—Is Tom still in New York or already back at home? —I’m not sure _________. I’ll call to make sure. A．if he has been back B．that he has come back C．why he has come back D．how he will be back

Answer 1

A

试题分析: 句意：汤姆还在纽约还是已经回国了？我不确定是否他已经回来了。我会打电话确认的。if he has been back是否他已经回来了， that he has come back他已经回来了，why he has come back为什么他已经回来了，how he will be back他将怎么回来；根据not sure不确定，可知选A。
