浙江省金华市义乌市七校联考2024-2025学年九年级上学期10月月考英语试题
Have you ever unlocked a shared bike? Have you ever ordered a meal online? Have you ever enjoyed watching the short- form videos on the Internet? Well, if no one had invented the cell phone, none of these would have been possible.
Luckily, someone did invent the cell phone. That person is Martin Cooper, and he did that 51 years ago, in 1973.
Cooper used to work for Motorola. In the 1970s, the company was competing with AT&. T, a larger company, to make a cell phone system. Cooper didn't think Motorola's product was good enough. He didn't like AT&T's idea of a car phone, either. The man had a new idea. He wanted to make it possible for people to talk on their phones anywhere.
It took Cooper and his team 90 days to design the world's first cell phone. The product was called Dyna TAC. People could talk on it for 25minutes before its battery(电池)died. The phone's short battery life wasn't a big problem, Cooper once joked. Why? Well, the phone was too heavy(1,100 grams)to hold in hand for more than 25minutes!
On 3 April, 1973, Cooper made the world's first public cell phone call. He called Joel Engel, an AT&T manager. Cooper told Engel, "I'm calling you on a cell phone. It's a real, handheld cell phone." On the other end of the line, there was only silence.
Cell phones have changed a lot since that first call. They're much smaller and can do many more things. Cooper, now 96, is surprised at the progress.
But the man has also kept thinking about life in the future. "Keep learning all your life," he says, "or you'll lose the ability to learn-- that would be terrible!"

An Unusual School Brings the Outside In Pupils in Madrid, Spain have helped to design a school that is connected to nature. Reggio School is a six-storey building featuring a drawbridge entrance, walls made from mashed cork (软木泥) which provide a home for insects and an indoor rainforest. The school was designed by Andris Jaque, who asked pupils for bright ideas. "I want it to be as colorful and playful as a child's imagination." Andres said. ▲ Starting in the 2023-24 school year, students in a northern Indiana school district (学区) will only be allowed to use clear bags at school. And each student will get one clear bag for free. This measure (措施) has been taken to improve safety in schools. It may help stop certain students from bringing dangerous objects such as guns with them to school. The ‘Dazing Zone' at a Chinese University Guangdong University of Finance and Economics has set up six "dazing zones (发呆区)" in its library for students to relax and get inspiration (灵感). Such zones are equipped with desks. chairs and plants, where students can overlook beautiful scenery, think, communicate, eat and rest. "The zones are designed to guide students over the best way to refresh themselves other than to escape from important tasks or projects." says Wang Zhongsheng, the head of the library. |
