Conversation 2

Man: Hey, what are you reading?
Woman: I'm reading how cows contribute to climate change.
Man: Cows! How do they do that?
Woman: By releasing methane gas into the environment.
Man: But, they're cows! I don't see how they can do that.
Woman: They release gas by burping. It says cows burp a lot.
Man: By burping? How strange.
Woman: It also says that farmers cause damage by cutting down trees to make farmland.
Man: Yes, I've heard about that. Cutting down trees does damage by reducing how much trees can absorb CO2.
Woman: Yes, and deforestation is also a problem by causing soil erosion.
Man: So, what can we do about it?
Woman: I suppose that we could help by eating less beef.
Man: Yeah, or we could help by buying meat from local organic farms.
Woman: Sounds good. Time to put our best foot forward.
Man: Yes, and to put our money where our mouth is, literally.

Conversation 3

Man: So, what are you doing?
Woman: I'm studying Japanese by watching videos on Netflix.
Man: That's interesting, but it must be difficult.
Woman: It is, but I can follow along by reading the captions.
Man: Oh, do you mean the English subtitles?
Woman: No, the captions. I hear it and read the Japanese text simultaneously. By doing so, I can catch a lot.
Man: That sounds like a good strategy. I should try that to learn French.
Woman: Oh, you are learning French?
Man: Yes, but just by using some vocabulary apps on my phone.
Woman: Well, you might learn more by checking out some videos online. There's lots on YouTube.
Man: Or by using your Netflix account.
Woman: Not a chance. Nice try though.
Man: Well, no one ever got anything by not asking.
Woman: True. I'll give you that.

Conversation 4

Woman: How do you like your food?
Man: It's good, but I'm not used to eating vegetarian food.
Woman: You should become vegetarian. There are many health benefits by doing so.
Man: Yes, that's true, but I love eating meat. It tastes so good.
Woman: I understand, but by changing your diet, you can explore lots of new dishes.
Man: Yeah, I know, but I work out a lot. And I am afraid that by giving up meat, I'll lose lots of key nutrients.
Woman: I assume you are referring to protein? Well, just by eating beans and nuts you can get all the protein you need.
Man: Perhaps, but I also worry about missing out at social gatherings, like barbecues, picnics and parties.
Woman: Yes, I see your point, but by being a vegetarian, you open yourself to new social situations.
Man: Yeah, I guess you're right. I will give it some thought.
Woman: Take your time. Rome wasn't built in a day, as they say.
