Question

Lin Tao is so good at German that I'm wondering __________.

A.if he has been to Germany before B.how long has he been to Germany

C.if he has gone to Germany before D.how long has he gone to Germany

Answer

A

【解析】

句意：林涛是那么擅长德语以至于我想知道是否他以前去过德国。

考查宾语从句的语序和have been to和have gone to的区别。A. if he has been to Germany before是否他以前去过德国，陈述语序； B. how long has he been to Germany他去德国多长时间，疑问语序；C. if he has gone to Germany before是否他到德国去了，陈述语序；D. how long has he gone to Germany他去了德国多长时间，疑问语序。根据句意空处的句子为宾语从句，应是陈述语序，故排除B、D；have been to去过某地；have gone to到某地去了。根据句意应为“是否他以前去过德国”，故选A。
