由于 因為 考查重點because since as for because 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(nèi)容的補充說明 1 Parentsshouldtakeseriouslytheirchildren srequestsforsunglasses

A 地點狀語從句由where wherever引導(dǎo) 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(qū)別 二要注意狀語從句和定語從句的區(qū)別 三要注意在狀語從句中不可使用介詞 which引導(dǎo) 出題者既考狀語從句又考定語從句和狀語從句的區(qū)別 還加入名詞性從句這一干擾項 地點狀語從句 1

forfearthat sothat引導(dǎo)狀語從句只能置于主句之后 Inorderthat引導(dǎo)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(tài)動詞 這也是與結(jié)果狀語從句的一個區(qū)別 引導(dǎo)結(jié)果狀語從句的連詞有 sothat so that such that 結(jié)果狀語放在主句之后 注意 在so that such that結(jié)構(gòu)中一般成分齊全 這也是與as引導(dǎo)定語從句的區(qū)別 在so as such as這一結(jié)構(gòu)中 as引導(dǎo)定語從句 在句中做成分 1 Rosesneedspecialcare theycanlivethroughwinter A becauseB sothatC evenD as 04全國卷I

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(xiàn)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 Howcantheylearnanythingwhentheyspendalltheirsparetimewatchingtelevision 他們把所有空閑的時間都用來看電視了 還能學(xué)到什么東西呢 1 youcallmetosayyou renotcoming I llseeyouatthetheatre 2004吉林 A ThoughB WhetherC UntilD Unless2

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(dǎo)讓步狀語從句時后緊跟形容詞或副詞 3 While也可引導(dǎo)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(xué)生容易混淆 也是出題者關(guān)注的對象 平時要記準含義 1 Ihavetoputitawayandfocusmyattentiononstudythisweek 04上海春 A HoweverthestoryisamusingB NomatteramusingthestoryisC HoweveramusingthestoryisD
