解答 36-40:BEGAF.
36.B聯(lián)系上下文.根據(jù)橫線前兩句Many of us feel sleepy in winter,but other species often take it a step further and hibernate (冬眠).可知其他動(dòng)物在冬天會(huì)冬眠.橫線后句The body slows down and breathing,temperature and metabolic and heart rate all decrease.介紹冬眠的時(shí)候,動(dòng)物的身體特征.橫線句必須是連接上下文.B項(xiàng):They were hibernating underground to save energy.他們蟄伏于地下,以保存能量.符合上下文串聯(lián).故選B.
37.E上下文串聯(lián).根據(jù)橫線前兩句Hibernation seems to do them good.But human cannot bed down for long periods.可知冬眠對動(dòng)物是有好處的,而我們?nèi)祟愂遣荒芩吣敲撮L時(shí)間的.因?yàn)閯?dòng)物的冬眠是為了節(jié)約能量.E項(xiàng):Why,if it is so beneficial,do we not hibernate?既然冬眠有這么多好處,那么為什么人類不冬眠的?符合上下文串聯(lián).故選E.
38.G語境辨析題.根據(jù)橫線后句Then they live off body-fat reserves until it's time to wake up.可知冬眠的動(dòng)物依靠儲(chǔ)存在體內(nèi)的能量過冬.那么前句應(yīng)該敘述動(dòng)物在夏天努力儲(chǔ)存一定的脂肪以備冬眠消耗.(So many animals fatten themselves up during summer.)故選G.
39.A聯(lián)系上文題.根據(jù)前句But a 2015study of dormice found that they continued hibernating even when cold conditions had ended.可知睡鼠在冬天結(jié)束以后還在冬眠.那么肯定存在其他的原因,故A項(xiàng):So obviously there are other reasons.符合上下文串聯(lián).故選A.
40.F承上啟下題.根據(jù)橫線后句By staying out of sight,the dormice avoided being hunted by their predators (天敵) like owls.在介紹睡鼠繼續(xù)冬眠的其他原因.故F項(xiàng):The dormice had another reason to stay underground.起著承上啟下的作用,符合上下文串聯(lián).故選F.
點(diǎn)評(píng) 對于此類題型的解答,可以將整個(gè)文段首先瀏覽一遍,大概理解意思.答題過程中,根據(jù)所提供的答語或是后文進(jìn)行作答,同時(shí),做題過程中也可以使用排除法,將選項(xiàng)帶到文章中逐一的作答,答完后注意通讀檢查是否符合邏輯,語義順暢.

Do you drink water that's been left sitting out overnight or even for another day? Have you noticed it tastes different?
Tap water that has been left to sit out slowly begins to acquire an off taste. Many people think that this is because of microorganisms(微生物). But that's not what makes old water taste not fresh. For that we can thank carbon dioxide. After about 12 hours, tap water starts to go flat as carbon dioxide in the air starts to mix with the water in the glass, lowering its pH and giving it an off taste. But it's most likely safe to drink.
However, back to those microorganisms. If you use a dirty glass day after day, there is more of a chance of bacteria making themselves known; a risk that increases if you share the glass with another mouth as well. But assuming you use a fresh glass every few days, you probably won't have a problem unless the glass has been touched by dirty fingers, and especially if those dirty fingers went unwashed after using the bathroom.
As for plastic water bottles that have been left out in the sun or in the car, step away from the bottle, warns Dr. Kellogg Schwab, director of the Johns Hopkins University Water Institute. "A chemical called bisphenol-A, or BPA, along with other things used to make plastic can leach(過濾) into your water if the bottle heats up or sits in the sun," he explains. BPA, as you probably know, has been linked to everything from heart disease to cancer. Schwab also adds that plastic used for commercial bottled water isn't meant to be washed or refilled, so use only one time and recycle. Or don't buy them at all; use refillable water bottles instead.
