He prided himself on having never been beaten in class. 如： (2)被動語態(tài) I shall never forget seeing the Great Wall for the firsttime. 如：There are still many things to t ake care of (to be taken care of).但有時兩種形式表達(dá)的意思不同，如：These is nothing to do now.( We have nothing to do now.) There is nothing to be done now.(We can do nothing now.) s birthday party.（不定式作主語） ①一般式：動詞不定式一般式表示的動作發(fā)生在謂語動詞之后，有時表示同時發(fā)生。如：①When we shall leave…③…h(huán)ow I 七、動詞不定式、動名詞的其它用法 但在下列結(jié)構(gòu)中，too…to并非是“太……而不能……”之意。 The speed is high enough for us to catch up with thefirst liner. ①so…as to。 ②I was surprised to see that a threeyearold baby could write so well. ②Henry has decided to go to the hospital to be examinedby the doctor. You may depend on them to be there early. ①We all believe John(to be)honest. 五、不定式作補(bǔ)足語 ⒉動名詞作定語 (3)與被修飾詞之間有動賓關(guān)系，同時與句中其它詞之間又有邏輯上的主謂關(guān)系時，盡管有被動含義，卻仍 用主動語態(tài)（例③）；如只有動賓關(guān)系，而無邏輯上的主謂關(guān)系，則需用被動語態(tài)（例②）。 (1)表示將來的動作（例①）。 ②My chief purpose is to point out the difficulties ofthe matter. ll go on fighting so long as there is oppression inthe world. go on doing 繼續(xù)不停地做某事，指同一動作的繼續(xù) doing 試著做某事 I remember writing him a letter a year ago. 如： simportant for you to keep fit. s＋形容詞＋doing s no good reading in dim light. 如： It seemed impossible to save money. s our duty to take good care of the old.
