【推荐1】It is harder to get your kids to read a book now with tablets and smartphones being so prevalent (盛行的). Actually, you don’t have to force your kids into reading but rather encourage them to find enjoyment in it.

    1     You can of course say no to any books that seem inappropriate, but kids will be more likely to read more if they are enjoying what they’re reading and they feel like they have a say in the book that they’re reading.

Reading is usually a solitary (独自的) activity.     2     That’s why you can read books together. When you’re reading together, ask questions like ”What did you notice on that page?” or “Did you see that... ?” to make sure they are paying attention.     3     Doing voices is a great way, which can always make kids laugh. Do make reading together a cuddle (依偎) moment. It can’t be a rushed activity. Take a breath and let the day go, and then move into story time.     4    

Getting kids into books can take many different forms. Traditional books are great, but have you thought about getting them into stories via audiobooks (有声读物)?     5     And once they’re excited to hear the rest of the story, continue at home, whether it’s with a paper version of the book or more audiobooks. Kids can also listen on their own with headphones if they prefer to listen by themselves.

But, should average summer air temperatures rise by a few degrees, some of those clear waters could turn a cloudy green or brown, the Learn reports in the Sept. 28 Geophysical Research Letters.

The changing colors could change how people use those waters and offer clues about the stability of lake ecosystems. Compared with blue lakes, green or brown lakes have more algae (藻类) and organic matter, says Xiao Yang, a hydrologist (水文专家) at Southern Methodist University.

Lakes in places with average summer air temperatures that were below 19° Celsius were more likely to be blue than lakes with warmer summers. That’s because warmer water helps algae bloom more, which changes the properties of the water.

Yang and colleagues used satellite photos from 2013 to 2020 to analyze the color of more than 85,000 lakes around the world. Because storms and seasons can temporarily affect a lake’s color, the researchers focused on the most frequent color observed for each lake over the seven-year period. The researchers also created an interactive online map that can be used to explore the colors of these lakes. The approach is “super cool,” the researchers say. These satellite data are “just so powerful.”

If some lakes do become less blue, people will probably lose some of the resources they have come to value, O’Reilly says, who is an ecologist at Illinois State University. Lakes are often used for drinking water, food or recreation. If the water has more algae, it could be unappealing for play or more costly to clean for drinking. But the color changes wouldn’t necessarily mean that the lakes are any less healthy. “Humans don’t value lots of algae in a lake, but if you’re a certain type of fish species, you might be like ‘this is great’” O’Reilly says.

【推荐2】Rock ‘n’ roll is a style of music that developed in the 1950s, mainly out of an originally African American genre called rhythm and blues, as well as gospel and even country music. Usually played with electric guitars, drums, and often saxophones and pianos, rock ‘n’ roll is faster than rhythm and blues, and is known for its strong beat, simple tunes and energy.

One of the great early Black American rock ‘n’ roll stars was the songwriter and guitarist Chuck Berry. Berry was known for the energy of his performances, and songs like “Johnny Be Goode” and “Roll Over Beethoven” made him famous as the “father of rock ‘n’ roll.” Another early Black American rock ‘n’ roller, who was known for his wild singing and piano playing, was Little Richard, who had hits with songs like “Tutti Frutti” and “Long Tall Sally.” Some people called him the “architect of rock ‘n’ roll”.

Young people loved this new rebellious style of music, and soon white musicians were recording rock ‘n’ roll songs too. Some popular early stars were Buddy Holly with his song “That’ll Be the Day”, and Jerry Lee Lewis with “Great Balls of Fire” However, the biggest star was Elvis Presley. Elvis was handsome, he sounded more like the Black rock ‘n’ roll singers, and he had a dance style that excited young people-and shocked their parents! With songs like “Hound Dog” and “Jailhouse Rock”, he became known as the “king of rock ‘n’ roll”.

In the early 1960s, a British band called the Beatles began their career singing the rock ‘n’ roll songs of stars like Chuck Berry and Little Richard. Rock ‘n’ roll had become popular across the world, and by the mid-1960s it had grown into a broader, more international style of music called simply “rock”.
