    Some people have the feeling that nothing can be done about their poor reading ability（能力）.They feel hopeless about it.Can you learn to read better,or must you agree that nothing can be done about it?

    To be sure,people are different.You cannot expect to do everything as well as certain other people do.If all the students in a class tried out for basketball,some would be very good players,others would be very poor;and many would be in between.But even the very poor players can become much better players if they are guided in the right way,and with plenty of practice.It is the same with reading.Some seem to enjoy reading and to read well without any special help.Others find reading a slow and tiring job.In between,there are all degrees of reading ability.

    Many experiments have shown that just about every poor reader can improve his reading ability.In these experiments,the poor readers were given tests of reading ability.After some of the causes of their poor reading were discovered,they were given special instruction and practice in reading.After a few months,another test of the same kind was given.In nearly all cases,these people had raised their reading scores.

    A 9-year-old boy in Indian stopped a would-be carjacker（劫车贼）on Christmas Day from running away with his father's truck.

    Kevin Cooksey was inside the One Stop Express gas station in Kokomo buying medicine for his wife when a man jumped into the driver's seat of his truck. Cooksey had left the engine running and the door unlocked.

    "When I saw my truck door open, I was astonished, 'Oh my God, what am I going to tell my wife?'" Cooksey said.

    His son, Larry, was sitting in the back seat. "As soon as he opened the door, I got frightened," said Larry. "So I pulled out the gun and pointed it to his head."

    This was enough to make the carjacker think twice and he jumped out of the truck to try another car. Parked beside Cooksey's truck was Kyle Sparling's black Trailblazer. He too had left the engine running as he went into the store. The man got in Sparling's SUV and took off.

    "I didn't know what to think, I just kind of ran outside and watched him," said Sparling.

    As the man sped off, Cooksey told Sparling to get into his truck and the two men began to run after him. The icy winter conditions made the driving difficult, but the pair followed at a safe distance as the carjacker drove in a "Z" way. After a few miles, the carjacker knocked into the sign of a local business, American Tool and Party Rental. Cooksey and Sparling called the police to the place.

    The police put 32-year-old Ollie Dunn into prison. Sparling's car was damaged in the wheel, and the windscreen got cracked after the sign fell on it. "I was just glad he didn't knock into anybody," Sparling said. "That was my biggest fear, I think."

    Anki has introduced Cozmo, a little robot powered by an advanced artificial intelligence. Cozmo promises to be for more interactive（互动的）than any toy robot.

Cozmo, which can lie in your hand, has a “brain”—technically its CPU—that can process data amazingly fast. In addition, Cozmo has a playful personality. He's designed to react to emotions and even ask users to play with him.

    Cozmo is not the first interactive toy to reach the market nor is it the first robot toy. What sets Cozmo apart from the other “smart toys” is that it has greater play value than those toys, which can become repetitious all too quickly.

    “Every interaction with Cozmo is different, so you do not put up with repetitive play patterns and responses typically found with other preprogrammed robots,” explained Anki spokesperson Peter Nguyen. Because it has functionality that is similar to that of video games, Cozmo also can receive regular updates, which could extend its playability. Still, Anki has designed this toy to be just that: a toy. It's not an advanced computerized robot. Its software is app-based.

    Cozmo lacks the “traditional” human-like robot form factor（要素）of legs, arms, and a head. But Cozmo does have an OLED screen/face with blue eyes, which in fact were designed to help it connect with its user.

    “I'm glad my kids are already raised,” said Roger L. Kay, analyst at Endpoint Technologies Associates. “Otherwise, they might become more antisocial if their relationship with Cozmo is more satisfying than those with real people,” said Kay. “Cozmo might encourage kids to learn more about technology or even inspire them to try programming and similar studies,” said Charles King, analyst at Pund-IT.

    Yet this technology does promise to be more than a toy. “It's a pretty cool invention and might have further applications, for example in elder care,” suggested Kay.

You might think people all over the United States have Wi-Fi—wireless Internet service—and mobile phones. But there is no such service in Green Bank, West Virginia, a tiny town four hours from the U.S. capital, Washington D.C. Fewer than 150 people live in Green Bank, which has two churches, an elementary school and a public library. It is also home to the largest radio telescope in the world.

    There is a ban on Wi-Fi in Green Bank, along with anything else that can create electromagnetic(电磁的)waves. Officials say the waves could disturb the signals the telescope receives.

For many Americans, a visit to Green Bank is a little like returning to the 1950s. To get there, you must read road signs—because there is no GPS service in the town. People can connect with the Internet through telephones, but wireless service is not allowed.

    The observatory(天文台)is one of the largest employers in the area. The federal National Science Foundation(NSF) spends about ＄8.2 million a year to operate the observatory, telescope and educational center.

    Jonah Bauserman is a technician. If he supposes there is signal that is not allowed in the zone, he drives to the house where the signal is coming from and checks it. But once a week, when the device is cleaned, some banned devices are allowed near it.

    People in the town respect the work of the scientists. And they say they are happy to live without Wi-Fi and mobile phones. "You know, instead of sitting here on our phones and other devices we're out fishing and hunting and going to each other's houses." Everyone knows each other and communication is almost always face-to-face.

    Samuel Morse was born in Massachusetts USA. He started off his career as an inventor after being a painter and sculptor (雕塑家). He even earned a gold medal from the famous Adelphi Society of Arts for his first effort in sculpture, the "Dying Hercules". He became the first president of the National Academy of Design, and was made Professor of the Arts of Design in the University of the City of New York.

    Yet, this painter turned to inventing to make his fortune during a sea voyage. On this journey, Samuel Morse heard about many attempts to create usable telegraphs. He was fascinated by this problem and began to study books on physics for two years to gain more scientific knowledge. He realized that pulses (脉冲) of electrical current could carry information over wires.

    Thus the world's first working model of a telegraph was born. His signaling device was quite simple. It consisted of a transmitter (containing a battery and a key), a small buzzer (蜂鸣器) as a receiver and a pair of wires connecting the two. Samuel Morse improved it by adding a switch and a second buzzer to allow transmission (传播) in the opposite direction as well.

    On May 24, 1844 Samuel Morse sent the first electronic message between Baltimore and Washington, "Look what God has enabled us to build, and benefit by."

    Seventeen years later, the two coasts of the United States were linked by telegraph. The telegraph continued to enjoy the position of being the fastest and most reliable means of communication for almost 140 years since its invention.
