But will we notice them?”能改變未來的天才少年已經(jīng)出現(xiàn)了，但我們能不能發(fā)現(xiàn)他們呢？由此可判斷文章采用了總分總結(jié)構(gòu)，介紹了如何發(fā)現(xiàn)天才少年，故選A。 【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，是一篇教育類閱讀，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。9．閱讀理解 Slowly but surely we39。re moving closer and closer to 5G world. From smarthome security to selfdriving cars, all the internetconnected devices in your life will be able to talk to each other at lightningfast speeds with reduced delay, Objectively speaking, the fastest 4G download speeds in the U. S. top out at an average of Mbps. But by parison 5G promises gigabit (千兆) speeds. 5G is one of those signs, along with artificial intelligence, of this ing data age, said Steve Koenig, senior director of market research for the Consumer Technology Association. The selfdriving vehicle is a great emblem of this data age, and that is to say, it is a sign of time, because with one single task, driving, you have massive amounts of data ing from the vehicle itself, and a variety of sensors are collecting a lot of information to model its environment as it moves. It39。s pulling in data from other vehicles about road conditions down the lane. It could be weather information, but also connected infrastructure (基礎(chǔ)設(shè)施) construction. There39。s lots of data behind that task, which is why we need high speed. Augmented reality glasses and virtual headset haven39。t yet broken the mainstream, but tech panies are joyfully betting that these devices will eventually replace our smartphones. With 5G, that could actually happen. This is notable because panies such as Apple are reportedly developing AR glasses to assist — or perhaps even replace — smartphones. Ericsson stated at February39。s Mobile World Congress how smart glasses could bee faster and lighter with a 5G connection, because instead of being weighed down with ponents, the glasses could rely on hardware for processing power. But don39。t get too excited. There39。s still a lot of work to be done in the meantime, including various trials to make sure the radios play nicely with hardware and infrastructure construction so 5G isn39。t concentrated only in big cities.（1）What does the author want to stress in Paragraph 1? lightingfast speed of 5G. expectation of 5G world. difference between 4G and 5G. internetconnected devices in our life.（2）What does the underlined word emblem in Paragraph 2 mean? ....（3）We can infer from the text that ________. world won39。t e without AR glasses helps to create the artificial intelligence vehicle pany is developing AR glasses worldwide panies will face the fact that smartphones may be replaced（4）What will the author probably tell us next? to fully expand 5G coverage. glasses will bee faster and lighter. 5G isn39。t concentrated in big cities. importance of infrastructure construction.【答案】 （1）A（2）C（3）D（4）A 【解析】【分析】本文是一篇說明文，隨著科技的不斷發(fā)展，5G時(shí)代即將來臨。它最大的優(yōu)勢就是上網(wǎng)速度大大加快。 （1）考查推理判斷。第一段提出5G時(shí)代即將來臨，接下來介紹5G上網(wǎng)下載的高速度，相比于目前的4G，5G有望達(dá)到千兆的上網(wǎng)速度。作者在第一段想強(qiáng)調(diào)5G的超級(jí)速度。故選A。 （2）考查詞義猜測。根據(jù)第二段中的“and that is to say, it is a sign of time”也就是說，這是時(shí)間的標(biāo)志）是對(duì)前面的補(bǔ)充說明?？赏浦?，劃線詞的意思是“標(biāo)志，象征”。故選C。 （3）考查推理判斷。根據(jù)第三段中的“This is notable because panies such as Apple are reportedly developing AR glasses to assist — or perhaps even replace — smartphones.”這一點(diǎn)值得注意，因?yàn)閾?jù)報(bào)道，蘋果(Apple)等公司正在開發(fā)增強(qiáng)現(xiàn)實(shí)眼鏡，以幫助——甚至取代——智能手機(jī)）可知，我們可以從文中推斷，科技公司將面臨智能手機(jī)可能被取代的事實(shí)。故選D。 （4）考查推理判斷。根據(jù)最后一段中的“But don39。t get too excited. There39。s still a lot of work to be done in the meantime, including various trials to make sure the radios play nicely with hardware and infrastructure construction so 5G isn39。t concentrated only in big cities.”但是不要太激動(dòng)。與此同時(shí)，仍有很多工作要做，包括各種試驗(yàn)，以確保收音機(jī)能很好地配合硬件和基礎(chǔ)設(shè)施建設(shè)，這樣5G就不會(huì)只集中在大城市，可知，作者接下來可能會(huì)告訴我們“如何全面擴(kuò)大5G覆蓋?！惫蔬xA。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，詞義猜測和推理判斷三個(gè)題型的考查，是一篇科技類閱讀，考生需要準(zhǔn)確掌握細(xì)節(jié)信息，并根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。10．閱讀理解 Metro Pocket Guide Metrorail(地鐵) Each passenger needs a farecard to enter and go out.
