Extra-terrestrial:  Stupid humans!  Humans are stupid.  Stupid humans are constantly at war with each other, committing genocide and destroying the planet you depend on. Frontiers were drawn and territorial sovereignties were claimed -- although none of them exist naturally -- by stupid humans. So conceit you are, that you believe, you always knew more than others, and you were the smartest species on the planet. Humans, you are more than stupid!

我用中文再说一遍。愚蠢的人类！人类都是愚蠢的。愚蠢的人类总是兵戎相见，自相残杀，破坏自己赖以生存的星球。你们发明了国界和领土所有权，而这些都并不真实存在，因为你们是愚蠢的人类。不可一世的你们，永远认为自己比别人懂得更多，还号称整个星球中最聪明的物种。人类，你们真不配我用“愚蠢”两字来形容!

(I was trying to portray an intelligent alien who has full control of all terrestrial languages. She emphasized the two words “stupid” and “humans”. Her first two sentences just expressed her main idea. Then she used complex languages naturally and put “stupid” and “humans” at different places in the sentences. In the third sentence, she must begin the sentence with “stupid humans”. In the fourth sentence, she must end the sentence with “stupid humans”. In the fifth sentence, she must not use “stupid humans” and any of their synonyms at all, but express the same meaning. In the last sentence, she must separate the two words. My English is not good enough to achieve this. I hope that you could help me.)

Speaker A: The 20th century has witnessed two world wars, massive bloody killing, which lead to tragedies and disasters for mankind. Pollution caused by industrialization devastated the earth and threatened the survival of the species. Despite all these, human being is still the best life form on the earth.

Humans have great compassion. A deadly earthquake, richtered 8.0, took place in Wenchuan, China, in 2008. It claimed tens of thousands of lives, injured hundreds of thousands, and made countless people homeless. This was a time when people were genuinely in their great generosity and kindness. Wenchuan has received nationwide and international aids and support.

Humans have set up countries. Each nation has her own lifestyle, culture, and speaks different languages. These are the very feature that makes this world diversified and wonderful. How dull it would be, if there were only one lifestyle, one culture and one language! In spite of the differences, people seek common ground and are usually friendly to each other.

Humans are confident that they are very wise because they really are. They have advanced science and technology. Medical science has defeated illness; agricultural, hunger. With the industrialization progress, they have realized special responsibility to protect the environment and the ecological system. Governments of many countries encourage the development of new technology to tackle environmental challenges. By inventing machines and robots, humans spend less energy to have better lives than ever before.

They designed a kind of robot called “Ultraman”, to fight alien invaders and monsters, and I am the one built two decades ago. My name is Red. I have defeated …

Extra-terrestrial:  Excuse me, but I have to leave now.

Human: “Love is wise; hatred is foolish.” Smart humans have done many foolish things against our fellow terrans. It calls us to think. It calls us to return to the solidarity for the prosperity of all.
