　　一、阅读理解。
　　(2018•河南洛阳高三第一次统考)
　　All over the world mothers and fathers teach their children manners.Other children may have manners that are not lirs.There are all kinds of manners.
　　Many years ago，children who had good manners were seen and not heard.They ite quiet if grown-ups were talking. Today, well-mannered children have more freedom.
　　Sometimes good manners in one place are bad manners in other places. Suppose you are a visitor in the land of Mongolia. Some friends as to eat with them. What  kind of manners do they want you to have? They want you to give a loud “burp(打嗝)” after you finish eating. Burping would show that you lir food. In some countries, if you give a loud burp, you are told to say “Excuse me, please.” In many places people like to eat together. But in some parts of Polynesia it is bad manners to be seen eating at all. People show good manners by turning their backs on others while they eat. What are manners like in an East African town? The people try not to see you. They are being polite. You may see a friend. He may not see you at all. If you are polite, you will sit down beside him. You will wait until he finishes what he is doing.Then he will tal.Suppose you visit a friend in Arabia.You should walk behind the other tents until you come to his tent.If you pass in front of the other tents，you will be asked into each one.The people will as to eat with them.And it is bad manners if you say no.

　　Unit 2 Robots
　　一、阅读理解。
　　Vitamin B could help lessen the effects of the most dangerous type of air pollution, according to a new study published recently. In the first study of its kind, a team of international researchers looked at the damage caused by one of the pollutants that have the most severe impact on health: PM2.5.
　　Particulate matter, or PM, is a type of air pollutant consisting of small particles of different sizes. PM2.5 has a diameter of fewer than 2.5 micrometers, about 30 times smaller than a human hair. These particles are so small that they can go into our respiratory system(呼吸系统), resulting in lung and systemic inflammation(炎症) and stress.
　　The team found that something as simple as a daily vitamin B supplement could potentially reduce the impact of the tiny particles on the human body, although they stressed that the research was in its early stages and the sample size was small.
　　For this study, 10 volunteers were initially exposed to clean air and given a placebo(安慰剂) to check their responses. The group then took another placebo for four weeks before being exposed to heavily polluted air from downtown Toronto, where an estimated 1，000 cars pass every hour. The bad air was delivered to the volunteers through an “oxygen-type” face mask. The experiment was then repeated, with each volunteer taking a B vitamin supplement daily made up of 2.5 mg of folic acid, 50 mg of vitamin B6, and 1 mg of vitamin B12. B6 can be found in liver, chicken and nuts, and B12 in fish, meat, eggs, milk and some cereals.
　　The researchers found that four weeks of B vitamin supplements reduced the damage of PM2.5 exposure by 28%－76%. The results highlight how prevention at an individual level could be used to fight the harmful effects of PM2.5.
　　【解题导语】　本文是一篇说明文。吸入人体内的PM2.5(细颗粒物)会导致疾病。不过，研究发现维生素B在一定程度上能降低PM2.5的危害。
　　1．Why is PM2.5 harmful to our health?
　　A．It pollutes and poisons the air.
　　B．It is too much to be got rid of.
　　C．It carries viruses and diseases.
　　D．It is easily breathed in and damages our body.
　　D　解析：细节理解题。根据第二段中的“These particles are so small...inflammation(炎症)and stress.”可知，PM2.5(细颗粒物)很小，能进入我们的呼吸系统，导致肺部和全身炎症。
　　2．What can we infer from Paragraph 3?
　　A．The process of the research was not scientific.
　　B．This kind of research has been done many times.
　　C．Further studies are needed to confirm their findings.
　　D．Vitamin B is hard to obtain in people’s daily life.
　　C　解析：推理判断题。根据第三段中的“although they stressed that the research was in its early stages and the sample size was small.”可知，该项研究处于初级阶段且样本规模小，因此还需要更多的研究来证明研究团队的发现。
　　3．What is the text mainly about?
　　A．International researchers have a new finding.
　　B．Vitamin B could reduce the damage of PM2.5.
　　C．Particulate matter does great harm to our health.
　　D．Emission control and regulation are badly needed.
　　B　解析：主旨大意题。文章第一段和第二段谈到PM2.5的定义以及PM2.5的危害；第三到五段告诉我们维生素B能降低PM2.5的危害。所以B项最能概括文章主旨。
　　4．The new study was probably published ___________    ．
　　A．in a science journal
　　B．on a government website
　　Unit 3 Under the sea
　　一、阅读理解。
　　Wouldn’t it be wonderful to travel to a foreign country without having to worry about the headache of communicating in a different language?
　　In a recent article from The Wall Street Journal, technology policy expert Alec Ross argued that，within a decade or so, we’ll be able to communicate with one another via small earpieces with  built-in  microphones.   That’s  because  technological progress is extremely rapid.It’s only a matter of time. Indeed, some parents are so convinced that this technology is imminent that they’re wondering if their kids should even learn a second language.
　　It’s true that an increase in the quantity and accuracy of the data loaded into computers will make them cleverer at translating “No es bueno dormir mucho” as “It’s not good to sleep too much”. Replacing a word with its equivalent(对应词) in the target language is actually the “easy part” of a translator’s job.But even this seems to be a discouraging task for computers.
　　It’s so difficult for computers because translation doesn’t —or shouldn’t—involve simply translating words, sentences or paragraphs. Rather, it’s about translating meaning.  And in order to infer meaning from a specific expression, humans have to interpret a mass of information at the same time.
　　Thint all the related clues that go into understanding an expression: volume, gesture, situation, and even your culture. All are likely to convey as much meaning as the words you use.
　　Therefore ，we should be very skeptical of a machine that is unable to interpret the world around us. If people from different cultures can offend each other without realizing it, how can we expect a machine to do better? Unless engineers actually find a way to breathe a soul into a computer, undoubtedly when it comes to conveying and interpreting meaning using a natural language, a machine will never fully tar place.
　　【解题导语】　技术专家说随着技术的进步，即时翻译机器将在大约十年内出现在市场上。但是，由于翻译包括很多方面，因此电脑翻译不会精确，也不会完全取代人类的翻译。
　　1．What does the underlined word “imminent” in Paragraph 2 probably mean?
　　A．Ready.　　　　　　 B．Approaching.
　　C．Helpful. D．Advanced.
　　B　解析：词义猜测题。根据画线词所在句的前一句并结合第二段的第一句可知，这种产品在大约十年内会在市场上出现，再结合画线词后的“that they’re wondering if their kids should even learn a second language”可以判断，这种产品即将出现，家长们在考虑他们的孩子是否要学习一门外语。据此可知，画线词意为“即将发生的；临近的”，故B项正确。
　　2．Why is it hard for computers to replace a word with its equivalent?
　　A．Their data is not adequate enough.
　　B．The real meaning of words can vary.
　　C．Their accuracy needs big improvement.
　　D．A soul hasn’t been breathed in them.
　　B　解析：细节理解题。根据第四段的“It’s so difficult for computers because translation doesn’t—or shouldn’t ... paragraphs.”并结合第五段的内容可知，由于一个表达的意思可能有很多，所以电脑难以用某个对应词去代替一个词，故B项正确。
　　3．What view does the author hold about translation?
　　A．Proper translation can be tough for humans.
　　B．Slight distinctions matter little in translation.
　　C．Some machines will interpret our world properly.
