. They keep saying “Thank you”, “I’m sorry”, even when they don’t know each other. They are even polite to their own relatives! Except for helping you find your way in the streets, they aren’t really friendly and never invite you to their houses.

Giannis Sinios: On the contrary I found them both broad-minded and friendly. I was invited to people’s houses and they all showed great interest in my ideas, Greek life and people. In England I learned that it was possible to be warm, friendly and polite at the same time.

Judy Brown: I lived in both Italy and Greece for a few years. At first there were a few misunderstandings between my foreign friends and myself. For example, I once gave a Greek friend a present for her birthday. I was rather sorry that she didn’t unwrap it immediately. What’s more, she even didn’t thank me until I asked her if she liked it! I’ve learned from different experiences that a lot of foreigners find our attitude to what we English people call politeness is rather insincere. They feel that politeness isn’t necessary between friends.

1.According to Maria Conti, it is _________.

A. insincere to keep saying “thank you” and “I’m sorry” to strangers

B. necessary for relatives to be polite to each other

C. unfriendly for the English people to help your way in the streets

D. not polite for the English people to invite her to their houses

2.Giannis Sinios is from________.

A. England B. Greece C. Italy D. America

3.According to Judy Brown’s experience, ___________ .

A. what the English people call politeness is rather insincere

B. the English people are less polite than the people in other countries

C. ideas of what are good manners are the same in different countries

D. ideas of what is politeness are not always the same in different countries
