sat oc 语法题
By the end of the eighteenth century, watchmaking technology had greatly improved, （and they were standard equipment for military personnel.）
(A)and they were standard equipment for military personnel
(B)so it was standard equipment for military personnel to have watches
(C)with watches included in the standard equipment for military personnel
(D)and watches had become standard equipment for military personnel
(E)and for military personnel it was standard equipment
答案是D B哪里错了 it不可以做形式主语吗

sat oc 语法题By the end of the eighteenth century, watchmaking technology had greatly improved, （and they were standard equipment for military personnel.）(A)and they were standard equipment for military personnel (B)so it was standard equipm
把这个句子整理过来,缩句,变成这个样子：
To have watches was standard equipment.
这句话显然是不对的,主语是to have watches,表示“拥有手表”这个动作,而表语则是standard equipment,是一个名词,两者不相匹配.
正确的句子是：
so it was standard for military personnel to have watches as equipment.
况且即使改成这样,也不够简明扼要,sat很注重简洁的,相信这样的答案也不能入选.
至于A、C、E,我想你已经明白了,这里就不做解释,如果不懂可以追问~
