　　feed the world

　　A food scientist is discussing the main types of food crops.( S=scientist; I=interviewer)

　　I: One of the most important food crops in the world of course is rice. Why is it so important?

　　S: Well, for one thing, everyone can eat it, and it’s suittable for sick people and young children.

　　I:Is it grown all over the world?

　　S: No. It needs a hot climate and lots of water.So it can’t be grown in cold countries or where there is little water. But where the conditions are right, you can grow three rice crops in a year.

　　I: Can you live on rice alone?

　　S: No.It doesn’t contain all the foods a body needs to stay healthy.Also it’s better to eat the whole grain, but in many parts of the world it’s the custom to remove the brown outside part of the grain. I: What about the potato?

　　S:Well,the potato is a very good food for the human body. So you could live for six months just by eating potatoes. In a year, you would also need to eat a little fat and some fresh fruit to stay healthy.

　　I:Where are potatoes grown?

　　S:They can be grown in cold countries , like the north of Europe and up in the mountains of South American , where the potato came from.

　　I:What about bread?

　　S:Bread can be made from different grains. It’s an important food in the north of Europe where it’s cold but also in the Middle East.It’s a very good food,but you need to eat other foods like fresh fruit and vegetables to stay healthy.

　　I:Are there any other foods we haven’t mentioned?

　　S:Yes, there’s Indian corn. This came from America, but is now a very important crop all over the world. You need a warm sunny climate to grow maize , but it doesn’t need as much water as rice. Mind you, if you water your maize, you will get a better crop.

　　I: And we haven’t mentioned noodles.

　　S: No. Very important!Noodles and pasta are both made from a type of hard grain . thje grain is turned into a powder, mixed with water and then formed into different shapes. In Asia and the Middle West these are called noodles and in Italy these are called pasta.

　　II.完形填空精品：(這篇完形語境較強， 情節(jié)曲折，文法地道，如果學(xué)生能背誦下來，效果更好)

　　“I’ve been writing a book, John. Do you think anyone would be interested in 1 it?” said the old lady.

　　John took 2 the papers from her shaking hand and 3 her in a chair. He remembered her rich 4 in the early days of the Old West. He looked through the papers, “It’s good, Grandma.” he said gently. Then realizing that she couldn’t hear him, he shouted 5 her ears. “I think it s very good. I’ll 6 it to a publisher.”

　　Ten days later, he reported that the publisher had had time to read only a few pages. But he was so impressed that he had sent $100 for an option (版權(quán)). 7 money would be given as an advance. Every month John brought $100 for her with a letter from the publisher telling about the 8 of the book.

　　One morning, three months after her 100th birthday, Grandma didn’t get up. The doctor told her that she couldn’t 9 more than a few days. She was 10 to go, but she first wanted her book to be in 11 . John promised that she would get it very soon.

　　Grandma 12 on until the day the book came into her hands, with the title and her name on the cover. Though she couldn't see it, she could 13 it. She 14 traced (探查) her name with her fingers, tears in her eyes. Two hours later. She died peacefully, still holding her book. Her granddaughter took up the book and opened it. “Why, it’s just blank pages!” she cried in 15 .

　　John's face turned 16 . Then the girl understood. There never was a book. Grandma couldn’t hear the little bell when the typewriter came to the 17 of the line. She would keep on working, not 18 the whole sentences and sometimes the paragraphs were 19 . John did not tell her, for he couldn’t take away her only 20 . It was John himself who had written the letters and sold his car to pay the advance.
