学后反思
当堂达标答案与解析:
Ⅰ. 1. A too much“太多”修饰不可数名词;too many“太多”修饰可数名词复数形式;much too“太”修饰形容词或副词;many too表达错误。work是不可数名词,故选A。
2. C 根据句意“西安是一个历史悠久的大城市”可知,空格处应填with“带有,具有”。
3.D chance“机会”;success“成功”;increase“增长”;problem“问题”。根据句意“问题是我的女儿太小以至于不能照顾自己。我该怎么办呢?”可知选D。
Ⅱ. 1. caused 2. increased 3. noise 4. report
Ⅲ. 1. noisy 由空格前连系动词is可知,此处应填noise的形容词形式noisy作表语,构成系表结构。
2. is 由空格后的increasing now知本句时态为现在进行时,当population表示整体时谓语动词用单数形式。
3. called 此处要用过去分词短语作后置定语,修饰前面的名词the man,故此处填call的过去分词形式called。
Ⅳ. 1. Don’t spend too much time in front of the computer screen.
