Question

12．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 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）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）．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．

29．What should you consider first while sailing？D
A．Wave levels．
B．Size of sails．
C．Sailors'strength．
D．Wind directions．
30．What does the word"It"underlined in Paragraph 4 refer to？C
A．The boat．B．The wind．C．The sail．D．The angle．
31．What do you have to do when sailing against the wind？A
A．Tack the boat．
B．Lower the sail．
C．Move in a straight line．
D．Allow the sail to flap．
32．Where can you probably find the text？C
A．In a physics textbook．
B．In a tourist guidebook．
C．In a popular magazine．
D．In an official report．

Answer 1

分析 本文是一篇說明文．文章介紹了帆船運動的一些常識，進行帆船運動必須掌握風向，風向決定著帆船的運動速度．后文分別就順風行駛、側風行駛和逆風行駛進行了闡述．

解答 29．D   細節(jié)理解題．根據第二段中的"First，you must ask yourself，"Where is the wind coming from？Is it coming from ahead or behind or from the side？""可知，風向是決定帆船最重要因素．
30．C   猜測詞義題．根據文章中的"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）．"可知，it指代the sail．
31．A   推理判斷題．根據文章最后一段中的"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A．tack the boat意為：改變船航向．
32．C  推理判斷題． 帆船運動是普通的一種體育運動，因此，本文很可能從流行雜志中節(jié)選．故選C．

點評 本文是一個人生感悟類閱讀，題目涉及多道細節(jié)理解題，做題時結合原文和題目有針對性的找出相關語句進行仔細分析，結合選項選出正確答案．推理判斷題也是要在抓住關鍵句子的基礎上合理的分析才能得出正確答案，切忌胡亂猜測，一定要做到有理有據．
