Did you hear the song called Heartbeat? It's very {#blank#}1{#/blank#} in the world. Zade Dirani released (发布) this song {#blank#}2{#/blank#} March 15^th 2018 to remember the seven years of war (战争) in Syria. In the song, one of the {#blank#}3{#/blank#} is Ansam. She is a ten-year-old girl. When she was born (出生), she couldn't see {#blank#}4{#/blank#}. But later people found she could sing very well. She sang the song Heartbeat with another 40 children. They all lost their parents in the war. In this song, children hope (希望) they can have a happy {#blank#}5{#/blank#} and there is no war in Syria. But many people lost their homes {#blank#}6{#/blank#} the war broke out (爆发) on April 13^th 2018 again. Everybody hopes the war can {#blank#}7{#/blank#}. We hope all the kids have food to eat. They can live with their parents. They can study in the classroom. They can sing under the trees and swim in the sea.

    We are lucky to live in a great {#blank#}8{#/blank#}, China. Now we have food to eat. We are {#blank#}9{#/blank#} in the classroom. We {#blank#}10{#/blank#} reading books in the library. So we should study hard and love our parents and friends.

    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!

Hong Kong is surrounded(环绕着的) by mountains and seas. It lies in southern China, and is China's"South Gate"to the world. In the old days, HongKong was only a small fishing village, but now Hong Kong has become an important trading center and shipping center in Asia and the Pacific. Since HongKong's return to China in 1997, the rule of law system has been perfected.

Hong Kong is made up of three large parts and nearby islands. There are few flat areas in Hong Kong, and only a small part of the coastal area is low,surrounded by hills. Because Hong Kong is one of the most densely(稠密地) populated areas in the world, dozens of high-rise buildings are built on hillsides.

Hong Kong's tourism industry is highly developed. There are all kinds of goods from all over the world, and the prices are very low, so Hong Kong is a good place for buyers. It is also a place where Chinese and Western cultures mix. Food from all over the world is brought together to make Hong Kong a"FoodCapital". Every year,a large number of tourists from all over the world come to visit.

Imagine walking around a fashion store. You see a beautiful leather bag and want {#blank#}1{#/blank#} it. But in fact, it's made from recycled fruit and food waste. Would you still buy it?

Song Youyang, a 30-year-old material designer, works on developing products. She studied material design at a university in Germany and now lives in China. {#blank#}2{#/blank#} she was designing some new products, she couldn't find any suitable biomaterials (生物材料) to work with. So, she and her team decided to develop {#blank#}3{#/blank#} own new material from fruit waste.

The resulting material {#blank#}4{#/blank#} a lot like leather. It keeps the fruits' texture (质地), sense of touch and nice smell. Song and her team have used this new material to make fashion {#blank#}5{#/blank#}, such as bags, lamps and so on.

The designer thought these products would be {#blank#}6{#/blank#}. But in fact, not many customers have bought them. "Many people have their old ideas about biomaterials," said Song. "They think these materials are too expensive or of {#blank#}7{#/blank#} quality." As a result, it's quite difficult for these materials to become {#blank#}8{#/blank#} used. But Song still believes biomaterials will shape the {#blank#}9{#/blank#}. She and her team will {#blank#}10{#/blank#} working on new types of "green" materials and products.

Besides Song's team, many other fashion companies are {#blank#}11{#/blank#} working towards the same goal. They are showing us that fashion can be environmentally friendly.

Summer is almost here. It's a great time to go out and play. But take care. The weather gets hot, too much sun is unhealthy. How can you stay healthy this summer?Follow these tips.

Drink water.Hot weather makes you sweat(出汗). Your body needs more water to keep you cool and stay healthy. Drink lots of it, even when you are not thirsty.

Pick the right clothes. Make sure they are white color or light color and a little big.

Wear sunscreen. The sun's rays are stronger than you think.Sunscreen can stop some of those rays. Look for SPF30 or higher.

Listen to lifeguards. Lifeguards work at beaches and pools.They help us stay safe in the water.

The Americans believe that anybody can become President of the United States. In a recent Hollywood comedy (喜剧), that is exactly what happens. 

Dave Kovic, played by Kevin Kline, is a kind-hearted man who runs a business that finds people jobs. He leads a typical (典型的) American way of life, except for one thing — he looks exactly like the President, Bill Mitchell. In fact, the only thing that makes him different from the nation's leader is that he is very nice! 

The president has started using look-alikes during some public appearances. Dave is offered a chance to "serve his country" by becoming one. However, things go wrong. The President becomes very ill and Dave ends up acting as the President forever. 

Director (导演) Ivan Reitman, who made the popular and successful comedies like Twins, Ghostbusters and Legal Eagles, could have gone for easy laughs by making fun of the American government. Instead, Dave is an attractive comedy about an ordinary man in extraordinary (非凡的) situations. Kevin Kline gives a double performance as Dave and the President, and Sigourney Weaver is at her best as his First Lady. The love story that develops between her role and Dave is a real classic (经典).

The film is 100% American. However, if you've ever felt that anybody could do a better job running the country than the people in power, then you'll enjoy Dave!
