Kendall spends a lot of time playing in the dirt(泥土). She has a huge garden that _________ over 100 pounds of food each year! But for this seven-year-old girl, gardening isn’t just about fruits and vegetables. It’s about _________. “My favorite thing about growing food is doing it with my family and friends.” she says.

Kendall began gardening at age three when her great-grandmother gave her some fresh vegetables. “Grandma Kate told me, ‘Don’t throw away the stems(茎), because _________ you put them in the ground, they will grow back.’” Kendall tried it and was _________ amazed when the stems grew new leaves one day.

Soon after, her parents _________ a small backyard garden. When friends came over, Kendall enjoyed sharing what she knew. _________, she says, “My friends helped me water and care for the plants.”

At age six, she became the _________ professional farmer in Georgia. Today, her garden has grown to include sixty plant beds and twelve trees! When the vegetables and fruits are ready, Kendall says, “I pick them, then I do a food _________ so other kids and families can buy some.” People without enough food are welcomed to get what they need.

Kendall wants to _________ other kids too. She speaks at libraries and schools and hosts a community garden club for kids. “Growing food takes a lot of work. But together __________ is difficult.” she says. “So I invite kids to visit my garden and help me with it, to see how fun it is.”

“Military-style” travel has become the latest fashion among Chinese college students, who spend as little money as possible to travel to as many places as they can during the weekend, hardly taking a break or even sleeping.

Hu Die, a college student from Inner Mongolia, is one such traveler. On April 26, she took a high-speed train from Hohhot to Tai’an, Shandong province, to climb Mount Tai. It took her about four hours to climb to the top of the mountain and, after enjoying the beautiful sunrise on April 27, she went down to visit Dai Temple at the foot.

She then went to Jinan in the afternoon, visited Daming Lake and Quancheng Square in the evening, and on the morning of April 28 went to Baotu Spring and Heihu Spring. Next, she traveled to Zibo and, after eating the famous BBQ in the city, went to Yantai and Weihai before May 4, when she arrived in Luoyang, Henan province. There, she visited the Longmen Grottoes and then returned to her university on May 5.

“We do not think we are doing something ‘crazy’ or ‘unbelievable’. We are young and energetic enough to experience such a busy travel schedule,” she said. “Moreover, when you travel with your friends, you are happy, and after the adrenaline(肾上腺素) kicks in, you do not feel tired.”

For many university students with no much money and time, the wish to see the world and travel independently is a basic drive. These young travelers are less interested in in-depth experiences and more focused on checking off popular tourist places on their travel plan. This has led to the fast growth of a type of tourism where travelers would rather give up comfort and luxury(豪华) for affordability and convenience.

It is believed that robots could one day be our friends, but until now they have always seemed more machine than person. A new study has found that in fact it’s possible for robots to fool us, they just have to be less than perfect.

Wykowska, a researcher, came up with a test using a child-sized robot called iCub. In the test, people were asked to press a button(按钮) when a green box appeared on a screen, while iCub reacted(反应) to red boxes. Wykowska programmed the robot to take different lengths(长度) of time to react, just like a person would. After that, people couldn’t tell whether they had been competing with a machine or a person according to the timings of pressing the buttons. She believes that making robots have more human reactions is the key to making better robots and creating more trust between humans and robots.

In another study with iCub, the robot and a man watched videos together. In the first test, iCub greeted the man, and asked for his name. It shared opinions about the videos, laughed and showed expressions such as surprise and joy. In the second test, however, iCub did not communicate and just made machine-like noises. The team found that people in the first test were more likely to believe that the robot had its own thoughts.

The team now wants to know if people can build up closer relationships with machine-like robots that still show human-like behaviors. They plan to repeat the tests using robots of different shapes and sizes, to check how people react.
