if only虚拟语气的三种时态是什么?
作者&投稿:暨灵 (若有异议请与网页底部的电邮联系)
1、表示与将来情况不同:if only+ 从句主语+would(could, might)+动词原形
eg:If only she would try again.
我希望她能再试一次
2、表示与现在情况不同:if only+从句主语+动词过去式
eg:If only I wasn’t going to London.
我希望我没去过伦敦.
3、表达与过去情况不同:if only+从句主语+would/could have/had+过去分词
eg:If only you had come to my birthday party.
你要是来了我的生日晚会就好了。
if,whether这两个连接词均含“是否”之意。区别:
1、if作“是否”解时,多用于口语,引出宾语从句,不能直接跟or not连用。whether多用于书面语中,可与or或or not连用,除引出宾语从句外,还可引出主语从句、表语从句、同位语从句或与不定式连用。
2、if从句可以表示希望; 而whether从句单纯表示事实。
3、if不能用在介词之后的间接疑问句中; 而whether可以。
