Question

Could you tell us      ?
About two weeks.
A how long are we going to be away 
B. how often we are going to be away
C. how long we are going to be away
D. how much we are going to be away

Answer 1

C

试题分析：句意：你能告诉我们要离开多久？大约两周。句中所缺是宾语从句，宾语从句要用陈述语序，故排除A；how often多久一次；how long 多长；how much多少；结合语境故选C。
