问题补充：
, but the idea of having to work more than ten hours a day without weekends discouraged me.
A. Wanting to be a teacher
B. Although I wanted to be a teacher
C. I had wanted to be a teacher
D. To want to be a teacher
答案：
A. Wanting to be a teacher
B. Although I wanted to be a teacher
(答案→)C. I had wanted to be a teacher
D. To want to be a teacher
解析：考查want的用法。Had wanted to do sth.=want to have done sth.“本想做某事”。句意“我本来想做老师的，但一想到每天工作10小时，没有周末，我就放弃了。”A项是动名词短语，可以作主语，这里是一个分句，A不完整；although不与but连用，排除B；D项表示目的，与后一分句矛盾，排除D。故选C。
