It is very important for us to start with a low-carbon lifestyle. But how can we live a low carbon life? Here are my ideas.Firstly，it is a very good idea for us to go to school on foot instead of by car. It is good for the environment and our health as well. Secondly，remember to turn off the lights，fans and computers when we leave the classrooms. Thirdly，it is important for us to turn off the tap when we finish using the water. We can reuse water，too. For example，we can reuse the water to water the flowers or trees. At last，try to use the cloth shopping bags instead of plastic bags when we go shopping.

Travelling with kids is good f 1 them. They can find new interests. Travel makes information alive for kids, and makes it much more exciting than studying textbooks or d 2 experiments in the lab. While traveling, they learn h 3 to deal with new situations, and communicate with other people. They learn patience, because sometimes i 4 takes a long time to get to some exciting or interesting places.I’ve been traveling since I was seven years old. For me, to stop traveling would be like taking something a 5 from my soul（灵魂）. I can’t live without traveling and I wouldn’t be who I am if I don’t travel. Some people think it’s h 6 to travel after having kids. But in my opinion, when people become parents, it doesn’t m7 they couldn’t travel any more. My children have been traveling since they were three weeks old.Bringing a new life into the world comes with many responsibilities（责任）and I’d love to be a good mother. One of my duties is to e 8 my children. I’m so thankful that my parents took me on family trips when I was y 9 .I’ve learned that the outside world is more colorfu l than the little one I was living in. Of course, I want to pass these travel e 10 on to my children.I value the memories I have traveling with my children. I’m sure they will always remember them in their lives.1. 2. 3. 4. 5.6. 7. 8. 9. 10.1When his friend Bob saw him, he laughed and said, "What has 2 to your hair, Jack?"Jack said, "I tried a new barber's shop today, because I wasn't quite satisfied(满意的) with my 3 one, but this one seems even 4 ."Bob agreed. "Yes, I think you're right, Jack. Now I'll tell you 5 to do when you go into a barber's shop next time: look at all the barber's hair, find out 6 hair looks worst, and then go straight to him.""Why shall I go to him?" Jack asked. "But that would be foolish!""Oh, no, it wouldn't," answered Bob. "Who 7 that man's hair? Just think it. He couldn't cut it 8 , could he? Another of the barbers cut it. So you know he can't be the worst barber."1. 2. 3. 4. 5. 6. 7. 8.六.书面表达我们知道，由于环境污染、人类的残杀，很多野生动物濒临灭绝。
