【正文】 . Other plants get ants to help them move their seeds around, by providing them with rich food packets attached to the seeds.”，有些螞蟻會偷取花蜜逃跑，但有些會留下來攻擊任何試圖傷害植物的東西。其他植物讓螞蟻幫助它們移動種子，方法是在種子上附加豐富的食物包?？芍?，第二段主要講了植物和螞蟻如何互動，故選A。 （3）考查細節(jié)理解。根據(jù)倒數(shù)第二段中的“But scientists weren39。t sure how the evolutionary relationship between ants and plants got started.”但是科學家們并不確定螞蟻和植物之間的進化關系是如何開始的。故選C。 （4）考查推理判斷。根據(jù)第一段中的“A new study has found that there is a long history of interactions between ants and plants.”一項新的研究發(fā)現(xiàn)，螞蟻和植物之間的互動有著悠久的歷史。是全文的主題句，由此推斷出，作者寫這篇文章的目的是告知讀者最新的研究結(jié)果，故選B。 【點評】本題考點涉及細節(jié)理解和推理判斷兩個題型的考查，是一篇科研類閱讀，考生需要準確掌握細節(jié)信息，并根據(jù)上下文進行邏輯推理，從而選出正確答案。6．閱讀理解 Have you ever experienced such an annoying thing as it took so long to open a web page? You39。re watching stops every few minutes, which ruined your internet experience. But it could be a thing of the past. On June 3, the Ministry of Industry and Information Technology announced that China would issue licenses for the mercialization of 5G. It means major tele carriers will start to provide 5G services. The G in 5G refers to the generation of mobile network technologies. 1G let us talk to each other, 2G let us send messages, 3G gave us mobile data and the internet, and 4G made all of these things faster. Now 5G promises much faster data download and upload speeds, and more stable connections. This means that you will be able to download an entire HD movie in seconds and only experience a short delay between sending and receiving data. For example, when you have a video chant with your friend, there is generally a 100 to 200 milliseconds (毫秒) delay with 4G, but 5G will reduce the delay to 1 millisecond or less, which is almost real time. With a 5G network, the short delay in information exchange will allow driverless cars to run more safely, as they will be able to municate in real time and avoid potential dangers. Meanwhile, 5G enabled wearable devices will keep doctors constantly updated on the health status of their patients and warn them immediately if there39。s something wrong. Besides, VR games will bee more popular with 5G. The short delay of 5G will make the games feel even more real. Though 5G will make our lives more convenient, it will not be perfect. For one thing, 5G will not travel far. On 4 networks, you can be 10 kilometers away from the nearest transmission (傳輸) base and barely lose signal. But 5G will only cover about 300 meters, meaning we will need more transmitters so that we can get signals. And in order to use 5G, we will have to buy new specially, designed for 5G that are currently expensive.（1）What is the function of the first paragraph? provide a background of the topic. offer basic knowledge of the topic. use an example to support the topic. draw readers39。 attention to the topic.（2）According to the passage, what is likely to happen to our life with 5G? can treat more patients. drivers are needed in the near future. advanced technologies will be further improved. will hate playing VR games in the real world.（3）What can he found when 5G is pared with 4G? cover smaller areas. needs more transmitters. signals can travel farther. costs higher in early stage.（4）What is the text mainly about? development of 5G. that 5G will face. that people will get from 5G. difference that 5G will make to our lives.【答案】 （1）D（2）C（3）D（4）D 【解析】【分析】本文為一篇說明文，介紹了5G時代的到來即將給人們的生活帶來的影響。 （1）考查推理判斷。根據(jù)第一段中的“Have you ever experienced such an annoying thing as it took so long to open a web page? You39。re watching stops every few minutes.”可知，第一段使用打開網(wǎng)頁時間長且卡頓的例子來吸引讀者并引出主題。故選D。 （2）考查推理判斷。根據(jù)第四段“With a 5G network, the short delay in information exchange will allow driverless cars to run more safely, as they will be able to municate in real time and avoid potential dangers. Meanwhile, 5G enabled wearable devices will keep doctors constantly updated on the health status of their patients and warn them immediately if there39。s something wrong. Besides, VR games will bee more popular with 5G. The short delay of 5G will make the games feel even more real.”可知，5G使無人汽車更安全；醫(yī)生更精準獲取病人的病情；VR游戲玩起來更逼真。所有這些都得益于5G傳輸速度的極大提高。由此可推知，5G使許多先進技術得到進一步優(yōu)化。故選C。 （3）考查細節(jié)理解。根據(jù)最后一段中的“ And in order to use 5G, we will have to buy new product specially designed for 5G that are currently expensive.”可知，為了使用5G，目前需要購買價格昂貴的與之配套的新產(chǎn)品。由此可知，早期使用5G的成本要高于4G。故選D。 （4）考查主旨大意?？v觀全文可知，文章從一個現(xiàn)象引出對于5G的討論，介紹了5G的優(yōu)勢和早期存在的缺陷，講述了5G將給人們生活帶來的影響。故選D。 【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，是一篇科技類閱讀，考生需要準確掌握細節(jié)信息，同時根據(jù)上下文進行邏輯推理，概括歸納，從而選出正確答案。7．閱讀理解 Regardless of how far we39。d like to believe gender(性別) equality in the workplace has e, there39。s still a yawning gap between male and female leaders in the professional world. A 2018 statistic shows that women nowadays hold just percent of CEOs positions at Samp。P 500 panies, according to Catalyst. While it39。s not a huge shock that women are somewhat underrepresented in leadership positions, what is surprising though, is the fact that females may actually be better suited to lead in almost every area, at least according to new findings from the BI Norwegian Business School. In their research，Professor yvind L. Martinsen and Professor Lars Glas surveyed (調(diào)查)2,900 managers with a special focus on personality types. The results were clear: Women scored higher than men in four of the five major leadershipcentric categories. While some people believe that men inherently make better leaders — probably because they picture a leader with a manding voice, which is more typical of men than women — this piece of research suggests that women are better at methodical management and goalsetting, openness, sociability and supportiveness, as well as ability to municate clearly. There was one area in which men scored higher than women, though, and that was on emotional stability and ability to face jobrelated pressure and stress. The results suggest that women are more sensitive to the effects of highpressure or highly emotional situations. Obviously，it39。s important to consider individual(個人的) differences. Anyone, regardless of gender, may be an inspiring leader and a petent boss. But next time you39。re hiring for a management position, you just might want to give the resumes(簡歷) from female candidates a harder look.（1）What makes us shocked much at leadership positions? A.Women are worse than men.B.Men take almost all high positions.C.
