    Never try to work when you are very hungry. If you want to do your homework right after school, you
may want to eat something before getting to work. ①Always do your homework before you get too tired.
Don't wait till very late in the evening, or your homework will seem much harder than it really is. If you
have more than an hour's work, you should give yourself ②a break after an hour. On the other hand, ③you
should work at least half an hour at a time without stopping.

    Don't put it off (推迟) until the last minute. If you put off doing your homework, you will have it on your
mind, and you won't enjoy your free time so much. If you put it off until the end of a week or until right
before a test, you will have too much to do. A little each night, enough to keep up with (跟上) what is
happening each day in school, will take the fear out of tests and keep you on top of it.

Foolish(silly) Freddie lived in a small village. The people of the village laughed at him. They liked to show visitors how silly Freddie was. They thought this was a funny thing to do.
One day, a visitor came to the village.
"Watch this", a villager said, and called to Freddie. "Come and play a game, Freddie, " he shouted. Freddie walked slowly towards him, a silly smile on his face.
"Look! Freddie, "the villager said, "I’ve got something for you." He showed Freddie a dollar coin and a much larger 50-cent coin."Which would you like?" he asked Freddie.
Freddie took the 50-cent coin at once.
The villager laughed."See how foolish he is," he said."He always does that. He’s too silly to learn anything." He walked away, leaving Freddie with the visitor.
The visitor felt sorry for Freddie and said to him, "Although the 50-cent coin is bigger than the$1 coin, the$1 coin is worth(值) much more.Two times as much."
"I know that," Freddie said."But once I take the$1coin, they’ll stop playing the game."

(8分)材料   苏云金芽孢杆菌生长到一定阶段,菌体内一端形成芽孢,另一端形成一种被称为伴孢晶体的蛋白质晶体。菌体破裂后释放出芽孢和伴孢晶体,伴孢晶体本身并无毒性,是毒素的前体。当昆虫吞食伴孢晶体后,在肠道内碱性环境条件和特定的蛋白酶的作用下,伴孢晶体变成毒素分子,能使小肠上皮细胞萎缩退化,昆虫停食,最后脱水死亡。科学家利用苏云金芽孢杆菌的这个特性,在实验室大量培养,制成生物农药,洒在农作物上,让害虫吃后中毒死亡。或利用基因工程技术,把苏云金芽孢杆菌的抗虫基因转到农作物体内,培育出抗虫品种。请根据上述材料回答下列问题:

(1)上图中,切断a处的工具酶是____________ ,切断b处的酶是             ______。
(2)作为目的基因载体的细菌质粒往往要带有一个抗生素抗性基因,该抗性基因在基因工程中主要用于_____________________________________________________。
(3)苏云金芽孢杆菌的抗虫基因导入棉花细胞是否表达,最简便的检测方法是________________________________________________。
(4)苏云金芽孢杆菌的抗虫基因转到农作物体内后,也能产生伴孢晶体蛋白,说明___________________________。
(5)转基因工程改良动植物品种,最突出的优点是_____________________________ 。
