题目解答
答案
C,mouthpiece只有C) that is inserted 可以正确表达嘴管插入管子这个动作采用了被动语法
解析
步骤 1:分析句子结构
句子的主语是 "All brass instruments",谓语是 "use",宾语是 "a mouthpiece"。句子的后半部分需要一个从句来修饰 "a mouthpiece",因此需要一个关系代词 "that"。
步骤 2:确定关系代词
关系代词 "that" 用来引导定语从句,修饰先行词 "a mouthpiece"。
步骤 3:确定从句的时态和语态
从句的主语是 "a mouthpiece",谓语是 "insert",由于 "a mouthpiece" 是被插入的,所以需要使用被动语态。因此,从句的谓语应该是 "is inserted"。
步骤 4:选择正确答案
根据以上分析,正确答案是 C) that is inserted。
