【正文】 育工作者。故選D。 （4）考查主旨大意。根據(jù)第一段中的“While the start of a new school year is always exciting, this year was even more so for some elementary school students in Auckland, New Zealand. They became the world39。s first kids to be “taught” by a digital teacher”可知，從新學年開始，新西蘭奧克蘭的小學生將成為世界上第一批被機器人老師教的孩子。之后文章就此展開，由此可推斷出he World39。s First Digital Teacher Appears in Classroom最符合本文的標題。故選B。 【點評】本題考點涉及細節(jié)理解，推理判斷和主旨大意三個題型的考查，是一篇科教類閱讀，要求考生在捕捉細節(jié)信息的基礎上，進一步根據(jù)上下文的邏輯關系，進行分析，推理，概括和歸納，從而選出正確答案。7．犇犇閱讀理解 In areas like the Central United States that get lots of tornadoes, there39。s a mon piece of celestial （天上的）fortunetelling that green skies mean a tornado is on its way. Research has shown that it isn39。t quite as simple as that, but scientists have found that if you see a green sky, you should probably go inside. As far as most scientists can tell, the green skies around powerful thunderstorms are usually a bination of red sunsets and water droplets. Daytime skies are blue because blue shorter wavelengths of visible light tend to bounce off （反射）air molecules better than red longer wavelength light. So the blue light gets bounced all over the sky and looks like it39。s ing from everywhere. Meanwhile, around sunset sunlight travels through so much atmosphere that just about all the blue is bounced away from the horizon, leaving all those reds and oranges behind. The sunset might look exclusively （獨有的）red and orange, but there39。s still some green and even blue light hidden in there, just far less than the other colors. But for us to notice the remaining green light, it needs to hit something that reflects green light much better than red. That39。s where water es in. Big tall threatening storm clouds are made of water droplets, and even though water is best at reflecting blue light, it can still reflect green pretty well, much better than reds and oranges, so under just the right conditions, the water in and around a cloud can bounce the green light hidden in the sunset right into our eyes making the sky look green. Still, none of the conditions that can turn skies green are unique to the clouds that produce tornadoes. Sometimes they just lead to lots of rain, and maybe some hail. So if you see huge storm clouds rolling in and a green tint （色調(diào)）in the sky, it doesn39。t necessarily mean there39。s about to be a tornado, but it does mean you should probably head indoors.（1）What can be the best title for the text?

Sometimes they just lead to lots of rain, and maybe some hail.”可知，本文主要話題是關注綠色的天空是否意味著即將來臨的龍卷風展開的，故選B。 （2）考查細節(jié)理解。根據(jù)第二段中的“Daytime skies are blue because blue shorter wavelengths of visible light tend to bounce off （反 射）air molecules better than red longer wavelength light.”可知，白天天空是藍色,因為藍色短的波長的可見光會反射空氣分子比紅色的長波長光。故選C。 （3）考查代詞指代。根據(jù)第二段中的“The sunset might look exclusively （獨有的）red and orange, but there39。s still some green and even blue light hidden in there, just far less than the other colors.”可知，選A。 （4）考查推理判斷。根據(jù)第三段中的“But for us to notice the remaining green light, it needs to hit something that reflects green light much better than red. That39。s where water es in.”可知，水既能反射藍光，也能反射紅光，故選B。 【點評】本題考點涉及細節(jié)理解，代詞指代，推理判斷和主旨大意四個題型的考查，是一篇科普類閱讀，要求考生在捕捉細節(jié)信息的基礎上，進一步根據(jù)上下文的邏輯關系，進行分析，推理，概括和歸納，從而選出正確答案。8．犇犇閱讀理解 Threequarters of the world39。s coffee farms destroy forest habitat to grow coffee in the sun and typically use harmful pesticides (殺蟲劑) and chemicals that poison the environment. When forests disappear, migratory (遷徙的) songbirds disappear, too. In order to deal with severe population and habitat loss, Smithsonian scientists created the Bird Friendly certification. Bird Friendly coffees are shadegrown, meaning the coffee is planted under trees, rather than on the land that has been cleared of all other plants. Coffee experts say shadegrown coffees taste better, because the beans ripen slower than coffee grown in the full sun, resulting in a richer, more plex flavor. Bird Friendly certified coffees grow under biodiverse shade that provides habitat for migratory songbirds and other wildlife, stores carbon and fights climate change. Bird Friendly coffees are also certified organic, meaning they are grown without pesticides, which is better for people and for the planet. Bird Friendly producers can also earn more for their crops. The wood and fruit trees on shade coffee farms provide farmers with additional ine. Every cup of Bird Friendly coffee purchased rewards these farmers with a little more money for being good stewards of the environment and encourages them to continue conserving Bird Friendly habitat. Buying Bird Friendly supports the Smithsonian Migratory Bird Center39。s conservation research aimed at understanding and protecting your feathered friends. You can purchase Bird Friendly certified coffees around the world and protect wildlife and habitat with every cup. Find a store or cafe near you, or better yet, have it shipped t
