+ de + complement of degree

Specify the degree or extent to which the object has been affected as a result of the action.


8.1 Lǎoshī wnt jiěshi de hěn qīngchu. 


The teacher has explained the question very clearly.


8.2 Gōngzu h jiāw li de bngdǎo le. 


Work and household chores have exhausted her so much that she has fallen ill.

Note: It is important to remember that the complement comments on the object, not the subject. See the following examples.


8A. Wǒmen dinyǐng knde hěn gāoxng. (Ungrammatical)


(We enjoyed the film very much.)

Note that hěn gāoxng很高兴 in 8A comments on how the subject feels, not on to what extent the object has been affected. Therefore, this sentence should not use the construction. The correct sentence should be:


8A. Wǒmen kn dinyǐng knde hěn gāoxng. (Grammatical) 


We enjoyed the film very much.
