When three of my grandchildren acquired a half－grown dog I agreed to help them build a dog house. As we began the __1__， I knew that keeping them involved was going to be a __2__. Much of my energy was spent calling them back to the job and finding __3__ of the project that could be handled by small children. I held to my initial(最初的) determination that building this dog house was to be a (n) __4__  project.

Early in the project I had __5__ the grandkids that we would roast wieners(香肠) in the back yard __6__ we finished painting the dog house.__7__ three of the largest house－painting brushes I could find, I supervised (管理) the __8__ of our homemade structure. Kids and paint. How could I have __9__ the potential (潜在的) harm that such a combination can create?

After cleaning up the paint __10__－kids, brushes, carport(车棚)－I __11__ that we would probably eat earlier if we just asked Grandma to heat the wieners in water on the gas range. A pain of __12__ came over me as I realized I was trying to weasel(躲避) out of a(n)__13__ promise.

As Jamie, Jeffrey and Kimberley looked on, I built a first－class fire in our back yard pit, cut some roasting sticks, and prepared for the __14__ cooking event. When we __15__ eating I leaned back on the cool grass and __16__ the last remnants(残余) of our fire. Six－year－old Jeffrey was leaning back against my chest, and I began to think about what it meant to be a Grandpa.

The __17__ was broken when Jeffrey quietly reflected, “Know what Grandpa？” And without breaking his __18__ at the dying embers(灰烬) he continued, “This is the best day of my whole life.”

After a few moments of __19__ silence he glanced up and said, “Are you crying, Grandpa? You've got a __20__ on your cheek.”

Clearing my throat I explained that it must be from the smoke.

All kids need to be motivated to learn while some kids have to be tricked into learning.

I taught kids in high school for the past ten years. The first couple of years, I 36 as if I was knocking my head 37 a wall. Nobody cared about learning and a lot of anger was 38 .When I left school,I found my car with flat tires. I was still 39 not to give up. The next week, my car was 40 with eggs that would not come off. This type of behavior was common and 41 .

Then one day, I decided to motivate the kids. I made a 42 that if everyone in the class 43 the semester with an 80% or better, I would 44 them to egg my car all they wanted to one day. If the class 45 a 90% or better, they could cut its tires 46 they turned into rubber bands. The kids took the 47 and left my car alone for the whole semester. They studied hard and helped each other to learn.

The last day came, and to my excitement, every student 48 above 90% for the semester. Then the kids 49 out twelve boxes of extra large eggs. Ten minutes later, the car was 50 trapped in eggs. The tires looked like rubber bands !

I thought it was 51 . The kids learned, and I only had my car 52 twice a year. I have made this bet for the past ten years with no 53 and 100% success. The moral of the story is that you must find what motivates the students at all 54 . I still drive my Camaro, and I was never able to fully clean the eggs off. It’s a 55 of their success!

If a noisy neighbor is blasting music at all hours of the day and night, drowning out your phone conversations and interrupting your sleep, you can call the police. But what is a whale to do?
Natural noise from waves, wind, rain and even earthquakes is common in oceans. Unfortunately, man-made noise from oil and gas drilling, sonar, and ships is also present.
Low frequency noise has doubled off the California coast every decade since the nineteen sixties. The main reasons are ships’ propellers(螺旋桨). They not only generate continuous low frequency sound, some propellers cavitate(形成气穴), which means they create air bubbles that collapse, creating loud popping sounds.
Whales use low frequency calls to communicate across thousands of miles of ocean. They are threatened by noise pollution because it can prevent them from contacting each other and from locating their foods. Endangered humpback and right whales, which use fibrous baleen to strain food from the water, are the most at risk.

Scientists studying right whales off Canada’s east coast have discovered that whales are sending louder calls through the water to make themselves heard. Because they invest more energy in making calls, they have less energy available for finding food and mating. Other scientists measuring whale calls against background noise pollution have discovered that right whales have lost about eighty percent of their normal communication area. This could seriously affect survival of this already threatened species.
Scientists don’t have badges and guns, but they are trying to correct the noise pollution problem. By tracking ships and marine mammals and understanding how noise travels, they are creating sound maps. They hope to get shipping lanes moved so that the noise pollution ships create will not overlap with areas most important to the whales.
