When responding to any adult, you must answer by saying “Yes ma’am” or “No, sir.” Just nodding your head is not acceptable.
Because I grew up in rural North Carolina, this rule comes    36   to me, and it seems the obvious choice to come first. If you want children to respect you, you have to let them know    37 . Simply telling them you want them to address you by saying “sir” lets them know   38     you expect them to treat you. I also tell my students it’s a very useful tool when    39  with adults, and furthermore it also     40   handy for any adult interacting with another adult. Case in point: I was   41    the phone recently with the phone company discussing the inaccuracies(差错) of my    42  . The lady I spoke to was not 43   and seemed annoyed.    44  , in the midst of the conversation, I threw in a “yes, ma’am,” and her entire  45  changed. She became far more helpful and   46  to deal with, and she   47  cutting my bill in half.
Some of my students in Harlem were to be   48  for a chance to attend a high-rated junior high school. The school only had thirty openings for the following year, and twelve of my students were   49  the many kids across the city who applied for the spots. I practiced what the interview would be   50  with my students, and one main thing I stressed was, “  51  you say ‘yes ma’am’ or ‘no sir’ no matter what!” Weeks after the interviews, I was delighted to hear that all twelve of my students had been   52  . When I talked with the admissions director at the school, the main   53  he made over and over was how   54   my students were in their interviews. It seemed like just such a simple thing to do, but it gets   55  .

小明在化学实验室发现盛放氢氧化钠溶液的试剂瓶瓶口和橡皮塞上出现了白色粉末,于是就叫来小军和小红共同探究这种白色粉末的成分.他们依据所学的化学知识,对这种白色粉末的成分做了如下猜想:

(1)①可能是NaOH   ②可能是Na2CO3 ③可能是 _______________ .为了验证猜想,他们分别做了如下实验:

(2)小刚取少量白色粉末,向其中滴加稀盐酸,有气泡生成,由此小刚认为白色粉末是碳酸钠,小刚的结论是否正确? _______ ,理由是 _______________________________

(3)小军取少量白色粉末配成溶液,向其中滴加酚酞试液,溶液变为红色,由此小军判断白色粉末为氢氧化钠,小军的结论是否正确? _______,理由是 _______________________________

(4)小红取少量白色粉末配成溶液,向其中滴加氯化钡溶液,有白色沉淀产生,由此小军判断白色粉末中有 ___________.为了验证猜想③,小红继续向溶液中滴加氯化钡溶液,至不再产生沉淀,小红这样做目的是_______________________ ,然后过滤,你认为她接下来还应进行的实验是 _____________________ ,在小红所做的实验中,若把氯化钡溶液换成氢氧化钡溶液是否可行? ______ ,理由是 _________________________.(用化学方程式表示)
