When I was growing up, I do not recall     1     (hear) the words “I love you” from my father. When your father never says     2     to you when you are a child, it gets more difficult for him     3     (say) those words as he gets older. To tell the     4    (true), I could not remember     5     I had last said those words to him either. I decided to change it and make the first move. After some hesitation (犹豫), in our next phone conversation I spoke out the words, “Dad … I love you!”

There was a silence at the     6     end and then he     7     (embarrass) replied, “Well, same back at you!”

I laughed and said, “Dad, I know you love me, and when you are ready, I know you     8     (say) what you want to say.”

A few weeks later, Dad ended our phone conversation     9     the words, “Paul, I love you.” I was at work during this conversation and the tears were falling down my face because I finally “heard” the love. As we both sat there in tears, we r    10     that this special moment had taken our father-son relationship to a new level.

Have you ever paid attention to your school’s security guards? Would you say “good morning” to the cleaners? For Ding Jiacheng, a boy from Hangzhou Entel Foreign Language School,     1     is a problem that many students ignore the important jobs done by these non-teaching staff. He wanted to make     2     change.

Ding worked on a project called “The Invisible Are Significant”,     3     (hope) more students would respect the “invisible” staff. The project won a prize at China Thinks Big, a competition     4     (hold) by Harvard and Tsinghua University to encourage teenagers to explore important     5     (globe) issues and focus on solutions.

To investigate students’ attitude     6     this group, he designed a questionnaire. “In one question, 56 percent of the students said they would greet those non-teaching workers,     7     only 17 percent strongly believe that every student should do so,” said Ding.

The main reason, according to Ding, is that students know little about the work done by them and have few     8     (chance) to communicate with them. Therefore, Ding’s team     9     (shoot) videos to show staff working on campus. They also held a basketball match between students and non-teaching staff to increase their interaction.

“Explore and understand society in practice, and influence the people around us. That’s     10     the meaning of the project lies,” said Ding.
