Dear Bill,

        1      (问候) from Shanghai!

     I am visiting Shanghai these days. It is a beautiful city in the    2     (东方) of China. It is     3    (著名)

for the Oriental Pearl Tower. Every year, millions of      4      (外国的) visitors are attracted to visit it.

Now, I'm      5     (呆) in the hotel and writing this     6     (明信片) to you. This afternoon, I'm going to

do some    7      (观光) and take     8     (许多) of photos. Tomorrow I'm going to get up     9     (早) to

the Bund. It's a road next to Huangpu   10     (江). It's about 1.5 kilometres long. I'm really looking

forward to it.
