同样的作用于英文

The advertisement has the same effect on different people.

This advertisement had the same effect on different people.

Sth will have the same effect

We decided the work是主句，he to clean the window and I sweep the floor是后置定语来修饰work，而且根据英语里面的省略应该是he to clean the window and I to sweep the floor,但是因为重复了就省略了，就是这样

also一般用于肯定句，有强调意味，位于主谓语之间，即实义动词之前，助动词之后。如：I can also do it.我也能干那个活。as well多用于口语，一般不用否定句，通常放在句末，强调时可放在句中。
