地点方式原因目的状语从句复习必考知识点 状语从句修饰主句中的动词,形容词,副词等,在复合句中作状语.引导状语从句的关联词是从属连词.状语从句用陈述句语序,一般位于复合句的句首或句末。当从句在句 首时,从句后常用逗号和主句相隔。状语从句根据其在句中的不同作用分别表示时间,地点,原因,目的,结果,条件,比较,让步,行为方式等。 1.地点状语从句 地点状语从句通常由where, wherever 引导。例如： Where I live there are plenty of trees. 我住的地方树很多。 Wherever I am I will be thinking of you. 不管我在哪里我都会想到你。 2.方式状语从句 方式状语从句通常由as, as if, as though引导。 （1）as从句带有比喻的含义，意思是"正如…"，"就像"，多用于正式文体。例如： Always do to the others as you would be done by. 你希望人家怎样待你，你就要怎样待人。 （2）as if, as though引出的状语从句谓语多用虚拟语气，表示与事实相反，有时也用陈述语气，表示所说情况是事实或实现的可能性较大。汉译常作"仿佛……似的"，"好像……似的"。例如： They completely ignore these facts as if （as though） they never existed. 他们完全忽略了这些事实，就仿佛它不存在似的。（与事实相反，谓语用虚拟语气。） He looks as if （as though） he had been hit by lighting.他那样子就像被雷击了似的。（与事实相反，谓语用虚拟语气。 ） It looks as if the weather may pick up very soon. 看来天气很快就会好起来。（实现的可能性较大，谓语用陈述语气。） 说明：as if / as though也可以引导一个分词短语、不定式短语或无动词短语。例如： He star ed at me as if seeing me for first time. 他目不转睛地看着我，就像第一次看见我似的。 He cleared his throat as if to say something. 他清了清嗓子，像要说什么似的。 The waves dashed on the rocks as if in anger. 波涛冲击着岩石，好像很愤怒 3.原因状语从句 比较be cause, since, as和for： （1）beca use语势最强，用来说明人所不知的原因，回答why提出的问题。当原因是显而易见的或已为人们所知，就用as或 since。例如： I didn't go, because I was afraid. 我不去是因为我怕。 Since /As the weather is so bad, we have to delay our journey. 天气那么糟，旅行推迟了。 （2）由because引导的从句如果放在句末，且前面有逗号，则可以用for来代替。但如果不是说明直接原因，而是多种情况加以推断，就只能用for。例如： He is absent today, because / for he is ill. 他今天缺席，因为他病了。 He must be ill, for he is absent today. 他一定病了，所以今天缺席。 4.目的状语从句 表示目的状语的从句可以由that, so that, in order that, for fear that, in case等词引导。例如： You must speak louder so that /in order that you can be heard by all. 你必须大点声，别人就能听见了。 He wrote the name down for fear that（lest） he should forget it. 他写下了这个名字以免以后忘记。 Better take more clothes in case the weather is cold. 最好多穿 点衣服，以防天发冷。 题1： — I can’t find Mr. Smith .Where did you meet him this morning? — It was in the hotel ___ he stayed. A. that B. where C. the one D. which 题2： Here ! A. the bus comes B. the bus is coming C. comes the bus D. is coming the bus 题3： On the National Day, up into the air______. Then the crowd cheered up.

A. he has done as I asked B. he has done l ike I ask C. has he done as I asked D. has he done like I asked 题1： B 详解：________ he stayed是定语从句，其先行词为the hotel。从句缺少地点状语，所以选where引导定语从句。在这个题中，in the hotel是被强调部分，后接一个定语从句修饰the hotel，定语从句之后是that引导的强调句型部分。为了避免重复，在回答的时候把强调句“that+＋原句其它部分”都省去。把答句补充完整应为It was in the hotel where he stayed that I met him this morning. 题2： C 详解：here位于句首时，如果句子的主语为名词，句子要全部倒装而且要用一般现在时或一般过去时。Here comes the bus.= The bus is coming. 题3： C 详解：以out副词开头的句子且主语是名词的 句子通常用全部倒装语序而且时态要和后面的句子一致，用一般过去时，所以选C。 题4： B 详解：当not until从句放在句首时，主句要部分倒装。 题5： C 详解：否定短语not once位于句首，句子要部分倒装，排除A、B；as是从属连词，引导状语从句，而like是介词，不能引导状语从句，所以选C。
