short,to get(back)to the point,to put it another way,to tell the truth;,动词+how/what/where/which/when/why+to do,有些动词后面跟不定式时，不定式前需要加疑问词，如how,when,why,where,whether,which等。这些动词有：know,wonder,find out,guess,discuss等。,The old man forgot how to get home after he left the shop.The leader concerned told the news reporters frankly that he did not know whom_ for the accident caused by fake wine.A.is blame B.to blame C.blames D.will blame,在“名词（代词）+be+easy(difficult,fit)+不定式”结构中，有时尽管句中主语是动作的承受者，不定式在意义上是被动的，形式上却是主动的。The book is difficult to read.The path is easy to find.,有些动词后面加不带to 的动词不定式：had better,would rather,may/might as well,cant help but,do nothing but/exceptdo anything/everything but/except 1.my sister could do nothing else but read books.当but/except前没有do时，后面则接to do sth 2.I had no choice but to go with him.注：有do 没to,没do 有to.,并不是所有的to 都是动词不定式。下面的to 是介词，以下是固定搭配。attributeto（归因于)applyto（致力于）accustomto(使习惯于)confineto(限于范围内)dedicateto（奉献）preferto（喜欢）oweto（归功于）,be accustomed to（惯于）be

pipe.,二、现在分词,现在分词的形式跟动名词一样:-ing过去分词的形式:-ed.现在分词表示“主动”、“进行”。过去分词表示“被动”、“完成”。主动语态：doing（一般式），having done（完成式）被动语态：being done（一般式）,having been done（完成式）,下列结构后面通常接ing 形式：it is no use+doing sth.it is no good+doing sth.it is no help+doing sth.It is not worth+doing sth.it 作形式主语，动名词做真正的主语。但在it is of no use 后面则用动词不定式。例如：It is of no use to cry over spilt milk.,下列结构后面通常接ing 形式:,have a hard time doing have difficulty(in)doing have trouble（in）doing have fun(in)doing there is no point(in)doing take risks(in)doing take pleasure(in)doing take pride(in)doing,后面加doing

to,cant help,三、分词独立结构,分词的逻辑主语与谓语动词主语不一致时，分词必须有自己的主语。这种带主语的分词结构叫做分词的独立结构。独立主格选择题的特点：句中两个部分各有主语，之间用逗号分开，中间没有任何连接词。,分词的独立结构例句：,Night falling,we hurried home.=When the night fell,(表时间）The train being late,we missed our plane.=Because the train was late,(表原因）Weather permitting,well have the match tomorrow.=If weather permits,(表条件）,四、悬垂分词,是一种具有独立性的分词，在句中做状语时，它的逻辑主语不必与句子主语保持一致。Regarding,Concerning,Judging from,Considering,Generally speaking,Admitting(that),Judging from the number of cars,there were not many guests in the restaurant.从汽车的数量来看，饭店里的人不多。Considering his age,he did a good job.就他的年龄而言，他做得很不错。,历年真题:All the things_,his proposal is of greater value than yours.(2009年)A.consideredB.consideringC.to
