写作不是背出来的，是练出来的。贴一段你写的英文，教练逐句批改：哪里是中式直译、哪里啰嗦、哪里语法露怯，每处给改法和原理。每天免费练一次；$2/月 不限次数，练多少交多少篇。
Writing improves by reps, not rules. Paste your English and get sentence-by-sentence coaching: what reads translated, what's bloated, what betrays grammar gaps — each with the fix and the why. One free drill a day; $2/month for unlimited reps.
$2/月，想练几篇练几篇：逐句批改 + 重写对照 + 针对你错误模式的专项小练习。随时取消。$2/month, as many passages as you want: sentence-level coaching + a rewritten version + micro-drills targeting your own error patterns. Cancel anytime.
