答案解析:
1.答案: forget being nominated as Charirperson of the Student Union.
详解:
考查forget的宾语为不定式或动名词在意思上的区别: forget的宾语是不定式时,其意思是"忘记" 了将要做的事情;forget的宾语是动名词时,其意思是"忘记”了过去曾经做过的事情,“被提名为学生会主席”是已经做过的事情,故用动名词。
考查被动语态: "我"是"提名"的承受者,故用被动语态。
考查短语: "提名某人为...”表达为nominate sb. as...。
2. 答案: at the expense of their health.
详解:
考查词汇: “以...为代价"可译为at the expense/cost of; 注意,“健康”为不可数名词,译为health.
