When the news came that the 2022 Winter Olympics would be hold in China, I felt very thrilled. It struck to me how I learned skating when I was a child. At 7, I began to go crazy about skating, like all my friend. At the beginning, it extremely tough for me to keep my balance. I always fall over on the ground, as the result of which I thought I had no gift for skating. So I gradually lost confidence and became impatient. The more impatient I was, the more terrible I did. I was about to give up while my father came to my assistance. Encouraged by her, I restored confidence and stood up again. As I practiced skating, he always created a relaxed atmosphere and put forward some specific suggestions. Eventually, I made it.

Tai Chi is on the rise as more and more people discover the health benefits that come from regular practice. 1. It's also a relaxing exercise that calms the mind while it energizes and strengthens the body. Many Westerners love Tai Chi because it provides a low-impact (低强度) workout that strengthens the belly and thigh muscles without putting any tension on the joints.
Tai Chi is quite easy to learn. Many recreation centers and community groups offer classes, sometimes in parks and other public places. 2. Wear loose-fitting, comfortable clothing when you go to class, and tennis shoes or shoes you don't mind standing and moving in.
One of the major benefits of Tai Chi is that it's a sport you can practice for life. 3. The strengthening and balance moves are hugely beneficial to their continued mobility. Also, the slow pace of Tai Chi makes it a great stress-reliever. As you focus on your breathing and posture (姿势), your mind can clear itself of its worries, and that does your whole body good.
4. All you need is your own body and enough room to stand in. You can do Tai Chi on a mountaintop, in the desert, on an ocean beach, or in the middle of a forest. 5. And it’s a lot of fun. So next time you see someone doing Tai Chi, ask them about it. They just might offer to teach you the forms of this fascinating sport.
A.It's a perfect outdoor activity.
B.Finally, you’ll keep a low center of gravity.
C.Best of all, Tai Chi can be performed anywhere.
D.Often these classes are free and open to anyone who shows up.
E.It's the focus on energy that sets Tai Chi apart from other sports.
F.With its gentle movements and focus on forms, Tai Chi is more than just a sport.
G.In China, many elderly people continue to do Tai Chi well into their eighties and nineties.
Blue Planet II's latest episode (情节) focuses on how plastic is having a destructive effect on the ocean and slowly poisoning our sea creatures. Researchers recently also found that sea creatures living in the deepest place on Earth, the Mariana Trench, have plastic in their stomachs. Indeed, oceans are drowning in plastic.
Though it seems that the world couldn't possibly function without plastics, plastics are a remarkably recent invention. The first plastic bags were introduced in the 1950s, the same decade that plastic packaging began gaining popularity in the United States. This growth has happened so fast that science is still catching up with the change. Plastics pollution research, for instance, is still a very early science.
We put all these plastics into the environment, but we still don't really know what the outcomes are going to be. What we do know, though, is disturbing. Ocean plastic is estimated to kill millions of marine animals every year. Nearly 700 species, including endangered ones, are known to have been affected by it. One in three leatherback turtles, which often mistake plastic bags for jellyfish, have been found with plastic in their bellies. Ninety percent of seabirds are now eating plastics on a regular basis. By 2050, that figure is expected to rise to 100 percent.
And it's not just wildlife that is threatened by the plastics in our seas. Humans are consuming plastics through the seafood we eat. I could understand why some people see ocean plastic as a disaster, worth mentioning in the same breath as climate change. But ocean plastic is not as complicated as climate change. There are no ocean trash deniers (否认者), at least so far. To do something about it, we don't have to remake our planet energy system.
This is not a problem where we don' t know what the solution is. We know how to pick up garbage. Anyone can do it. We know how to deal with it. We know how to recycle. We can all start by thinking twice before we use single-use plastic products. Things that may seem ordinary, like using a reusable bottle or a reusable bag-when taken collectively, these choices really do make a difference.
1.Why is plastics pollution research still a very early science?
A.The plastics pollution research is too difficult.
B.Plastics have produced less pollution than coal.
C.Plastics have gained popularity too fast for science to catch up.
D.The world couldn't possibly function without plastics.
2.How did the author support his opinion in Paragraph 3?
A.By citing quotes from leading experts. B.By making a comparison and contrast.
C.By listing examples from his own experience. D.By presenting solid statistics.
3.What does the author intend to tell us in the last paragraph?
A.We reap what we sow. B.The shortest answer is doing.
C.All things are difficult before they are easy. D.Actions speak louder than words.
4.What is the main idea of the passage?
A.The oceans become choked with plastic. B.Ocean plastic is a global issue.
C.Blue Planet II has left viewers heartbroken. D.Plastics gain in popularity all over the world.
