If the flower had been watered,it __as it is.A.wouldn't be B.wouldn't have beenIf the flower had been watered,it __as it is.A.wouldn't be B.wouldn't have been C.would be not D.would have not been 正确答案选A,我选的B.我想问下A和B的区别和选A的原因

A.wouldn't be

A.wouldn't be 意思是：如果当时花被浇过，就不会想这个样子。前面是对过去的虚拟，后面是对现在的虚拟。

看看下面的句子,你就懂了;
1 If he had worked hard 30 years ago,he would have become very rich.
(这一句讲的都是过去的事情,与“现在”没有联系)------这叫单一虚拟语气句子
==He didn't work hard 30 years ago,so he didn't become very rich.
2 If he had worked hard 30 years ago,he would be very rich today
（这一句叫多重虚拟语气句,因为它含有两种不同的虚拟语气.他过去没有努力赚钱,所以他今天不富有.------“过去”与“现在”互相联系着.）
=== He isn't very rich taday because he didn't work hard 30 years ago.
你的句子也是这个原理：
If the flower had been watered,it wouldn't be daed as it is now.
== The flower is dead now because it wasn't watered.
明白了吗?

同意楼上的说法，如果你选B的话，句子应该改为：If the flower had been watered , it wouldn't have been like this. 而原句的主句后面有as it is, 就说明是对现在的虚拟，而B选项表示的是过去的虚拟。
