单选题
The round, hard-shelled nuts of the macadamia tree grow in clusters and are covered with husks what split when the nuts are ripe
【正确答案】
C
【答案解析】答案:C what>> that
分析:考点是what 与 that 的混用;what 不能作为引导词引导定语从句,必须改为 that;在本题中,that split when the nuts are ripe 作为定语从句修饰 husks。
翻译:澳洲坚果树上的圆形、有坚硬外壳的坚果成堆生长,并且被外壳所包裹,这些外壳在坚果成熟时会裂开。
