be poor in
be good at
Ⅰ . be good at / in 意思接近于 do well in. “在(某方面)出色;擅长……”. be good at / in 强调一种笼统情况,而do well in 可表示一种情况,也可指在具体的一次活动中表现出色. be good at 的反察颂义词组为:be poor (weak) at (in). do well in 的反义词组为:do badly in. 如:
① Mary is good at / in maths. = Mary does well in maths. 玛丽数学很好(指情况).= 玛丽数学学得很好.
② Tom did well in (不宜用be good at.指具体一次)that English test / sports meeting.汤姆在那次英语考试中(运动会中)考得很好(表现出色).
③ Wu Dong does badly in his lessons. = Wu Dong is weak / poor / at / in his lessons.吴冬功课不好.(指情况)
④ Mei Ying did badly in the high jump 梅英在跳高比赛中成绩不好.(具体一次,不宜替换.)
⑤ Mei Ying is weak / poor in / at high jump.梅英派返不善于跳高.(指笼统尘没饥情况)
Ⅱ . do well 和 do badly 可单独使用,表一种情况;而 be good / weak / poor 一定要借助于介词 in 或 at, 强调在某一个方面,才能表达一个完整的意思.如: He does well / badly at school. 他在学校里功课很好/很差. I hope I can help you!
