  12. Tapescript Alice: Life must have been difficult when you were a kid. Woman: Oh, not really. Why do you say that? Alice: Well, you didn’t have many modern inventions. Like, you probably didn’t have a telephone, right? Woman: Of course we did! How old do you think I am? the telephone was invented in 1876.

  13. Alice: How about cars? I bet cars weren’t invented yet. Woman: Sure they were. Cars were invented in 1885. My family had a car. I think you need to take a history class, Alice. Alice: Ha, ha! Well ,did you have a TV? Woman: No, We didn’t. The TV was invented around 1927, I think. Some friends of mine had one.

  14. But in those days, TVs were really expensive, and we couldn’t afford one. Alice: And I bet you didn’t have calculators and computers and stuff. That’s something I do know. We learned in school that hand-held calculators were invented in 1971 and personal computers were invented in 1976.

  15. Woman: You are right. I didn’t have those things when I was young. But I do now!

  16. Pairwork (1c:P68) Sample dialogues: A: When was the telephone invented? B: I think it was invented in 1876. A: When was the car invented? B: I think it was invented in 1930. I think it was invented after the telephone.

  17. C: I don’t think so. I think it was invented in 1873, so it was invented before the telephone. D: I don’t agree. I think it was invented in 1885 and it was invented after the telephone.

Girl: Julie Thompson. And look at this heated ice cream scoop. Boy: I know what it’s for! It’s used for scooping out really cold ice cream.

  21. Girl: Right. It was invented by Chelsea Lanmon. Boy: My favorite are those shoes with adjustable heels. You know- you can move the heels up and down. They were invented by Jayce Coziar and Jamie Ellsworth. Girl: And what are they used for? Boy: Well, you can change the style of your shoes. You can make the shoes go from casual to dressy.

  22. Oral Practice (2c: P69) Sentence pattern: What is it / are they used for? Who was it / were they invented by? It is / They are used for doing... It was / They were invented by ...

  23. Sample dialogues: A: What is this? B: This is a heated ice cream scoop. A: What is it used for? B: It is used for scooping really cold ice cream. A: Who was it invented by? B: It was invented by Chelsea Lanmon.

  24. Grammar Focus (P69) The passive voice 被动语态 在被动语态的句子中, 谓语部分的结构是be + 过去分词。被动语态的句子的时态变化反映在be动词上。也就是说, 把一个句子做成被动语态的句子, 只需要写出be动词的所需时态, 再加上所给动词的过去分词就行了。

  25. 当然, 这只是指谓语部分而言。我们知道, be动词作为一个独立的谓语动词有自己现在分词(being)和过去分词 (been)。那么, 下面我们来看看be 在各种时态中的变化形式：

  26. 一般现在时 am / is / are 一般过去时 was / were 一般将来时 shall / will + be 过去将来时 would / should + be 现在进行时 am / is / are + being 过去进行时 was / were + being 现在完成时 have / has + been 过去完成时 had + been
