Answer 1

平常我们使用词组aim at 是主动含义，表某人打算、准备做……的意思。比如His parents aim at improving his grades,his parents sent him to the school.就可以用非谓语表达：Aiming at improving his grades,his parents sent him to the school.这里父母作为主语,是主动状态,想要送他去学校来提高成绩.父母（主语）和打算（谓语动词）之间是主动关系.
但是如果主语和谓语动词是被动关系,就用be aimed at.例：They aimed at showing off their love,so the picture was put in the diningroom.此处aim at 和人构成主动关系和picture 不是主动关系，所以用非谓语表示只能是The picture,aimed at showing off their love,was put in the dining room.这张被用来炫耀他们的甜蜜的照片被摆在了餐厅里。那么使用aiming还是aimed主要是看主语与谓语动词的主被动关系来选择.

Aimed at little children, the film was very popular with most of us. 这部电影以儿童为目标，深受我们大多数人的喜爱。
Aimed at 是固定搭配。释义：目的在于；旨在；瞄准；

Aiming at 放句首主要是表达针对的意思。 Aiming at this question针对这个问题；Aiming at these problems 针对这些问题
这里主要考固定搭配吧。
