while後面是要用動詞ing形式嗎 小煩惱 1級 2015-04-10 回答

be動詞後面的動詞形式有三種可能: -ing:現在進行時, i‘m trying to give you the right answer。 -ed:被動語態, i’m told that you don‘t know her。 to do: 1。表示按計劃或安排要做的事。例如: when are you to leave for home?你什麼時候回家? they said goodbye, little knowing that they were never to meet again。他們告了別,不知道以後再也不會見面了。 2。表示“應該”,相當於should, ought to。例如: you are to report to the police。你應該報警。 3。表示“必須”,相當於must, have to。例如: the letter is to be handed to him in person。這封信必須親手交給他。 4。表示“想,打算”,相當於intend, want。例如: if we are to be there before ten, we’ll have to go now。如果我們要在十點前到,我們現在就得走。 5。用於第一人稱疑問句,表示徵求對方意見。例如: am i to go on with the work?要我繼續完成這項工作嗎? what are we to do next?我們下一步該怎麼辦? 6。用於否定句,表示“禁止”,相當於mustn’t。例如: you are not to smoke in the reading-room。你不可以在閱覽室裡吸菸。 7。表示“可以,可能”,相當於may, can。例如: the news is to be found in the evening paper。這條訊息可以在晚報上見到。 8。were to do sth。用於if或even if / even though從句中,表示對未來的假設。例如: if i were to tell you that i killed him, would you believe me?要是我告訴你是我殺了他,你會相信嗎? 9。be to blame(該受責備,對某壞事應負責任)與be to let(待出租)兩種結構中,用不定式的主動形式表示被動含義。例如: which driver is to blame for the accident?這事故是哪個司機的責任? this house is to let。這房子要出租。
