So far the construction of the two new bridges over the river ________..have
So far the construction of the two new bridges over the river ________.
A.have been completed B.has been completed
答
B.has been completed.
分析:
句子的主语是the construction,属于抽象名词,视为第三人称单数,所以谓语动词是has been...A of B句型怎么判断谁是主语?通常来说,A是主语。如:the title of the passage (那篇文章的标题)the population of the country (那个国家的人口)a small group of the students(那帮学生的一个小组)one of the passengers (那些乘客中的一个) 但是,有的固定搭配表示“量”,所以中心词是B。如:a number of people (许多人)a lot of flowers (很多花) 可以这样判断,如果B之前有定冠词,则A是主语。不过,关键还要看哪一种意思更合理。
