　　(以下M代表Mary,T代表Tom)

　　M: Hi, Tom! Your pictures are terrific. How long have you been a photographer?

　　T: For about two years. That's the one thing I really enjoy.

　　M: I've just bought a new camera Would you please show me how it works?

　　T: Yes, of course. It's a snap. First of all, you have to make sure the battery has been charged.

　　M: Yes, I charged it yesterday.

　　T: OK. Then let's check the memory card. Umm... it's good. It is necessary to have some space for your pictures. Now everything is ready, you can take a picture. Press this button.

　　(Mary presses the button and takes a photograph)

　　M: That's cool! I succeed. Thank you, Tom!

　　T: Wait a minute. See it carefully. You see? The picture is faint.

　　M: Oh, yes, what's wrong?

　　T: When you take a picture, you must hold the camera steadily without any thrill. It's very import,ant. Now try it again.

　　(Mary follows Tom's words and takes another photograph)

　　M: The penny drops. You're really good at it.

　　T: It's not a big deal. You also have to adjust the lens while using the camera at night.

　　M: I'II remember that. Thank you very much, Tom.

　　T: You're welcome.

　　派生詞的重音

　　所謂派生詞，就是借助前綴和后綴在某一單詞的基礎(chǔ)上構(gòu)成的新單詞，如前綴un-加詞根necessary形成派生詞。派生詞的重音一般和詞根的重音一致，如necessary /?nes?s?r?/，重音在第一個(gè)音節(jié)，其派生詞unnecessary /?n?es?s?r?/和necessarily /?nes?s?r?l?/的重音也都在詞根的第一個(gè)音節(jié)上。但也有些派生詞與詞根的重音不一致。有些名詞派生出來(lái)的形容詞，重音與詞根相比通常會(huì)后移，如：

　　science/?sa??ns/科學(xué)→scientific /sa??n?t?f?k/科學(xué)的。
