Questions & Answers about zhè zhèngmíng jìshùrényuán lái le.

What is the basic structure of 这证明技术人员来了?

The pattern is:

这 + 证明 + 技术人员来了

That is:

• 这 = the subject, meaning this / this fact / this evidence
• 证明 = the main verb, prove
• 技术人员来了 = a whole clause acting as the object of 证明

So Chinese is doing something very natural here: after a verb like 证明, it can put an entire mini-sentence.

Why is there no word for that after 证明?

Because Chinese often omits that in this kind of sentence.

In English, we say:

• This proves that the technician has come.

In Chinese, after verbs like 说 (say), 觉得 (feel), 知道 (know), 证明 (prove), the next clause usually just comes directly after the verb:

• 这证明技术人员来了

So the idea of that is understood and does not need to be said.
