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!

18、Tsunami(海啸)is a natural disaster，which is a Japanese word that means “sea wave”．A tsunami is a huge sea wave that forms mainly in the Pacific Ocean area. People die and property is destroyed when a tsunami hits land. What causes these dangerous sea waves？Sometimes，tsunamis are caused when earthquakes take place underwater. Then，water begins to move up and down from the top of the ocean right down to the bottom. Waves begin to form，and each wave is called a tsunami.

Recently, our class had a discussion about whether students should learn on the Internet.
Some students support it. They think online learning is much more convenient and the Internet is filled with useful resources. What’s more, learners have freedom to decide what and when to learn. However, some students don’t welcome it. Although, they think there’s a lot of information on the Internet. Some information isn’t true. Also, spending a long time searching information online is bad for their eyes. In my opinion, every coin has two ideas. I think it’s better to use both the traditional way of learning and online learning. Students should use the Internet properly.
