备考提醒
要做好这类阅读理解题，先要掌握这类文章的特点和结构， 真正读懂并理解它。 其次，工夫在课外，平时一定要多读科技幻想类文章 比如：太空与海洋、创造与发明、计算机发展、人类未来、 动物世界等。特别是从网上搜寻一些取材原版、内容时新、 语言鲜活的科技幻想类材料阅读。这样长期坚持，既可以 增长知识、开阔视野，又可以扩充科技词汇，还能提高解 决这种的能力,何乐而不为？
结构:
标题(Headlines):文章中心思想高度而又精辟的概括，高考 这类阅读理解材料一般也不给标题，而要同学们选择标题 导语(Introductions):一般位于整篇文章的首段 背景(Background):交待一个事实的起因 主体(Main body):对导语概括的事实进行详细叙述 结尾(Ends):往往也是中心思想的概括，并与导语相呼应，命 题者常在此要设计一道推理判断题。
Before birth, babies can tell the difference between loud sounds and voices. They can even distinguish their mother's voice from that of a female stranger. But when it comes to embryonic learning (胎教)，birds could rule the roost. As recently reported in The Auk: Ornithological Advances, some mother birds may teach their young to sing even before they hatch(孵化). New-born chicks can then imitate their mom's call within a few days of entering the world. 本文的主题句: Babies can tell the difference between loud sounds and voices. 预测下文讲什么: An example will be given to show a new-born chick imitate his mom's call.

说明文是以说明为主要表达方式， 要求用简洁明快的语 言来解说事物、阐明事理， 从而给读者提供知识的一种文体。 近几年高考说明文多数以图表、表格或文字的形式给出提示， 并往往融合在应用文体中进行考查， 一般分为：场所路线介 绍；事物介绍；方式、方法或计划、安排介绍三大类。在写 作时要求语言简明扼要， 通俗易懂， 说明过程讲究层次性 和条理性。写作时要注意：
One possible version： 不需要发表主张， 抒发个人情感。
The burden of students has been a hot topic for years, but the load of parents has received little attention, especially from their 序。要特别讲究文章的层次和条理， 能反映客观事物本身逻辑顺序。对于不同的说明对象， 在 组织结构上可按时间、空间、结构、工艺程序、计划安排等 顺序来写。
2. 注意说明方法。可采用举例、比较、对比分析、叙述 等方式来描述， 可采取先举例后总结或者先总结后举例的 结构模式。不需要发表主张， 抒发个人情感。
