一道GMAT句子改错题
The direction in which the Earth and the other solid planets - Mercury,Venus,and Mars - spins were determined from collisions with giant celestial bodies in the early history of the Solar System.
a.spins were determined from
b.spins were determined because of
c.spins was determined through
d.spin was determined by
e.spin was determined as a result of
为什么是 spin 而不是spins 主谓宾划分完后怎么分析!
答
整句的主语是direction,in which 是定语从句啦,然后那个 - Mercury,Venus,and Mars -是插入,用来修饰plants.整句的谓语动词应该是原句的were,而主语是单数,所以were要改为was.be determined by 是固定搭配,所以我觉得应该是选d
