This is not a diet. It’s a simple way to lose weight. And you don’t even have to give up the food you love or join a gym. You just follow some habits that thin people have. Keep them, and you’ll become thin.
(1) Wake-up
When you wake up in the morning, sit up slowly without using your hands. With legs straight out, bend forward until you feel sore in your back. It will burn about 10 calories.
(2) Start with soup
When you have a meal, order a clear soup, and have it before having the main food. In this way, you’ll feel fuller, so you’ll eat less when the main food comes.
(3) An apple ( or more) a day
Apples are full of fiber and water, so your stomach will want less. The study shows that people who eat at least three apples a day lose weight.
(4) Stand up and walk around
Every time you use the mobile phone, stand up and walk around. Heavy people sit on average two and a half hours more each day than thin people. This skill is very important as standing up and walking around will burn 50 or more calories.
Use these skills, and you will have a big weight loss.

Which of the following may the author disagree

A．Sitting up slowly without using your hands helps burn calories.

B．Eating apples every day is good for people’s health.

C．You have to join a gym if you want to lose weight.

D．It’ s good to walk around while talking on the mobile phon

某企业目前年销售收入为3200万元，年经营成本为2400万元，财务效益较好。现计划从国外引进一套设备进行改扩建。该设备的离岸价格为163万美元，海上运输及保险费为17万美元，运到中国口岸后需要缴纳的费用包括：(1)关税41.5万元；(2)国内运输费用12.7万元；(3)外贸手续费(费率为3.5%)；(4)增值税及其他附加税费87.5万元。通过扩大生产规模，该企业年销售收入可增加到4500万元，年经营成本提高到3200万元。设备投资假定发生在期初，当年即投产运营。

该企业生产的产品为市场竞争类产品，国民经济评价产出物的影子价格与市场销售价格一致。在经营成本的计算中，包含国家环保部门规定的每年收取200万元的排污费。该企业污染严重，经济及环境保护专家通过分析认为，该企业排放的污染物对国民经济的实际损害应为销售收入的10%以内才合理。经营成本其余部分及国内运输费用和贸易费用的国民经济评价的计算结果与财务评价相同。

市场研究表明，该产品还可以在市场上销售5年，5年后停止生产。5年末进口设备残值为50万元，并可以此价格在国内市场售出。如果决定现在实施此项目，原有生产线一部分设备可以100万元的资产净值在市场售出。设备的国民经济评价影子价格与市场出售价格相同。本企业的财务基准收益率为10%，社会折现率为10%，美元兑人民币官方汇率为1:6.5，影子汇率换算系数为1.08。

用财务净现值法，从财务评价的角度分析此项目是否可行。
