One afternoon, I went to pick up my mother from work.I got there a little early, so I _______ (41) my car by a small park, and _______ (42) for her.
As I looked outside the car window, I saw a little boy, around two years old, running _______ (43) on the grass as his mother _______ (44) from a short distance. The boy had a big smile on his face as if he had just been ______ (45) free from some sort of prison .The boy would then fall to the grass , (46) up , without looking back at his mother , run as_______ (47) as he could ,again , still with a smile on his face ,as if nothing had happened.
At that moment, I thought to myself , “why aren’t most adults this way ?” Most adults, when they fall down, make a big deal out of it and don’t even _______ (48) a second attempt. They would be so _______ (49) that they would not try again if someone saw them fall .Or , because they fall , they would find a good _______ (50) for themselves that they’re not fit for it . They would end up too afraid to attempt again for fear of failure.
However, with kids, when they fall down, they don’t consider their falling down as a failure, instead, they treat it as a _______ (51) experience. They try again and again until they _______ (52) .The answer must be that they have not connected“falling down” with the word “failure”. As a _______ (53), they are not discouraged in any way .Besides, they _______ (54) think to themselves that it’s quite okay to fall down and that it’s not wrong to do so. In other words ,they allow themselves to make _______ (55), so they remain energetic.
I was deeply impressed by the boy’s persistence (坚持不懈) and the manner in which he did.

明同学利用A、B两物体、砝码、泡沫等器材探究“压力的作用效果与什么因素有关”的实验.如图

(1)实验中,小明是通过观察   ▲   来比较压力作用效果的.
(2)比较甲、乙两图所示实验,能够得到的结论是:       ▲     
(3)若要探究“压力的作用效果与受力面积大小的关系”,应通过比较图   ▲  
所示实验.
(4)小华同学实验时将物体B沿竖直方向切成大小不同的两块,如图丁所示.他发现
它们对泡沫的压力作用效果相同,由此他得出的结论是:压力作用效果与受力面积无关.你认为他在探究过程中存在的问题是:          ▲            .

材料:玉米的光合效率较水稻的高,这与玉米中磷酸烯醇式丙酮酸羧化酶(PEPC)有很大的关系。如何将玉米的这一种酶转移到水稻等植物上一直是植物生物学家的研究课 题之一。但实践证明,常规杂交育种手段很难如愿以偿。最近,有人利用土壤农杆菌介导法,将完整的玉米PEPC基因导入到了水稻的基因组中,为快速改良水稻的光合作用效率,提高粮食作物产量开辟了新途径。
(1)玉米和水稻很难利用常规杂交手段杂交的原因是                         。
(2)获得PEPC基因后,将其导入土壤农杆菌的质粒中,以获得重组质粒,需要的工具酶
是                         和                     。
(3)玉米PEPC基因在水稻细胞中成功表达的标志是                         ,该过程包括                 和                 两个阶段。
(4)该技术定向改变了水稻的性状,这在可遗传变异的来源中属于___  _____。
