原因状语从句 because since as for now that considering that seeing that 考虑到 鉴于 鉴于 由于 因为 考查重点because since as for because 直接原因 非推断 语气最强 回答whysince 通常放句首 译为 既然 as 不谈自明的原因 语气最弱 for 放句中 对前面一句话的内容的补充说明 1

出题者既考状语从句又考定语从句和状语从句的区别 还加入名词性从句这一干扰项 地点状语从句 1 ifyouaretraveling thecustomsarereallyforeigntoyourown pleasedoastheromansdo a inwhichb whatc whend where2 inpeace too theredcrossisexpectedtosendhelp

sothat inorderthat forfearthat sothat引导状语从句只能置于主句之后 inorderthat引导状语从句可放主句之前或之后 目的状语从句的谓语常含有can could may might情态动词 这也是与结果状语从句的一个区别 引导结果状语从句的连词有 sothat so that such that 结果状语放在主句之后 注意 在so that such that结构中一般成分齐全 这也是与as引导定语从句的区别 在so as such as这一结构中 as引导定语从句 在句中做成分 1 rosesneedspecialcare theycanlivethroughwinter a becauseb sothatc evend as 04全国卷i 2 i dliketoarrive20minutesearly

条件状语从句一般考查三点 1 在条件状语从句中常用一般现在时表示一般将来时 用一般过去时表过去将来时 2 if unless incase是考查重点 3 when还可表条件 这一点不可忽视 意思是 既然 考虑到 如 howcantheylearnanythingwhentheyspendalltheirsparetimewatchingtelevision 他们把所有空闲的时间都用来看电视了 还能学到什么东西呢 1 youcallmetosayyou renotcoming i llseeyouatthetheatre 2004吉林 a thoughb whetherc untild unless2 whatwouldyoudoifit tomorrow wehavetocarryiton sincewe vegoteverythingready 05全国 a rainb rainsc

what when which who where however whatever whenever whichever whoever wherever as 尽管 1 although与though可互换 都可以与yet still连用 但不能和but连用 2 however引导让步状语从句时后紧跟形容词或副词 3 while也可引导让步状语从句 这一点特容易被考生忽视 4 whatever修饰名词 无论什么 however修饰形容词 副词 无论多么 无论怎么 5 evenif eventhough 即使 与asif asthough 好像 这两组学生容易混淆 也是出题者关注的对象 平时要记准含义 1 ihavetoputitawayandfocusmyattentiononstudythisweek 04上海春 a howeverthestoryisamusingb

状语从句中从句的省略现象 08 安徽 haveyougotanyparticularplansforthecomingholiday yes i mgoingtovisitsomehomesfortheoldinthecity a ifeverb ifbusyc ifanythingd ifpossible 考查省略句 此句的意思是 你们为即将到来的假期做了特别的计划没 是的 如果有可能的话 我们将去拜访这座城市的老年之家 ifpossible是ifitispossible的省略形式 剖析 由as once when while before after till until引导的时间状语从句 由if unless whether引导的条件状语从句 由though although evenif whatever引导的让步状语从句 由as than引导的比较状语从句 由as asif
