Unit 7 The Adventures of Tom Sawyer第 2 课时 课文重难点句型讲解栏目导航巩 固 习 题1．He knew the boys who were free would soon come along and make fun of him. 他知道那些有空闲的男孩很快就会过来取笑他。 （1）这是一个由关系代词 who 引导的定语从句，the boys 是先行词，关系代词who 在句中作主语。例如： He is the boy who wants to see you. 他就是那个想要见你的男孩。 （2）be free 意为“空闲的；有时间的”。例如： I will go to visit my grandma if I am free this weekend. 如果这个周末我有空，我会去看望我的外婆。 2Aunt Polly warned me to do it well.． 波莉阿姨告诫我要做好这件事。 warn sb. to do sth. “意为 告诫某人做某事”，warn sb. not to do 其否定表达为：sth.warn sb. against doing sth. “，相当于意为 告诫某人不要做某事”。例如： Our teacher always warns us not to break the school rules. =Our teacher always warns us against breaking the school rules. 我们的老师总告诫我们不要违反学校的规章制度。 warnwarn sb. against sth.此外，还用于句型。例如： When I was a child, my mother warned me against fire. 小时候，我的妈妈告诫我不要玩火。 3．I’m the only person that can do it right. 我是唯一一个能够做好这件事的人。 这是一个由关系代词 that 引导的定语从句。先行词 person 的前面用了 the only 来修饰，所以这个定语从句只能用 that 来引导，而不能用 who。例如： Kate is the only one that fails the English exam. 凯特是唯一一个英语考试不及格的人。 巩 固 习 题一、根据课文内容，用所给单词的适当形式填空（未提供单词的，限填一词），使文章意思完整、正确。 Miss Liu wanted to encourage her students to read famous books.
