Прочитай рассказ и подчеркни в рабочей тетради правильные ответы в скобках.
One day Father rabbit went to the forest (лес). He needed (some/how much) food for his family.
He went on and on (шёл и шёл) and didn't find (any/some) food. In the end (в конце концов)
he found (some/any) apples under an apple tree. "OK," he said. "There are not (many/much)
apples here, but it's late and I must go home." He put the apples in the bag and ran home. On his
way (по дороге) he met a bear. "What do you have in your bag?" the bear asked. "There are
apples in my bag," said the rabbit. "I would like (some/a) apples," said the bear. "Sure! (Here
you are!/Yes, please.)" said Father rabbit. He gave (some/very few) apples to the bear and went
home. Then he met a hedgehog. The hedgehog was very hungry. "Would you like (some/any)
apples?" the rabbit asked. "(Here you are!/Yes, please.)" said the hedgehog. "Thank you very
much."
Then Father rabbit met a fox and gave it (some/any) apples too. And then he looked into his bag
— it was empty (пустой).
The rabbit came home. He was tired and very sad. He didn't bring (some/any) apples. Mother
rabbit opened the door and said, "Would you like (some/a) milk or (some/a) berries?"
Father rabbit couldn't understand, "But who brought this food?" he asked.
Mother rabbit said, "You went to the forest. The little rabbits were very hungry. We didn't have
(very little/any) water, we didn't have (any/very little) vegetables. Then a bear came and
brought us (some/how much) honey. A fox came with (a/some) milk, and a hedgehog came
with (any/ a lot of) berries."
"Now we have (very little/a lot of) food. It's wonderful," said Father rabbit.
Mother rabbit said, "You are wonderful and now we have (any/a lot of) friends too."
