Thanks二、阅读理解Passage 1Earth is a planet composed of rock and metal. Along with water, all life on earth requires oxygen, carbon, phosphorus, nitrogen and hydrogen. We are often referred to as carbon-based life forms. It is believed that these basic materials would be needed for the emergence of life elsewhere in the universe but some scientists argue otherwise, suggesting that life could form from different elements and materials.Life on Earth shows a wide diversity in forms, yet many contain basic similarities. Life is an ongoing process so it seems probable that life exists elsewhere in the universe in a multitude of different forms and stages of progression. Just as it is possible that life exists elsewhere in forms similar to the bacteria and viruses found on Earth, it is also likely that life forms may exist that are more advanced than humans. Even though many planets have harsh conditions in which life as we know it would not be able to exist, we should keep in mind that there are many creatures on Earth that can exist in harsh climatic conditions. Life could exist in the smallest organic molecules or in a form completely unknown to humanity that could go totally unrecognized. We assume that life could not exist on the giant gaseous planets, but it could very well be possible that some form of life completely beyond the scope of our imaginations may exist.We dont know whether life in any form exists on other planets elsewhere in the universe. Although we have made great strides in our search for extraterrestrial life and the exploration of space our technology is still in its infancy in the cosmic scheme of things. 1.

It seems possible that life exists elsewhere in the universe.B. It is likely that there are life forms which are more advanced than humans.C.
