“Get your hands off me, I have been stolen,” the laptop, a portable computer, shouted. That is a new solution to laptop computer theft (the crime of stealing): a program that lets owners give their property a voice when it has been taken.
The program allows users to display alerts (warning) on the missing computer’s screen and even to set a spoken message. Tracking software for stolen laptops has been on the market for some time, but this is thought to be the first that allows owners to give the thief a piece of their mind.
Owners must report their laptop missing by visiting a website, which sends a message to the model: a red and yellow “lost or stolen” sign appears on its screen when it is started. Under the latest version of the software, users can also send a spoken message.
The message can be set to reappear every 30 seconds, no matter how many times the thief closes it. “One customer sent a message saying, ‘You are being tracked. I am right at your door’,” said Carrie Hafeman, chief executive of the company which produces the program, Retriever.
In the latest version, people can add a spoken message. For example, the laptop’s speakers will say: “Help, this laptop is reported lost or stolen. If you are not my owner, report me now.”
The Retriever software package, which costs $29.95 but has a free trial period, has the functions of many security software programs. Owners can remotely (远程地) switch to an alternative (可替换的) password immediately if they fear that the thief has also got hold of the access (进入, 使用) details.
If a thief accesses the Internet with the stolen laptop, Retriever will collect information on the Internet service provider in use, so that the police can be alerted to its location.
Thousands of laptops are stolen every year from homes and offices, but with the use of laptops increasing, the number stolen while their owners are out and about has been rising sharply.
Other security software allows users to erase data remotely or lock down the computer.The underlined expression “to give the thief a piece of their mind” in Paragraph 2 can be understood as “_______”.
| A．to give the thief an alert mind |
| B．to express the owners’ anger to the thief |
| C．to remind the thief of his conscience (良心) |
| D．to make the thief give up his mind |
Different from other security software, Retriever can _______.
| A．record the stealing process |
| B．help recognize the lost laptop |
| C．lock down the computer remotely |
| D．send a spoken message |
One function of the program is that it allows the owner to _______ at a distance.
| A．change some access details for switching on the laptop |
| B．turn on the laptop by using the original password |
| C．operate the laptop by means of an alternative password |
| D．erase the information kept in the stolen laptop |
Which of the following can best sum up the main idea of the passage?
| A．With no Retriever, thousands of laptops are stolen every year. |
| B．A new software provides a means to reduce laptop theft. |
| C．Retriever has helped to find thieves and lost computers. |
| D．A new program offers a communication platform with the thief. |

| C．the program | D．the laptop |
I decided to have dinner in the hotel, for I arrived late one night on a business trip. As I was finishing my meal, an elderly couple came in to dine. They were holding hands and had lovely smiles on their faces. They sat three tables from me. I was amazed at the love they showed for each other. It seemed to strike home all the more, because it was shortly after ending a 20-year marriage and I still had pain in my heart.
My waiter was also their waiter. As I paid my bill, I inquired as to what their bill was. He informed me, and I gave him $40 to pay their bill. He asked if I knew them and I told him "No, I just wanted to repay them for the love that they were showing to each other," and then I departed.
The next day I entered the restaurant to dine before my departure. After I had been seated, the waiter who served me the night before told me that the strangest thing happened after I left the restaurant.
When the elderly couple went to pay for their meal, they were informed that it had been paid. When they inquired who had done this, the hostess told them they had no idea who I was, just retelling what I said.
The couple were amazed. They looked around, asked for the bill of two young couples who were seated together, paid their bill and departed, saying "Love begets(产生) Love" to the amazement of the hostess and waiter.
I smiled and said "That's nice," and proceeded to order my meal.
About 45 minutes later, I finished my meal and was about to head out, but my waiter was nowhere to be found. I waited and waited and finally walked over to the hostess stand and explained that I needed to pay for my meal and hurry to the airport. She smiled and explained that I would not have to pay for my meal, because both the waiter and she felt compelled to pay my bill due to the joy that was brought to the faces of the elderly couple and the amazement of the young couples.
When I told her that they didn't have to do that, she said with a smile "Love begets Love."The writer’s purpose of writing the passage is to .
| A．suggest love never dies |
| B．share an interesting experience |
| C．encourage us to help people in need |
| D．prove a show of love really makes a difference |
Why did the elderly couple pay the bill of the two young couples?
| A．Because they were always ready to help poor people. |
| B．Because they were happy to pass the love they gained. |
| C．Because they invited the young people to the meal. |

Don't you just love ice skating every winter? I am sure, that since winter is approaching, your skates are set to come out, just waiting to be used. Impress your friends with your new trick on how to ice -skate backwards with the help of these tips. Skating backwards on ice is a bit difficult but once you master the basic, there' s nothing like it. Follow the steps given below and you will be able to skate backwards in no time.
Stand Straight
The first thing that you need to do is, stand straight. If you feel that you are falling backwards, then just put your chin up and slightly bend your knees. Don't worry; this happens to all.
Confidence is What You Need
The most important step while learning how to skate backwards, is having enough confidence in yourself and in what you are doing. How can you achieve this? By practice. Just practice rolling backwards down a gentle slop every single day or just by pushing off from a wall or something of that sort. But before you do that, make sure that the place where you are practicing is free from any kind of debris （碎片） because otherwise, you could end up in the hospital due to some accident. While going backwards, just get used to the feeling of moving backwards. One of the important ice skating tips and techniques is that if you feel that you are losing your balance, then scissor （做剪式运动） your skates. Keep practicing this till you are confident about it.
Maintain Speed
Confident now? Great! Now the next step is to maintain your speed. While rolling in a straight line with one skate, with the other try sculling （滑浆）, that is, keep pushing yourself backwards with an outwards stroke （滑动）. Now bring the skate which you were using to scull, and then again, repeat the same process. Make sure that you put most of your weight on the skate which is moving straight and not the one with which you are sculling. Now, try the same thing using the other foot. Again keep doing this till you are confident enough.
Increase Your Speed Now
Once you are confident that you can scull with either foot, the next thing that you have to do is increase your speed. Try some of your own tricks now. Scull with either foot or with both at the same time.
Scull and Be Aware
While you keep one foot straight, keep sculling with the other. You can do that simultaneously （同时，一起） with both feet. Concentrate on what you are doing but don't get so involved that you don't see where you are going. If you are not watching your back, you might just bang against something or someone. According to the text confidence comes from ______ .
| A．constant exercise | B．strict coaches |

One of my wonderful memories is about a Christmas gift. Unlike other gifts, it came without wrap(包装).
On September 11th. 1958. Mum gave birth to Richard. After she brought him home from hospital, she put him in my lap, saying. "I promised you a gift, and here it is. " What an honor! I turned four a month earlier and none of my friends had such a baby doll of their own. I played with it day and night. I sang to it. I told it stories. 1 told it over and over how much I loved it!
One morning, however, I found its bed empty. My doll was gone! I cried for it. Mum wept and told me that the poor little thing had been sent to a hospital. It had a fever. For several days, I heard Mum and Dad whispering such words as "hopeless", "pitiful", and "dying", which sounded ominous.
Christmas was coming. "Don’t expect any presents this year." Dad said, pointing at the socks I hung in the living room. "If your baby brother lives, that'll be Christmas enough.” As he spoke, his eyes filled with tears. I'd never seen him cry before.
The phone rang early on Christmas morning. Dad jumped out of bed to answer it. From my bedroom I heard him say. "What? He's all right?" He hung up and shouted upstairs. " The hospital said we can bring Richard home!"
"Thank God.'" I heard Mum cry.
From the upstairs window, I watched my parents rush out to the car. I had never seen them happy. And I was also full of joy. What a wonderful day! My baby doll would be home. I downstairs. My sacks still hung there flat. But I knew they were not empty; they were filled with love!What happened to the author on September 11 1958 ?

Most people know precious gemstones (宝石) by their appearances. An emerald flashes deep green, a ruby seems to hold a red fire inside, and a diamond shines like a star. It’s more difficult to tell where the gem was mined, since a diamond from Australia or Arkansas may appear the same to one from the Democratic Republic of the Congo. However, recently, a team of scientists has found a way to identify a gemstone’s origin.
Beneath the surface of a gemstone, on the tiny level of atoms and molecules, lie clues to its origin. At this year’s meeting of the Geological Society of America in Minneapolis, Catherine McManus reported on a technique that uses lasers to clarify these clues and identify a stone’s homeland. McManus directs scientific research at Materialytics, in Killeen, Texas. The company is developing the technique. “With enough data, we could identify which country, which mining place, even the individual mine a gemstone comes from,” McManus told Science News.
Some gemstones, including many diamonds, come from war-torn countries. Sales of those “blood minerals” may encourage violent civil wars where innocent people are injured or killed. In an effort to reduce the trade in blood minerals, the U.S. government passed law in July 2010 that requires companies that sell gemstones to determine the origins of their stones.
To figure out where gemstones come from, McManus and her team focus a powerful laser on a small sample of the gemstone. The technique is called laser-induced breakdown spectroscopy. Just as heat can turn ice into water or water into steam, energy from the laser changes the state of matter of the stone. The laser changes a miniscule part of the gemstone into plasma, a gas state of matter in which tiny particles called electrons separate from atoms.
The plasma, which is superhot, produces a light pattern. (The science of analyzing this kind of light pattern is called spectroscopy.) Different elements produce different patterns, but McManus and her team say that gemstones from the same area produce similar patterns. Materialytics has already collected patterns from thousands of gemstones, including more than 200 from diamonds. They can compare the light pattern from an unknown gemstone to patterns they do know and look for a match. The light pattern acts like a signature, telling the researchers the origin of the gemstone.
In a small test, the laser technique correctly identified the origins of 95 out of every 100 diamonds. For gemstones like emeralds and rubies, the technique proved successful for 98 out of every 100 stones. The scientists need to collect and analyze more samples, including those from war-torn countries, before the tool is ready for commercial use.
Scientists like Barbara Dutrow, a mineralogist from Louisiana State University in Baton Rouge, find the technique exciting. “This is a basic new tool that could provide a better fingerprint of a material from a particular locality,” she told Science News. We learn from Paragraph 1 that __________________.
| A．an emerald and a ruby are names of diamonds. |

| B．Gemstones from the same area produce similar light patterns. |
| C．Laser can changes a miniscule part of the gemstone into plasma. |
| D．Materialytics has already collected patterns from thousands of gemstones. |

| B．People can use the new tool to find more gemstones. |
| C．It can significantly reduce the gemstones trade in blood minerals. |
