Q: In spring, you may have seen white foam on a green tree or other plants. As a matter of fact, the foam is where young spittlebugs live. These insects are protected by the foam, and they usually don't do much harm to the plants. As we all know, in late summer, a mother spittlebug lays her eggs on the plant. The babies will hatch in spring. After they come to the new world, they begin to eat juice from the plant. The babies eat more juice than their bodies need for food. The extra juice mixes with a special waste that the spittlebugs produce. When this fluid is released, it mixes with the air, forming bubbly foam. What is so great about having a foam home? The space inside is so wet that it can keep the bugs' soft bodies from drying out. And the foam tastes bad, so it keeps away most animals that would eat the bugs. Some birds will reach their heads through the foam to find the bugs. Wasps and ants might eat them, too. But most of the bugs stay safe inside the foam. Once the bugs have grown into adults, they stop making foam. They leave their homes and jump from plant to plant in search of food. The adults look a little like tiny frogs. For this reason they are also called froghoppers. If you see some foam on a plant, you might want to take a careful look inside. Gently push some of the foam aside with a small stick. Deep inside you may see a few insects eating plant juice. They might also be making more foam. Be sure to push the foam back after a moment to cover the insects and keep them safe. Soon the spittlebugs will grow up and leave their foam home. They will join the other insects in the grassland. According to the passage, the white foam _ . A) does much harm to the plant B) protects the plant from being harmed C) is where a mother spittlebug is living D) is plant juice mixed with spittlebugs' waste and the air

Q: Chrysanthemums are to the fall what tulips are to the spring. In ancient China, chrysanthemums (or 'mums' for short) were first planted thousands of years ago. People chose the chrysanthemum as their Flower for October, a symbol of the rest and ease that followed the season's final harvest. Then they symbolized a scholar in retirement and were one of the four noble plants, along with bamboo, the plum flower, and orchid. The Japanese hold the chrysanthemum as a symbol of the sun. They consider the orderly unfolding of its petals to be a symbol of perfection. They also think that a single chrysanthemum petal placed in the bottom of a wine glass encourages a long and healthy life. The Japanese even have a National Chrysanthemum Day on September 9, known as the Festival of Happiness. In the United States during colonial times, its popularity grew such that mums now reign as "Queen of the Fall Flowers." Mums remain the most widely grown pot plant in the country and the largest commercially produced flowers. Chrysanthemums generally represent cheerfulness and rest. So they are welcomed throughout the British Isles and North America for any occasion, such as football games and parties. In other countries such as Italy, Belgium and Austria, however, their association with the dead makes chrysanthemums acceptable only for funerals and graves. The Japanese consider the chrysanthemum as a symbol of the sun because _ . A) people like the flower just as they like the sun B) the flower with its nice petals represents a symbol of perfection C) people find the flower having no perfect petals when it is unfolding D) the flower unfold its petals orderly just like the sun

Q: In December of l 992.I was a happy husband and father of two young children.A month later,I was diagnosed with Acute Lymphoblastic Leukemia . After two years of chemo that helped control the disease,my body was weak and lifeless.I felt as if I were a puppet who needed help to lift his arms or hold up his head. I began to run.After six months my strength had come back.On one of my runs,one where I felt I could run forever,I decided I was going to try to run a marathon. After telling my Dad about my plan,he told me of a program that trains people to run a marathon,while raising funds for Leukemia research at the same time.So that summer,through the Leukemia Society's Team in Training program,I started to train for the Marine Corps Marathon.During mile after mile of uncertainty,the day finally came to run the marathon. On October 27,1996,at 8 A.M.,along with l9,000 other brave souls I started on a 26.2-mile journey that I will never forget. I first saw my wife Patty at the six-mile mark .

That thought alone pulled me forward.Mile 22,23,slowing but going,24,25,then there it was.The Iwo Jima War Memorial.I have seen nothing so grand and inspiring in my life.Three hours and forty-one minutes after I started,I crossed what I think has to be the most fitting finish line in all of road racing! That night the Leukemia Society gave me a pin at a post-race party that simply says,"Leukemia 26.2". If God wills,my cancer may once again take away my hair and my strength,maybe even my life.But it can never take away my pin,or the fact that I am a marathoner .
