Last weekend I was out walking with my dog. She loves wandering around and seeing we meet, so it becomes a social walk rather than an exercise. Then we 0ur neighbour who was preparing to sell her house. She was busy getting ready for her open house（看房时间）that afternoon . After talking a little we went our separate ways .I could tell it was a(n) day for her. After I got home, I quickly some of the wonderful lavender（薰衣草) in my garden Wonderful! They smelled good and the purple were so pretty. I wrapped some packing paper around the bunch and it to my neighbor for her open house. I loved her expression she saw me there with a bunch of lavender! It made me happy. It made her stop and take a deep and maybe reduced her stress for a second The next day I had a note in my mailbox from my neighbor thanking me for my . She said everybody commented on how wonderful her house smelled She said the 0f kindness I showed helped some of the stress she was feeling. Her note was like a big hug to me. Never that it's the gift from the heart that is the most .I think sometimes we hesitate（犹豫) to do the acts of kindness because we may think they aren't anything but actually they are probably the best gift

标准状况下，向100 mL NaOH溶液中缓慢通入一定量的CO2气体，充分反应后，测得最后所得溶液M的pH＞7(反应前后溶液的体积变化忽略不计)。在溶液M中逐滴缓慢滴加1 mol/L盐酸，所得气体的体积与所加盐酸的体积关系如图所示：
已知图中B点位置固定，V(B)="300" ml。，而点A、C可在各自的轴上移动。
（1）原溶液的物质的量浓度为 mol/L，B点时，最终所得溶液中的溶质的物质的量浓度是 mol/L。(两种溶液混合时体积可以直接相加)。
（2）V(A)的取值不同时，溶液M中的溶质的成分也不同，请填写下表：
| V(A)的取值 | V(A)=0 | 0<V(A)<150 | V(A)=150 | 150<V(A)<300 |
| 溶质的成分 | ① | ② | ③ | ④ |
