A原因狀語從句because,since,as,for,now(that),considering(that),seeing(that)考慮到／鑒于鑒于／由于／因為考查重點because,since,as,forbecause—直接原因，非推斷．語氣最強．回答whysince–通常放句首．譯為“既然”as–不談自明的原因，語氣最弱．for–放句中，對前面一句話的內容的補充說明

。1.Parentsshouldtakeseriouslytheirchildren'srequestsforsunglasses____eyeprotectionisnecessaryinsunnyweather.(2004上海)A.because

B.ifC.whenD.where

A

A地點狀語從句由where.wherever引導。where指“在某個地方”，wherever指“無論哪里，在任何一個地方”，在使用時：一要注意兩者的含義區別。二要注意狀語從句和定語從句的區別。三要注意在狀語從句中不可使用介詞+which引導。出題者既考狀語從句又考定語從句和狀語從句的區別。還加入名詞性從句這一干擾項。地點狀語從句1.Ifyouaretraveling____thecustomsarereallyforeigntoyourown，pleasedoastheRomansdo.(2006天津)2.Inpeace，too，theRedCrossisexpectedtosendhelp___thereishumansuffering.A.whoever

D目的狀語從句和結果狀語從句引導目的狀語從句連詞有：incase,sothat,inorderthat,forfearthat。

sothat引導狀語從句只能置于主句之后。Inorderthat引導狀語從句可放主句之前或之后。目的狀語從句的謂語常含有can，could，may，might情態動詞。這也是與結果狀語從句的一個區別。引導結果狀語從句的連詞有：sothat，so…that，such…that.結果狀語放在主句之后。

注意：在so…that，such…that結構中一般成分齊全。這也是與as引導定語從句的區別。在so…as，such…as這一結構中，as引導定語從句，在句中做成分。1.Rosesneedspecialcare____theycanlivethroughwinter.A.because

C條件狀語從句

ifas/solongas

asfarasunlessincase（如果）suppose/supposing(that)Providing/provided(that)onconditionthatgiven(that)

條件狀語從句一般考查三點：1)在條件狀語從句中常用一般現在時表示一般將來時，用一般過去時表過去將來時。

2)if，unless，incase是考查重點。3)when還可表條件，這一點不可忽視。意思是：既然，考慮到。如：

C讓步狀語從句讓步狀語從句的連詞有：though/although“盡管”，evenif/eventhough“即使”，nomatterhow(what，when，which，who，

where)，however(whatever，whenever，whichever，whoever，

wherever),as“盡管”1)although與though可互換，都可以與yet，still連用，但不能和but連用。2)However引導讓步狀語從句時后緊跟形容詞或副詞。3)While也可引導讓步狀語從句，這一點特容易被考生忽視。4)Whatever修飾名詞，“無論什么”，however修飾形容詞、副詞，“無論多么，無論怎么”。5)evenif/eventhough(即使)與asif/asthough(好像)這兩組學生容易混淆，也是出題者關注的對象，平時要記準含義。，Ihavetoputitawayandfocusmyattentiononstudythisweek.(04上海春)A.HoweverthestoryisamusingB.NomatteramusingthestoryisC.HoweveramusingthestoryisD.Nomatterhowthestoryisamusing2.____Iacceptthatheisnotperfect，Idoactuallyliketheperson.(04江蘇)A.While
