13、ommunication D. Model communicationA villager bought a pesticide. The pesticide instruction says "two consecutive days, the interval is 20 days". After seeing the villagers, they sprayed the fruit trees two times in a row and prepared to spray them in 20 days. A few days later, the fruit o

14、f his fruit trees all fell off. The problem with the description is (C).A. The manual does not fully consider the user's reading needs b. the contents of the instructions are not emphasizedThe description of the instruction is not accurateXiao bing bought a rechargeable flashlight. After each us

15、e, he habitually connected to the power supply for a long time to charge, and soon found that the battery power supply time significantly shortened. The small soldier asked for a replacement but was rejected because he didn't charge the torch correctly according to the instructions. This casedem

16、onstrates that the user should (C)A. face-to-face contact with the manufacturer to properly use the product BC. Read the product instructions carefully to ensure proper use of product D. Use the product by experience and habitSection 2 evaluation of designprelearningI. class requirementsThe quality

17、managementawareness can be evaluated according to the requirements of each stage of the design process. Can carry out simple technical experiment according to need, undertake evaluation, write test report; The design process and final product can be evaluated in various aspects according to the desi

18、gn requirements, and the design summaryreport is written. Able to evaluate other people's, existing technical products, and write a comprehensive evaluation report.2. Learning objectives1. Understand the stages and requirements of the design process and establish the awareness of quality managem
