also后加动词ing?

also只是一个副词，用来修饰动词用的，不能决定其后动词加不加ing形式
I am also reading books. 我也在看书。
此句子是read 放在am后，加ing构成现在进行时，和also没有关系

简析also, too, as well和either用法

also, too, as well, either,作“也”讲，为副词。下面分别讲述：

一. too, also, as well：都用于肯定句，表示前者怎样后者也怎样。

too：一般放在句尾，可用逗号和前面的句子隔开，也可不用；

also：其位置大多放在be动词、助动词、情态动词之后，实义动词之前；

as well：其位置一般放在句尾，三者可以作同义句转换。例如：

You need to go shopping and I need to go shopping, too.

=You need to go shopping and I also need to go shopping.

=You need to go shopping and I need to go shopping as well.

also和too的用法和区别
also 在语气上比too更正式，语气较重，只用于肯定句，一般紧靠动词。
-- He was also an
artist and lived at Compton（他也是个艺术家，家住康普顿）
-- He is gentle, but he is also
capable of fierce intellectual combat. (他很温和，但他却也能够进行激烈的斗智)

Too
语气较轻，多用于口语，在肯定句中使用，通常位于句末。
-- He's a singer and an actor
too（他是个歌手，同时也是演员）。
-- If you buy a car, you'll need a parking place, too.
(如果你买辆车，你还将需要一个停车场地)

可见二者区别是also正式，一般紧靠动词；too多用于口语，通常位于句末（如果用于句中，需要用逗号隔开，如：If
you buy a car, you'll, too, need a parking place.）

不是得，also 后加动词原形。或者根据时态来定。
如：He also likes to play football
He also failed the exam.
