You had to bundle up just to keep warm when you went outside. You were often cold, wet, slip on the ice, and you39。d arrive home to an icecold house. And that would mean turning on the heating and waiting. It39。s a miracle you didn39。t get cold to the bone. Fortunately, things don39。t have to be so challenging any more. Technology, engine ring and design have advanced giving us new solutions to old problems. It means dealing with winter needn39。t be like skating on thin ice. With a smart thermostat (溫度自動(dòng)調(diào)節(jié)器), our homes can be warm when we need them to be. Many models feature smartphone apps that allow you to control temperature remotely, so we can warm up the house before we arrive home. According to , Tado39。s model features voice control, while the Nest 39。leans39。 your habits and automatically heats the home for you. Clothes have been given an upgrade, too. Electronic thermal jackets, sweaters and coats heat up when you turn them on. What better way to keep warm in the dead of winter? At the touch of a button, or through an app on our phones, the clothing generates heat from elements placed inside. Many models offer three levels of heating which stay warm for over 12 hours. . Finally, there is the clothing for the head, beanie s and Earmuff, that feature speakers included in the fabric using Bluetooth technology so we can listen to our favourite music or, in some cases, have a phone callusing the inbuilt microphone. All while keeping the head warm and avoiding a cold. For many, the thought of winter used to be enough to make their blood run cold. But using technology, life needn39。t freeze up. With the right solutions, there39。s no reason why winter can39。t be really, really cool.（1）What do the underlined words bundle up mean in ?

You had to bundle up just to keep warm when you went outside. 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 keep warm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bundle up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 At the touch of a button, or through an app on our phones, the clothing generates heat from elements placed inside. 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, things don39。t have to be so challenging any more. Technology, engine ring and design have advanced giving us new solutions to old problems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)科技無法讓冬天變得不那么難熬不符合短文說明的內(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?，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】本題考點(diǎn)涉及細(xì)節(jié)理解，詞義猜測和主旨大意三個(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．犇犇Choose the one that fits best according to the information given in the passage you have just read. Escaping predators (食肉動(dòng)物), digestion and other animal activities—including those of humans—require oxygen. But that essential ingredient is no longer so easy for marine life to obtain, several new studies reveal. In the past decade ocean oxygen levels have taken a dive—an alarming trend that is linked to climate change, says Andreas Oschlies, an oceanographer at the Helmholtz Center for Ocean Research in Germany, whose team tracks ocean oxygen levels worldwide. We were surprised by the intensity of the changes we saw, how rapidly oxygen is going down in the ocean and how large the effects on marine ecosystems are, he says. It is no surprise to scientists that warming oceans are losing oxygen, but the scale of the drop calls for urgent attention. Oxygen levels in some tropical (熱帶的) regions have dropped by an astonishing 40 percent in the last 50 years, some recent studies reveal. Levels have dropped less significantly elsewhere, with an average loss of 2 percent globally. A warming ocean loses oxygen for two reasons: First, the warmer a liquid bees, the less gas it can hold. That is why carbonated drinks go flat faster when left in the sun. Second, as polar sea ice melts, it forms a layer of water above colder, more salty sea waters. This process creates a sort of lid that can keep currents from mixing surface water down to deeper depths. And because all oxygen
