Letter: the campus newspaper suggests that the computer maintenance service extend to 9 pm at night
Reason 1: lots of students need to fix their computers immediately to continue their urgent projects
Reason 2: student staff can learn more practical skills through this.
【学生态度】：The woman agrees with it.
1. The woman’s computer broke down one night, and she couldn’t get it fixed that night, so she couldn’t finish her projects on time.
2. Students in the helpdesk are mostly from computer-related majors, and they can practice the knowledge they learn from textbooks in this job.
Question: Explain the woman’s opinion and why she holds that opinion.
Recruitment: social animals release chemical message to call other members of the same species to complete a task that couldn’t be done by the animal alone.
The lecture explains how ants move the food to their nest. Once an ant finds a large food, the ant will go back to its nest leaving a special kind of chemical along the trail. Other members in the nest would trace the food with the chemical and reach to the large food. During this process, they would continue leaving the same chemical message along the trail attracting more ants to come and help. Finally, the ants move the large food back to the nest together.
The lecture talks about two internal constraints that make the business fail.
1. Lack of physical resources. The service hall doesn’t have enough devices for a particular service, and salespersons couldn’t handle the devices quite well. So, customers have to wait in line and have a bad impression to the company.
2. Lack of employee training. In a grocery store, a new salesperson is not quite familiar with the location of different goods, and couldn’t guide the customers to the right place. Most customers feel disappointed and leave.
