Why is this unnatural? Please help me!
Please read this: "Inside Out is about a girl named Riley and her personified emotions. Riley is an ordinary cheerful girl who likes to play hockey. She has a very happy childhood with her parents and hockey team. But she suddenly moves to a shabby house and transfers to a school. To adjust her to the new environment, her emotions work harder than usual. ~~~~"
The two following sentences are the corrections for the last sentence in that paragraph.
"Her emotions work harder than usual, in order to help her adjust to the new environment."
"Her emotions work harder than usual, in order to adjust her to the new environment."
They are the same in two points.
1)Why does "in order to" sound more natural than "to infinitive"?
2)Why is it awkward to put the adverbal phrase before ", her emotions work.."? I thought that putting the adverbal phrase at the beginning of the last sentence would be natural because I focused on Riley before the last sentence.
I need your help. Thank you in advance!
