1、knock表示敲门的时候与at是固定搭配
2、needn't have come 表示的是你应该这么做但是现实是你并没有这么做,语法是情态动词should或need 等+ have +done
3、need这里是情态动词,相当于should,所以不能加s
4、这句你如果知道moved翻译成“感动”,就知道意思了.选择deeply
他被这个老师的故事深深打动了

1.knock 不及物动词,后面必须跟介词 knock at 敲门
2.need此处为情态动词,后面加动词原形
3.need 为情态动词
4.他被老师的故事感动了,deeply 深深的,选C

1:knock at接名词
3:need sb do sth
4:他被老师所说的故事深深的打动了,用deeply
