1. A
run在此处表示“变成，变得”的意思，尤其指不利的变化，run short为一个固定搭配，指“缺乏，缺少”。flow“流，流动”；become“变化，变得”；move“移动”。结合句意，可知A为————佳选项。
2. A

send off“寄出，发出，邮购”；give up“放弃，投降，认输”，send down“判（某人）入狱，开除”；give off“发出，放出（气味、热、光等）”。
5. B

6. D
反意疑问句前后两部分谓语应是肯定陈述 否定疑问或否定陈述 肯定疑问。当陈述部分有used to do结构时，疑问部分的谓语用usedn’t 或didn’t。
7. D

8.C
具有否定意义的副词或词组用于句首担任状语时，句子要用倒装结构。所以本句中助动词要放在主语的前面，形成部分倒装。又因never before引导的从句一般用完成时态，所以选C。
9.C
过去分词做状语，含有被动含义。本句中主语the city和动词see之间的关系是动宾关系，因此用过去分词。
10. A
