1. After Pluto(冥王星) was found in 1930, people took it as the ninth planet in our solar system(太陽系). But it isn’t like other planets. 2.It is smaller and has an strange orbit(軌道). On August 24, scientists said, “ Pluto is not a planet.”

About 2500 scientists met in Prague. At first, some of them said that there would be 12 planets in our solar system. In the end, the scientists said that only Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune are the planets in the solar system. 3. Each of these planets has its own orbit, and each of the planets is big enough to be a planet. Pluto’s orbit overlaps(交疊) Neptune’s and it is smaller than the other planets. 4.

E-book is short for electronic( 電子的) book. It is usually read on personal computers. Some
mobile phones can also be used to read e-books.
Earlier e-books were written for a specific group of readers and were about only a few subjects. With the development of the internet, knowledge and answers to a lot of questions mainly come from e-books. This is why the e-book business is increasing quickly
E-books have many advantages. First, they save time. We don’t need to go to a bookstore to buy books, besides, we can find the topic we want to know about on the Internet, and then we can quickly get many e-books on similar topics. Second, e-books save money. Some e-books cost a little money, and there are millions of e-books on the Internet that we can get for free. Third, more trees are saved because e-books don’t need to be printed(印刷) on paper. Fourth, e-books make reading more convenient. You can carry a whole library of hundreds of books with you in a small computer or any e-book reader (電子閱讀器) without worrying about their weight.
But e-books have certain disadvantages. They need a personal computer or an e-book reader and the information can be lost if its file format (文件格式) is not supported or changed in the reader’s computer.
However, e-books provide us with a new way of reading. That is good.
