【考点】天气与气候．

【答案】Dear Jim，
    I'm very glad that you will come to visit China.You asked me about the weather in China．There are four seasons---spring，summer，autumn and winter．Summer is the hottest season of the year．It often rains．And winter is the coldest．Sometimes it snows，especially in the north of China．If you like snow，you can come at this time of year．But I think the best time to visit China is in spring or autumn because the weather is not cold or hot．It's very pleasant to visit many places of interest in China，such as the Great Wall，the West Lake，Mount Tai．
I hope you can come soon．
Yours，
Li Hua
