Please give this message to him when he_________(come)back.
She lives in the_________(five)floor of the building.
He is  _______(tall)than any other boy in his class.
  5.  I _____(shake)hands with Miss Liao and Mr Gao yesterday.
  6.  It _______(be)rainy yesterday afternoon.

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.
