提示：
假设由你接待一组加拿大中学生代表团。该团经广州、成都等地在北京只逗留两天。团长向你征求意见在北京先参观何处，请按以下提示提出你的口头建议：
1、首先建议去长城。长城是世界是最长的墙，是世界八大奇观之一，有20个世纪的悠
久历史，全部由手工建成，令人惊叹不已。
2、其次是故宫，它建于1406年，曾有24位皇帝在那儿居住过。皇帝在那儿发号施令。
参观它，可以更多地了解中国历史。
3、对其逗留时间短暂深感遗憾，否则，可以参观许多具有历史意义的地方和景区，如颐和园、北海公园等。
参考词汇：发号施令：issue orders、令人惊奇：amazing
Well, the first place I suggest that you visit is the Great Wall, the longest wall in the world, which is said to be one of the wonders in the world. It has a history of more than twenty centuries. It is amazing to see such a huge wall was made entirely by hand.
The other place worth visiting is the Palace Museum, which was built in 1406. Twenty-four emperors once lived there. from there the ruling emperors issued orders. You can learn a lot about Chinese history by visiting this Palace.
What a pity that you can't stay longer, otherwise, you could visit many other historic places and beautiful scenes such as Summer Palace, Bei Hai park and so on.
