Question

一道高中英语选择题：______ doesn't seem to have been much difficulty in solving the problem

是填He 还是 It 为什么？

Answer 1

it，这是固定句式

追问

那有sb+seem 的用法吗？

追答

不定式 sb/sth seem(s) to do如 I seemed to hear a voice in the distance .
seem+名词 如 She seems a clever girl.
seem +形容词 如 She seems quite happy today.
seem常用于it作形式主语的“It seems/seemed that……”结构，如 It seems that you were lying.
seem有时也同人称代词I连用，意为“感到好像、觉得似乎”等意，如 I seem unable to solve it right now.

追问

根据您的第一行 为啥我感觉题目里该填he呢？

追答

________ doesn’t seem to have been much difficulty in solving the problem.
A. It B. That C. There D. He
C

解析:

这是There be句型一种比较复杂的表现形式，由下列各句逐步形成：
There is much difficulty in solving the problem.
There seems to be much difficulty in solving the problem.
There seems to have been much difficulty in solving the problem.
There doesn’t seem to have been much difficulty in solving the problem.
E.g. There used to be a big tree in front of the old house.
There happened to be a foreign teacher there.
There is said to be no life on the moon.
There must have been something wrong with the machine.

刚刚答错了不好意思，差点误人子弟

追问

这个句型的话为啥中间要有have 呢 那不是还关系到时态了？

追答

have much trouble/difficulty in sth/doing sth.
这个是固定结构
主语+ have +(修饰语：no, little, some, much, great)等+difficulty;trouble +in + doing sth.”是一个常用的句型

Answer 2

It 根据seem的用法

追问

您好，为什么不能用sb 做主语呢？
