Module2NoDrugsGrammar動詞不定式作狀語動詞不定式在句中作狀語,主要用來修飾動詞和形容詞,也可用來修飾副詞。在句中,不定式可作目的狀語、結(jié)果狀語、原因狀語、條件狀語等。本單元主要講解不定式用作目的狀語和結(jié)果狀語的情況。動詞不定式作目的狀語不定式作目的狀語,意為“為了……;以便于……”,常用todo,inordertodo,soastodo,so/such...astodo等結(jié)構(gòu)。如:Theteacherexplainedthesentenceclearlytobeunderstood.Hepromisedtomakealleffortssoastohelpus.注意:不定式作目的狀語時,其動作通常遲于謂語動詞的動作。如:

Isaidthattoencouragehim.2.作目的狀語的不定式之前,常常加上inorder或soas,以突出或強(qiáng)調(diào)目的的含義。如:

Iamworkinghardinordertogetabetterresult.3.如用于表示否定,inorder或soas不能省略,用inordernottodo或soasnottodo形式。如:Iwalkedquietlysoasnottodisturbthebaby.4.不定式作目的狀語可轉(zhuǎn)換為sothat/inorderthat或so...that...引導(dǎo)的目的狀語從句。如:Heworkedveryhardtopasstheexam.→Heworkedsohardthathecouldpasstheexam.→Heworkedhardsothat/inorderthathecouldpasstheexam.動詞不定式作結(jié)果狀語不定式作結(jié)果狀語時,一般出現(xiàn)在被修飾動詞之前,常用于以下結(jié)構(gòu):1.too...to...意為"太……以至不……"。如:Theboxistooheavyformetocarry.2.“not+形容詞/副詞+enoughtodo”意為"不夠……而不能……"。如:Wearenotoldenoughtovoteandtobevoted.3.onlytodo表示意料之外的事情發(fā)生。如:Hewentbackhomehappilyonlytofindhishousehadbeenbrokeninto.4.so/such...asto意為“如此……以至于……”。如:Sheissoproudastolookdownuponothers.注意:too...to...中too后跟的是pleased,glad,anxious,willing,ready等形容詞時,不表示否定的概念,而是意為“很、非?！?。如:Themotherwastooanxioustoseeherson.Thegirlwastooreadytocry.Completethesesentences,
