The college entrance examination is just around the corner.

A study published in the journal Current Biology completely has changed {#blank#}2{#/blank#} people used to think. It shows that the habit of sleeping in on weekends doesn't fix the damage done by a lack of sleep during the week. Even {#blank#}3{#/blank#} (bad), it may damage your health.

Lily loved school. However, there was one class Lily worried about more than any other—art. She didn't know why she just wasn't any good at drawing, painting, or cutting.

Ms. Clay, the art teacher, stood at the front of the room. "Class, next Friday our school is going to have an art competition," she announced. Ms. Clay was a great teacher, and Lily liked her a lot. But this announcement made Lily nervous. "Everyone in the school will create a piece of artwork to show in the library. You can use the different types of artwork we have been studying." Ms. Clay was quite excited when she spoke while Lily found herself sinking lower in her chair.

Lily had the whole weekend to work on her project, but she could not think of anything to do. On Monday, Lily felt frightened, so after school Lily asked Ms. Clay if she could write an art paper instead of doing an art project.

"I understand this project scared you, Lily," Ms. Clay said. "Just remember, you can create any kind of art you want." Ms. Clay smiled at her. "Art is a person's way of expressing his or her feelings—it isn't always painting, drawing, or cutting. I know you will think of something very creative, and I can't wait to see it."

When Lily arrived home, she took out a piece of paper and a pencil. She remembered Ms. Clay's words. "Art is a person's way of expressing his or her feelings." Lily wrote the word "terrified" on her paper. She crumpled (揉皱) the paper and threw it to the side of her desk.

Then Lily stared at the crumpled ball. Suddenly an idea struck her.

Paragraph 1：

Why not create something out of crumpled paper?

Paragraph 2：

On Friday, Lily carefully carried her project into the library.

As an only child, Nicole Renae often felt lonely in her youth. But that all changed when she turned ten. For her birthday, Renae's grandmother 1 her with an adorable gray 2 named Chloe.

From the very start, the two were 3 . "She was my best friend," Renae said. Every ounce of love Renae gave, the little dog returned tenfold.

But when Renae was 14, her father 4 a new job that came with a shocking warning: He'd be working at home, and the house needed to 5 noise disturbance.

"Chloe was very noisy," Renae said. "I was just a kid, so I didn't have any 6 in the matter. I didn't want to 7 my dog. I just felt so sick and 8 about it. With no easier option, the family sent Chloe to a humane society.

9 , Renae grew up, got married, and had a child of her own. But her family didn't feel quite complete. Remembering the 10 that having a dog had brought her as a kid, Renae wanted her daughter to 11 the same. She had it in her mind that she would 12 a puppy, but then one day she saw a post on a social media platform about a 13 dog that needed a new home. The dog in the photograph looked a lot like Chloe —she was even named Chloe. In an instant it was 14 : She would adopt this older dog.

When she met Chloe, the dog seemed so familiar. And Chloe appeared to feel the same 15 about Renae. Soon Renae cried with excitement because she felt so lucky to have Chloe again.

When I lived in Boston, I taught English as a second language to adult students from around the world. On the last day, they threw a nice party. I was amazed they had learned enough English {#blank#}1{#/blank#} （arganize） such an event altogether. At the end of the party, they proudly handed me a gift box. After the box {#blank#}2{#/blank#} （open）, I gently lifted a beautiful coat from it. "We went shopping for a new coat!" they all shouted {#blank#}3{#/blank#} wonderfully perfect English.

The famous Spanish painter Pablo Picasso once said, "I am always doing that which I cannot do, in order that I may learn how to do it." It strikes a chord(引起共鸣) with me because that's exactly what I have been doing these years.

One of my earliest memories of doing before learning is baking scones(烤饼) when I was about 10 years old. I wanted to bake them to surprise my mother when she returned home.

Before that, I'd observed how my mother baked them many times. As I started to try, I didn't know I shouldn't handle the dough(面团) with my hands too much once I'd added the baking powder(发酵粉). However, I knew exactly how to roll out the dough and use a cookie cutter to cut the scones, because my mom had already taught me.

By the time my mom arrived home, the smell of freshly baked scones welcomed her into the kitchen. They were close to perfection—flat, as a result of overhandling the dough, but they tasted OK. My mom sweetly praised me for my attempt, rather than scolding me for the state of the kitchen, which was like a tornado had just blown!

Have my attempts always been successful? I wish! Some of my kitchen disasters were so terrible that even the dogs wanted nothing to do with them. My gardening failures didn't live to see another season.

But my habit of doing before learning is still helpful. Whatever new software I have to learn how to use, I do so by simply starting to use it. I do, learn, and improve. So if you ask me whether I regret that I tend to do first and learn later, I'd say I don't, because what I have discovered from those is the wisdom to know when it's OK to do and then learn, and when it's probably better to learn and then do!

Cruz Genet,11, and Anthony Skopick, 10, couldn't agree. Were the birds out on the ice ducks or geese? So on a 1 January evening last year, the two friends ventured onto the 2 pond near their homes, to get a better look. First they tossed a rock onto the ice to3 it. Then they stepped on it. 4 the ice would hold their weight, Anthony took a few steps, then…FOOMP. He crashed through the 5 frozen surface." There was no sound, no crack," he recalled,"I just fell through instantly". Cruz 6 to help his panicked friend. FOOMP— the pond 7 him too.

 The boys were up to their necks in icy water and quickly losing feeling in their limbs. Any chance of their 8 themselves was slipping away. Cruz was sure he was going to die. Anthony's older sister was nearby and started screaming for help.

 John Lavin, a9 driving nearby on his way home, heard her. He quickly 10 . Seeing the boys, he grabbed a nearby buoy (救生圈), 11 off his shoes, and ran into the cold water, chopping(劈) his way through the ice with his free 12 .

 Lavin made his way to Cruz and Anthony and pulled them back to land. When in hospital, doctors discovered that their five- minute 13 in the water had lowered their body 14 nearly ten degrees.

 Fortunately, the boys have fully recovered, though they are still a little awestruck by their 15 neighbor." Just to think," says Cruz," If he weren't there, we could have died."
