sixteen-year-olds，sixteen-year-old与sixteenyearsold.

sixteen-year-olds“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。例：Sixteen-year-olds

shouldbeallowedtogooutatnight.应该允许16岁的青少年夜间外出。①辨析②sixteen-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：Mypenpalisasixteen-year-old

boy.我的笔友是一个16岁的男孩。③sixteenyearsold“16岁”，用来描述人的年龄，常在句中作表语。例：Mybrotherissixteenyearsold.我哥哥十六岁了。（2）allow(toletsb.dosth.)及物动词，意为“允许；准许”，常用于下列结构中：①allowsb.todosth.允许某人做某事例：Theteacherallowedhimtogointotheclassroom.老师允许他进教室。②allowdoingsth.允许做某事例：Wedon’tallowsmokinginpublicplaces.我们不允许在公共场所吸烟。③be(not)allowedtodosth.(不)被允许做某事例：Passengersarenotallowedtosmoke.不允许乘客吸烟。3.I’mworriedaboutyoursafety.我担心你的安全。（1）worried作形容词，意为“担心的；烦恼的；焦虑的”。常用短语beworriedabout意为“为……担心”。例：Don’tbeso

worried.Everythingwillbefine.不要如此担心，一切都会好起来的。

拓展

worry可用作不及物动词，其后接宾语时要加about,即worryabout,意为“担心”，可与beworriedabout互换。例：Don’tworryaboutme.别为我担心。4.Sixteen-year-oldsshouldbeallowedtogettheirearspierced.应该允许16岁的青少年打耳洞。

getone’searspierced意为“打耳洞”，此处get为使役动词，相当于make和have，意为“使；让”。“get/have+宾语+过去分词”意为“使某事被做”或“让某人做某事”。例：You’dbettergoandgetyourhaircut.it’stoolong.你最好去把头发理了。它太长了。get用于使役动词还可用于getsb.todosth.结构，意为“使某人做某事”例：Ican’tgethimtochangehisidea.我不能使他改变想法。5.Teenagersshouldbeallowedtochoosetheirownclothes.应该允许青少年选择他们自己的衣服。（1）choose及物动词，其后可接名词或代词作宾语。例：Hechose

choose还可用于以下两种结构：6.Iagree.Theyaren’tseriousenough.我同意。他们不够稳重。

enough副词，意为“足够地”，修饰形容词或副词要后置。例：Youdon’tworkhardenough.你工作不够努力。拓展enough还可用作形容词，意为“足够的；充足的”。修饰名词时，一般放在名词前面，有时也放在名词后面。例：Therewillbeenoughmoneyforus.我们将有足够的钱。Therewillbetimeenoughtorelaxforus.我们将有足够的时间休息。7.Heshouldstopwearingthatsillyearring.他应该停止戴那个可笑的耳环。（1）stopdoingsth.意为“停止做某事”。例：Let’sstoptalking！让我们停止说话吧！辨析stopdoingsth.与stoptodosth.stopdoingsth.stoptodosth.
