Please give this message to him when he_________(come)back.

5. I _____(shake)hands with Miss Liao and Mr Gao yesterday.
6. It _______(be)rainy yesterday afternoon.
7.I______(drop)my glasses in the swimming pool yesterday.

Answer 1

谢邀请，答案和详解如下：
1，are having。 现在进行时be+Ving，主语复数，所以用are

2，comes， 祈使句加条件状语从句，从句中用一般现在是表示将来时态。且主语为第三人称单数，故用comes。

3，fifth，序数词，第五层，用the fifth floor。注意five的序数为fifth。

4，taller ，形容词比较级+than +sb/sth，比其它男生都高。不能用最高级tallest形式，如果用最高级，该句应该改为：He is (the tallest ) boy in his class.

5，shook， 一般过去时，昨天跟人握手，用动词shake的过去式shook（注：shake的过去式是shook，过去分词是shaken，要死记硬背这些特殊动词变化）。

6， was，同第五题，be动词的过去式用was（单数第三人称后用was）

7， dropped，同第五题，一般过去时，注意drop的过去式要双写p。

以上解释，希望你能够帮到你！祝你英语突飞猛进。
