四道关于初三英语宾语从句的题目
1Catherine said that she ___ to Guangzhou
A has never gone B had never gone c has never been D had never been
2She asked Linda if __ go and get some
A could she B she could C she can D she may
3She did not know ___back soon
A whether B where C what D when
4They do not know _____their parents are
A that B what C why D which
第一题感觉语境不明 C D都行
第二题是根据宾语从句前后动词时态一致 但是感觉上用C更合适
第三题也是和第二题类似的疑问
第四题是题目错了还是这是句省略句 又或者是WHICH也能配合复数
