【題目】If sharks’ numbers________too low, it will bring danger to all ocean life.

A.dropB.jumpC.fillD.climb

【答案】A

【解析】

句意:如果鯊魚的數(shù)量下降太低,就會給所有的海洋生物帶來危險(xiǎn)。

考查動(dòng)詞。根據(jù)本句中“sharks’ numbers”和“too low”可知,此處表示數(shù)字下降得太低。drop動(dòng)詞,下降;jump動(dòng)詞,跳躍;fill動(dòng)詞,裝滿;climb動(dòng)詞,爬。故drop符合句意。故選A。
