2 . Baggy has become the first dog in the UK—and potentially the world—to join the fight against air pollution by recording pollutant levels near the ground.
Baggy wears a pollution monitor on her collar so she can take data measurements close to the ground. Her monitor has shown that air pollution levels are higher closer to ground level, which has helped highlight concerns that babies and young kids may be at higher risk of developing lung problems.
Conventional air pollution monitors are normally fixed on lampposts at about nine feet in the air. However, since Baggy stands at about the same height as a child in a pushchair（婴儿车）, she frequently records pollution levels which are much higher than the data gathered by the Environment A gency.
The doggy data research was the idea of Baggy's 13-year-old owner Tom Hunt and his dad Matt. The English youngster noticed that pollution levels are around two-thirds higher close to the ground than they are in the air at the height where they are recorded by the agency. Tom has since reported the shocking findings to the government in an attempt to emphasise that babies are at higher risk of developing asthma（哮喘）.
Matt Hunt said he was "very proud" of his son because “when the boy gets an idea, he keeps his head down and gets on with it, and he really does want to do some good and stop young kids from getting asthma."
“Tom built up a passion for environmental protection at a very early age," Matt added. “He became very interested in gadgets（小装置）. About one year ago, he got this new piece of tech which is like a test tube. One Sunday afternoon, we went out to do some monitoring, and he said, why don't we put it on Baggy's collar and let her monitor the pollution？'So we did it."
Tom said, "Most of the time, Baggy is just like any other dog. But for the rest of the time she is a super dog, and we are all really proud of her."

4 . Tonal languages use pitch (音调) to distinguish words that otherwise might sound the same. In Mandarin, for instance, mă means horse whereas mã means mother. Nontonal languages like Spanish sometimes include pitch changes to suggest emotion, for example, but not to change a word’s meaning.
As a Mandarin speaker and musician, Jingxuan Liu wondered about the crossover (融合) between language and music. While studying at Duke University, Liu helped analyze the musical abilities of nearly half a million people from 203 countries. Her colleagues had launched an online game in which participants completed several musical tasks, including identifying matching melodies at different pitches and finding beat tracks that fit songs’ rhythms.
On average, native speakers of the 19 represented tonal languages were better at the melody task compared with speakers of 29 nontonal languages. And the effect wasn’t small a tonal first language strengthened melodic understanding by about half the amount that music lessons did, which was also surveyed. But tonal languages speakers tended to be worse at the rhythm task.
Humans must be choosy about what they pay attention to. Pitch patterns are quite important in tonal languages, which might explain the balancing act in music. “You’ve got a finite resource of attention, and you’ve got to divide up that somehow,” says study coauthor Courtney Hilton, a scientist at the University of Auckland in New Zealand.
Prior research on language and music often compared just two tongues, usually English and Mandarin. But other cultural influences, such as Eastern and Western music styles, could have affected results. By examining a wide range of people, the new study included languages never estimated in this way and reached more generalizable conclusion.
“Our result here is showing that the language someone speaks which is an important part of culture — also shapes cognition,” Hilton says.

| B．To learn about different people’s musical abilities. |
| C．To confirm the role of music in people’s language learning. |

| A．Finding beat tracks. | B．Suggesting emotion. |
| C．Distinguishing word meanings. | D．Figuring out matching melodies. |

5 . China is a colorful country with amazing places and cultures. In this blog, we will introduce five most attractive places that you can’t miss if you are planning to go for a travel in China!
Beijing
Beijing, the capital of China for over 850 years, is the first choice for many travellers. A perfect combination of classic elegance and modernity, it is the best Chinese destination to give you a better understanding of the country. You can wander around the Forbidden City to feel the dignity of the city; or you can walk along the criss-crossing hutongs and enjoy yourself in everyday local life.
Xi’an
If you want to feel the history of China over the past 1,000 years, you can go to Beijing; however, if you want to experience the 5,000 years’ history of this ancient, oriental land, Xi’an is the best travel destination in China. As one of the four major capitals of ancient civilisation (together with Athens, Cairo, and Rome), Xi’an is the home of Chinese civilisation. The Silk Road starts from here, stretching through West China to the Mediterranean.
Guilin
Guilin, a peaceful city lying in the hilly south-western area of the country, is among the top Chinese destinations for its extraordinary natural scenery. The unique karst landscape with its four features, namely green hills, clear water, fantastic caves, and oddly-shaped rocks, makes it a famous tourist attraction.
Chengdu
Visiting the lovely giant pandas must be on everyone’s to-do list when planning a tour of the best Chinese destinations. Many cities have zoos with space for pandas, but the best place to get close to them is Chengdu for sure! Visiting Chengdu is also a treat for food lovers. Jin li Street is a great place to have a taste of well-known Sichuan food. Besides, you can also enjoy the comfortable atmosphere.

8 . When a leafy plant is under attack, it doesn’t sit quietly. Back in 1983, two scientists, Jack Schultz and Ian Baldwin, reported that young maple trees getting bitten by insects send out a particular smell that neighboring plants can get. These chemicals come from the injured parts of the plant and seem to be an alarm. What the plants pump through the air is a mixture of chemicals known as volatile organic compounds, VOCs for short.
Scientists have found that all kinds of plants give out VOCs when being attacked. It’s a plant’s way of crying out. But is anyone listening? Apparently. Because we can watch the neighbours react.
Some plants pump out smelly chemicals to keep insects away. But others do double duty. They pump out perfumes designed to attract different insects who are natural enemies to the attackers. Once they arrive, the tables are turned. The attacker who was lunching now becomes lunch.
In study after study, it appears that these chemical conversations help the neighbors .The damage is usually more serious on the first plant, but the neighbors, relatively speaking, stay safer because they heard the alarm and knew what to do.
Does this mean that plants talk to each other? Scientists don’t know. Maybe the first plant just made a cry of pain or was sending a message to its own branches, and so, in effect, was talking to itself. Perhaps the neighbors just happened to “overhear” the cry. So information was exchanged, but it wasn’t a true, intentional back and forth. Charles Darwin, over 150 years ago, imagined a world far busier, noisier and more intimate (亲密的) than the world we can see and hear. Our senses are weak. There’s a whole lot going on.

9 . A fourth color might be added to traffic lights to better realize the potential of self-driving vehicles, as stated in a recent paper by researchers at North Carolina State University in the US.
Autonomous vehicles can do more than just drive-they are able to sense their surroundings and upload information. A shared network gives orders to stop at a crossing based on traffic conditions.
The added white lights would be used to signal to human drivers that autonomous vehicles are managing the upcoming traffic flow intelligently. Drivers don’t have to check the traditional lights if the white one is on. “The white lights will tell human drivers to simply follow the car in front of them,” one of the study authors Ali Hajbabaie told the university’s website.
Simulated (模拟的) models showed that autonomous vehicles were able to improve traffic flow on their own. Introducing the white light also has a positive effect on reducing fuel consumption. The higher the percentage of autonomous vehicles at a crossing, the faster the traffic moves, reducing about 40 to 99 percent of the total delay time.
What kind of infrastructure (基础设施) is needed as self-driving technology thrives? In an interview with China Surveying and Mapping magazine, Liu Jingnan at the Chinese Academy of Engineering shared his answers.
To begin with, the vehicle’s network that collects data about the environment and shares the data with other vehicles needs to be intelligent. High-precision maps are needed for autonomous vehicles to plan routes in detail. They can provide both updated information on traditional maps and real-time changes, such as accidents.
For example, when driving around a curve, the navigation (导航) system in the vehicle needs to calculate the safe speed based on the map’s information. And if the area is foggy, the network has to alarm the other cars to slow down.
Other elements on the road need to be upgraded too. For example, road markings should be precise and readable for machines. Sensors should be built on sidewalks and roads to allow vehicles to predict potentially dangerous situations.
1. What is the purpose of adding a white light to traffic lights?| A．To signal to self-driving cars when to stop. |
| B．To help driverless cars assess traffic conditions. |
