What’s the most important thing for you to have in your life? Somebody mentions hard-work, others suggest knowledge, love and luck.

　　If you arrange the 26 English letters alphabetically(按字母表的顺序)and use numbers to represent each of them, for example, 1 for a, 2 for b, 3 for c…, you can change an English word into a number. So hard-work becomes 8+1+18+4+23+15+18+11=98, meaning 98 is its mark; knowledge: 11+14+15+23+12+5+4+7+5=96, while love: 12+15+22+5=54, and luck: 12+21+3+11=47, a small mark. None of these words can give one a full mark. What about money? It can’t , either.

　　Then what else? Don’t be worried. You can always find an answer to a problem in your life, when you change your way of looking at things or doing things, or your attitude. Yes, attitude is the word. See for yourself: attitude:1+20+20+9+20+21+4+5=100，a full mark.

　　Most times people hope for a better life. It is possible if you will have a change for the better after you have changed your attitude. When you change your manner and become friendly to others, you’ll meet more smiling faces towards you.

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___  _____。
