Most of us probably dreamed about becoming an astronaut when we were little. But how many of us actually became one, or are at least working toward it?
The advice “Always follow your dreams” is something that is typically easier said than done.
But still, this is the one piece of advice that Alyssa Carson wants to share with her peers. This 17-year-old girl from the US has become one of the candidates for NASA’s 2033 project to go to Mars. If everything goes well, Carson will be one of the first human beings to ever set foot on the red planet.
Carson has dreamed of going to Mars since she was only three years old. Watching an astronaut-themed cartoon and learning that humans have only been to the moon but not Mars, Carson decided that she wanted to be the first one to do so.
Since then, she has worked hard toward this goal. At the age of 12, Carson became the first person to attend all three NASA space camps, and she sat with real astronauts in a NASA panel(座谈会) to discuss the future of Mars missions.
Now 17, Carson is continuing with her space training while still taking on her high school work like a “normal” teenager, except that she studies all her subjects in four languages – English, French, Spanish and Chinese.
“I don’t think there’s anything specific that makes it easier for me or makes it something that others can’t do,” Carson said in an interview with Uproxx News. “I’ve just really focused myself on what I want to accomplish.”
And Carson is willing to make sacrifices for her dream. She’s fully aware of the danger of the mission and the possibility that she might never be able to come back. She also accepts the fact that she can’t get married and start a family because any loved ones left on Earth may be a distraction for her and for the mission. But Carson believes that it’s all worth it, summarizing her view with this ancient Greek proverb she once quoted, “A society grows great when old men plant trees whose shade they know they’ll never sit in.”
So after all the hard work that Carson has done and all the sacrifices she’s made, everything still boils down to the simple phrase, “follow your dreams”. And while some people’s dreams may sound out of this world, in Carson’s case, they literally(毫不夸张地) are.

Tiny as they are, bats have the ability to “see” in the dark by using a special skill called echolocation(回声定位法). They make noises and wait for sound waves, or an echo, to bounce(反弹) back off objects. They can tell the distance of various objects by how quickly the sound waves bounce back off them. If no sound bounces back, they can then fly forward.
This special ability has been simulated in the human world for a long time, such as in submarines and planes, whose sonar(声呐) systems are somewhat similar to echolocation. But apart from helping vehicles “see” where they are, what if blind people could use echolocation for themselves? It turns out, some already are.
American Daniel Kish, who is blind, is known as “Batman”. This isn’t because he walks around in a cape and a mask, but because he has a bat-like ability to locate where he is through sharp clicks he makes by moving his tongue against the roof of his mouth. Kish is so skilled at echolocating that he can ride a bike and hike on his own.
Recently, research carried out at the University of Durham in England shed some light on the power of human echolocation.
Kish worked with a group of scientists who studied the way blind people listen to the echoes that they produce from clicks.
The team, which conducted experiments with other volunteers, found that people were capable of hearing even very faint echoes, ones far fainter than had been previously thought.
Speaking to The Independent, Lore Thaler, lead scientist of the group, said, “We found that in some conditions, they were really faint – about 95 percent softer than the actual clicks, but the echolocators were still able to sense this.”
Andrew Kolarik of the University of Cambridge is another expert in echolocation. Reacting to the Durham study, he told BBC News that echolocation “can be very useful at providing information at face or chest height” and could help people “avoid objects like low hanging branches that might not get detected by the cane or a guide dog”.
Although Kish’s skill is remarkable, there’s hope for other blind people who want to use echolocation. According to BBC News, echolocation is a skill blind people can acquire and develop, just like learning a language. As Kolarik said: “Teaching echolocation skills could provide blind people with the means of exploring new places.”
1.The underlined word “simulated” in Paragraph 2 probably means _______.
A. discovered B. copied

A. By using his great sense of hearing.
B. By listening to the echoes produced by his cane.

3.What did Lore Thaler’s team find from their studies?
A. It is hard for echolocators to sense faint echoes.
B. Humans can echolocate better than we thought we could.
C. Echolocators can pick up all types of echoes.
D. Blind people are better echolocators than those who can see.
4.According to the article, teaching echolocation to blind people _______.
A. will enable them to get rid of their cane
B. will improve their ability to learn a new language
C. will open up new possibilities for them
D. is not easy to put into practice
5.What is the article mainly about?
A. Studies on blind people using echolocation.
B. Different types of human echolocation.
C. The importance of human echolocation.
