Why do many female athletes fall victim to knee injuries?
 
    Rebecca Lobo, a basketball star, grabbed a rebound¹ during the first seconds of game in June 1999. __1__.  A pain shot from her knee and drove Lobo to the floor. Tests revealed that Lobo had torn her anterior² cruciate （十字的，交叉的）ligament（韧带）, or ACL, resulting in the end of her play for the season. __2__
    Lobo, perhaps the most recognized player in the United States, is one of a growing number of female athletes suffering ACL injuries. Experts say that female athletes in middle school, high school, college and professional sports may be eight times as likely as male athletes to experience ACL injury.
    __3__. Why are so many female athletes falling victim to ACL injuries?
    Sports physicians say one reason is the growing number of females involved in high-impact sports, such as soccer and basketball. Jeff Bauer, a biochemist, however, thinks bone size plays a key role. He examined the knee joints³ of skeletons of 200 humans who had died at an early age.
    Studies of the skeletons of 100 males and 100 females showed in measurement after measurement that the bones making up a female’s knee are smaller than those of a male of the same size. Smaller bone surfaces may lead to an increase in stress placed on the ACL during sharp movements, such as turning, jumping, or stopping.
    Bauer thinks the size difference may be the primary reason that females injure their knees more often than males do with the same amount of training and experience. “Now, that’s not bad, ” adds Bauer, “and it’s not good. It’s just different.”
    Following the knee injury, Lobo underwent surgery. __4__. After the surgery, the patient needs months of physical therapy to strengthen the knee muscles and ligaments. Eight months after having knee surgery, the patient still needs to exercise her knee every day.
    __5__. They also recommend that players do stretching exercises before a game or a practice to help keep the knees flexible and more able to withstand stress during play.
 
Ａ　When she landed, she tried to stand firm but couldn’t.
B   One of the more common techniques used to repair a torn ACL involves replacing the entire ligament.
C   Sports injury experts say knee exercises may help protect knees from ACL injury.
D   Practice before and after a game is a good way to avoid injuries to knees
E  Thousands of female athletes have suffered a fate similar to Rebecca’s.
F  The ACL is a short band of tissue that keeps the knee stable during movement.

Rebecca Lobo, a basketball star, grabbed a rebound （蓝板球）during the first seconds of game in June 1999.__1__. Tests revealed that Lobo had torn her anterior（前面的） cruciate （十字的，交叉的）ligament（韧带）, or ACL, resulting in the end of her play for the season.　__2__. 
Lobo, perhaps the most recognized player in the United States, is one of a growing number of female athletes suffering ACL injuries.
１．　Ａ。　分析：因为空格１和空格２位于同一段落，所以可以考虑能否找到段落中心句？但是段首句是一个举例句，而空格２就是段未句。因为段落中Lobo反复出现，因此而推测该段的中心是对Rebecca Lobo进行介绍，而被选项中涉及到Lobo的只有的Ａ和Ｅ。首先重点注意这两个选项。空格１的前句说“Lobo在开赛的前句秒中抢到了蓝板球”，空格后句说“从膝盖传来了疼痛，Lobo摔到了地下”，这些都是在对具体细节进行描述，因此判断Ａ（细节描述句）是答案。
物以类聚—相似的结构，相同的词语／词义相近的词语往往“聚在一起”，　如都是观点句，都是举例句等；
 
２．　F  分析：E位于空格２处似乎很合适：前句中谈到了“Lobo的命运”－－但是空格２后面的句子已经说了“Lobo只是受到ＡＣＬ伤的越来越多的女性运动员中的一个”，所以Ｅ和空格２后句的内容“重复了”，因此判断Ｅ不是答案。注意空格前的词语特点：空格２前句中出现了专有名词，而空格处出现定义性的结构很可能，所以判断Ｆ是答案。
 
B   One of the more common techniques used to repair a torn ACL involves replacing the entire ligament.　
C   Sports injury experts say knee exercises may help protect knees from ACL injury.　观点
D   Practice before and after a game is a good way to avoid injuries to knees观点
E  Thousands of female athletes have suffered a fate similar to Rebecca’s.　事实陈述
 
__3__. Why are so many female athletes falling victim to ACL injuries?
3. Ｅ。　分析：空格后面是一个问句“为什么这么多的女性运动员都深受ACL伤之害”，提出问题往往是针对某个现象提出的，因此判断Ｅ（陈述了严峻的事实情况）是答案。
 
B   One of the more common techniques used to repair a torn ACL involves replacing the entire ligament.　
C   Sports injury experts say knee exercises may help protect knees from ACL injury.　观点
D   Practice before and after a game is a good way to avoid injuries to knees观点
    Following the knee injury, Lobo underwent surgery. __4__ After the surgery, the patient needs months of physical therapy to strengthen the knee muscles and ligaments. Eight months after having knee surgery, the patient still needs to exercise her knee every day.
4. Ｂ。分析：注意到空格前后都出现了surgery，因此空格处很可能出现与“手术”有关的句子，因此判断Ｂ（修补撕裂的ＡＳＬ与“手术”呼应）是答案。
 
C   Sports injury experts say knee exercises may help protect knees from ACL injury.　观点
D   Practice before and after a game is a good way to avoid injuries to knees观点
    __5__. They also recommend that players do stretching exercises before a game or a practice to help keep the knees flexible and more able to withstand stress during play.
5. Ｃ。分析：空格后面出现了“他们也建议”，因此判断Ｃ是答案
