Some experts worry that this will serve only to create a flood of unreliable AI systems which will be useless at best and dangerous at worst. In the earliest days of the Internet, only a select few nerds, namely puter holies with specific skills, could build applications. Not many people used them. Then the invention of the World Wide Web led to an explosion of web pages, both good and bad. But it was only by opening up to all that the Internet gave birth to online shopping, instant global munications and search. If Mr. Howard and others have their way, making the development of AI software easier will bring forth a new crop of fruit of a different kind.（1）What can we learn about deep learning? A.s course can be pleted in just seven weeks. That is changing. The standard route into these jobs has been a PhD in puter science from one of America39。7．閱讀理解 Learning, Fast and Deep故選B。這種降落方式的一個(gè)缺點(diǎn)是蝙蝠經(jīng)常用力降落，這可能會(huì)導(dǎo)致疼痛。 （4）考查推斷判斷。由此可知，此處的it指的是飛行的方向。 （3）考查代詞指代。 （2）考查推理判斷。綜上所述，可知，蝙蝠與鳥(niǎo)運(yùn)動(dòng)方式的不同是本文的主題。第二段用研究證明過(guò)去認(rèn)為蝙蝠和鳥(niǎo)類在飛行運(yùn)動(dòng)方面沒(méi)有什么區(qū)別是錯(cuò)誤的。 （1）考查主旨大意。Bats and birds land in different ways.【答案】 （1）D（2）C（3）C（4）B 【解析】【分析】本文是一篇議論文，作者用研究事實(shí)來(lái)證明蝙蝠在飛行及運(yùn)動(dòng)方式與鳥(niǎo)類完全不同。Bats can adjust speed before landing.B.Bats might hurt themselves when landing.D.the flying directionB.They hide in tree branches.（3）The word it (in 2nd paragraph) probably refers to ______.

A.Why scientists have difficulty observing bats.C. these will vary depending on the area where a bat species makes its home. For example, a cave bat, which regularly lives on a hard stone ceiling, is more careful about its landing preparation than a bat more accustomed to landing in leafy treetops.（1）Which of the following is the topic of the passage? A. In the past it was believed that, in terms of flying mechanics, there was little difference between bats and birds. This belief was based only on assumption, however, because for years nobody had actually studied in detail how bats move their wings. In recent years, though, researchers have discovered a number of interesting facts about bat flight. Bats are built differently from birds, and their wings are made up of both their front and hind limbs (肢體). This makes coordinating (協(xié)調(diào)) their limbs more difficult for bats and, as a result, they are not very good at flying over longer distances. However, they are much better at the ability to adjust themselves: a bat can quickly change its direction of flight or pletely reverse it, something a bird cannot easily do.6．犇犇Choose the one that fits best according to the information given in the passage you have just read. 第一段中的“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.”有時(shí)，最好的偽裝其實(shí)是最耀眼的偽裝，因?yàn)檠芯勘砻鳎W光的金屬彩虹色能在視覺(jué)上迷惑捕食者，這讓五顏六色的獵物能夠再存活一天，是全文的主題句，結(jié)合全文內(nèi)容，可知這篇文章主要講了彩虹色有助于生物隱藏，故選B。由此推斷接下來(lái)一段會(huì)談?wù)?為什么鳥(niǎo)類不受彩虹色昆蟲(chóng)的影響，故選C。根據(jù)最后一段說(shuō)研究人員目前正在對(duì)鳥(niǎo)類進(jìn)行實(shí)驗(yàn)，這些鳥(niǎo)類的飲食中經(jīng)常含有彩虹色的昆蟲(chóng)。故選C。 （2）考查細(xì)節(jié)理解。up isn39?？芍?jiǎng)游镉貌屎缟鹜榈淖⒁?，排除B；根據(jù)倒數(shù)第二段中的“The idea that eye173。 （1）考查細(xì)節(jié)理解。D.Colors unique to animalsB.Which camouflage theory applies more to birds.（4）Which of the following might serve as the best title of the passage?

In a similar way, we were asking whether iridescence, due to its changeability, could work as a form of camouflage by preventing shape recognition. Kjernsmo and her colleagues trained bumblebees to associate a particular shape—a circle or an oval—with a sugar reward. And they found that the bees, when given a choice, would preferentially visit the shape they knew to be sweet. But when the shapes were iridescent, the bees had trouble telling them apart. 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. As for making use of this method for hiding in plain sight, Any practical applications is of course directly linked to any industry that has an interest in camouflage, that is how to conceal objects or make them more difficult to recognize. The researchers are currently conducting experiments with birds, which often prey on iridescent insects to see if it helps to have a bird39。. And this sounds like a pletely unreasonable thing to say, because how can colors that are both brilliant and changeable contribute to animal39。brilliantly changeable or metallic colors are among the strongest factors in an animal39。t a new one. The father of camouflage theory, Abbott Thayer, really believed that iridescence should be categorized as a camouflage strategy. And he wrote in his famous lifework Concealing173。catching colors could be used as a cover173。But iridescence also shows up in situations where reproduction is not an issue. So what we are studying now is whether natural selection i
