A.since B.as C for D with为什么选D
I wasn't first ________, for I saw smoke ________ from the window. A. to arrive; to rise B. arriving; rising C. to arrive; rising D. having arrived; risen
为什么用 to arrive
答
第一题：因为这个falling是非谓语 所以只能用with 其他的是连词 加句子
二：the first to do第几个干什么的。就是不定式
答
1.这是独立主格结构，A,B后要加句子，故不选。for用于独立主格结构的情况我还没见过。有个例句：With the homework having been down ,we could go to the park.可翻译成由于。
2.固定结构，first等叙数词以及something等一些词后，要用to do 结构。
答
第一个问题,with引导整个句子做状语,而其他的是自己这个词作状语,不是整个句子,而英语中要求一个句子只能有一个主语一个宾语一个谓语,如果不是with,那么句子就有两个主语两个谓语了.
第二个问题,固定用法,记住：前面有序数词的情况,后面的动词要用不定式.而第二个空是动名词作状语.
