專八改錯練習第二十一篇：

?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(反白可見):
-shaking--nerve-shaken
句中用的是shake“動搖（信心，信念）”這一意義，而作為這個意思是，shake是及物動詞，例如：She was shaken by the crisis。所以作為名詞定于應該用它的-ed形式。
2.^mountain --that
謂語動詞詞組find out 后面實際上有三個并列的賓語從句，當賓語從句并列時，只有第一個賓語從句的引導詞that可以省略。而人們常常把最后一個賓語從句的引導詞that省略掉。
--but
前文中有一個“not only”，那么后面必須要有“but（also）”與之對應，否則這個結構便是不完整的。
s--vice
vicious是形容詞，它對應的名詞形式是vice。
--those
代詞和它的先行詞必須保持單復數(shù)的一致，原文中that的先行詞應該是on-goings，那么應該用that的復數(shù)形式those。
^--to
trace back to 的意思是“追溯到”，其中副詞back可以省略，然而介詞to是不可以缺少的。
es--breaths
breathe和breath這兩個詞容易混淆，前者是動詞，后者是名詞，這里是名詞形式，所以用breath的復數(shù)形式breaths。
--is
雖然這一句很長，它的結構是動詞替代“so+代動詞do+somebody”最簡短反應。代動詞do包括助動詞be、have、do等情態(tài)助動詞。在一般情形下，代動詞do的時態(tài)與前句是一致的。
9.^gorgeously--more
既然這個句子中有“than”，那么就應該有比較級與之搭配。
10.^times--the
表示時代是，要用復數(shù)加定冠詞the times。如：
He is not willing to move with the times.?
