【正文】 on time.It is very kind of you to help us.注意：（1）其他系動詞如look, appear等也可用于此句型。試比較： It is to negate my own idea to believe him.（錯） To believe him is to negate my own idea .（對） （3）It is+ adj. of / for sb. to do sth. 結構中，當不定式的邏輯主語和前面的形容詞可以構成系表結構時，用of, 否則用 for. 作賓語（1） 動詞+不定式。如：I don’t know what to do next/ how to do it next.I can’t decide when to go there.注意：不定式短語作賓語時，如果還帶有賓語補足語，往往把不定式短語放在賓語補足語之后，用it 作形式賓語。如：He warned me to be careful.I want you to speak to Tom.What makes you think so?（不帶to的不定式） 注：可以用動詞不定式做賓補的動詞有：ask, tell, order ,want ,get, would like, like, advise, invite, allow, help, wish,warn, expect, prefer, encourage（2） 表見解、看法的動詞結構可為：動詞+賓語+ to be 的不定式結構。如：We didn’t expect there to be so many people 。如：We regard Tom as our best teacher. 我們認為湯姆是我們最好的老師。（2）在動詞feel （一感），hear, listen to（二聽），have, let, make（三讓），notice, see, watch, observe, look at（五看）(即：吾看三室兩廳一感覺)等后面的補足語中，不定式不帶to，但變?yōu)楸粍诱Z態(tài)后，必須帶to。不定式通常要放在這些被修飾的詞后。如： Do you have anything else to say? ，則要保留不定時短語中的副詞或介詞。（1） 做目的狀語，to, only to （僅僅為了）, in order to, so as to, so(such)….as to…（如此）如：He ran so fast as to catch the first bus. 他飛快地跑以便趕上第一班車。如：He hurried to the post office only to find it was closed.He searched the room only to find nothing.（3） 做原因狀語。如：To turn to the left , you could find a post office. 作表語不定式可放在be動詞后面，構成表語。 ，表語不能用Ving形式，可用不定式。如：To tell you the truth, I don’t agree with you.To make matters worse, it began to rain.二、 不定式的時態(tài)和語態(tài) 不定式的時態(tài)（1） 現(xiàn)在時：有時與謂語動詞表示的動作同時發(fā)生，有時發(fā)生在謂語動詞的動作之后。如：I’m sorry to have given you so much trouble.He seems to have caught a cold.（3） 進行時：表示動作正在進行，與謂語動詞表示的動作同時發(fā)生。如：She is known to have been working on the problem for many years. 不定式的語態(tài)當不定式的邏輯主語是其動作的承受者時，就用被動式。如：I saw him dance. He was seen to dance. The boss made them work the whole night.They were made to work the whole night. 使役動詞 let, have, make. 由 and, or 和 than 連接的兩個不定式，第二個 to 可以省去。試比較： He wants to do nothing but go out. He wants to believe anything but to take the medicine. 通常在discover, imagine, suppose, think, understand 等詞后，可以省去 to be .如：He is supposed (to be) nice. 他應該是個好人。如：Tell him not to shut the window.
