Long, long ago there lived 1 rich king. His name was 2 Midas. He was 3 greedy man and liked_4_gold very much. One day he asked gods of_5_Greece to give him 6 more gold. 7_gods decided to punish him and said: "Very well; in 8 morning anything that you touch with your hand will become 9_gold." 10 Midas was very happy when he heard this. "I shall be 11 richest man in 12 world," he thought.

When he got up early 13 next morning and touched his bed, it became 14 gold. He began to dress and his clothes became 15 gold too. Midas loved 16 flowers very much and he had 17 beautiful garden. Before 18 breakfast he went out into_19_ garden to have _20_look at his flowers. 21 day was fine, _22 sun was shining brightly in 23 blue sky, _24 trees were in 25 blossom

and 26 flowers looked beautiful.27 king took one of 28 flowers, but it

became_29_gold in_30 _ his hand. He was sorry that _31 flowers changed as soon

as he touched them. _32_king went to have _33_breakfast. He took_34_cup of 35 sweet milk, but 36 milk became _37_gold at once. Then he took 38 piece of 39 bread, and 40 bread also became 41 gold. 42 Midas no fel unhappy. It was good to be 43 richest man in 44 world, but he was hungry and he could not eat_45_gold.

Midas went out into 46 garden again. His little daughter was playing there. When she saw her father, she ran up to him. Midas kissed his daughter and 47 little girl became 48 gold statue.

Midas was very unhappy now. His eyes were full of 49 tears, but 50 tears also became 51 gold. He asked 52 Gods to take away this "Golden Touch" "It was very foolish to love 53 gold so much" he said. "Take all my gold and give me back my 54 daughter"

"Go",- said_55_gods, "and wash 56_ your hands in 57 river which is near your

garden, and 58 water will take away 59 "Golden touch".

Midas went to river and washed his hands in it. Then he quickly ran up to 60 gold statue of his daughter and kissed her again. She at once changed back into 61 beautiful little girl. Midas cried with_62 joy. He never forgot this 63 lesson. He knew that 64 gold did not give 65 happiness.

Д.Болз профессор, директор школы ,консультант по учебным программам г.Венечи (штат Вашингтон ,США),считает: "Если учитель знает нужды учеников ,если он использует их сильные стороны либо старается помочь им преодолеть слабые,процесс обучения изменится коренным образом.Во-первых,ученик добивается больших успехов,когда использует сильные качества,во-вторых ,ему помогают ликвидировать свои недостатки без чувства стыда и огорчения.Ученики становятся более уверенными и компетентными". Согласны ли вы с точкой зрения Д.Болза?Какие ещё факторы,на ваш взгляд,влияют на успешность процесса обучения?
