In Britain ,people often invite friends for a meal , a party or just coffee. People who know each other very well may visit each other’s houses without  an invitation(邀请),but if we invite new friends, usually an invitation is needed. When people invite someone to their homes , they often say ,“Would you like to come for dinner on Saturday ?” Answers are, “Thanks, we’d love to. What time?” or “I’m sorry, We’d love to ,but we have tickets for the concert.” However, it is not polite to say,“No, we wouldn’t.”
Sometimes, the British use expressions that sound like invitations but which are not invitations. For example. “You must come over for a drink sometime .” or “Let’s go out for a meal one of these days.”  These are usually just polite ways of ending a talk . They are not real invitations because they don’t mention an exact time or day. They just show that the person is trying to be friendly and the answers are ,“Yes , that would be nice .” or “OK, yes ,thanks.”
So next time you hear what sounds like an invitation, listen carefully. Is it a real invitation or is the person just being friendly?
【小题1】It’s always necessary for        to visit each other’s houses with an invitation.

Space travel is nothing new. The first spacecraft with a human was sent up into space in 1961. Since then, people have not only traveled to space, but also many of them have lived there in space stations for some time.
The Soviet Union(前苏联) sent the first space station into space in 1971. This space station was called Salyut 1. Salyut 1 was designed as a place where people could live while they observed space and did experiments. The first group of astronauts lived there for 23 days. The Soviet Union went on to make seven more Salyut space stations. At about the same time, the United States built its own space station, called Skylab.
Astronauts visited and often lived in these space stations for a short time. However, it wasn’t until the late 1980s when The Soviet Union sent the Mir space station that people began to live in space for a longer time. Mir stayed in space from 1989 until 2001, when it was decided that the space station was too old and no longer safe to live in.
Living in space stations seems to be fun, but astronauts face many problems. One of them is food. All the meals on space station are put together on Earth and sent there by space shuttle. Because the food has to last a long time (sometimes up to three months), a lot of it has to be stored in cans. The space station does not have a fridge, but it has a cool room to keep fruit and vegetables fresh. Astronauts also eat many other foods such as dried meat that do not need special care.
Without the help of gravity, sitting down to eat can be tough. Astronauts sometimes have to fix themselves to the wall while eating. They also have to be very careful to that food does not float away.
【小题1】Which of the following has the closest meaning to the underlined word “observed” in Paragraph 2?
