Question

such as 引导两个主语谓语动词用单数还是复数

Answer 1

若后接动词,通常用动名词,有时也可用动词原形.如：
Don’t do anything silly such as marry him. 不要做什么蠢事,比如说去嫁给他.
Magicians often perform tricks such as pulling a rabbit out of a hat. 魔术师常常变从帽子里抓出兔子的戏法.
用于such as to do sth,表示程度或结果.其中的such是代词,as to do sth引出的结构作程度状语或结果状语.如：
Her illness was not such as to cause anxiety. 她的病不是很重,不必担心.
The pain in her foot wasn’t such as to stop her walking. 她脚疼,但还不至于不能行走.
