海洋经济固定资产增加值率

认真阅读下列素材，并根据广播新闻写作要求，完成第38至41小题写作任务。 福建农民王永富家养野兔走上致富路 如今，人们的饮食习惯逐渐向营养、保健、滋补的方向转变，而素有“美容肉”、“保健肉”之称的野兔自然成为人们喜爱的食品之一。在福建省南安县九都镇新东村，村民王永富养殖的2000只野兔颇受市场欢迎，还没出栏就已经被预订一空。 王永富养殖野兔，是从2007年春天从网上看到：养殖野兔是个不错的投资项目。野兔的皮、毛、肉可兼用，经人工驯化的野兔，改变了其胆小、怕惊吓的一般家兔的不良习性， 同时又保持了原有的野味，平均产肉率还增加了一倍。随着野兔供求市场的日趋火爆，其巨大的市场潜力成为众多投资者的新热点。 王永富一开始就看中了野兔的市场需求，两年多来，他克服了资金短缺、购买野兔良种不易等困难。资金短缺，便自力更生，在自家的后院里搭建了简易的养殖栏。并设法从闽南与山东同时购买200只野兔，自己培育良种。第一个半年养殖周期，经精心繁殖与饲养，便销售出野兔1000只，除去成本，获盈利2万多元。目前，王永富饲养的200只母种兔，每只每年可繁殖30只小兔，每只小兔养大出售平均可盈利20元，光这一项就可获利10万多元。 昨天上午，王永富在南安县农业局召开的县农副业生产总结表彰大会上，被评为“县农副业先进生产者”。他在大会上激动地说：“我感谢领导的关心，感谢党的农村政策好!” 王永富告诉记者，他从南北两地引进种兔，主要为了避免野兔近亲繁殖而造成品质下降。再加上南安得天独厚的生态环境，他养的野兔受到市场的欢迎，根本不愁销路问题。王永富还打算与同村的村民合作，扩大养殖规模，走共同富裕道路；同时，在兔舍周围种上花草树木，既美化环境，又让野兔感到生活在自然环境中。

指出上述稿件的优缺点。

When you enter a supermarket, you see shelves full of food. You walk between the shelves. You carry a shopping basket with your food in it.

You probably hear soft, slow music as you walk between the shelves. If you hear fast music, you walk quickly. The supermarket plays slow music. You walk slowly and have more time to buy things.

Maybe you go to the meat department first. There is some meat on sale, and you want to find it. The manager of the supermarket knows where customers enter the meat department. The cheaper meat is at the other end of the meat department, away from where the customers enter. You have to walk by all the expensive meat before you find the cheaper meat. Maybe you will buy some of the expensive meat instead of the meat on sale.

The department selling milk and milk products such as butter and milk powder is called the dairy department. Many customers like milk that has only a little butter fat in it. One store has three different jars of low fat milk. One says “1 percent fat” on the jar. The second says “99 percent fat free”, the third says “Low fat” in big letters and “1%”in small letters. As you can see, all the milk has the same amount of fat. The milk is all the same. However, in this store the three jars of milk cost three different amounts of money. Maybe the customers will buy the milk that costs the most.

Most of the food in supermarkets is very pleasing. It all says “Buy me!” to the customers. The expensive meat says “Buy me” as you walk by. The expensive milk jar says “Buy me! I have less fat.”
