choose A?

_ for your laziness, you could have finished the assignment by now.(A) Had it not been (B) It were not (C) Weren't it (D) Had not it been
A. Had it not been 如果不是因为

不用if 的虚拟语气的倒装强调，选择A。

是的，这是一个省略了 "if" 的第三种情况式。在英语中，有时省略 "if" 是很常见的，特别是在口语或非正式的写作中。因此， "Had it not been for your laziness, you could have finished the assignment by now." 和 "If it had not been for your laziness, you could have finished the assignment by now." 意思是相同的。
