One evening, Brownie's family noticed that Brownie hadn't returned home. They went looking for him with no success. Brownie didn't show up the next day, and, although they made their efforts to find him, by the next week he was still missing, Curiously, Spotty showed up at Brownie's house alone, barking and jumping. Busy with their own lives, they paid no attention to the nervous little neighbor dog. Finally, one morning Spotty refused to take "no" for an answer. Ted, Brownie's owner, was continuously disturbed by the angry, determined little dog. Spotty followed Ted about, barking all the time, then rushing toward a nearby empty lot and back, as if to say, "Follow me! It's urgent!" Eventually, Ted followed Spotty across the empty lot as Spotty stopped to race back and barked encouragingly. The little dog led the man to a deserted spot a half mile from the house.

Article: The United States is faced with serious traffic problems. Too many cars travel on the freeways to and from the city. This heavy traffic causes delays and lots of pollution from cars that are using their engines but not moving anywhere. Many cars going nowhere is called a "traffic jam." While many cities in the United States have traffic problems, some of the worst are in Los Angeles, California. Los Angeles is a big city with a large downtown area. One of the reasons why there is so much traffic is that few people use public transportation to get around Experts say one possible solution to the traffic problem in Los Angeles would be to make people want to use the public transportation system of buses instead of their own cars. People say the buses should be made easier, faster, less costly and more dependable than driving a car. One suggestion is to reduce the cost of riding the bus. People who usually drive their cars could save a lot of money on gas and parking costs. Also, Los Angeles could make the buses easier for people to use. The buses could travel to more places in the city. And there could be more special lanes on the freeways that only buses could drive in. These changes would make taking the bus faster and easier than driving a car. Other experts have said that the best way to ease traffic problems is to charge people money to drive on the freeways. These charges, or tolls, would be for the most crowded roads. The tolls would be in effect during the times of day when most people drive to work and home again. These times in the morning and late afternoon are called "rush hour". People would try to avoid driving on these roads, which would decrease the amount of traffic. Also ,the money collected from these tolls could be used to improve the roads and public transportation system.
