cognitive stimulation standpoint, we can reduce …其中both和 and连接两个观点,那个as well as作者看样子想拿来当cognitive stimulation standpoint的定语,但我觉得他放错了,老师们怎么认为呢?
1. The moment he has arrived, I will let you know.2. The momnet he arrives, I will let you know.通常遇到第2句的情况比较多,请问老师第1句这样的用法和第二句有什么意思上的区别吗?“他一来我就告诉你。”第1句是强调他一到就告诉你?
