整個(gè)括號(hào)里是said的賓語(yǔ)從句.賓語(yǔ)從句里面除非是個(gè)并列復(fù)合句,否則不必把that再重寫(xiě)一遍.比如：
(1) He said,"I am a student and John is my teacher." 改為間接引語(yǔ)后,賓語(yǔ)從句里是個(gè)and連接的并列復(fù)合句,需要多加一個(gè)that:
He said that he was a student and that John was his teacher.
(2) He said,"if I am a student,John will be my teacher." 改為間接引語(yǔ)后,賓語(yǔ)從句里是個(gè)帶條件狀語(yǔ)從句的主從復(fù)合句,不多加that:
He said that if he was a student,John would be his teacher.
因此本題中的前兩個(gè)選項(xiàng)都多寫(xiě)添了that,而C選項(xiàng)一個(gè)that也沒(méi)有,實(shí)際上是省略了he之前的那個(gè),那是賓語(yǔ)從句的標(biāo)志,是可以省略的.所以C正確.
