不好意思。第2题横线后面加个work.第4题横线后面加一个painful.我漏打了。能再回答下吗？

1 an 因为S 音标/es/,第一个音素是/e/是元音音素.区分元音音素开头的单词,不是元音字母.
2 the
3 that 指代上文,this引出下文.
4 much too 修饰形容词 a lot 修饰动词.
5 on 有限定词修饰的上午,下午,傍晚,夜晚就用on.
6 都用一般现在时或者都用一般过去时态（表示过去一直做的事情）.
7因为不知道做完没有,可能还在做呢,用的现在完成进行时.
8be frightened at 主语是人.frighting 主语是事物.
9 去掉j句首的you.是祈使句的反义疑问句.用 will you!好吗?
再问：高手阿。能不能再解释一下第儿题为什么选；the
再答：选我最佳答案吧，呵呵。说高手，惭愧了。这都不是什么难题。我教初中英语的。二题的 the 是构成 finish the work. the 是特指的或者双方都知道的work.这里的句子意思很明显是特指。要不然完成什么工作呢，听话人不明白了。
