英文小作文：

Free trade has always been a hot topic in today"s world. It means that goods and services can freely move between countries without any restrictions or barriers. In this way, people can buy goods from other countries at lower prices and sell their products to other countries at higher prices, which creates more opportunities for businesses and creates wealth for all.

However, some people are skeptical about free trade because they think that it will cause some problems such as job losses and income inequality. But if we look at it from a broader perspective, free trade can also bring about positive changes such as increased economic growth and better living standards for everyone.

In conclusion, free trade is a win-win situation for everyone involved, but it requires a fair and open playing field to ensure that everyone benefits equally from it. We should encourage free market principles and encourage businesses to compete fairly to create a better world for all of us.
