the market．But one of his fields was too dry to grow rice or vegetables．Every year it lay empty and the farmer worried about how he could improve this part of his farm. “perhaps I can move the river and make this land grow crops, ”he thought．So he tried．He dug a ditch from the river so that the clear, clean water would reach his dry land．The river changed its course and the dry land became wetter, but the rest of the fields did not get enough water and the crops began to turn yellow and die．“Oh dear, ”thought the farmer, “that is not the answer．”So he moved the river back to its old course．‎ ‎“perhaps I can dig a well, ”he thought, “and that will make the land grow crops．”So he dug a deep well．The water that came up from the well was clear and clean and made the dry land wet and ready to grow crops．But the farmer's neighbours came running to see him, “You are taking our water．It has disappeared from our wells since you dug yours．”They said, “If you continue to do that we shall have no crops for ourselves．” “Oh dear,” thought the farmer, “that is not the answer．”So he stopped getting water from the well．‎ Then he noticed a beautiful bird．“Why not grow trees here?”it said,“There is a lot of water deep under the ground for trees to grow．We birds will be happy to rest in the trees．You can have a crop of coconuts or lychees．Everybody will be happy．” So the farmer did as the bird suggested．Every year the trees grew taller and the fruit grew larger and more plentiful．The farmer grew rich and every year there were more beautiful birds to be seen on his farm．He became ‎ famous and people came from near and far to see his trees and the beautiful birds．Everybody was indeed happy! ‎ Go through each exercise before playing the tape．‎ Pre-teach the new words: ‎ ditch （long roadway dug into the ground to carry water）, course （the way the river makes its way to the sea）and plentiful （more and more of them）．‎ Let the students listen twice and do the exercises on

Maybe there is going to be a war over there. 船正在把许多士兵运往那个国家，或许那儿将有一场战争。‎ STEP3:［典例解析］【全员探究】--教师点拨 ‎1. With more forests being destroyed, huge quantities of good earth _____ each year.（2005山东卷）‎ ‎ A. is washing away B. is being washed away ‎ C. are washing away D. are being washed away ‎[解析] 本句意为：更多的森林正在被毁掉，因此每年有大量的好土正在被冲走。wash away与earth之间的是被动关系，应用现在进行时态的被动语态，huge quantities of good earth为复数概念，所以B不对。答案为D。‎ ‎2. A new cinema ______ here. They hope to finish it next month.（2001年北京、内蒙、安徽卷）‎ A. will be built B. is built C. has been built D. is being built ‎[解析] 根据 “They hope to finish it next month” 判断，新电影院尚未竣工，应该正在建设之中，故使用现在进行时的被动语态。答案为D。‎ ‎3. ---By the way, have you moved into the new house?‎ ‎ ---Not yet. The walls ______. (2005泰安市月考试题)‎ ‎ A. were painted B. are painted ‎ C. are being painted D. are painting ‎[解析] 之所以还没搬进去是因为墙壁正在粉刷，所以考虑用进行时态，也就是 C 和 D 两项。又要用被动形式。所以只能是 C 项。‎ STEP4:Summary and do the same step exercises of USING STRUCTURES (P64 EX1)‎ STEP5: Homework Review grammar.‎ 全 品中考网
