Maybe many girls don’t have the habit of applying base cream before powder makeup, at least I was like this a year ago. One is because I am afraid of trouble, I can still apply foundation and make-up without it; the other is because I heard that the barrier cream is not absorbed by the skin, it will affect the skin’s breathability, and it will increase the burden on the skin… Later, it was the same as 　　me The “smelly” cousin told me that all these are our prejudices against sunscreen. Whether it’s good or not, the only way to know is to try it yourself. Today, more than a…

　　No matter which field, it is not easy to figure out its complete context. Because you can’t separate completely independent individuals from history, they are interdependent, inherent and natural. As far as human history is concerned, the invention of the train was a ground-breaking event, and then the evolution of steam locomotives, diesel locomotives, electric locomotives, and high-speed EMUs continued with each other. Keep up with the ever-changing times one after another. 　　Looking back, the development of railways has a history of only two hundred years. Only by interpreting history, rather than controlling history, and tracing the past along its journey, can we understand the context of railway development. Today,…

　　”If you want to write about the wind, you can’t just write about the wind. You have to write about the curvature of the treetops, the ripples on the lake, the sound of the leaves whirling and the path they landed on…” The advertisement copy of this composition writing class seems to be out It became popular, and it was even made into a song, a catchphrase, an imitation copy that everyone competed for, and even a standard for writing, especially for students. 　　I always feel that this kind of “If you want to write, you can’t write” is a bad advertising routine, especially for elementary school students, it is…

　　Plastic, one of the greatest inventions of mankind, imagines how difficult and expensive our life would be without plastic. Plastic is actually a general term for man-made plastic chemical products. In the big family of plastics, nylon is the earliest chemical synthetic fiber product. 　　After the birth of nylon, it completely changed people’s habit of using fabrics, allowing clothing and fashion to evolve in various forms, and practical and beautiful clothing also flew into the homes of ordinary people. In our impression today, flexible nylon is the darling of the women’s world, but in fact its application in military and industry has also set off a storm of the times.…

　　I went to Malaysia with my friends for vacation. We lived in a remote seaside resort with not many tourists, so that we could better experience the charm of the tropical seaside jungle. 　　On a sunny afternoon, my friend and I were basking in the sun and chatting on the beach. Suddenly, there was a muffled sound behind us. Looking back, it turned out that a big coconut fell on the beach. It was fresh, and my friend and I ran over immediately Look carefully, when we were approaching the coconut, my friend suddenly screamed: “There is a spider! It’s a big one!” I looked on the beach, and sure…

　　Before I knew it, my memory was getting worse and worse. I can’t remember the 6-digit SMS verification code unless I read it silently in my heart. Often when I open the refrigerator door, I forget what I was going to take. Looking for things before going out is to confirm the ultimate collapse of memory-where did the mobile phone, keys, glasses case, tissue, and wallet that I just picked up go, and I had to spend a long time in the room, looking for it. 　　When these moments of frustration accumulate, people will mutter in their hearts: It’s over, my brain is so hard, is this a sign of…

Can wearing a mask for a long time cause pulmonary nodules to increase? 　　Some people say that the melt-blown cloth in the middle layer of the mask is made of petroleum products, and the fine particles in it will enter the human lungs through the respiratory tract, and long-term wearing can cause human lung nodules to increase. Is it really? In fact, wearing a mask during the normal use period will not produce fine particles, nor will it cause the increase of human lung nodules. In addition to textile materials such as cotton, wool, hemp, silk, and regenerated cellulose fibers, many synthetic fibers, including meltblown cloth, are made from petroleum-based…
