The tendency nowadays to wander in wildernesses is delightful

　　to see. Thousands of tired, nerve-shaking, over-civilized people are __1__

　　beginning to find out that going to mountains is going home; that wildness is a necessity; and mountain parks and reservations are __2__

　　useful not only as fountains of timber and irrigating rivers, and as __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-souled exercise, 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 the scenery exists in its most artificial forms, 　mixed with spectacles, silliness, and kodaks; its devotees

　　arrayed gorgeously than scarlet tanagers, frightening the wild game __9__

　　答案及解析:

　　1.nerve-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。

　　3.and--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。

　　4.vicious--vice

　　vicious是形容词，它对应的名词形式是vice。

　　5.that--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。

　　6.back^--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。

　　7.breathes--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。

　　8.was--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.
