Chuck Wall teaches management and human relations at Bakersfield College. He walked into class one day and told his students that their homework was to perform one act of random(任意的) kindness. His students did not understand the homework and didn’t know what to do, but the professor would not answer their questions. He encouraged his students to work it out for themselves.
One week later, the students entered the classroom excited to share their stories. One student told of giving away blankets to the homeless. Another reported on helping a dog to find its owner, and another student had been trying to find a long, lost friend. Students were energized (给予活力) by the homework assignment and wanted other people to be kind too. With the support of local businesses, the students made stickers to put on cars that invited people to do something kind for others. They sold the stickers and decided to donate the money to a center for the blind---not surprising as Professor Wall is blind.
Since then, similar kindness activities have been started in schools around the world. Many schools organize a Random Acts of Kindness Week, around November 13^th, to celebrate World Kindness Day. Some schools use each day of Random Acts of Kindness Week to perform a different kind act, such as making a new friend, helping someone, doing community service, or raising money for a charity. Students learn to consider other people and thank about how small actions can make the world a better place.
【小题1】The professor’s homework was to ask his students _________.

We sometimes call the lion “the king of the jungle (丛林)” because it is stronger and more dangerous than other animals. It can run faster than many animals and it can hunt (捕猎) the best. It is the highest animal in the   21  food chain (食物链).[

         In the sea, the shark is one of the animals at the  22  of the food chain. It can swim faster than most other sea animals, and it can use its big teeth to eat them.

         What is at the top of the world’s food chain?  23  are! We are not the biggest or fastest, but we are the   24  We could not run faster than cheetahs (猎豹),  so we  25  cars and now we can move the fastest. We could not  26   better than lions, so we invented guns (枪). Now we can hunt the best.

People’s inventions are clever, but they can be dangerous, too. For example, people invented  27 , and now they make the air and rivers dirty. This can make   28  changes. Dirty rivers kill fish.  Then bears cannot eat the fish and the bears die. If we kill one part of the food chain,   29   also die. Remember that we are a part of the food chain, so we are in danger too! If we protect animals, we are protecting   30  ! We should and we could do something for the world!

Dear editor( 编辑),       

Can't your newspaper do something about the custom (习惯) of hitchhiking?

A short time ago, on a car travel I counted at least 50 people standing beside the road, asking for rides. Many of them were young women.

Don't they understand how dangerous it is to get into the car driven by a stranger? How much do they know about the driver? Is he a good driver or not? They know nothing!

Many of these young hitchhikers may come from good families. Don't their parents teach them anything about the world? I always taught my children not to talk to strangers. I never let them take rides from people they didn't know.

Isn't there enough crime (犯罪) today without asking for trouble by hitchhiking? On the other hand, hitchhiking may bring some traffic trouble. Don't you think what I said is true?
