The teacher asked Simon if/ whether his sister got up early.
The boy said (that) he needed some English magazines.
宾语从句时态一致就是说从句的时态要和主句保持基本一致。比如这两个例句里主句都用了一般过去时,所以在改写从句时也应由原先的一般现在时改成一般过去时。
若把这两个题目改写下,改成: The teacher asks Simon, "Does your sister get up early?"那么相应的宾语从句也应改成:The teacher asks Simon if/ whether his sister gets up early.第二个例句也同理。
此外请注意人称也要相应改变哦。
