Where and when are they going to meet?
seven o' clock 对应的是When,outside the school gate 对应的是Where,所以这么说.
当然都这种说法,英语的说法多了,这就是在问时间和地点,没错呀!这可是常用的,不要忽视.
对补充:
也可以是When and where are,因为上面的句子是seven 'o clock at the school gate,而when 对应seven 'o clock,at the school gate 对应Where,正好是相对应的,比较符合常理.这么多够了吧!赶紧采纳某人的吧!
