     Parents are the closest people to you in the world. They love you just

because you are you. And they would do anything for you. Like a lot of

middle school students, Zhuang Shuxia has a problem. She and her parents

don’t get on well.

     "I really want to be my daddy's little girl. But it feels like he just doesn't

understand. He just says something to me and doesn't listen,"said Zhuang, a

Junior 3 student in Shijiazhuang, Hebei.

     Do you and your parents also have problems?

     Well, why don't you all take a walk and have a talk on Saturday? It's the

International Day of Families. On May 15, people around the world give

thanks for good things about their families and work on family problems.

problem as Zhuang's family: The children, 12 to 15 years old, didn't like

talking with their parents much. They weren't happy at home.

     Of course, lots of kids feel that way. But you and your parents will be

much happier if you can be friends. Here are some ways to have a good talk with them:

     ◆ Find a good time to talk, like when you're eating dinner, going out for a walk or watching TV.

     ◆ Tell them something you're interested in, or ask them about their lives when they were young. They love to talk about it.

     ◆ Listen to them carefully, and look them in the eye.

          B. They should take a walk and have a talk with their parents.

          C. They should do something to celebrate the International Day of

Families.

          D. They should help others to solve their family problems.

     3. How does the writer know 1,500 families had the same problem as

Zhuang's family?

          A. From a study made in Beijing.

          B. From reports about family problems.

          C. From discussions with parents and their children.

          D. From a report on the International Day of Families.

     4. Who may be the best readers of the passage?

          A. Scientists        

          B. Teachers          

          C. Teenagers        

          D. Parents

美丽的青海湖不仅让我们感受到自然之美,当地的居民还能从青海湖内“冬天捞碱、夏天捞盐”。当地学校的某化学兴趣小组对捞出来的纯碱进行研究,有的同学认为捞出来的全是碳酸钠,有的同学认为捞出来的纯碱中混有少量的氯化钠。现在他们准备以一包冬天捞出来的纯碱(若含有杂质,只考虑为氯化钠)为研究对象,探究该纯碱样品中碳酸钠的质量分数。小组通过讨论设计了下图中的装置,请你参与探究。(实验前活塞都关闭)

【实验一】称取13.25g纯碱样品完全溶于水,放入甲中,称量丙装置的质量为355g,打开

b、c,甲中现象为       时,再称量丙装置的质量为350.6g,通过计算得出纯碱样品中

碳酸钠的质量分数为  。甲和丙中反应的化学方程式为                    

同学们通过讨论认为上述方法并不能准确测量,其理由可能是       。(写一条即可)

【实验二】通过讨论,改进后的实验步骤如下:

①称量丙装置的质量。

②称量样品,检查装置气密性。

③关闭a,打开b,注入足量的稀盐酸。

④打开a、d,鼓入氮气一会儿。

其正确顺序为          (填字序号,可重复)。

【表达与交流】

(1)此实验中丁装置的作用是                    

(2)此实验中鼓入氮气的作用是                           。(2分)
