Limit Borrowing Period for Library Books
Currently, students are permitted to borrow library books and take them home for one month before they have to return them.I think the university library should limit the borrowing period to two weeks.First of all,I think most students will agree that they do not need a whole month to read a book-two weeks is enough time. Plus, students who are waiting for a book to be returned so they can use it won't have to wait as long as they do now.This way they won't fall behind with their assignments.
Now, listen to two students discussing the letter.
(Man) Did you read this letter?
(Man) He makes some good points.
(Woman) You think so? I don't agree with him.
(Man) Why not?
(Woman) Well, to begin with, he's not thinking about how students actually use the books.
(Man) What do you mean?
In the letter, a student proposes that the university library should limit the borrowing period to two weeks. The woman in the conversation however doesn't agree with this proposal. First, she says that the proposal doesn't take into account how students are actually gonna use the books for writing。。。。余下范文省略！
Now listen to part of a lecture from a biology class.
So, okay, let me tell you about a great example of this. There's a bird, a type of heron that lives near rivers and marshes in Africa. Now this heron is a waiting bird. It spends most of its time walking around in shallow water. And during the day, it eats the fish that swim in the rivers and marshes. The trouble is, though, it can be pretty hard to see the fish with the sun shining on the water, because the sunlight creates a lot of glare and reflections, making it tough to see fish swimming below the surface.
The physical features of an animal's body usually serve a specific purpose-they function to increase the animal's chances of survival. But, over time, in response to a particular challenge in its environment, an animal species will sometimes use one of its existing features for a new purpose. This is known as exaptation. By finding another use for one of its physical features, exaptation allows animals to respond to additional challenges in their environment.The animal may continue to use the physical feature for its older purpose, while also using it for the new purpose.
In the lecture, the professor uses the example of the heron to illustrate the concept of exaptation. The heron is kind of waiting bird that spends of its time walking around in shallow water in the river, and it eats the fish there. But sometimes, it's hard for the heron to see the fish because the sunlight can create a lot of glare on the water.。。。。余下范文省略！
Listen to part of a lecture in a business class.
As you know, these days, people are becoming more and more conscious of how important it is to protect our natural environment, of how important it is to protect the atmosphere, the oceans, the soil, and so on.
And so more and more companies have now implemented environmentally friendly business practices. That is, they're running their businesses in ways that help protect the environment. For example, by conserving energy and preserving natural resources. And for business owners, there's some good news here. And that is, that environmentally friendly business practices not only benefit the environment, but they can also benefit the businesses themselves, and they can do that in a couple of different ways.
In the lecture, the professor describes two ways that environmentally friendly business practices can benefit businesses. First, they can help company save money by reducing their operating costs. For example, a coffee shop decided to change its regular light bulbs into special ones that can save more energy and last longer. This way the coffee shop.。。。。余下范文省略！
