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 spboil 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 us 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 opens 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 o
beys 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 dog pack (群) by using extreme measures. 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.

Passage Two
Questions 26 to 30 are based on the following passage.
    Engineering students are supposed to be examples of practicality and rationality
, but when it comes to my college education I am an idealist and a fool. In highschool I wanted to be an electrical engineer and, of course, any sensible student with my aims would have chosen a college with a large engineering department,famous reputation and lots of good labs and research equipment. But that's not what I did.
    I chose to study engineering at a small liberal |arts(文科) university that doesn't even offer a major in electrical engineering. Obviously, this was not a practical choice; I came here for more noble reasons. I wanted a broad education that would provide me with flexibility and a value system to guide me in my career. I wanted to open my eyes and expand my vision by interacting with people who weren't studying science or engineering. My parents, teachers and other adults praised me for such a sensible choice. They told me I was wise and mature beyond my 18 years, and I believed them.
    I headed off to college sure I was going to have an advantage over those students who went to big engineerng "factories" where they didn't care if you had values or were flexible. I was going to be a complete engineer: technical genius and sensitive humanist(人文学者) all in one.
    Now I'm not so sure. Somewhere along the way my noble ideals crashed into reality, as all noble ideals eventually do. After three years of struggling to balance math, physics and engineering courses with liberal arts courses, I have learned there are reasons why few engineering students try to reconcile (协调) engineering with liberal |arts courses in college.
    The reality that has blocked my path to become the typical successful student is
that engineering and the liberal arts simply don't mix as easily as I assumed in high school. Individually they shape a person in very different ways; together they threaten to confuse. The struggle to reconcile the two fields of study is difficult.
