　　Here at Yale（耶鲁）we are very excited because Rui Chenggang has （37）began his blog．Chenggang，who was born in 1977，is very （38）success．As one of his professors，I think that he was a fast learner．We quickly learned that he was also a good teacher．The United States and England are two great（39）country that use a common language．Even though we both speak English，we often mean different things with the same words．He helps the Chinese to understand the American people．

　　His English is（40）very good that he can talk with Americans freely．We couldn't believe he had never lived in the United States before his trip to Yale．He is able to understand both their words（41）or their meanings．When you read his blog，you will know he is translating the meaning，not just the words．
