Some people like to send text messages when they need information.Others prefer to call people on their cell phones for the information they need.Explain which method you prefer and why.
Well,personally,I prefer to call people using my cell phone,because this can save me a lot of time.You know,editing some text messages will be time consuming.It may take me like half an hour to think about the wording,but if I just call them,I can just ask them about the information I need directly on the phone so I can save some time.。。。。余下范文省略！
Concerts on the Lawn
Several music students-friends of mine-have recently formed a new jazz band.I'd like to recommend that the university invite this jazz band to play some free concerts on campus.These concerts could take place in the afternoon:students would enjoy hearing live music while they relax between classes and other afternoon activities.And a perfect location for the concerts would be the open lawn area near the student center.Many students are in this area during the day,and the lawn has recently been improved;it's now a nice area where students can sit and enjoy the music.
Sincerely, Tim Sutcliffe
Now, listen to two students discussing the letter.
What did you think of Tim's letter? I don't know. It's a nice idea, but I don't think he's thought it through. I mean, he's not thinking about the problems it'll create. Like, what? Well, like, first of all, I don't think that's really the best time of day to do it, really. Yeah, a lot of students don't have time to just sit around and relax. They're studying and reading getting stuff done for their classes. So to be really distracting with loud music playing in the background, huh? Yeah, I。。。。余下听力原文省略！

However,the woman in the conversation doesn't like the idea .Firstly, she thinks it's not the best time to do it,because students don't have time to sit。。。。余下范文省略！
Now listen to part of a lecture in a biology class.
Now this can be seen in a certain type of small fish called the minnow.
Minnows are hunted by a larger fish called a lake trout. Some minnows have learned to react to the smell of lake trout, mainly by gathering close together and not moving around much, because this makes it harder for lake trout to find and eat the minnows. So scientists explored the phenomenon we've been talking about by conducting an experiment. They exposed a group of minnows to the odors of two different kinds of fish that the minnows had never seen before. 1 kind was another species of trout called a Brooke trout, which even though a different species was still similar in some ways to lake trout.。。。。余下听力原文省略！
Generalization to Avoid Predators
For animals to avoid predators and stay safe,they need to be able to identify which other animals might be dangerous predators.Animals can sometimes recognize new predators by their similarity to predators they are familiar with.This phenomenon is known as generalization.When they encounter an unfamiliar animal that has the same characteristics as a known predator,they generalize by behaving the same way they would to avoid the known predator.An animal's ability to generalize can vary based on how similar the unfamiliar animals are to the original predators;the more similar they are,the more likely the animal is to generalize.
The reading passage talks about generalization,which means animals can sometimes recognize new predators by their similarity to predators they are familiar with.In the lecture,the professor takes an example of minnows.Minnows are hunted by lake trout.And the've developed a way to react to the smell of lake trout.。。。。余下范文省略！
Listen to part of a lecture in an education class.
So we've been talking about how teachers can make a classroom run smoothly. And of course, it's important to have rules in the classroom to make sure students behave well. But just making rules doesn't guarantee that children are going to follow them. In order to make sure children will follow the rules, there are a couple of strategies that are helpful for teachers when they make rules.
One strategy is to explain the purpose of the rule, because if students understand why the rules exist, they're more likely to follow them. Let me give you an example. I used to teach elementary school, young kids. And at the beginning of the year, I talked to my class about how I didn't want them to have snacks, food, or drinks in the classroom. After I announced this rule, I explained why I didn't want them eating in class to keep the room clean.。。。。余下听力原文省略！
The professor talks about two strategies teachers use to ensure students will follow classroom rules.The first one is to explain the purpose of the rule.For example,the professor used to teach elementary school students.When she said that she didn't want them to eat or drink in class,she explained why.。。。。余下范文省略！
