We have a live-in doctor if there's a problem I can't handle.
假如我遇到不能解决的问题 ,我们还有位驻家医生。
I would like to welcome you once again.
我向你们再次表示欢迎。
Of course he is. He's very successful. He's made lots of records. They broadcast a programme of his music last month on the radio. Why don't you come on Saturday? I think you'd enjoy it.
