阅读理解。 It's sometimes said that the English are polite people. This can make life difficult for foreigner. Suppose a foreign boy asks an English girl to go out with him and she says, ' If I finish my work, I'll meet you in the café at 7 o'clock,' Is she saying ' yes' or ' no' to his invitation? In grammatical terms, she is using the conditional structure. By using the conditional, speakers of English can avoid giving a 'yes' or ' no' answer to a question. It enables people to be diplomatic. If the girl doesn't want to go out with the boy, she won't turn up at the café. She will let him understand she is still work ing. If she wants to go out with him, but doesn't want to appear too easy to catch, she has achieved that with her reply. But in this case, as she uses the first conditional which s hows probability, she is quite likely to turn up at the café. Being polite can make life very difficult! The conditional is often used by people in the news-politicians, for example-who to avoid speaking out their ideas. Th is is very important if they are on their way to discuss an agreement. No one wants to give away his or her points before he or she starts. A government spokesman might say to a group of workers, ' if we could pay you more, we would.' The use of the conditional here makes room for argument although the speaker is using the second conditional form, which shows improbability. So it is unlikely the workers will get their rise. 'If' is a small word, which appears often in the English language. It can show politeness, reported speech and conditionals such as the First-probability-if I can come to your party, I will; the second -improbability-if I saw you tomorrow, I'd give you the book; and the third-impossibility( meaning it is too late to change something that has happened)-if you have told me.
