根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。Rock Climbing as Sport and Art
An estimated nine million people rock climb in the United States. Millions more take part in the activity around the world. 小题1: Others compete. Rock climbing can be dangerous. But there are many methods and protective devices that can increase a climber’s safety.
小题2: Climbers have to pull themselves straight up the face of very high rocks or walls. So they have to be strong enough to carry their own weight. And climbers sometimes have to hold on to rocks with only their fingers or toes.
There are several kinds of rock climbing. Traditional rock climbing is done outside. Climbers wear ropes and attach devices to the rocks as they climb many hundreds of meters up. They also connect their ropes to the devices. 小题3: Sport climbing is similar. However, in those cases the protective devices are permanently placed in the rock. There is also indoor climbing. Rock walls made of wood or concrete have places for the climber’s hands and feet.
小题4: People climb glaciers or frozen waterfalls instead of rocks. They use special equipment for the ice.
And then there is bouldering（巨石攀岩）— climbing rocks between three and seven meters high. 小题5: Many climbers like bouldering because they can use less equipment. Climbers often need only special shoes and chalk. All climbers use chalk to keep their hands dry.A．Ice climbing is exactly as it sounds.B．Some do it just for personal satisfaction.C．Some go climbing at weekends or in holidays.D．It is a quicker and more intense（剧烈的；紧张的）kind of climbing.E. If a climber slips, a rope can stop him from falling.
F. Climbing takes strength, control and good balance.
G. It is more challenging and dangerous, but also more fun. 题型：未知难度：其他题型

考点
据考高分专家说，试题“根据短文内容，从短文后的选项中选出能填入.....”主要考查你对 [序数词 ]考点的理解。序数词
序数词的概念：
表示顺序的数称为序数词。如：first, second, third, fourth。
序数词的构成与用法：
1、序数词的构成：
①一般来说，是由相应的基数词加词尾th构成。
例：four＋th→fourth
six＋th→sixth
seven＋th→seventh
ten＋th→tenth
②下面这些基数词在变为序数词时，有特殊的变化。
例：one→first
two→second
three→third
five→fifth
eight→eighth
nine→ninth
twelve→twelfth
③十位整数序数词的构成方法是将基数词的词y变成i，然后再加eth。
例：twenty→twentieth
thirty→thirtieth
forty→fortieth
ninety→ninetieth
④两位或两位以上的基数词变成序数词时，仅将个位数变成序数词。
例：twenty－one→twenty－first
thirty－five→thirty－fifth
a hundred and fifty－three→a hundred and fifty－third
2、序数词的用法：
①序数词在使用时，一般加上定冠词。
例：the first book
the second floor
the third day
the fourth week．
②序数词在多数情况下都用作定语，有的也可以作表语、主语和宾语。
例：The may1st is Labour Day. 五月一日是劳动节。
My room is on the second floor. 我的房间在二楼。
The first is larger than the secon.（主语）第一个比第二个大。
Read the book from the first.（宾语）从开头读这本书。
You'll be the sixth to write.（表语）你将是第六个写的。
③序数词的前面可以加上不定冠词，用来表示“再一”，“又一”的意思。
例：You may have a third try. 你可以第三次尝试。
序数词知识体系：
约数的表达方法：
用tens/dozens/scores/hundreds/thousands/millions of 表示“几十、几百、上千、成千上万”等。
如：The boy bought dozens of pencils.
Thousands of people died in the earthquake.
注意： (A)：dozen, score, hundred, thousand, million等表示确切数量时，不用复数。
如：five dozen (of) eggs 五打鸡蛋
hree hundred people 三百个人
分数词的构成和用法：
1）分数词构成法：
分数词（FractionalNumerals）由基数词和序数词构成，基数词代表分子，序数词代表分母。除了分子为1的情况下，序数词都要用复数形式：
如：1/4：one-fourth
5/9：five-ninths
2/3：two-thirds
17/5：three and two-fifths
7/12：seven-twelfths
379/8：forty-seven and three-eighths
此外还有下面表示法：
如：1/2：a(one) half
1/4：a(one) quarter
3/4：three-quarters
9/4：two and a quarter
3/2：one and half
31/4：seven and three quarters
