Clothes are traditionally made of natural materials, such as cotton, leather and wool. They are all from plants or animals, but that doesn't mean they're friendly to the earth. For example, farmers have to use a lot of chemicals to grow cotton plants.

    Scientists are now looking for new ways to make clothing materials. They hope the new materials are both comfortable and good for the earth. Scientists have worked out how to make materials out of cornhusks (谷壳), chicken feathers and rice straws.

    "They used to be useless things. We always have a problem of how to deal with them," Yang, a scientist says. "Now, we can turn them into beautiful materials. Chicken feathers are better than other things. They have small air pockets like honeycombs. That means it will be very warm if you use them to make a jacket or sweater, and I think more and more people will like to buy these kinds of clothes."

    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.

Look at the picture! You can {#blank#}1{#/blank#} some school things(学习用品) in it, some {#blank#}2{#/blank#} and pencils, two erasers and two dictionaries. The blue eraser is {#blank#}3{#/blank#}. Itˈs big. The green eraser is Lucyˈs. She is my good {#blank#}4{#/blank#}. We are in the same(相同的) school. This is my English dictionary. What {#blank#}5{#/blank#} the Chinese {#blank#}6{#/blank#}? Oh, itˈs Lucyˈs. My English {#blank#}7{#/blank#} is Mr. Brown. {#blank#}8{#/blank#} first name is Bill. He is a good teacher. We thank him(他) {#blank#}9{#/blank#} his {#blank#}10{#/blank#}.

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.

① A survey(调查) has shown that lots of people can't sleep well. Sometimes you feel tired when you wake up. You may have a headache and you feel like you could sleep for another three hours. Many things around us cause sleeplessness. Here are a few changes you can make to improve your sleep.

②Go to bed and get up at the same time. You may share the same bedroom with your sister or brother. You both must go to bed regularly(规律地) so that you don't trouble each other.

③Clean up your bedroom. A study from a university in Zhengzhou found that people with clean bedrooms usually sleep better than those with dirty and untidy rooms.

④ Get more house plants. Studies show that house plants help with reducing (减轻)stress. Also, plants such as lavender(薰衣草) and gardenias(栀子花) have smells that may help some people relax and sleep better.

⑤ Make your room dark. When light hits your eyes, it tell you not to fall asleep. In fact, we need darkness especially in the evening. So if you want your body to know that it's time to rest, turn off the lights about an hour before bedtime or wear eye masks. Your phone and your TV should also be thought of. You may also use the dark curtaıns(窗帘) to keep any outside light from going into your bedroom.

⑥Lower your bedroom temperature. The body becomes cooler at night, so lowering the temperature before bedtime can help you relax and fall asleep more quickly. The NationalSleep Foundation in a country says your bedroom should be about 16 ℃ to 19℃ for a good night's sleep.
