例句

a.表命令、决定、规定、提议等词语之后that-分句中,用动词原形。
suggest,demand,advise,propose,order,arrange,insist,command,require,request,desire……that+(should)do
例如Hesuggestedthatweshouldleaveearly.
Mysuggestionisthatweshouldtellhim.
b.Itis(was)形容词/名词that……(should)do/
例如Itisabsolutelyessentialthatallthefactsbeexaminedfirst.
3.某些句型中虚拟形式:
1.It’s(high,about,thefirst,etc.)time(that)…动词过去时…
例如It’stimeweleft.例如Itistimewewenttobed.
