【題目】閱讀短文，回答問題

When an animal helps another animal, it usually gets something valuable (有價(jià)值的) in return. For a long time, many scientists thought that only people could act generously (慷慨地) just because it feels good.

However, a new study in Germany suggests that chimpanzees (an animal like a large monkey without a tail) also do good things for no real reason. And so do children who are as young as 18 months of age. Maybe it is because humans and chimpanzees share an ancestor about 6 million years ago.

People and chimpanzees appear to develop such features without any other training, says Warneken, a scientist in Germany.

Warneken and his partners worked on adult chimpanzees that live on an island in the African country of Uganda. They also worked with 18-month-old children in Germany. The researchers performed three experiments on the adult chimpanzees and two experiments on the kids. In the first animal experiment, a person tried to reach his arm into a cage to get a stick, but he couldn't reach it. A chimpanzee was in the cage, and it could reach the stick if it wanted to.

Thirty-six chimpanzees took part in this experiment one by one, and no chimpanzee saw what the other chimpanzees had done. Even though the animals hadn't met the person before, they usually took the stick and gave it to the person. What's more, they did this whether or not the person gave them bananas as a reward (獎(jiǎng)勵(lì)).

In a similar experiment, 36 children acted in a similar way. They helped the person reach the stick, whether or not they were given toys for their help.

Researchers did other experiments on chimpanzees and babies. No rewards were given in either experiment. And still, both the chimpanzees and children went out of their way to help.

【題目】 Most of us probably dreamed about becoming an astronaut when we were little. But how many of us have actually become one, or are at least working toward it? It’s true that 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 (候選人) 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 began to dream of going to mars when she was only three years old. After watching an astronaut-themed cartoon and hearing from her father that humans had only been to the moon but not Mars. Carson decided that she wanted to be the first one to do so.

To realize her dream, she has worked hard toward it. At the age of 12, Carson became the first person to attend all three NASA space camps, and she sat with real astronauts 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. “I’ve just really focused myself on what I want to accomplish.”

Besides, Carson is willing to make sacrifices (犧牲) 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.”

While some people’s dreams may sound out of this world, Carson is on her way.

【1】Where is Carson from?

【2】When did Carson begin to dream of going to Mars?

【3】What languages is Carson learning?

【4】Why can’t Carson get married and start a family?

【5】What does Carson do to follow her dream?
