Do you know some great inventors and their inventions?

What factors (因素) are needed for their success?

Well, good timing for a start. You can have a great idea which the public simply doesn’t want ... yet. The Italian Giovanni Caselli invented the first fax(传真)machine in the 1860s. Although the machine was excellent, his invention quickly died a commercial(商业的) death. It was not until the 1980s that the fax became very common in every office... too late for Giovanni Caselli.

Money also helps. The Frenchman Denis Papin (1647-1712) had the idea for a steam engine (蒸汽机)almost a hundred years before the better-remembered Scotsman James Watt was even born... but he never had enough money to build one.

You also need to be patient (it took scientists nearly eighty years to develop a light bulb which actually worked)... but not too patient. In the 1870s, Elisha Gray, a professional inventor from Chicago, developed plans for a telephone. Gray saw it as no more than “a beautiful toy”. However, when he finally sent details of his invention to the Patent Office(专利局) in February, 1876, it was too late. Almost the same invention had arrived two hours earlier... and the young man who sent it, Alexander Graham Bell, will always be remembered as the inventor of the telephone.

Of course what you really need is a great idea—but if you haven’t got one, a walk in the country and careful look at nature can help. The Swiss scientist, George de Mestral, had the idea for Velcro(魔术贴)when he found his clothes covered in sticky seed pods after a walk in the country. During a similar walk in the French countryside some 250 years earlier, Rene Antoine Ferchault de Reaumur had the idea that paper could be made from wood when he found an abandoned wasps’ nest(蜂巢).

You also need good commercial sense. Willy Higinbotham was a scientist doing nuclear(核能的) research in the Brookhaven National Laboratory in Upton, USA. In 1958, the public were invited to an exhibition in the Laboratory to see their work, but both parents and children were more interested in a tennis video game on the screen. Soon hundreds of people were ignoring the other exhibits to play the first ever computer game—made from a simple laboratory instrument called an “oscilloscope”. Higinbotham, however, never made money from his invention: he thought people were only interested in the game because the other exhibits were so boring!

Nowadays, many teens are badly addicted to using phones. It probably won’t surprise you that teens are texting more than ever before.

Instead of sleeping, Kenny Alarcon, 16, often texts with his friends through the night. Frances Garcia, a high school senior, sends and receives about 1000 texts each day. Both Frances and Kenny wake up several times during the night to text. Kenny even sleeps with his phone under his pillow.

Dr.Elizabeth Dowdell, a professor at Villanova University in Pennsylvania, says that it’s common for teens to be interrupted by texts while sleeping. “If they often lose sleep,” Dr.Dowdell says, “teens may become angry, or depressed. A lack of sleep can lead to weight gain and even obesity because many people turn to junk food for quick energy when they are tired.”

Some experts are worried about how texting is affecting teenagers’ lives. One concern is that students might not learn correct grammar and spelling if most of the writing they do is made up of text messages. Some people also worry that teens don’t spend enough time talking with others face-to-face, which could be hurting their relationships with friends and family. Moreover, all that texting takes away hours that could be spent studying, exercising, taking up a hobby, or just relaxing.

According to Dr. Dowdell, teens need to learn that they can and should turn off their phones sometimes. She had Kenny and Frances do an experiment. These were the rules: No phone for 48 hours. No computer or Internet either, unless it was for schoolwork.

After 48 phone-free hours, Kenny and Frances were interviewed. “Wow, it was pure torture(折磨),” Kenny joked. Kenny missed his friends, and he was sad at times. But he also felt relief from the constant texting. He spent time reading books and talking with his family, which he really enjoyed. Frances had an even happier result. “I loved it!” she said, “I was going to the gym and hanging out with friends and playing basketball. I had a wonderful experience.” Frances decided to continue the experiment for a while. “I think I’ll be so much smarter and healthier,” she explained, “everybody in the world should try it.”

2.What is Paragraph 4 mainly about?
