7、What is he going to do when he grows up? 他長大了想干什么？ We are leaving for Xiamen tomorrow if it doesnt rain. 如果明天不下雨, 我們就去廈門。 We will buy that microwave next week if its price keeps going down. 如果價(jià)格持續(xù)下降,下個(gè)禮拜我們就買那臺(tái)微波爐。 If +, Ill / youll + 條件結(jié)果1. 結(jié)構(gòu)For example: If you study, Ill be happy. wear jeans to sc

8、hool, youll be sorry. get up late, youll be late. eat too much, youll be fat. wash your clothes yourself 有時(shí)，我們可以使用并列結(jié)構(gòu)的祈使句來表達(dá)if引導(dǎo)的條件句。如：If you set your alarm clock, you wont oversleep.如果你上鬧鐘, 你就不會(huì)睡過頭了。Set your alarm clock, and you wont oversleep. If you give him an inch, he will take a mile. 他會(huì)得寸進(jìn)尺。

9、 Give him an inch, and he will take a mile. If you dont give him some food, he will starve. 如果你不給他一點(diǎn)吃的, 他就會(huì)餓死。 Give him some food, or/else he will starve.2. 用法(1)條件狀語從句通常由連詞if引導(dǎo), 意為“如果、假如”, 主句不能用be going to表示將來, 而應(yīng)該用shall, will。e.g. If you leave now, you are never going to regret it. (錯(cuò)誤) If you lea

10、ve now, you will never regret it. (正確)(2) if “如果”, 引導(dǎo)條件狀語從句, 主句用一般將來時(shí), 從句則用一般現(xiàn)在時(shí)，如： If it rains tomorrow, I shant climb the hills.注意: 賓語從句中的if與條件狀語從句if的區(qū)別。賓語從句中的if“是否”相當(dāng)于whether, 引導(dǎo)賓語從句, 時(shí)態(tài)需根據(jù)語境確定。I dont know if it will rain tomorrow. 我不知道明天是否會(huì)下雨。在閱讀英文文章時(shí), 我們有可能看到這樣的句子：If my father will give me perm

11、ission, I shall spend a few months abroad. 如果我父親同意, 我將在國外待幾個(gè)月。If you will take the trouble to read his letter carefully,you will see what he means. 如果你肯花一些時(shí)間來認(rèn)真讀他的信，你就會(huì)明白他是什么意思了。在if-分句中用“will動(dòng)詞原形”并不單純表示將來意義，這里的will是個(gè)表示“意愿”的情態(tài)動(dòng)詞, 相當(dāng)于be willing to(愿意)。要注意這種帶“will動(dòng)詞原形”的if-分句在某些場合是不可以隨便用的, 比如我們可以說：If he

12、 gets my letter in time, hell be able to change his plans. 如果他及時(shí)收到我的信, 他就能改變他的計(jì)劃。卻不可以說成：If he will get my letter in time, hell be able to change his plans.If you would try Italian food, you would like it. 如果你愿意嘗嘗意大利食物, 你會(huì)喜歡它的。If you would reserve the seats, we would be sure of a comfortable journey.
