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.

3 . Here are some of the stereotypes or false impressions about Germany that we’re sick and tired of hearing.
Germans are unfriendly
If you’re living in Germany, don’t expect to make casual chat at the supermarket or bus stop. But it doesn’t mean Germans are unfriendly. The truth is that a lot of Germans are just more particular about when they socialize. If you’re in a space that’s made for socializing-anything from a dinner party to a nightclub-that cold shoulder you get in public will usually disappear.
Germans put efficiency ahead of everything
To some degree, it is true. For example, you might notice that the bus runs usually on time, and that there’s a lot of enthusiasm for recycling and careful uses of resources. On the other side, though, anyone who has lived in Germany might have had painful experiences with its public services. From taxes to gas bill, almost everything happens slowly and on paper.
German food is terrible
Ask foreigners about food in Germany and it’s likely that they will say it is too heavy on tasteless sausage and bread. But those complaints overlook a wealth of fantastic food, both cheap and fancy.
For one thing, Germany has 309 restaurants with Michelin stars, more than any other country except France, Italy and Japan. For those who don’t want to throw down € 100 on a meal, Germany also has a variety of bakeries. The country’s bread-making culture has its own UNESCO listing, and sweet treats from apple or cherry cakes to doughnuts are excellent, too.
1. Where do Germans most likely have small talks?A.In a gym. | B.In the office. | C.At the supermarket. | D.At a dinner party. |
A.The public transport isn’t well-managed. | B.Waste is rarely recycled. |
C.Online services aren’t easily available. | D.A lot of resources are wasted. |
A.Diverse. | B.Cheap. | C.Boring. | D.Expensive. |
4 . Proper questioning has become a lost art. The curious four-year-old asks a lot of questions-incessant streams of “Why?” and “Why not?“ might sound familiar-but as we grow older, our questioning decreases. In a recent survey of more than 200 of our clients, we found that those with children estimated that 70-80% of their kids’ dialogues with others were comprised of questions. But those same clients said that only 15-25% of their own interactions consisted of questions. Why the drop of?
Think back to your time growing up and in school. Chances are you received the most recognition or reward when you got the correct answers. Later in life, that motivator continues. At work, we often reward those who answer questions, not those who ask them. Questioning conventional wisdom can even lead to being distanced, or considered a threat.
Because expectations for decision-making have gone from ”get it done soon“ to ”get it done now“ to ”it should have been done yesterday, “ we tend to jump to conclusions instead of asking more questions. And the unfortunate side effect of not asking enough questions is poor decision-making. That’s why it’s vital that we slow down and take the time to ask more and better questions. At best, we’ll arrive at better conclusions. At worst we’ll avoid a lot of rework later on.
Aside from not speaking up enough, many professionals don’t think about how different types of questions can lead to different outcomes. We should lead a conversation by asking the right kinds of questions, based on the problem we’re trying to solve. In some cases, we’ll want to expand our view of the problem rather than keeping it narrowly focused. In others, we may want to challenge basic assumptions or confirm our understanding in order to feel more confident in our conclusions. Therefore, asking the right kinds of questions is what counts in achieving a goal.

7 . Making travel a surprise
Most people plan their vacations well in advance, including where they are going.
Earlier this year, mystery box purchases surged (激增) among young American people. Usually, travelers buy a mystery box at a low price—usually 100 or 200 dollars—and then receive several destination options to choose from.
A citizen named Carrie is eager to go on a mystery box trip, stating that travelling alone usually costs too much and that too many people don’t know where to go. ”However, the mystery box directly offers me a few destinations, which is wonderful and cheap,“ Carrie said.
Gary, 16, has turned his eagerness to go on a mystery box trip into a reality.

9 . It’s perhaps the world’s most famous underwater attraction that remained in film and in legend: the Titanic. But now experts say the ocean liner, once a wonder of the high seas, is falling to pieces.
Capt. Alfred McLaren, the scientist who in July led the most recent expedition to the ship’s underwater grave, said his team saw clear signs of the accelerating damage of the wreck (残骸). There was damage likely caused by rust and sea life, and the captain’s cabin had collapsed.
“I was absolutely astonished,” McLaren said.
Worse still, the fallen mast (桅杆) that crushed the ship’s deck is believed by many to be the result of an unapproved salvage (打捞) operation. “It was almost depressing to see how quickly she was getting worse,” McLaren says. “I would be really surprised if there’s very much standing up from the bottom, two decades from now.”
Ed Kamuda, who runs the Titanic Historical Society in Springfield, Mass., says adventure tourists — who pay $36,000 each to visit the wreck — are also contributing to the destruction of it.
“This is something I expected. I just didn’t expect it to happen so quickly,” Kamuda said. “People are going down just as an ego trip to say ‘I was there.’ All this takes a fare on the ship.”
The Titanic has sat at the bottom of the Atlantic since it sank after hitting an iceberg on its maiden voyage on April 14, 1912. More than 1,500 people died that night. The ship came to rest at the bottom of the freezing North Atlantic, more than 2 miles beneath the waves. The wreck was discovered in 1985, and since then it has been repeatedly visited by treasure hunters.
But still some scientists say those divers, and other thrill seekers are not necessarily to blame for the Titanic’s current problems.
Capt. Craig McLean of the National Oceanic and Atmospheric Administration went on an expedition to the Titanic in June as part of a government study that is monitoring the condition of the ship. He says it’s unclear what part of the damage is from Mother Nature and which is from human nature.
“It’s too early and there isn’t enough evidence to put our fingers on anything,” McLean said.
Regardless, most agree there’s little that can be done for this most famous of wrecks. And soon, the mighty Titanic could well be lost again.
