The development of the London underground railway
In the first half of the 1800s, London’s population grew at an astonishing rate, and the central area became increasingly congested. In addition, the expansion of the overground railway network resulted in more and more passengers arriving in the capital. However, in 1846, a Royal Commission decided that the railways should not be allowed to enter the City, the capital’s historic and business centre. The result was that the overground railway stations formed a ring around the City. The area within consisted of poorly built, overcrowded slums and the streets were full of horse-drawn traffic. Crossing the City became a nightmare. It could take an hour and a half to travel 8 km by horse-drawn carriage or bus. Numerous schemes were proposed to resolve these problems, but few succeeded.
剑桥雅思 17 Test 1 的阅读 Passage 1 讲伦敦地铁的早期发展，标题是 The development of the London underground railway。试读页只放文章首段，后面还有判断题和匹配题，完整内容需要进入练习页。
这篇的类型
Passage 1 通常是三篇里最容易的，题材偏说明性，结构清楚：时间线、原因、影响，一段一个层次。伦敦地铁这篇按发展过程推进，读的时候先找时间词和转折词，把段落之间的关系串起来，而不是逐句翻译。
题目里除了填空题，还有一组匹配题。匹配题的分值不低，答案位置分散，先读题干、记下关键词，再回文章扫读，比从头读到尾省时间。
首段怎么用
首段的信息量有限，不适合拿来练整套阅读。它适合做一件事：判断这篇文章的语感和难度，决定要不要把它安排在完整套题里练。
读首段时做两件事：标出主题词，看后面题目会不会围绕它出；数一下不认识但影响理解的词，超过三四个，说明这篇需要先补词汇再做题。
完整练习怎么排
阅读 60 分钟，三篇文章的合理分配是 15 到 20 分钟一篇，留 5 到 10 分钟检查。Passage 1 尽量在 15 分钟内完成，把时间让给 Passage 2 和 Passage 3。
做题顺序按文章顺序走，同一篇里的题也按顺序做。先做填空题和判断题，再做匹配题；匹配题放到最后，避免在一道题上卡太久。
匹配题放到最后
Passage 1 的匹配题要求把段落信息和题目对应，选项多、定位散。如果先做匹配题，容易在文章里来回跳，把时间耗光。先做填空和判断，对文章结构有印象后再做匹配，定位会快很多。
做完一篇立刻记下用时，三篇加起来超过 60 分钟，下一篇就要调整。阅读的分数提升通常来自“少错同一类题”，而不是“多读几篇”；每套只挑一类错题复盘，下一套专门盯它。
首段试读只是这套题的开头。想完整练这一套，可以进入阅读练习；想先试听力，转到听力试读页。
首段的专有名词多，地名、线路名先做标记；正式做题时按专有名词回原文定位，比通读一遍再找更快。
试读之后怎么练
先浏览题目要求，再回到文章定位相关信息；完成后记录误读的句子和定位耗时。试读不能提交整卷；登录后可进入完整练习并保存作答。
