英语：21.1《Human Biology》教案(北师大版选修7)
Unit 21 Human BiologyLesson 1 Super AthletesGrammar : Conditionals Revision1．条件句有两类，一类是真实条件句，一类是虚拟条件句。
2．如果假设的情况是有可能发生的，就是真实条件句（Zero conditional）。
真实条件句中的谓语用陈述语气。
Eg。
If it doesn’t rain tomorrow, we will go to the par.如果明天不下雨,我们就去公园.3.如果假设的情况是过去或现在都不存在的,或将来不大可能发生的,则是虚假条件句,共有三种情况.Eg. If he had seen you yesterday, he would have asked you about it.如果他昨天见到你,他会问你这件事的.(事实上他昨天没有见到你,因此也未能问你这件事.)4.在含有虚拟条件句的复合句中,主句和从句的谓语都要用虚拟语气.虚拟条件从句和主句的动词形式列表如下:5.虚拟条件句的用法1)表示与现在事实相反的假设和结果(1st conditional)Eg. If I were you,I should/could/would/might tell him the truth.如果我是你,我就会/可能对他说实话.If he had time, he would/could/might go with you.如果他有时间,他就会/可能和你一起去.If my brother were here,everything would be all right.要是我哥哥在这儿,一切都没问题了.2)表示与过去事实相反的假设和结果(2nd conditional)Eg. If you had taken my advice, you wouldn’t/couldn’t have failed in the exam.如果你按照我的建议去做,你不会/不可能考试不及格.If I had had the money last week, I should/would/could/might have bought a car.如果我上星期有了这笔钱,我就会/可能买辆车.She would/could/might have telephoned you immediately, if she had won the game.如果她比赛赢了,她就会/可能给你打电话.If you had come a few minutes earlier, you would/could/might have met the famous singer.如果你早来几分钟的话,你就会/可能会见到那个著名的歌唱家.3)表示与将来事实可能相反的假设和结果(3rd conditional)Eg. If it were Sunday tomorrow, I should/would/could/might go to see my grandmother.如果明天是星期天,我就/可能去看我的奶奶.If it were to snow this evening,they would not go out.如果今晚下雪,他们就不出去了.If it should rain,the crops would/could/might be saved.如果下雨,庄稼就一定/可能有救.6.主,从句的动作发生时间不一致的情况(mixed conditional)有时条件从句中的动作和主句中的动作发生的时间不一致,这时动词的形式要根据它所表示的时间加以调整.Eg. If you had listened to the doctor, you would be all right now.如果你当初听了医生的话,身体现在就好了.(从句动作指过去,主句动作指现在) If you had practiced speaking English more, you would be able to speak it fluently.如果你多练习讲英语,现在就能讲得很流利了.。
