课件13张PPT。第37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。高频考向一 表时间和原因的状语从句【例1】I'll give it to Jim as soon as I ________ him tomorrow.(2016，铜仁)
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：____
【例2】 The traffic policeman took away Jim’s driver’s license ________ he broke the traffic rules of drunk driving.(2016，广东)
A．though B．till C．and D．because
解析：though意为“尽管，虽然”，引导让步状语从句；till意为“直到……为止”，引导时间状语从句；and意为“和，并且”，表示并列或顺承关系；because意为“因为”，引导原因状语从句。根据句意“交警没收了吉姆的驾照”和“他违反了酒驾的交通规则”可知二者是因果关系，应用because引导原因状语从句。
答案：____CD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。高频考向二 表条件和让步的状语从句【例3】________ the car is old，it still runs well.(2016，德阳)
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：____
【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：____CA高频考向二 表条件和让步的状语从句【例5】I don't know if Tom ________ here tomorrow.If he ________，I'll call you.(2016，南充)
A．comes；come B．will come；will come
C．comes；will come D．will come；comes
解析：考查if引导的从句的时态。前句中if意为“是否”，引导的是宾语从句，tomorrow是一般将来时的标志，所以第一空应用will come；后句中if意为“如果”，引导条件状语从句，遵循“主将从现”原则，又因主句用了一般将来时，所以从句应该用一般现在时comes。
答案：____D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。高频考向三 表目的和结果的状语从句 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。高频考向三 表目的和结果的状语从句 【例6】—How do you like the movie Kongfu Panda 3?
—It is ________exciting________I'd like to see it again.(2016，咸宁)
A．so；that B．such；that
C．enough；to D．too；to
解析：句意：——你认为《功夫熊猫3》这部电影怎么样？——它如此激动人心以至于我想要再看一遍。so＋形容词、副词＋that...＝such＋a/an＋形容词＋单数名词＋that...“如此……以至于……”；形容词、副词enough to do sth“足够……做某事”；too＋形容词、副词to do sth“太……而不能做某事”。结合句意，此处修饰形容词exciting，故用句型so...that。
答案：____A高频考向三 表目的和结果的状语从句 【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”。
