Do you think nano is amazing? Tell me why.

Nanometer is one billionth of 1 meter. Since the invention of scanning tunneling microscope, the frontier science with the scale of 0. 1 nm ~ 100 nm has been born in the world, which is nanotechnology. Nanotechnology reveals the visible world of atoms and molecules with unprecedented resolution, and its ultimate goal is to construct products with specific functions directly from atoms and molecules. Since 1990s, nanotechnology has developed rapidly, and new terms and concepts have emerged, such as nanoelectronics, nanomaterials, nanomechanics, nanobiology and so on. Scientists predict that the arrival of the nano-era is not far away, and its application will surpass the computer industry in the future and become the core of the future information age. . As Qian Xuesen, a famous scientist in China, said, nanotechnology will bring a technological revolution, which will lead to another industrial revolution in 2 1 century. Scientists have outlined the blueprint for us in a few years: nano-electronics will make quantum components replace microelectronic devices, and giant computers will be put into pockets; Through nanocrystallization, fragile ceramics can become tough and become important materials; There will also be machines and even robots below 1 micron in the world; Nanotechnology can also provide new methods and means for drug delivery, such as gene mapping. Micron technology, represented by microelectronics technology, has had and is having a far-reaching impact on the world. Nanometer, which goes deeper into the microscopic world than micron, will enable human beings to further grasp the laws of matter and transform the weapons of the microscopic world. At present! Nanotechnology has been widely used in optics, medicine, semiconductors, information and communication, and its annual turnover can reach 50 billion dollars. It is predicted that by 20 10, the market capacity of nanotechnology will reach1440 billion US dollars. Nanotechnology, whose details are magical and little known, will completely change the current industrial structure and give birth to huge business opportunities. 1. Nanometer is a unit, and nanotechnology is in-. (2 points) 2. The most remarkable thing about nanotechnology is the first stage-the natural stage. (2 points) 3 The underlined sentences in the fifth paragraph are intended to illustrate. (3 points) 4. Can you remove the word "will" from the sentence "look at the magic and see that nanotechnology will completely change the current industrial structure and breed huge business opportunities"? Why? (3 points) 5. The following are some understandings around the content of this article, and the correct one is (). (Multiple choices) (4 points) A. The rapid development of nanotechnology will eventually break through the future information age, thus realizing another industrial revolution in the history of human civilization development in 2 1 century. B. nanotechnology is more advanced than micron technology. C. nanotechnology is widely used now, and its market turnover is as high as $50 billion. This shows that the era of nanotechnology has arrived. D today's truth may be reduced to absurdity when nanotechnology plays its full role in the future, which requires us to have a liberated brain and be ready to meet new things and accept new ideas at any time.

1, and nanometer is the unit of length. Born after the invention of scanning tunneling microscope. 2. This is paragraph 5. 3. It shows that nanometer is widely used. 4. No, it will mean soon. If it is removed, it will mean already. 5、D
