885 SEC C-18(THEN)

gemj

还有一种可能是THEN还是作副词，但就是不用AND来连接两个句子。
我见过两个形容词并列但不用AND的情况。
这也算是一种流氓行为吧？
不管是哪种可能，都挺流氓的。

我个人认为，应该从意思上去理解该题。

Owner省取暖费是通过2个步骤进行的。1）putting all his refrigerator air compressors together in an insulated compartment。2）then installing two fans and a duct that carried waste heat from the compressors into the main part of the store.

A中，装fan和duct是一起进行的。duct引热量。
D中，carry的宾语为waste heat ，主语为owner,变成了owner通过duct引热量，而非duct引热量。意思有错误。

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.
(A) setting free the more than 500 slaves who were legally considered
(B) setting free more than the 500 slaves legally considered as
(C) and set free more than 500 slaves, who were legally considered as
(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

Office Guide #154題 ,請參考
by filing .... setting 並列 .

而#18這題，因為then是adv. ,所以可有可無,不影響文法結構.

og这道题， by filing .... setting 不是并列，setting----是做结果状语修饰filing这个动作的。og中是这么说的“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.... ”

hey, guys, i think A is wrong. who carries waste heat? not the owner, nor the fans, but DUCT. fans and the duct r different apparatus, they can't be together. So choice D is right. by installing ... , installing ... and a duct carrying ... very clear

Snazzy

sorry, i mean, i chose E not D

may1129

B is wrong,  ‘he installing’
C is wrong, first half active, second half passive, violate parallelism
D is wrong,  ‘ and then carrying …waste heat’ – hey, how can the owner carries out waste heat (which is a form of gas)’  (note, in English, who is carrying out the action, who is the subject of the action should be crystal clear)
E is wrong,  but I think it’ll be right if the comma is not used, which function as the means by which the owner used to achieve savings,  as  ‘owner saved $$ by doing …, installing two fans and a duct carrying out heat”,  

A is correct, then doesn’t function anything, can be omitted.

Snazzy

it sounds rational that E is not ferfect. however, i am still not convinced to choose A

then一辭的用法,
在Colins Cobuid English Grammar書中 8.137
將 and, or, but, yet, nor, then
定義為並列連詞 coordinating conjunction
可以連接子句,動辭,名詞組,形容詞,副詞或其他辭組

且有時可以兩個並列連接詞並用
Ex: Eric moaned something and then lay still.

我想在英文中,
then 有時是可以像 and 這樣來使用的
因此, 我覺得本題B選項沒有動辭, C選項語意不合邏輯, DE選項不合嚴格的平行結構
這題要從文意來解, 困難！
或由主動優於被動捨去C選項也許好作些！


此外,再補充then在該書中談到的其他用法
8.140 講到, and, or, then 連接相同主詞時, 第二個主辭可以省略
Ex: When she recognized Morris she went pale, then blushed.
8.143 then 可以表序列, 但不如and常見
Ex: He held his hand to direct the water in a spray across his face, then dipped his head and drank.
8.26 then 用在 if 條件句中. (6樓gemj大俠提過)
5.74 then當副詞可指前面提過的時間. Ex: We were all so patriotic then.


順便參考:另一本字典上談到then的用法
then
副詞
1.then當<副詞>,表示時間,指(然後);表示結果,指(那麼)。
    I opened the door, then walked out of the room.
    我打開門,然後走出房間。
    If you are tired, then you'd better stay at home.
    如果你累了,那麼你最好待在家裡。
2.then(那時),當<抽象名詞>。
    He stopped smoking from then on.
    他從那時起戒煙了。
    I haven't seen him since then.
    從那時起我一直沒有見到他。

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。
