答案 D

解析 推理判断题。根据第一段内容可知，作者不明白自己为什么要开垦一个菜园并自己种菜。每年四月份作者看着土地一片狼藉，就会下决心不再种菜。但当某天早晨作者刚睡醒，不可避免地呼吸着从菜园飘来的清新空气，看着温暖的阳光洒在地毯上，作者却很开心，再结合第二段第一句“Itisnotonlypleasuresendingmebacktostareatthatplotofsoil...”可推知，作者喜欢春天时的这个菜园。故选D。 5.Whatdrovetheauthortoabandonplastic? A.Highprice.

B.Environmentalconcern. C.Poorfunction. D.Personalpreference. 答案 D

解析 细节理解题。根据第二段倒数第三句中的“Butplasticlookssoindustrial，sounromantic”和第二段最后一句“Besides，itlookslovelyandcomestousfree.”可知，作者不再使用塑料是出于个人的喜好。故选D。

句，

“Wheneverlifeseemspointlessanddifficulttograsp

youcanalwaysgetoutinthegardenandgetsomethingdone.”可知，在生活无望或者难以掌控的时候，你总是可以在菜园找到事情做，由此可推知，作者认为种菜的乐趣是精神上的，是因为种菜能带来精神上的满足，故选D。 7.Whatisthebesttitleforthetext? A.ToGardenorNot B.WhatIGardenfor C.HowtoGarden D.WisdomfromGardens 答案 B
