2.stay\last\keep\remain既可作动词又可作系动词,
last①持续、继续…，如：
The flowers show lasted a week. 花展持续了一周。

How long will this battery last?

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。
3.hold的抓住是掌握,把握,控制这方面的意思,所以不可以选...
