可以用Admission,也可以再Admission前加the表特指,（The）admission to the school 做句子的主语,is是谓语动词,该句译为 只有通过入学考试才能进入该学校.admissionto the school那么这叫什么做主语？短语吗这个就是名词短语作主语，类似的还有动名词短语作主语，比如：Reading in the sun is bad for our eyes.在阳光下看书对眼睛不好，其中reading in the sun就是动名词短语，还有疑问词+不定式短语作主语，比如：What to meet him is not decided yet. 还没决定好什么时候见他。其中What to meet him 也做主语~~
