classroom.His face showed a mix of fear and excitement，and he stayed close to his sister as he moved down the aisle.My wife and I sat together，alone there for the first time.I began to feel sad，a longing for something I couldnt 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.Hed be in school for a full day now.Hed be more independent，and need us less often.And，hed 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 couldnt help feeling this.I didnt 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.16The authors son stayed with his sister close maybe because _.Ahe had to walk with the help of his sisterBhe wanted to be protected by his sisterChe was not only scared but also very excitedDhe didnt want to leave his parents alone17When the authors wife saw their son leave，she was _.AheartbrokenBwarmheartedCdisappointedDhopeful18We can know from the third paragraph that_.Ait is wrong for parents to protect their childrenBmany parents are very cruel to their childrenCit is very dangerous to meet the challengeDchildren can grow by joining the human family19The underlined sentence “Loving your kids is not always easy.”(in Paragraph 5) is most likely to tell us that_.Ait is difficult for you to love your kidsByoud better not love your kids any longerCloving your kids sometimes makes you painfulDyoure really happy to love your kids sincerely20The author has written this passage in order to tell us that_.Awe shouldnt allow our children to go to school earlyBsadness is a normal feeling when our children leave usCwe should let our children live independentlyDhappiness is actually as important as sadnessBSitting 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 couldnt 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 Germans feet.Turning to see what snagged his luggage，the American fellow yanked his bag so hard that it crossed over the mans feet.It was then that my horror struck.There was no “Im sorry”，no “Excuse me” and no “Pardon me” coming from this countryman of mine.While this wasnt 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”21In the airport the author and her husband _.Awere talking with a German coupleBwere having a good timeCwere enjoying reading togetherDwere worrying about their flight22According to the author the man with an American accent was_.AstrongBimpoliteChumorousDgenerous23The underlined word “snagged” (in Paragraph 3) means_.AstoppedBcoveredCtouchedDpushed24Every time the author saw Americans bad behavior in China she always felt_.Auneasy and apologeticBscared and disappointedCproud and comfortableDnervous and miserable25From this passage we can know that the author comes
