2 . Alexa Bjornson was starting to get worried. Her 7-year-old son, Landon, was set to head off on a flight, but that wasn’t all. Landon was flying all_______ to see his father but had been diagnosed with high-functioning autism (自闭症)．

This means that traveling can be pretty _______ for the youngster. Plus, Alexa wouldn’t be by her son’s side to help him through it all.

The mom knew she needed to make sure that Landon was as _______ as possible. She decided the best way to keep him safe was to tell the other person on the plane. How? Alexa wrote a(n) _______ for Landon to hand to someone. The mom_______ Landon’s diagnosis (诊断) and said that he could be_______ and ask the same questions. Alexa also attached $10 to the note to ask if the passenger could _______ Landon to feel relaxed.

Not only did Landon find a _________ on the plane, but a passenger named Ben sent photo proof that he had looked after Landon throughout the _______. That wasn’t all. Ben also admitted that the $10 was unnecessary, and he had ________ to an autism charity in Landon’s name to help someone else that could need the__________.

Alexa started her day ________ about how her autistic son would cope with the flight. Little did she know that Landon would not only meet a________ friend, but she would learn that some people want to make sure the world is a ________ place, too. Mom of the autistic son learns the ________ of strangers. Fortunately, one good deed soon turned into a chain reaction.

3 . Oscar is a homeless young man in Portland. I _______ him years ago online by chance. I wrote to him last spring to see how I could help him. He has an autoimmune disease (自身免疫性疾病) and lost his_______ during COVID-19 and then his home.

It was months before he finally _______. He hoped to have a fan to keep _______ in the hot summer. We sent him one quickly. Later he said he _______ on concrete (水泥) and needed a ground mattress (床垫). The next month we got him that. He later _______ how wet it is in Portland so I found him a pair of waterproof (防水的) pants. He said that summer was like Christmas as he _______ so many things.

I _______ I could do more. My heart breaks for him. I told him how my son Ben was _______ and how he used to use the name Oscar in a game. “I’m sorry for that. But I’m not your ________,” he said. “I know. But I hope wherever he is, if he is homeless too, a ________ person is helping him.”

The other day I got a ________ from Oscar on the phone: “I have found a job and I just wanted to thank you for your generosity.”

________, most people we had helped for years found homes. One of those, John, leads a fulfilled (充实的) life. And I even plan to ________ a story about his excellent performance. I hope Oscar will find a ________ too. We’ll do whatever we can to help him until he does.
