高三英语必修5第三单元要点解析：Life in the future(新人教版)

高二英语Unit 3 Life in the future语法知识是关于过去分词作状语和定语的学习。过去分词表示被动或者是动作已经完成。过去分词作定语，表示对于被修饰的词来说，这个动作是被动的，而作状语时候也是表示被动的状态意义。

高二英语Unit 3 Life in the future语法知识点是关于过去分词作状语或者定语。关于过去分词作状语和定语的知识点讲解如下：

过去分词作定语，表示被修饰的名称是动作的受动者，是被动的，也就是说，被修饰的名词是动作的承担者而不是发出者。而过去分词作状语的时候，表示主语进行谓语动作的时候兼有被动的动作，也就是非谓语的动作，而这个非谓语动作是被动的而不是主动的。

详细以及例子解释如下：

过去分词：表示被动或完成。在句子中作的成分是：

⑴作定语

如：boiled water开水： 水已经烧开了，所以用过去分词作定语。

fallen leaves落叶： 树叶已经落下了，所以用过去分词作定语。

newly arrived goods新到的货

the risen sun 升起的太阳

the changed world 改变了的世界：世界是被改变的，所以是被动，用过去分词作定语。

(2) 作状语：Once seen, it can never be forgotten. 一旦被看到，人们就不会忘了。(it是被看到

的) Given more time, I'll be able to do it better.　给我更多时间，我会做得更好。(我是被人家给时间，所以用被动)Filled with hopes and fears, he entered the cave. 心中充满了希望与恐惧，他走进山洞。(希望与恐惧充满了他的内心。对于他来说，这些希望与恐惧是被冲入的，而希望与恐惧是主动占据他的心，所以用被动来作为他进行洞穴的时候的状语词组。

答案：

解析：文章大意：本文就环境、购物、娱乐、交通等方面设想了2025年的人类生活。A 推理判断题。根据第一部分“To get rid of garbage problems, the city will load huge spaceships with waste materials and send them towards the sun，preventing landfill and environmental problems.”可知垃圾运到太空中可防止垃圾填埋现象，由此推知A项正确。

D 词义猜测题。从such as后列举的cinemas，bowling, concerts and others可知该词意为“娱乐活动”。

B 主旨大意题。从第八点所表述的内容可了解到在家也能“旅游”，故可称之为在家度假。
