第二部分：课中重点
sixteen-year-olds 名词，意为“16岁的青少年”，是名词，在“基数词-名词（单数）-形容词”结构中，形容词后加-s表示一类人或事物，相当于sixteen-year-old boys and girls。
注意区分：
sixteen years old“16岁”，用来描述人的 年龄，常在句中作表语。例：My brother is sixteen years old.我哥哥十六岁了。
sixteen-year-old“16岁的”，是由“基数词-名词（单数）-形容词”构成的复合形容词，在句中通常做前置定语，修饰名词。
例：My pen pal is a sixteen-year-old boy.我的笔友是一个16岁的男孩。
“一个16岁孩子”的表达方式：
a child of sixteen
a child of sixteen years old
a sixteen-year-old child
no way 不可能；不行；没门儿
no way是英语口语中一个直接拒绝对方的表达用语，强调不赞同别人的观点，或根本没有可能按其要求去做某事。
— Can I hand in my homework tomorrow — No way.
I don’t think sixteen-year-olds should be allowed to drive.
我认为16岁的孩子们不应该被准许驾车。
英语中有少数表示“猜想、臆断”的实义动词, 如think, believe, suppose, imagine等后面跟含否定意义的宾语从句时, 习惯上把从句的否定转移到主句, 构成“I don't think…” 结构。这种语言现象称为否定转移。
1) 我相信他不会来。 I don't believe he will come.
2)我认为他是不对的。I don’t think he is right.
含情态动词的被动语态
Teachers should not allow students to get ears pierced.(变被动）
Students should not be allowed to get ears pierced.
should be allowed 是含有情态动词should的被动语态。其中，should 为情态动词，表示劝告、建议，意为“应该；应当”，其否定形式为should not/shouldn’t; allowed为allow的过去分词。含情态动词的被动语态结构：情态动词（should, must, may , can, could等）+be+及物动词的过去分词。
