Anunpleasantwinter【答案】（1）D（2）A（3）C（4）B【解析】【分析】本文是一篇說(shuō)明文，在科技并不發(fā)達(dá)的過去，人們可能會(huì)為如何在嚴(yán)寒天氣里更好地保暖而倍感困擾?，F(xiàn)如今，每到嚴(yán)冬時(shí)節(jié)，雖然溫度驟降、天氣惡劣，但隨著各類智能保暖產(chǎn)品的問世，冬天也能變得舒適宜人。人們憑借科學(xué)技術(shù)發(fā)明了各式各樣的防寒方法。比如，用智能電子設(shè)備調(diào)節(jié)屋內(nèi)和衣物的溫度；使用無(wú)線科技制造會(huì)自動(dòng)發(fā)熱的服飾。（1）考查詞義猜測(cè)。根據(jù)第一段中的"Inmymemory,wintersalwaysusedtobereallyunpleasant.Youhadtobundleupjusttokeepwarmwhenyouwentoutside."可知，在我的記憶中，冬天總是很不令人愉快。你外出時(shí)必須穿得暖和一點(diǎn)。所以通過"keepwarm"可知，外出時(shí)要想暖和一些，就要多穿衣服。故判斷出第1段中帶下劃線的單詞"bundleup"是多穿點(diǎn)衣服。故選D。（2）考查細(xì)節(jié)理解。根據(jù)第四段中的"Atthetouchofabutton,orthroughanapponourphones,theclothinggeneratesheatfromelementsplacedinside."可知，只要按下按鈕，或者通過手機(jī)上應(yīng)用程序，安裝在衣服內(nèi)部的電子元件就會(huì)產(chǎn)生熱量。所以電子保暖服裝工作的原理是安裝在衣服內(nèi)部的電子元件產(chǎn)生熱量。故選A。（3）考查細(xì)節(jié)理解。根據(jù)第二段中的"Fortunately,thingsdon'thavetobesochallenginganymore.Technology,engineringanddesignhaveadvancedgivingusnewsolutionstooldproblems"可知，幸運(yùn)的是，事情不需要再這么有挑戰(zhàn)性了。先進(jìn)的技術(shù)、引擎環(huán)和設(shè)計(jì)為我們提供了解決老問題的新方法。所以C選項(xiàng)"科技無(wú)法讓冬天變得不那么難熬"不符合短文說(shuō)明的內(nèi)容。故選C。（4）考查主旨大意。通讀全文可知，在科技并不發(fā)達(dá)的過去，人們可能會(huì)為如何在嚴(yán)寒天氣里更好地保暖而倍感困擾。現(xiàn)如今，每到嚴(yán)冬時(shí)節(jié)，雖然溫度驟降、天氣惡劣，但隨著各類智能保暖產(chǎn)品的問世，冬天也能變得舒適宜人。人們憑借科學(xué)技術(shù)發(fā)明了各式各樣的防寒方法。比如，用智能電子設(shè)備調(diào)節(jié)屋內(nèi)和衣物的溫度；使用無(wú)線科技制造會(huì)自動(dòng)發(fā)熱的服飾。所以短文的最佳標(biāo)題為"讓現(xiàn)代科技溫暖你的冬日"。故B選項(xiàng)"讓現(xiàn)代科技溫暖你的冬日"符合題意。故選B。【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，詞義猜測(cè)和主旨大意三個(gè)題型的考查，是一篇科普類閱讀，要求考生在捕捉細(xì)節(jié)信息的基礎(chǔ)上，進(jìn)一步根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，概括和歸納，從而選出正確答案。5．Directions:Choosetheonethatfitsbestaccordingtotheinformationgiveninthepassageyouhavejustread.
