专八改错练习第二十一篇：

 The tendency nowadays to wander in wildernesses is delightful
to see. Thousands of tired, nerve-shaking, over-civilized peopleare __1__
beginning to find out that going to mountains is going home;that wildness is a necessity; and mountain parks andreservations are __2__
useful not only as fountains of timber and irrigating rivers, andas __3__
fountains of life. Awakening from the stupefying effects of the
vicious of over-industry and the deadly apathy of luxury, they are __4__
trying as best they can to mix and enrich their own little ongoings
with that of Nature, and to get rid of rust and disease. Briskly __5__
venturing and roaming, some are washing off sins and cares of the
devil's spinning in storms on mountains, bending down and parting
sweet, flowery sprays; tracing rivers back their sources, getting in __6__
touch with the nerves of Mother Earth; jumping from rock to rock, panting in whole-souledexercise, and rejoicing in deep, long-drawn
breathes of pure wildness. This is fine and natural and full of promise. __7__
So also was the growing interest in the care and preservation of __8__
forests and wild places in general, and in the half wild parks and gardens of towns. Even thescenery exists in its most artificial forms, mixed with spectacles, silliness, and kodaks; its devotees
arrayed gorgeously than scarlet tanagers, frightening the wild game __9__
with red umbrellas,--even this is encouraging, and may well be
regarded as a hopeful sign of times. __10__

答案及解析(反白可见):
-shaking--nerve-shaken
句中用的是shake“动摇（信心，信念）”这一意义，而作为这个意思是，shake是及物动词，例如：She was shaken by the crisis。所以作为名词定于应该用它的-ed形式。
2.^mountain --that
谓语动词词组find out 后面实际上有三个并列的宾语从句，当宾语从句并列时，只有第一个宾语从句的引导词that可以省略。而人们常常把最后一个宾语从句的引导词that省略掉。
--but
前文中有一个“not only”，那么后面必须要有“but（also）”与之对应，否则这个结构便是不完整的。
s--vice
vicious是形容词，它对应的名词形式是vice。
--those
代词和它的先行词必须保持单复数的一致，原文中that的先行词应该是on-goings，那么应该用that的复数形式those。
^--to
trace back to 的意思是“追溯到”，其中副词back可以省略，然而介词to是不可以缺少的。
es--breaths
breathe和breath这两个词容易混淆，前者是动词，后者是名词，这里是名词形式，所以用breath的复数形式breaths。
--is
虽然这一句很长，它的结构是动词替代“so+代动词do+somebody”最简短反应。代动词do包括助动词be、have、do等情态助动词。在一般情形下，代动词do的时态与前句是一致的。
9.^gorgeously--more
既然这个句子中有“than”，那么就应该有比较级与之搭配。
10.^times--the
表示时代是，要用复数加定冠词the times。如：
He is not willing to move with the times.
