1、新高考下的课前十分钟设计学案- 高三新高考。课前十分钟:六分钟是最新时文原创阅读(练习是提问式),四分 钟小说后的读后续写练习(微写作放在课后,讲义提前发下去)。安排理由:新高考 的阅读是关键,阅读速度是第一位。设题需要仅仅围绕高考命题特点和选材特点。 时文:Aug. 25, 2020 Economist They might appear cutesy, but a pair of robots that turned up recently at the Ford Motor Companys Van Dyke Transmission Plant, in Detroit, are pra
2、ctical working machines. They may, indeed, point to the future of automation. Putting robots into factories is hardly a new ideasome 2.4m of them are already at work in plants around the world. But most of these are little more than giant arms. Those few that have the mobility to manage tasks like d
3、elivering components do so by scooting along on wheels. The new devices at Van Dyke are rather different sorts of beasts. This pair of bright-yellow quadrupeds (/kwdrpd/四足动物) look a bit like dogs, prompting one to be nicknamed Fluffy and the other Spot. The pair are not there to amuse the factorys h
4、uman workers, though, but rather to perform an important task that Ford hopes will save it a ton of money. With laser scanners mounted on their backs, Fluffy and Spot can scamper around the 200,000 square-metre plant collecting data. Those data will be employed to build a detailed computer model of
5、the entire manufacturing operation. This sort of model is called a digital twin, and Fords engineers will use it to work out how to rearrange the production line to produce a new gearbox. Over the years, factory plans get out of date as things are moved around and new equipment is brought in. Survey
6、ing the transmission plant by hand would take weeks and cost some $300,000. Ford reckons that Fluffy and Spot, which can both climb stairs and crawl into hard-to-reach areas, will cut the time required by half and complete the job for “a fraction of the cost”. Although Ford is leasing the robots, Bo
7、ston Dynamics has now put them on sale for $75,000 a pop. At that price they would soon pay for themselves doing tasks like the one being undertaken in Van Dyke. Problems remain, and improvements are needed. “But once we get there, we are going to have millions of walking robots in human environment
8、s,” says Jonathan Hurst, co-founder of Agility Robotics, a firm based in Albany, Oregon. At present, Digit costs $250,000. But it is early days. As more walking robots are put to work their development will accelerate and their production volumes increase, bringing the cost of a machine like Digit d
9、own to the tens of thousands of dollars. Questions: 1. What are the functions of the new robots? 2. How and why does Ford use the new robots? Just give some examples. 3. What is Jonathan Hursts attitude towards the future of the new robots? 4. Please give a title to the passage. 读后续写阅读:读后续写阅读: 小说:I
