Manpower is always needed to check bags and we want to develop a method to try to reduce manpower.”在大型公共場(chǎng)所，很難像機(jī)場(chǎng)那樣設(shè)置昂貴的安檢設(shè)施。檢查行李總是需要人力，我們希望開發(fā)一種互補(bǔ)的方法來減少人力，可推知選A。 （4）考查詞義猜測(cè)。根據(jù)最后一段中的“Future work will continue to focus on ameliorating the accuracy of identifying objects and imaging shapes and volumes”今后的工作將繼續(xù)側(cè)重于提高識(shí)別物體和成像形狀及體積的準(zhǔn)確性，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)，推理判斷和段落大意四個(gè)題型的考查，是一篇科研類閱讀，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．犇犇閱讀理解 In my memory, winters always used to be really unpleasant. 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 ? A.Fix an air conditioner.B.Take a hot bath.C.Run a lot.D.Put on more clothes.（2）How does electronic thermal clothing work? A.The equipment placed inside the clothing produces heat.B.It needs to be warned up before being used.C.The thermostat heat up automatically when the temperature is low.D.It keeps warm for over 12 hours after being charged fox an hour.（3）From the passage, we can lean the following statements EXCEPT that ________. A.Tado39。s model can be controlled by saying something to itB.with the inbuilt speaker and microphone, Beanies and Earmuffs users can have a phone callC.technology can do nothing to make winter less roughD.Bluetooth technology is used in the clothing for the head（4）What39。s the best title of this passage? A.A Smart ThermostatB.A Modern winterC.Ways of keeping warmD.An unpleasant winter【答案】 （1）D（2）A（3）C（4）B 【解析】【分析】本文是一篇說明文，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In my memory, winters always used to be really unpleasant. 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
