大家给我做了这些题以后在告诉我一下为什么要那么写好吗
1.he would enjoy this if he______(be)present.
were 如果他在的话一定会喜欢这个的.这个句子的考点是虚拟语气.if条件从句中与现在事实相反,动词用did/were.
2.she can do better if she______(try)这个是最不明白的.
tried. 原因同上.
3.if you play with matches,you________(burn)your fingers.
would/may/might burn 如果你玩火柴,就可能会烫着手指.表示可能性.
4.if you broke this window,you_______(have to)pay for if.
would have to 如果你打破了窗户,就必须赔偿.break动作发生在过去.if从句中如果是过去时,主句则用过去将来时;如果从句是现在时,主句则用一般将来时.
5.if you______(lose)your way,you would have to asd a policeman.
lost 同上.如果你迷路了,可以问警察.
6.if you________(not apologize),he will never speak to you again.
don't apologize 同上.如果你不道歉,他就不会再和你说话了.
7.if he_____(be)clever,he would not have any difficulty.
was 同4 这里if不表示虚拟,而表示陈述.
8.if i were you,i_______(not be)so confident.
wouldn't be 虚拟语气.如果与现在事实相反,if从句动词用did/were, 主语动词用would/should/could/might do.
