The answer to the question of "magic e-book bag" in the sixth grade of primary school

Read the magic e-book bag and answer the questions:

When it comes to schoolbags, no one will be unmoved, because it has accompanied us through the best years of our lives. Unfortunately, at present, children have a fear of schoolbags. It is said that some people have weighed the schoolbags of middle school students, and most of them are between 10 kg and 20 kg. The heavy schoolbag bent the students' backs and hurt their parents' hearts.

Is there a solution to the problem? Don't worry, in the e-era, the e-book bag that has come out will make parents frown. It is understood that People's Education Publishing House is debugging an e-book bag. This kind of schoolbag is equivalent to the size of 16 folio, with a thickness of about 1 cm and a weight of only 700g, and IMB memory. The first batch of 200 electronic schoolbags, divided into four classes, will be tried out in Beijing, Shanghai, Dalian and Shenzhen.

If these schoolbags are exquisite, you can put them in your pocket. Although simple, it can be used from primary school to university graduation, and it can be used for graduate school and doctoral studies for decades. All homework can be done in this book. If you want to update the content, just take a disk and go in. In this way, there will never be a mountain of textbooks and exercise books in class, even pens, pencils and other stationery, and an e-book bag in 16 format will replace all this.

In Singapore, e-books are developing faster. It is actually an electronic device that stores, records and reads information and materials. There are several electronic card slots on it. Students can insert textbook cards, homework cards, dictionary cards, etc. They can also connect to the Internet to send and receive e-mails and exchange learning experiences with students anywhere in the world. Obviously, the emergence of electronic schoolbags indicates a global educational revolution.

But promoting this product will not happen overnight. Strictly speaking, technically, it is simpler than PDA, and it is not a complicated product. Its only drawback is that it is too expensive. Now its price is 1.500 to 1.600 yuan, which is equivalent to a student's book fee for three years in high school. It is still difficult to promote it throughout the country. It is not difficult to reduce its price below 65,438+0,000 yuan. Didn't the mobile phone cost 10 thousand or 20 thousand when it first came out? Now it's only 1000 yuan.

On the other hand, traditional paper textbooks are not conducive to environmental protection. There are more than 320 million students in our country. If each student has an average of 20 textbooks, it will reach 65.438+0.28 billion copies every year, and the exercise books used by students will reach 24 billion copies, and the total number of textbooks and exercise books will reach 36 billion. What an amazing number this is! How many forests are cut down every year for this purpose. Obviously, the emergence of electronic schoolbags will change this situation, leaving more forests for us and more green for future generations.

Although the weight is small, it is as heavy as a thousand pounds. Although the e-book bag is small, its influence cannot be ignored. It has not only brought great changes to China's educational methods, but also exerted great influence on many aspects of society.
