阅读短文，选择正确答案。

    It is sometimes said that the English are polite people. This can make life difficult for foreigners. 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 cafe

at 7 o'clock." Is she saying "yes" or "no" to his invitation? 

    In grammatical terms, she is using the conditional structure (表示条件的句式). By using the conditional,

speakers of English can avoid (避免) giving a "yes" or "no" answer to a question. It enables people to be

diplomatic(婉转的). If the girl doesn't want to go out with the boy, she won't appear at the cafe. She will let him

understand she is still working. If she wants to go out with him, but doesn't want to appear too easy to catch,

she has achieved (达到) that with her reply. Here she uses the first conditional which shows probability, it seems

that she will go to the cafe. Being polite can make life very difficult!

    The conditional is often used by people like politicians (政客), for example--who wish to avoid speaking out

their ideas. This 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 often appears 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, I would have helped you.
