Answer 1

1.are talking,对不起，我不知道你在说什么。从句时态是现在进行时
2.will not go. 恐怕我明天不能去参加聚会。从句时态为一般将来时。
3.had typed. 在老板进来之前她刚好打完这封信。before表示某件事在另外一件事之前完成，从句时态为一般现在时，主句事件先于从句完成，所以主句用过去完成时。
4.was watering .当电话铃响的时候，我正在浇garen。主句用过去进行时。
5.told。本句时态为一般过去时。
填空
1.when
2.if
3.that
4.what
5.that
以上填空可根据句子意思填出来的，建议多读点课文多背点单词哈
