根据提示，完成下列句子，注意状语从句与主句的时态关系
　1. When I arrived at the airport, the plane ____________(起飞了)．
【解析】 had taken off　主句“起飞”动作发生在从句动作“到达”之前。
5
状语从句的时态与主句有什么联系？
had taken off
5
2. What are you going to be ________________ (当你长大时)
【解析】 when you grow up　从句动作“长大”与主句状态动词“干什么”同时发生，均用将来时态。但此处从句动词时态为一般式表将来。
when you grow up
5
3. She burst into tears as soon as she__________ (被告知) of her failure in the interview.
　
【解析】 was informed　在as soon as 引导的“一……就……”句型中，从句动作与主句动作衔接紧凑，可理解为(几乎)同时发生。
was informed
5
4. Because I __________(进行) a conversation with my parents, we reached better understanding of each other.
【解析】 had had　从句谓语动词动作have先于主句谓语动词动作reach发生。
had had
5
从句与主句的时态关系是通过从句与主句的谓语动词动作(或状态)发生的时间关系来确定的：从句谓语动词动作(或状态)先于主句谓语动词动作(或状态)发生；从句谓语动词动作(或状态)与主句谓语动词动作(或状态)同时发生； 从句谓语动词动作(或状态)后于主句谓语动词动作(或状态)发生。因此，从句和主句各自的时态应该彼此参照使用，注意彼此时态在逻辑意义上的一致性。但要注意在时间状语
5
从句和条件状语从句中，一般式表将来。如：When you come (不用will come)here tomorrow, I will be on the way to Shanghai；If I succeed (不用will succeed) in passing the exam next month, I'll be no longer stressed.
时间状语从句的从属连词when, while，as用法上有何区别？
根据句子意思选择最佳词语(when, while，as)填空(每空一词)
　1. __________she came in, I was watching TV.
2. Would you please look after my pet dog __________I was away on business
　
6
while　
When　
3. The head teacher laughed __________he spoke. Obviously, he was satisfied with our performance.
6
as
6
表示 “当……时候”时，when可接短暂性或延续性动词，既可表点时间，也可表段时间；while只能接延续性动作，表段时间；as强调两个动作同时发生，常译为“一边……一边……”。
原因状语从句的从属连词as, since, because用法上有何区别？
根据句子意思选词(as, since, because)填空(每空一词)
　1. It is __________ he is ill that he isn't here celebrating your birthday.
　2. __________ you have known the truth from head to toe, I won't give any explanation.
7
because　
Since　
3. __________ the weather is not so helpful, we had better prepare two plans in advance.
7
As
7
表达原因时，使用as, since，because等从属连词，它们的区别主要是语气上的区别，但在实际运用中，语气是很难把握的东西，因此掌握相关句式和含义是关键。because语气最强，表示与结果直接相关的原因，可译为“(正/就是)因为”，所以常用于强调句型或回答why引导的问题。since表示顺承关系，表达说话者认为合乎情理的逻辑推断，可译为
7
“既然……(就……)”，此时用法上相当now that。as语气比较弱，常译为“由于”，不强调原因时，有时可与because通用。特别注意，for也可以表示原因，但它是并列连词，用法上注意两点： 不放句首(语气弱)；引出补充说明的原因，不必直接翻译成“因为”。如：Come up to me, for I have something important to tell you(过来，我有要事对你讲)．
让步状语从句的从属连词though, although, as, while用法上有何区别？
根据句子意思选词(though, although, as, while)填空
1. ________________________ the Internet has so many conveniences, it also has a lot of inconveniences.
2. _________________ the actress is beautiful, I don't like her.
8
While / Though / Although　
Though / Although
3. Child _______________ he is, he is the first Chinese to travel across Europe alone by bike.
8
as/ though
8
表达让步含义时，常用从属连词though, although, as, while引导让步状语从句。while强调对比，只能放句首，以引出相对或相反的情况，译为“在……同时，却(有相反的情况) ”，此时可以用though或although替换。though与although大部分情况下可以互相替换，既可放句首，也可放句末。as 引导让步状语从句必须倒装，此时可以用though替换，但不可用although替换。
时间状语从句的从属连词till, until用法上有何区别？
根据句子意思填空(till, until)选词
　1. Yesterday, I waited for you at the bus station __________ 4 o'clock in the afternoon.
　2. __________ you told me, I had heard nothing of what happened.
9
until / till　
Until　
3. Not __________ the war ended did he return home.
　4. It was not__________ the result of the exam was announced that he realized he had organized time badly.
9
until　
until
9
这两个连词意义基本相同。两个连词均可用于肯定形式，表示 “做某事直至某时”，此时动词是延续性的。在否定形式表达 “直至某时才做某事”时只能用until，此时动词为非延续性。另外注意表示“直到 ……才”意义的倒装句型和强调句型。
10
状语从句中“一般式表将来”的含义是什么？

________________________at 8 o'clock tomorrow morning, I'll send a car to pick you up.
