题目：Ifa foreign friend is goingto visityour hometown and doesn' t knowwhat to pack.what suggestions do you have for him?
If a foreign friend is going to visit my hometown, I'd definitely suggest him to pack two things. One of them is a map. I live in Beijing. If s a metropolitan city where one can easily get lost. For instance, there are 7 different subway lines that stretch out all around the city. When my cousin who' s born and raised in the US came to Beijing for the first time, he took the wrong subway line and ended up in a place out of nowhere and since he had no map and couldnot speak Chinese very well, he couldn' t ask for help. So I, d say a map is a necessity when you visit a place for the very first time. Besides that a smart phone would be a smart thing to pack too. A smart phone nowadays can solve all kinds of problems. For instance, last time when I went to Europe, I used Google translator on my phone to talk to local people. It was very convenient and a lot of fun as well.
题目：Some teachers let students choose topics that interest them on research papers. Others assign topics on research papers. Which one do you prefer?
I think it' s better if teachers let students choose topics that interest them on research papers for the following reasons. First of all, students will be much more motivated when writing about something they actually like. Take myself as an example, my second-grade English teacher Miss Mayim once assigned a research paper for us and she allowed us to write about whatever that interested us, so I decided to write about my favorite musical Cats. I worked very hard for it and I had more than enough motivation because I had fun learning about and writing about this musical. I gave up sleeping in during weekends and pulled all-nighters to work on this paper and I enjoyed every second of it. Secondly, students learn more when they write about things that interest them. Sometimes when teachers assign topics
on research papers, students are forced to write about things they take absolutely no interest in and they end up copying some random article on the internet. And that' s completely a waste of time and won' t help the students in any way.
Student in the letter proposesthat the university should create a web site for student musicians where theycould find people of the same interests and post information about concerts ormusic-related events. The woman in the listening likes it because firstly shesays that she and her friends always practice songs together, and they playrock music. But they don't happen to know a drummer who could play the drum. Butnow with the website, they could find one easily. Second, she says that whenshe goes to campus concerts, there are few people there. She thinks that'sbecause people don't know about those concerts. So now with the website, morepeople will come to the concerts.
The student suggests that the university should create a special website for student musicians due to two reasons. The first reason is that it will be easierto get in touch with people who share the same interests with them. The second reason is that it will be a convenient way to post information about concerts and events. In the conversation, the woman agrees with the suggestion. In the first reason, she mentions that she started a band with some of her friends and they always practice together, but they' re missing a good drummer in the band. If there was a website like this, it would be much easier for them to find a drummer for their band. As for the second reason, the woman points out that there are few people there when she goes to campus concerts and stuff because people don' t know about these events, this website could help people stay updated about music-related events on campus.
Signal redundancy means thatanimals will send the same message with different types of signals to informthe other animals of the same species. In the professor's example, he says thata group of deer sometimes will graze together and sometimes one of the deerwould go off and eat on its own. And when this deer sees a predator like a lionapproaching, it will raise its tails to inform the rest of the deer to run awayfrom the area. But sometimes the other deer cannot see the signal. So thisparticular deer will also dump its foot on the found to make some noise, whenother deer near the noise, they will run away.
In the lecture, the professor talks about the concept of signal redundancy which means animals will send the same message with different types of finals to inform other animals of the same species. He offers us an example to illustrate it. Deer sometimes graze togetherand once in a while one ofthe deerwill go offand eat on its own. When this deer sees a predator like a lion coming, it will raise its tail as a signal to alert the other deer so that they have a chance to run away from the area. But when the other deer miss this signal, this particular deer will instead stomp on the ground to make noise. And when other deer hear this noise, they will run away to a safer area.
Problem: a student hurt herselfwhen playing basketball. Got a pulled muscle. But she has important gamescoming up. First, stop playing to let the muscle recover faster. Second do someexercise before play games?
The woman, s problem is that she got injured while playing basketball but she has an important game coming up. There are two possible solutions for him. The first one is to join the game anyway. And second solution is to take a rest and give herself some time to recover. If I were in her shoes, I’dgo for the second solution
because with the proper treatment she will be able to recover pretty soon and I'm sure there are a lot of other opportunities for her in the future. I personally don' t recommend the other solution because it will definitely make her injury worse and may even cause long-term muscle injury. It' sjust notworth it to give up her health for this one game. That, s why in this case I think the second solution is a much smart option.
