Each passage is followed by four comprehension questions. Read the passage and answer the questions. Then mark your answer on the Answer Sheet. Passage One Questions 1 to 5 are based on the following passage: Animals react to the changing seasons with changes in mood and behavior and human beings are no exception. Most people find they eat and sleep slightly more in winter and dislike the dark mornings and short days. For some, however, symptoms (症状) are severe enough to damage their lives and to cause considerable stress. These people are suffering from SAD. The symptoms tend to start from around September each year lasting until April, but are at their worst in the darkest months. The standard figure says that around 2% of people in Northern Europe suffer badly, with many more (10%) putting up with milder symptoms. Across the world the incidence (发生率) increases with distance from the equator (赤道), except where there is snow on the ground, when it becomes less common. More women than men are found having SAD. Children and young people can also suffer from it. The problem stems from the lack of bright light in winter. Researchers have proved that bright light makes a difference to the brain chemistry, although the exact means by which sufferers are affected is not yet known. As the cause is lack of bright light, the treatment is to be in bright light every day by using a lightbox or a similar bright treatment. (Going to a brightly-lit climate, whether skiing or somewhere hot, is indeed a cure). The preferred level

2017年四川理工学院专升本专业目录计划

一报考条件:根据文件规定,四川理工学院专升本,本次选拔对象,应符合以下条件:1.在校期间政治思想表现优秀,遵守校纪校规,文明礼貌,未受到任何处分。2.学历要求:具有本科专业对口,无重考,无重修记录,身心健康。3.以综合考试成绩为录取依据,首先按各专业实考人数划定分数资格线,再按成绩从高到低择优录取。4.综合考试成绩将在录取前公示7天,录取过程中,如果有排名在录取名额内的考生自愿放弃,在名额外的学生按顺序递补。5.我校采取笔试、口试或两者相兼的方式进行,以进一步考察学生的专业基础、综合分析能力、解决实际问题的能力。具体比例由学校根据学科专业特点安排。 二报考事项:历年真题QQ在线咨询:363.916.816张老师,各相关专业成立考试小组,确定工作中的相关原则政策和办法研究重大事项;负责本学院考试工作的组织宣传事项和实施工作;完成报考成绩统计及综合排名汇总材料并上报填表。1.各学院要先完成报考专业的成绩综合排名,根据名单确定考生的具体范围。 2.符合上述条件的参加综合考试,按照报考专业并提交书面申请材料审核。 3.工作领导小组审核汇总名单后,将公示7天,期满后不再进行提示。 4.各相关专业按照考试科目的顺序依次进行。 5.考试成绩以书面通知形式发到学生本人。 三考试流程:1.参加初试并获得复试资格的考生,应在复试前填写相关表格,按规定时间提供自身研究潜能的材料,攻读大学阶段的研究计划、科研成果等。2.报考考生的资格审查由领导小组进行审查,对考生料进行审阅符合报考条件的统计填表。3.我校采取笔试、口试或两者相兼的方式进行差额复试,以进一步安排加强进行考察学生的专业基础、综合分析能力、解决实际问题的能力和各种应用能力等。具体比例由学校根据本学科、专业特点及生源状况安排。 四复习方略:1注重课本很多考生会安排各种各样的资料,其实关键要能保证你进行的系统性。每个要点段落安排以真题为主,时间布局以精读的方式对重点章节相关要点,对课本有一个纲领性的认识。对课后题必须要掌握,很多知识点题都出自课后。系统的了解都要为基础一定要做到对书的大体框架有全面的把握,把整个原理的前后概念贯穿起来。2.在复习充分的情况下做完后对照答案进行对比,看看自己的差距到底在哪个环节。接下来才是最重要的,要根据专业课的真题都会出的科题型,总结其考察重点是什么是哪一章节。在熟悉这些之后呢,特别邀请加强对试题都整理出来行理解背诵。根据科目的先后顺序,因为最近规划前几年出现的题目会出现,根据专业不同特点分析对照问题的深度和广度,结合自己的知识结构知识存量,正确的安排答题技巧针对有限的知识来最好地回答。专业课的难度绝不亚于英语,对掌握的侧重范围思路结合考核要求内容的分析能力,根据你的水平处于中等你自己也会知道,在英语上拉分的几率太小英语能过线就可以。外语的要求总体相对较小,不需要投入过多的精力,只需按照老师的建议进行就好。而恰恰专业课往往会成为各位考生的短板。根据自身掌握情况安排时间,给众多考生以正确的引导。 五答题技巧:1辨析题的中心话题多是考试大纲中的重点、难点或容易发生要求的内容,其观点分析进行,考生解答时往往容易。这类试题有利于提高考生在学习中的把握问题不全面现象,突出了对理解能力分析能力的考查,但同时也增加了试题的难度。考生答题时要先明确认真分析,然后再进行书写。由于题目本身难度较大,因此安排时间分析时要先围绕前半句解析,然后围绕技巧总结最后得出结论。简答题主要考查考生对基础知识和基本理论的攻科掌握。考生答题时也要适当展开,最好按照平时答论述题的方式回答,并且注意条目清晰、要点准确。另外,围绕要点所作的解析相对严谨和条理介绍确切。2.论述题的考核比较灵活,不限于书本知识结构。考生答题时不仅要思路明晰,而且要全面展开,先把理论阐明,再联系实际作相应陈述。若给出一定的文本材料,考生要注意分析文本,尽量顺应给定文本的表达方式和风格,并适当引用文本中的语言作答。考生解答分析论述题要能体现自己扎实的理论修养和相对独特的观点,这一阶段要查漏补缺,对大纲知识点进行地毯式温故和学习。要注重对整体知识结构的性质以及对至的运用,把考核和答题结合起来,提高自己分析问题和解决问题的能力,要科学的模考实战训练,做到心中有数。3已经掌握教案重点和难点知识,但是知识点很多这一阶段考生要在准备时间的基础上回归试题,依据大纲

The magic beans will ward off skin cancer and Alzheimer’s(老年痴呆症), reduce heart failure and diabetes(糖尿病) risks, heighten focus, and maybe even protect liver health. Oh, and decrease suicide risk, according to the newest study that validates our coffee addictions. According to a study performed by the Harvard School of Public Health and published this month in The World Journal of Biological Psychiatry, people who drink two to four cups of java each day are less likely to commit suicide than those who don’t drink coffee, drink decaf, or drink fewer than two cups each day. The study followed over 200,000 people for at least 16 years. And it’s not just a weak link: the researchers found that the suicide risk was cut by around 50 percent for coffee addicts. This isn’t the first time that researchers have discovered that coffee and smiles might go hand-in-hand. A 2011 study found that women who drink coffee cut their risk of depression by 15 percent compared to those who don’t. Michel Lucas, the head researcher of the most recent study, told The Huffington Post that coffee addicts can thank caffeine for the good news. The drug may actually act like a mild anti-depressant by tweaking levels of happy hormones . Of course, there’s plenty of research out there that doesn’t look so kindly upon coffee drinkers.

2017年江苏专转本考试英语试题

Part I Reading Comprehension (20×2’=40’) Directions: There are 4 passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are 4 choices marked A, B, C, and D. You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center. Passage One Questions 1 to 5 are based on the following passage. We use both words and gestures to express our feelings, but the problem is that these words and gestures can be understood in different ways. It is true that a smile means the same thing in any language. So does laughter or crying. There are also a number of striking similarities in the way different animals show the same feelings. Dogs, tigers and humans, for example, often show their teeth when they are angry. This is probably because they are born with those behavior patterns. Fear is another emotion that is shown in much the same way all over the world. In Chinese and English literature, a ph rase like “he went pale and began to tremble” suggests that the man is either very afraid or deeply shocked. However, “he opened his eyes wide” is used to suggest anger in Chinese whereas in English it means surprise. In Chinese surprise can be described i n a phrase like “they stretched out their tongues”. Sticking out your tongue in English is an insulting gesture or expresses strong dislike. Even in the same culture, people differ in the ability to understand and express feelings Experiments in America have shown that women are usually better than men at recognizing fear, anger love and happiness on people’s faces. Other studies show that older people usually find it easier to recognize or understand body language than younger people do. 1. According to the passage, _____________. A. we can hardly understand what people’s gestures mean B. words and gestures may have different meanings in different cultures C. words can be better understand by older people D. gestures can be better understand by most of the people while words cannot 2. People’s facial expressions may be misunderst ood because ___________. A. people of different ages may have different understandings B. people have different cultures C. people of different sexes may understand a gesture differently D. people of different countries speak different languages 3. Even in the same culture, people ___________. A. have different abilities to understand and express feelings B. have exactly the same understanding of something C. never fail to understand each other D. are equally intelligent 4. From this passage, we can conclude ___________. A. words are used as frequently as gestures B. words are often found difficult to understand C. words and gestures are both used in expressing feelings D. gestures are more efficiently used than words 5. The best title for this passage be___________. A. Words and Feelings B. Words, Gestures and Feelings C. Gestures and Feelings D. Culture and Understanding Passage Two Questions 6 to 10 are based on the following passage. The English policeman has several nicknames but the most frequently used are “copper” and “bobby”. The first name comes fro m the verb “to cop” (which is also slang), meaning “to take”or “to capture”, and the second from the first name of Sir Robert Peel, a 19th century politician, who was the founder of the police force as we know it today. An early nickname for the poli ceman was “peeler”, but this one has died out. Whatever we may call them, the general opinion of the police seems to be a favorable one, except, of course, among the criminal part of the community where the police are given more derogatory nicknames which originated in America, such as “fuzz” or “pig”. Visitors to England seem to be very impressed by the English police. It has, in fact, because standing joke that the visitor to Britain, when asked for his views of the country, will always say, at some point or other, “I think your policemen are wonderful”. Well, the British bobby not always is wonderful but he is usually a very friendly and helpful sort of character. A music-hall song of some years ago was called “If You Want To Know The Time, Ask A Policema n”. Nowadays, most people own watches but they still seem to find plenty of other questions to ask the policeman. In London, the policeman spend so much of their time directing visitors about the city that one wonders how they ever find time to do anything else. Two things are immediately noticeable to the stranger when he sees an English policeman for the first time. The first is that does not carry a pistol and the second is that he wears a very distinctive type of headgear, the policeman’s helmet. His he lmet, together with his height, enables an English policeman to be time it is suggested that the policeman should be given a pistol and than his helmet should be taken from him, but both suggestions are resisted by the majority of the public and the police themselves. 6. Nowadays British people call the policeman ___________. A. pig B. peeler C. bobby D. fuzz 7. Which of following statements is TRUE? A. There are fewer criminals in America than in Britain. B. The English police usually leave a deep impression on visitors. C. The English bobby is friendly but not helpful. D. The English police enjoy having pistols. 8.
