四、Jim计划暑假来北京游玩，并提前给Mike打电话咨询相关事宜。他们都说了什么？选择合适的句子补全对话。
Jim:Hello! May I speak to Mike, please?
Mike:Hello! This is Mike speaking. 1.
Jim:Hi, Mike! It's Jim. I'm calling from Canada.
Mike:It's glad to hear from you.
Jim:2. What's the weather like in Beijing?
Mike:3. It doesn't rain now, but we'll get lots of rain in July and August.
Jim:I'm coming early next month, and 4.
Mike:So you'll spend most of your summer here.
Jim:Yes. I'd like to see different places in China.
Mike:5. We can go swimming and hiking together.
A. Who is calling?
B. I'm going to stay in China for about six weeks.
C. I'm going to visit Beng.
D. It will be nice to see you again.
E. It's sunny and windy sometimes.

1. A 2. C 3. E 4. B 5. D

我们逐空结合对话逻辑分析：
1. Mike接起电话做完自我介绍后，后文Jim回答自己是谁，说明此处Mike是在询问来电者身份，选A选项“Who is calling?”。
2. 空后Jim紧接着询问北京的天气，结合对话开头Jim计划来北京游玩的背景，此处是Jim说明自己打算来北京游玩，顺理成章咨询天气，选C选项“I'm going to visit Beijing.”。
3. 空前的问句是询问北京的天气如何，此处需要回答天气状况，和后文“现在不下雨，但是七八月会有很多降雨”的内容衔接，选E选项“It's sunny and windy sometimes.”。
4. 空后Mike说“所以你夏天的大部分时间都会在这里度过”，说明Jim此处是说明自己要在中国停留的时长，选B选项“I'm going to stay in China for about six weeks.”。
5. 空后Mike说他们可以一起游泳、远足，说明此处Mike表达再次见到Jim的愉悦心情，选D选项“It will be nice to see you again.”。
