目的、结果状语从句.ppt

目的、结果状语从句,讲解,一、目的状语从句,简介 目的状语从句：从句部分是用以补充说明主句中 谓语动词发生的目的的状语从句。目的状语从句的谓语常含有may,might,can,could,should,will,would等情态动词。引导目的状语从句常用的连词有：so that（以便），in order that（为了；以便）E.g.You must speak louder so that you can be heard by all.(该句为目的状语从句的普遍形式）,【注意】in order that与in order to的区别：in order that+从句in order to+动词原形（in order to后面加的那个不叫目的状语从句，叫目的状语）in order to“为了”,后接动词原形，做目的状语。E.g.I get up early in order to catch the early bus.in order that 为了，后接从句，做目的状语。E.g.I get up early in order that I can catch the early bus.,二、结果状语从句,简介结果状语从句常由so that或suchthat引导，掌握这两个句型，首先要了解so 和 such与其后的词的搭配规律。so和 such结果状语从句其规律由so与such的不同词性决定。such 是形容词，修饰名词或名词词组，so 是副词，只能修饰形容词或副词。so 还可与表示数量的形容词many,few,much,little连用，形成固定搭配。,such+（a/an）+形容词+名词=so+形容词+（a/an）+名词注意so many 已成固定搭配，a lot of 虽相当于 many，但 a lot of 是名词性的，只能用such搭配。因此，sothat与 suchthat之间的转换既为 so与such之间的转换。E.g.The boy is so young that he cant go to school.He is such a young boy that he cant go to school.,总结,结果状语从句的从句部分是补充说明主句中谓语动词发生的结果的，通常位于主句之后。结果状语从句中通常不用情态助动词，但must can could除外。such用在（形容词）名词之前；而so要用在形容词或副词之前，so或that有时会省略掉。,练习,根据句意，用so或such填空。1.Theboyis_youngthathecantgotoschool.2.Hetoldus_afunnystorythatwealllaughed.3.Hehas_fewbookstoreadthathehastoborrow some booksfromthelibrary.4.Itis_atallbuildingthatIcantseeitstop.,so,such,so,such,选择恰当答案1.Pleasespeakloudly_allofuscanhearyou.A.sothat B.if C.when D.although2.HelearnedalittleJapanese_hewasat middleschool.A.though B.although C.asif D.when3.Shewas_tired_shecouldnotwalkanymore.A.very,that B.such,that C.so,that D.so,as4.Iwenttoschoolinahurry_Iwouldntbe lateforclass.A.since B.sothat C.asif D.unless,A,D,C,B,Thank you!,
