　　新概念英语第三册Lesson46课文重点精讲解析

　　1 So great is our passion for doing things for ourselves, that we are becoming increasingIy less

　　dependent on specialized labour.

　　全句使用的基本句型是so...that意为"太...以至于..."引导结果状语从句。

　　So great is out passion 为倒装语序，其正常语序是Our passion for doing things for ourselves is so

　　great that...

　　为了强调great这个词，把so great提到句首，因此主谓语要倒装

　　Become/be dependent on 意为"依赖，依靠"

　　e.g. In China, farming is no longer dependent on the weather. 在中国，种田不再完全靠天了。

　　2 No one can plead ignorance of a subject any longer, for there are countless do-it-yourself

　　publications.

　　plead ignorance of sth. 以不知道......为借口

　　e.g. He pleaded ignorance of the accident.

　　Not ... any longer=no longer,表示"不再"，本句中No one构成了否定形式，因此应使用any longer，不应使用

　　no longer

　　do-it-yourself为合成词，意思自己动手做的。

　　合成词是将一个词组或一个句子中的每一个单词用连字符链接，作为一个单词来使用的构词形式。这类合成词多作

　　为定语。E.g.

　　a can't-be-put-down photo 一张爱不释手的照片

　　3 Armed with the right tools and materials, the newlyweds gaily embark on the task of decorating

　　their own homes.

　　armed with引导的过去分词短语，在句中做方式状语，修饰embark。Be armed with意为"装备"，相当于be

　　equipped with

　　embark on 开始从事

　　4 Men, particularly, spend hours of their leisure time installing their own fireplaces, laying out

　　their own gardens; building garages and making furniture.

　　spend (in) doing sth. 句中的installing,laying out,building和making均为spend后使用的动名词形式，作宾

　　语。

　　lay out 布置，设计，花钱

　　e.g. The word for tomorrow is all laid out.明天的工作都安装好了。

　　5 Some really keen enthusiasts go so far as to build their own computers.

　　so...as to与so as to的区别

　　(1)so...as to表示程度及其结果，即"如此......以致"，与so...that...意思相同

　　e.g.He worked so hard as to pass the final exams.他学习非常刻苦，以致通过了期末考试。

　　(2)so as to表示目的，即"为了，为的是"，同in order to

　　e.g.He worded very hard so as to pass the final exam.他学习非常刻苦，为的是通过期末考试。

　　6 Such things provide an excellent outlet for pent up creative energy, ut unfortunately not all of

　　us are born handy men.

　　Pent up 被抑制的

　　Be born 意为"生来就是，命中注定"

　　7 As far as I could see it needed only a minor adjustment: a turn of a screw here, a little

　　tightening up there, a drop of oil and it would be as good as new.

　　句中a turn of, a little tightening, a drop of 作adjustment的同位语，说明adjustment所包含的内容。

　　as good as=almost, actually，意为"几乎，实际上"

　　e.g. The work is as good as perfect.这工作几乎是完美的。

　　8 The mover firmly refused to mow, so I decided to dismantle it.

　　一般情况下，动词refuse的主语是人，但文中用物体mower做主语，是拟人用法，这样可以使文字更显得生动

　　9 After buying a new chain I was faced with the insurmountable task of putting the confusing jigsaw

　　puzzle together again.

　　句中使用insurmountable和confusing两个较大的词分别修饰task和jigsaw puzzle，具有夸张意味，并以暗喻手法

　　，将lawn mover比作jigsaw puzzle(拼图游戏)更有利于产生喜剧效果。

　　10 Buried somewhere in deep grass there is a rusting lawn mower which I have promised one day.

　　Buried somewhere 为过去分词作定语，修饰lawn mower。置于句首位置，一方面起到强调作用，另一方面，由于

　　lawn mower后为which引导的定语从句，这样可使句子显得更为紧凑。
