二、阅读理解：阅读下面的短文，根据文章内容从A、B、C三个选项中选出一个最佳选项。Hi , Joe,
How are you? I'm sitting on the balcony of my hotel. I am looking at Hyde Park in London and I am thinking about my life here. I am having a wonderful time. I like my job –it is very interesting, and my colleagues are great. I love London –it's busy, noisy, crowded and exciting. The cinemas, theatres, pubs and restaurants are really nice, –but they're too expensive! I think the people in London are very friendly (surprise!) and I've got some new friends.
What the weather like in Shanghai? Is it raining? Here it's lovely! It isn't foggy! The sun is shining and the birds are singing. It's very warm.
And it is my birthday today.
But I am missing you all in Shanghai. COME AND VISIT!
Love,
Xiaoyan
