1 . The butterfly, which is competitive swimming’s newest stroke (划水), was developed in the mid-1930s, but it wasn’t allowed in the Olympics until 1956. The story of the butterfly is a good illustration of how coaches and swimmers are constantly searching for ways to improve stroke efficiency.

During the 1920s, the Japanese Olympic coaches used underwater photography to research stroke mechanics, and their efforts paid off when Japanese competitors won five of the six men’s swimming gold medals at the 1932 Games in Los Angeles.     

It was a wake-up call to the rest of the swimming world, and one of the top US coaches – David Armbruster at the University of Iowa – began doing his own filming.

Armbruster was seeking to make the breaststroke faster. He knew that the action of bringing their arms forward underwater slowed breaststrokes down, so he came up with a method of bringing the arms forward over the water. The revised stroke (he kept the breaststroke kick) brought great improvements in speed.

The following year, Jack Sieg, an Iowa swimmer, developed a technique involving swimming on his side and beating his legs in unison (一致) similar to a fish tail. As Armbruster later explained in the book Weissmuller to Spitz: The History and Background of the Olympic Games: “Sieg tried the same action while swimming face down. Sieg synchronized his leg action with the butterfly arm action using two leg beats to each arm pull.” But the kick was ruled illegal because the legs moved in the vertical (垂直的) plane.

Within a few years, nearly every breaststroker was using this overarm butterfly action without the kick. The pure butterfly wasn’t legalized for some two decades, but at the 1956 Olympics in Melbourne ‘the fly’ became an official event.

4 . Yoga is an age-old practice that stretches the body and calms the mind. By performing a series of poses, called asanas, Yoga practitioners make themselves more flexible and relaxed. These results in lower blood pressure, a decrease in stress, and healthy muscles.     1     With poses ranging from simple to challenging, yoga gives your mind something to think about while you exercise.

Let's get started from the most basic pose --- Mountain Pose. Standing barefoot on an anti-slip mat, put your feet side by side so that the basis of your big toes are touching.     2     As you stand straight and down with your arms at your sides, feel the strength in your legs. Practice holding your head and neck in a straight line. Relax your shoulders. Breathe in and out, and focus on your breathing.

    3     This is a great way to loosen a tight back, neck or shoulders. Begin on all fours with your hands under your shoulders and your knees under your hips. Hold your spine（脊椎） and neck in a straight line. Then drop the head and neck toward your mat, pull your stomach muscles in tight, and round your back up towards the ceiling.     4     As you exhale, return to the center, then drop your belly toward the mat, and tilt your head back gently so that your eyes move up toward the ceiling. Feel your spine move more deeply into your body. Breathe in and out here.

    5     Gradually add more asanas to your practice. Before long you will notice a positive change in your post, your strengths, and your flexibility.

A．It can be hard to balance in this way.

B．Hold that pose and breathe in and out.

C．Then you can try out Cat to Cow Pose.

D．Perform these poses every day, if you can.

E．But beyond its health benefits, yogurt has a lot of fun.

F．If the stress hurts pull back and lie down slowly on the mat.

G．Stand comfortably and adjust your feet till they feel good against the mat.

5 . The United Nations Educational, Scientific and Cultural Organization (UNESCO) included on December 17, 2020 China's Tai Chi on the Representative List of the Intangible Cultural Heritage of Humanity. The decision was announced during the online meeting of the UNESCO Intergovernmental Committee for the Safeguarding of the Intangible Cultural Heritage held from December 14 to 19 in Kingston, capital of Jamaica.

“Born in the mid-17th century in a small village named Chenjiagou located in Central China's Henan province, Tai Chi is not only a kind of traditional Wushu integrated with slow movements and deep breathing, but is also deeply rooted in many areas of Chinese culture, such as medicine and philosophy,” Zhu Xianghua says, who is the son of the famous Tai Chi master Zhu Tiancai.

Although it has spread to more than 150 countries and regions, attracting more than 100 million people to practice, the idea that Tai Chi is for the elderly has stopped many young people practicing the ancient Wushu. They think of it as a slow exercise, which is specially made and better suited for their grandparents. Instead, many young people are turning to the Indian practice of yoga to relieve stress, which was placed on the UNESCO's List in 2019.

In order to promote Tai Chi, joint efforts have been made from individuals and the Chinese government in the last decades. Xi'an Jiaotong University requires students to learn Tai Chi. Wang Yunbing, a professor in the university's sports center, stressed that Tai Chi is not only good physical exercise-researchers from the American College of Rheumatology find that it can help manage several diseases but is also conned ted to ancient Chinese civilization. Since 2014, the World Tai Chi Championships have been held every two years by the International Wushu Federation. It provides a platform for communication and learning between the Tai Chi masters and Tai Chi lovers around the globe. In January 2020, Tai Chi became an official event in the 2026 Dakar Youth Olympic Games.

A．It originated from fast Kung Fu action.

B．It was born around the 1750s in a village.

C．It is related to other cultural fields of China.

A．They think it easier to practice yoga to keep fit.

B．The elderly stop young people practicing Tai Chi.

C．They consider Tai Chi is custom-built for old people.

D．Yoga was included in the world culture earlier than Tai Chi.

3. What is the main purpose of the last paragraph?
