阅读理解。 Today we will talk about expressions with 'apple'. 'Apple pie order' means very well organized. Nobody is sure when and where this expression began. It is said that the women of New England loved to have everything in its place, especially when they were making apple pie. Another expression 'apple of discord' describes the opposite condition. The ancient story says that all the gods and goddesses were celebrating a marriage when Discord, one of the gods, threw a golden apple on the table which was to be given as a prize to the most beautiful goddess. How could they choose among Juno, Minerva and Venus? When Paris decided to give the golden apple to Venus, Juno and Minerva were very angry and threatened(威胁)him. This began the long Trojan War. Calling a tomato 'a love apple' was a mistake. In the sixteenth century, Spain imported the tomato from South America to Morocco, and then Italian businessmen took it to Italy. The Italian name for the tomato was pomo di Moro-apple of the Moors(荒野). When French growers imported it from Italy, they thought di Moro meant d'amour, the French word for love. And so pomo di Moro became the apple of love. People believe many things about the apple. One belief is that it has great powers of keeping people healthy. 'An apple a day keeps the doctor away.' Another belief is based on fact. 'One rotten apple spoils the barrel.' The expression has come to mean that one bad person in a group can cause everyone to act badly. 1. Which of the following expressions means badly organized? A. Apple pie order. B. Apple of discord. C. An apple a day keeps the doctor away. D. One rotten apple spoils the barrel. 2. Which of the following statements is WRONG? A. Discord is the name of a god. B. Di Moro means love in Italian. C. 'Apple pie order' means very well organized. D. Many people believe apples can keep them healthy. 3. We can most probably hear this passage in a radio program about ______. A. famous people in America B. traveling in America C. eating in America D. words and their stories
