Helen Thayer, one of the greatest explorers of the 20th century, loves challenges. She says, “I like to see what’s on the other side of the hill.” She has gone almost everywhere to do that.
In 1988, at the age of 50, she became the first woman to travel alone to the North Pole. She pulled her own sled (雪橇) with 160 pounds of supplies, and during her trip no one brought her fresh supplies. Along with her dog Charlie, she survived cold weather and meetings with polar bears. In fact, Charlie saved her life when one of them attacked her. Near the end of her trip, a strong wind blew away most of her supplies. The last week of the trip, she survived on a handful of nuts and a little water each day.
Helen goes to challenging places not only for adventures, but also for education. Before her Arctic journey, she started a website called Adventure Classroom. On the site, she shared her adventures in order to inspire students. She explained, “Although kids often see the world in a wrong way, without hope for their future, we work to inspire them to set goals, plan for success and never give up...”
Helen grew up in New Zealand. Her parents were athletes and mountain climbers. Following her parents’ example, she climbed her first mountain at the age of nine. Later, she climbed the highest mountains in North and South America and New Zealand.
In 1996, she took on another challenge—the Sahara Desert. She and her husband, Bill, walked 2,400 miles across it. In 2001, she and Bill travelled on foot from west to east through the Gobi Desert in Mongolia. They hoped to travel in mainland China into Sichuan and Tibet to study pandas.
Helen plans to continue taking trips. She’ll use her adventures, writings, photos and environmental works to create programs for her Adventure Classroom website. She wants to inspire her students to never stop facing challenges.

Can you believe your eyes? A recent experiment suggests that the answer to that question may depend on your age.
 Martin Doherty and some other scientists tested the perception (观察力) of some people, using pictures of some orange circles. The researchers showed the same pictures to two groups of people. The first group included 151 children aged 4 to 10, and the second group included 24 adults aged 18 to 25.
     The first group of pictures showed two circles alone on a white background. One of the circles was larger than the other, and these people were asked to tell the larger one. Four-year-olds recognized the correct circle 79 percent of the time. Adults recognized the correct circle 95 percent of the time.
     Next, both groups were shown a picture where the orange circles, again of different sizes, were surrounded by grey (灰色的) circles. Here’s where the trick lies in. In some of the pictures, the smaller orange circle was surrounded by even smaller grey circles—making the orange circle appear larger than the other orange circle, which was the real larger one. And the larger orange circle was surrounded by even bigger grey circles—so it appeared to be smaller than the real smaller orange circle.
    When young children aged 4 to 6 looked at these tricky pictures, they weren’t fooled—they were still able to find the bigger circle with the same accuracy (准确性) as before. However, older children often recognized the smaller circle as the larger one, and adults got it wrong most of the time.
     As children get older, Doherty said, their brains will begin to watch the whole picture at once: the grey circles, as well as the orange circle in the middle. As a result, they’re more likely to fall for this kind of trick.
22. Doherty and his team of scientists did an experiment to judge _________.
A. children’s and adults’ brains               
B. the influence of people’s age
C. people’s ability to see exactly
D. children’s and adults’ eyesight 
23. When asked to find the larger circle, __________.
  A. adults got it right most of the time with grey ones around
B. children at 6 got it wrong 79 % of the time with no grey ones around
  C. only adults over 18 got it right 95% of the time with grey ones around
  D. children at 4 got it right about 79 % of the time with grey ones around
24. According to the passage, we can know that __________.
  A. a smaller orange circle appears bigger on a white background
  B. an orange circle appears bigger than a grey one of the same size
  C. a circle surrounded by bigger ones looks smaller than its real size 
  D. a circle surrounded by other circles looks bigger than its real size
25. Why are younger children not fooled?
  A. Because they are smarter than older children and adults.
B. Because older people are influenced by their experience.
  C. Because people’s eyes become weaker as they grow older.
D. Because their brains can hardly link two similar things together.
