Question

You may think that sailing is a difficult sport, but it is really not hard to learn it. You do not need to be 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.

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 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(角)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°an-gle to the boat. It needs to be out far enough to catch the wind, but it shouldn't flap(擺動(dòng)).It shouldn't look like a flag on a flagpole. If it is flap?ping, 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 anoth?er. This is called tacking. When you are tacking, you must always keep the sail inside the boat.

5. What should you consider first while sailing?

  A. Sailors' strength.

B. Wave levels.

C. Wind directions.

D. Size of sails.

6. What does the underlined word "It" in Paragraph 4 refer to?

  A. The boat.

B. The wind.

C. The sail.

D. The angle.

7. 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.

8. 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

5. C

6. C代詞指代題。結(jié)合第四段的"In this case,you must keep the sail half way outside the boat."中的the sail可知 后面的it指的是"風(fēng)帆"，而不是"船"，"風(fēng)"或"角"。

7.D細(xì)節(jié)理解題。從最后一段的"You may want to go in that direction- This is called tacking."可知逆風(fēng)航行的B才候要不斷地改變方向，因此選D。

8.A推理判斷題。本文主要涉及大眾的航行運(yùn)動(dòng)的知識(shí)，而不是有關(guān)旅游和物理方面的知識(shí)，也不是一個(gè)官方的報(bào)告，因此選A。
