Question

【题目】You may think that sailing is a difficult sport, but it is really not hard to learn it. 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 are tacking, you must always keep the sail inside the boat.

【1】What should you consider first while sailing?

A. Sailors’ strength B. Wave levels

C. Wind directions D. Size of sails.

【2】What does the word “It” underlined in Paragraph 4 refer to?

A. The boat B. The wind

C. The sail 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. Lower the sail.

D. Tack the boat.

【4】Where can you probably find the text?

A. In a popular magazine. B. In a tourist guidebook.

C. In a physics textbook. D. In an official report.

Answer 1

【答案】

【1】C

【2】C

【3】D

【4】A

【解析】

试题分析：这是一篇说明文。文章主要讲了航海作为一项运动，在其过程中需要注意的地方及遇到问题时所应采取的解决办法。

【1】细节理解题。由第二段可知：航海最首先要考虑的是风的方向，因为风的方向会告诉你帆应该怎么处理。故选C。

【2】词义猜测题。由前一句“In this case, you must keep the sail half way outside the boat. It should be at a 45° angle to the boat.”在这种情况下，你必须保持风帆有一半在船外，它应该是与船呈45°角，可知，这里it指的是风帆，所以后文紧接着的it同样是指风帆。故选D。

【3】细节理解题。由第五段“ Sailing into the wind is not possible. If you try, the sail will and the boat will stop. You may 可知，风帆卷进风里是不可能的，如果你尝试了，风帆则会飘动，船也不会动了。这就是风帆与风在对抗。由后文“ You must go first in one direction and then in another. This is called tacking.”可知，在这种情况下，你必须往一个方向走然后转另一个方向，这就叫做顶风转向。故选D。

【4】推理判断题。A流行杂志；B旅游指南；C物理课本；D官方报告。由全文大意可知，文章讲的是关于航海这一运动的，是一种当下比较流行的运动。故选A。
