Some day later,he had to leave for another city.
很明显,这是在描述过去的事情.
Take good care of the plants when I`m out.祈使句.前面也可以加please.所以不用ing.

(1)have to表示“必须,不得不”,have的过去分词为had。
(2)take good care of something or somebody,照顾好某事或某事,为固定搭配。

第一题因为是过去时,所以是had to,句中出来"later",一般就表示过去的时间。
第二题是祈使句,也就是直接动词原形。如果用to do不定式,或者动名词,那么这句句子就不完整了。taking good care of the plants when i'm out这句句子没有主谓宾,只有一个状语从句,不成句子。...
