课件12张PPT。四川省英语第34讲 状语从句中考主要考查时间、原因、条件、比较、结果和让步状语从句的基本用法，尤其应注意当主句为一般将来时时，时间和条件状语从句用一般现在时表将来。高频考向一 表时间和原因的状语从句
①时间状语从句表示主句动作发生的时间。引导这种从句的连词有when，before，after，as，while，till，until，since等；起连接作用的短语有as soon as等。在时间状语从句中，当主句是一般将来时或祈使句表示将来的意义时，时间状语从句用一般现在时表将来。
如：I'll let you know as soon as she comes.她一来，我就会让你知道。
Jane didn't go to bed until she finished her homework.简直到完成作业后才睡觉。②原因状语从句用来说明原因。引导这种从句的词有连词because，since，as等。这三个词的语气由because到as逐渐减弱；because回答why提出的问题。
如：I won't go with you because I am busy doing my homework now.我不会跟你去，因为现在我正忙着做作业。
As the weather was fine，we decided to play football.天气很好，我们决定去踢足球。【例1】I'll give it to Jim as soon as I ________ him tomorrow.(2015，崇左)
A．saw B．will see C．see D．have seen
解析：as soon as表示“一……就……”，其主句用将来时态，从句要用一般现在时态。
答案：__C__
【例2】 Mark isn't coming to the concert ________ he has got too much work to do.
A．so B．until C．although D．because
解析：“太多工作要做”是“没有来音乐会”的原因。
答案：__D__高频考向二 表条件和让步的状语从句
①条件状语从句常用连词if，unless等引导。if，unless引导的条件状语从句中，当主句是一般将来时或祈使句表示将来的意义时，时间状语从句用一般现在时表将来。
如：Will you come if he comes here？如果他来，你会来吗？
If it rains tomorrow，we'll stay at home.如果明天下雨，我们会待在家里。
②让步状语从句用从属连词though，although引导。注意though/although与but在句中不能同时出现。
如：We had to go on walking though we were really tired.尽管很累了，但是我们不得不继续走。
Although he is not rich，he lives happily.尽管他不富有，但是他生活得很幸福。【例3】—You bought the car about ten years ago?
—Yes.________ it's old，it still runs well.
A．Because B．Since
C．Although D．But
解析：考查让步状语从句。句意为“尽管旧了，但它运转很好”。because“因为”，since“既然”，although“尽管”，but“但是”。
答案：__C__
【例4】 I enjoy fresh air so I always let the window open ________ it is really cold.
A．unless B．when C．if D．since
解析：句意为“我喜欢新鲜空气，因此我总是让窗户开着，除非真的很冷”。故unless“除非”符合题意。
答案：__A__【例5】—Mary，could you tell me if your mother ________ our school sports meeting tomorrow？(2015，滨州)
—I think she will come to school if she ________ free.
A．will take part in；will be B．takes part in；is
C．will take part in；is D．takes part in；will be
解析：考查if引导的宾语从句及条件状语从句的用法。问句是由if引导的宾语从句，时间状语为 tomorrow，故用一般将来时；答语是由if引导的条件状语从句，主句用将来时，从句用一般现在时。
答案：__C__高频考向三 表目的和结果的状语从句
①目的状语从句表示主句的动作发生的目的，这种从句用连词so that，in order that等引导。so that或in order that引导的目的状语从句中常常要用情态动词may，might，can，could，will，would或should等。
如：Please speak loudly so that everyone can hear you.请大声说，以便每个人听见你说的话。
He got up very early this morning in order that he could catch the first bus.为了能赶上第一班公交车，他早上起得很早。②结果状语从句表示主句的动作所引起的结果，这种从句由such...that，so...that，so that等引导。such修饰名词；而so修饰形容词或副词。
如：The film isn't so interesting that nobody likes it.这部电影不是那么有趣，没人喜欢它。
It was such a cold day that nobody wanted to go out.天气那么冷，没人想出去。
注：so...that...句型的否定形式可用简单句too...to...或not...enough to代替。
如：He is so young that he can't go to school.
＝He is too young to go to school.
＝He is not old enough to go to school.他太小了，不能去上学。【例6】—You study ________ hard ________ you're sure to pass the exam.(2015，福州)
—Thank you for saying so.
A．enough；to B．as；as
C．so；that
解析：考查so...that的用法。enough...to“足够做……”；as...as...“和……一样”；so...that...“如此……以至于……”。句意为“你学习如此努力以至于你肯定能通过考试。”“谢谢你这么说。”
答案：__C__【例7】Mr.Green speaks very loudly ________ all the people can hear him clearly.(2015，绥化)
A．when B．so that C．because
解析：when“当……的时候”；so that“为了，目的是”；because“因为”。由语境可知句意为“格林先生讲得很大声是为了让所有的人都能清楚地听见”。
