vv，你好，我顺着你给的链接来到了这个帖子，能否问一下helr的解答在哪找，以及夸克的语法大全是什么吗？ ...

hi clacry

helr解答：https://gmat.la/question 有些题目有，有些没有

夸克的语法大全我也不知道是啥，那是prep08笔记里写的

LZ我又来了，我看到了RON对于having done的解释，非常豁然开朗，跟你分享～

i can actually say, with a fair amount of confidence, that you can safely just eliminate choices that have "NOUN + having been __ed" (WITHOUT a comma).
people who have graduated from school X ...       MAKE SENSE
people having graduated from school X ...          NONSENSE
(because "having graduated" can't be temporary -- once someone HAS GRADUATED from somewhere, that's true forever)
for the same reason, "NOUN having VERBed" really won't make sense anywhere.因为一旦have done sth,就是 permanent ，不可能变成have not done

以及这个帖子里的总结太好了：V-ing和which用法总结
LZ有时间可以看看哦

我觉得好眼熟，于是刚刚翻了一下我看Ron视频时做的笔记：

在2015-3-26 “the use of and"的视频中，Ron提到了这个题

The yield of natural gas from Norway's Troll gas field is expected to increase annually until the year 2005 and then to stabilize at six billion cubic feet a day, which will allow such an extraction rate at least for 50 years' production.

A 2005 and then to stabilize at six billion cubic feet a day, which will allow such an extraction rate at least for
B 2005 and then to stabilize at six billion cubic feet a day, an extraction rate that will allow at least
C 2005 and then stabilizing at six billion cubic feet a day, with such an extraction rate at the least allowing
D 2005, then stabilizing at six billion cubic feet a day, allowing such an extraction rate for at least
E 2005, then stabilizing at six billion cubic feet a day, which will allow such an extraction rate for at least

在谈到C（and then stabilizing）和DE（，then stabilizing）为什么是错的的时候，Ron说因为”then stabilizing“本身就是错的，因为"then" means after, and "v-ing" means simultaneously.此外，类似的例子还有", previously v-ing…" ", now v-ing…"。

看了这个having done的解释，应该是一个道理。

LZ说的对，但是严格意义上来说是另一个点。

LZ提到的是：Ving不能与表示时间的词连用

Ving表示的是伴随状态，time frame 同主句谓语
e.g from Ron
Colin was struck by a bus, dying instantly.                  MAKE SENSE
Colin was struck by a bus, dying in the hospital an hour later. NONSENSE
I am talking to my friend about the girl swimming in the pool yesterday.  NONSENSE
I am talking to my friend about the girl who swam in the pool yesterday. MAKE SENSE
因此当V-ing与表时间的now,yesterday,tomorrow,previously…连用，则暗示动作发生时间相对谓语的变化，必然为错


而having done的问题在于：现在完成时中蕴含的“已经完成”的含义

以下来自Ron
"...that/who[verb]s" implies that [verb]s is a permanent or fundamental aspect of the noun that's described.
"...[verb]ing", on the other hand, implies that it's temporary and can/will change.
e.g
if i tell you that i have friends who work in finance, i'm implying that finance is their long-term career.
On the other hand, if i tell you that i have friends working in finance, then there is no such implication.  (maybe they'll quit tomorrow and become consultants, or form a startup, or retire and move to a tropical island).


因此，having done完完全全不make sense——因为这件事已经完成了，它不可能再变成‘没完成’的状态

当然，如果是 I am talking to my friends about my homework having been done yesterday.
这就是错上加错了。

感谢总结！
comma v-ing/ （no comma） v-ing的意思从此就很清楚啦。

我觉得这个then stabilising 还有一个解释，就是then表示one step and then another step，所以是平行关系，而不是从属关系，因为v-ing的话一定1/两者发生在同一个time frame；2/ing的动作必须是a. direct consequnce of the main verb OR provide additional info of the main verb.
