such as加动词时什么时候用ing形式什么时候用原形

优质解答

such as后加的动词ing是动名词形式,在such as后用作名词.such as后也可以加动词原形,但没那么太常见,我学那会也没见着几个.给你俩例句看看吧,这玩意就是语境,理解和自己语感的问题.
I have a lot of things to do every day, such as cleaning, shopping and writing.
动名词用
Don’t
do anything silly such as marry him
原形用
You can do something else, such as cleaning the room
注意一下这种情况,上面的clean后面加了ing但并不是动名词的原因,而是因为“cleaning the room"是作为“打扫房间”一个词组跟在such as后面的.在这里只是提醒一下做题的时候不要只盯着动词什么的,要注意全句再做决定
