判断下列句子是否符合短文内容,符合的用“T”表示,不符合的用“F”表示。 Two fishes once lived in a small pond. A frog arrived at the pond and made it his home. Soon the fishes and the frog became close friends. One day, the friends heard a group of fishermen talking.'This pond seems to have plenty of fish. Let us come tomorrow and cast (撒网) our nets. We shall have a good catch.' When the frog heard this, he was worried.'Dear friends,' he said,'it will be clever for us to leave the pond. Tomorrow may just be too late.' The two fishes laughed at his fears.'Don't be upset by the fishermen's words. They may not come here at all. Even if they do come, we need not fear. We shall use our wits (才智) together and save ourselves.' The frog was not satisfied with these words.'I am not as clever as you two are. I cannot continue to live here. I will leave the pond tonight. I wish you good luck,' he said as a parting (分手) message. True to their words, the fishermen arrived early the next morning and cast their nets in the pond. All the creatures who lived in the pond were caught in the fishermen's net. Not a single one of them escaped. The two fishes tried all the tricks (伎俩) they knew to get out of the net. The net was strong and they could not manage to escape. (     )1. The frog and the two fishes became close after the frog moved into the pond. (     )2.
