Humans’ Greatest Achievements

The earth is 4.5 billion years old, but the human race has lived on it for just 200,000 years. In that short time, we have achieved some amazing things.

1.The list is almost endless. The invention of the airplane has changed our lives. The discovery of antibiotics(抗生素) has saved the lives of millions of people. Can you imagine living without electricity? What about the printing press(印刷術(shù))? Without great achievements in communication, such as radio, TV, computers, the Internet and smartphones. 2.

What about the arts? The arts have brought pleasure to many people, but are the Beatles and Bach more important than antibiotics? 3.

Finally, we must not forget humens’ early achievements. 4. We can’t imagine modern life without cooked food and cars.

What are humans’ greatest achievements? To answer the question, we need to decide what
