Electricity is an important part in our life. We can't see or touch it, but it is all around us. Our life will be terrible without electricity. But some people don't know that everyone should save electricity. When it is not completely dark, many street lamps (路灯) light up early in some streets. Some people don't turn off the lights when they leave the room. Some people are sleeping with the lights on. They are all wrong. Here I make somesuggestions about stopping these things:

    *Turn on the street lamps on time. We light them from 7：00 p. m.～5：30 a. m. in summer, and from 5：30 p. m.~6：00 a. m. in winter.

    *If some small areas are very dark, just turn on a few lights.

    *The distance (距离) between street lights can be 50～60 meters. It can save electricity and money.

    *If there are some activities, such as fairs, we can make the lights bright；if there is no activity, lights needn't be too bright.

    Ask people to save electricity through TV shows, newspapers, and so on.

    Electricity is a valuable resource (资源). It helps us live well and conveniently. We should take action to save it at once!

    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.

    Have you ever considered starting a fitness program? Since exercise can reduce the risk of diseases, improve balance, help lose weight, better sleep habits and even make you confident, you should start a fitness program in the following steps.

    Test your fitness level

How many meters can you walk or run in one minute? How much time does it take you to swim 50 meters? What is your heart rate (心率)? The data (数据) of your fitness level can help you know what activities you need.

    Design your fitness program

You may have begun your daily exercise. But a personal plan helps more. First, you should have your fitness goals (目标). For example, what do you want to look like, to be slimmer or quicker? A balanced plan will help you start low, progress slowly, do right activities and even allow you to recover (康复) if you get hurt.

    Prepare things needed for sports

You need something practical, enjoyable and easy to use. It could be a pair of trainers, a volleyball or a bicycle. You can also download fitness apps (应用程序) on your mobile phone to measure distances, calories burned or your heart rate.

    Take action

Now you're ready for action. When you begin, don't always try tough tasks. Listen to your body and reduce exercise time if necessary.

   Monitor your progress

Test your fitness level again six weeks later. If you have achieved your goals, increase exercise time to continue improving.

Starting an exercise program is an important decision. By planning carefully and acting step by step, you can have good health.

Think about the colors of fruit and vegetables: the red of tomatoes, the orange of carrots, and the purple of grapes.

You can eat fruit and vegetables of all colors—green, yellow, blue, purple and white. Each color is important to our health. These colors work together for our bodies.

Red gives us a healthy heart. Red helps improve our memory (记忆力). Yellow is good for our eyes. White can reduce (降低) cholesterol. Green is good for our eyes, too. It also gives us strong bones and teeth. Blue helps us keep a good memory as we grow old. It also helps our heart. So when you are buying or eating fruit and vegetables, remember to try fruit and vegetables of different colors.

The chrysanthemum(菊花)is a very popular flower in China. The beautiful flower bas many m{#blank#}1{#/blank#} in Chinese culture. 

The chrysanthemum is k{#blank#}2{#/blank#} as one of the "Four Gentlemen in Plants". The other three are the plum blossom, the orchid, and bamboo. In the past, they stood for noble (高尚的)qualities. 

The chrysanthemum comes out in bright colors during cold a{#blank#}3{#/blank#} days when most flowers die. They are beautiful, strong and tough. The flower thus greatly inspired (启 发)ancient Chinese poets. They spoke highly of its beauty and also used the chrysanthemum to represent(代表)their o{#blank#}4{#/blank#}in their works. 

Tao Yuanming was a f{#blank#}5{#/blank#} poet. He once wrote a poem about living as a hermit(隐士) . He described how he loved the chrysanthemum and used it to show his s{#blank#}6{#/blank#} in the poem. 

"I pluck chrysanthemums under the eastern hedge, and gaze afar toward the southern mountains(采菊东篱下, 悠然见南山), "Tao wrote in his poem. Since then, the chrysanthemum has become the s{#blank#}7{#/blank#} of the hermit. But the chrysanthemum is not only found in Chinese poems. It is also p{#blank#}8{#/blank#} of Chinese food. 

The Chongyang Festival falls on the ninth day of the ninth month of the lunar year. On that day, drinking wine made from chrysanthemums is a popular tradition. Chrysanthemum tea is also usually seen on Chinese dinner tables. It tastes great. People believe it is good for one's health, e{#blank#}9{#/blank#} for eyes. 

In a word, the chrysanthemum has i{#blank#}10{#/blank#}people's life deeply and widely. 

With the growth of pet owners as well as the rise of "Its Economy?，pet cafes, a new business model, are becoming increasingly popular across the country.

For Yu Miao, a cat owner in Hangzhou when she chooses a coffee shop, what matters most is whether it is pet-friendly. ‘There are so many coffee shops in Hangzhou. As a cat owner, I sometimes take my cat out, and I would like to choose a coffee shop that allows my cat to be with me in it," she said.

China's first cat-friendly coffee shop opened in Guangzhou in 2011. With the number of animal lovers like Yu growing in recent years, pet-friendly coffee shops are sprouting up like mushrooms after a spring shower. In February this year, there were more than 4,000 pet-friendly coffee shops in China.

With the development of pet ownership market, pet-friendly coffee shops in other cities are also enjoying wide popularity." During weekends, sometimes visitors have to wait in line before being seated. As customers are all here to enjoy themselves with animals, they think the experience is worth the visit.'' said a pet-friendly coffee shop owner in Beijing.

In Shenzhen, Heytea runs a pet-friendly theme store in Xihui city, Luohu District. The theme store meets nearly all the needs of pet lovers and provides them with a fantastic experience. 

Pet-friendly coffee shop can be mainly divided into two types. One keeps cats and dogs in the shop and enables customers to play with them. Customers need to pay for admission fees in addition to the costs of drinks and snacks. Taking Shanghai as an example, admission tickets for time- limited cat cafes are from 40 yuan to 200 yuan per hour.
