1、Module 4 Great Scientists.阅读理解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 com
2、ing 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.Lets 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 outsid
3、e 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 half of the sail outside the boat.It should be at a 45 angle to the boat. It needs to be out far enough to catch the
4、 wind, but it shouldnt flap (摆动) or look like a flag on a flagpole.If it is flapping, it is probably out too far, and the boat will slow down.Sailing against the wind is not impossible.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
5、 cant go in a straight line.You must go first in one direction and then in another.This is called tacking(抢风航行). When you are tacking, you must always keep the sail inside the boat.本文是一篇说明文，介绍了帆船运动的一些常识。进行帆船运动必须要注意风向，因为风向决定着要如何操纵船帆。1What should you consider first while sailing?ASailors strength. BWa
6、ve levels.CWind directions. DSize of sails.答案：C解析：细节理解题。根据第二段中的“First，you must ask yourself，Where is the wind coming from？Is it coming from ahead or behind or from the side？”，可知，风向是进行帆船运动很重要的因素。2What does the underlined word “It” in Paragraph 4 refer to?AThe boat. BThe wind.CThe sail. DThe angle.答案：
7、C解析：代词指代题。根据文章第四段中的“you must keep half of the sail 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 shouldnt flap (摆动)”可知，It指代的是船帆。3What do you have to do when sailing against the wind?AMove in a straight line. BAllow the sail to flap.CLo
8、wer the sail. DTack the boat.答案：D解析：推理判断题。根据文章最后一段中的“It is possible，but you cant go in a straight line. You must go first in one direction and then in another.This is called tacking(抢风航行)”可知，逆风行驶的时候需要改变航向，这叫作tacking。故推断，逆风行驶时要tack the boat(使船曲折航行)。4Where can you probably find the text?AIn a popular
9、magazine. BIn a tourist guidebook.CIn a physics textbook. DIn an official report.答案：A解析：出处判断题。文章第一段开门见山地指出帆船运动不难，只是需要反应敏捷，后文中又指出了了解风向的重要性，以及如何抢风航行，由此可推断本文可能出自“通俗杂志”，而不是“旅行指南”“物理课本”或“官方报道”。故选A。.语法填空阅读下面短文，在空白处填入适当的内容(1个单词)或括号内单词的正确形式。APEC，_1_(establish) in 1989, is short_2_AsiaPacific Economic Cooper
