I don't like to be looked at by the others. 

我想问一下不及物动词加介词等于及物动词，那么比如上面这句, by和at都是介词这样写是否有误?

【答】网友的句子不错。

网友的问题，属于“短语动词的被动语态”。即有些不及物动词可以加介词，构成短语动词。这些短语动词，有的是可以变成被动语态的。常见的有：adhere to （坚持），look at（看）, look after（照料）, listen to（倾听）, move into（搬入）, break into（破门而入）等。例如：

Ancient buildings are carefully looked after. 古代建筑被精心地保护着。

The new song is not popular and is seldom listened to. 这支新歌不受欢迎，很少被人听。

以下是look at 的被动语态。此时，look at 除了“看；观看”外，还有引申义：审视、审查、看作、研究等。例如：

I'm taking my car to the garage to be looked at.  我要把汽车送到修车厂去检修。

The implications of the new legislation will need to be looked at.  新法规的含义需研究一下。

The sun can be looked at through smoke glass.  可以通过烟玻璃观看太阳。

A surface can be looked at in two ways.  一个面可以用两种方式验证。

Pennies are looked at before they are spent.  花钱都要经过再三审核。

My work hasn't been looked at for a week. 我干了一个星期的工作也没人看一眼。
