阅读下列材料,回答问题:

材料一 江浙地区,在很早以前就是我国的粮仓……而到康、雍、乾时期,“本地(指江浙地区)所产米谷,不足供食用……”。以前地广人稀、物产不丰的湖广地区随着农业生产的发展逐步成为粮食供应的重要基地。过去的“苏湖熟,天下足”变成了“湖广熟,天下足”。此时,江浙地区经济作物广泛种植,粮食不能自给。松江种稻之地只占1/3,每年都从外地运进大量粮食,人口稠密、特别是集中了大批非农业人口的工商业城镇,更是家无隔宿之粮,江浙市镇更是如此。

——引自戴逸《简明清史》

材料二 清朝建立之后,顺治、康熙、雍正统治时期,政府明确提出“王政之本在于农桑”。政府采取了一系列政策措施,尤其是在立法方面加强了对农业生产的扶持与鼓励。正因为如此,康熙、雍正、乾隆百余年时间里,实现了农业经济的较快发展,在一定程度上奠定了该时期封建经济的某种繁荣。

——引自福建人民出版社《中国古代史》

材料三 中 * * 党第十七届中央委员会第三次全体会议提出加强土地承包经营权流转管理和服务,建立健全土地承包经营权流转市场,按照依法自愿有偿服务,允许农民以转包、出租、互换、转让、股份合作等形式流转土地承包经营权,发展多种形式的适度规模经营。有条件的地方可以发展专业大户、家庭农场、农民专业合作社等规模经营主体。

——引自《中国农村土地制度改革演讲大纲》

Passage 1 Honorable Ministers,Your Excellencies,Ladies and Gentlemen, It is a great pleasure to welcome you to the first session of the Conference of the Parties to the WHO Framework Convention on Tobacco Control. One hundred and twenty one countries are now contracting parties to the Convention. Of these, 110 are here today, with full powers of participation. You represent nearly three quarters of the world’s population. You represent nations at all levels of income and all stages of development. //In this powerful gathering, we have three of the five top tobacco-leaf exporting countries, and four of the five top cigarette-exporting countries. This group of countries represents 69% of the world’s cigarette consumption. It might seem astonishing that this group is also preparing to put into action the roadmap for countries to control tobacco. But this group has already changed history. // When the process began there was some skepticism over its success. The skeptics were wrong. You are driving change forward. To name some examples: India has introduced comprehensive tobacco advertising bans. Australia, Brazil, Canada, Singapore and Thailand have introduced highly visible graphic warnings on cigarette packets. The European Union is on its way to doing the same. In Ireland, Norway, and now in Spain, smoking has been banned in indoor public places. These, and other similar steps, will result in a major reduction in tobacco deaths. // New York State passed a smoking ban. It termed this act its "pest public health policy ever". Ironically, now it’s said that the only place you can smoke with impunity in New York City is the United Nations Building. Both Ann Veneman and I have said that this is wrong. // Smoking should be banned in all UN premises. Also, cigarette sales should be banned in all United Nations premises. After all, the people who are smoking in the UN building sometimes are the representatives of the same Member States who have signed up to the Framework Convention. But it can be hard to put agreements into practice. We will all face this. // Ladies and gentlemen, when we know that, in an Irish pub, a smoking ban can really work, then we know that anything is possible. Smoking is an advance contract. Those who smoke don’t pay now, but will do so 30 to 40 years later, when their health fails. They pay with lung cancer, with obstructive airways disorders, with cardiovascular diseases. One in two smokers pays with their life. We have to help them stop smoking. We have to prevent them from starting. // This convention is something that we all committed to. Its provisions are bold. They are based on knowledge of what is effective. We will make it work. Thank you. // (Speech by LEE Jong-wook, former Director-general of WHO, at the Conference of the Parties in Geneva on February 6, 2006)
