1 . In the rich countries of the West, the electric vehicle revolution is well occurring. Climate-conscious consumers drive Teslas or Polestars for reasons of morality (道德) and fashion. Poorer countries are also experiencing a wave of electrified trend. In Bangladesh, electric three-wheeler taxis, known as tuk-tuks, are rapidly replacing gas-powered ones on the streets. Such electric vehicles are climate friendly, cost effective, and help reduce air pollution.
Yet a glance under the hood (引擎盖) of these vehicles shows a poisonous secret: each tuk-tuk runs on five massive lead-acid batteries (铅酸电池), containing almost 300 pounds of lead (铅) in total. Every year and a half or so, when those batteries need to be replaced and recycled, about 60 pounds of lead leaks into the environment. Battery recycling, often at small-scale unregulated factories, is a highly profitable (高利润的) but deadly business.
Lead is dangerous, and any exposure to it is harmful to human health. Lead that has entered the environment hurts people on an unexpected scale. The numerous ways lead enters air, water, soil, and homes across the developing world and the enormous damage it does to human health, wealth, and welfare cause one of the biggest environmental problems in the world yet receives little attention.
The World Bank estimates that lead kills 5.5 million people per year, making it a bigger global killer than AIDS, malaria, diabetes, and road traffic deaths combined. On top of the shocking deaths, the social burden of lead poisoning is heavy, as is its contribution to global inequality — our research on the cognitive (认知的) effects of lead poisoning suggests that it may explain about one-fifth of the educational achievement gap between rich and poor countries.
But unlike many challenges faced by developing countries, lead poisoning is a problem that can be resolved through financial investment (财政投入). Better monitoring, research, and rules can help protect children all over the world from the unpleasant effects of lead poisoning and reduce the massive global costs it brings.

A Little Boy
A little boy selling magazines for school walked up to a house that people rarely visited. The house was very old and shabby and the owner hardly ever came out. When he did come out, he would not say hello to his neighbors or passers-by but simply just glared at them.
The boy knocked on the door and waited, sweating from fear of the old man. The boy’s parents told him to stay away from the house, and a lot of other neighborhood children were told the same thing from their parents.
Dusk found the boy lingering on and hesitating what to do. As he was ready to walk away, the door slowly opened. “What do you want?” the old man said impatiently. The little boy was very afraid but he had a quota (定额) to meet for school with selling the magazines. So he got up the courage and said, “Uh, Sir, I am selling these magazines and, uh, I was wondering if you would like to buy one from me.”
The old man just stared at the boy without a word. The boy could see inside the old man’s house and saw that he had dog figurines (小雕像) on the fireplace mantle. “Do you collect dogs?” The little boy asked. “Yes, I have many collections in my house. They are my family here and they are all I have.” The boy then felt sorry for the man, as it seemed that he was a very lonely soul.
“Well, I do have a magazine here for collectors. It is perfect for you. I also have one about dogs since you like dogs so much.” The old man was ready to close the door on the boy and said, “No, boy. I don’t need any magazines of any kind, now goodbye.”
The little boy was sad that he was not going to make his quota with the sale. He was also sad for the old man being so alone in the house that he owned. The boy went home and then had an idea. He had a little dog figurine that he got some years ago from an aunt. The figurine did not mean nearly as much to him since he had a real live dog and a large family.

As for Hallie Barnard, who was born with a rare blood disorder, a song, whose main idea is about a good friendship turning bad like the bad blood, meant a lot to her. The song represents her inborn struggle with a unique blood condition and the impact it has on her life.
At just 15 months old, Hallie was diagnosed (诊断) with Diamond-Blackfan anemia(DBA) , and she spent most of her life in and out of the hospital. Hallie said she relied on the singer to bring her joy. The only way to survive DBA is with a bone marrow transplant (骨髓移植) and Hallie was eager for one. But she knew thousands of other patients were, too.
So, a few years ago, she decided to do something about it, creating her own foundation, Hallie’s Heroes. “It started selfishly as just trying to save my life, but then we realized there’s so many other children out there that needed a bone marrow transplant.” she said. “So, so far we’ve tested over 8,000 people and we found over 300 matches.” After a 9-year wait, Hallie got her own match through her own foundation. The recovery was hard, but Hallie said she stayed hopeful. “I would just kind of daydream. And sometimes I would listen to her music and I would daydream about the singer and meeting her and seeing her in person,” Hallie said in her social media.
When the singer’s assistant heard about Hallie’s Heroes and knew about her wish, he was inspired to help the selfless little girl who turned her own health battle into a way to help others and decided to give Hallie the surprise of a lifetime. He offered two tickets to the singer’s concert in Houston. When Hallie received a call offering her the tickets, she was shocked and enthusiastically accepted and attended the concert with her mother in the front row.
Now Hallie has recovered. She no longer has “bad blood”. Thanks to her foundation, hundreds of others can say the same.

9 . Laughing is good for mind, body, and soul. Here are five healthful benefits that may inspire you to laugh every day.
Lower blood pressure
Laughing involves taking quick deep breaths and then exhalations at intervals, which stimulates blood flow. A study of what science refers to as “merry laughter” shows that blood pressure that increases and then decreases becoming lower than it was before the laugh.
Natural pain killer
When you laugh, especially from the belly (腹部) , you are using many muscles. Along with laughter comes increased breathing which, in turn, sends blood that has been enriched with oxygen to the brain and throughout the body. This natural form of exercise even burns calories. Add laughter to your exercise routine. You could burn 10 to 40 calories after 10 to 15 minutes of laughing!
Laughing uplifts you
The act of laughing is something to increase those feel-good hormones called endorphins. These endorphins make people feel uplifted. Laughing also provides brain food.
Strengthen your immune system (免疫系统)
Aside from eating a healthy diet and taking vitamins, a good dose of laughter is important.
| A．Provide a workout |
| B．So laugh aloud every second |
| C．Laughing helps reduce tension |
| D．If you are feeling aching, turn on your favorite comedy |
| E．When you have a good laugh, you will have fun and feel good |
| F．This reduction in blood pressure also offers benefits to your heart |
| G．Research shows that laughter therapy positively affects the immune system |
10 . Here are four unique national parks in the US that will make you feel like you’re on another planet.
White Sands National Park, New Mexico
This national park in New Mexico is home to the largest area of gypsum sand dunes (沙丘) , making it a truly otherworldly destination in our own backyard. The sand may look like snow, but it can definitely get hot out there. Bring water and a sled (雪橇) , because it’s a popular place for sledding.
Great Sand Dunes National Park & Preserve, Colorado
From some angles, you would think you’re in the middle of the Sahara while walking through the Great Sand Dunes National Park & Preserve in Colorado. But if you simply find a place with a good view, you can spot the beautiful Rocky Mountain. Occasionally, the nearby Medano Creek will overflow and create a sort of natural “water slide” that makes this usually dry area extra fun. The park is home to wetlands, lakes, and forests, in addition to sand dunes.
Dry Tortugas National Park, Florida
Even though it’s one of the least-visited national parks in the country, it’s definitely one of the best national parks in Florida. Located about 70 miles from Key West, this park is made up of several islands that feature blue waters, white-sand beaches, colorful marine life, and one of the largest 19th-century forts (城堡) in the US. The only way for anyone to access the park is by boat or seaplane, but the trip is well worth it.
Bryce Canyon National Park, Utah
If you’re looking for interesting red and pink rocks, you can’t miss this national park, which is known for its fascinating rock, as well as its gorgeous starry (布满星星的) skies at night.
