题文

Imagine having an idea, drawing it on paper, bringing it to a store and seeing it turned into an object. This is now possible with the help of 3D printers. Such machines were once used just by universities and big companies, but now, stores with 3D printing services are appearing around the United States. Bryan Jaycox and his wife opened The Build Shop LLC in Los Angeles two years ago. The Jaycoxs offer 3D printing classes and services for anyone who is interested. “I think 3D printing is going to be huge. It’s going to have a huge influence on society as a whole.” says KiChong Tran, one of the students in a recent class. He plans to open a 3D printing business in Cambodia (柬埔寨). 3D printing services are coming into American people’s life. The UPS Store is a nationwide retailer (零售商) that provides copying and other services. The UPS Store recently put 3D printers in three of its independently-owned stores. Burke Jones owns one of the stores in San Diego. “The demand has been amazing. There has been a lot of interest from people. It’s been much more than I would have imagined.” The UPS Store plans to add 3D printers in three more stores. For $11, someone used a 3D printer to produce two small plastic parts as part of a knuckle (指节) for a hand. He works for the company which is testing finger prosthetics (假肢). He says the same–day or next-day printing services will speed up testing of parts and get them to patients faster. Staples, an American store, is selling 3D printers on its website for as low as about $1,300. As with any technology - experts expect the printing speed to increase and the price to go down. Bryan Jaycox requires $15 an hour to print an object. He also sets the price depending on the size of the object and up to $50 an hour for design and labor services. Mr Jaycox thinks that within five years, 3D printing technology could become more user friendly. But KiChong Tran says even today’s technology can make a difference in a developing country like Cambodia. “With 3D printing you can give them tools, so they are responsible more for their own development and they learn skills beyond just like learning English and becoming a tour guide or something like that. You can actually create things that give value to the world.” He says it’s not just Cambodia but anywhere where there is a 3D printer, it can turn a good idea into reality. 小题1:What can 3D printers do according to the passage? A．Come up with an idea. B．Draw on a piece of paper. C．Help users to spend less money. D．Turn an idea into a physical object. 小题2:What does the underlined part mean in this passage? A．Make users’ life better. B．Make friends with users. C．Make 3D printers easier to use. D．Use 3D printers to make money. 小题3:What can we infer from the passage? A．3D printing is becoming popular in the world. B．There is no 3D printing business in Cambodia. C．The UPS Store is the biggest 3D printing company. D．3D printing plays the most important role in daily life. 小题4:What’s the passage mainly about? A．The future of 3D printing in the world. B．The 3D printing business in Cambodia.

政治经济类阅读

考点名称：政治经济类阅读

• 政治经济类阅读：
  该类文章时代气息浓郁，语言鲜活，但熟字新义词、超纲词及专业词语多，长句、难句多。
  政治类文章大多数是同学们感性趣的内容，读起来倒有似曾相识的感觉，经济类文章读起来就像是雾里看花，文章看完，一头雾水。
  再加之这类文章的命题侧重于词义猜测、推理判断和文章主旨，同学们对这类题材是望而生畏。
  

• 政治经济类阅读注意：
  1、要做好这类阅读，平时就要注意了解国内外发生的政治经济大事，掌握一定背景知识；
  2、对这类文章的叙述特点及内容安排有一定了解，还要扩展这方面的词汇；
  3、阅读这类文章，要抓住文章的核心，即文章整体和各段主要在说什么，也要注意段落之间的逻辑关系。

  政治经济类阅读技巧：
  针对不同体裁的文章，我们要采取相应的阅读方法和技巧。政治类文章多采用记叙文形式，我们可采取“顺读法”，以便抓关键语句，领会文章主旨；而经济类文章则多采用说明文形式，我们则可以采取“逆读法”，先读试题，再从文章中查找有用信息。若遇到的确难读的材料。
  1. 寻找主干：
  根据英语中五种基本句型结构，把句子中的主语、谓语、宾语、表语等主要成分找出来，其他成分如定语、状语、补语等则易于理解。找到了句子主干，句子的意思至少明白了一半。
  2. 剔除从句：
  在一个长句中可能会出现若干个从句，在理解时，如果把各个从句剔除出来单独理解，然后把大意拼凑起来，整个长句的意思就会明白六、七分。
  3. 辨别分句：
  一个长句如果是由几个并列、转折、递进、对比关系的分句组成，句中往往有表示这些分句关系的连接词，只要能弄清楚分句和分句之间的逻辑关系，再把各层分句的意思加以连贯，整个长句的句意基本上能跃然脑中。
