Students must complete certain courses in their fields of study in order to meet the requirements for graduation. Currently, students meet with academic advisors to discuss these requirements. Soon, though, students will be able to use a new degree navigator Web site to keep track of their requirements The Web site will make it easier for students to monitor which courses they have already completed and which ones they still need to take before graduating, so they can plan their schedules accordingly Also, the Web site will help reduce the workload for academic advisors, who will not need to meet with students as often.

Task3：

Explain how the example from the professor’s lecture illustrates the concept of near-field sound detection.

Near Field Sound Detection

Some animals are able to use sound to avoid predators. When sound is produced, it creates vibrations in the surrounding air. These vibrations are known as near-field sounds because they originate： or begin, near the sound source. Most animals are unable to detect these kinds of sounds; however, some animals have an ability known as near-field sound detection This ability allows certain animals to detect vibrations or near-field sounds produced by potential predators Animals with near-field sound detection abilities have special physical features that allow them to sense an approaching predator and take action to protect themselves.
