    A Colorado pair brings new meaning to the word “determination”. When one couldn’t walk and the other couldn’t see, they _______ up to share their love of the great outdoors.

Melanie Knecht has to use a wheelchair to get around due to born spina bifida (脊柱裂). Trevor Hahn only recently became blind after he _______ an eye disease five years ago. Both living in Fort Collins, Colorado, the two met at an adaptive boxing class — and they soon ran into each other again at an adaptive rock-climbing class.

They immediately _______ over Knecht’s lifelong hobby of camping and Hahn’s passion for outdoor sports. When she told him about her recent trip to Easter Island, where she got the _______ to be carried on another person’s back, an unusual idea occurred to her.

_______ his lost sight, he’d been able to scale a Himalayan peak, using poles and _______ directions from his companions.

They started small, but next month — with her vision and his _______— they will trek to the top of a 14,000-foot mountain.

“It just seemed like common sense. He’s the legs, I’m the eyes! _______, we’re the dream team.” said Knecht.

At the start of each hike, a friend lifts Knecht _______ a carrier on Hahn’s back. From that point on, she gives him oral directions to lead the way.

Hahn said, “It made me so happy to help someone experience what I’ve been able to experience my whole life. The best part is being able to make her smile — that gives me ________.”

In addition to this sense of purpose, the two share an understanding of how ________ it can be asking able-bodied or sighted people for assistance in everyday life. They get immeasurable ________ from being able to do this on their own.

While the two accept that others ________ what they’ve been able to do, they’re not looking for ________— they just want others to encourage solutions for their friends with disabilities. Don’t ________ them because you think they won’t be able to do something.

    If you were like most kids, your mother must have told you there were three no-no’s when it came to your fingers: Don’t put them in an electrical outlet, don’t stick them up your nose (at least not in public), and don’t use them when you are counting. 1. But experts in education and cognition now believe that using your fingers to do math is not only a perfectly good idea but may even help children become superior students.

It certainly makes sense. When children count on their fingers, they take an abstract concept — mathematics — and translate it into the most basic and visual form 2.. Even when we aren’t actually counting on figures, they still can help us on math problems.

3. It activates when we respond to heat, pressure, pain, or the use of a given finger.

Studying brain scans, researchers discovered that when students aged 8 to 13 work on subtraction (减法 ) equations, this region “lights up” on the scans, even if the students aren’t using their fingers. The more complex the problem is, the more activities are detected.

The connection between finger use and math ability has been proved on old-fashioned math tests as well. With their eyes closed, first graders were asked to identify which of their fingers a researcher was touching. 4.. When college students were given the same quiz, the highest scores once again performed best on calculation tests.

So what does all this mean? For one thing, parents and teachers shouldn’t discourage children from counting on their fingers. 5.. Memorizing the multiplication tables may help, but it is not the best option. “I would like to see interesting and creative representations of ideas.” says Jo Boaler, a professor of math education.

Recently, a series of activities have been designed to strengthen students’ perception of their fingers. Maybe in the near future, there will be only two no-no’s regarding the use of fingers.

A.There is a section of the brain, called the somatosensory finger area.

B.Researchers also stress that students simply learn better using visual tools.

C.The first two laws of fingers are as true as ever.

D.That may sound simplistic, but the researchers offer an interesting explanation.

E.Researchers found those scoring highest on the finger-ID questions scored higher on a math test.

F.Researchers are unimpressed by those students who finish quickly as well.

G.In fact, experts believe the brain is built to “see” any process with our fingers.

Young people in the United States do not have a strong understanding of the world and their place in it.

Two U. S.— based groups, the Council on Foreign Relations and the National Geographic, Society commissioned an online survey earlier this year. They wanted to know what young people educated in American colleges knew about geography, U. S. foreign policy, recent international events, and economics.

The survey was given to over 1,200 Americans between the ages of 18 and 26 years. All of them presently attending, or having previously graduated from, a 2- or 4-year college or university.

The average test score, out of 75 total possible answers, was 55 percent. The study identifies a few important problems. For example, only 30 percent knew that the only part of the U. S. government that can declare war is Congress. Only 60% of those taking the survey could identify Brazil on a world map.

Part of the problem, argue the organizers of the survey, is the internet. They say it is becoming harder to find high-quality information about world events amongst all the fake news and trivia which swamp the web. Forty-three percent of those questioned said they read about the news on Facebook.

Another problem is that most college courses do not require students to learn about international issues. If such information is not required, Richard Haass from the Council on Foreign Relations said, then the United States could have leaders like Gary Johnson. He was a recent presidential candidate who did not know about the Syrian city of Aleppo when a reporter asked him about it.

The survey results were not all bad. The young people also demonstrated a good understanding of climate change and renewable energy. And the majority of them said that international issues were becoming more important to them.

Haass says these findings suggest the need to find was to get good information to students, both in school and online. To help, the Council on Foreign Relations is creating a new program called CFR Campus, designed to help build knowledge about global issues.

    Artemis is NASA’s new lunar exploration program. Through the Artemis program, NASA will use new technology to study the Moon in new and better ways, and prepare for human missions to Mars.

NASA’s new rocket will carry the Orion spacecraft to lunar orbit. Then, astronauts will dock (对接) Orion at a small spaceship called the Gateway, from which the crew will take trips to the lunar surface in a new human landing system, and then return to the Gateway. The crew will return to the Earth aboard Orion.

NASA will test the rocket and spacecraft in flight, then send a crew for a test flight:

Artemis 1 will be a test flight of the SLS rocket with the Orion spacecraft with no crew.

Artemis 2 will fly SLS and Orion with a crew past the Moon, then circle it and return to the Earth. This trip will be the farthest any human has gone into space.

Artemis 3 will send a crew with the first woman and the next man to land on the Moon by 2024. The Artemis 3 crew will visit the Moon’s South Pole. No one has ever been there.

At the Moon, astronauts will:

Search for the Moon’s water and use it.

Learn how to live and work on the surface of another celestial body (天体) where astronauts are just three days from home.

Test the technologies we need before sending astronauts on missions to Mars, which can take up-to three years round trip.

The Moon is a good place to learn new science. NASA will learn more about the Moon, the Earth and even the Sun. The Moon is a “test bed” for Mars. The Moon is a place to show that astronauts will one day be able to work away from the Earth on Mars for long periods of time.

1.What is the aim of the Artemis program?

A.To help astronauts return to the Earth. B.To be ready for the landing on Mars.

C.To study the Mars using new science. D.To test the Moon landing spacecraft, Orion.

2.Which will be the achievement of the Artemis series?

A.Going to the Moon’s South Pole. B.Making the farthest trip into space.

C.Sending the first man to the Moon. D.Flying to the Moon with three persons.

3.What will Artemis astronauts do on the Moon?

A.Send astronauts to Mars. B.Run a three-year-long test.

C.Find and make use of water. D.Learn to live not far from home.

4.What can we conclude from the text?

A.It is possible to live on another planet now.

B.The crew will reach the lunar surface from the Orion.

C.NASA has sent the first woman astronaut to the Moon.

D.The Artemis program is of great help to Mars exploring.
