I try not to show the passers-by just how scared I really am, but it's not possible. My tears start to flow, and quickly run to my new, cold bedroom.

I am an only child who has never been more than 30 minutes away from my parents, yet here I am, on the other side of the country, moving into my new college dormitory. We all want to take responsibility for our own lives. I just never realized that in order to do so , I would have to leave my family. No longer will I wake up to Mom's Sunday breakfast. I'll have to solve the daily crossword puzzle on my own without

Dad’s help. It feels like everything I have ever loved is being ripped(强夺) away from me.

As I lie crying into my pillow. I hear the door to the dorm suite(套间)open. It must be one of my two roommates. I quickly stop crying—I wouldn't be able to stand the embarrassment if she found out her new roommate was an emotional person! Much to my surprise, I hear her crying as she runs to her room. Out of curiosity, I tiptoe through the common room to her still-open door.

I stand in the doorway for merely a second before she reacts. Abruptly, her sudden shock at my appearance is clearly written on her face.“ Are you okay?” I quietly ask.“I' m sorry,”" she stammers(结巴地说).“ I thought I was alone. I know this must seem very childish to you. I'm just very close to my younger sister and saying goodbye to her just now…”. Her sentence fades to a whisper as she turns her face away from me.

On May 17, Google held its third-annual youth event at the Google I/O developer’s conference in Mountain View, California. I/O stands for “Input/Output.” The event

inspires kids aged 8 to 13 to love technology, to express their creativity, and to create something in a new way, with their own hands.

This year's event attracted 120 kids from around the San Francisco Bay Area. It was the first time that a whole day was dedicated to(用于) the event.“ Kids are the future,” explains Pani Diwanji, Google’s vice president of engineering. It would be great if we could inspire and empower kids to be the makers of tomorrow.

“Make Your Monster” was the theme of the event this year. Four stations around the room featured a different hands-on activity including design, storytelling, coding(编程),and robotics. Each activity was designed to showcase (展示)technology with creativity. At the storytelling station, kids used the Toontastic app to create an animation starring monsters. At the coding station, kids used Scratch Blocks to design and program a custom dance for their monster.

“Scratch is more accessible and motivational,”says Mitchel Resnick, who works at the MIT Media Lab that developed Scratch. At top universities such as Harvard, some professors teaching the Introduction to Computer Science course start by using Scratch before moving on to other more advanced programs. Research shows that fewer students dropped out of the class when that method was used.

This year's keynote speaker was Brent Bushnell, the CEO of Two Bit Circus, an entertainment company headquartered in Los Angeles. “Google and Two Bit Circus both use the cutting-edge aspects of the world to get everybody excited about science, technology, and math ,”Bushnell told TFK.

Sixth grader Elsa Marroquin says that the Google I/O Youth event really sparked(激发) her creativity.“ When I grow up,” she says,“I want to create robots that will help the elderly with their daily tasks.”

28. What can we learn about Google’s annual youth event?

A. it's for teenagers who love computer science.

B. It aims to design strange-looking robots.

C. It requires participants to be creative.

D. It lasts a whole day every year.

29. What can participants do by using the Toontastic app?

A. Read stories.

B. Make cartoons.

C. Learn to dance.

D. Play with robots.

30.To whom does Mitchel Resnick think Scratch can best be recommended?

A. Animation lovers.

B. Computer engineers.

C. Beginners in coding.

D. Professors in storytelling.

31.How does Elsa Marroquin feel about the Google I/O Youth event?

A. Boring.

B. Surprising.

C. Challenging.

D. Encouraging.

D

Lately there has been a push for more“progressive”conferences, where the child is present during the meeting. I think this trend is a mistake; children should not be present at parent-teacher conferences.

Throughout the year teachers and their students build strong relationships, form bonds and learn from one another. Take me for example. I try to build a child’s confidence so he can achieve certain goals and work hard to climb the ladder of success. In return the child looks up to me, as a role model and somebody to be relied upon to help with learning, critical thinking and questions. Under no circumstances do I ever want to break that trust.

During the parent-teacher conference, teachers must be honest with parents and let them know what areas of learning their child needs help with. But how can you expose a child’s weakness when he is present? It destroys self-image and self-worth. Having chidren present for parent-teacher conferences forces the loving educational environment that the children knows and loves into an interrogation(审问)room.

Children must be responsible for their work in order to grow and reach the areas in which they are most challenged. The parents need to assist in areas where children struggle because education is not a job for one person.

But how can a teacher be completely honest with parents about what they need to do with a child present in the room without hurting that child’s self-worth? Believe me, children already know what areas they need to work on. They don’t need it to be said right in front of their parents. We want to inspire children and not prevent their development in any way.

Parents must be advocates for their children. So when a school says it is important to bring a child into a parent-teacher meeting, the parent has a right to stand up and fight for the child.

32.Who is the author?

A. A teacher.

B. A parent.

C. A school child.

D. A policy maker.

33.What does the author mean by saying“education is not a job for one person”in Paragraph 4?

A. Parents should study what their children are taught.

B. Parents should get involved in their children’s studies.

C. Students should have time to do other things except studying.

D. Students should ask for help when having difficulty in studying.

34.In the author’s opinion, progressive conferences cause a conflict

between________.

A. teachers’ responsibilities and their rights

B. students’ shortcomings and their feelings

C. parents’ expectations and students’ inspirations

D. learning environment and academic achievement

35.What’s the purpose of the text?

A. To introduce how to build up students’ trust in teachers.

B. To discuss the relationship between schools and families.

C. To show teachers’ confusion when preparing parent-teacher conferences.

D. To persuade parents not to bring children to parent-teacher conferences.
