Question

You may think that sailing is a difficult sport, but it is really not hard to learn. You do not need to be strong. But you need to be quick. And you need to understand a few basic rules about the wind.

First, you must ask yourself, “Where is the wind coming from? Is it coming from ahead or behind or from the side?” You must think about this all the time on the boat. The wind direction tells you what to do with the sail.

Let’s start with the wind blowing from the behind. This means the wind and the boat are going in the same direction. Then you must always keep the sail outside the boat. It should be at a 90° angle to the boat. Then it will catch the wind best.

If the wind is blowing from the side, it is blowing across the boat. In this case, you must keep the sail half way outside the boat. It should be at a 45°angle to the boat. It needs to be out far enough to catch the wind, but it shouldn't flap(摆动). It shouldn’t look like on a flagpole. If it is flapping, it is probably out too far, and the boat will slow down.

Sailing into the wind is not possible. If you try, the sail will flap and the boat will stop. You may want to go in that direction. It is possible, but you can’t go in a straight line. You must go first in one direction and then in another. This is called tacking. When you’re tacking, you must always keep the sail inside the boat.

1.What should you consider first while sailing?

A. Sailors’ strength.

B. Wind directions.

C. Size of sail.

D. Wave levels.

2.What does the word “It” in Paragraph 4 refer to?

A. The sail.B. The wind.C. The boat.D. The angle.

3.What do you have to do when sailing against the wind?

A. Move in a straight line.

B. Allow the sail to flap.

C. Tack the boat.

D. Lower the sail.

4.Where can you probably find the text?

A. In a tourist guidebook.

B. In a physics textbook.

C. In an official report.

D. In a popular magazine.

【解析】

试题分析：本文讲述了帆船运动与风向的关系，并讲述了如何掌握好风向航行。

1. 事实细节题。根据文章内容以及常识可知，在做帆船运动时首先应该考虑“风向”。故选B。

2. 推理判断题。根据In this case, you must keep the sail half way outside the boat.可知，it指代the sail。故选A。

3. 事实细节题。根据最后一段中...but you can’t go in a straight line.可知，A项错误。根据第四段可知，D项错误。根据最后一段“If you try, the sail will flap...”可知，B项错误。根据最后一段的描述可知，C项正确。

4. 推理判断题。本文主要介绍的是帆船运动与风向的关系，由此可推知本文应出自杂志，而不是出自旅游指南、物理教科书，更不可能出自官方报告。

【名师点睛】

科普类文章是高考英语的常考题材，这类文章的总体特点是：科技词汇多，句子结构复杂，理论性强，逻辑严谨。具体说来它有以下几个特点：1. 文章中词汇的意义比较单一、稳定、简明，不带感情色彩，具有单一性和准确性的特点。这类文章通常不会出现文学英语中采用的排比、比喻、夸张等修辞手法，一词多义的现象也不多见。2. 句子结构较复杂，语法分析较困难。为了描述一个客观事物，严密地表达自己的思想，作者经常会使用集多种语法现象于一体的长句。3. 常使用被动语态，尤其是一些惯用被动句式。

三、命题特点科普类阅读的主要命题形式有事实细节题、词义猜测题、推理判断题以及主旨概括题等，其中推理判断题居多。

四、应对策略1. 要想做好科普英语阅读理解题，同学们就要注意平时多读科普知识类文章，学习科普知识，积累常见的科普词汇，从根本上提高科普英语的阅读能力。2. 要熟悉科普类文章的结构特点。科普类文章一般由标题(Headlines)，导语(Introductions)，背景( Background)，主体(Main body)和结尾(Ends)五部分构成。标题是文章中心思想高度而又精辟的概括，但根据历年的高考真题情况来看，这类阅读理解材料一般不给标题，而要同学们选择标题。导语一般位于整篇文章的首段。背景交待一个事实的起因。主体则对导语概括的事实进行详细叙述。这一部分命题往往最多，因此，阅读时，同学们要把这部分作为重点。结尾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。3. 在进行推理判断时，同学们一定要以阅读材料所提供的科学事实为依据，同时所得出的结论还应符合基本的科普常识。
