Cities Plant More Trees to Cool Hot Streets
Many cities plant trees to lower street heat and help people walk outside in summer.
Many cities are very hot in summer. Hard roads and tall buildings keep the heat. So workers plant more trees on the streets. Trees make shade. Shade helps people walk and rest. Trees also clean the air a little. Some cities water young trees every week. Children help water them too. Cool streets make summer safer and nicer for families.

许多城市夏天很热。坚硬的道路和高层建筑会留住热量，所以工人在街上种更多树。树能遮阴，方便人们走路和休息，也能稍微净化空气。有的城市每周给小树浇水，孩子们也会帮忙。凉爽的街道让夏天对家庭更安全、更舒服。
