Letters”沒有，希臘，字母“是想說fast, ai的深度學(xué)習(xí)課程很簡單。故選A。 （4）考查推理判斷。根據(jù)最后一段中的”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. “如果霍華德和其他人如愿以償，那么讓AI軟件開發(fā)變得更容易將會催生出一批新的不同的果實(shí)。由此推斷簡化軟件開發(fā)可能會導(dǎo)致意料之外的結(jié)果。故選D。 【點(diǎn)評】本題考點(diǎn)涉及細(xì)節(jié)理解，句義猜測和推理判斷三個(gè)題型的考查，是一篇科研類閱讀，要求考生準(zhǔn)確掌握細(xì)節(jié)信息，同時(shí)根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，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 t
