2 . An artist in Oakland, California is using his skills to help the homeless. Greg Kloehn builds very small shelters that make life on the streets a little more comfortable. The structures offer the homeless some safety and protection from bad weather. Each little house also has wheels on the bottom so it can go wherever its owner goes.

Greg Kloehn has given away at least 20 tiny houses. Several are on the roadside near an active railroad. On a recent day, Mr. Kloehn stops at one to visit Oscar Young. The two men hug. Inside his little shelter Mr. Young gets relief from cold nights on the streets. Mr. Kloehn also visits Sweet-Pea, another friend who also lives in one of the little homes the artist built. She says it keeps her safe and protects her belongings.

In the mornings, Mr. Kloehn searches the streets for building materials. He gathers what he can and takes it to his studio. There, he puts the houses together. Empty coffee bags become roof material. A washing machine door and refrigerator part become windows. Nails, screws（螺丝钉） and the sticky glue hold all the pieces together. The artist also attaches a small electrical device to the house. The device is powered by the sun.

Some of the people living on the streets once had normal houses of their own. But some of the people say they have learned to live with less and they are thankful to that man.

Mr. Kloehn says his work is not a social project. He says he is just someone using his skills to help his homeless neighbors.

3 . When public health officials started telling Americans that hand washing is one of the most powerful weapons against the spread of the coronavirus, Terence Lester wondered, “What about the homeless?” Lester had been homeless himself for a time as a teenager, and today he runs a nonprofit in Atlanta called Love Beyond Walls that helps raise money for and awareness of homeless people. He knows all too well that in the best of times they are lucky to find a public bathroom that will let them in to wash up occasionally, not to mention several times a day.

Lester’s experience of creating temporary shelters with his nonprofit led him to another idea: temporary handwashing stations, the kind you see at outdoor music festivals. He mentioned the idea to his friend Lecrae Moore, a Grammy-winning Christian rapper, who eagerly donated enough money to buy 15 of the $ 150 washing stations. They called their project Love Sinks In. “If leaders in this country are asking people to wash their hands, we also have to provide the tools to people living on the margins of society who are more likely to catch and spread the coronavirus,” Lester says.

After its success in Atlanta, the group sent sinks to Birmingham, Alabama; Oakland, California; Columbus, Ohio; and Austin, Texas, where a partner organization installed the sinks in parks and other public spaces, thanks to a $ 13,000 donation from Google. (In addition to the startup funds, it costs about $ 500 a month to keep each sink stocked with soap and clean water.) One Atlanta hand washer, Sam, left a note on a sink that said, “God bless you! The hand washing the others!” One Atlanta hand washer, Sam, made sure his gratitude didn't go unnoticed. He left a note on a sink that said，“Thank you all for not forgetting about us.”
