理工类辅导资料：时态的感情色彩
进行态除了表示一个进行的动作以外，更多的是带有一种“态”，也就是说有一种情态在里面。注意下面句子的比较：
· More and more people buy TV sets.
· More and more people are buying TV sets.
越来越多的人买电视机。
注第一句话只是说出一个现象，第二句话却给了我们一个生动的画面，试图让我们看到人们购买电视机的情景。
It rained下雨. It was raining.
Th girl cried哭. The girl was crying.
-------- I had very good seat. The play was very interesting. I did not enjoy it. A young man and a young woman were sitting behind me. They were talking loudly.
· Do you know your wife was having dinner with a guy in the restaurant near our school yesterday evening?
你知道不知道你的老婆昨天晚上和一个小伙子在学校附近的餐馆一起吃饭？
注：说话的人没有用一般过去时，而是用过去进行时态。从这句话
中可以看出他通过进行时态的画面感，给对方一个亲眼看到的感觉，以刺激听话的人。
▲ 将来进行时态
· I will wait等待for you at the airport.
· I will be waiting for you at the airport.
第一句用的是一般将来时态，第二句用的是将来进行时态。第二句给人的感觉好像能够看到说话的人将在机场等待的情景，所以更亲切、更踏实。这就是画面感的效果。我们很难用汉语表达出上面两句话的不同。
It rained. It was raining.
