（18分）某工厂废水中含游离态氯，通过下列实验测定其浓度。

①    取水样10.0mL于锥形瓶，加入10.0mLKI溶液（足量），滴入指示剂2—3滴

②    取一滴定管依次用自来水，蒸馏水洗净，然后注入0.01mol/L的Na₂S₂O₃溶液，调整液面，记下读数。

③    将锥形瓶置于滴定管下进行滴定，发生的反应为I₂+2Na₂S₂O₃=2NaI+Na₂S₄O₆

请回答下列问题：

（1）      步骤①加入的指示剂是              

（2）      步骤②应使用      式滴定管

（3）      步骤③当待测液由           色变为         色且半分钟不变化即达终点，若耗去Na₂S₂O₃溶液20.0mL，则废水中Cl₂的物质的量浓度为             

（4）      从实验操作步骤上看，氯气的实际浓度比所测浓度         （填“偏大”、“偏小”或“相等”）

     I consider myself one of the luckiest people I know.

     I lost my biological mother when I was 9 and when she was alive she was not much of a mother to

me.

     I met my step-mom for the first time when I moved to America to be reunited with my father. From

the beginning she made sure to let me know that I was safe and welcome.

     I remember when I first saw her at the airport. It was different but not uncomfortable. After I was

picked up from the airport we went home and she unpacked my luggage. Then she took me shopping

for new clothes since the ones I had brought with me from Africa were a bit worn.

     That night before I went to bed she came to my room, which was the first room I had ever had for

my own, with the first bed I didn't have to share. She told me she was glad to have me and that she

would take good care of me.

     Before she walked out of my new room, she asked me for a hug. I had no idea what she was talking

about. I did not know what the word hug meant, not because I didn't speak English, but I had just never

heard the word before, let alone knew what it meant. So, I just looked at her with a questioning

expression on my face.

     But she didn't give up. She called my father into the room and asked him to explain to me what she

meant. When my father was explaining I looked at her and wondered why she wanted to hug me. She

then told me it was because she loved me and opened her arms wide. Shyly I opened mine and we

hugged.

     That was my very first hug and I was 11 at that time. I'm 23 now and, thankfully, I have received

many hugs since then.

     I consider her my birth mother because life began when I came to stay with her. For the first time

there were no kids for me to take care of and I became a child for the first time. There was no work

waiting for me every day other than the occasional chores that she gave me to teach me responsibility. 

     Today I say thank-you to my mother; thank you for giving me my childhood back after it had been

taken away from me. I am who I am today because of your love!
