为了研究圆柱体浸入水的过程中水对容器底部的压强情况，某小组同学选用高度H、底面积S均不同的圆柱体A和B进行实验．如图所示，他们设法使圆柱体A逐步浸入水中，测量并记录其下表面到水面的距离h及水对容器底部的压强p，接着仅换用圆柱体B重新实验，并将全部实验数据记录在表一中（实验中容器内水均未溢出）．

表一：

    I had introduced myself to others by saying, “Hi, I am J's mother” or “A's mom” rather than my own name. Another mother 1 asked me, “And do you have a(n)2?”

    My friend 3 me a few days before. I kept on talking for five minutes about my 4 When I 5 she asked, “So, is there anything going on with 6?”

    At first, I didn't understand 7she was asking me that. Hadn't I just told her what was going on with me? But then I realized that 8 I said had actually been about myself. It was all about my kids. I love being a mom. The kids were my world.9 it was my kids' world, and I just lived in it and 10it didn't fall apart.

    The phone call with my friend made me 11 that I needed to start thinking about who else I am 12 being a mother. I realized that to be a good 13 I also had to be my own person-not just someone who only 14 to take care of other people.

    I joined a club and started doing some volunteer work. I took a writing class online. I am now a regular 15to several magazines and write a monthly blog. I don't make a lot of money by writing, but I feel more 16 as a person. I am 17 and growing, and that makes me more 18 and a better mother.

Now when I 19 myself, I say, “Hi, my name is Randi,” and it feels 20 to be me.

    To breed snails (蜗牛) well, you need to spray water to the container every morning and evening, change soil every two weeks, and feed them with cabbages and sweet fruits—this is what Sun Youxiang, a fourth-grade primary school student in Hangzhou____(conclude) after breeding snails for one year.

    From three small white snails at the very beginning____more than 60 snails of four generations now, he has done a great job in his assignment for his science class____(witness) the reproduction of animals is a precious experience for kids. Their____(create), patience, and respect for life will be stimulated (激发) as they learn to take care of animals on their own.

    Sun's teacher said the assignment served as a good example of life education. Practice____(be) an essential step in leaning, which will benefit the kids for____life time. Life education allows kids to know how to live with nature and creatures in a friendly way.

    Starting from this year, Science will become an____ (equal) important subject as Chinese and Math in primary schools____aims to improve students' knowledge about the surroundings____(draw) by curiosity, more kids will be willing to observe and think through practicing, which will add to____(they) recognition of the world in the long run.
