A、Global warming. B、Environmentally conscious. C、Physical health. D、A hybrid car. B在对话中开头虽然提到全球变暖，但整篇对话围绕环保意识展开，女士分别举出垃圾回收和她购买的更

M: So, you are pretty in tune with global warming. (15) You are pretty in tune with the environmentally conscious. What do you do to do your part for helping protect the environment?
W: Yeah, well, I think I do quite a bit. (12)I grew up in an area that’s really environmentally conscious. Oregon is pretty environmentally conscious, (13)so I recycle. It’s pretty easy to recycle in Oregon. They just pick it right up at your house. You don’t have to separate it. They separate it for you, so I recycle as much as I possibly can.
M: But maybe those are traditional things. Do you do anything sort of more advanced or more modem than just recycling?
W: Well, one thing: (13) I recently bought a hybrid car.
M: A hybrid car.
W: Yeah.
M: What’s a hybrid car?
W: So (14)it is a car that basically gets better gas mileage because what my car does is I have to put gas in it. I have to put gas in it but (14) when I break it takes the energy created by the heat from the breaking and it charges the battery, and then the battery can help power the car, so (13) it’ s half gasoline, half-just electric energy from the battery.
M: Really. Electric and gas.
W: Yeah.
M: Really interesting. So do you have to charge the car at night? Do you have to plug it in or anything like that?
W: No, my car just by breaking it charges the battery completely. Occasionally, I’ve heard of some people that if they leave their car for like a year or something they have to go back and (14) they’ll have to plug in the battery and it will charge up, but for the most part I don’ t have to do very much at all.
