A: You know that? Joan has got the scholarship.
A: But I think Henry is a backroom boy. He always helps her with her study.
B: You'er right.
Backroom boy的意思是“幕后英雄”“默默无闻的人”，其英文释义为： scientists, researchers, etc. who do important work but do not have direct contact with the public。
E.g. Although he is a skilled political strategist, he lacks the charm and charisma necessary to run for office himself and, therefore, is likely to stay a backroom boy for the rest of his career.
E.g. It's thanks to the back-room boys more than to the sales team that the product is such a success.
help someone with something：帮助某人做某事
E.g. He's always pestering me to help him with his homework.
E.g. All the neighbors clubbed together to help him with his debts.
get the scholarship：获得奖学金
E.g. He is bound to get the scholarship. No other applicant is better qualified.
