解析：本句的主干是：The five-year-old Kong would practice on the paper piano；as 引导时间状语从句，意为：一
边…，一边…，强调主句和从句的动作或事情相并发生。
As my mother sang those old songs, tears ran down her cheeks. 当我妈妈唱起那些老歌时，眼泪顺着她的脸颊流了下来。 翻译：伴随母亲用手打的节拍，5岁的孔祥东在纸钢琴上练习弹琴。
解析：本句主干为：This is，why 引导的句子做表语成分，因此为表语从句。如： The trouble is that we are short of money. 困难是我们缺钱。
翻译：这就是为什么他追根溯源，重新发现了中国民族音乐之美的原因。
解析：本句中whether…or引导的让步状语从句，意为：不管…还是…，说明两方面的可能性都不会影响主句的意向 或结果。如：
You'll have to attend the ceremony whether you're free or busy. 不管你忙不忙，都要参加这个典礼。
翻译：不论孔祥东改变他的形象还是对音乐进行改革，他都是当今音乐界的先锋。 出题建议：确定好题型后，可在关键词中输入：whether...or。
解析：本句主干为：They are dressed in beautiful costumes；现在分词skipping back and forth…做伴随状语，与主
语They之间是主动关系。如：
Don't sit there doing nothing. Come and help me with this table. 别坐在那儿什么都不做，过来帮我收拾桌子。
翻译：他们穿着漂亮的衣服，伴着响亮的鼓点儿，扭来扭去。
解析：本句主干为：Popular or social dances often come from folk dance；although 引导的让步状语从句。
翻译：流行舞或交谊舞通常是由民间舞发展而来，但这些舞蹈通常只流行一小段时间。 拓展：although 和though 都可以引导让步状语从句，通常可以互换，区别是： 1. even 能和though 组合表示强调，但even 不能和although 组合。
2. though可以独立用作副词，常放在句末，意为all the same （还是；仍然）或however（可是；然而），而
although 无此用法。 如：
She didn't tell me what she had done, but I know it though. 她没有告诉我她所做的事情，但我还是知道了。
三、重点语法
will表示“临时决定”，在实际考查中，经常跟be going to 对比：
will be going to 提前计划，安排，打算依据 表将要 临时决定 表示“将要”： 1. ---“Kate is in hospital.” ---“Oh, really, I didn't know. I will go and see her at once.”（临时决定去看Kate）。 2. ---“Kate is in hospital.” ---“Yes, I know. I am going to see her this afternoon.”（提前已打算好去看Kate） 1. --- When will you come to see me, dad? --- I will go to see you when you ______ the training lessons. A. will be finished B. will finish C. are finishing D. finish 2. ---- I'm sorry that John is out. --- Please ask him to call me as soon as he ______. A. returned B. returns C. will return D. is returning 解析：
1. D. 主句为一般将来时，在when 引导的时间状语从句中，要用一般现在时表将来。
2. B. 在时间状语从句中，若主句使用一般将来时，从句则使用一般现在时。此句中的主句是祈使句，它表示的动
作还没有发生，相当于一般将来时。 该考点下，同学们需要牢记：
在时间状语从句中，当主句用一般将来时（祈使句或含有情态动词），从句用一般现在时表将来。即“主将从现”。
You should be quiet when you attend the meeting tomorrow.
考点：引导词的选用
1. --- You bought the car about ten years ago? --- Yes. ______ it’s old, it still runs well.
A. Because B. Since C. Although D. But 2. --- Will you go to Tom’s birthday party tomorrow? --- No, ______ I’m invited to.
A. if B. until C. when D. even though
3. ______ I have been working in Guangzhou for five years, I still can not get used to living in the hot climate.
A. When B. While C. Since D. As
4. You should try to get good night's sleep ______ much work you have to do. A. however B. no matter C. although D. wherever 解析：
1. C. because 意为“因为”；since 意为“既然；自从”；although 意为“尽管”；but 意为“但是”。根据句意前后为转折 关系，故选C 项。
2. D. even though 用来引导让步状语从句，意为“即使”，符合题意。if “如果”；until“直到”；when “当…时候”。
3. B. while 意为“虽然”，引导让步状语从句，相当于although。
4. A. however 相当于 no matter how，意思为“不管怎样…”，但是no matter 不能单独与much 连用；although 与
wherever用在此处均属结构错误。 该知识点总结如下：
让步状语从句顾名思义就是“让了一步”。一般含有“虽然；即使；尽管；无论”等意思。
引导词的选择是重点。引导让步状语从句的连词主要有：though, although（虽然），even if，even though（即
使），no matter + 疑问词，疑问词+ever，while（虽然），as等。注：while 当“虽然”讲时，是从属连词，相当 于although.
注意：让步状语从句也要遵循“主将从现”原则。
because /since /now that/as/ for用法和区别:
1. because 通常表示直接的原因，语气很强，用来回答why的问题。 例： We couldn't go out because it was too cold. 因为天气太冷，我们不能外出。
2.since/now that（既然）语气较弱，强调已知的事实。例： Since you can't answer the question, I'll ask someone else. 既然你回答不出这个问题，我就问别人了。
3. as 意为“由于”，语气比because 弱，表示不言而喻、显而易见的原因和理由。如：
As it was late, we came back soon. 由于时间很晚了，我们很快回来了。
4. for 是并列连词，表示推断的原因，或对前一分句补充说明理由。 例： It must be morning for the birds are singing. 一定是清晨了，因为鸟儿在叫。
通过下面三道题，看相关so/such...that考点：
1. The teacher taught us in such a lovely way _____ we would never forget what he taught us. A. as B. that C. so that D. which 2. --- Did you catch what the teacher said?
--- No. She spoke so fast ______ I couldn't hear her very clearly. A. which B. that C. when D. Since
3. There are ______ few problems left ______ I believe you can deal with them yourself. A. such; that B. so; that C. such; as D. so; as 解析：
1. B. 考查结果状语从句，such + (a/an) + adj. + n. + that...。句意：这位老师的教学方式如此生动，以至于我们永
远都忘不了他教授的内容。
2. B. 句意为“她说得太快了，我听不清楚她说什么。考查结果状语从句的引导词，so + adj./adv.+ that...。 3. B. 考查结果状语从句引导词选用，虽然句中有名词problems，但因为名词前few，只能选so...that...。 so/such区别如下： 名词such 形副so； such+(a/an)+adj.+ n.+that... so+adj./adv.+that… so+adj.+a/an+可数名词单数+that... 多多少少，都用so little一词有多义 小用such，少用so 拓展：so that 用法 既可引导结果状语从句也可引导目的状语从句。目的状语从句里常含有情态动词may, can, might或could等。比较 下面两个句子的意义和结构，就很容易区别了： He spoke at the top of his voice so that the students at the back could hear him. 他说话声音很高，为了后面的同学能听见。(目的状语从句，so that=in order that） He spoke at the top of his voice, so that the students at the back heard him. 他说话声音很高，结果后面的同学都听见了。(结果状语从句) 注意：两种从句so that都位于句中，不放在句首。 通过下面两题，清晰考点： 1. Roses need special care ______ they can live through winter. A. because B. so that C. even if D. As so+many/much/few/little等+名词+ that... so+little（少）+ n. + that.. such+a little（小）+ n.+that...
