Q 17:

Galileo did not invent the telescope, but on hearing, in 1609, that such an optical instrument had been made, he quickly built his own device from an organ pipe and spectacle lenses.

A.     Galileo did not invent the telescope, but on hearing, in 1609, that such an optical instrument had been made, he

B.     Galileo had not invented the telescope, but when he heard, in 1609, of such an optical instrument having been made,

C.     Galileo, even though he had not invented the telescope, on hearing, in 1609, that such an optical instrument had been made, he

D.     Even though Galileo did not invent the telescope, on hearing, in 1609, that such an optical instrument had been made,

E.      Even though Galileo did not invent the telescope, but when he heard, 1609, of such an optical instrument being made, he

ANS A

请指教 why not B or C?

还有, “on hearing”如何解?

Thanks.

B having 错, had not 时态错.

C 主句没谓语.

on hearing = upon hearing (当听说)

lilyzy

B时态错

C没谓语.

on hearing = 当听说

jnlvo

B用过去完成时had not invented 没依据，没必要。

C中had not invented the telescope和 in 1609搭配错。

“on hearing”

on doing something

解见longman:

▶WHEN SOMETHING HAPPENS◀

formal as soon as someone has done something or as soon as something has happened

B.     Galileo had not invented the telescope, but when he heard, in 1609, of such an optical instrument having been made,

B中最大的问题是but后的句子没有了主语，至于时态还是次要的

C就如2楼所说，缺少一个谓语。

D，on hearing夹心修饰。
E，being made错。

想请教一下，如果but前面连接词没有逗号，是不是就应该是主语一致，后面一个主语就该省略呢？

Galileo did not invent the telescope, but on hearing, in 1609, that such an optical instrument had been made, he quickly built his own device from an organ pipe and spectacle lenses.

重新组织一下结构就是：Galileo did not invent the telescope, but he quickly built his own device from an organ pipe and spectacle lenses on hearing, in 1609, that such an optical instrument had been made.

想请教一下，如果but前面连接词没有逗号，是不是就应该是主语一致，后面一个主语就该省略呢？

1.but, and如果后面的主语和前面的主语一样，那么后面的主语省略，but,and前面不要逗号。

2.but, and后面的主语和前面不一样呢，要有逗号。（除了在从句中！OG里面有这样的例子，就是一个because从句里面，SOV, because A did and B did。这里and前面可以不用逗号）

希望我说的没有错。有问题请大家纠正。俺就要考了，55555555555

第一条好像不是那么的有道理, 即使主语一样也是可以不省略的, 除非是有平行的需要或者是三个句子连到一起.

比如A do B, do C, and do D.

嗯，你说的是对的。我的意思是说如果主语一样，可以省略，当然也可以不省略，比如：A do, and they/it(代替A） do。只要and后面有主语，and前面就要逗号了。是我没有说清楚。-
