Cars make our lives more convenient. But theycan also be a problem. For example, fossil fuel (化石燃料)cars mainly cause air pollution.

    To improve the environment, many countriesare developing electric vehicles (EVs,电动车).Among them, China is taking a leading role and has created the world's largestEV market.

    Last year, over 40 per cent of the 753,000EVs sold in the world were sold in China, more than twice as many as the numbersold in the United States.

    "Filling up a fossil fuel car with gas(汽油) is more expensive than charging (充电) an electric car," said Wu Hao, who bought an electric carthis year.

    However, there are still some problems. Itcan be hard to find charging piles (充电桩) andthe cars can't go far before being recharged.

    Some of these problems are being solved. In2014, China had 31,000 charging piles. Now China has the world's largest EVcharging network, with more than 450,000 charging piles in total.

    Developing EVs is one of many efforts thatChina has made to cut down pressure on its environment after the governmentpromised to stop increases in carbon dioxide emissions (二氧化碳排放量) by 2030.

    "As China goes, so will the world'scar industry," the Wall Street Journal said.

After {#blank#}6{#/blank#}(finish) his studies in MIT, Pei continued his studies at Harvard Graduate School of Design. During World War II, Pei took a break from his education. In 1944, he returned to Harvard {#blank#}7{#/blank#} got his master's degree（硕士学位）in architecture two years later. In 1955, Pei set up {#blank#}8{#/blank#}(he) own company, I.M.Pei & Associates. One of his {#blank#}9{#/blank#}(one) major projects（项目）was the Mile High Center in Denver, Colorado.

①Jiyou Village in Guizhou Province is famous for its ancient trees and beautiful folk songs. The village is full of Miao culture, and forests cover most of its land. Because of its rich culture, Jiyou Village was included in the List of China's Traditional Villages in August 2013.

②One of the most important events in Jiyou Village is the Bridge Worship Festival(祭桥节). It is celebrated on the second day of the second lunar month. During this festival, the Miao people take an active part in the joyful preparations, cooking traditional dishes, making wine, and practicing their traditional songs and dances.

③When the festival approaches, the village becomes lively, with villagers dressing up in colorful Miao clothes. Men play the lushing, a traditional musical instrument, while women carry baskets filled with delicious food and wine. The children, dressed in their best clothes, can hardly wait for the fun to begin.

④The highlight of the festival is the bridge worship ceremony(仪式). Villagers come together under the guidance of the elders to honor the bridge and celebrate their heritage(传统).

⑤Many tourists come to experience the traditional festival. During the daytime celebrations, the village square is filled with the happy music of the lushing as villagers and visitors dance together. Tourists take pictures and make videos to remember the special moments.

⑥As night falls, villagers and tourists gather around a bonfire(篝火) in the square. They laugh and chat while sharing stories and delicious food. It's a great time to make new friends and enjoy the warm atmosphere(气氛).

 Have you ever experienced the feeling of falling as you start to fall asleep? Sometimes you may wake up to this feeling. If so, don't worry. Many people have felt the same thing.

 In fact, the muscle twitches(肌肉抽搐) in the arms, legs or other parts of the body are called hypnic jerk(入睡抽动) or sleep starts. And they are very common. Up to 70 percent of people experience them sometimes, Huffing to Post reported. But what causes it?

 There are some theories(理论). Some scientists believe that the feeling of falling comes from the body relaxing itself, especially if the person is anxious or unable to get comfortable. As you' re going to sleep, your muscles become relaxed. But your brain stays awake. It misunderstands the relaxing of your muscles as a sign that you' re falling. The brain then jerks the body awake as if it's trying to protect you.

 Other scientists believe that different phase(时期) of sleep might cause hypnic jerks. When we sleep, we experience two phases: non-rapid eye movement(NREM,非快速眼动睡眠期) and rapid eye, movement(REM,快速眼动睡眠期). During REM, our heart rate can act irregularly. If the body experiences flashes(一瞬间) of REM while entering sleep, these irregularities could cause twitches.

 If you don't want to experience hypnic jerks, scientists have some suggestions. When you become deeply relaxed, you can learn how to reconnect your body with your brain slowly by moving your fingers and toes a little bit. Then start to move your head and open your eyes so that you can avoid the muscle twitches.

 But experts agree that hypnic jerks, though sometimes scary, are harmless. If it wakes you up, simply roll over and go back to sleep, But keep in mind: a caffeinated drink, exciting evening activities or stress may make hypnic jerks happen more often.
