I have just come to England for half a year and can't speak English. My classmates treat me like a fool. What should I do?

Hehe, this is not a problem. As long as you dare to speak and are not afraid of making mistakes, there is no problem. Really can't. Just let your friends do translation, communicate for a while, eliminate misunderstandings and build confidence. In fact, the British are very nice, very gentleman, polite and will not laugh at people easily. The key is to be 100% confident under any circumstances. Confidence is very important. Of course, with 100% modesty and elegance, you are a nearly perfect person!
