W: By saving water. M: Well, how can we do that? W: By not using too much water when we wash dishes, take a bath, and when we do other things like watering the plants outside. M: Oh, what else? W: When drinking or eating something outside, you should keep the garbage until you rind a garbage can to put it in. Because throwing rubbish carelessly makes our planet dirty, Do you like seeing rubbish all over the ground? M: No, I don't. Do you have any other suggestions? W: Yes, we shouldn't waste paper, because trees are being cut down to make paper. By saving paper, we save the forests where animals live. M: So how can children save paper? I mean everyday. W: Well, for example, when I was in kindergarten, I used to save newspapers so that I could fold things out of them like paper trees instead of just throwing them away. Now the children in our neighborhood collect newspapers once a month to take them to a factory as raw material. M: That's great. Well, thanks Catherine for your ideas.

W: Well, it would be nice to get away from this cold weather and just lie in the sun and relax after working so hard. M: It's true that skiing does require work. And you have to get up early and wait in long lines for the chair lifts. Thanks. I think you help me make up my mind. W: Sure. Now maybe you can use your mind to think about something else, like your studies. M: Yeah, just as you said, I should focus more on study now, because the exams of various courses are approaching. If I cannot pass those exams smoothly, I will not have a good time in vacation. W: Absolutely! So now we should put the vacation aside temporarily and make good preparation for the exams.
