We use the construction 固然…但是… to gently express a disagreement or opposite point of view: “That's true, but…”.
We should state 固然 in the first part of the sentence right after the subject. In the second part, we firstly state the conjunction “but” 但是 , 可是 , 不过 and then say the fact that diminishes the importance of what was said in the first sentence.
Pay attention
Sometimes 但是 and 可是 may be shortened to 但 and 可 respectively.
Scheme
subject 1
固然
predicate 1
“but”
(subject 2)
predicate 2
Pay attention
If the sentence has two subjects, we state the first one before 固然 and the second after the conjunction “but” and before the second predicate.
