Notes:
1. To ask someone if they have done something in the past, you can say: Have you been to Beijing before; Have you seen the Great Wall? 如果問某人在過去是否做過某事，你可以說：Have you been to Beijing before? (你以前去過北京嗎？); Have you seen the Great Wall? (你見過長城嗎？).
2. You must know it quite well. You can use this expression you must...when you think something for certain, e.g. after a long busy day: You must be tired. 你一定對它非常了解。當你非常確定某事時，你可以用下面這個表達法：You must...(你一定...), 例如：在某人忙碌了一天之后說：You must be tired (你一定累了)。
