Before I ask questions, please read the following content first.
The interviewees were trying very hard to impress the interviewers that they were very capable and should be given the job.
This content came from an important English test in some country.
What confused me most is why that-clause seems to give more information but without any verb to connect. To me,it is like:
The interviewees were trying very hard to impress the interviewers and "show" that they were very capable and should be given the job.
Why I think it is odd is that "impress" often just connects one objective in sentences but it'll connect two objections if we don't place any verb in front of that-clause in this sentence.
So, could you tell me what that-clause functions as in this sentence? And,is that-clause an objective in this sentence?why can that-clause be put there? Anyway,I think that it has some grammatical errors, doesn't it?(btw,is this tag question correct?)
