纵观过去的几年，汽车行业所使用的新技术已经影响到了生活中的每一个人，例如遍布城市各个角落的滴滴、优步，而中国互联网的高速发展也为以汽车为载体打造的移动互联平台提供了新的市场机遇，我们可以好不夸张的说:我们正在由汽车数字化转向汽车智能化 。数字化是实现智能化、网联化、“工业4.0”等未来愿景的技术性基础，现在虽然没有企业能够全部实现数字化，目前负责研发、生产、销售的部门还是各自分开的独立系统，还属于各自为政的一个阶段，如何能够建立一个共同的、基于数字化的平台，然后在既有的基础上开展诸如机器学习、人工智能等，才能够进入到数字化的下一阶段才是我们应该思考的事情 。
雅思英语阅读“段落标题配对题”该怎么做？

雅思阅读考试中，“段落标题配对题”（Matching headings）由于选项数目大大多于文章中段落的数目，且需要花费大量时间理解段落，无疑是很多人的噩梦 。段落标题是段落的大意、中心思想或主旨 。因此，要正确匹配段落标题就必须先理解段落的大意 。但现实是，雅思考试时我们没有那么多时间去仔细阅读 。如果给大家1个小时做一篇文章，我相信大部分同学还是能够准确做对的 。
Luckily，根据英文写作规范，英文段落是存在标准结构的，具体如下：根据上述段落结构，一个标准的英文段落，第一句话为段落的Topic Sentence，也就是中心句 。最后一句是结尾句，也是概括本段的中心大意，中间部分则是支撑观点和细节 。而“段落标题配对题”正好需要我们掌握段落的大意 。由此可见，我们是可以通过查看段落的Topic Sentence来直接答题的 。
段落的Topic Sentence在段落中一般会出现在以下5个位置：1.段首第一句话一个段落如果存在中心句，绝大部分情况会是在第一句话 。Placing the topic sentence at the beginning of a paragraph offers a number of advantages (中心句). To begin with, it can help the writer keep an eye on paragraph unity by providing a guide for selecting details for the rest of the paragraph. For readers, placement at the beginning establishes the initial context, giving them the foundation they need to understand the details which follow. This is especially true if the writer not only introduces the main point in the topic sentence, but also forecasts the paragraph’s organization with phrases like “a number of advantages.”2.段中第二句话在这种情况下，第一句话往往是引出本段落要讨论的话题 。
在下面的段落中，第一句话引出“topic sentence”这一话题，第二句话为中心句 。This is not the only place the topic sentence can go, however. Many times the topic of a paragraph may be introduced after a transitional sentence (中心句). The transitional sentence guides the reader through a shift in thought, pointing back to the previous idea and forward to a new one. That new idea becomes the topic sentence of the new paragraph, and is followed, as before, by supporting and clarifying details.3.段尾最后一句话在这种情况下，段落前面往往是一系列的例子或事实，最后用一句话总结前面的例子或事实 。
What if you decide a paragraph should be developed in indirect order? It may be that the point you’re making is very controversial, so much so that your readers might disagree with you. Or you may feel that leading the readers through a series of supporting details might make comprehension of the main idea easier, letting them “warm up” before learning your message. Sometimes building up slowly to a main idea can be used as a dramatic tool as well, keeping readers guessing until the last instant. In these situations, it may be best to place the topic sentence at the end of the paragraph (中心句).4.段首第一句和段尾最后一句话这种情况下，往往段落内容较多和复杂 。
