The first sentence should belong to the problem of improper use of words. It is ok to use "sensational" upstairs. It can eliminate the language sickness of this sentence.

The second sentence is "save two lives, sacrifice three", which is ambiguous and easy to understand. "Save two lives" can be understood as the person who saved three lives, or as the other three were not saved and sacrificed. You can change the quotation marks to "save two people from drowning and sacrifice three rescuers", so there will be no ambiguity.

The third sentence "carry forward" has no object, but the word "spirit" is added after "carry forward".
