很高兴为你解答.
保证正确率~!
正确答案是：B
【解析】：
So far the construction of the two new bridges over the river 【has been completed】.
目前为止,河上的两座新桥修建已经完工了.
so far 与完成时态连用,而建筑和完工存在被动关系.
另外,句子真正的主语是 construction ,故用单数,选B.
做这类题目,首先要明确句子的主语是哪个,哪些是修饰主语的.
如果你分辨不来,就尝试翻译,找到你翻译的句子里面的中心,你就明白了.
主要要翻译出来的意思,才能确定句子的真正主语.
祝开心~!
1. construction of the two new bridges 这是句子的主语，当成一个整体看，所以看是单数。
2.so far 开始的句型，不用倒装，所以选B.
欢迎继续提问。
选B
the construction has been completed
