11．Hot the night air was，we slept deeply because we were so tired after the long journey.(2012·陕西，18)

A．although B．as

C．while D．however

答案　B

解析　考查状语从句。hot作从句的表语，提前时从句用倒装，即as引导的让步状语从句要用倒装，而although不用于此结构。故选B。

12．-It was careless of you to have left your new bike outside all night.

-My god! .

A．So did I B．So I did

C．So was I D．So were you

答案　B

解析　B项的意思是"我确实把它放在了外面"，表示同意对方的话。A项表示"我的情况和你的情况一样"；C、D两项的谓语动词是be动词，而主句说明的是行为动词，因此排除。

13．For miles around me there was nothing but a desert，without a single plant or tree .

A．on earth B．for distance

C．in sight D．at place

答案　C

解析　in sight的意思是"在某人的视线以内"；on earth的意思是"究竟"。for distance和at place本身就是错误的。

解析　in honour of为了纪念；instead of代替；in favour of赞成；by means of通过......的方法。由句意知选A。
