Task2
Reading:
University to Open Device Repair Center
People use electronic devices every day, such as cellular and smartphones, computer laptops, and more. But when these devices break down, getting them fixed can be inconvenient and expensive. That’s why the university has created a center on campus where students, faculty, and staff can help repair their own electronic devices in collaboration with experts from the university community. When your device has a problem, you can take it to the center and work with experienced volunteers to fix it for free, learning something in the process. Repairing these devices so they can continue to be used should also greatly cut down on electronic waste, which has become a big problem.
The woman expresses her opinion about the plan described in the article. Briefly summarize the plan. Then state her opinion about the plan and explain the reasons she gives for holding that opinion.
Task3
Reading:
Conservation-Reliant Species
Certain animal species are able to live only in a very particular kind of habitat. If that habitat is changed in some way, it may become difficult for that species to survive. If humans take action to conserve, or protect, that species, the species may become conservation-reliant; that is, it may become dependent on humans’ conservation efforts for its survival. These efforts often focus on recreating and maintaining the conditions in the species’ original habitat, conditions that no longer occur naturally. Such conservation efforts can help a species survive. If, however, these efforts are discontinued, the species may soon become extinct.
Explain how the professor’s lecture illustrates the concept of a conservation-reliant species.
Task4
