study可以表成绩吗？
不可以表示成绩，但是可以用做定语修饰成绩。 举个例子： I am really proud of my son's study in this school. 我为儿子在这个学校的学习成绩感到非常骄傲。（此处用study指代学校的教育成果） 再比如： This is the best result you have ever got in a test/examination， hasn't it？ 你在测试/考试中最好的成绩是不是这个啊？（此处用result表示单个的考试或测验的成绩）
又比如说： He had high hopes for his son's future； he was sure that with hard work and good study habits， his son would be able to do well at school and go on to achieve great things one day. 他对儿子的未来充满憧憬；他相信只要努力学习并养成好的学习习惯，儿子将来一定能在学校里名列前茅，并走向成功。（此处用study指代从小的努力程度） 但是你直接用high/good/bad这些形容词来描述分数是不妥当的，应该把分数放在所描述的句子中：
It wasn't so bad／it wasn't terrible. You didn't do too badly. 情况也不算太糟。 You did OK in the exam. 你这次考试考得不错。 I think that's about enough for today——you can mark the paper down as 'not bad'.
我想今天做得差不多了—-你可以把试卷标记为“不错”。 这道题你没来得及做，真是糟透了！ That question you didn't answer made me feel so mad．That was a stupid mistake---you should have said 'I can't explain it'而不是‘the answer is wrong’. It was such a waste of time having that discussion！
那道题你没答出来我真急死了！那个愚蠢的错误你应该说‘我无法解释’，而不是‘答案是错的’。谈这种话题真浪费时间！ This task isn't difficult， but you deserve better than an easy 'A' for it. 这个任务不难，但你不该只得到一个马虎的“A”。
