【正文】 young is better than the old.C. The researchers used existing data for 1, 062 people between the ages of 55 and 90 that had been recorded over a 12year period. The data included brain scans, which the researchers used to look for visual signs of reduced glucose uptake（葡萄糖吸收）.It is an objective marker of the sort of reduced brain function that goes along with expected, glucose uptake was reduced in those with AD. What the researchers also discovered was that glucose uptake was reduced in those with mild cognitive damage who also showed evidence of reduced illness awareness. Finally, the researchers found that those who had reduced illness awareness were more likely to develop AD than those without.（1）What can be implied from paragraph 1？ A.

A.To prove sharing food increases petition.C.A meal taken in a family atmosphere.（2）For what purpose did the researchers carry out the present experiments? A.A meal consumed by oneself.B.A meal taken at home. The researchers measured cooperation by noting the number of rounds it took to reach an agreement, and found that those who shared food resolved the strike significantly faster（in 8. 7rounds）than those who did not（ rounds）. A similar experiment was conducted with 104participants and Goldfish crackers（餅干）, this time negotiating an airline39。 For the first test they recruited 100 pairs of participants from a local cafe, none of whom knew each other. The participants were seated at a table and fed tortilla chips with salsa. Half the pairs were given their own basket of 20 grams of chips and a bowl of 25 grams of salsa, and half were given 40 grams of chips and 50 grams of salsa to share. As a cover for the experiment, all participants were told this snack was to be consumed before the game began. Having conducted previous research in 2017 revealing that eating similar foods led to people feeling emotionally closer to one another, Dr Woolley and Dr Fishbach wondered whether the way in which food was served also had a psychological effect. They theorized that, on the one hand, sharing food with other people might indicate food scarcity（短缺）and increase a feeling of petition. However, they also reasoned that it could instead lead people to bee more aware of others39。4．犇犇閱讀理解 ”故選A。與此同時，仍有很多工作要做，包括各種試驗，以確保收音機能很好地配合硬件和基礎(chǔ)設(shè)施建設(shè)，這樣5G就不會只集中在大城市。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。根據(jù)最后一段中的“But don39。故選D。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.”這一點值得注意，因為據(jù)報道，蘋果(Apple)等公司正在開發(fā)增強現(xiàn)實眼鏡，以幫助——甚至取代——智能手機。故選C。 （2）考查詞義猜測?？芍?，作者在第一段想強調(diào)“5G光速快。根據(jù)第一段中的“Slowly but surely, we39。The 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，介紹了我們離5G世界越來越近了。Why 5G isn39。How to fully expand 5G coverage.B.Apple pany is developing AR glasses worldwideD.t e without AR glassesB.Explanation.（3）We can infer from the text that ________.
