It’s illegal for the police to attach a GPS unit to your car without your permission, as the U.S. Supreme Court settled in 2012. But if the police are in hot pursuit of a bank robber or other escaping criminals that threaten public safety, a GPS tracker is acceptable. But exactly how can the police GPS track a car that is moving fast?

The answer to that question comes from StarChase, a new police technology being used by a small-but growing number of law enforcement agencies. It allows the police to fire 4.5-inch glue-covered GPS bullet-like projectiles (發(fā)射體) from an air gun fixed in their police cars. If the GPS tracker makes contact with the escaping robber’s car, it’ll stick no matter how fast the vehicle is going. That way, the police will have a constant read on the car’s location and heading. Aside from simply apprehending (逮捕) criminals, it’s believed this new technology could help save lives. If the police successfully fire a GPS unit at a speeding criminal, they can pull back from a high-risk chase. Chases can be incredibly dangerous to all involved, including innocent bystanders and other drivers. Once the GPS bullet connects, there’s no need for the chase any longer.

Now, predictably, a GPS-loaded gun isn’t cheap. Police departments need to pay about $5,000 per vehicle for the technology, and individual GPS bullets cost as much as $250 each. That may sound expensive, but remember: The alternative is often thousands of dollars in property damage, and great human cost in injury and lost life. According to Star Chase, their GPS bullet system has an apprehension rate of 80% without any report of injury or property damage. If you’d like to learn more about the StarChase system, Popular Mechanics has just published a good article about it. There’s also plenty more information available at the company’s website.

A. know the car’s condition

2.The GPS bullets could help save lives mainly because

A. the bullets won’t hurt people

B. they can make the robber’s car stop

C. the police can stop the dangerous chasing

D. they have more advantages than normal bullets

3.From the text we can learn that GPS bullets

A. are useful for the police

B. are widely used in America

C. can control the rising crime rate

D. can replace the police in the future

4.In which part of a newspaper can we read the text

A.Life B.Nature C.Fashion D.Technology

At Denver there was an crowd of passengers into the coaches（車廂） on the eastbound B. & M. express. In one coach there sat a very pretty young woman dressed in elegant taste and surrounded by all the luxurious comforts of an experienced traveler. Among the newcomers were two young men, one of handsome presence with a bold, frank face expression and manner; the other a ruffled, glum-faced person, heavily built and roughly dressed. The two were handcuffed（拷上手銬） together.

As they passed down the aisle of the coach the only available seat offered was a reversed one facing the attractive young woman. Here the linked couple seated themselves. The young woman's glance fell upon them with a distant, swift disinterest; then with a lovely smile brightening her face and a tender pink tingeing（稍加染色，影響） her rounded cheeks, she held out a little gray-gloved hand. When she spoke her voice, full, sweet, and deliberate, proclaimed that its owner was accustomed to speak and be heard.

"Well, Mr. Easton, if you will make me speak first, I suppose I must. Don't you ever recognize old friends when you meet them in the West?"

The younger man aroused himself sharply at the sound of her voice, seemed to struggle with a slight embarrassment which he threw off instantly, and then clasped her fingers with his left hand.

"It's Miss Fairchild," he said, with a smile. "I'll ask you to excuse the other hand; "it's otherwise engaged just at present."

He slightly raised his right hand, bound at the wrist by the shining "bracelet" to the left one of his companion. The glad look in the girl's eyes slowly changed to a bewildered horror. The glow faded from her cheeks. Her lips parted in a vague（含糊，猶豫）, relaxing distress. Easton, with a little laugh, as if amused, was about to speak again when the other forestalled him. The glum-faced man had been watching the girl's face expression with veiled glances from his keen, shrewd eyes.

"You'll excuse me for speaking, miss, but, I see you're acquainted with（認識，熟悉） the officer here. If you'll ask him to speak a word for me when we get to the pen（圍欄，監(jiān)獄） he'll do it, and it'll make things easier for me there. He's taking me to Leavenworth prison. It's seven years for cheating."

"Oh!" said the girl, with a deep breath and returning color. "So that is what you are doing out here? An officer!"

"My dear Miss Fairchild," said Easton, calmly, "I had to do something. Money has a way of taking wings with itself, and you know it takes money to keep step with our crowd in Washington. I saw this opening（通道） in the West, and--well, an officer isn't quite as high a position as that of ambassador, but--"

"The ambassador," said the girl, warmly, "doesn't call any more. I needn't ever have done so. You ought to know that. And so now you are one of these brave Western heroes, and you ride and shoot and go into all kinds of dangers. That's different from the Washington life. You have been missed from the old crowd."

The girl's eyes, fascinated, went back, widening a little, to rest upon the glittering handcuffs.

"Don't you worry about them, miss," said the other man. "All officers handcuff themselves to their prisoners to keep them from getting away. Mr. Easton knows his business."

"Will we see you again soon in Washington?" asked the girl.

"Not soon, I think," said Easton. "My butterfly days are over, I fear."

"I love the West," said the girl irrelevantly. Her eyes were shining softly. She looked away out the car window. She began to speak truly and simply without the gloss of style and manner: "Mamma and I spent the summer in Denver. She went home a week ago because father was slightly ill. I could live and be happy in the West. I think the air here agrees with me. Money isn't everything. But people always misunderstand things and remain stupid--"

"Say, officer," shouted the glum-faced man. "This isn't quite fair. I'm needing a drink, and haven't had a smoke all day. Haven't you talked long enough? Take me in the smoker now, won't you? I'm half dead for a pipe."

The bound travelers rose to their feet, Easton with the same slow smile on his face.

"I can't deny a require for tobacco," he said, lightly. "It's the one friend of the unfortunate. Good-bye, Miss Fairchild. Duty calls, you know." He held out his hand for a farewell.

"It's too bad you are not going East," she said, reclothing herself with manner and style. "But you must go on to Leavenworth, I suppose?"

"Yes," said Easton, "I must go on to Leavenworth."

The two men sidled down the aisle into the smoker.

The two passengers in a seat near by had heard most of the conversation. Said one of them: "That officer is a good sort of man. Some of these Western fellows are all right."

"Pretty young to hold an office like that, isn't he?" asked the other.

"Young!" exclaimed the first speaker, "why--Oh! Didn't you catch on? Say--did you ever know an officer to handcuff a prisoner to his right hand?"

For a while, I wrote a “Tuesday tip” on my blog Lyonsdenmom.com. It was about easy week-night dinners, organizing parties or perhaps finding time out for friends.

About a year ago, I ran out of tips.

The truth? As a busy working mom with five busy kids, I probably do have a few tips to share. But honestly, the bar is set pretty low---on a recent day when I was walking our dog, a stranger who knew I had five kids said, “Wow! You have a dog, too?! And it even looks like you showered today!” Yes, it's true, I shower. Not every day, but most days. See, I'm telling the truth. Honestly, in this cold winter, I'm probably taking a shower more to warm up than to clean up.

Other funny truths? I'm tired. In fact, for the past year, I’ve been too tired to type up any update on our life here in Lyons Den. It's hard to arrange a career with all these kids. Although folks just believe that it must be so much easier now since all the kids are in school, I'm here to tell you, it's not. It's really not. When I get home from work, I'm often tearfully greeted by five kids and five homework folders filled with math facts, invitations, notices and artwork.

All those happy smiling faces I share on Facebook are real. We are a happy family---thank God for that! But we're not always smiling, and even in those rare best times when I can get all five kids looking at the camera, the odds would be that one of them isn’t wearing underwear, one is pinching (捏) someone behind the scenes and one is just perfectly pronouncing “Damn!” So, less perfectly-posed pictures, but more telling the truth. Even if only on Tuesday.

A. She can't get along well with her neighbors.

So many of us hold on to little complaints that may have come from an argument ，a misunderstanding，the way we were raised，or some other painful events. Stubbornly，we wait for someone else to reach out to us — believing this is the only way we can forgive or rekindle a friendship or family relationship.

A friend of mine，recently told me that she hadn't spoken to her son in almost three years. She said that she and her son had had a disagreement about his wife and that she wouldn't speak to him again unless he called first. When I suggested that she be the one to reach out，she said，“ I can't do that. He’s the one who should apologize. ” After a little gentle encouragement，however，she did de­cide to be the first one to reach out. To her amazement，her son was grateful for her willingness to call and offered an apology of his own. As is usually the case，when someone takes the chance and rea­ches out，everyone wins.

Whenever we hold on to our anger, we turn“ small stuff”問題）”into really“ big stuff” in our minds. We start to believe that our positions are more important than our happiness. They are not. If you want to be a more peaceful person you must understand that being right is almost never more important than allowing yourself to be happy. The way to be happy is to let go，and reach out. Let other people be right. This doesn't mean that you're wrong. Everything will be fine. You'll experience the peace of letting go，as well as the joy of letting others be right.

You'11 also notice that，as you reach out and let others be “right”，they will become less defen­sive and more loving toward you. They might even reach back. But，if for some reason they don't， that's okay too. You '11 have the inner satisfaction of knowing that you have done your part to create a more loving world，and certainly you'11 be more peaceful yourself.

1. The underlined word “ rekindle” in Paragraph 1 probably means “ ”.

A. recover B. develop

C. accept D. replace

2.In the author's opinion, we hold on to our anger often because we think .

A. we can turn small issues into big ones

B. our positions are higher than others

C. our own opinions matter most

D. others will be less defensive

3.The best thing to do after a quarrel is to .

A. let go of our own rights

B. realize that you are wrong.

C. expect others to give in

D. apologize to others first.

4. What is the main idea of the passage?

A. People should keep peaceful when facing small stuff.

B. Reaching out and apologizing wins one peace and happiness.

C. We should tell apart small and big stuff in our daily life.

D. It's necessary to enjoy our friendship and family relationship.
