答案

1. It's very hot outside,but the classroom is quite cool because it's________
A air conditioned B air condition C air- conditioner D air -conditioned
答：先改题中一小错.class-->classroom. 选择D
译：外面很热,可教室却很凉爽,因为里面有空调.
析：it指the classroom (class指班级,则cool为很酷,不通）.
air-conditioner是空调机,是名词.
air-conditioned是 装有空气调节机的

译：这几天天气变化无常.
