【分析】
这道题考查英语中代词的不同形式及词性转换,需结合句子成分、语境和固定搭配判断单词的适当形式。第1题围绕you的不同形式:动词后接宾格、名词性物主代词表所属、形容词性物主代词修饰名词;第2题用change的不同形式:冠词后接名词、第三人称单数主语对应动词单三、固定搭配make sb do sth用动词原形;第3题用build的不同形式:形容词后接名词、复数主语对应动词原形、固定名词搭配。
【解析】
1. 第一空:动词meet后接人称代词宾格,填you;第二空:表示“你的(狗)”,用名词性物主代词yours;第三空:修饰名词care,用形容词性物主代词Your;第四空:情态动词Can后接人称代词宾格,填you。
2. 第一空:冠词a后接名词,填change;第二空:主语it是第三人称单数,一般现在时谓语动词用单三形式changes;第三空:固定搭配make sb do sth,用动词原形change。
3. 第一空:形容词tall后接名词,填building;第二空:主语Many workers是复数,一般现在时谓语动词用原形build;第三空:固定搭配classroom building(教学楼),填building。
