Question

请问should be to give access to是什么用法？

请问 Those who harbor the view that the main funiction of universities should be to give access to the knowledge believe that the theoretic knowledge is the foundation of any paractical skills. 这句话中 should be to give access to是什么用法？为什么不是should be given access to？改成is to give access to是否可行？

Answer 1

Those 主语
who harbor the view 定语从句 先行词是those
that the main funiction of universities should be to give access to the knowledge view的同位语从句

同位语从句还可以是 To give access to the knowledge should be the main function of universities. 这里是虚拟语气的用法

【注意1】在某些名词(如demand, wish, suggestion, resolution等)后面的同位语从句要用虚拟语气。如：
They were faced with the demand that this tax be abolished. 他们面对废除这个税的要求。
They expressed the wish that she accept the award. 他们表示希望她接受这笔奖金。
There was a suggestion that Brown should be dropped from the team. 有一项建议是布朗应该离队。
The suggestion that the new rule be adopted came from the chairman. 采纳新规则的建议是主席提出的。
The resolution that women be allowed to join the society was carried. 允许妇女参加这个协会的决议通过了。
I can understand their eagerness that you should be the main speaker. 我理解他们希望你作主要发言人的殷切心情。

believe 主句的谓语 相信
that the theoretic knowledge is the foundation of any paractical skills. 宾语从句

原句中should be to give access to是否可以用is to give access to替换？替换后句子还存在三种从句吗？

追答

对不起 我看错了。。。（不是同位语）

这个should 只是一般的用法

可以替换

但是 should be to 和 is to 不同

should be to do 证明大家希望这样做 但是事实还没用

is to 没有希望的暗示 少了很多情感色彩

追问

是同位语从句吧，作文书上说这个句型包含了定语从句、同位语从句和宾语从句。

追答

恩，但是view不一定要虚拟

其实不和should有关

be+to do 是系表结构就够了

追问

嗯嗯，感谢回答，不好意思只能选一个答案。

追答

选我咯

追问

几分钟前就选好了啊。。。

追答

晚安咯

Answer 2

在修饰the view的同位语从句that the main function of universities should be to give access to the knowledge believe that ....中，the main function of universities 是主语；should be是系动词；to give access to .....是表语。类似的语法，给个简单例子看一下：
The task we must fulfill now should be to find the solution to this problem.
若还有其他地方的问题，欢迎追问，乐意帮助。

追问

In sum, the major function of universities shoud be providing most students job-related skills, guaranteeing high rate of employment, and thus making the society function well.这里的should be+V-ing呢？

追答

正确。to do和doing都可作表语

追问

在作文中若将例句改成 The task we must fulfill now is to find the problem's solution. 是否会逊色不少？

追答

两句语气不同而已,看你需要什么语气. be to do表示毫无疑问，不会有什么意外，而“should be"则含有“如果不出呼意料，应该是”的意思
