蜘蛛的网具有装饰作用。装饰的具体作用是啥? 经过实验发现，装饰可以反射紫外线，利诱蜜蜂使其认为是花反射的紫外线。因而蜘蛛经过这种方法来捕食蜜蜂。

经过比照类似的网，科学家得出了断论：网的装饰程度越凌乱，越可以前进捕食功率。因而越是饱食的蜘蛛越有精力去织凌乱的网。

可是，科学家对装饰的具体作用仍有疑问。一位科学家做了一组对照实验，他减去了用于支撑装饰的两根蛛丝，发现没有装饰的网反而捕捉到了更多的猎物。

那么装饰必定会有其他的优点来平衡这样的丢掉。经过实验发现，装饰可以使得蜘蛛网避免被鸟类发现；一起，母蜘蛛经过装饰来假装自个，使得自个可以平安的产下子孙。

第一种在水中的locomotion，鱼类在水里耗费的能量少是因为水供给浮力，鱼只用供给向前的动力。说到鱼的本身密度和水差不多，可以让鱼坚持浮在水里边。之后讲到鸭子，鸭子在水面游比在陆地还要多耗2倍能量，比鱼要多耗20倍能量，是因为在水面上游会发生一种bow wave，反向作用来对运动发生drag。鱼能很省能量是因为它完全submerged in water。还举了boat designer的比方。

第二种讲的是飞行为物，飞行为物要飞的比照快是因为抵达必定速度才干保证它能飞起来。而且飞翔的进程中还要战胜本身的分量，不只需供给向前的力，还要供给战胜重力的力气。Flying耗能排第二，空气密度小，所以既有lift力气，也有drag力气。

第三种讲的是陆地行走的动物，首要讲人的行走的locomotion，首要要战胜关节的冲突力fraction、重力，还有每一步行进的动力accelerate弛缓冲decelerate的动力。人行走比照耗能是因为每一步都要不断供给能量向前，每一步落下都要缓冲。Walking所所以耗能最大的。鱼和鸟比照省能量是因为不必缓冲。说到人骑自行车会比照省力，因为不必每次都缓冲。

Talk about a new activity that you did first which made you feel nervous at first.

【Response】

Something new I tried that made me feel nervous was ice skating. I grew up rollerblading and watching ice hockey, but didn’t actually go ice skating until I was thirteen. I had no idea if the fact that I could rollerblade would help me on the ice or not. I also had super high expectations because I had seen what hockey players can do on the ice. I almost felt sick with anticipation before stepping on the ice.

But that nervous feeling didn’t last for long. I fell almost immediately. It’s a little strange, but that actually made me feel better. I guess the worst part was just not knowing how well I’d do. Anyhow, I kept at it and now I’m great on the ice.

Task2

Some people think that libraries should be quiet because of study while others think that people could do some social activities and interactions there. Which one do you think is better?

【Response】

Yeah, of course libraries should be quiet. Definitely. Everywhere else in the city is noisy. It’s noisy inside and outside. Libraries shouldn’t be noisy, too.

Last week I went to the library to do homework because it’s noisy at my house, but there was a group of other kids talking and laughing the whole time. I was so angry! If I can’t go to the library to find some quiet, where can I go?

I mean, I get that students want a place for activities like study groups or something. But they can do that anywhere. Like, really, anywhere. Go to a coffee shop or even just sit outside somewhere. They don’t need to come into the one place that’s supposed to be quiet.

If you need to take a course, which professor’s course would you like to take?

（2018年3月3日的写作标题套路可以直接套用：you prefer to take a course taught by the professor with whom you have not had classes before or a course taught by the professor whose class you have taken before?）

The scenario asks me to choose between taking a course with the school’s most popular professor or with a professor who recently won an award for their research. I suspect most would say they’d prefer to study under the professor who just won the award. I understand why they might think that’s the better option, but they’re wrong. I’d prefer to study under the popular professor.

First off, the award-winning professor won that award for outstanding research. If the award were for outstanding teaching, then maybe I would consider taking that class. There’s a chance that the award-winning professor is one of those academics who is great at research but not great at helping others understand the subject. For example, I have a friend who always gets an “A” in every class, but he doesn’t have the communication skills to help others understand assignments. When he tries to help me, I end up more confused than when I started. Teaching is a skill, and I can’t be sure that the professor who is good at research has that skill.

Meanwhile, there must be a reason why students like the popular teacher more. Sure, we could be cynical and assume that students would favor a professor who gives them an easy workload. However, I like to give people more credit than that. Students are paying to learn, so they’re passionate about their subjects. From my experience, students want a professor who will make class interesting by inspiring their passion and preparing them for a career. Therefore, I think it’s a safe bet that the professor who won the “most popular” vote would be the teacher with the best teaching skills.

On top of that, the class with the popular teacher is likely to have the most motivated classmates. Popular classes fill up fast, and so the students who get into those classes are the s

tudents who dedicated time into researching the best professors and who made sure they were first in line to register for classes. Motivated classmates can take a good class and make it great. They make class discussions more valuable, group projects more productive, and they’re always up for study groups.

In short, the most important skills for a teacher is, of course, teaching. Award-winning research is great, but it doesn’t guarantee good teacher. The popular professor has proven to teach well and is more likely to have a class full of motivated students. That’s the class I’d choose.
