但我觉得a 也对 80.----- seems no need to hurry.A.It B.That C.There

如果用It,得这样说:
It seems that there's no need to hurry.
实际上,that 后也可以接seem,
That seems to me one way of dealing with inquiries about telephone numbers.
为什么选There ,而不选it 或that,而选there,
There seems no need to hurry,类似 There is no need to hurry.句子结构完整,意义明确.
It seems no need.关键在于seems 之后这里接的是 need,名词.既然是名词,就有是否存在的概念.it 这里,做虚主语/形式主语/或者代表一个情况,无法表示是否存在这个意义.逻辑上,语法上都说不通.
如果,seem 后接形容词,则说得通,如,need 换成形容词necessay,则有以下句子:
It seems no necessary to hurry.(情况)看起来,(是)没有必要匆忙.
也就是说,
对于名词need,要理解为:有必要,没有必要.所以,there is ...,there seem ...不能It seem no need.It is no need.
对于形容词necessary ,要理解为:是必要的,不是必要的.It seems,It is ,同样,不能there seem no necessary...
