Question

请教英语语法 remain and keep

这两个有啥区别.

you must keep the rom warm.

为什么不用remain

Answer 1

remain 常可与stay 互换, 但它强调“继续停留于一处或保持原状态、情况性质而不改变”, 如:
This place remains cool all summer.
这个地方整个夏天都凉爽。
stay强调“某人[物]继续留在原地而不离开”, 如:
He stayed to see the end of the game.
他一直呆到比赛结束。

keep 系常用词, 指“使继续下去”“使较长时期地置于不脱离控制、掌握、照料或变化之下”, 如:
keep the room clean.
保持室内清洁。

Answer 2

stay、remain和keep辨析

1．表示“继续呆在某处”时，应该用不及物动词remain或stay，例如：

Shall I go or stay?

Stay indoors for a few days until you recover from your cold.

He remained in his seat after all the other students had gone home.

2．表示“暂住、短期停留”时，只能用不及物动词stay。例如：

He is staying at Hilton Hotel.

My mother-in-law stayed with us this week when she visited us.

3．表示“残留、剩下”时，只能用不及物动词remain，例如：

Not much of the house remained after the fire.

Of the seven brothers, only four now remain; the rest are dead.

4．表示“继续保持或处于某种状态”时，应视具体情况在上述动词中进行选择：

(1)表示“继续保持或处于原来的状态”时，可用remain或stay，例如：

Three of them remained single.Shops should remain open till later in the evening.

The door stayed closed.But the police themselves prefer to stay unarmed.

(2)表示“需要设法才能保持或处于某种状态”时，应用keep，例如：

She knew she must keep calm. I wish those children would keep quiet.

Although they have many difficulties, they keep happy.

Paul managed to keep awake by drinking lots of strong black coffee.

(3)表示“使某人或某物保持某种状态”时，只能用及物动词keep，例如：

She had kept him waiting twenty minutes on this occasion.

Why do you always keep your windows closed?

Answer 3

我记得有个短语叫做keep sth + adj.表示保持某物在某种状态中

remain是个不及物动词，后面不能跟上宾语

如果用它来表达这句话，直接在remain后跟上形容词就可以了
而且是物作主语才能用（rom应该不对吧？是room）

表达为：The room remains warm

Answer 4

原因很简单
remain是不及物动词
