Now cities are full of cars. Some families even have two or more cars. Parking is a great problem, and so is the traffic in and around the cities. Something will have to be done to change it. What will the cars of tomorrow be like? Little cars may some day take the place of today's big cars. If everyone drives little cars in the future, there will be less pollution in the air. There will also be more space for parking cars in cities, and the streets will be less crowded. Three little cars can fit in the space now needed for one car of the usual size. The little cars will cost much less to own and to drive. Driving will be safer, too. What is more, these little cars can go about 65 kilometers per hour. Little cars of the future will be fine for getting around a city, but they will not be useful for long trips. If big cars are still used along with the small ones, two sets of roads will be needed in the future. Some roads will be used for the big, fast cars, and other roads will be needed for the slower small ones. Little cars are very fine for   _  . A) long trips B) journeys C) everyday life D) sport

Once upon a time there was a wise man who used to go to the sea to do his writing. He had a habit of walking on the beach before he began his work. One day he was walking along the shore. As he looked down at the beach, he saw something moving like a dancer. He smiled to himself at the thought that someone would dance on the beach. So he began to walk faster to catch up.As he got close,he saw that it was a young man and the young man wasn't dancing,instead he was reaching down to the shore,picking up something and very gently and throwing it into the ocean. As he got closer he called out,"Good morning!What are you doing?'' The young man paused ,looked up and replied,"Throwing starfishes into the ocean." "I guess I should have asked ,why are you throwing starfishes into the ocean?" "The sun is up and the tide is going out.And if I don't throw them in, they will die." "But ,young man ,don't you realize that there are miles of beach and starfishes all along it. You can't possibly make a difference!" "The young man listened politely.Then he bent down ,picked another starfish and threw it into the sea ,and said ,It made a difference for that one." The wise man was lost in thought when the young man kept trying. Yes, there is something very special in every one of us. We have all been gifted with the ability to make a difference. And if we can know that gift, we will gain the power to shape the future.Each of us can do something for the future,each of us must find our starfish. And if we throw our starfishes wisely and well,the world will be better. The wise man was lost in thought because  _  . A) he realized something new and important B) he had a good story for his next writing C) he worried the lives of so many starfishes D) he agreed to save all starfishes on the beach
