根據(jù)短文內(nèi)容，完成句子。

Travel can teach kids more than a textbook. Travelling with kids is good for them. They can find new interests. Travel makes information alive for kids, and makes it much more exciting than studying textbooks or doing experiments in the laboratory. While travelling, they learn how to deal with new situations, and communicate with other people. They learn patience, because sometimes it takes a long time to get to some exciting or interesting places.

I’ve been travelling since I was seven years old. For me, to stop travelling would be like taking something away from my soul（靈魂）. I can’t live without travelling. Some people think it’s hard to travel after having kids. But in my opinion, when people become parents, it doesn’t mean they can’t travel any more. My children have been travelling since they were three weeks old.

Bringing a new life into the world comes with many responsibilities（責任）and I’d love to be a good mother. One of my duties is to educate my children. I’m so thankful that my parents took me on family trips when I was young. I’ve learned that the outside world is more colorful than the little one I was living in. Of course, I want to pass these travel experiences on to my children.

I value the memories I have travelling with my children. I’m sure they will always remember them in their lives.
