语法好的进来啊`~
为什么用it is 语序为什么不是is it.
Q2:Everyone has seen a frightened dog put his tail between his legs and run in panic.
为什么用了has seen 后又用了put,这不就有两个谓语了吗?还有请问put 做什么成分?最好分析下该句结构.
Q3;怎样区分动词短语和介词短语,有没有相关的一些总结?

Answer 1

1.以上所说的"put 也是个过去分词,在dog 和put之间省略了连接词that"等观点都是不正确的.
Everyone has seen...虽然是完成时态,但是它依然是考察see的用法.
大家都知道,see后面的非谓语动词有三种形式:
1)see + doing 看到某动作正在进行,并且动作没有结束,如:
I can see a bird flying in the sky.我看到天空有只鸟在飞(正在进行)
2)see + done 看到某人或某物被怎么样,如:
I saw Tom punished by his mother yesterday.我昨天看到TOM被他母亲惩罚(被动)
3)see + do 看到某事情的发生,是指完整的看到事情发生的全过程.如:
I saw him get into a taxi.我看着他走进出租车里(整个过程)
因此,在上面问题中,也是属于这地三种用法,"put his tail between his legs and run in panic."都是属于"see + do"结构中do的部分,put是动词原形.
这是考察感官动词后面的非谓语动词,其他类似感官动词还有:hear,listen to,notice,watch,observe,look,see等
2.动词短语通常是"动词(常常是不及物的)+(名词)+介词/副词.如
get up/down/to
come out/up/round/
keep in touch with
介词短语通常是"介词+名词+(介词)"如:
for the sake of
in spite of
regardless of
as a reuslt of..
