幻灯片 4状语从句(2)
一、让步状语从句
1．用when 和while引导让步状语从句。
不要认为when和while只引导时间状语从句，其实它们也可引导让步状语从句，意思是“尽管”或“虽然”。
She stopped when she ought to have continued.
尽管她应该继续下去，她却停住了。
While I understand what you say, I can't agree with you.
虽然我理解你的意思，但我还是不同意。
----
幻灯片 52．用whether…or…引导的让步状语从句。
I'll do it whether you like it or not.
不管你是否喜欢，我都要做。
Whether we help him or not, he will fail.
不论我们帮助他与否， 他都将失败。
----
幻灯片 63．用whatever, whoever, however, whenever, wherever 等引导的让步状语从句。
(1)均可引导让步状语从句，意为“无论……”
Whatever you say, I believe you.
无论你说什么，我都相信你。
Whoever telephones, tell them I'm out.
不管是谁打电话，都说我出去了。
Whenever you come, you are welcome.
无论你什么时候来，都是受欢迎的。
Wherever he goes, I'll go.
不管他去哪里，我也去。
----
幻灯片 7(2)引导让步状语从句时，通常可换成no matter…
No matter what you say, I believe you.
无论你说什么，我都相信你。
No matter when you come, you are welcome.
你什么时候来，我们都欢迎。
No matter how much he eats, he never gets fat.
无论他吃多少， 他都不发胖。
----
幻灯片 8(3)注意however用于以下两类句型结构：
① however＋主语＋谓语
However you travel, it'll take you at least three days.
不管你怎么走，至少要3天。
However you come, be sure to come early.
不管你怎么来，一定要早来。
②however＋形容词或副词＋主语＋谓语
However cold it is, she always goes swimming.
不管天多冷，她都会去游泳。
----
幻灯片 9有时该结构中的主语和谓语可以有所省略：
He was of some help, however small.
他总能帮些忙，不管多小的忙。
I refuse, however favorable the condition.
不管条件多好，我都不接受。
(4)有时从句谓语可用情态动词
I'll find him, wherever he is (may be).
无论他在哪里，我都要找到他。
Keep calm, whatever happens (may happen).
无论发生什么事都要保持冷静。
----
幻灯片 10(5)whenever有时可引导时间状语从句，wherever 有时可引导地点状语从句
Whenever we see him we speak to him.
每次见到他，我们都和他说话。
They teach wherever their pupils are working.
学生在哪里工作，教师就在哪里上课。
----
幻灯片 114．让步状语从句与倒装
引导倒装的让步状语从句通常用as和though，但是不能用although。
Poor though I am, I can afford it.
我虽穷，但这东西还是买得起的。
Much as I like Paris, I couldn't live there.
尽管我喜欢巴黎，但我不能住在那里。
注意：as可以在以上这样的倒装结构中引出让步状语，但若不倒装，则不能用as，而与之相反，although在不倒装的结构中可引导让步状语，但在倒装的结构中却不可以用。
----
幻灯片 12二、原因状语从句(四大点)
1．关于not…because…结构
该结构中的否定词有时否定主句，有时否定从句，一般要根据句子的意思作出正确或合乎逻辑的理解。若not否定主句，最好在because之前用逗号，否则会引起歧义，如下句在没有特定上下文时就有两种解释：
I didn't go because I was afraid.
我没有去是因为怕。/ 我不是因为怕才去。
----
幻灯片 13不过若because之前有just修饰，一般认为not 是否定从句的。
You shouldn't get angry just because some people speak ill of you.
你不要因为有人说你坏话而生气。
----
幻灯片 142．because 习惯上不与 so 连用
汉语习惯上说“因为……所以……”，但英语习惯上却不能将so与because连用：
因为下雨，所以我们待在家里。
正：Because it was raining, we stayed at home. / It was raining, so we stayed at home.
误：Because it was raining, so we stayed at home.
----
幻灯片 153．because 从句与 because of 短语的转换
because引导的原因状语从句有时可与because of 短语转换。
He can't come because he is ill. / He can't come because of his illness.
他因病不能来。
I said nothing about it because his wife was there. / I said nothing about it because of his wife's being there.
因为他妻子在那儿，我对此事只字未提。
----
幻灯片 16三、结果状语从句
1．so…that…与 such…that…的用法比较
从用法上看，so后应接形容词或副词，而such后接名词。但有时“so＋形容词”后还可接一个名词，且这个名词总是带不定冠词的单数可数名词(不能是复数名词或不可数名词)。
正：He is so clever a child that we all like him.
这小孩很聪明，我们都喜欢他。
正：They are such clever children that we all like them.
这些孩子很聪明，我们都很喜欢。
----
幻灯片 17误：They are so clever children that we all like them.
此时的so…that…结构可与such…that…结构转换：
It's such an interesting film that we all want to see it.
这电影很有趣，我们都想看。
It's so interesting a film that we all want to see it.
这电影很有趣，我们都想看。
----
幻灯片 18注意：在much, many, little, few这4个词前总是用so而不用such。
He had so many falls that he was black and blue all over.
他摔了许多跤，结果全身都是伤。
He earns so little money that he can hardly feed his family.
他赚的钱很少几乎不能养家糊口。
----
幻灯片 192．结果状语从句与不定式短语的转换
由so that和so…that引导的结果状语从句有时可与表结果的so as to和so…as to引出的不定式短语转换。
He arrived late so that he missed the train.
⇒He arrived late so as to miss the train.
他到得很迟，结果未赶上火车。
----
幻灯片 203．so that引导目的状语和结果状语的区别
(1)含义上的区别：引导目的状语从句时表示的是一种意欲或可能性，引导结果状语从句时表示的是一种事实。
(2)形式上的区别：引导目的状语从句之前不用逗号(说话时也不停顿)，而结果状语从句之前则通常有逗号(说话时常有停顿)；有时引导结果状语从句时其前也可以没有逗号，此时可看从句中是否有 can / could, may / might, will /would 以及should等情态动词，如果没有，则多半是结果状语从句。
----
幻灯片 21I am going to the lecture early so that I'll get a good seat.
我想早点去听演讲，以便找个好座位。(so that 引导目的状语从句)
I went to the lecture early so that I got a good seat.
我去听演讲去得很早，所以找了个好座位。(so that 引导结果状语从句)
另外，so that引导目的状语从句时有时可放在主句之前，而引导状语结果从句时却不能。
----
幻灯片 22正：So that he could buy a new car, he saved a lot of money.
他节省了一大笔钱，以便能买辆新车。(引导目的状语从句)
误：So that I could hardly stand, I was tired.
(引导结果状语从句不能置于句首，可改为I was tired so that I could hardly stand. 我很累，几乎站不稳了。)
----
幻灯片 234．so…that…和such…that…有时不引导结果状语从句
so…that…和such…that…可以引导结果状语从句，但并不是说它们引导的从句就一定是结果状语从句。请看以下句子：
I'm so happy that you could visit us.
我很高兴你能来看望我们。(其中的so用于加强语气，相当于very)
It's such a great pleasure that you are here.
你在这里是非常令人高兴的事。(其中的that引导的是主语从句，句首的it为形式主语)
----
幻灯片 24四、目的状语从句
1．引导目的状语从句的从属连词
主要的有 in order that, so that, in case, for fear等。
Speak clearly so that they may understand you.
讲清楚些，以便他们能理解你。
Shut the window for fear that it may rain.
把窗子关上以防下雨。
注意：so that引导目的状语从句时有时可省略so而只用that，有时也可只用so。
----
幻灯片 25Bring it closer that I might see it better.
拿近些，使我能看得清楚些。
I'll show you so you can see how it's done.
我将做给你看，以便你知道应怎样干。
----
幻灯片 26
2．目的状语从句与状语短语的转换
为了简洁起见，当目的状语从句的主语与主句的主语相同时，目的状语从句有时可用表目的的不定式短语替换。
He got up early so that he could catch the early bus.
He got up early so as to catch the early bus.
他起床很早以便赶上早班车。
----
幻灯片 27He came in quietly in order that he shouldn't wake his wife.
He came in quietly in order not to wake his wife.
他轻轻进来，以免把他妻子吵醒。
有时还可与表示目的的介词短语替换：
He left an hour early for fear he might miss the train.
He left an hour early for fear of missing the train.
他提前一小时离开，以免错过火车。
----
幻灯片 283．in case引导从句的区别
in case既可引导目的状语从句，也可引导条件状语从句，主要视句意而定：
In case he comes, let me know.(条件状语从句)
如果他来，告诉我一声。
Tell me in case you get into difficulty.(目的状语从句)
遇到困难请告诉我。
in case引导目的状语从句，从句有时可用“should＋动词原形”这样的形式：
Take your coat in case it rains (should rain)．
带着雨衣以防下雨。
----
幻灯片 29五、条件状语从句
1．引导条件状语从句的从属连词
(1)主要的有if, unless, as (so) long as等。
You can leave now if you like.
如果你愿意现在就可以走了。
As long as it doesn't rain we can go.
只要不下雨，我们就可以去。
(2)除以上基本的引导条件状语从句的从属连词外，还有的动词尤其是其分词形式(如suppose, supposing, provided, providing等)和介词短语(如in case, on condition that等)也可用作连词表示条件.
----
幻灯片 30I will come on condition (that) she is invited too.
如果邀请她来， 那我就来。
He may go with us provided (providing) he arrives in time.
他若及时到，就可以和我们一起走。
suppose和supposing引导条件状语从句时，通常用于主句为疑问句的场合：
Suppose the boss saw you，what would he say?
如果老板看到你，他会怎样说？
Supposing he does not come, shall we go without him?
他若不来，是不是不带他去？
----
幻灯片 312．条件状语从句的时态
当主句为将来时态或具有将来意义时，条件状语从句通常要用一般现在时表示将来意义，而不能直接使用将来时态。
----
幻灯片 32六、时间状语从句
1．除基本的引导时间状语从句的从属连词外，还有些本来不是从属连词却可用作从属连词的词：
(1) 表示“一……就……”的从属连词：the moment, the minute, the second, the instant, immediately, directly, instantly, once, no sooner…than…， hardly…when…等。
Immediately he came I told him the news.
他一来我就把消息告诉了他。
----
幻灯片 33The moment I saw him I knew there was no hope.
我一看到他就知道没希望了。

我们刚出发就下雨了。
Once he arrives, we can start.

----
幻灯片 34(2)涉及time的几个从属连词：every time(每次)，each time(每次)，(the) next time(下次)，any time(随时)，the last time(上次)，the first time(第一次)。
Every time I see her I'll think of it.
每次我看到她，我就想起这事。
He felt nervous each time she spoke to him.
每次她和他讲话，他都感到紧张。
----
幻灯片 35
2．与时间状语从句有关的时态问题

Turn off the lights before you leave.
走前关灯。
I will tell him as soon as he arrives.
他一来我就告诉他。
----
幻灯片 36(2)与since 从句搭配的主句的时态通常是现在完成时态。
He has lived here since 2012.
自2012年以来，他就一直住在这儿。
Where have you been since I last saw you?
自我上次见到你之后你到哪里去了？
----
幻灯片 37注意：在特定的语言环境中有时也可能用过去完成时或一般现在时：
