1 . Age has never been a problem for Thessalonika Arzu-Embry. After all, she’s already got her master’s degree.
The North Chicago-area girl started homeschooling at the age of 4. She began having an influence on others soon after. When she was 6 years old, she was an inspirational speaker at an organization called Tabitha House Community Service, a shelter for people who were forced to leave their homes due to the situations such as earthquakes, flood and other natural disasters.
At the age of 11, she graduated from high school and then earned her bachelor’s degree in psychology in 2013. She completed those classes online as she was traveling for leadership meetings.
She doesn’t stop there, though. The girl plans to take up aviation psychology (航空心理学) for her further study, a decision inspired by her father who is a pilot. She grew up around airplanes and took flights all the time. Her goal is to use it to determine whether pilots are dealing with problems that could have deadly results once the plane takes off — a topic that has been in the news lately. For her, it’s a mix of two of her interests.
In her free time, Thessalonika enjoys playing tennis, swimming and being active in her youth group. She also has three self-published books, which are on her site. Jump the Education Barrier is written to help students finish college, and In the Future aims to help business owners deal with trends. Her third book The Genius Race has a wider appeal. It is designed to help people to be geniuses in various areas of life.

4 . AP at a Glance
Get an Overview of the AP ProgramThe Advanced Placement ® Program (AP) enables willing and academically-prepared students to pursue college-level studies while they are still in high school. The program develops college-level courses that high schools can choose to offer and corresponding AP exams that are administered once a year.
Fast Facts·AP courses are available in seven subject categories.
·Each AP course is modeled on a comparable introductory college course in the subject.
·Each course comes to an end in a standardized college-level assessment or an AP exam.
·AP exams are given in May each year at testing locations all over the world.
·Schools must be authorized by the AP Course Audit to offer approved AP courses and use the “AP” designation (名称).
AdvantagesTaking AP courses and exams can help students:
·Stand out on college applications. AP courses on a student’s transcript (学生成绩报告单) show that they’ve challenged themselves with the strictest courses available to them. And success on an AP exam shows that they’re ready for college-level coursework.

5 . I was typing papers for new school students when Mama called. We talked about some senseless things for a while before she finally told me about it. “Well, Donner, there’s this class up at the high school this summer.” She said. “They say they can teach me to read and write. I’m trying to decide whether.”
“Of course, you should do it! That would be so wonderful. I’d be so proud of you.” I answered. She was 63 and had survived two alcoholic husbands and was an expert at buying and selling garage sale junk to keep food on her own table and buy Christmas presents for me and my brother’s kids. She used food stamps to buy food and other goods. Mama laughed, seemingly with relief. “Well, you know, I’d about gotten used to being the silliest old lady in town,” she said.
It turned out that her neighbor had found the class for her. The young woman had been doing Mama’s “business” for a while in my absence, helping to relieve my guilt over leaving Mississippi. The friend was a little crazy, but Mama liked her. She was real and, by then, I hated pretension as much as Mama did. When I was little, she would tell me: “Remember, Donner Kay, nobody’s better than anybody else.”
Three months into the class. Mama left a message on my answering machine: “Donner, I taught a class tonight!” She was almost singing the words. “The teacher let me teach the class!” She soon wrote me a letter in a careful, boxy print I had never seen, instead of the strange way she had long written family names she had memorized.
The next time I flew home to visit, we both laughed like 12-year-olds as she read words from billboards on the way from the airport. Her grammar was getting better. She kept talking about her classes and the other students.

7 . The campaign to reduce food waste is in its third week, and we’re already seeing some great results. We’d like every student and teacher to join in the campaign, so if you haven’t started yet, read our blog and join in!
Stop wasting food at school.
“The children are making a big effort to think in a sensible way about the food they put on their plates. We now have about 15% less waste and we think this percentage grows as more children join in the campaign,” school lunch director Marge Kaplan said. The school canteen now offers two portion (份) sizes for all main meals: small and large. This week they’ll replace single bread rolls with slices of bread. You can take as many slices as you want, but one at a time.
Latest news!
From next week you’ll be able to put any waste from fresh fruit and vegetables into the special green bin at the back of the canteen. Miss Norris, the school gardener, will empty the bin each day into a giant compost (堆肥) container in the school’s vegetable garden. That can be used to improve the quality of soils.
Stop wasting food at home.
Every year, we waste about a third of our food. In the UK, more than 97% of food waste ends up in a landfill (废物填埋) site. That’s a lot! Come to a special meeting with supermarket owner Carlos Rodriguez to learn how we can save food and money at home!
Campaign meeting!
When: Friday 12 May, 5-6 p. m.
Where: School hall
What: Top tips on how to store food, measure sensible portion sizes and cook tasty meals from leftovers

8 . Safety problems greatly affect many parts of the world. In China, safety education is becoming more and more important now. The day of safety education for primary and middle school students falls on Monday in the last week of March each year. It helps students learn more about what they should do to keep themselves safe. What are the accidents at school? Let’s take a look.
A stampede always happens in crowded places. When students around you begin to push, just stand there and try to hold onto something. If you fall down in the crowd, move to one side and protect your head with your hands around.
When earthquakes happen, you can get under a desk quickly and hold on. It’ll protect you from falling things. If you are outdoors, find a place away from buildings, trees, and power lines.
When there’s a fire, leave the classroom quickly. It’s better to put something wet over your mouth and nose. In this way, you won’t breathe in smoke. Many people die in a fire, not because of the fire but smoke. It makes them cough and they can’t breathe. That’s very dangerous! So when you want to get out, you should make yourself close to the floor. Then you can breathe some fresh air. Remember, the most important thing is to stay calm in a fire.
Stampedes, earthquakes and fires are the main accidents at school. If you can remember safety knowledge and survival (生存) skills, you will live a safe and happy life.

※At Ross. we provide students with a focused and supportive environment for mathematical exploration. We encourage mathematical cooperation and community building, instead of direct competition between students.
※At Ross, we want to create an environment that allows students to explore their relationships with mathematics, and we try to create an experience that allows students to explore mathematics deeply, to experience mathematics for themselves, and to share this exploration and joy with others.
Ross Staff
We have excellent counselors (辅导员) who are responsible for teaching mathematics, providing social and emotional support for students, and monitoring student safety. They are also responsible for being role models for students, and for developing a welcoming camp culture among the participants.
Program Dates
There will be two sites for the Ross Program:
※At Otterbein University in Columbus, OH. June 9 through July 19, 2024
※At Rose-Hulman Institute of Technology in Terre Haute, Indiana, June 16 through July 26, 2024
All participants typically live with a roommate in a campus dormitory.
Applying
※Pre-college students who are interested in mathematics are invited to apply. First-year students range in age from 15 to 18 years old, but in unique cases, younger or older students are accepted. We expect about 60 first-year students at each site.
Admission decisions are based on school performance, teacher recommendations, essays about the applicant’s interests and goals, and the applicant’s work on some challenging math problems.
The fee for attending the program is $7,000, though we’re able to provide financial aid for students who need financial assistance to attend the program. The student fee covers tuition, housing and meals.

10 . When high school students spend time memorizing and reciting a poem, they develop confidence by engaging deeply with language. Here are my five Cs — things I’ve observed from several years of teaching students through Poetry Out Loud, from selecting a poem to performing at the state competition.
Concrete learning task. Learning just one poem well gives students a finite and concentrated experience with language. And every student can learn one poem. I’ve seen students with all manner of challenges get up and do something they thought was impossible,
Continuing learning. Students learn a poem that will likely stay with them for years, if not forever. Poems contain mysteries and complexities that reveal themselves slowly — and sometimes even suddenly — over time.
Confidence.
Challenging memory and recall. Students are not asked to memorize much anymore, yet many of them take pleasure in the act of repetition and remembering.
| A．Chance. |
| B．Choice. |
| C．so you can rely on it that you can recite poems. |
| D．Therefore, it is a lasting course to learn poems. |
| E．in large part because it involves a single, repeated exercise. |
| F．Recitation is the perfect introduction to public speaking skills. |
| G．They like testing themselves and realizing that they can in fact recall lines. |
