。土地中迅速生長出來。output”輸出"；trend"趨勢".30.B【解析】參見上題解析.shootup”迅速生長"符合語境.comeaway"離開，脫落”；getaround"四處走動，傳播"；setout”出發(fā)”。31.A【解析】結(jié)合上文的"thebarebranchesoftrees”可知，此處表示”黑暗的土地中".muddy”泥濘的”；expansive”廣闊的”；fragile”脆弱的".32.D【解析】綠色吸引著我們脫掉（takeoff)一層又一層的衣服，去見識外面的(outside）世界。pickout”挑選”；dealwith"處理"。33.B【解析】參見上題解析。下文中的”。.。outsidejusttosniffthespringair"亦是暗示。34。C【解析】根據(jù)語境可知，此處指綠色不是以令人心煩意亂的方式而是(but）伴隨著悠閑的興奮，吸引（draws）我們到外面嗅嗅春天的空氣。35。B【解析】參見上題解析。recommend"推薦”；force"迫使”；distract”使……分心”。36。D【解析】根據(jù)上文的"Unlikealmostanyothercolor，greenseemstohaveitsownsmell"可知，綠色似乎有專屬于自己的味道，這種味道是太陽和天空的迷人的混合物(combination）。distinction”區(qū)別”；connection”聯(lián)系";appearance”外觀"。37.C【解析】綠色的春天的美景讓我們駐足，提醒我們要感恩(appreciate)我們還活著。share”分享”；accumulate"積累”；evaluate"評估".38。A【解析】根據(jù)下文中的”withoutbecomingoverlyattachedtoonepartinit”可知，綠色也使我們要注重成長的整體進程（process），恰當(dāng)?shù)?appropriately)培養(yǎng)我們自身，而不是只關(guān)注其中的一個部分.ability”能力"；quality"質(zhì)量"；standard"標(biāo)準(zhǔn)”.39.C【解析】參見上題解析.occasionally"偶爾"；patiently”耐心地”;deliberately”故意地"。40。B【解析】綠色提醒我們放手，順其自然，同時又給予我們做我們自己的事的力量。while”與……同時”符合語境。第二節(jié)【文章大意】本文是一篇說明文，作者介紹了家用空調(diào)的發(fā)展過程。41。by【解析】考查介詞。該空前面的wasinvented說明該句是被動語態(tài)，WillisCarrier是動作的執(zhí)行者，故在其前加介詞by。42。invention【解析】考查名詞。形容詞性物主代詞his之后應(yīng)用名詞，故用invent的名詞invention.43.it45.wereequipped【解析】考查時態(tài)語態(tài)。由結(jié)構(gòu)可知，該空是句子的謂語動詞；敘述過去的事情應(yīng)用一般過去時；且句子主語復(fù)數(shù)名詞manyhomes與equip是被動關(guān)系，故
