Tapescript

Girl: Life must have been difficult when you were a kid.

Woman: Oh, not really. Why do you say that?

Woman: Of course we did! How old do you think I am? The telephone was invented in 1876.

Girl: 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.

Girl: 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. But in those days, TVs were really expensive, and we couldn’t afford one.

Girl: 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 calculator were invented in 1971 and personal computers were invented in 1976.

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

The things in the pictures were invented in the following order.

The telephone was invented in 1876. Cars were invented in 1885. The TV was invented around 1927. The hand-held calculator were invented in 1971. The personal computers were invented in 1976.

Now you are going to read the listening tapescript. Blacken the passive voice, circle all the linking words and underline all the useful expressions.
