As I stuck in the mud (泥), with my bike on top of me, I wondered what had forced me to come here. Madagascar is not a good place for a cycling holiday: one of the world's poorest countries, only 11 percent of roadway is paved (铺). South of the town of Antalaha, where I started, the road was in worse condition.

I appeared from a week in the wilderness and reached the start of the Route National 5 at Maroantsetra, but my dream of a smooth road and speed was suddenly destroyed by mud. The "worst road in the country" changed my bicycle into a burden (负担) for days. Finally, I was claimed by the road. Tired. Alone.

As I wiped (擦) the mud from my face and looked upwards, I was greeted by a Malagasy man. He helped me stand up and smiled playfully while he pointed to my bike, which sat next to his. I started again. But I fell again in the mud. Angrily, I told him to go on, but if he understood he showed no sign of it. His smile forced me back onto the bike. We continued like this for hours. But I fell less. Studying my quick guide, slowly I learned. As we passed through a village, a group of children saw me and shouted loudly. His only words were: "Their parents tell them while people steal and eat them. Funny, no?"

I tried to ask why, but he had already set off. I tried to catch up; as I got closer, he took it as a challenge and sped up. We raced along the road. I rode a little faster and I was just behind, about to catch up with him. With a smile, he sped up and was away, leaving me breathless.

Children’s lives have changed greatly over the last 50 years. But do they have a happier childhood than you or I did?

It’s difficult to look back on one’s own childhood without feeling nostalgic(怀旧的). I have four brothers and sisters, and my memories are all about being with them, playing board games on the living room floor, or spending days in the street with the other neighbourhood children, or racing up and down on our bikes. My parents hardly appear in these memories, except as providers of meals.

These days, in the UK at least, the nature of childhood has changed greatly. Firstly, families are smaller, and there are far more only children. It is common for both parents to work outside the home and there is the feeling that there just isn’t time to bring up a large family, or that no one could possibly afford to have more than one child. As a result, today’s boys and girls spend much of their time alone. Another major change is that youngsters today prefer to spend most of their free time at home, inside. More than anything this is because of the fact that parents worry far more than they used to about real or imagined dangers, so they wouldn’t dream of letting their children play outside by themselves.

Finally, the kind of toys children have and the way they play is totally different. Computer and video games have replaced(取代) the board games and more active pastimes of my childhood. The irony(讽刺) is that so many of these games are called “interactive(互动的)”. The fact that you can play computer games on your own further increases the sense of loneliness felt by many young people today.

Do these changes mean that children today have a less pleasant childhood than I had? I personally believe that they do, but perhaps every generation(一代人) feels exactly the same.
