只學(xué)到被動(dòng)語(yǔ)態(tài)的話,這些時(shí)態(tài)就夠了.按照時(shí)態(tài)要求有的句子可能有點(diǎn)奇怪,或者語(yǔ)境下不常用

I ate an apple yesterday.（主動(dòng)語(yǔ)態(tài)）
An apple was eaten by me yesterday. （ 被動(dòng)語(yǔ)態(tài)）

將來(lái)進(jìn)行時(shí)（明天這時(shí)我正在吃蘋(píng)果）：現(xiàn)進(jìn)和情態(tài)呢？說(shuō)完給你分情態(tài)動(dòng)詞：must(必須)I must eat an apple.（主動(dòng)）An apple must be eaten .(被動(dòng))have to （不得不）I have to eat an apple.（主動(dòng)）An apple has to be eaten .(被動(dòng))should(應(yīng)該)I should eat an apple.（主動(dòng)）An apple should be eaten .(被動(dòng))ought（應(yīng)該）I ought eat an apple.（主動(dòng)）An apple ought be eaten .(被動(dòng))need（需要）I need eat an apple.（主動(dòng)）An apple need be eaten .(被動(dòng))或者An apple needseating.或者An apple needs to be eaten.need上面的第一個(gè)句子是作為情態(tài)動(dòng)詞使用，后面兩個(gè)是作為使役動(dòng)詞使用的。
