Why do parents have such a difficult time to communicate openly and honestly with their teens? For this, there are many reasons but most of them stem from not being able to properly understand their teens. It is a dangerous gap because parents will have to communicate with their teens about a wide variety of issues during the most important years of their lives. Thus, parents must know how to communicate openly and honestly with their teens.

    Here are a few tips to make communication easier between parents and teenagers.

    1）Try not to talk down to your teens. Make them feel as if their views really matter, which not only helps your discussions with your teen but bring you closer to him.

    2）Imagine what it would be like to be a teen. Try to remember some of the negative feelings you experienced as a teenager and apply it to your teen's situation.

    3）Never make negative remarks to your teen about what he has said or done.

    4）Remember how much courage it would have taken for your teen to come and talk to you about his personal issues. So listen respectfully.

    5）Don't ignore your teen's feelings because it is usually a cry for help. For instance, if your teen is unusually angry, it may be time to spend a bit of quality time with your teen to determine what is wrong and where he is coming from.

    It is, therefore, necessary for parents to strive to keep lines of communication open at all times with their teens. Try to remember what it was like to be a teenager and how vulnerable（脆弱的）you felt. Then you will be well on your way to help your teen communicate more openly and honestly.

    The most exciting storms are the ones with flashes of lightning.Unfortunately,those are scarce,unless you are near the Catatumbo River in Northwestern Venezuela.Here,nature's grandest sound and light show is often seen, because it happens about 160 nights a year.And it lasts for as long as 10 hours at a time.And unlike other lightning storms that cause just one or two flashes,this one is with as many as 280 per hour.It is the highest in the world. Besides,each one of them is so powerful that each can power every light bulb in South America.Not surprisingly,they can be seen for almost 250 miles.Fishermen and sailors often use them to guide them across the waters during dark nights.

    What's even more surprising is that the lightning has been happening above the same spot where the Catatumbo River meets Lake Maracaibo for thousands of years.The best part is that the show is different every night.That's because the color of the lightning changes,depending on the amount of water in the atmosphere.On dry nights,the lightning appears white.When the air is not dry,it helps split up the bright light into red,orange and even purple.

    Strangely enough,though this has been going on for centuries,scientists have still not been able to figure out the cause of this phenomenon.Some say that the storms are the result of the interaction of the area's unusual topography（地貌）,wind and heat.Others,however,believe that the storms are caused by a kind of gas in the area.The locals simply think that it is the "spirit of Catatumbo" that lights up the night sky.

    Shyness is the cause of much unhappiness for a great many people. Shy people are anxious and self-conscious; that is, they are concerned with their own appearance and actions too much. Negative thoughts are constantly occurring in their minds: What kind of impression am I making? Do they like me? Do I sound stupid? Am I wearing unattractive clothes?

    It is obvious that such uncomfortable feelings must affect people unfavorably. A person's self-concept is reflected in the way he or she behaves and the way a person behaves affects other people's reactions. In general, the way people think about themselves has a deep effect on all areas of their lives.

    Shy people, who have low respect, are likely to be passive and easily influenced by others. They need faith that they are doing "the right thing". Shy people are very sensitive to criticism. It makes them feel inferior（自卑）.They also find it difficult to be pleased by praises because they believe they are unworthy of praise. A shy person may respond to a praise with a statement like this one: "You're just saying that to make me feel good, I know it's not true.” It is clear that, while self-awareness is a healthy quality, overdoing it is harmful.

    Can shyness be completely got rid of, or at least reduced? Fortunately, people can overcome shyness with determination since shyness goes hand in hand with lack of self respect. It is important for people to accept their weakness as well as their strengths. Each one of us has his or her own characteristics. We are interested in our own personal ways. The better we understand ourselves, the easier it becomes to live up to our chances for a rich and successful life.

    Eating is best when it's a social activity. Think of the meal a family enjoys in the evening when everyone's together after work or school, or the big get-togethers over food at Spring Festival. But now, in the age of the Internet and social media, anyone with an Internet connection can enjoy a social eating event.

    Mukbang-a South Korean phrase meaning “eating broadcast”-is an unusual food fanaticism that's sweeping the country. This is a meal where only one person gets to eat, while many viewers watch live shows of hosts eating large quantities of food. They leave comments on the dishes the host is taking, and the host responds to them live.

    So why have people taken to this unusual new food trend(趋势)? Jeff Yang, an Asian-American cultural critic, thinks that it's down to “the loneliness of unmarried or uncoupled South Koreans”. He believes that eating on your own can be hard in a country like South Korea, where social eating is such a long tradition. However, Mukbang gives people the feeling that they are part of something larger, it seems.

    Millions of people have trouble with food. Either they eat too much of it, or too little. Some say that the popularity of Mukbang helps people with these disorders. Those who always eat too much and put on weight can watch Mukbang live shows to satisfy their appetite (胃口). And those who don't eat enough can build their appetite by watching delicious food being eaten.

    Even though Mukbang is a South Korean phenomenon, it's also taken off in the US. But unlike South Koreans who sit down to enjoy noodles and kimchi (泡菜), Americans enjoy their own native dishes. This means that viewers of US Mukbang live shows will see locals stuffing themselves with hamburgers, fries and ice cream.

    The Frick Collection (5th Avenue and E. 70th Street)

    Many art lovers would rather visit this small art gallery than any other in New York.

A 293-million-mile journey of the NASA Perseverance rover (探测器) to Mars: ended successfully on February 18, 2021, with a picture-perfect landing inside the Jezero Crater. The car-sized, six-wheeled rover, nicknamed Percy is the US space agency's biggest and most advanced explorer to date. Its primary mission is to search for signs of ancient microbial (微生物的) life on Mars.

Landing on Mars is extremely tricky. The Red Planet's gravitational pull causes approaching spacecraft to go faster to high speeds, while its thin atmosphere-just 1 percent that of Earth's-does little to help slow it down as it approaches the surface.

The scientists had to reduce Percy's 12,000 mph speed to a safe landing speed of less than five mph-in just six and a half minutes. The target entry angle also had to be a precise 12 degrees-any steeper, and the spacecraft would burn up; any flatter, and it would get lost in space. It is no wonder that the final approach is often referred to as the "seven minutes of terror. "

Upon attaining a manageable speed, Percy briefly flew over the Martian surface to seek out the perfect landing spot. Its complex map-reading system rapidly scanned the area and matched it with maps in its database to find the best location.

The NASA scientists will spend the next two months testing Percy's scientific instruments. Once ready, the rover will begin to carry out its mission.

"Perseverance is the smartest robot ever made, but confirming that microbial life once existed carries an unusually large burden of proof," said Lori Glaze, director of NASA's Planetary Science Division. "While we'll learn a lot with the great instruments we have aboard the rover, it may very well require the far more well-equipped laboratories and delicate instruments back here on Earth to tell us whether our samples (样本) carry evidence that Mars once harbored life.
