第三节　状语从句【考点精析】项目连词例句注意事项时间状语从句when, while, as, before，after, since，until, the moment等When I was walking along the street, I met a friend of mine. I will tell him the news the moment he comes.要注意时态一致，一般情况下，在时间状语从句中，表示将来的动作用一般现在时(不可用将来时)地点状语从句where, whereverWhere there is a will, there is a way.We are always welcome wherever we go.注意不要和where引导的定语从句混淆，若是定语从句，where前必然有先行词条件状语从句if, unless, as/so long as, on condition that, in case等You should go to school unless you are seriously ill. He will certainly pass the exam next term if he works hard at his lessons.条件状语从句和时间状语从句一样，当主句是将来时的时候，从句要用一般现在时原因状语从句because，since，as，now (that)He didn’t go to school because he was ill. As he is a League member, he takes the lead in everything in his class.①because语气最强，回答why提出的问题；since次之；as最弱；②as引导的从句往往放在主句前面，for后面的并列分句往往表示一种附带的解释或说明让步状语从句although, though, as, even if/though，whatever, however, whoever, no matter what/who/howAlthough he is a child, he knows a lot.Tired as/though I was, I went on with my work. I will go and attend the meeting however busy I am.①当用though或 although引导从句时，后面的主句不能有but；②as引导的让步状语从句必须把表语、状语或动词原形提前结果状语从句so ...that ..., such ...that ..., so thatHe runs so fast that no one can catch up with him.It was such an interesting novel that I read it three times. I got up late so that I missed the early bus. 在so ... that ... 和such ...that ... 结构中，so为副词，后面跟形容词、副词或分词，而such为限定词，后面只能跟名词或名词性短语方式状语从句as, just as, as if, as thoughWe should work and study as he did.They talked as if they had been friends for years.as if, as though在方式状语从句中多指非真实的或可能性较小的情况，常用虚拟语气比较状语从句as ... as ..., not so ...as, 比较级＋thanHe works as hard as everyone else (does) in the class.He is taller than any other student in our school.可以用比较句型表示在一定范围内的最高级含义：比较级＋than＋any other＋单数可数名词目的状语从句so that, in order that, for fear that, in case (that)She studies hard so that/in order that she can enter a key university.Take an umbrella with you in case it should rain.从句中常用may, might, can, could, should等情态动词　单句语法填空1.(2022·福州四校联盟模拟)Tibor Navracsics, the European Union’s top culture official, told The Associated Press that “we are so used to our outstanding cultural heritage that we tend to forget that it needs restoring from time to time.”2.(2022·汕头一模)As/When the sky grows dark once more, you return to your bed and go to sleep, to be awakened early the next morning happily by the sight of a deep desert valley just outside Lanzhou.3.(2022·衡水中学期末)Last year I met a couple of young students I’d known before I travelled to Dali, and we agreed to cycle along the lake in a small town outside of Dali.【规律方法】1.牢记固定句式结构，确定连词。【典例】　—How long do you think it is ______ he arrived here?—No more than half a year，I believe.解析　“It is＋时间段＋since sb did sth”意为“自从某人做某事到现在有多久了”，为固定句型。答案　since2.根据主从句的逻辑关系确定状语从句的连词。如果主从句是因果关系，则要考虑用because，as，since；如果主从句有时间先后之分，则要考虑用时间状语从句的连词；如果从句为主句的条件， 则要考虑用if；如果从句表示让步， 则要考虑用although，though，while。【典例】　In addition，forests have been decreasing rapidly ________ too many trees have been cut down.解析　考查状语从句。根据上下文语境看，此空应该填表原因的连词because/as，引导原因状语从句。答案　because/as
