Hi! See above.@marosa as you instructed, I have tried to make sentences short.
For instance, a person after a hectic day at the office gets back to home, and to get himself relaxed he again has to go to mental and physically exhausting activity, it will only frustrate him further, and might even lead to depression if he does this frequently. (Before Paraphrasing)
For instance, being involved in demanding activities after a hectic day at the office, a person would only add up to his frustration, and might even lead to depression if this becomes routine. (After paraphrasing) Much better!
“For instance, being involved in complex or time consuming activities after a hectic day at the office, a person would only add up to his frustration. Moreover, such activities may lead to depression, in case those become routine”.
Subconsciously, he is learning learns many practical traits by challenging himself such as communicating with strangers, time and finance management, which he may not recognise at that time, but later in his life, it can be of really beneficial for him. (Second long sentence before paraphrasing)
Subconsciously, he learns many practical traits by challenging himself, such as communication with strangers, time and finance management. Although he may not recognise this learning - do you mean apply this knowledge/skills? at that time, later in his life - move this to the end of the sentence, it can be of great use for him. (After paraphrasing. I only added a subordinate clause and converted it into two separate sentences.)
I am learning participle clauses to make writing compact. Since time is short before the test, I might only able to learn basic use of it.
If you’re taking CD test, you can check and paraphrase sentences in the end. Just make sure there’s time left for that.
