1、精選優質文檔-傾情為你奉上初二英語動詞不定式用法小結動詞不定式是動詞的一種特殊形式， 它沒有人稱和數的變化，在句子中不能做謂語；它由 “to+動詞原形”構成，其否定形式是“not to+ 動詞原形”. 在句子中可作主語、表語、賓語、賓語補足語、定語和狀語等句子成分。為使同學們更好地掌握其用法，現總結如下：一、動詞不定式作主語動詞不定式作主語，例如 To think of the animals in danger is sad .為避免句子的頭重腳輕，常用it作為形式主語，而真正的主語動詞不定式后置，如It is sad to think of the animals in danger .

2、常用句型:It +be+adj./n to do sth./It takes sb. some time to do sth.二、動詞不定式作賓語一些動詞，如want, decide, hope, ask, agree, choose, learn, plan, need, teach, prepare,等，常接動詞不定式作賓語。 應注意有些動詞后面可接不定式作賓語，也可接動名詞作賓語，但所表達的意義不同。常見的有：（1）stop to do sth.停下來去做另一件事；stop doing sth. .停止正在做的事（2）try to do sth. 盡力做某事；try doing sth.

3、嘗試做某事（3）remember/forget to do sth.記住忘記去做某事；remember/forget doing sth. 記得忘記做過某事。下列動詞（enjoy finish keep mind practice spend advise suggest allow）后面不能用不定式，用動名詞作賓語三、動詞不定式作賓語補足語有些動詞，如tell, ask, want, invite, teach, like, call等可接帶to的動詞不定式作賓語補足語，構成tell/ask/want /call/invite sb. to do sth.結構。而表示使役動詞和感官動詞后面的

4、賓語補足語時應省去to，（在被動語態中應加上to）。這些動詞可歸納為“一感(feel)，二聽(listen to, hear)，三讓(let, make, have,，四看(look at, see, watch, notice)，半幫助(help)(即在動詞help后面作賓語補足語時，to可有可無)”。 四、動詞不定式作狀語動詞不定式作狀語主要用來修飾動詞，表示目的they did lots of work to save the candas等。，表結果，常用結構有too + adj./adv. + to do sth. adj./adv.enough + to do sth，表原因be

5、+形容詞+ to do sth 如 I am surprised to hear the news.為了強調目的，有時可以把動詞不定式放在句首，或在不定式前加in order或so as to。 五、動詞不定式作后置定語時，與被修飾的名詞邏輯上有動賓關系。如果動詞不定式是不及物動詞時，則要帶上與之搭配的介詞，構成及物動詞短語。動詞不定式作后置定語常用于“have/has 某事to do”（some words to say, nothing to do,enough place to live）“Its time to do sth.”等結構中。六、特殊疑問詞+不定式 特殊疑問詞what wh

6、en why how where 等可以和不定式連用在句子做各種成分。如How to use compurers is a problem. I cant decide when to do it .動詞不定式專項訓練題：一、單項選擇。1. _ is difficult to work out the maths problem.A. ThisB. ThatC. ItD. Its2.
