Question

SAT语法题

Though best known as a jazz vocalist, he also enjoyed gospel music, whereby he told his manager that he wanted to make a recording of his favorite gospel songs.

答案说"...whereby...."是错的，那么如何更正呢？
另外whereby这个副词怎么用，举下例子

Answer 1

whereby相当于by which、by what，即“凭什么”。主干部分是逗号前边的部分，逗号的后边进一步补充说明。而本句的主干部分是逗号后边的部分，逗号前边的部分是逗号的后边原因。以此本句更正为：Though best known as a jazz vocalist, he also enjoyed gospel music, so he told his manager that he wanted to make a recording of his favorite gospel songs.或Becaus though best known as a jazz vocalist, he also enjoyed gospel music, he told his manager that he wanted to make a recording of his favorite gospel songs.再举个例子：Straitford's briefs don't sound like the usual Washington back-and-forthing, whereby agencies avoid dramatic declarations on the chance they might be wrong.
此处的whereby相当于by which、by what，即“凭什么”。所以本句的主干部分是逗号前边的部分，逗号的后边进一步补充说明。on the chance的意思是也许能够（做到某事）、希望能够（做到某事），后边经常接that引导的从句。
本句应该重点体会whereby以及on the chance的用法。back-and-forthing在此处应译为“往来公文”。

Answer 2

WHEREBY应该改成SO。
这里是因果关系，
WHEREBY是凭借，约莫等于BY WHICH。

Answer 3

Though best known as a jazz vocalist, he also enjoyed gospel music,
意思是：虽然是个爵士迷，但是也喜欢gospel音乐。

he told his manager that he wanted to make a recording of his favorite gospel songs.

意思是：他告诉他经理他要做一个他最喜欢的gospel歌曲的录音。

上半句说喜欢gospel 音乐，后半句说要录gospel的歌，要用连词，而whereby是副词所以不行。接一个连词，如so之类的就可以了。
whereby 改成so。

whereby的用法：
Whereby shall we know her?
我们靠什么认出她呢？
