题目分析：
本题和第一题有点相似。对于(A)来说，the sandpipers也不能作is a result of residential and industrial development的主语论元，这是因为一种鸟不可能是一个结果，只能说在鸟身上发生的某些事情是一个结果。(B)中as a result of residential and industrial development做is vanishing这个句子的状语，修饰整个句子，表明这个现象是一个结果，这是正确的，答案为(B)。
A中划线部分，主语不是鸟，而是鸟的vanishing，vanishing可以作为一种结果啊？在不认识sandpiper是鸟的前提下，从语法上说，the sandpipers vanishing is a result 没有错啊。vanishing在此用作名词。
如果vanishing是名词，那应该用the sandpipers' vanishing。没有所有格，vanishing是分词，是定语。
