You may think that sailing is difficult, 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(帆).

　 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 (角度) 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 (擺動(dòng)). It shouldn’t look like a flag 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.

64. What should you consider first while sailing?

　 A. Sailors’ strength.

　 B. Wave levels.

　 C. Wind directions.

　 D. Size of sails.

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

　 A. The sail.

　 B. The wind.

　 C. The boat.

　 D. The angle.

66. 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.

　 【語篇解讀】本文是一篇說明文。文章介紹了帆船運(yùn)動(dòng)的一些常識(shí)，進(jìn)行帆船運(yùn)動(dòng)必須掌握風(fēng)向，風(fēng)向決定著帆船的運(yùn)動(dòng)速度。后文分別就順風(fēng)行駛、側(cè)風(fēng)行駛和逆風(fēng)行駛進(jìn)行了闡述。

64.C【命題立意】考查考生對(duì)具體信息的理解能力。

【試題解析】根據(jù)第二段中的 “First, you must ask yourself, “Where is the wind coming from? Is it coming from ahead or behind or from the side?” 可知風(fēng)向是決定帆船的最重要因素。

65.A【命題立意】考查考生猜測(cè)詞義的能力。

　 【試題解析】根據(jù)文章中的“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 (擺動(dòng) ).”可知it指代the sail。

66.D【命題立意】考查考生的推理判斷能力。

　　　 【試題解析】根據(jù)文章最后一段中的“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.”所以選D。 tack the boat意為：改變船航向。

閱讀理解

　　You’ve probably heard a lot about the Internet, but what is it?

　　The Internet is a computer network that uses the telephone system to link together millions of computers around the world．

　　Maybe that doesn’t sound exciting, but once you’re connected to the Internet, there are lots and lots of different things you can do．You can send electronic messages or “E-mail” to your friends(as long as they’re on the Internet too), or you can sort(挑出, 揀出)through all sorts of information on something called the World Wide Web．

　　You don’t need to know how the Internet works in order to use it, but if you understand the basics, it may help you solve any technical problem you have－and of course you can impress your friends with your Net knowledge!

　　You may think that your telephone is just for talking．But as long as you have the right equipment, you can use a telephone line to transmit computer data(數(shù)據(jù))as well as sounds．If you plug your computer into the telephone system it can receive information from and send information to other computers(as long as they are plugged into the telephone system too)．

　　Computer data is made up of electronic signals(訊息)．A computer language called TCP/IP

　　(which stands for Transmission Control Protocol/Internet Protocol, if you like to know these things)is used to move computer data around the Internet．Many of the links, for example, those which send out computer data across the Atlantic Ocean, are special fiber optic cables(光導(dǎo)纖維電纜),

　　fiber optic cables use light to send out information．They can carry a lot more data than an ordinary telephone line and they send it a lot faster!
