Passage One
Questions 21 to 25 are based on the following passage:

　　Dogs are social animals and without proper training, they will behave like wild animals. They will soil your house, destroy your belongings, bark excessively, fight other dogs and even bite you. Nearly all behavior problems are perfectly normal dog activities that occur at the wrong time or place or are directed at the wrong thing. The key to preventing or treating behavior problems is learning to teach the dog to redirect its normal behavior to outlets that are acceptable in the domestic setting.
　　One of the best things you can do for your dog and yourself is to obedience train（驯服） it. Obedience training doesn’t solve all behavior problems, but it is the foundation for solving just about any problem. Training pens up a line of communication between you and your dog. Effective communication is necessary to instruct your dog about what you want it to do.
　　Training is also an easy way to establish the social rank order. When your dog obeys a simple request of “come here, sit,” it is showing obedience and respect for you. It is not necessary to establish yourself as top dog or leader of the pack（群）by using extreme measure. You can teach your dog its subordinate（从属的）role by teaching it to show submission to you. Most dogs love performing tricks for you to pleasantly accept that you are in charge.
　　Training should be fun and rewarding for you and your dog. It can enrich your relationship and make living together more enjoyable. A well-trained dog is more confident and can more safely be allowed a greater amount of freedom than an untrained animal.

答案:
翻译：狗是群居动物，但如果没有适当训练，它的行为就像野生动物一样。
　　文章有四段，定位比较容易，可以按顺序原则来逐个找答案。
　　21.定位在第一段；几乎所有的行为问题都是狗的正常活动，只不过是搞错了时间或地点或对象。A：狗狗天性的一部分。就是对这句话的同义转述；B：将会恶化。文章没有提及；C：当狗狗变的野蛮的时候发生。行为问题是狗狗的正常活动，应该一直都有的吧~；D：显示对社区的威胁。文章也没有提及。所以答案是A。
　　22.定位在第二段，但是驯服的目的在第一段最后一句：The key。。。is learning to。。。表目的：将其正常的行为改成在家庭环境下可以接受的发泄。A：教狗狗表演机灵的花样。这是后面提及的细节。B：让狗狗意识到主人的权威。也是后面提及的内容，不是目的。C：给狗狗发泄它的野蛮行为。就是驯服的目的吧。D：使狗狗恢复正常行为。这本来就是狗狗的正常行为呀。所以答案是C。
　　23.定位在第二段最后一句：有效的沟通是命令狗狗做事所必须的。A：解决狗狗行为问题所必须的。文章没有说必须这个意思。B：让狗狗完成任务的基础。任务就是你让狗狗做的事，和定位的句子是一个意思，只是换了一个说法。C：教狗狗新花样的方法。文章没有说到。D：是驯服的极端措施。交流怎么会是极端措施呢？而且极端措施也是出现在后面的内容，还是not necessary 。所以答案四B。
　　24.定位在第三段最后一句：愉快地承认你是管事人（负责人）to表原因。A：避免受罚。文章没有提到。B：显示对主人的感情。文章也没有提到，文章只说服从简单要求显示对主人的服从和尊重，而不是表演花样。C：赢得狗群的领导地位。文章说主人不必要做狗狗的领导。D：显示愿意服从。和定位的句子是一个意思。所以答案是D。
　　25.定位在第四段最后一句：一只训练有素的狗更自信，给它更多的自由时会比未经训练的狗更安全。A：主人能给狗狗更多奖赏。B：主人能享受更好的家庭生活。C：主人能给狗狗更多自由。D：主人更有自信。只有C是定位句子的同义转述，所以答案是C。
　　五个题目有四个分别对应每段的最后一句，而且都是对原话的同义转述，不会出现原话。所以选项里面如果出现文章中的原话，一般都是干扰选项，正确答案总是换一种说法来表达。而且一旦定位在某一段以后，在别的段落出现的内容一般是干扰选项。
