Structure
 
In this part ,we'll do exercise of structure. We'll sum up the basic knowledge and their patterns so that you'll have some clear idea about them.

语法小知识

1. sentence pattern (spend … doing sth.)
2. except, except for
3. used to do sth.
4. the independent element(独立成分)


1. sentence pattern : (spend…doing sth.)
例如:He's spent his life writing this book. spend
常用的结构还有:
  spend…in doing 花费…做某事 (in可省略)
  spend…on sth. 花费…在某事、物上 (on后只用名词或代词)
  例如:"How did you spend your summer vacation?" "I spent it (in) reading and fishing."
  He spent all his savings on a new car.

2. except, except for 都指"除…之外,再不包括",但except 指从整体中将个别特殊的排除出去,
  而except for 表示某种理由或细节,在一定程度上修正了前面句子所述的主要意思。
  另外,except for 可放在句首,而except 一般不置于句首。
  例如:He gets up early every day except Sunday.
  I like her except when she is crying.Except for this, everything is in order.
  The skirt is OK except for the color.

3. used to do sth.
  是一个用于表示在过去常做的动作或出现的状态的句型。
  在构成否定句和疑问句时,常借助于did,同时也可用used直接作助动词。
  例如:I didn't use to play football at school. (= I used not to play football at school.)
  Did you use to be afraid of dogs? (= Used you to be afraid of dogs?)
  In your boyhood, you used to play with Xiao Liu, didn't you?
  There used to be an old pine tree here, wasn't there? 从前这里有棵古松,对吗?

4. most curious of all 是独立成分,称为插入语,相当于 What is most curious of all。  
 插入语包括独立不定式、独立分词、由to引导的短语以及诸如frankly, on the whole, honestly, what is worse, worst of all, last but not least, what is more important, most important of all等副词或短语。插入语的功能在于表达句子中间的某种递进、顺序、承接关系,作者对某一问题的解释、总结,或者作者对某一问题的看法、态度。
  例如:To tell the truth, I don't like it.Strictly speaking, he is not qualified.What is more important, we have improved our equipment.(Well, let's do the following exercise together. Check the answer with the key carefully.)
