部分听力原文：

M: No, not at all. Oh, (20)the effects were very good.

W: Yes, I thought they were marvelous. Especially the battle in space, incredible.

M: Yes, but I was going to say I thought the acting was terrible.

W: Yes. I suppose Jason was too good to be true. And what was the name of the Baddy?

M: Cargon?

W: Yeah. Cargon was really evil, wasn't he? But I suppose that's what these films are all about-good triumphing over evil. (21)And the characters have to be black and white.

M: Well ,yes, but not always. War of the Worlds wasn't like for example. Anyway, you enjoy the film. That's the most important.

W: Yes, I did. Thanks for taking me.

Q:

19. What does the man say about the science fiction films?

20. What opinion did the speakers share about the film they just seen?

21. What to be learned about Jason and Cargon?

解析：实际听题过程中，20题极易被考生选D选项，因为21题答案句中的characters这个词，而21题又极易被考生选B选项，因为原文中划双下划线的War of the Worlds.

在以上这两个原文相对较难的题型中，对于大多数基础不是很扎实的同学来说，只听一遍是不太可能听懂大意和之后的问题的，所以就要求大家尽可能按照上文讲的方法去练自己迅速反应过来单词被读到的能力。万不得已的情况下，通过以上听力原文大家不难看出，干扰选项大多出现在正确答案之后的位置，所以如果在听到两个选项又不敢确定的情况下，选择先听到的可能更容易做对。
