John isn't a diligent student, for it is the third time he has been late, _isn't it_?
原句中文意思是：“約翰不是一個(gè)勤奮的學(xué)生,因?yàn)檫@是他第三次遲到,對(duì)嗎?”
此題考查反意疑問句.for “因?yàn)椤?起補(bǔ)充說明的作用,連接并列句,不是原因狀語從句.反意疑問部分應(yīng)當(dāng)與后一個(gè)并列分句保持一致.it is the third 是后面并列句的主句,疑問部分由它決定,所以空格上填 isn't he.至于 he has been late 這一部分,它是一個(gè)從句,我認(rèn)為它是定語從句,對(duì)疑問部分沒有影響.
但愿你能理解.
