Exercise

Clearly,protecting will come only through coordinated international efforts to control human population, stabilize the composition of the atmosphere, and preserve intact Earth's complex web of life.

When first given to individuals,animals, and places they were chosen carefully with a hope of endowing whatever was named with some sort of magic.

If you think as much of others as of yourself, you will not make any of these mistakes.

要點：to control....,stabilize...,and preserve...為三個并列的動詞不定式,修飾efforts."stabilize"和'preserve"兩詞前省略"to"
譯文：很清楚,保護只有通過國際間的合作努力才能實現(xiàn),通過這些努力來控制人口,穩(wěn)定大氣結(jié)構(gòu),使地球上復雜的生物網(wǎng)完好無損.

要點：when引導的時間狀語從句中,主語是"they",即句子中的"names",謂語動詞是"were given",為了避免重復,與主句中相同的部分省略了.whatever引導的從句作動名詞endowing的賓語.
譯文:當首次給人,動物和地方取名時,總要非常謹慎地進行選擇,希望不管取的名字叫什么,都能為其賦予某種魔力.

要點：句中as much ....as連接的平行結(jié)構(gòu)有兩個: think of others和(think) of yourself.在連詞as后面省略了與前半句相同的部分think.全句應為: If you think of others as much as you think of yourself....
譯文：如果你像關(guān)心自己那樣去關(guān)心別人,你就不會犯這些錯誤中的任何一種
