A、They should be conscientious in the office. B、They should bring some paper cups with them. C、They should start drinking bottle

M: Good morning, Faith. In light of the recent economic downturn, we thought we should think about some ways we can conserve energy.
W:(6 - 1)I think we could easily cut down on "vampire power". Our computers and other electronic devices actually continue to suck power, even when they are switched off.
M: Good one!(6 - 2)The online encyclopedia Wikipedia claims that " vampire power" or "standby power" is responsible for using as much as 10% of electricity consumption.
W: We could unplug the equipment or put in power strips that can completely turn off power.
M: Just imagine, we could save 10% or 15% on our energy bill just by unplugging our computers!
W: And that’s just the beginning! You see these lights above us? These use LED bulbs that are 10 times more efficient than the bulbs you are using in the rest of the office.
M: But they’re pretty pricey, aren’t they?
W:(7)Yes. They cost more, but you’ll find that they pay for themselves.
M: I’ve got one that will require a bit of sacrifice. We really don’t need to use bottled water for meetings. We could also get rid of paper cups for the water cooler and everyone could use their own mug instead.
W: Ah, I love bottled water, but I agree that your idea is certainly more environmentally friendly.
M: Yep. Sometimes going green does require that we change our mindset. It’s funny how many of us are very conscientious at home. We recycle and reuse, but when we get to the office, we sometimes become very wasteful.
W: I’ve recently noticed how much paper I use on a daily basis and I’ve been trying to cut down. I’ve found that I very rarely actually need to print e-mails. Also, by utilizing my faxmodem, I don’t ever need to print a hardcopy for faxing.
M: That’s going to add up! In the end you’ll find it makes a huge positive difference!
W: But you know, even with all these good ideas and strategies, I feel like it counts for nothing when you factor in air travel. Our people make a lot of international trips each year and flying puts tons of CO₂ into the atmosphere.
M: Ah! Good point! Well,(10)for starters, with teleconferencing and instant e-mail one would hope business travel could be reduced.
W: But sometimes there’s just no alternative. We have to check out factories, locations in some countries: you really have to look the person in the eye and physically shake their hand.
M: This is true. Anyway, we’ve got a lot so far. Nice talking with you.
W: Me too. I hope it will help a lot in the future.
M: I’m sure it will.
