If you're looking for a reason to care about tree loss, this summer's record-breaking heat waves might be it. Trees can lower summer daytime temperatures by as much as 10 degrees Fahrenheit(华氏度), according to a recent study. But tree cover in US cities is shrinking. A study published last year by the US Forest Service found that we lost 36 million trees annually from urban and rural communities over a five-year period. If we continue on this path, "cities will become warmer, more polluted and generally more unhealthy for inhabitants," said David Nowak, a senior US Forest Service scientist and co-author of the study. Nowak says there are many reasons our tree cover is declining, including hurricanes, tornadoes, fires, insects and disease. But the one reason for tree loss that humans can control is sensible development.
"We see the tree cover being changed, which means when we look at the photographs, what was there is now replaced with a parking lot or a building," Nowak said. "Every time we put a road down, we put a building and we cut a tree or add a tree, it not only affects that site, it affects the region." The study placed a value on tree loss based on trees' role in air pollution removal and energy conservation.
Nowak says there's a downside to trees too, such as pollen allergies or large falling branches in storms, "and people don't like sweeping leaves." But, he says, there are ways cities and counties can manage trees to help communities thrive. Urban forests especially need our help to replace fallen trees. Unlike rural areas, it is very difficult for trees to repopulate themselves in a city environment with so much pavement and asphalt(沥青). "A lot of our native trees can't actually find a place to drop a seed so they can regenerate," explains Greg Levine, co-executive director for Trees Atlanta. "That's why the community has to go in and actually plant a tree because the areas just aren't natural anymore."
Nowak says the first step is caring for the trees on your own property. "We think we pay for our house, and so we must maintain it. But because we don't pay for nature, we don't need to. And that's not necessarily true."

A 3-year-old boy who was lost in the woods for two days is now safe at home with his family. But Casey Hathaway told his rescuers that he was not alone in the rainy, freezing cold woods. He said he was with a friend–a bear.
The child went missing on January 22 while playing with friends at his grandmother's house in the southern state of North Carolina. When the other children returned to the house and Casey did not, the family searched the area for almost an hour before calling the police.
Police formed a search and rescue team to look for the young boy in the nearby woods. But two days went by and still-no Casey. Two days later, someone called the police saying they heard a child crying in the woods. Police followed up on the information and found Casey at about 9:30 that night. They pulled him out of some wild bush. He was in good health. Casey told the rescuers that he had hung out with a black bear for two days, a bear he called his "friend."
The police officer Chip Hughes spoke with reporters from several news agencies. He said Casey did not say how he was able to survive in the woods for three days in the cold, rainy weather. "However," the police officer said, "he did say he had a friend in the woods that was a bear that was with him." Hundreds of people helped in the search and rescue efforts, including some 600 volunteers, federal police and members of the military. Officer Hughes told reporters that at no point did he think Casey had been kidnapped.
Doctors at Carolina East Medical Center treated Casey for minor injuries. He was then released to his family on January 25. His mother Brittany Hathaway was on cloud nine and talked with reporters from a local news agency and thanked everyone who joined the search for her son. "We just want to tell everybody that we're very thankful that you took the time out to come search for Casey and prayed for him, and he's good," said his mother. "He is good, he is up and talking. He's already asked to watch Netflix. So, he's good."

Patience is of great important in our daily life. Once I waited a bus to come at a stop. 30 minutes past, but no bus came. Both upset and annoyed, I decided to walk on feet. But no sooner had I left than the bus had arrived. I thought if I had waited for one more minute, I would have caught it. If I chose to take a next bus, I would have to wait for other 30 minutes. Only then did I realize my problem. Be impatient will probably waste all the effort what we have put in. Now whenever I am about to losing my patience, I will think of this experience.
A Game of Light and Shade
It was a sunny day. I had gone up and down the tower when, outside the door at the foot, a blind man came toward me. In a moment, he disappeared up the stairs. I looked at the sign that said “To the Tower”, and decided to _______ him.
I caught up with him in the ticket office. There I was _______ to see the attendant (工作人员) selling him a ticket as if he were any other visitor. Then, with the ticket in one hand and _______ the wall with the fingers of the other, the blind man reached the stairs _________ to the hallway.
“That man is blind. What would a blind man climb up the tower for?” I said to the attendant, expecting him to show some _______, but he didn’t answer.
“Not the _______ certainly,” I said. “Perhaps he wants to _______.”
I bought a ticket and _______ up the stairs. The man hadn’t gone as far as I _______. A third of the way up the tower, I heard his ________. I slowed down and followed him at a little ________. He stopped from time to time. When he got to the balcony, I was a dozen steps ________. As I reached it, I saw him at the corner of the tower.
At last, after ten minutes, I ________ him. “Excuse me,” I said as politely as I could, “but I am curious to know ________ you came up.”
He smiled. “Coming up the stairs, you will notice how not just light but sun ________ into the tower through the narrow windows here and there, so that you can feel the ________ —the cool stairs suddenly become quite warm—and how up here behind the wall there is ________, but as soon as going opposite a window you can find the sun. There is no ________ so good as this for feeling the difference between light and shade. It is not the first time I’ve come up.”
The blind man seemed quite ________ just like a child who was enjoying his favorite games. He told me the truth that blind men can also find the beauty in life ________ they cannot enjoy the sights of the world.
