When an ice cream sundae(圣代冰淇淋) cost much less, a boy entered a coffee shop and sat at a table. A waitress put a glass of water in front of him.

    "How much is an ice cream sundae?"

    "Fifty cents," said the waitress.

    The little boy pulled his hand out of his pocket and studied a number of coins in it. "How much is a dish of plain ice cream?" he asked.

    Some people were waiting for a table, and the waitress was not patient. "Thirty-five cents," she said angrily.

    The little boy again counted the coins. "I will have the plain ice cream," he said. The waitress brought the ice cream and walked away. The boy finished, paid the money, and left.

    When the waitress came back, she was surprised at what she saw. There were fifteen cents placed beside the empty dish. That was her tip.

    Boyan Slat has one huge goal. It's a goal that could be good for people and a {#blank#}1{#/blank#} all over the world. Amazingly, it looks like he's going to m {#blank#}2{#/blank#}his goal.

    When he was 16  Dutch engineering student Slat was on vacation in Greece, and he started to think about all the rubbish that is p{#blank#}3{#/blank#} onto beaches by water. The oceans around the world are all of plastic—millions of tons of plastic. Unfortunately, plastic doesn't just disappear. It takes c{#blank#}4{#/blank#} to break down (分解).

    The p{#blank#}5{#/blank#} situation of the oceans is bad and worrying and Slat wanted to do something to change it. So he made it a personal goal to clean up the rubbish in the world's oceans.

    Slat started with an idea for an unusual m{#blank#}6{#/blank#} to "catch" the plastic floating (漂浮) in the water using the natural energy of the ocean. He left school in 2013 to begin work on his project The Ocean Cleanup. Soon, the project r{#blank#}7{#/blank#} a lot of attention.

    A year later, he was leading a team of 100 scientists and engineers working on the invention. Slat needed money for this, so he started asking people to d{#blank#}8{#/blank#} to his project online and raised over $ 2 million!

    Soon after, Slat was named a "Champion of the Earth" by the United Nations for his meaningful and v{#blank#}9{#/blank#} work. It's the most important title the UN gives to people helping the environment. The Ocean Cleanup also won several awards (奖项) for having one of the best inventions of 2015. But the d{#blank#}10{#/blank#} goes on for Slat. He hopes that the oceans will be free of plastic in about twenty or thirty years.

Teresa is a 25-year-old girl who works at a bank. She sometimes  {#blank#}1{#/blank#} （想念） her happy time at school. 

My First Day 

I'll never forget my first day at primary school. I got to school early but I still felt really  {#blank#}2{#/blank#} （紧张的）. Luckily，a girl was kind enough to  {#blank#}3{#/blank#} （邀请） me to sit next to her. We were all together and the head teacher with thick  {#blank#}4{#/blank#} （眼镜） welcomed us. He looked so kind that {#blank#}5{#/blank#} （没有一人） of us felt afraid of him. 

My First Teacher 

I remember her name is Mrs Simpson. Her voice sounded really sweet. Moreover，she was more  {#blank#}6{#/blank#} （幽默的） than any other teacher in our school.  {#blank#}7{#/blank#} （也许） she was my dream teacher at that time. 

Sports Day 

Sports Day was the best day of the year!I used. to take exercise with my friends after school. My {#blank#}8{#/blank#} （业余爱好） is running，so I took an  {#blank#}9{#/blank#} （积极的） part in the running race and I won he third prize!But I haven't won a better prize {#blank#}10{#/blank#} （还、尚）. 

I am Mandy and I live in the city with my parents and my little sister. The city life is boring sometimes. I love going to my grandmother's village(村庄). 

It is so much fun living in the village. I like collecting leaves (收集树叶) there. I usually do it on my way to the only shop in the village. They have many different shapes. Some are like a heart and some are like a hand. . . I can make a lot of things with leaves. One fun thing is making leaf pictures. 

This is how I make a leaf picture. I take a leaf out and I also need paper, glue (胶水), a brush(刷子) and paints (绘画颜料). First, I glue the leaf onto the paper and wait for an hour. Then, I paint over the leaf and the paper and let the paints get dry(变干). Next, I take the leaf off the paper. There it is—a beautiful leaf picture on the paper!

I sometimes make birthday cards or other things with the leaf pictures. My friends like them very much. I tell them，"They are not just gifts from me. They're gifts from my grandmother's village！"

I had a trip to Aruba on my vacation. We 1 the Holiday Hotel in Aruba at about 1:30 a. m. We were pretty glad 2 it was our first trip to Aruba. The flight （飞行） was fine and the bus ride from the 3 was great. We stayed at the Holiday Hotel. We saw the rooms one 4 one because we wanted to have a room to 5 the sea（海洋）. 

I would say that the beach was 6 but the weather was awful every day. 7 the Holiday Hotel, it was okay with us. The room was clean. The waiters were friendly and the food was good. I 8 the food of the hotel restaurant. One night we had 9 at the Moomba Restaurant. It is on the third floor. The food there was really good. The Moomba was a good place to 10 . I hoped to go there again.
