Question

SAT真题求解答

To encourage young people to read, a number of AUTHORS, WHO SELL their books with companion video games that require players to use information from the books to advance in the games.(大写部分为下划线）
A authors, who
B authors, they sell
C authors, having sold
D authors selling
E authors are selling

为什么不选B？

Answer 1

选E

原句A缺了谓语, CD也是却谓语。 B错是因为a number of authors 变多余了，用B的话我给你分析一下

To
encourage young people to read（不定式是目的壮语）, a number of authors, they（主语）
sell （谓语）their books（宾语） with companion video games that require
players to use information from the books to advance in the games. 那么a number of authors 是什么都不是，多余了.....所以直接用E就行
