My wife and I sat together，alone there for the first time.I began to feel sad，a longing for something I couldn’t describe well.I glanced at my wife.A tear rolled down her cheek.She was feeling the same thing.I slid over，and we held hands.Our last child was entering the first grade，and we felt part of him slipping away.He’d be in school for a full day now.He’d be more independent，and need us less often.And，he’d never again be the toddler he once was. In our “stay positive” culture，many parents only see these times as a reason to celebrate.They see it as an inevitable change，and prepare themselves for the next challenge.But I couldn’t help feeling this.I didn’t want to bury my feeling of sadness.Those who protect themselves from these moments lose a great opportunity of growth.It is the kind of growth that results from pain，and makes us all more a part of the human family. Half an hour later，my son returned to us，his eyes twinkling.He was excited to tell us about his new experience.We listened to him，and his smiling face helped to ease the sadness.In fact，it was impossible not to feel happy for him. Loving_your_kids_is_not_always_easy.There are painful times when we see them moving away from us.But we must not avoid or run away from these feelings，for they give us the chance to increase our capacity for joy，while we are experiencing great sadness. 16．The author’s son stayed with his sister close maybe because ________. A．he had to walk with the help of his sister B．he wanted to be protected by his sister C．he was not only scared but also very excited D．he didn’t want to leave his parents alone 17．When the author’s wife saw their son leave，she was ________. A．heartbroken B．warmhearted C．disappointed D．hopeful 18．We can know from the third paragraph that________. A．it is wrong for parents to protect their children B．many parents are very cruel to their children C．it is very dangerous to meet the challenge D．children can grow by joining the human family 19．The underlined sentence “Loving your kids is not always easy.”(in Paragraph 5) is most likely to tell us that________. A．it is difficult for you to love your kids B．you’d better not love your kids any longer C．loving your kids sometimes makes you painful D．you’re really happy to love your kids sincerely 20．The author has written this passage in order to tell us that________. A．we shouldn’t allow our children to go to school early B．sadness is a normal feeling when our children leave us C．we should let our children live independently D．happiness is actually as important as sadness B Sitting across from a German couple and a Chinese mother and her child，we were waiting at the Guilin airport for our delayed flight to Shanghai.In this last week of our travelstudy tour，my husband and I were savoring this short break by reading. I tuned out the languages I couldn’t understand.But it was an American accent that pulled my attention from my book.It also pulled the attention of three rows of people seated around us as the American barked，“Coming through！Coming through！” At the same time，an oversized man pulling an oversized carryon passed our row.His wheeled bag caught the German’s feet.Turning to see what snagged his luggage，the American fellow yanked his bag so hard that it crossed over the man’s feet.It was then that my horror struck.There was no “I’m sorry”，no “Excuse me” and no “Pardon me” coming from this countryman of mine. While this wasn’t the first or last incident where I sighted discourteous，illmannered，rude Americans in China，each produced similar feelings.First，I was embarrassed that someone from my country was creating a negative impression of Americans.My second reaction was a desire to apologize.I wanted them to explain to the Chinese woman and her child，the German couple next to them，and everyone nearby that this was not typical American behavior.I wanted them to know “we” were all not like that. I never got to explain，or to apologize.Language differences made that option impossible，and rational thinking made it inappropriate.And it turned out not to be a need.The German caught my eyes with a bit of headshaking，smiling and eye rolling，which I returned，and it was clear that he knew we were Americans and was expressing that there was “no need” to apologize for “universal idiot behavior”． 21．In the airport the author and her husband ________. A．were talking with a German couple B．were having a good time C．were enjoying reading together D．were worrying about their flight 22．According to the author the man with an American accent was________.
