A mission to Mars is no laughing matter. On average, the red planet is 140 million miles (225 million kilometers) away from Earth. A trip there would take around eight months in a small spacecraft. And Mars has a munications delay of 20 minutes. This means that astronauts will have to wait 20 minutes for a reply, when an emergency happens.NASA has a new job listing, and it39。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，推理判斷和主旨大意三個(gè)題型的考查，是一篇科技類(lèi)閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，同時(shí)根據(jù)上下文進(jìn)行邏輯推理，概括歸納，從而選出正確答案。再根據(jù)最后一段中的“The next step in the research will be to test RAS39。 （4）考查主旨大意。 （3）考查推理判斷。根據(jù)最后一段中的“The next step in the research will be to test RAS39。根據(jù)章第二段中的“ The Robot Activity Support System, or RAS, uses sensors （傳感器）equipped in a WSU smart home to determine where its residents are, what they are doing and when they need assistance with daily activities”可知機(jī)器人活動(dòng)支持系統(tǒng)（RAS）使用WSU智能家居中配備的傳感器（傳感器）來(lái)確定其居民在哪里，他們?cè)谧鍪裁匆约昂螘r(shí)需要日?；顒?dòng)的幫助，說(shuō)明傳感器起到了重大的作用，故選A。Older adults have benefited from RAS.【答案】 （1）A（2）B（3）C（4）B 【解析】【分析】本文是一篇說(shuō)明文，介紹了一款由美國(guó)華盛頓州立大學(xué)的科學(xué)家們研發(fā)的機(jī)器人，可以幫助那些癡呆或有身體缺陷的老年人在家里過(guò)上自立的生活。Smart Home Tests first elderCare robot.C.Elderly people leave the nursing home.D.Optimistic.B.Doubtful.s Minor39。D.It can locate people and do any task.B.Through their daily activities.（2）What can we know about RAS? A.Through a mobile robot.B.Through sensors. While we are still in an early stage of development, our initial results with RAS have been promising, Minor said. The next step in the research will be to test RAS39。 Currently, an estimated 50 percent of adults over the age of 85 need assistance with every day activities such as preparing meals and taking medication and the annual cost for this assistance in the US is nearly $2 trillion. With the number of adults over 85 expected to triple by 2050, researchers hope that technologies like RAS and the WSU smart home will relieve some of the financial strain on the healthcare system by making it easier for older adults to live alone. A robot created by Washington State University (WSU) scientists could help elderly people with dementia (癡呆) and other limitations live independently in their own homes. 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，推理判斷和主旨大意三個(gè)題型的考查，是一篇科研類(lèi)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。 （4）考查主旨大意。實(shí)驗(yàn)?zāi)康氖强纯带B(niǎo)類(lèi)的視角是否能提供幫助。 （3）考查推理判斷。根據(jù)最后一段中的“It seemed that the strikingly iridescent surfaces on our targets visually broke up the otherwise recognizable shape of the targets, which made them hard to distinguish.”似乎我們的目標(biāo)上驚人的彩虹表面在視覺(jué)上打破了原本可以辨認(rèn)的目標(biāo)形狀，這使得它們很難區(qū)分。t a new one.”引人注目的顏色可以用來(lái)偽裝，這種想法并不新鮮，排除C，故選D。catching colors could be used as a cover173。根據(jù)第一段中的“A good disguise keeps you hidden, right? Well, sometimes the best disguise is actually the most dazzling because research reveals that flashy metallic iridescence(金屬彩虹色) can visually puzzle predators, which allows colorful prey to survive another day.”可知彩虹色被動(dòng)物用來(lái)通過(guò)逃離捕食者而活得更久，排除A；根據(jù)第三段中的“Here I would like to point out that in some species, particularly those that display strong sexual dimorphism(雌雄兩性), such as birds of paradise or some butterflies or fishes, the occurrence of iridescence is most likely driven by sexual selection.”在這里我想指出的是，在某些物種中，尤其是那些表現(xiàn)出強(qiáng)烈兩性差異的物種，比如天堂鳥(niǎo)、孔雀，甚至在某些蝴蝶或魚(yú)類(lèi)中，彩虹色的出現(xiàn)很可能是由性別選擇所驅(qū)動(dòng)的。Shining colors as a sexual strategy【答案】 （1）D（2）C（3）C（4）B 【解析】【分析】本文是一篇說(shuō)明文，介紹了彩虹色有助于生物隱藏。Metallic iridescent as the best disguiseC.A famous camouflage strategyWhy birds are not effected by iridescent insects.D.Whether there are any differences between bees and birds.B.If a circle, with a sugar reward, is iridescent, the bees may have difficulty finding itD.Bees can always tell the difference between a circle and an ovalB.D.catch the attention of their matesC.live a little longer by escaping their predator(捕食者)s173。s concealment？ s concealment39。Coloration in the Animal Kingdom, already in 1909, that 39。up isn39。 The idea that eye173。 And in our research group we are of course interested in why this vivid metallic color is so widespread in nature. Karin Kjernsmo of the University of Bristol adds that in some cases the showy splashes of light are a sexual strategy. Here I would like to point out that in some species, particularly those that display strong sexual dimorphism(雌雄兩性), such as birds of paradise or some butterflies or fishes, the occurrence of iridescence is most likely driven by sexual selection. For example, in many of these cases it is the males that have these vivid iridescent colors and they use them in mate choice or they use them as a signal to attract mates.
