你认为如果没有科学我们的生活会怎样？
Science has had a tremendous impact on our lives. Without science, human life would be greatly shortened, and our basic necessities, food, housing and transportation would be greatly limited. We cannot understand the laws of the universe and explain various natural phenomena, so we cannot carry out innovation and development.
