Many trees in this area have been_to make room for buildings which has worsened our living environment.
A. cut off
B. cut down
C. cuts down
D. cut up
题目解答
答案
B. cut down
解析
本题考查动词短语辨析及被动语态的用法。解题关键在于:
- 区分动词短语含义:需明确
cut off、cut down、cut up在不同语境中的具体含义。 - 被动语态结构:句子中
have been后需接动词的过去分词形式,需注意选项的时态和语态是否匹配。
选项分析
- A. cut off:意为“切断、停止供应”,如
cut off water(断水)。 - B. cut down:意为“砍倒(树木)/砍伐”,符合题干中“为建筑让出空间而砍树”的语境。
- C. cuts down:第三人称单数形式,与句中
have been(复数形式)不匹配。 - D. cut up:意为“切碎”,如
cut up vegetables(切菜),与题意无关。
关键判断
题干中have been为现在完成时的被动语态,需用过去分词作补语。cut down既符合语境(砍伐树木),又满足语法结构要求。
