(2)sixteenyearolds 是由连字符连接的合成名词,意为“十六岁的孩子”。
(3)allow sb. to do sth. 允许某人做某事。其被动结构为: be allowed to do sth. (被允许做某事)。should be allowed to drive为含有情态动词的被动语态。如:

巧记口诀:分开是“一段”(some time),相连为“某时”(sometime);分开s是“倍;次”(some times),相连s是“有时”(sometimes)。如:

对……认真。about为介词,后接名词、代词或动名词作宾语[来源:学科网ZXXK]
【拓展】 way的常用短语:

☆Of course we want to see him achieve his dreams. 当然,我们想看到他实现他的梦想。
(1)achieve一般只用作及物动词,其宾语可以是实现的目标、目的等,也可以是取得的胜利、成功、名誉、地位等。如:
Everybody should be given the chance to achieve their aims. 要让每个人都有机会实现自己的目标。
(2)因achieve一般与令人愉快的事 (如成功、成就等)连用,所以平时不要受汉语的影响用此词来表示一般意义的“达到”。
(3)achieve的名词形式为:achievement 成就;成绩。如:
He was rewarded by the government for his scientific achievements. 他因在科学上取得的成就受到政府奖励。
☆ We have nothing against running! 我们并不反对赛跑!
(1)against prep. 反对;违背。其反义词为for,意为“支持”。如:
There are 26 votes for him and 8 against him. 有26票赞成他,8票反对他。
(2)against用在fight, strive, struggle等词后面,同with意思相同,不过against更强调一种困难中的反抗。如:
We fight for the weak against the strong. 我们支持弱者反对强者。
(3)against作为介词时,后面接的宾语有时可省略。如:
He had intended to come but somehow decided against (it). 他本来打算来,但不知何故他决定不来了。
☆He needs to spend more time on his homework because it is difficult to become a professional sports star. 他需要在作业上多花点时间,因为成为一名职业运动明星是很难的。
这是一个because引导的原因状语从句,从句部分的it是形式主语,真正的主语是动词不定式to become…。这种句型结构可总结为:it is +adj.(+for sb.) +to do sth.,意为“对某人来说,做某事怎么样”。如:
It is important for teenagers to learn to think for others. 对青少年来说,学会为他人着想很重要。
☆ Only then will I have a chance to achieve my dream. 只有那样我才会有机会实现我的梦想。
only位于句首表强调,后面的句子需要倒装。如:
Only then did he understand it. 直到那时,他才明白。
