1.C

【句意】约瑟夫的车爆胎了。他现在所能做的就是走到最近的电话亭。

【解析】语法结构——主语从句。结合四个选项和空格所在句缺少一个主语知所填入内容需充当主语，故可直接排除属于完整句子的D项“He can do something”以及缺少先行词的A项“That he can do”；再由“当先行词为all、something、nothing等不定代词时关系代词只能用that”知C项“All that he can do”正确。

2.D

【句意】刚上大学时，他事实上对自己的经济学专业感到茫然不知所措。

【解析】固定搭配。由句中关键词“When he first started in university他刚上大学时”的对应知可构成固定搭配“feel at sea with…对……感到茫然不知所措”的D项正确。
