Question

  Today the technologies of the human beings are developing rapidly ， but there are many unknown things waiting for us to explore in the world and we still have many strange questions. Among all of these puzzles ， maybe we are most interested in UFOs.

   It's known that UFO is short for the Unknown Flying Object. For a period of time,when we mentioned UFO,we always thought of aliens,the aliens' high-technology,outer space culture and so on. There are many witnesses in the world. They say for certain that they have seen some uncommon things in the sky with their eyes. Some of them can even prove(证明) their experiences with videos or pictures. But in the end people find most of the events are considered as natural phenomena (现象)or man-made objects. They just mistake a plane,a rocket ， a balloon or even a plastic bag for UFO.

   So far we haven't found real proofs (证据) to prove there are aliens and UFOs in space. But I believe ， with the development of the science,we will get more and more knowledge about our real world and we will have the ability to realize the essence (本质)of the world.
