【題目】We students should do everything we can________ COVID-19(新型冠狀病毒).

A.preventB.to preventC.preventing

【答案】B

【解析】

句意:我們學(xué)生應(yīng)該盡我們所能來預(yù)防新型冠狀病毒。

考查動(dòng)詞不定式。prevent動(dòng)詞原形;to prevent動(dòng)詞不定式;preventing動(dòng)名詞,現(xiàn)在分詞;do something to do sth表示“采取措施做某事”,根據(jù)we can作定語,分析句子可推測出此處是缺動(dòng)詞不定式作目的狀語,故選B。
