A
Raised in a fatherless home, my father was extremely tightfisted towards us children. His attitude didn’t soften as I grew into adulthood and went to college. I had to ride the bus whenever I came home. Though the bus stopped about two miles from home, Dad never met me, even in severe weather. If I grumbled, he’d say in his loudest father-voice, “That’s what your legs are for!”
The walk didn’t bother me as much as the fe ar of walking alone along the highway and country roads. I also felt less than valued that my father didn’t seem concerned about my safety. But that feeling was canceled one spring evening.
It had been a particularly difficult week at college after long hours in labs. I longed for home. When the bus reached the stop, I stepped off and dragged my suitcase to begin the long journey home.
A row of hedge（树篱）edged the driveway that climbed the hill to our house. Once I had turned off the highway to start the last lap of my journey, I always had a sense of relief to see the
hedge because it meant that I was almost home. On that particular evening, the hedge had just come into view when I saw something gray moving along the top of the hedge, moving toward the house. Upon closer observation, I realized it was the top of my father’s head. Then I knew, each time I’d come home, he had stood behind the hedge, watching, until he knew I had arrived safely.
I swallowed hard against the tears. He did care, after all.
On later visits, that spot of gray became my watchtower. I could hardly wait until I was close enough to watch for its secret movement above the greenery. Upon reaching home, I would find my father sitting innocently in his chair. “So! My son, it’s you!” he’d say, his face lengthening into pretended surprise.
I replied, “Yes, Dad, it’s me. I’m home.”

I have been teaching animal behavior at the Boulder County Prison in Colorado for 10 years. The course is one of the most popular in the prison. Prisoners have to earn the right to attend the course and they work hard to get in.
One reason why the course is so popular is that many prisoners find it easier to connect with animals than with people, because animals don’t judge them. They trust animals in ways they don’t with humans.
Yet, they hold a misunderstanding of how animals treat one another. Many admit that their own “animal behavior” is what got them into trouble in the first place. I teach that though there is competition and aggression in the animal kingdom, there is also a lot of cooperation（合作）and sympathy.
Many of the students want to build healthy relationships, and they find that the class helps them. I use examples of the social behavior of group-living animals such as wolves as a model for developing and maintaining（维持）friendships among people who must work together for their own good and also for the good of the group.
It’s clear that science inspires the students here and it also gives them hope. I know some students have gone back into education after their being set free while others have gone to work for humane（人道）societies or contributed time and money to conservation organizations. One went on to receive a master’s degree in nature writing.
Science and humane education help the prisoners connect with values that they otherwise would not have done. It opens the door to understanding, trust, cooperation and hope. There’s a large population of people to whom science could mean a lot, if only they could have access to it. The class helps me, too. I get as much out of it as the students and it has made me a better teacher. 本文是教育类小故事阅读。作者用和动物之间的关系来教育那些囚犯们，没想到却让他们的生活翻开了新的一页。人是可以教得好的。
25. The author’s course is welcomed by the prisoners because ______.

Windows 8, apart from Windows 95, is the biggest surprise and the only version of Microsoft’s operating system that has been changed from the core（核心）when compared to its former one. However, a recent study has shown that under 20% of business owners would be willing to upgrade to the new version of Windows. The reason for this remains to be discussed and debated, and we will try to throw light on this research by providing you with some of the most common advantages and disadvantages of Windows 8.

Speed—This is the biggest advantage to mention. Boot time has been reported to be up to nine times shorter than that with Windows 7.
New passwords—Instead of typing your passwords, Windows 8 will let you use gestures on your favorite photos to enter your password. This is not only practical but also extremely cool!
Windows 8 experience—Apart from computers, Windows 8 will be used on all devices, including smart phones, tablet PC’s and so on. Also, owing to the fact that it has been specifically designed with touch screen users in mind, Windows 8, besides using keyboard and mouse, will offer a whole new user experience.
However, there are still some disadvantages.
The first one that has to be mentioned is that there is no Start Menu from Windows. Yes, there is no Start button in the lower left corner, and this might be a real puzzle of many Windows users. Also, many users have had a problem to get used to the new interface（界面）introduced by Windows 8. The biggest problem that is worth noticing is that Windows 8 was originally designed for touch screen users, and this may have a bad effect on desktop users who have gotten used to doing everything with the help of their keyboard and mouse.

You often find somebody who works around you complaining all the time, don’t you?
36 About 70% of Americans say being around nonstop complainers sometimes has a bad influence on them. Luckily, here are 4 tips to help form positive patterns.
1. Self-awareness
When a negative thought pops into your mind, immediately correct it. Instead of telling yourself “That’s a nice shirt, but I can’t afford it,” change the message to “That will look great with my black pants when I can afford it.” 37
Of course, everyone complains sometimes. But the less frequently you complain, the better
2. Distance yourself
38 Excuse yourself and go somewhere quiet, somewhere outdoors in the fresh air. Think of something pleasant before returning. You have to take this seriously because negative people can and will pull you into the quicksand（困境）.
3. Don’t try to change complainers
If you find yourself trapped in a group of complainers in a meeting or at a social event, simply choose silence. Let their words bounce off you while you think of something else. Attempting to stop the complaining can make you a target. 39 If someone says, “I hate Mondays, weekends are too short,” try to think, “I’m glad I rested up over the weekend, so I’m ready to make some improvement on that big project.”
4. 40
When someone is shouting at you angrily, throw the responsibility back at them by asking, “So what do you intend to do about it?” In most cases, complainers don’t really want a solution. They just want to speak them out. If you make them aware that they themselves have to find the solutions, they will leave you alone and find someone else to complain to. If so, you will be happy.
A. Find solutions
B. Change responsibility
C. You have got a lot of company.
D. By doing this, it will lead to positive behaviors.
E. But you can redirect the discussion in your own mind.
F. Whenever possible, escape from negative conversations.
G. You will never know what they are going to talk about.
【语篇解读】本文是一篇议论文，告知读者建立积极的态度。
36.【答案】C
【考点】考查考生对上下文顺承关系的理解能力。
【解析】由前一句“You often find somebody who works around you complaining all the time”和后一句“About 70% of Americans say…”可知。故选C。

【解析】根据上文change the message to “That will look great with my black pants
when I can afford it”可知，这种想法会帮助我们建立积极的态度。故选D。
38. 【答案】F
【考点】考查考生对上下文顺承关系的理解能力。
【解析】从标题句Distance yourself和本段最后“because negative people can and
will pull you into the quicksand”，可知要远离消极的人，故选F。
39. 【答案】E

【解析】根据本段最后一句的举例“ I’m glad I rested up over the weekend,
so I’m ready to…”可知要从不同的角度思考。故选E。

As an old English saying goes, “honesty is the best policy”. It is more than an old cliché（陈词滥调）, but 61 good way to live your life.
First, honesty is the 62 (easy) choice that we can make. When people get caught in lies, it always costs them something. Many relationships are destroyed by lies.
Second, honesty gives us much 63 (free). Many people believe that being honest limits them in life, but that is not true. Sooner or later those dishonest people 64 (pay) a price for their acts; on the contrary, when we are honest, we are 65 (true) free.
If there were two people 66 (stand) before you, a person with a record of being honest and a person 67 is known to be dishonest, who would you be more likely
68 (believe)? I’m sure most people would side with the honest person. 69 we live in the truth or we live in lies. Truth sets us free and lies leave us in nothing but more troubles. Honesty is a choice that we make each day. The choice is 70 (you). What will you choose?
本文是议论文，论述“honesty is the best policy”。
