    One week later, the students entered the classroom and began sharing their stories{#blank#}3{#/blank#} (excited). One reported on helping a poor dog {#blank#}4{#/blank#}(abandon) by its owner. Another student told others about giving blankets away to the homeless. Gradually, more and more students developed the habit of doing such kind acts, from{#blank#}5{#/blank#} they benefited a lot.
