Letter in the Centerville College News
The administration has plans to acquire a new sculpture for campus. We should all oppose this plan. The university’s poor financial condition led it to increase the price for campus housing and tuition by 15% this past year. Surely then it is no financial position to purchase such an expensive sculpture. Moreover, just look at the sculpture: several 60-foot long steel plates, jutting out of the earth at odd angles! It’s so large, it’ll take up all the green space in front of the campus center! This is public space that should be reserved for students to use.

Task3：
Groupthink
阅读材料
Groupthink
One process by which groups may make bad or irrational decisions is known as groupthink. Individual members of a group attempt to conform their opinions to what they believe to be the group consensus even though the result may be negative. There are many reasons why groupthink happens. These include the desire to be liked, fear of losing a job, or even not wanting to be the one employee delaying a decision that seems inevitable. These kinds of implicit pressures to conform lead group members to ultimately make decisions that each, by himself or herself, might normally not make.
