LET 點用?

let 跟 bare infinitive, 指 讓, 準許
(通常不用被動式)
he would not let the child do it.


Let's means let us
Let's xxx implies a suggestion
(用於祈使句,表示建議,請求,命令等)讓
e.g. Let's go swimming.

let 還有以下解釋

出租,租給
Mrs. White let me a room.
懷特太太租給我一間房間。

(用於祈使句)假設;即使
Let the two lines be parallel.
假設這兩條線平行。
Let X=5 and Y=2.

LET 同 make 等字一樣，
後面要跟 BARE INFINITIVE，
即係你所講嘅 BASE FORM 喇~
不如等我寫D EXAMPLES 啦,,,
> She would not let the child do it.
. 她不會讓孩子做這事的。
> The news made John irritable.
. 這消息使約翰煩躁不安。
> His jokes made us all laugh.
. 他的笑話把我們都逗笑了。

其實 LET'S 嘅 'S 係 US 嘅 SHORT FORM，
喺口語嘅英文經常出現~
但係作文就盡量寫番 LET US,,,
LET'S GO 同 HERE WE GO 嘅意思相若，
即係 "我地開始喇!!" 咁解,,,
其實 US 係個 PRONOUN,
LET 後面唔一定跟 US ((呢點我諗你都好清楚架喇 =.=''))
