1.This is what you have to do at the weekend----___your hair
1. 为什么选C .此处破折号后边是一个祈使句.
2. C.which
选C 有范围的选which没范围的选what 对的,因为前面有提到在两个中选,所以用which.
3. 选D 此处主语是一个比较抽象的概念,用单数.用be to do,不定式表将来.
4 选A 有last night表过去的时间词,用过去式,所以waited.第二个空表示过去某时刻(听到消息)的过去,对那时刻的影响(就不能来赴会了),所以用过去完成时.
5. 选C 此处的he‘s 是he has的缩写,从后面的turned in 可判定,these days也常常与完成时连用,而seldom使本句有否定意义,所以问句用肯定.
不懂追问~
再问: 第五题的第一个空可不可以是was waiting 因为昨天晚上的两个小时一直在等
再答: 不能。表述过去某个事实,用一般过去式。此处就是这样,强调一个事实,而不是说明某时刻正在干某事。 过去进行时在于强调过去某个“时刻”正在做什么。比如 I was doing my homework at that moment.
