Where shall we meet? 我们在哪儿碰头, b. Shall we have any classes tomorrow?明天我们有课吗, 在这类问句中，近年来也有不少人用will，特别是在美国。,]例如: How will I get there? 我怎么去, be going to+动词原形 a.表示打算、准备做的事。例如: We are going to put up a building here.我们打算在这里盖一座 楼。 How are you going to spend your holidays?假期你准备怎样过, b. 表示即将发生或肯定要发生的事。例如: I think it is going to snow. 我看要下雪了。 There‘s going to be a lot of trouble about this. 这事肯定会有很 多麻烦。 c.―will‖句型与―be going to‖句型，前者表示纯粹将来， 后者表示打算、计划、准备做的事情，更强调主语的主观意愿。例如: Tomorrow will be Saturday. 明天是周六了。 We are going to visit Paris this summer.今年夏天我们打算游览 巴黎。 一、单项选择。 1.

It‘s going to rain. 看那些乌云，要下雨了。 I will be twenty-two years old next year. 明年我就22岁了。 Key: ?. 1-5 ACDDB 6-10 BAABB ?. 1. happened 2. will be 3. have; will be 4. said; would try 5. stops 6. works 7. was having 8. belongs 9. finishes 10. had worked ?. 1. called 2. not to know 3. is sung 4. had; got 5. to go 6. sang 7. was 8. working 9. met 10. can‘t help 1. looked 2. to know 3. have thought 4. to live 5. have done 6.
