表解语法助记1．不定式的用法
2.不定式的时态和语态
3．“but＋不定式”的用法
即学即用语法填空(1)________(knck)at the dr befre yu enter my rm，please.答案：Knck　本题考查祈使句。 句意：在进我的房间之前请先敲门。 句中出现连词befre说明前后都为句子，因此用原形，为祈使句。
(2)Nthing is s easy as ________ parents t raise their expectatins f their children t high.答案：fr　本题考查介词的用法。句意：没有什么事情与父母过高地提高对孩子的期望值那么容易。此处为不定式的复合结构。注意：fr sb.t d sth.与f sb.t d sth.的区别。当用fr 时，表示其前面的形容词是修饰t d sth.；用f时，其前的形容词是修饰sb.的。故此处用fr。
(3)Gerge returned after the war，nly ________(tell)that his wife had left him.答案：t be tld　本题考查非谓语动词，“nly t d”作结果状语。句意：战后乔治回来了，结果被告诉他妻子已离他而去。 nly t d sth.表示意料之外的结果。答案：A(4)Tm tk a taxi t the airprt，nly ________(find)his plane high up in the sky.答案：t find　本题考查非谓语动词。非谓语动词作状语，表示意想不到的结果，要用动词不定式。句意：汤姆搭乘出租车到了机场，结果发现他要坐飞机已高在天空。
(5)He tld us whether________(have)a picnic was still under discussin.答案：t have　考查“特殊疑问词＋不定式”作主语的用法。whether t have a picnic作宾语从句的主语，意思是“要不要举行野餐还在讨论之中”。(6)Nwadays peple smetimes separate their waste t make it easier fr it ________(reuse)． 答案：t be reused　本题考查动词不定式的用法。句意为：当今，人们常把垃圾加以分类从而使之更容易被回收利用。在逻辑上it与reuse之间是动宾关系，所以用动词不定式的被动结构。
(7)The children all turned________(lk at)the famus actress as she entered the classrm.答案：t lk at　句意为：当那位著名的女演员走进了教室，所有的孩子都转过头去看她。turn t 表示“转向；求助”的意思。但此处turn意为“转身”，其后的不定式表目的。(8)________(be)a winner，yu need t give all yu have and try yur best.答案：T be　考查非谓语动词的用法。根据后句“你需要付出一切并尽你最大努力”可知还没有成为胜者，t be a winner为目的状语，“为了成为一名胜者”。
(9)I have a lt f readings________(cmplete)befre the end f this term.答案：t cmplete　本题考查非谓语动词的使用。句意应为：这个学期结束前，我要做很多阅读练习。由于时间状语befre the end f this term表达未来的时间，所以空格处使用动词不定式表示将来，充当readings的定语。
(10)His first bk________(publish)next mnth is based n a true stry. 答案：t be published　考查非谓语动词。此处是非谓语动词作后置定语，由时间状语next mnth可知所填非谓语动词表示将来的动作，用动词不定式，其逻辑主语是所修饰的名词bk，不定式与逻辑主语是被动关系，故用不定式的被动式。
(11)He was astnished________(find)that his sn was still asleep when it's time fr wrk.答案：t find　句意：他吃惊地发现他儿子在上班时间睡觉。考查非谓语动词。be astnished 后应该跟动词不定式作状语。(12)—It's n use having ideas nly.—Dn't wrry.Peter can shw yu ________t turn an idea int an act.答案：hw　句意：——光有主意没用。——不用担心，皮特可以教你怎样把主意变为行动。考查连接词的用法。hw表示“怎样”，强调方式。
