Many of humans' great achievements are in science and technology. The list is almost endless. The 26.1.(invent) 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 27.2.(live) without electricity? What about the printing press? Without the printing press, you wouldn't be reading this. In the last 50 years, there have been great achievements in 28.3.(communicate), such as radios, TVs, computers, the Internet, and smartphones(智能手機). We could probably live without them, but life wouldn't be as 29.4.(interest) as it is now.

What about the arts? The arts have brought 30.5.(please) to many people, but are the Beatles and Bach more important than antibiotics? And is Mickey Mouse as important an achievement as going to space? 31.6.(final), we must not forget humans' early achievements. They used fire for cooking and 32.7.(heat) and invented the wheel. We can't imagine modern life without 33.8.(cook) food and cars.

What are humans' greatest achievements? To answer the question, we need 34.9.(decide) what we mean by “great”. Is it something that 35.10.(make) us rich or happy or save lives? Or is it just something that makes us say “Wow，” like the Great Wall? What do you think?
