Tokeepsmiling

It’simportanttolookupthenewwordsinthedictionary

whenyoustudyEnglish.1.單個不定式作主語時,謂語動詞用單數。若不定式太長,往往用it作形式主語,不定式后置。動詞不定式作主語

2.下列句型中常用不定式作主語：①It's

ourduty

totakegoodcareoftheold.照顧好老人是我們的責任。②Howlongdidit

takeyoutofinishthework?你花了多長時間來完成這項工作？③Itis

difficultforustofinishwritingthecompositioninanhour.我們難以在一小時內完成這篇作文。④Itisverykindofyou

tohelpus.你來幫助我們真是太好了。⑤Itseemsimpossible

tosavemoney.省錢似乎是不可能的。①It+be+n.+todosth.②Ittakessb.+sometime+todosth.③It+be+adj.(important/necessary/easy...)+forsb.todosth.④It+be+adj.(careless/clever/kind/stupid...)+ofsb.+todosth.

⑤Itseems(appears)＋adj.＋todo注意：動詞不定式與疑問詞how,what,when,where,which等連用構成不定式短語，也可作主語。①How

tousethecomputeristhequestion．如何使用計算機是個問題。②Where

togohasnotbeendecided．去哪兒還沒有定下來。動詞-ing形式更接近于名詞，所表示的動作比較抽象，或者是習慣性的；而不定式多表示比較具體的動作，特別是將來的動作。Paintingishishobby.繪畫是他的愛好。(抽象)Tofinishthetaskwilltakealongtime.要完成這項任務將要花費很長時間。(具體)動詞-ing形式和不定式作主語的區(qū)別用動詞-ing形式或不定式作主語時，要注意主語和表語的一致。即當表語是動詞-ing形式時，主語也要用動詞-ing形式；當表語是不定式時，主語也要用不定式。如：

Seeingisbelieving.=Toseeistobelieve.

眼見為實。Focuson基本用法to-infinitiveaspredicatives(不定式作表語)動詞不定式用作表語時放在系動詞（be動詞）之后，有時也放在seem,appear,sound,remain等其他少數連系動詞后。①Myjobis

somefreshwater.她所能做的就是回家。我要做的事就是弄些淡水來?！攧釉~不定式用作表語時，其中的to原則上是不能省略的,但是當主語部分有動詞do(did/do/does)的某種形式時，用作表語的不定式可以省略to.※當動詞不定式作主語和表語時，可以有被動形式。

①

tobecelebratednextFriday.

這個節(jié)日將于下星期五慶祝。
