4、先，我们将本模块中出现的有代表性的句子归纳如下：时态例句一般现在时(1)And I think the Three Gorges Dam is fantastic too.(2)It produces electricity for millions of people in China.一般过去时(3)Well, I visited the Giants Causeway two years ago.现在进行时(4)Am I going the right way?过去进行时(5)When I arrived, it was early morning and it was raining.
