Jenna, a popular girl from Westwood Middle School, had graduated first in her class and was ready for new1 in high school.

However, high school was different. In the first week, Jenna went to tryouts{#blank#}1{#/blank#}(选拔赛) for cheerleaders{#blank#}2{#/blank#}(啦啦队队员). She was competing against very talented girls, and she knew it would be2 for her to be selected. Two hours later, the3 read a list of the girls for a second tryout. Her heart was down as the list ended without her name. Feeling4 , she walked home carrying her schoolbag full of homework.

Arriving home, she started with maths. She had always been a5 maths student, but now she was struggling. She moved on to English and history, and was happy to find that she didn't have any trouble with those subjects. Feeling better, she decided not to6 maths for the time being.

The next day Jenna went to see Mrs Biden about being on the school7 . Mrs Biden wasn't as8 as Jenna. "I'm sorry, but we have enough9 for the newspaper already. Come back next year and we'll talk then." Jenna smiled10 and left. "Why is high school so11 ?" she sighed.

Later in maths class, Jenna devoted herself to figuring out the problems that had given her so much12 . By the end of class, she understood how to get them right. As she gathered her books, Jenna decided she'd continue to try to fit in at her new school. She wasn't sure if she'd13 , but she knew she had to try. High school was just as her mum had said, "You will feel like a small fish in a big pond14 a big fish in a small pond. The challenge is to become the15 fish you can be."

It was the end of the school day, and I was tired. I grabbed a pile of about 130 exam papers to1 on the train ride home. I'd bring them back the next morning.

My principal (校长) pushed her head into my classroom and said, "Friendly2 ! You need to make sure your word wall is3 by tomorrow morning." She then moved on to the next classroom to4 the message. I sighed and thought, "Are you making a(n)5 ? What a waste of my time!"

My principal was6 about making our school beautiful, while my goal was to get my students to pass the Algebra Regents Exam. She wanted every classroom to have a word wall, where student's works on creative projects would be7 . She brought in beautiful planters (花盆) that8 the hallways with greenery. However, I assume that school and classroom9 aren't important when it comes to learning. To me, spending time and money making our school and classrooms beautiful was just a distraction (使人分心的事). Those things don't10 my students with math.

However, after three years of teaching, I went to graduate school in part to study how resources 11 teachers and students. What my research found 12 me: When teachers 13 their classroom environment resources, their students did better on standardized tests. My principal was 14 . She was creating more than just a beautiful 15 —she was building a welcoming and positive environment for students to learn and teachers to work.

When I first heard about the improv(即兴表演) classes, I was torn. As an introvert, I feared getting on stage and improvising in front of strangers. However, I knew I wanted to work as a science communicator after finishing my Ph.D. , so it seemed like the perfect opportunity to improve my speaking ability and gain confidence thinking on my feet.

During our first class, we learned a core concept of improv: "yes, and." It means that, as improvisers, we accept what fellow performers say. If someone says that rhinos(犀牛) are librarians, for example, then rhinos are librarians. We do not question the logic; we say "yes" and continue with the scene as if no him is wrong.

I got a taste of how difficult that was when acting out my first scene. My classmate turned to me and said, "Mom is going to be so mad." Mad about what? My mind spun out ideas, and my inner critic shot them all down. We broke the car? No, that's too easy. We failed a test? No, you don't want your classmates thinking you're stupid on the first day. I finally landed on an answer: "Yes, we're going to be late for dinner." The scene proceeded from there, and we eventually finished as two sisters who lost their way on a hiking trail.

The first few scenes were hard, but as weeks turned into months, I became more comfortable thinking on my feet and even started to enjoy our classes. I never silenced my inner critic entirely, but over time, I didn't police my words with quite so much effort. I also became better at listening, relating to my conversation partners, and communicating clearly in the moment.

That training proved useful 6 months ago, when my experiments generated unreasonable data. Early on in graduate school, I would get stuck when this happened; my inner critic would assume I had made a mistake. But then, after embracing the "yes, and" concept, instead of getting discouraged, I kept exploring the data and ended up identifying a new type of cell—one that wasn't behaving as expected. If I hadn't accepted the possibility that the results were real, I would have missed out on the most exciting finding of my Ph.D. so far.

All scientists can benefit from this lesson. If the data say rhinos are librarians, then it's worth investigating whether rhinos are, in fact, librarians. Our job as scientists isn't to generate data that support a preconceived(预想的) story. Our job is to say "yes, and."

They talk about the straw that broke the camel's back, but really it should be the password that wiped out my memory bank. 

I was going along fine -with instant recall of my bank PIN (密码)，my mobile phone number and the date of my cousin's birthday before I downloaded a gas station payment app for its new customer discount. It asked me to create a password. When I typed in "gas 1", it was rejected for not being complex enough. I tried again: "IHateHearlessOilCompanies@". But that was too long and didn't include "at least one number". But here is the thing: as soon as 1 added the fresh password into my memory, I instantly forgot all the others. My brain had hit its limit for passwords. I now know nothing. 

I had entered some passwords in a notebook. Of course, I didn't write down the actual passwords, in case it fell into the wrong hands. Instead, I masked them in a way that only a family member could figure them out. For example, I combined my bank PIN with our postal code, then added it to a list of phone numbers. It would fool even Albert Einstein.

Maybe we need a system like the one we use to remember people's names. You know, you form an association between a person's characteristics and their name by whispering "Skinny George, Skinny George" in heart after meeting them. The risk is that, upon seeing him, you'll burst out the phrase. "Skinny George" might not mind, but it's possible "Boring Betty" will. As for remembering passwords as you change them, you could simply use the first and last letters of your favorite singer's greatest hits, together with the year of their release.

Maybe I'll try that one out- -but only after describing the system in the notebook. Then I'll hide it in a place so secret that I'll never remember where it is. 

"I'm going to play basketball, Daddy." Lauren flew into my arms when I came in from work. "That's 1 , honey," I replied naturally. I thought she meant outside the house—on the driveway. Into the kitchen, my wife Helen's silence indicated I had 2 something. After a while, she spoke slowly, "Lauren is joining the girls' high-school basketball team."

I 3 my girl's sportsmanlike courage, but 4 was still in my stomach. Lauren was only just 1.55m tall. 5 legs and a heavy body were surely a(n) 6 for her in playing basketball.

Finally, the game day arrived. Lauren and her teammates moved out. Their game faces seemed 7 to win. At first, though not playing, Lauren followed the movement on the court and 8 every play. I could even 9 her shout "No way!" when a referee made an unfair call against a teammate. Sitting on the sidelines, Lauren still enjoyed the game very much.

Suddenly, the announcer's voice boomed, "Number thirty-three, Lauren Wray, in." My heart 10 wildly. What if she got injured or other girls on the team made fun of her? But what I saw was that Lauren made every effort to keep pace with the others. Just before the end of the game, they 11 the ball to Lauren. She caught it. She shot. 12 she scored!

The audience began clapping and 13 . Lauren's brown eyes shone as she wiped her sweaty forehead. Lauren's uplifting spirits and impressive performance, wrapped in a small 14 , struck everyone greatly. I felt enormously 15 to have Lauren as my daughter.

Let's do something in our daily life for the environment and the earth.

An English teacher has introduced a play to her class.

Characters: Benny, Jerry, Susie, Grace

Time: One Sunday afternoon.

Place: By the river near their houses.

（The four teenagers have just finished the picnic. They are tidying up.）

Benny: Wow! That was a great picnic. I'm so full that I can hardly move.

Grace: That's no excuse for not tidying up, Benny. Come over here and help me pack（包装）up the leftover food. Jerry, please? And clean up the place.

Jerry: （Speaking unhappily to himself.）How can I always get the dirty and difficult jobs? It's not fair.

（Jerry throws a bit of water on the fire. Then he picks up the ashes（灰烬）with an old newspaper and wants to throw them into the long grass.）

Susie: （Sounding surprised）What are you doing, Jerry? That's d....

Jerry: Whoop...the paper has caught fire.

Susie: And the grass…Benny, Grace, help! Help!

（Benny and Grace come over quickly. They help put out the fire completely.）

Jerry: Oh, no. Oh, no! What have I done? 

Grace: You know that we should do everything carefully, don't you? 

Jerry: （With his head in his hands.）Yes. What have I done? What have I done?
