the reason is ______he is unable to drive the truck
A because
B why
C that
D whether
这是个什么从句'表语从句还是同位语?
为什么不是why 而是 that

C.这句是表语从句,是明显的主系表结构,is是系动词,the reason 是主语,后面那个部分就是从句.如果是the reason why中间首先不能有is,因为why是紧跟在the reason后面用来引导一个从句来解释这个reason是什么,因此这句话就要变成The reason why he is unable to drive the truck is blalalalal,理解了吗?反正你以后记住,the reason why就是连在一起的,中间绝对不会出现be动词,而且在why引导的从句后应该有一个动词.
再问： ��'лл'�ǲ��thatҲ��
再答： that��壬ֻ��Ӿ��á�
