885 SEC C-18(THEN) - ChaseDream - Powered by Discuz!

used to say what happens next or what you do next
Mix the flour and butter, then add the eggs.

以下是引用jnlvo在2004-3-10 11:32:00的发言：
我认为可以这么理解：then还是作副词修饰动词，如有两个动词并列出现通常需用and连接，如：Eric moaned something and then lay still
但当两个动词中间有过多的修饰成分，距离太远，这时and可以省略用，号代替如When she recognized Morris she went pale, then blushed.
本题也可以这么理解，这样then看上去就像连词一样连接两个动词，但它绝不能这样连接两个名词。

这里我想请教NN一下，逗号和and之间的关系：在托福里，逗号就意味着and，例如a big,fat rat=a big and fat rat

by是介词后面要接动名词或名词，所以是putting ，后面的installing是对前面的内容作进一步的解释，不是与

这里也不需要连词,同OG154题一模一样! THEN仅仅是动作转换的过程而已

154. In 1791 Robert Carter III, one of the wealthiest plantation owners in Virginia, stunned his family, friends, and neighbors by filing a deed of emancipation, setting free the more than 500 slaves who were legally considered his property.

(D) and set free more than the 500 slaves who were
legally considered

(E) and he set free the more than 500 slaves who
were legally considered as

This sentence requires that the participial phrase setting free... connect to the gerund construction by filing a deed...; it was the filing of a deed that made possible the setting free .... Choices A and B establish this connection, but only A, the best choice, completes the participial phrase appropriately. In choices B and D the misconstructed phrases set[ting] free more than the 500 slaves ... mistakenly suggest that Carter set free slaves that were not his own. Choices C and D distort meaning by paralleling stunned and set free, as though these were two separate and independent actions. E begins a second independent clause, which--though grammatically acceptable--again distorts the meaning. In choices B, C, and E, considered as is unidiomatic.

我觉得那个then是表示时间先后，那个人先把压缩机放在房子里，然后装了电扇和管子......
只是那个then后面是不是省略了by？表示方式的

请大家指教～
