in which & with which

其實兩句都有一個字句被加入主句中，你有冇諗過係乜野？畀五秒自己諗下．．．

１．We have strong links with UK and Australia.
^^^^^^^^^^^^^^^^^^^^
２．The wide community is comfortable with that pace.
^^^^^^^^^^^

見到未？當子句加入主句，而被 which/who 代替o個個詞語變身移左去子句最前時（即 which the wide community is comfortable with），有時會剩低個 preposition o係最後。有ｄ人覺得 preposition 放最後令句子好醜樣，所以將 preposition 放到 which/who 之前。

所以，呢ｄ情況唔知用乜野 preposition 時，先睇番子句係乜。１．用其他地方連繫梗係 with 啦；２．要識 comfortable with something。咁咪搞掂囉～

唔記得左出唔到連續o既space．．．兩句子句我想 underline o既係：１．UK and Australia２．that pace都係被 which 取代

You have to identify the object to which the preposition is
attached.
In sentence ( 2 ), it's "a pace."

i.e. the wide community is comfortable X a pace....

Therefore, the obvious choice is "comfortable with."
i.e. a pace which the wide community is comfortable with
= a pace with which the wide community is comfortable ( formal )

Likewise, in sentence ( 1 ),
look for the object onto which the preposition after "strong
link" clings:
It's "UK and Australia"
i.e. strong links WITH UK and Australia

Putting back everything into the sentence:
...such as UK and Australia which we have strong links with.
= ...such as UK and Australia with which we have strong links. ( formal )

Hope this helps.
