astheMoon—coldandlifeless.沒有它,地球就會和月球一樣—寒冷且沒生命。Wecanreusethingsforthesame

purposeasbefore...我們可以像以前一樣以同樣的用途重新使用物品……解析：thesameas...意為“與……一樣”,該短語可以拆開使用，即：thesame...as...，same后面接名詞，意為“像……一樣的……”。例如：我的書包跟你的一樣。Myschoolbagisthesameasyours.我有一個像這樣的書包。Ihavethesameschoolbagasthis.LanguagePoints2.Toomuchofthisgaspollutestheatmosphere,andcausesittokeepintoomuchheat.太多的這種氣體會污染大氣層，導致它保存了太多的熱量。keepin在本句意為“貯存；儲備”，相當于動詞store。例如：我們已經儲存了一些食物以備緊急之用。

Wehavekeptinsomefoodforanemergency.3.Asaresultofthegreenhouseeffect,the

Earth’stemperatureisincreasing.由于溫室效應，地球的溫度正在上升。解析：asaresultof意為“由于”，可與because

of互換。asaresult意為“結果；因此”，表示結果，常置于句首。例如：他因車禍而受了傷。Hewashurtasaresultofthecar

accident.=Hewashurtbecauseofthecar

accident.結果是他測驗不及格。Asaresult,hefailedthetest.4.Ifwejustlearntoliveinnewanddifferentways,wecanmakeadifference.如果我們學會用新的和不同的方式生活，我們就能起作用。解析：makeadifference意為“有影響；有作用”，其反義短語為makenodifference意為“沒影響；沒作用；沒差別”。例如：你選哪一個至關重要。Whichoneyouchoosewillmakeadifference.他來不來對我沒影響。
