①在复合句中，修饰某一名词或代词的从句叫作定语从句。例：唱歌的那位女士是我的老师。Thewomanthat/whoissingingismyteacher.主句定语从句主句先行词关系代词（做主语，不能省略）beinterestedin意为“对……感兴趣”，其后常接名词、代词或动词ing形式作宾语。卡伦对艺术感兴趣。Karenisinterestedinart.卡伦的哥哥对听音乐感兴趣。Karen’erestedinteresting意为“感兴趣的”，主语是人，用来说明人的感受。意为“有趣的”，既可作表语，也可作定语，主语通常是物，用来描述和形容事物的特征和性质。辨析：interested与interesting2.Asamountainclimber,Aronisusedtotakingrisks.beusedto习惯于……to其后接名词、代词或动词-ing形式作宾语。他习惯伴随着轻音乐入睡。Heisusedtofallingasleepwithlightmusic.beusedtodoing表示“习惯于做某事”beusedtodo表示“……被用来做某事”我现在习惯吃米饭。Iamusedtoeatingricenow.刀能用来切肉。Theknifecanbeusedtocutmeat.典例剖析—Didyourfatheruseto_____towork?—Yes,butnowhelikesusingpublictransportation.Heisusedto_____thebus.A.drive;takingB.driving;takingC.driving;take3.Butwhenhiswaterranout,heknewthathewouldhavetodosomethingtosavehisownlife.

①runout意为“用尽；耗尽”，是“动词＋副词”短语，不用于被动语态，以主动形式表示被动意义。辨析:runout&runoutof意思区别runoutrunoutof(某物)用完，不多了。用完(某物)。相当于不及物动词，后面不能接宾语。相当于及物动词，后面需加宾语。根据语境，用runout或runoutof的适当形式填空。(1)—Haveyougotanywater?—Yes,butit________justnow.(2)She___________timeanddidn’tfinishthelastquestion.ranoutranoutofPractice②动词不定式(短语)作目的状语tosavehisownlife在句中作状语，表示目的。动词不定式（短语）在句中作目的状语时，既可放在句首，也可放在句末，意为“为了……”。为了赶上早班车，你需要早点起床。

Tocatchtheearlybus,youneedtogetupearly.吉姆昨天去图书馆借了一些科学杂志。
