Professor: Doug and Liz are at a supermarket buying food to cook for dinner. In the last episodethey ate a lot of fast food, so now they want to buy some healthy organic food. MC: 不过，professor Bowman, organic food--有机食品价格比较贵，不知道Doug和Liz舍不舍得买。 Professor: Let's listen and find out. Liz: Alright Doug, first we need to buy some produce. What kinds of fruits and vegetables shouldwe get? Doug: Wow, look how big those oranges are! Let's get some of those. Liz: No let's not get those. They put all kinds of artificial things into them to make them grow thatbig. Let's get some organic ones. Doug: But the organic ones are much smaller and more expensive. Liz: Doug, it's worth it to pay more for healthy food. Doug想买那些又圆又大的橙子，可Liz说，这些橙子是人工助长的，不健康，她想买纯天然的有机食品。对了，Professor, 什么是produce? Professor: "Produce" is a general word for fruits and vegetables. If you go to a store andwant to buy fruits and vegetables, you can ask where the produce section is. 我明白了，produce就是蔬菜水果这些农产品。 Liz: Alright, next we have to go to the dairy section. We need milk and cheese. |
