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.

6 . Lots of kids love video games, In fact they like them so much that they might hear something like this from Mom or Dad. “Enough! Find something else to do!”
It can be good advice. Why? Too much of anything is just too much. It’s true that some studies have shown certain video games can improve hand-eye coordination, problem-solving skills, and the mind’s ability to process information. But playing too much video games may lead to health problems.
It’s hard to get enough active play and exercise if you’re always inside playing video games. And without enough exercise, kids can become overweight.
Really overdoing video games also could affect other important things, like friendships and how well a kid does in school, And kids who play violent (暴力的) video games might act more aggressively.
But here’s the good news; Playing video games some of the time can be OK. Just choose quality games and limit (限制) screen time --- which includes TV, computer, smartphone, tablet, and video game time combined to no more than two hours a day.
A good game will be the right one for how old you are. Games are rated like movies and your mom or dad can help find out which ones you should use If you can choose one that gets you up and moving. that’s even better.

7 . Do you often dial others’ mobile phone number? Do you know China’s mobile phone has 11 digits. Why is this?
The 11 digits can be divided into three parts. Each part has a different meaning. The first three numbers tell you which mobile phone service provider you are using. For example, 135 is for China Mobile Communications Corporation (中国移动) and 188 is for China Unicom (中国联通). The fourth to the seventh digits tell you which area the number is registered (注册) in. And the last four digits are random (随机的).
The main reason for using 11 digits is that we have the largest population in the world. We once had 10 numbers. But as our population grew, there weren’t enough numbers for us to use. So we began to use 11 digits starting from 1999.
Eleven digits can be used to make billions of mobile phone numbers. That’s enough for each person to have seven or eight numbers to use.
What’s more, mobile phone numbers can be recycled. Usually, the service provider will reuse a canceled (取消的) number after three to six months. If you call a number that you haven’t contacted for a long time, you may find that its owner has changed.
Besides China, Britain and Japan also use 11-digit mobile phone numbers. But their numbers always start with 0. So they cannot create as many numbers as we can. Countries like the United States, Australia and India use phone numbers with 10 digits. Canada’s mobile phone numbers are perhaps the world’s shortest; they use seven digits.
