Question

Among the crises that face humans ________ the lack of natural resources.

A．is

B．a(chǎn)re

C．is there

D．a(chǎn)re there

Answer 1

A

根據(jù)句子結(jié)構(gòu)可知，該句為完全倒裝句。用法為，表示方式或方位的副詞或介詞短語(yǔ)放句首（該句中為(among the crises that face humans) ，句子要使用完全倒裝，即把謂語(yǔ)動(dòng)詞提前到主語(yǔ)之前。由此可知，該句的主語(yǔ)為the lack of natural resources單數(shù)，句子本來(lái)應(yīng)為The lack of natural resources is among the crises that face humans. 因此選擇B項(xiàng)，句意為，缺少自然資源是人類面臨的眾多危機(jī)之一。
【考點(diǎn)定位】考察倒裝句。
