【正文】 We still need someone to look after robots in the future.D.Robots will create more and better jobs for people in the future.【答案】 （1）B（2）A（3）C（4）A 【解析】【分析】本文是一篇說明文，隨著機(jī)器人被越來越多的應(yīng)用，照看機(jī)器人的工作也隨之發(fā)生了變化。本文以對(duì)相關(guān)信息進(jìn)行了介紹說明。 （1）考查細(xì)節(jié)理解。根據(jù)第一段中的The robot, created by a startup called Starship Technologies in 2014, is basically a cooler on wheels。 it uses radars, sensors, and nine cameras to make deliveries.可知，這款機(jī)器人是2014年由一家名為Starship Technologies的初創(chuàng)公司制造的，它基本上是一種車輪上的冷卻器；它使用雷達(dá)、傳感器和9臺(tái)攝像頭進(jìn)行配送。也就是說，Starship Technologies公司創(chuàng)造的是一款配送物品的機(jī)器人。故選B。 （2）考查詞義猜測。根據(jù)第二段中的which include maintenance, engineering and programming列舉了照看機(jī)器人的工作范疇，故選A。 （3）考查細(xì)節(jié)理解。根據(jù)最后一段中的A huge number of jobs will be produced as autonomous vehicles are released into the environment可知，隨著自動(dòng)化車輛被投放到市場，將產(chǎn)生大量的就業(yè)機(jī)會(huì)。故選C。 （4）考查句義理解。該劃線句子的字面意思是：機(jī)器人保姆可能會(huì)覺得自己已經(jīng)獲得了未來的工作，但事實(shí)上，他們的位置可能會(huì)更好。根據(jù)字面意思，不難看出其隱藏的意思為：機(jī)器人保姆占據(jù)很大的優(yōu)勢，他們可以在未來作更好的工作。故選A。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，詞義猜測和句義猜測三個(gè)題型的考查，是一篇科普類閱讀，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，歸納，從而選出正確答案。7．閱讀理解 Some people sit outside for hours without getting bitten by mosquitoes, but it always seems like you39。re being eaten alive within minutes of stepping outdoors. If this is you, you39。re not alone. According to Smithsonian Magazine, around 20 percent of people in the world are especially tasty to mosquitoes. What about these people makes mosquitoes39。 mouths water? A popular myth claims that mosquitoes prefer certain blood types, but the fact is that they simply can39。t tell what your blood type is from a faraway place. Jonathon Day, a professor of medical entomology (昆蟲學(xué)) at the University of Florida in the US, told NBC it39。s not plicated. The two most important reasons a mosquito is attracted to you have to do with sight and smell. Mosquitoes are especially active in the late afternoon. While flying along, they use their sense of smell to find possible targets. They find victims (攻擊對(duì)象) by smelling the carbon dioxide (CO2) breathed out by humans and animals. That39。s why you monly find them in crowded streets and parks. Joop van Loon, an entomologist at Wageningen University in the Netherlands, told Live Science, Mosquitoes start orienting (使......朝向) themselves to carbon dioxide and keep flying upwind as they sense higher concentrations (濃度). As a result, people who simply exhale (呼出) more of the gas over time – generally, larger people – have been shown to attract more mosquitoes than others. This is why kids don39。t get bitten as much ... as adults, US professor Ted Rosen told Science Alert. This love for CO2 can also put pregnant women at increased risk for mosquito bites, as they tend to exhale 21 percent more CO2 than people of the same age and size who aren39。t pregnant. In addition to carbon dioxide, the color of the clothes you wear also plays a role in attracting mosquitoes. According to Live Science, mosquitoes can lock onto targets from up to 50 meters away. At this distance, what we wear has a huge effect. Due to their vision (視覺), people wearing dark colors are more likely to bee targets. Being bitten by mosquitoes is annoying, but don39。t worry. Some simple tips can help ward them off. Scientists remend that we use insect repellent (驅(qū)蟲劑) and wear lightcolored clothing.（1）How do mosquitoes locate their targets, according to the article? seeking out bright clothes. identifying different blood types. sensing an increase of carbon dioxide. following bigger crowds.（2）Why are pregnant women more likely to be bitten by mosquitoes? larger size helps mosquitoes to see them. breathe out more CO2. are more likely to sweat. body temperatures are higher.（3）How does the article advise you to avoid mosquitoes? regularly. lightcolored clothing. your skin dry and clean. indoors in the evening.（4）What39。s the article mainly about? new finding about mosquitoes. people can avoid mosquito bites. popular myth about mosquitoes. some people are more attractive to mosquitoes than others.【答案】 （1）C（2）B（3）B（4）D 【解析】【分析】本文是一篇說明文，介紹了為什么有些人可以整個(gè)夏天坐在戶外乘涼卻不被蚊子叮咬，而有些人一出門就好像要被蚊子吃掉一樣。 （1）考查細(xì)節(jié)理解。根據(jù)第四段中的“While flying along, they use their sense of smell to find possible targets. They find victims by smelling the carbon dioxide (CO2) breathed out by humans and animals. ”飛的時(shí)候，它們用嗅覺發(fā)現(xiàn)目標(biāo)。它們通過聞人和動(dòng)物呼出的二氧化碳來鎖定目標(biāo)；以及第五段中的“Mosquitoes start orienting themselves to carbon dioxide and keep flying upwind as they sense higher concentrations”蚊子開始飛向有二氧化碳的地方，當(dāng)它們感知到高濃度的二氧化碳時(shí)，就保持逆流飛行，可知，蚊子通過感知二氧化碳的增加來鎖定目標(biāo)。故選C。 （2）考查細(xì)節(jié)理解。根據(jù)第七段“This love for CO2 can also put pregnant women at increased risk for mosquito bites, as they tend to exhale 21 percent more CO2 than people of the same age and size who aren39。t pregnant.”對(duì)二氧化碳的喜歡使得孕婦很容易被蚊子咬，因?yàn)樗齻儽日Ｏ嗤挲g，相同體型的人呼出多余21%的二氧化碳，可知，孕婦呼出更多的二氧化碳，所以更招蚊子咬。故選B。 （3）考查細(xì)節(jié)理解。根據(jù)最后一段中的“Scientists remend that we use insect repellent and wear lightcolored clothing.”科學(xué)家建議我們使用驅(qū)蟲劑或者穿淺顏色的衣服?？芍恼陆ㄗh我們可以通過穿淺色衣服來避免蚊子叮咬。故選B。 （4）考查主旨大意。根據(jù)第二段中的“According to Smithsonian Magazine, around 20 percent of people in the world are especially tasty to mosquitoes. What about these people makes mosquitoes39。 mouths water?”根據(jù)Smithsonian雜志，世界上大約20%的人容易招蚊子咬。為什么這些人非常吸引蚊子呢？可知，本文探討的話題是：為什么一些人比其他人更容易招蚊子。故選D。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解和主旨大意兩個(gè)題型的考查，是一篇科研類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，并根據(jù)上下文的邏輯關(guān)系，進(jìn)行概括和歸納，從而選出正確答案。8．閱讀理解 Benefits and Problems of Genetic Engineering Plant breeding is the science of changing the characteristics of plants in order to produce desired ones. Genes in a plant are what determine what type of characteristics it will have. Plant breeders try to create a specific oute of plants and potentially new plant varieties by changing the genes of the plants through breeding, which is making new plants from parents of different varieties or species. Actually, plant breeding has been practiced for thousands of years, since near the beginning of human civilization. It is practiced worldwide by individuals such as gardeners and farmers and by professional plant breeders employed by organizations such as government institutions, universities, cropspecific industry associations or research centers. They have crossbre
