de que está hecho
Here's your answer. Let's break it down:"Te alegras de algo" = You are happy about something"que haya hecho un amigo" = that a friend may have done"esta semana" = This weekFull sentence: You are happy about something that a friend may have done this week.It's important to notice the subjunctive tense of "haber" (haya.) The subjunctive tense is used when there is uncertainty about whether an action was or will be completed. In this case, your friend may have done something to make you happy but they may not have. If you had said "que ha hecho un amigo" the meaning would change to something your friend definitely did this week.Good luck on your Spanish final!
