This is generally irreplaceable by others. It is easy to write a work summary, but it requires skill. The trick is to let your leader know about you, so write a few points:

1. What did you do this week? Concise and to the point.

2, which of these things need to be solved with your personal skills, or need your personal brain to solve, so that leaders can see that you are working hard with your brain. Even if there are no problems, we should write down the difficult problems and solve them through our own efforts without bringing a burden to the company.

3. Through this week's work, what new knowledge do you have about your position and work?

4. What abilities need to be improved or what knowledge needs to be supplemented in the future work, and you have already started to do and learn.

5. The boss likes spontaneous people and doesn't like people who push around. Therefore, the work that is not assigned to you is your work, so you should be prepared first.

You have written all these points, and the number of words is almost the same.
