语法检查
自从学了GMAT以后,都不敢写英文了...今天写一个句子想了半天,请帮我看看怎么写才是对的~还是全都是对的~
A.The company remained some wages payable did not pay to its workers at the end of 2012.
B.The company remained some wages payable,which the company did not pay to its workers at the end of 2012.
C.The company remained some wages payable,which were not paid to its workers at the end of 2012.
要是是学GMAT以前,我会毫不犹豫地写A,但是现在只敢写C了,
到底ABC这三种写法是不是都是对的?
