She said that she had just arrived by train.
主句said是一般過(guò)去時(shí),那么從句也要改為從屬于過(guò)去的時(shí)態(tài).現(xiàn)在完成時(shí)就要改成過(guò)去完成時(shí).一定正確嗎？你就放心吧。我是英語(yǔ)教師。當(dāng)然，說(shuō)到時(shí)態(tài)問(wèn)題，如果從句說(shuō)的是客觀真理，那么即使主句是一般過(guò)去時(shí)，從句也應(yīng)當(dāng)是一般現(xiàn)在時(shí)。請(qǐng)問(wèn)尊姓大名？Ah, it's a secret!謝謝您啦！
