    Richard is our foreign teacher，who is from England.He has the interesting way to make his classes attractive and lively.For example，in last Friday，when he explained the meaning of "crawl" to us，he did not just tell us that it meant in the dictionary.Instead，he lay on his stomach and move forward on his hands and knees slowly.They watched him with interest，laughed loudly.Thus we learnt the word very easy.Richard can speak some Chinese，and his pronunciation is not good.He often asks us correct his mistakes.Have you heard of a teacher who learns from student？Richard does!
