【題目】

Calling the future

When American inventor Alexander Graham Bell invented the telephone in 1876，it was a revolution in communication. For the first time, people could talk to each other over great distances. Over the last two decades a new means of spoken communication has appeared ：the mobile phone.

The mobile phone is like a two-way radio. But the two-way radio is a limited means of communication. As soon as the users move out of range of each other's broadcast area, the signal is lost. In the 1940s, researchers experimented with the idea of using a number of radio masts（無線電桿）to pick up signals from two-way radios. A caller would always be within range of one of the masts. When he or she moved too far away from one mast, the next mast would pick up the signal. （Scientists referred to each mast's reception area as being a "cell". This is why in many countries mo-bile phones are called "cellphones".）

However，1940s, technology was just at the beginning. The "mobile phones" were huge boxes. They had to be moved by car.

The first real mobile telephone call was made in 1973 by Dr Martin Cooper. As soon as his invention was complete, he tested it by calling a rival （競爭對手）scientist to announce his success. Within a decade, mobile phones became available to the public.

They have changed the way we do a lot of things. One powerful feature is: the short message service（SMS） or text message. It's the perfect communication method for the busy modern lifestyle. The text message has changed the way we write in English. The language construction became more lax （松散的）. Traditional rules of grammar and spelling are much less important.

Over the last few years mobiles have become more and more advanced. We have seen the introduction of cameras, global positioning system and Internet access.

Alexander Graham Bell would be surprised if he could see how far the science of the telephone has developed in less than 150years. If he were around today, he might say ： " That's gr8! But I'm v busy rite now. Will call U 2nite. "

【題目】Poet William Stafford once said that we are defined more by the detours(繞行路) in life than by the narrow road toward goals. I like this image. But it was quite by accident that I discovered the deep meaning of his words.

For years we made the long drive from our home in Seattle to my parents' home in Boise in nine hours. We traveled the way most people do: the fastest, shortest, easiest road, especially when I was alone with four noisy, restless kids who hate confinement(限制) and have strong opinions about everything.

Road trips felt risky，so I would drive fast, stopping only when I had to. We would stick to the freeways and arrive tired.

But then Banner, our lamb was born. He was rejected by his mama days before our planned trip to Boise. I had two choices: leave Banner with my husband, or take him with me. My husband made the decision for me.

That is how I found myself on the road with four kids, a baby lamb and nothing but my everlasting optimism to see me through. We took the country roads out of necessity. We had to stop every hour, let Banner shake out his legs and feed him. The kids chased him and one another. They'd get back in the car breathless and energized, smelling fresh from the cold air.

We explored side roads, catching grasshoppers in waist－h(huán)igh grass. Even if we simply looked out of the car windows at baby pigs following their mother, or fish leaping out of the water, it was better than the best ride down the freeway. Here was life. And new horizons(見識)．

We eventually arrived at my parents' doorstep astonishingly fresh and full of stories.

I grew brave with the trip back home and creative with my disciplining technique. On an empty section of road, everyone started quarreling. I stopped the car, ordered all kids out and told them to meet me up ahead. I parked my car half a mile away and read my book in sweet silence.

Some road trips are by necessity fast and straight. But that trip with Banner opened our eyes to a world available to anyone adventurous enough to wander around and made me realize that a detour may uncover the best part of journey—and the best part of yourself.
