Translation:The author is talking about what he experienced during the war.
Oh come on Duo, along with Antoinette and nguyen, I would also like to know why you mark incorrect:
"The author talks[speaks] about[of] what he experienced during the war"
In earlier modules you taught us:
Il parle = he is talking : he talks : he is speaking : he speaks
Please explain what is incorrect with our translations.
If the author is in the process of delivering a talk about his life, or is being interviewed, then this is fine. If this is a commentary by someone else about a book by the author, then it would be more normal in English to say "The author is writing about.....". However we would then use the past tense. Once again, without the context it is difficult to know what is going on here.
