【正文】 r land. Now scientists think that water hyacinths can be useful. The plants are really a free crop. No one has to take care of them. They just grow and grow and grow. What can farmers use them for? Some fish like to eat them. Farmers can grow these fish in the lakes and rivers. Workers can collect and cut the plants with machines. Then they can also make fertilizer to make their crops grow better. They can also make feed(飼料 ) for their farm animals. Maybe it will be possible to make methane gas(沼氣 ) for energy. (We burn gas from petroleum(石油 ) for energy. Methane gas can be made from plants.) Then poor tropical countries will not have to buy so much expensive petroleum.

On May 16, Guo Ruiting, 14, from Shenzhen Foreign Language School, had a big debate (辯論 ) with her classmates on this topic. Guo believed that making the scores public would make students study harder. At first, she explained many theories (理論 ) that she had collected from the Inter. But they were too difficult to understand. So she was easily beaten back by her opponent (對(duì)方 ) Du Xiaoshi. “ Making the results of our tests public is bad for us,” said Du. He came to this conclusion (結(jié)論 ) after he failed his history exam one month ago. He thought it was just an accident. But he felt so hurt when his parents got a list of his marks. It also showed the marks to all the other students in his class. His experience seemed to have got many students’ support. But Guo’s team didn’t give up. “ Don’t you fet the time when we all worked harder after knowing the average mark of Class 2?” asked Guo. “We’d have never been so good if we didn’t know how far we were behind. So it’s good to know others’ marks,” said Guo. These words encouraged Du. He partly agreed with Guo’s team. He thought it was good to show the average mark of each class but not individual (個(gè)人的 ) marks. This is the perfect way to respect their privacy (隱私 ) and make them work hard as well. Such a conclusion won most of the students’ hearts. “ Sometimes we need to promise (折中 ), both in a debate and in our life,” 7C 教育資源網(wǎng)（ 最全的免費(fèi)教育資源網(wǎng)站，按教材詳細(xì)分類 （ 域名釋義： 7c 學(xué)科網(wǎng) ） 批量購買請(qǐng)聯(lián)系 ： 372986183， 78763217 added Du. 60.

Paula and Emily disliked Sundays. That was one of the many things the twins had in mon. They shared the same clothes and tied their hair in the same way. In fact, it was sometimes hard for their teachers and classmates to tell the differences between them. Unlike their classmates, they had to get up early at seven every Sunday to prepare for their lessons. Paula had to attend the art class and Emily had to attend her dancing class. Both of them had learned their own classes for three years. “How I wish I could do something different today!” said the twins with one voice. All at once, a wonderful plan came to Paula and Emily at the same time. After
