On a hot September afternoon, Peter and his friend Isabel were on their way to the library. When they passed by Tubman park, Isabel suggested cutting through it to get to the library. As they entered the park, the sight of the swings (秋千) and the merry-go-round brought back a flood of memories of their childhood spent there. But now everything looked so old, sad, and dirty. Litter lay on the ground next to an overflowing trash bin. There were still young schoolchildren playing there but they had to avoid the trash that littered the playground. A little boy told them that the city took the other trash cans away and the remaining one never got emptied often.
As they headed toward the library, the two high school students wrinkled their forehead. In the library, they encountered Mrs. Evans, their kind-hearted fifth-grade teacher, retired yet still passionate. Mrs. Evans listened as Isabel and Peter eagerly explained what they’d seen. Finally, she recommended them to go to the City Hall to voice their concerns.
The next day, Isabel and Peter went into the building of the City Hall but were met with an impatient officer. They were informed that the city couldn’t help with their problem due to a tight budget. Discouraged, they left and turned to Mrs. Evans for help.
Under her guidance, they decided to ask Go Green, a non-profit organization whose goal is to protect the environment, for help. “This group is good at raising money for projects just like yours, ” said Mrs. Evans. She promised to arrange them to present their ideas to Go Green. Hearing this, their face lit up.
Two main tasks remained ahead: researching ways to clean up the park and preparing a convincing presentation. As Isabel was good at researching while Peter always had a talent for speaking, they cooperated quite well. Isabel learned from a science magazine that a new type of trash bin can squeeze the trash down without being emptied often, which saves time, money, and energy. Based on this, Peter practiced his presentation over and over again.

6 . Milwaukee, Wisconsin, is road testing a new way to keep winter roads ice-free – by spreading on them cheese brine, the salty liquid used to make soft cheese, like mozzarella.
Wisconsin, also called "America's Dairyland," is famous for its cheese. The state produced 2.8 billion pounds of cheese last year! As a result, there was a lot of leftover cheese brine. Disposing of(处置)the brine can be expensive. So what should cheese makers do with the waste?
Normally, towns use rock salt to de-ice streets. The salt lowers waters' freezing point, causing ice to melt(融化). But using cheese brine could help both cheese producers and cities save money, while keeping roads safe. Cheese brine has salt in it, which, like the rock salt, helps lower water's freezing point.
In addition to saving money, cheese brine could also be a more environment-friendly option. Many people suspect that all the rock salt used every winter is harming the environment.
Rock salt is made of sodium chloride, the sane con-pound (化合物)in ordinary table salt. Sounds harmless, right? But while you probably add only a small amount of salt to your food, road crews spread about 20 million tons of salt on U.S. Roads every year!
The chemical washes off roads and goes into the ground. There it can pollute drinking water, harm plants. and eat away soil. By spreading cheese brine on streets before adding a layer of rock salt, Milwaukee may be able to cut its rock salt use by 30 percent.
Cheese brine has a downside too – a shell similar to that of bad milk. "I don't really mind it," Emil Norby told Modern Farmer magazine. He works for one of Wisconsin's county highway commissions and came up with the idea of using cheese brine. "Our roads smell like Wisconsin!" he said.

| A．Improving air quality. | B．Increasing sales of rock salt. |

7 . The number of fish caught just outside a recently expanded marine (海洋) protected area in Hawaii has risen. It is a sign that quadrupling (四倍) the size of the reserve in 2016 may have shored fish populations in the region.
When the Marine National Monument around Hawaii was enlarged to 1,510,000 square kilometers, marine conservationists around the world rejoiced.
Fishers may have felt differently, however, as fishing inside the area is not allowed. Yet by creating a space for dwindling tuna populations to recover, supporters argued, the reserve would benefit fisheries as well.
As populations inside the reserve boundaries steadily increased, they predicted, the fish would spill (溢出) over into the surrounding areas, increasing the amount of tuna available to catch.
Proving that is tricky, however, as tuna can’t be counted directly. Their numbers may rise or fall for a variety of reasons other than the expansion of a reserve. But the new study, published in Science this week, strongly suggests the number of fish caught just outside the MPA is higher now than it used to be.
Alan Friedlander, chief scientist for the National Geographic Society’s Pristine Seas project, calls the study a “very careful and strict test of spillover from marine protected areas.”
Importantly, says John Lynham, an environmental economist at the University of Hawaii and one of the study’s authors, the increase in tuna catches near the reserve held up even when looking at the average numbers caught by particular fishers. This shows the effect is not due to more effective crews now fishing local waters, he explains. To account for effort, catch numbers were divided by the ever-increasing number of fishing hooks in the area.
Lynham and colleagues found the catch per hook increased over the 10 years of the study. Fishers were catching on average six more yellowfin and five more bigeye tuna per year after the expansion than before.
“That last one, especially, was a surprise,” says Lynham, “because it is economically much more important, and there were fewer indications of an increase.”

Sam was a junior high school student. He lived in a community in Charlotte and usually had little exposure to country life. So much of what he knew about plants came from text-books. Sam was a kind-hearted person. He longed for a chance to explore nature and he wanted to do his part to beautify the world.
Finally, the opportunity came. On Arbor Day (植树节), his class organized a trip to a local village to plant trees. Sam was excited about it and couldn’t wait to tell his mom the good news. So the next day, Sam and his mom went to buy some tools for planting trees, including a shovel(铲), a bucket, gloves and so on.
On the day of the event, Sam and his classmates arrived early at the starting point. It was a beautiful day and everyone looked particularly happy. With the tools in hand, Sam got into the bus with everyone else and headed off to their destination.
As soon as they reached the village, all the students were divided into three teams by their teacher. One team was responsible for planting the trees, one team for shovelling the soil and one team for watering the trees. At the teacher’s command, everyone started to do their job.
However, it was the first time that many of the students had taken part in planting trees, so they had no idea about how to start. Of course, Sam was one of them. Fortunately, their teacher was a middle-aged man from the countryside who had some knowledge of planting trees. In order to set an example to the students, the teacher started to plant trees himself. After watching the teacher plant the trees, everyone also became busy. Before long, they planted hundreds of trees. Sam watched very carefully, not wanting to miss any of the details. Finally, Sam learned how to plant trees by himself and felt happy.
