2 . Screen time before bedtime may leave people feeling sleepy in the morning. Cell phones, computers and TVs emit (发出) blue light. And exposure to that bluish light during the two hours before bed can keep us from getting a good night’s rest, a new study finds. It cuts down on the length of people’s sleep. It also leaves them feeling tired in the morning and can disrupt the body clock. Data shows that this blue light tends to make us more alert at night, making it harder to get all the rest we need.
Green and his team surveyed 19 people — all in their 20s — for a sleep study. All spent two hours on a computer right before bedtime. But they didn’t all experience the same light exposure. Looking at screens that gave off intense blue light cut someone’s sleep by about 16 minutes, compared to when they had used screens with red light. Those exposed to blue light also woke up more often at night than if they had been exposed to red light.
“The normal blue light emissions from the computer screen also affect how much melatonin (褪黑素) each volunteer makes. It is released into our blood around 9 p.m. When our bodies make less melatonin, we may still feel too alert at bedtime to fall asleep when the body is tired. And body temperature won’t drop as expected after we use devices emitting lots of blue light. Using screens before bed damages the body’s biological clock,” Green says. “More and more kids are using screens nowadays. Sleep is important, especially during the first few years of life when ‘neural plasticity’ (神经可塑性) is at its greatest. Their brains are still developing the ability to learn and pay attention. That makes the new results worrisome,” Green says.
Rahman says that the new work makes a good point about how blue light from screens can be bad for our bodies. However, he points out, the light in this study is extremely bright. It is far brighter than what a normal computer, tablet or TV will emit. Still, Rahman says the results remind us to think about how we should use screens before bed.

3 . The ban (禁令) on petrol and diesel (柴油) cars due in 2030 may have to be scrapped because of a lack of charging points for electric vehicles, industry experts warn. The Government wants to outlaw the sale of new fuel models in order to go green and cut pollution. But industry figures suggest this may not be possible. Analysis highlights a lack of high-powered electric vehicle (EV) chargers at motorway service stations.
The Government has promised that every motorway service area has at least six rapid chargers by the end of 2023. But only 27 out of 119 motorway services in England meet that target. This will fuel “charge point anxiety”, which experts warn is preventing drivers from buying electric cars in case they cannot power them up while on journeys. Lisa Watson, director of sales at Close Brothers Motor Finance, said: “The UK is set to fall significantly short of its charging point targets.”
This could have a far-reaching effect on consumer uptake of alternative fuel vehicles. If more isn’t done to improve charging infrastructure (基础设施), the 2030 ban on new petrol and diesel vehicles will seem an increasingly tough task. Rapid charge points can add about 100 miles of range to an EV in 35 minutes and are seen as crucial to encouraging more motorists who use their cars for long journeys to make the switch to electric.
There are also concerns over the distribution of public charging points.While Westminster has 2,196, there are just 1,593 across Liverpool, Manchester, Newcastle upon Tyne, Leeds, Sheffield and Birmingham. The Society of Motor Manufacturers and Traders expects plug-in battery electric vehicles to account for 18.4% of car sales this year and 22.6% next year-down from previous forecasts of 19.7% and 23.3%.
A government spokesman said, “The importance of ensuring high-powered charging is readily available up and down our motorway network can’t be highlighted enough. A lack of charging facilities is becoming one of the most widely quoted reasons for drivers not going electric.”

A.Charge point anxiety. | B.Bad motorway service. |
C.The imperfection of law. | D.Too slow charging speed. |

B.They can lead to an increase in drivers. |
C.They will boost people’s confidence in EVs. |
D.They enable an EV to run 35 minutes. |
A.Sufficient high-powered charging must be provided. |
B.The excuse for drivers not to buy EVs is unacceptable. |
C.There is too much focus on high-powered charging. |
D.The lack of charging devices will continue for a long time. |
This is a true story of my grandfather James. In the 1930s, Grandpa was a school kid and took a part-time job in a theater. One day, during a break when the audience were going to the bathroom, he was shocked to see three very huge rats which crossed the aisles (过道) and went under the seats. Grandpa feared the audience would be hurt.
When the movie was over, Grandpa told the manager what he saw. The manager was anxious, and said they couldn’t use poisons to drive the rats away. Grandpa suggested putting cats in the theater at night when it was closed. The manager agreed and gave grandpa the task of putting the cats in the theater at night, but grandpa had to be there in the morning to remove the cats and any dead rat that might be around.
The next day, grandpa found two cats. At the end of the night when the movie was over, he brought the cats into the theater as “night guards”. Then, he left and headed home, excitedly thinking about how many dead rats there would be when he went to the theater in the morning.
The next morning, grandpa hurried to the theater to take care of the cats and all of those dead rats before he went to school. After reaching the theater, he opened the front door, to his surprise, the two cats rushed out of the door and down the street at once. Confused, grandpa entered the theater and turned on the light. To his surprise, he couldn’t find one dead rat.
Soon, grandpa and the manager found out that the rats were so big that the cats were actually scared of them. Grandpa wondered how to deal with the problem. When grandpa got home from school that day, he told his parents what had happened. They laughed and told him that the best way was to get a Rat Terrier dog. They said it’s a type of dog that is good at killing rats. Although grandpa doubted it, he decided to have a try.

8 . Favored by many internet influencers, the city of Zibo, once a sleepy industrial city, has gone viral on Chinese social media platforms. The topic Zibo “barbecue” on Douyin, the Chinese version of TikTok, was played 4.96 billion times since the city stormed the Internet for over a month. On 29 April, Zibo Railway Station saw a record 87,000 train trips to and from the station, according to Chinese news website Caixin.
Local authorities in Zibo have been quick to respond to the sudden flow of visitors. A barbecue zone that can accommodate 10,000 people, featuring live band performances, was built overnight. Volunteers have been dispatched to the railway station to offer advice and recommendations to tourists. Designated (指定的) buses and trains bring tourists to and from the hottest barbecue spots. The government has even threatened to punish profiteering hotels who raise prices by more than 50% .
What makes Zibo barbecue so special is that it does offer a distinctive (独特的) dining experience. The skewers (烤串) are 70-80 percent cooked before they are brought to the table, where diners can finish cooking them on their own stoves, offering an immersive dining experience.
Zibo’s low prices are also appealing. Many college students in Shandong have made concrete plans to enjoy Zibo barbecue at the least cost, and traveling back and forth by train for only 200 yuan ($29.1). So what better way to attract adventurous, hungry college students with a tight budget other than “tasty barbecue that makes you full for only 50 yuan!”
The locals seem happy enough about the arrival of visitors and shy away from hot spots to make space for outsiders, saying they are proud that their hometown has gained nationwide fame.
