托福口语TPO12task6题目 Listening Part:

Listen to part of a lecture in an economics class.

(female professor) So, when we talked about the demand for a product, we’re referring to how much consumers want to buy it, right? And often the demand for a product is influenced by its price, the more expensive it becomes the less chance people want to buy it.

OK, but that’s not the whole story. Sometimes the demand for a product can also be influenced by the price of other related products.

First, there are other products called “substitute goods”. If products can be substituted for one another then, um, well, then they are called substitute goods. They are similar enough to be interchangeable. And, uh, the increase of price of one means the increase for the demand of the other. Like, uh, like butter and margarine. They are pretty much used for the same purposes. Margarine’s butter ’s substitute and you can bake equally well with either. Well, when the price of butter goes up, it becomes less affordable, and so what do people do? They buy margarine instead, right? So, uh, you see, increase of the price of butter increases the demand for margarine.

Now, another instance with the price of one product can influence the demand of another is, uh, is when you have two products that can’t be used without each other.

Those products we call “compliment goods”. They compliment, or complete, each other, if you will. Like compact disks and compact disk players. You need both products in order to use either. So if the price of either product increases demand for both is likely to decrease. And if the price of the CD’s goes up, well, demand for them will do down, right? And because CD’s and CD player compliment each other, what will also happen is that the demand for CD player will go down, too.

Using the points and examples from the talk, explain how substitute goods and compliment goods influence demand for a particular product.

托福口语TPO12task6范文：

In the lecture, the professor talks about how the demand for a product can be affected by the price of another product. When one product is similar enough to replace the other, they are called substitute goods. Take butter and margarine for example, because they are very similar, when the price of either one is increased, the demand of the other would also increase. The second kind of products are called complement goods, which are products that can’t be used without one another. Take the CD player and CDs for example, because you need both products in order to use either, when the price of CDs goes up, the demand for both is likely to decrease, the same happens vise versa.
