[文法] all is v or ving?

[chevalierxd (獨孤求噓-風青羊)]

all he wants to do is work in a dreary factory

她想做的事就只是在沉悶的工廠工作

為什麼不是用working?

→ dunchee:這是固定用法。參考我以前寫的: http://ppt.cc/hsB7  #6

推 fhsd4264:Because "in a dreary factory" as an adjective clause.
→ fhsd4264:"All he wants to do is work" is correct. "All he
→ fhsd4264:wants to do is working" doesn't make sense.
