在c和e之间纠结，答案是e，但我觉得and前面加了逗号所以，要用it

我在manhattan看到的一句话是：
Wrong：Earl walked to school,and later ate his lunch
Right:     Earl walked to school and later ate his lunch
Right:     Earl walked to school ,and he later ate his lunch.
希望大牛们帮忙解释下，谢谢

这题前几天我也做过，不加it是应为it 和which 不可以指代前面的整件事情，所以加了会出现指代错，而e不加正好与前面的required.....构成并列。你说的那个manhattan是没错可这里是并列的最后一项，必须加and,是你说的Wrong：Earl walked to school,and later ate his lunch
Right:     Earl walked to school and later ate his lunch
Right:     Earl walked to school ,and he later ate his lunch.
的貌似是唯一的例外。

剪切错了，再打一遍。。。。Wrong：Earl walked to school,and later ate his lunch
Right:     Earl walked to school and later ate his lunch
Right:     Earl walked to school ,and he later ate his lunch.
是对的，不过这题是这个规则的一个例外

应该是说并列项最后一项前加and，构成and +v是你规则的唯一例外
