TỔNG HỢP ĐỀ THI HỌC KỲ 1 LỚP 10 NĂM HỌC 2018 – 2019 ĐỀ CHÍNH THỨC Read the following passage, and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the following questions. Forty-one years ago, Martin Cooper, an engineer for Motorola, had an idea: he wanted people to be able to carry their phones with them anywhere. In April 1973, Cooper – who is now credited as the “father of the cell phone” – became the first individual to make a call on a portable mobile device. The phone weighed more than two pounds, and it took ten hours to charge and thirty five minutes of conversation. With its 3,995 dollars price tag at first, it was hard to imagine mobile phone becomes an important part of our existence now. For the past two years, Bell, from George Washington University, has researched how mobile phones effect on culture or people’s lives. He referenced the science fiction film “Total Recall”, which was remade in 2012. It was about a kind of technology which allowed a palm to become a keyboard for a personal device on which smart surfaces let users interface with others and a wider grid. Of course, the innovation had its drawback. The film doesn't mention how such device will be powered. Bell said, however, that they could become a reality based on both nano-generators harvesting movements and bio-electronic currents. Such interfaces raise possibilities of "personal viruses" that could let individuals hack and steal specified information from each other. Those difficulties will be the change for inventing other phone generation to fix these problems. 1: What is the meaning of the word “portable”? A. Full of energy B. Hard to control C.
