1．The supermarket discounted coffee at 30%, so there was such a long queue for it that we ________ gave up.
A．generously B．purposefully
C．eventually D．unfortunately
C 解析：句意：这家超市的咖啡在打七折销售，所以购买的队伍很长，以至于我们最后还是放弃了。eventually “最后，终于”，符合句意。generously “慷慨地”； purposefully “有目的地”； unfortunately “不幸地”。
2．Mrs.Smith, ________ her husband and daughter, ________ going to the Great Wall.
A．as well as; is B．as well; are
C．as well as; are D．as well; is
A 解析：as well as连接两个并列成分作主语时，句子的谓语动词的数要与as well as前面的名词或代词保持一致。
3．________ others in the reading room, Jack walked in on tiptoes.
A．Not disturbing B．To not disturb
C．Not to disturb D．Not having disturbed
C 解析：句意：为了不打扰阅览室里的其他人，杰克踮着脚尖走了进去。此处为目的状语，现在分词作目的状语时往往放于句末，故可排除A 和D; 不定式作目的状语时其否定式应在 to 前加 not, 因此选择C。
