术(选择)(选择)
解题思路: 选择
解题过程:
1.答案:B 句子的真正主语是each of the students,横线处填的hopes是句子谓语,其中的working hard at his or her lessons是插入句中修饰主语的非限制性定语。
当either(each, one)+of+复数名词,或some, any, no, every和body, one或thing构成复合不定代词作主语时,谓语动词用单数形式。none, neither作主语时,谓语动词单复数形式都可。
2.答案:C each of the students是句子主语,横线处为句子谓语,hoping to pass the exam是修饰句子主语的非限制性定语。题中其他选项都是非谓语动词的构成形式,不能充当谓语成分,因此都不能选。
最终答案:略
