Patience is of great important in our daily life. Once I waited a bus to come at a stop. 30 minutes past, but no bus came. Both upset and annoyed, I decided to walk on feet. But no sooner had I left when the bus arrived. I thought if I had waited for one more minute, I would have caught it. If I chose to take a next bus, I would have to wait for other 30 minutes. Only then do I realize my problem. Being impatient will possibly waste all the effort that we have put it in. Now whenever I am close to lose my patience, I’ll think of this experience

I teach geography at UNLV three times per week. Last Monday, at the beginning of class, I cheerfully asked my students how their weekend had been. One young man said that his weekend had not been so good. He had his wisdom teeth removed. The young man then asked me why I always seemed to be so cheerful. “I choose to be cheerful.” I said. Then I told them a story.

In addition to teaching here at UNLV, I also teach out at the community college in Henderson, 17 miles down the freeway from where I live. One day I drove those 17 miles to Henderson. I exited the freeway and turned onto College Drive. I only had to drive another quarter mile down the road to the college. But just then my car died and wouldn’t start again. So I left my car there and marched down the road to the college.

As soon as I got there I called AAA (美国汽车协会)and arranged for a tow truck (拖车) to meet me at my car after class. The secretary in the office asked me what had happened. “This is my lucky day.” I replied, smiling.

“Your car breaks down and today is your lucky day?” She was puzzled. “What do you mean?”

“My car could have broken down anywhere along the freeway but it didn’t.” I replied, “Instead, it broke down in the perfect place: off the freeway, within walking distance from here. I’m still able to teach my class, and I’ve been able to arrange for the tow truck to meet me after class.” The secretary’s eyes opened wide, and then she smiled. I smiled back and headed for class. So ended my story.

I scanned the sixty faces in my class at UNLV. Despite the early hour, no one seemed to be asleep. Somehow, my story had touched them. Or maybe it wasn’t the story at all. In fact, it had all started with a student’s observation that I was cheerful. An Indian wise man once said, “Who you are speaks louder to me than anything you can say.” I suppose it must be so.

2. What happened to the author on his way to the community college?

C. He covered the last quarter mile on foot.

D. He drove off the freeway at a wrong exit.

A. His story is not convincing

B. He shouldn’t have told the story

B. You are what you choose.

C. Behind bad luck comes good luck.

D. A good beginning makes a good ending.

A ground-based system that uses much stronger signals than GPS can find your location in cities and indoors. It is a new positioning system that could compete with GPS to make sure you never lose your directions again.

Instead of satellites, Locata uses ground-based equipment to send a radio signal over a localized area that is a million times stronger on arrival than GPS. It can work indoors as well as outdoors, and the makers claim that the receivers can be shrunk(缩小) to fit inside a regular cell phone. Even the US armies, which invented GPS technology, signed a file last month agreeing to a test of Locata at the White Sands Missile Range in New Mexico.

“This is one of the most important technology developments for the future of the positioning industry,” says Nunzio Gambale, CEO and co-founder of the firm Locata, based in Griffith, Australia.

As for the Locata’s correctness, Christopher Morin of the US Air Force tested it recently at White Sands, and it worked to within 18cm along any axis(轴). Morin said it should be possible to get the exactitude down to 5cm.

The tests were performed in an open desert where GPS also worked beautifully, but its signal was weak—like a car headlight from 20,000 kilometers away—and easily cut off by solid objects(实心的物体). Locata’s signal was far stronger, though not guaranteed to work in a complex urban environment, said David, speaker of the UK’ s General Lighthouse Authorities.

Locata’s technology will face competition in the race to transform indoor navigation. But it could shine in specific areas, Gambale said. Robots with Locata could easily navigate inside buildings without the complex optical(视觉的) systems they need at the moment. And the process that handles correct location data could not only guide you around a mall, railway station or airport, but also take you to the exact shelf in a shop for the product you want. It would be small and cheap enough for smart phones and it should be available within five years—a similar path to the one GPS took on its way towards the world, he said.

1.The passage is written mainly to ______.

A. encourage people to buy the Locata

B. tell us the disadvantages of the GPS

C. introduce a new positioning system Locata

D. tell us that Locata will replace GPS one day

2.Which of the following is NOT true about Locata?

A. Without the help of the satellites, Locata can tell you where you are.

B. Locata will be popular with most people even including the US armies.

C. Locata has a better signal than GPS in some bad environments.

D. In five years, Locata will take the place of GPS.

3.According to the passage, Gambale______.

A. did the experiment at White Sands last month

B. believed the Locata would help to develop smart robots’ creation

C. doubted whether Locata can work in a complex environment or not

D. was worried about the competition the Locata faced

4.Which of the following can replace the underlined word “exactitude” in Paragraph 4?

A. Accuracy. B. Speed.

C. Determination D. Length

5.What can we know from the passage?

A. Locata is as small as a cell phone.

B. GPS is the most practical position system at present.

C. Locata will tell you how to get what you want in the future.

D. Locata will enter our lives through the cell phone, just like GPS.
