【题目】Peter wondered why he didn’t have many friends. The reason was that he was always taking, never giving.

One day Peter told Bill, "I’d like to give a party on Saturday. I’d like you to come and bring Martha, too.

"Thanks, Peter. We’d be happy to come. ""Perhaps you’d like to bring your violin. You and Martha sing well together. I’m sure everyone will want you to sing for us. "That was how Peter began to plan his party. Next, he asked another friend, Betty, to bring a cake. "You make the best cake in the world, Betty, and I like to eat your cake better than have one from the bakery. "Peter invited a few other friends to come to his party. He didn’t forget to ask something from each one of them. He even asked Jim and Mary Jackson to let him give the party at their house! They agreed.

The party was a big success. However, as the guests were leaving, they said "Thank you. "to Bill and Martha for the music, Betty for the cake, the Jacksons for the use of the house and to others for their hard work. To Peter they just said, "Thanks for the invitation.

【题目】Have you ever wondered how and why a fall leaf changes color? We first have to understand what leaves are and what they do.

Plants are the world’s food factories. Plants take water from the ground and take CO2 from the air. Plants use sunlight to turn water and CO2 into glucose(葡萄糖). Glucose is a kind of sugar. Using it as food, plants get energy and grow. Plants using sunlight to turn water and CO2 into sugar is called photosynthesis(光合作用). ChlorophyII helps photosynthesis. It gives plants their green color.

As summer ends and autumn comes, the days get shorter and shorter, and trees "know" to begin getting ready for winter. During winter, there is not enough light or water for photosynthesis. Trees rest during this time and live on the food they store during the summer. They begin to shut down their food making factories. As the green chlorophyII disappears from the leaves, we begin to see yellow and orange leaves. These colors have been in the leaves all the time. We just can’t see them in the summer, because they are covered up by the green chlorophyII.

The bright reds and purples we see in leaves are made mostly in autumn. In some trees, glucose is caught in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn turn this glucose into a red color. The brown color of trees is made from waste left in the leaves. It is mixture(混合物) of all these things. It makes the beautiful leaves during autumn.
