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(智能手机). 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?

On Sunday it was sunny. More than ten people were standing on the airport waiting for the challenge for skydiving (跳伞). Suddenly, with the help of a guide dog, a blind man was coming with a parachute (降落伞) on his back.
“Do you also come for the parachute training?” someone asked. “Yes!” the blind man replied in a loud voice. All the people looked at him in surprise. “I know. Are you wondering how a blind man can parachute?” the blind man said cheerfully. “Yes, how can you parachute?” Seeing the blind man was so cheerful, they asked quickly.
“It's not difficult. I'll parachute like you. Although I am a blind man, I can hear! When I hear the order for skydiving, I'll carry my guide dog to follow you one by one. The coach says, counting to 5 from the moment I jump down, I can open the parachute. And I know when to fall to the ground is the most dangerous moment in skydiving. But it's very simple for me. When my guide dog is scared into crying loudly and the rope in my hand becomes light, I'll prepare for falling to the ground,” said the blind man quietly.
After the challenge, the coach told everyone, “In this training, Robert gets the highest score for his most standard and placid (从容的) action.” “Who's Robert?” They asked simultaneously.
“He!” the coach said, pointing at the young blind man.

A. To watch the parachute training.
B. To train his guide dog.
C. To join in the parachute training.
D. To go traveling by plane.
2.How did all the people feel when the blind man wanted to parachute with them?
A. Happy. B. Surprised.
C. Excited. D. Sad.
3.What does the word “simultaneously” mean in Chinese?

C. 不可否认地 D. 不约而同地
4.According to the passage, which of the following is NOT TRUE?
