     Learners of English, especially self-taught learners may have trouble in understanding speeches by

native speakers. The following ways might help improve their listening ability.

     First of all, do things step by step. It is not good to listen to something beyond your level. Better

choose a suitable course and start with the first book. Go on to the second book only after you are sure

you understand the first one.

     Secondly, stick to one course of study. Don't change books often. Never let your attention be attracted

by another course just because it seems to be more"fashionable".

     Thirdly, listen to the English news program over the radio from time to time. Better go through the news

stories in the Chinese-language newspaper first. That will make it easy for you to understand the English

news on the radio.

      Fourthly, if you have time, listen to some interesting stories in some special English programs, such as

V.O.A. or other listening materials of the same level as that of your textbook.

单项选择题

北方股份有限公司(下称北方公司)为增值税一般纳税人,增值税税率为17%(凡资料中涉及的其他企业,需交纳增值税的,皆为17%的税率)。北方公司发生如下经济业务:
(1) 2010年1月1日,北方公司应收南方公司货款余额为1300万元,已计提坏账准备300万元。2010年2月10日,北方公司与南方公司达成协议,南方公司用一批原材料抵偿上述全部账款。3月1日,南方公司将材料运抵北方公司,2010年3月2日双方解除债权债务关系。该批原材料的公允价值和计税价格均为1000万元,发票上注明的增值税额为170万元。
(2) 北方公司收到的上述材料用于生产A产品。2010年6月30日,假设利用该批原材料所生产的A产品售价总额由1450万元下降到1320万元,但生产成本仍为1400万元,将上述材料加工成产品尚需投入400万元,估计销售费用及相关税金为10万元。若把该批材料对外销售,该批材料的市场价为900万元,估计销售材料的销售费用和税金为6万元。
(3) 2010年8月20日,因北方公司欠东方公司的原材料款600万元不能如期归还,遂与东方公司达成债务重组协议:
①用银行存款归还欠款100万元,②用所持某上市公司股票100万股归还欠款,股票在债务重组日的收盘价为400万元,该股票作为交易性金融资产反映在账中,其账面余额为380万元(成本为350万元,公允价值变动为30万元)。假设在债务重组中没有发生除增值税以外的其他税费。当日办完有关产权转移手续并解除债权债务关系。
(4) 2010年12月31日,因上述债务重组业务从南方公司取得的材料已发出60%用于产品生产,结存40%,已计提的存货跌价准备尚未结转。因A产品停止生产,结存的上述材料不再用于生产产品。若把该批材料对外销售,该批材料的市场价为410万元,估计销售材料的销售费用和税金为3万元。
(5) 2011年3月20日,北方公司将上述剩余的材料与南方公司的一台没备进行资产置换,资产置换日,原材料的公允价值为410万元,增值税为69.7万元,南方公司设备的公允价值为479.7万元。
