Question

~.~1006(1)句子语法的问题，谢谢llllllllllllllllllllllllllllll

1.as he walked,he looked over his shoulder again and again
他一边走，一边不时转过头向后张望
looked over his shoulder 是什么意思？

2.we heard the sound of something running,but we could not see it.
我觉得应该在something后加was,we heard the sound of something was running,........这样的话be doing组成现在进行时态,请问对不???

Answer 1

1.over是通过某物上方的意思，over his shoulder 本意就是视线从肩膀上方越过去。
2.不可以。running在这里不是表示进行时态，而是作为一个具有形容词性质的动名词来修饰something，其实就可以把它当做一个形容词来看。

Answer 2

1.字面上是"越过他的肩膀看",不就是回头看嘛
2.running是run的过去分词，这里在something后加running是用过去分词短语做定语来修饰something，意思是“正在跑的东西”。 如果用进行时也可以不过应改为we heard the sound of something that/which was running主语不能省略

Answer 3

直译是在肩膀上面看
也就是回头看的意思
hear sb/sth doing 听见某人或某物在做什么
是现在分词做宾语补足语，不能加be

Answer 4

第一个回头看，第二个不对，heard听到的是正在发生的事，是谓语，was也是，否则两个谓语
