关于非谓语的练习题,希望能给出分析过程 1.there are five pairs ___,but i'm at a lost which to buy.a.

选B
A.to be chosen from
B.to choose from
C.to choose
D.for choosing
在there be结构中,不定式作定语可用主动形式表达被动含义.
另外from不能省略,表示从5双鞋子中挑选
----
解析：本题用不定式作定语,表示“在众多的东西中挑选.”在there be结构中,不定式作定语可用主动形式表达被动含义.故排除A.再如：Do you have any ink to write in 该题中用不定式to choose from作five pairs的定语,表示“从……中挑选”.当不定式作定语时,若不定式是“动词+介词”结构,其介词不能省略.因此答案为B项.
句意为“有五双可供选择,但是我拿不定主意买哪一双.”
