let的用法:
1)当let后只有一个单音节动词,变被动语态时,可用不带to的不定式。
They let the strange go.---> The strange was let go.
2)若let后宾补较长时,let通常不用被动语态,而用allow或permit代替。
The nurse let me go to see my classmate in the hospital.
----> I was allowed/permitted to see my classmate in the hospital.
句型:
一、let sb do sth.“让某人做某事”,如:
Let's have a break.让我们休息一下吧。
It's time for the class. Let's go to the classroom.上课的时间到了,我们进教室吧。
二、由“let”开头的祈使句是个常见的动词句型,它的主要用法有下列三种:
表示“建议”。在此句型里的“let”后头紧跟着一个第一人称的代词宾语,如
(1)Let me try.
(2)Let's do it.
(3)Let me go.
此句型语气委婉,比直接的祈使句客气。试比较句子的差别:
(4)a. Don't disturb him.
b. Let's not disturb him.
其中a句是直接命令,语气强烈,而b句带有建议的意味,语气婉转温柔。
