Today I’ll talk about how to improve your pronunciation. Language researchers say pronunciation and fluency (流利度) are the biggest difficulties, followed by grammar and listening. However, most people don’t regard pronunciation as a very important part of communication skills. They pay more attention to vocabulary. One reason is that most people don’t even realize their mispronunciations. So it’s important to find out the words you mispronounce first. You should listen to experts those who make fewer pronunciation mistakes. When listening to them, you should pay attention to words that sound strange, because you may pronounce the same words differently. When you meet such words, look up their right pronunciations in a dictionary. You can also search for words that are difficult to pronounce and make a list (清单) of them. At last, read aloud. Now you’ve got the correct pronunciations of the words. It’s time to practice reading them out every day.

【推荐1】“I’ll finish my homework before playing video games.”
“Your dress looks beautiful.”
“I won’t spend all the money on snacks.”
All lies! Most of us have told a lie at one time or another. However, scientists found that lying can harm your brain(大脑). It may stop you from doing other important tasks.
When you tell the truth, your brain doesn’t have to do any extra (额外的) work. But lying takes much more work.
Imagine you’re late to class. The teacher asks why and you decide to lie. So you say: “I picked up a book from the library.” Your teacher asks, “The book I assigned (布置) last time?” Then you must decide how to answer the question. If you say yes, your brain works a lot more to keep the lie from falling apart.
You just gave your brain a lot of extra work. An area called the prefrontal cortex (前额皮质) does the work. It’s the part in charge of short memory. That area also takes care of planning, problem-solving and self-control.
Using too much brainpower to lie means there’s less available for other things-like solving math problems. Lying is even harder for young people. The prefrontal cortex is not fully developed until age 25. So when young people are busy with lying, they’ll have a harder time doing other things, like making study plans or eating a healthy diet. So think twice before lying next time!

【推荐2】With her eyes feeling increasingly tired and her vision blurry, 16-year-old Sun Run went to the hospital with her parents in January. She was shocked when she found out that her eyesight dropped from 5.0 to 4.6 in only a semester. “A few of my friends have had the same experience lately,” Sun said.
In fact, poor eyesight among Chinese primary and high school students rose from 59.2 percent to 70.6 percent in the first six months of 2020, according to the Ministry of Education.
To protect students’ eyesight, the Chinese government has worked out new requirements for school supplies and equipment that will take effect on March 1, 2022. For example, according to the requirements, the size of text in students’ textbooks should be no smaller than nine-point.
Teachers should also avoid using projectors or other multimedia equipment that are too bright, Beijing Daily reported.
There are also requirements for desk and classroom lights. For example, these lights should give off as little blue light as possible.
Blue light is bad for our eyes, as it can kill the photoreceptor cells(感光细胞) we need for vision, according to Harvard Medical School. Many of the electronic devices we use every day, including our phones and computer screens, give off blue light.
Chinese government has also taken other steps to protect students’ eyesight in China. In May 2020, the National Health Commission urged schools to make sure that students have at least two hours of outdoor activity a day.
