5 . Like many military wives, I had to stand the long separations until my husband retired. Though I supported his chosen career, I _________ every moment away from him.

To _________ our separations, I wrote letters every day. I made up dozens of small _________ for him which I secretly put into his bag, so that he could_________ them when he was out to sea. To this day those notes are still _________ to us.

_________ in 1996 my husband retired from the Navy. But the only job _________for my husband was six-and-a-half hours away in Norfolk, Virginia.

We spent eight months_________. That was our hardest separation, perhaps because we had _________ planned to be apart again. He__________ to apply for jobs in the area where we hoped to live. We expected we would soon be able to be __________ again.

One day Louie called me with the good __________. He found a job in southwest Virginia. We were excited ! There was only one small__________. Louie would have to live in a camper(露营车),__________ our daughters and I lived in a little house an-hour-and-a-half away. My daughters were __________enough to take care of themselves, so I left them and stayed with Louie.

Louie and I spent a __________ three-and-a-half weeks together. One morning after he left for work, I sat __________ in the camper trying to remember any possession that was as priceless as the __________we stayed together. I couldn’t __________a single thing. Then all of us moved into that camper and lived there for a year. It was pure joy! I’ve learned in that year that the greatest __________ I have is the time I ’ve spent with the ones I love.

8 . When Matty Sallin was working on a degree in art and technology at New York University, he got an interesting assignment in electronics class: Create something for the household. He decided to create an alarm clock.

“Everybody has to deal with these every day, and they are extremely unpleasant!" he says. He asked different people what they’d like to wake up to instead of a clanging, noisy alarm. A lot of them said, "The smell of bacon.”

So Sallin and two classmates invented a new kind of alarm clock: a wooden box with a pig face and a digital clock that uses the smell of cooking bacon rather than sound to wake someone up. He explains, “There’s no danger of burning, because it uses halogen light bulbs（卤素灯泡）instead of a flame for cooking and turns off automatically after ten minutes.”

Just a few easy steps are required to set the “alarm.”

“What you do is to put a couple of frozen pieces of bacon in the night before,” says Sallin. “If you set the alarm for 8:00, it will turn on at 7:50 and slow cook for ten minutes under the halogen bulbs,” he says. Then the bulbs turn off and a fan blows the smell out through the pig nose.

“So instead of an alarm or a beep or a radio, you smell yourself awake,” says Sallin. “Then you can open the door on the side and pull the bacon out and eat it.”

When Sallin was a kid, he spent a lot of time making drawings of inventions. “I wanted to make an elevator in my back yard and a special tree house,” he says. “But I never really thought I’d be called an inventor!”

9 . It was realized that if an apparatus (装置) could be designed to send out radio waves all the time and record the echoes from any approaching airplanes, it would be a wonderful method of defense in the last war.

Scientists set about solving the problem and radar was invented. An apparatus was made which sent out waves in pulses, and the presence of a distant airplane was shown on the screen (this is what we have in a television set). In this way radar station could detect the approach of enemy aircraft.

After the war radar was put to peaceful uses. It is now installed at airports to guide airplanes down safely in fog. It is fitted to ships so that they are warned of obstructions (障碍物) ahead, such as icebergs. It guides ships into port. It provided airplanes and ships with a magic eye, with which they can see far into the distance, in the dark or in fog.

10 . My brother and I often fight with each other over small things. One day our father said to us, “Tomorrow we will take part in the Ray Home Sports Day. Both of you must go with me. Perhaps you can learn something from those children.” My brother laughed, “Dad, Ray is a home for physically disabled children. What can we learn from them?”

“You will see,” our father said.

Our father works as a volunteer at Ray. The children there have problems with their hands, speech, walking or hearing. Every day, he spends hours helping them to move or exercise their legs or arms.

The following day, he took us to Ray Home. When we got there, we found a nice place to sit down. Finally, the sports began. There was a 50-meter race to see who could run fastest. All the runners were physically disabled. As the race started, all the children moved as fast as they could. Just then, one of the girls fell over and hurt her leg. She began to cry at the top of her voice.

All the children stopped to help the poor girl. Then they all held hands and finished the race together. My brother and I were surprised to see this: the children weren’t interested in winning the race－they were more interested in helping each other to finish the race.
