study作为大学某门“学科”解释的时候，有两种用法：一是做不可数名词用；二是做可数名词用。这两种用法都对。但是做可数名词的话，它总是以复数形式出现。

一家之言，仅供参考

勤查英英，必有所获！

备注：study作为学科类名词的复数形式studies通常指“多门学科研究”作定语也用复数形式。

例如下面2所大学英文名称就可以很少说明这种复数名词studies作定语的语言现象。

【1】北京外国语大学Beijing Foreign Studies University

【2】上海外国语大学Shanghai International Studies University

Social studies=social science社会科学课程(包括社会学/经济学/政治学等课程)

social studies teacher=从事社会科学研究的老师

【1】social studies英文解释(1) In Britain, social studies is a subject that is taught in schools and colleges, and includes sociology, politics, and economics.

【2】social studies英文解释(2)In the United States, social studies is a subject that is taught in schools, and that includes history, geography, sociology, and politics.

When I was in middle school, my social studies teacher asked me to enter a writing contest. I said no without thinking. I did not love writing. My family came from Brazil, so English was only my second language. Writing was so difficult and painful for me that my teacher had allowed me to present my paper on the sinking of the Titanic by acting out a play, where I played all the parts. No one laughed harder than he did.

当我在上中学的时候，教我的社会学科的老师要我参加一个写作比赛。我不假思索就拒绝了。我不喜欢写作。我的家庭来自巴西，所以英语只是我的第二语言。写作对我来说是如此困难和痛苦，以致于我的老师允许我通过表演一个剧本来展示我关于泰坦尼克号沉没的论文，我在该剧中扮演了所有的角色。没有人比他笑得更厉害的了。
