對,
但這些動詞的形式是
should + 動詞原型
were to + 動詞原型
動詞過去式
例：
If he should come tomorrow,I would ask for his autograph
If he were to come tomorrow,I would ask for his autograph
If came tomorrow,I would ask for his autograph
這種句子也可以用倒裝形式這樣說
Should he come tomorrow,I would ask for his autograph
Were he to come tomorrow,I would ask for his autograph
至于何時用哪個,英語很靈活,對這沒有語法規(guī)定,僅是寫作風格的問題而已.
希望幫到了你,
我是加拿大人,英語母語.那為什么還要存在三種形式呢？既然一樣一種就夠了呀。像虛擬語氣現(xiàn)在和過去就只有一種啊。謝謝哈哈哈，如果語言僅有一個表達方式，一個選擇，這個世界就不會有散文，詩歌，音樂，歌唱了。。。那生活不是太枯燥了？但我們凡人不必那么緊張，在日常生活里，我們沒有必要掌握這些復雜的語法的奧妙之處。對嗎？
