单元话题导入 [品读话题短文] A Problem in Arithmetic Bill is a good student and an intelligent boy. He likes to① study arithmetic, and he can do all of the arithmetic problems in his book easily. One day on his way to② school Bill passed a fruit store. There was a sign in the window which said, “Apple—Six for five cents.” An idea came to③ Bill and he went into④ the store. “How much⑤ are the apples?” he asked the store. “Six for five cents.” “But I don’t want six apples.” “How many apples do you want?” “It is not a question of how many apples I want. It is a problem in arithmetic.” “What do you mean by a problem in arithmetic?” asked the man. “Well, if six apples are worth⑥ five cents, then five apples are worth four cents, four apples are worth three cents, three apples are worth two cents, two apples are worth one cent and one apple is worth nothing. I only want one apple, and if one apple is worth nothing then it is not necessary for me to⑦ pay you.” Bill picked out⑧ a good apple, began to⑨ eat it, and walked happily out of⑩ the store. The man looked at the young boy with such surprise that he could not say a word.
