Topic discussed: Pterosaurs能不能飞

Notes

Reading: 

l 冷血动物不产生能量

l pterosaur像长颈鹿那么大,体重太重以至于 无法飞行

l 从化石判断,Pterosaur的后腿力量很小, 没法像鸟类那样快速奔跑或跳高,因此起来

Lecture: 反驳

l pterosaurdense covering hair,跟fur一样。即使外部很冷,它也可以保持身体温暖。因此,它不需要能量就能 飞

l pterosaur的体重在同等大小的动物中算是轻的。它是空心而不是实心的骨架结构。重量很轻,翅膀带的动

l 鸟类靠后腿起飞,而pterosaur靠四肢起飞

 

Glossary

pterosaur翼龙

hollow空心的

push off the ground起飞

 

 

背景知识

翼龙,希腊文意思为“有翼蜥蜴”,是飞行爬行动物演化支。生存于晚三叠纪到白垩纪末,约2亿2800万年前到6500万年前。翼龙类是第一种飞行的脊椎动物,翼龙的翼是从位于身体侧面到四节翼指骨之间的皮肤膜衍生出来的。较早的物种有长而布满牙齿的颚部,以及长尾巴;较晚的物种有大幅缩短的尾巴,而且缺乏牙齿。翼龙类的体型有非常大的差距,从小如鸟类的森林翼龙,到地球上曾出现的最大型飞行生物,例如风神翼龙与哈特兹哥翼龙,翼展超过12米,牙齿有10厘米长。

翼龙是一种已经灭绝的爬行类动物,共有近100多个品种。最大的翼龙,其翼长为三十九英尺(12m)。支撑翼龙飞行的翼膜结构,完全不同于其后能够飞行的脊椎动物鸟类和蝙蝠类翅膀结构。翼龙类由皮膜形成翼面,皮肤、肌肉、与其它软组织构成的膜,膜从胸部延展到极长的第四手指上。以其他指骨支撑著膜。翼龙的膜只附著在细长的一个指状物上,向后沿体侧延伸到膝盖;在颈部()之间有附加的皮膜。前面3个指骨为爪状的细长钩。其膜看来已完全适应飞翔和滑翔,但不如蝙蝠的膜或鸟类的翼灵活,而且较为脆弱。身体结实,后腿长而细,其构造表明不适应垂直移动或停歇,休息时靠后肢悬挂。

Essay question

Do you agree or disagree with the following statement: people should know about events happening around the world even if they have little influence on their daily lives. Use specific examples to support your answer.

 

Sample answer

We are living in an ever-changing world nowadays, with events happening everywhere. Many people are occupied with their own business and thereby choose to turn a deaf ear to the events which have, by their words, little influence on their daily lives. However, it doesn't seem sensible to ignore all these so-called irrelevant events. What we should value is actually the informative events and that's why we name our age as the Information Age.
No one can deny the fact that life is not only composed of daily routines, but leisure moments as well. Beside work, we also pursue for relaxations, yet we will have few choices if we solely focus on trifles around us. Taking sports for example, most people have their favorite sports team. When it comes to the latest game of the team, we will anxiously wait in front of the television, watching their performance with excitement, cheering or crying over the final result, and heatedly discussing about the game afterwards. Likewise, many other events such as political affairs or entertaining news involved with famous stars may also arouse people's interest. We find pleasure in these events though they have little to do with our own daily lives. Undoubtedly, knowing about current events can make us updated as well as engage us in conversations with other people.

Not only do global events trigger animated discussions, the knowledge can also lead us to better decisions if we can grasp the information behind them. In other words, many events don't seem to be influential on our daily life at first sight, which is true to some extent, but in the long run, quite a few will play an important role. World events like the political situations in Middle East usually don’t concern many people. However, political unrest and the most recent social movements there may indirectly affect oil prices. The global market largely depends on oil from the Middle East. If oil companies or even other business concerned with oil make predictions and decisions reasonably, they could make a fortune from these events.

Admittedly, it is not advisable to be mindful of everything that is happening in the world because we do not have so much energy and time. However, the importance of information can never be overestimated. We need to adopt time fragments to learn about what is happening around us even though it does not have affected our daily lives at this moment
