职称英语核心词汇汇总

职称英语考试备考技巧一、词汇：需要考生在最后阶段练习查字典，建议一天练习查60对，而且一个词汇题要反、正查，同时也要进行职称考试中常考词汇的记忆，这样可以在考试时提高速度，节省时间。词汇题一般情况下仅凭字典一般也能做对，因此考生对自己不认识、不熟悉或没有绝对把握的题一定要通过字典来确认，从而确保词汇题100%的正确率。特别提醒考生，考试时要带上一本带有同义词的词典。且词典不能含有职称、考试等字样，更不能带电子词典。二、阅读判断：答题时需掌握一条原则，就是在文章中有明确提出的才能确定为对。题目中若出现must、only、all、always等时，答案一般不会是对的。除上面的原则外，一般根据下列原则和规律也可以确定正确答案。选择A、B或C的三种情况：选A的情况：如果某题干与原文信息完全一致或基本一致选B的情况：如果某题干与原文信息完全相反选C的情况：如果某题干部分或局部信息在原文中未提到三、概括大意和完成句子：概括大意要先看选项，寻找关键词，确定所考段落。完成句子则要根据所给的短句进行选择，比较好的方法是找同类动词。同时读每段话时，要抓住该段话的主题句和核心词汇，正确答案常常是主题句的改写。读每段话时，并不是该段话全要仔细阅读。这样，既浪费时间，也不容易抓住重点。应该抓住该段话的主题句。四、阅读理解：首先要重点掌握教材上的阅读理解的重点文章的背诵，来抓住出自教材上的分数，这是顺利通过考试很关键的一步。

同时充分利用老师在课上讲的解题技巧，如大标题做题法、红花绿叶原则、顺序出题原则、关键词回归定位法通过做模拟试题来进行解题技巧的演练和应用。在做题时要注意：搞清主旨题、细节题、推理题、逻辑关系题、观点态度题。注意标题、首尾段、首尾句、逻辑关系处、细节处等出题点；在阅读时见到日期、数量等要先做好标记，这样有重点有理有节的解题，才有可能取得满意的成绩。五、补全短文：要先看标题定文体，再看选项，观察选项时应注意抓主干，猜大意，弄清选项大意是表示定义、因果、例子还是措施；不要放过代词、专用名字、连接词、数字等特征词；然后回头再去看课文，明确1-5的位置。解每道题时只需要阅读该题所在段落，不需要阅读其他段落。往往通过阅读该题目的前后句就能够确定答案，在考试时，应该注意利用以下前后句子存在的关系来做题： (1)利用转折关系 (2)利用归纳总结关系 (3)利用总分关系 (4)利用并列关系六、完形填空： (1)掌握教材上的文章内容，尤其是2013年新增文章。把这些文章在考前一个月内，争取背到“滚瓜烂熟”，这样，就算考试时怎样变化都可以应付。 (2)语法知识的总结和固定搭配、词组的记忆。这样在做题时，阅读整篇文章，考生才能从头判断每个空所缺的词的语言形式，如词类、时态、语态，并判断该词应具有的符合文章上下文的词义，最后从给出的四个选项中，选出在语法与词义上均与原文相符合的一个。除掌握以上解题技巧外，考生最好配合在模拟真实的考试时间进行模拟试题的演练，这样不但可以直接掌握复习效果，还可以迅速找到自己的薄弱环节，通过单项训练，逐一提高成绩。最后，提醒考生，在抓紧时间复习的同时要放松心情，以轻松的心态迎接考试。预祝顺利通过考试！全国职称英语考试必过秘籍（免背单词+免读全文版） 1、试题概况及答题顺序 1.1、必杀技：见下表中“答题顺序”：

2020年职称英语理工A概括大意真题及答案

2020年职称英语理工A概括大意真题及答案 Geothermal(地热)Energy 1.Since heat naturally moves from hotter regions to cooler ones, the heat from the earth's center flows outwards towards the surface. In this way, it transfers to the next layer of rock. If the temperature is high enough, some of this rock melts and forms magma(岩浆). The magma ascends in its turn towards the earth's surface. It often remains well below the earth's surface, creating vast areas of hot rock. In such regions, there are deep cracks, which allow rainwater to descend underground. Some of the heated rainwater travels back up to the earth's surface where it will appear as a hot spring. However, if this ascending hot water reaches a layer of impermeable(不可渗透的)rock, it remains trapped, forming a geothermal reservoir. If geothermal reservoirs are close enough to the surface, they can be reached by drilling wells. Hot water and steam shoot up the wells naturally, and can be used to produce electricity in geothermal power plants. 2.A few geothermal power plants depend on dry-stem reservoirs which produce steam but little or no water. In these cases, the steam is piped up directly to provide the power to spin a turbine generator. The first geothermal power plant, constructed at Lardarello in Italy, was of this type, and is still producing electricity today. 3.Most currently operating geothermal power plants are either "flash" steam plants or binary(双重的)plants. Flash plants produce mainly hot water ranging in temperature from 300° to 700°Fahrenheit. This water is passed through one or

Is it art or is it just vandalism (野蛮行为)? Well, it's still a crime, but graffiti (涂鸦) has changed since the days of spraying your name on a wall to mark your territory. Street art has become much more sophisticated since a 17-year-old called Demetrius started spraying his "tag" , TAKI 183, all over the New York underground in 1971, and hip - hop culture was born. Hip-hop is a mixture of art, music and dancing, poetry, language and fashion. It came from young inner-city people who fell left out by their richer classmates and who were desperate to express themselves in any way they could. An experiment to control the spread of graffiti in Rochdale, Creater Manchester, has been sosuccessful that plans have been made by local street artists for an international convention in June. "We're planning to get people together from different countries like France and Cermany for a week, " says Liam, one of the organizers. The scheme started in 2000, and has attracted people of all age groups and both sexes. " We all share a commen interest and get on really well with each other. " The first site to be chosen was a subway. " Before we began, people were afraid to use the subway. We had it cleaned up and now, with all the artists hanging out down there, people are using it again. People can relate to graffiti much more now. " By providing places to display their talents legally, there has been a fall in the amount of "tagging" on people's private property. Street artists Temper developed his drawing skills at a young age. In art classes at school he was really frustrated because the Art teacher didn't spend time with him. They thought he was already very good at art and so spend more time with other students. So, at 12 years old, Temper started painting with all these guys he'd hooked up with who were about 22 years old. He looked
