w: i noticed an article in the newspaper about the problem of rapid growth of cities in america. i was wondering... do you americans carry out a birth control policy? can americans have as many children as they want? 
m: yes, we can have as many as we want, but most people decide to have only one or two. and some people decide not to have any.
w: why do they decide not to have any? in the old days, we chinese always wanted to have as many as possible. some still do now.
m: some people prefer to devote all their energy to their work or to seek their own interests and travel. and others see so many problems in the world that they refuse to bring children into such a difficult environment.
w: it's understandable.

good morning, everyone. today i'd like to give a lecture on cycling tours. well, for anyone who is considering going on a tour, the first thing to consider is safety. so it's very important indeed to consider what you wear. wear something that can easily be seen, red jackets, for example. you know many accidents happen, because drivers simply fail to see the cyclists. second, don't try to ride too far, toe quickly. take your time, and if you feel tired, stop and rest. remember that the joy of cycling tours is the ride itself. get close to nature and see things you wouldn't normally see when you were traveling by car or bus. and if you're planning your journey in the summer, take plenty of water. you are advised to drink at least one liter of water every hour. if the weather is not very warm, make sure you take some warm clothes. and put them on when you stop riding. even in cold weather you can become very warm when you are riding and then it is very easy to catch a cold, or even get a fever when you stop.
