1 . When scientists go to a forest to study monkeys and their habits and behaviors, how do they know who’s who?
In the past, scientists had to make marks on each of the animals to distinguish them. But in the future, they may have a much easier way to tell them apart thanks to facial recognition technology.
A research team from China’s Northwest University is using facial recognition technology to identify thousands of snub-nosed monkeys that live on Qinling Mountain in Shaanxi province.
Similar to human facial recognition, the technology that is used to identify monkeys uses their facial features to create a database that includes every monkey, Xinhua reported. “When the system is fully developed, we can connect it with cameras set up in the mountains. The system will automatically recognize the monkeys, name them and analyze their behavior,” said Zhang He, a member of the research team. “For each snub-nosed monkey, we have 700 to 800 image samples, and the recognition success rate is 94 percent,” Zhang added.
“We used mobile phones and portable cameras with the monkeys in tests at distances ranging from about 3 to 10 meters,” said He Gang, a member of the research team and an associate professor in the College of Life Sciences at Northwest University. “There is no need to interfere with the monkeys. Such a method of sampling is clearly non-invasive.”
Compared to humans, facial recognition technology for monkeys is more complicated because of their hairier faces. The color of their hair causes them to blend into their environment. These factors make it harder for computers to identify them.
“Monkeys do not cooperate with researchers in the same way humans do. It is difficult to take high-quality pictures and videos of them, which are needed to improve the system,” said Li Baoguo, leader of the research team.
Currently, there are about 4,000 snub-nosed monkeys living on Qinling Mountain. The team’s goal is to successfully identify every monkey that lives there.

3 . “Psychological well-being(心理健康)” is important to a person. Studies have discovered that people with higher psychological well-being are more likely to live healthier and longer lives. They are also more likely to enjoy a better quality of life.
Living a life with meaning and purpose is key to improving your psychological well-being. Your purpose doesn’t necessarily have to involve(涉及)changing the world or setting a goal of helping others though.

4 . If you’ve been dreaming of having an electric car, but can’t yet afford to buy one, you can start at a low price, really low. Changli, the world’s cheapest electric car, can be ordered online and sent to your door for just $930.
Designed and produced by Chinese maker Changzhou Xili Car Industry, Changli, and Changli Nemeca is a small electric car that has got lots of attention online after being advertised as the world’s most affordable electric car. Calling this thing a car is kind of stretching (夸大) it a bit, as its electric motor can only produce 1.16 horsepower, and it has a top speed of only 30 km/h. Still, it does come with some interesting features, like air-conditioning, independent suspension (悬架), heater, radio and even reverse-view camera. But the most impressive thing about Changli, in my opinion, is that you can have it sent to your doorstep.
Anyone who can just order Changli Nemeca online can have it mailed to them without having to pay extra money to the dealership. Changli measures 2.5 meters long, 1.5 meter wide, and 1.8 meters high, weighs 323 kilograms and can carry up to 300 kilograms.
The two-seat version (车型) starts at $930 ($1, 200 with larger batteries), but you can choose a three-seat version as well, which will cost you $1, 500. The battery of the Small electric car is between 40 and 100 kilometers per charge(充电) and the batteries take between 7 and 10 hours to charge.
While Changli Nemeca won’t be going head to head with other electric cars anytime soon, it’s still an amazing piece of machinery for the price. Where else are you going to find full functional electric cars that you can have mailed to your door.

5 . Astronauts(宇航员) aboard the International Space Station (ISS) recently tested an oven they used to bake(烘烤) five chocolate chip cookies. The cookies that came out best required two hours of baking time inside the International Space Station. The baking time for cookies on Earth is generally only about 20 minutes.
The American company Nanoracks designed and built the cookie oven. Hilton DoubleTree hotels provided the cookie dough(生面团). The makers of the oven did expect some difference in the baking time in space, but they were surprised that difference was so large.
Italian astronaut Luca Parmitano took charge of the baking experiment. He reported that the first cookie stayed in the oven for 25 minutes at 149℃. When it came out of the oven, it was seriously under-baked. For the next two cookies, Parmitano more than doubled the baking time. Those cookies came out better, but were still under-baked.
The fourth cookie stayed in the oven for two hours, after which Parmitano was able to report success. “I can’t tell you whether it’s cooked all the way or not, but it certainly doesn’t look like cookie dough anymore.” he reported to controllers back on Earth. For the fifth cookie. Parmitano turned the oven temperature up to 163℃ and baked it for 130 minutes. This time, he reported the best baking results.
The astronauts could smell the cookies when they removed them from the oven, except for the first. No one has tasted the space-traveling cookies just yet. Organizers of the experiment say additional testing needs to be carried out to determine whether they are safe to eat.
Mike Massimino, former NASA astronaut, said, “We have never been able to cook food from raw ingredients before, As we journey further away it is going to be harder to get things we need in space and food, for example, is one of the most important things.” Eating something other than dehydrated(脱水)or prepackaged food will be especially important as astronauts head back to the moon and on to Mars.

6 . Train travel can be a very fun experience. You can take in the beautiful scenery and have a relaxed travel experience without the trouble of air travel. Besides, trains are an environmentally friendly choice. Now, train travelers have an additional justification to go by rail. Deutsche Bahn, the national railway company, just cut the price of long-distance travel by 10 percent—a move which has drawn comparisons to the United Kingdom, where millions of people are now trying hard to deal with a 2.7% price increase.
This move, according to the company, came from the climate law passed by the government including a cut in the VAT—value added tax (增值税) -on train travel from 19 percent to 7 percent.
The new prices apply to trips over 50 kilometers, only if the passenger travels from one railway region into another one. Prices are also cut on special offers and additional services, such as fees for traveling with your bicycle.
Deutsche Bahn said, “We do not make any money from the tax cut, and are passing on all savings directly to ticket buyers.” According to Deutsche Bahn, this change is expected to bring in another 5 million passengers a year who’ll change to train traveling for the lower prices.
What actually causes it? Climate protection action. Decreasing the release of carbon from transportation is a key part of the 2015 Paris Climate Agreement and Germany is trying to meet its requirements to keep global wanning below 2℃.
In an effort to follow the new rules, Deutsche Bahn has planned on buying new trains by 2026 at a cost of $13.46 billion. Germany has already been greening its transportation. Hydrogen (氢) trains were introduced in Germany in 2018. The country is also testing power lines for eTrucks on the motorway.

| C．Germany’s actions to offer better travel experience. |
| D．Germany’s moves to offer environmentally friendly transportation. |
