单项选择题

Most plants can make their own food from sunlight, (1) some have discovered that stealing is an easier way to live. Thousands of plant species get by (2) photosynthesizing, and over 400 of these species seem to live by pilfering sugars from an underground (3) of fungi(真菌). But in (4) a handful of these plants has this modus operandi been traced to a relatively obscure fungus. To find out how (5) are (6) , mycologist Martin Bidartondo of the University of California at Berkeley and his team looked in their roots. What they found were (7) of a common type of fungus, so (8) that it is found in nearly 70 percent of all plants. The presence of this common fungus in these plants not only (9) at how they survive, says Bidartondo, but also suggests that many ordinary plants might prosper from a little looting, too.

Plants have (10) relations to get what they need to survive. Normal, (11) plants can make their own carbohydrates through photosynthesis, but they still need minerals.

综合题

(13分)阅读下列材料:

材料一 由于被剥夺了进入美国市场的机会,为了支持其自身工业发展并照顾其自身的失业问题,其他工业国家不得不寻求发掘新的市场。它们还通过各种限制措施,承担起保护其国内市场免受进口冲击的重担。……其直接后果就是以关税、进口配额和国际协定等形式出现的一系列报复性和防御性措施的出台。

——富兰克林·罗斯福《向前看·在路上》

材料二 关贸总协定只是……一个“临时协定”。但它仍只是一个准国际组织,这就是为什么在乌拉圭回合多边贸易谈判中,人们还在酝酿筹建一个新的真正的多边贸易体系的原由。美国就曾利用最惠国待遇原则的例外,无理地取消过波兰的最惠国待遇;许多缔约国也常利用一般禁止量限制原则的例外,大量采用非关税壁垒的措施,推行贸易保护主义等等。在解决国际贸易纠纷方面,关贸总协定的主要手段是协商,最后只是缔约方的联合行动,至今仍没有具备法律约束性的强制手段。这也是许多重大国际贸易争端无法真正解决的重要原因。

——《关贸总协定知识读本》

材料三   WTO协定第2条规定:“包括在附件1、2、3中的各项协议及附属法律文件(以下简称“多边贸易协议”)是本协定的组成部分,对所有成员方均具约束力。”第15条又规定:“各成员方都要保证使其法律、规章与管理办法均符合本协定附件中规定的义务。”从而奠定了WTO法律制度或规则优于各国国内法的宪法性原则。

——赵维田《世界贸易组织(WTO)》

材料四 “本协议缔约方,认识到在处理其贸易和经济领域的关系时,应当是为了提高生活水平,保证充分就业和大幅度稳步提高实际收入和有效需求,扩大商品和服务的生产和贸易,……进而认识到需要积极努力以确保发展中国家,特别是其中的最不发达国家,在国际贸易增长中享有一个与其经济发展需要相适应的份额;热切希望达成互惠和互利的安排,大量减少关税和其他贸易壁垒,消除国际贸易关系中歧视性待遇……。”

——《世界贸易组织协定》

请回答:

(1)结合材料一和所学知识,指出美国实行怎样的贸易政策?并分析其原因和后果。(3分)  

(2)据材料二、三并结合所学知识,分析世界贸易组织成立的必要性。(4分)
