Student Plays Should Be Free for Everyone
Thanks to our superb theater program here at the university, we are fortunate to be able to see many plays that are put on by student actors. However, while all employees and students at the university may attend these plays for free, anyone who is not directly associated with the university must pay a fee to attend. I think student plays should be open to everyone free of charge. That way, people in the local community could benefit from having a free entertainment option in town. It would also be good for the student actors, since it would help to ensure larger audiences at the plays.
Sincerely,
Marie Jones

Task3：
Phoresy
阅读材料
Phoresy
Animals often have to move from place to place to obtain resources. Most animals do so using their own physical effort, but animals of certain species may not be able to transport themselves efficiently in order to access the resources they need. These animals may make use of another animal species to transport them, without causing any injury to the other species. This relationship is known as phoresy. Phoresy, which is a temporary relationship, benefits the passenger species and causes little or no harm to the species doing the transporting.
问题
Explain how the example of the mite and the hummingbird in the lecture illustrates the concept of phoresy.
