Unit 4 SharingⅠ.阅读理解APatients in the early stages of Alzheimer's disease often struggle to remember recently learned information, meaning they forget things like important appointments or where they left their keys. But it seems that these memories are not lost. They are still filed away in the brain somewhere; they just can't be easily accessed.Now, researchers at MIT have developed a means of getting back me mories in mice suffering from Alzheimer's. The method relies on a technique that uses light to control genetically modified neurons (转基因神经元). Currently it is too early to be used in human trials as it involves inserting light emitting(发光) equipment into the subjects' brains, but the same principles still apply, the researchers said.“The important point is that this is evidence of the concept. That is, even if a memory seems to be gone, it is still there. It's a matter of how to get i t back，”said the senior researcher Susumu Tonegawa.The team took two groups of mice, one genetically engineered to develop Alzheimer's and one healthy. They then placed them into a room and gave them a mild electric shock.All of the mice showed fear when put back an hour later. When placed in the room a third time several days later, the Alzheimer's mice acted normally. They had forgotten the shock.The researchers were then able to bring back the memory of the shock by activating(激活) the cells in which the memories were stored. Even when the mice were put into an unfamiliar room, they showed fear when the cells associated with the shock were activated.“Shortterm memories seem to be normal in order of hours.But for longterm memories, these earlyAlzheimer's mice seem to be damaged，”said the lead researcher Dheeraj Roy.“Directly activating the cell s that we believe are holding the memory helps them get it back. This suggests that it is indeed an access problem to the information, not that they are unable to learn or store this memory.”[语篇解读] 本文主要介绍了利用光控制转基因神经元使早老性痴呆病患者恢复记忆的技术。
1．What can we learn about the researchers at MIT?A．They are the pioneers of brain research.B．They have used the method in human trials.C．They can cure Alzheimer's using the new method.D．They can get back memories in mice with Alzheimer's.解析：细节理解题。
根据第二段的第一句“Now，researchers at MIT have developed a means of getting back memories in mice suffering from Alzheimer's.”可知，他们能够使患有早老性痴呆病的老鼠恢复记忆。
答案：D2．Why did the Alzheimer's mice behave normally the third time?A．They failed to remember the electric shock.B．They were accustomed to the situation.C．They managed to overcome the fear.D．They activated the association automatically.解析：细节理解题。
根据第四段的“the Alzheimer's mice acted normally.They had forgotten the shock.”可知，这些老鼠忘记了受到的电击。
答案：A3．For longterm memories, the earlyAlzheimer's mic e .A．can transform their brain cellsB．can't learn new tricks wellC．can easily get back their memoriesD．can't access the information stored解析：推理判断题。
根据最后一段的“But for longterm memories，these earlyAlzheimer's mice seem to be damaged”和“Directly activating...this memory”可知，对于长期记忆来说，这些处于早老性痴呆病早期的老鼠因为(脑细胞)已经被损害，不能获得这种已经储存的信息。
答案：D4．The main purpose of the text is to .A．introduce a method of a researchB．report the latest discovery about a diseaseC．give advice on how to improve memoriesD．explain how a brain stores information解析：作者意图题。
通读全文可知，本文的主要目的是报道关于早老性痴呆病的最新发现。
答案：BBIf you followed the 2016 Olympic Games, you may have noticed that several athletes, including US swimmer Michael Phelps, had circular bruises on their bodies. These bruises were the result of “cupping (拔火罐) therapy”， a traditional Chinese medicinal practice that has been around for more than 2,000 years.Many athletes say that they have benefited from the therapy. Phelps used the therapy in the fall of 2014 and has used it about twice a week since, reported ABC News. Another US swimmer, Dana Vollmer, also believes that “it really helps with blood flow”．However, some have said that the supposed health effects result from people's feeling that the treatment works, rather than any physical effect of the treatment.To figure out cupping therapy has any physical effect, last year researchers from Germany carried out a test in which a false treatment was provided.In the study, the same type of cups was used in the real treatment and the false treatment. But in the false treatment，the cups had a hole at the top so that they couldn't create the proper suction (吸力)．The tested patients, who suffered from a disorder that caused a lot of pain, were told that they would receive either t raditional cupping or “soft cupping”. But they were not informed that the socalled “soft cupping” was a false treatment.It turned out that most patients correctly guessed which kind of cupping they had received. In both groups, patients also experienced about the same reductions in pain. “The results suggest the effects of cupping therapy might come from factors that are not necessarily part of the treatment itself，” the researchers told the Live Science website.The question of whether cupping therapy w orks still needs to be answered.“But because the treatment is relatively safe and it could be helpful for some people, the therapy can be used as part of a comprehensive treatment program involving other exercises, nutritional choices and lifestyle changing，”Dr Brent Bauer, director of the US Complementary and Integrative Medicine Program at Mayo Clinic, told Live Science.[语篇解读] 本文主要介绍了中国传统医疗方式拔火罐的实际疗效问题。

2020版高考英语(人教·全国版)一轮复习学案语法第一部分第四讲词性转换(构词法)含解析
第四讲词性转换(构词法)英语构词法主要有三种：合成、转化和派生。
合成是指将两个意思不同的单词结合成一个新词；转化是指一个单词的词形不变而由一种词性转化为另一种词性；派生是指通过给一个单词加前缀或后缀变成另一个词。
前缀一般改变词义而不改变词性，后缀一般改变词性而不改变词义。
将构词法置于此处讲解，一是对前面基础词法的汇总，二是为攻克后面的重难动词做铺垫。

2．(2018·6月浙江高考)Researchers have found that there is a direct link between the increase in food eaten outside the home and the rise in ________(weigh) problems.解析：weight根据语境可知，此处表示体重方面的问题，故此处填名词作定语。
3．(2017·全国卷Ⅲ)She is determined to carry on with her ________ (educate)．解析：education前面有形容词性物主代词her，此处应该使用动词educate的名词形式education作宾语。
4．(2016·全国卷Ⅰ)Chengdu has dozens of new millionaires, Asia's biggest building, and fancy new hotels. But for tourists like me, pandas are its top ________ (attract)．解析：attraction此处作表语且前面由its top修饰，应该用attract的名词形式attraction，意为“吸引人之物，诱惑物”。
