单选题{{B}}B{{/B}} Water, water everywhere. It lasted almost two months, but in August it ended. It left 45 people dead and $10 billion worth of damage in nine states of USA. It was quite a big Mississippi flood ever recorded. In St. Louis, Missouri, 9,000 people were forced to leave their homes while the city was in danger. St. Louis is just downriver from the points where the Missouri and Illinois Rivers flow into the Mississippi. All three rivers were flooding. But the city escaped the worst when levees (堤) broke upriver. A levee is built of fiver sand and clay (粘土). Eleven miles of flood walls were built in the late 1960's. The walls are 18 inches thick and 5 to 22 feet high. They were designed to protect against a 52-foot flood. In St. Louis, water almost reached the top of flood wails. It measured 49.4 feet.

单选题Everywhere in the world, plants and animals live together. Some animals eat plants they live with. Some plants stay alive because many plant-eating animals have natural enemies that eat them. Rich soil for the roots of plants is produced by worms and other very small animals that live underground. Green plants feed animals and people. It takes all the plants and animals living together to keep the earth a good place to live in. Plants and animals trade with each other. They trade for things they both need to stay alive. Animals breathe and the air gets changed inside their bodies. When they breathe the air out again there"s something called carbon(碳) in it. Animals can"t use this air again. But plants need carbon. The plants trade fresh air for the carbon they need. Plants make food from carbon and water. They use sunlight for this work, just as a machine uses gas or electricity to keep running. The plants store the food they make inside themselves. But what do the plants get in return? Many things. Plants make food from the carbon and other things that come from animals" bodies. Insects like bees carry pollen(花粉) from one flower to another and the pollen forms seeds. Birds and other animals eat the fruit in which seeds grow and often drop the seeds where they can grow up into new plants. So animals help the growth of new plants.

单选题I might be letting my young son watch too much television. I am certainly watching too many of his programs. They can really be perplexing as they force you to think of the mysteries of life. For example, when Franklin (the turtle) wanted a pet, his parents didn't want it to be a frog. They felt that frogs belong in a pond. Isn't that where turtles belong? And why is it that Little Bear's animal friends can all talk and behave like people, but his friend Emily has a dog that can only bark and fetch? Tell me that isn't a mystery! Dog lovers can be reassured by Kipper and his friends. These dogs are very human. However, the only time they wear clothes is when they put on bathing suits to go swimming. I'm confused! Speaking of dogs, could Pluto ever be Goofy's pet? I don't get it! What did the great Mr. Disney have in mind? And it is a mistake! The other day we watched a very nice little pig setting up a picnic. One of the foods was a big ham. Could it have been a soy ham? Is there such a thing? I hope so! Another thing that bothers me: What if Elmo isn't real? He can't be a mere puppet! He's got a better attitude than most people. I just keep wondering. I think we'll turn off the TV and go out for a walk. Maybe we'll run into that mouse who dresses well but certainly doesn't speak as clearly as the one in TV.
