英语选择题求解释为什么选a

66. The University of California, _____ in 1868, is administrated by president and governed by a twenty-four-member board of regents.
A. founded B. has been founded C. to have been founded D. was founded

Answer 1

动词原形 过去式 过去分词
find（发现，找到） found found
found（建立，创建） founded founded
本题考查的是非谓语动词，并且答案A选项founded是过去分词，表示被动。即The University of California和found的关系是被动关系。_____ in 1868，这部分是非谓语动词中的过去分词短语。founded in 1868这个过去分词短语在句子中相当于一个定语从句，即which（此句前面有逗号，不能用that） was founded in 1868,
定语从句可分为两大类，限制性定语从句和非限制性定语从句。两者很明显的区别就是非限制性定语从句前面有个逗号，除此之外，定语从句删掉句子不完整，意思发生改变；而非限制性定语从句是可以删掉的，不影响整个句子的完整，起补充说明的作用。
注意：非限制性定语从句一定不能用that用引导词，是不允许。
下面的都是正确的。
The University of California, founded in 1868, is administrated by ...
The University of California, which was founded in 1868, is administrated...
The University of California that was founded in 1868, is administrated...
The University of California which in 1868, is administrated by ...

Answer 2

founded in 1868

这部分是做The University of California的定语

完整的应该这么说：
The University of California（that was founded in 1868,) is administrated by president and governed by a twenty-four-member board of regents.

看到吗？我用括号分割出来了
通常作定语的that was 都会省略

Answer 3

这是which引导的定语从句，which was founded in 1868.因为主语是前面的university，所以省略了which was，用founded 做后置定语。

Answer 4

found是创办，创建的意思，是一个规则变化的动词。
在句中，用A.founded过去分词短语作定语，它相当于一个定语从句which was founded in 1868.

Answer 5

设空所在的句子在整句话中作状语，BD两项是谓语而句中有谓语成分，所以排除BD两项
C表示动作从过去开始延续，一直持续到现在并可能持续下去。跟句意不符，A是用动词过去分词作状语，修饰California大学。
