let stand 的意思是

下面一段是2017年高考考试英语天津卷阅读理解D的一个段落：

A cousin to the Watched-Pot Wait is the Forced Wait. This one requires a bit of discipline. Properly preparing packaged noodle soup requires a Forced Wait. Directions are very specific. “Bring three cups of water to boil, add mix, simmer three minutes, remove from heat, let standfive minutes.” I have my doubts that anyone has actually followed the procedures strictly. After all, Forced Waiting requires patience.

不理解 let stand 的意思和使用方法。

特别是 stand 是什么词性？的意思是？

let stand five minutes 是省略说法。let stand + 时间段，已成为习语。意为“静置（平静放置）多久”。

实质是，这是 let 后面的宾语被省略。stand 是动词，原本作宾补。没了宾语，也就不再是宾补了，作为固定词组记忆即可。补全为：

let the three cups of water stand for five minutes

让这三杯水静置五分钟。

又如：

Heat the mixture until hot about 2 minutes. Remove mixture from heat; cover, and let stand 30 minutes.

将混合物加热大约2分钟，移离火源，封盖并存放30分钟。
