“Salty” Rice Plant Boosts Harvests
British scientists are breeding a new generation of rice plants that will be able to grow in soil containing salt water. Their work may enable abandoned farms to become productive once more.
Tim Flowers and Tony Yeo,from Sussex University's School of Biological Sciences,have spent several years researching how crops,such as rice,could be made to grow in water that has become salty.
The pair have recently begun a three-year programme,funded by the Biotechnology and Biological Sciences Research Council,to establish which genes enable some plants to survive salty conditions. The aim is to breed this capability into crops,starting with rice.
It is estimated that each year more than 10m hectares（公顷）of agricultural land are lost because salt gets into the soil and stunts（妨碍生长）plants. The problem is caused by several factors. In the tropics , mangroves（红树林）that create swamps（沼泽）and traditionally formed barriers to sea water have been cut down .In the Mediterranean,a series of droughts have caused the water table to drop,allowing sea water to seep（渗透）in. In Latin America , irrigation often causes problems when water is evaporated（蒸发）by the heat , leaving salt deposits behind.
Excess salt then enters the plants and prevents them functioning normally.Heavy concentrations of minerals in the plants stop them drawing up the water they need to survive.
To overcome these problems,Flowers and Yeo decided to breed rice plants that take in very little salt and store what they do absorb in cells that do not affect the plants' growth.They have started to breed these characteristics into a new rice crop,but it will take about eight harvests before the resulting seeds are ready to be considered for commercial use.
Once the characteristics for surviving salty soil are known,Flowers and Yeo will try to breed the appropriate genes into all manners of crops and plants.Land that has been abandoned to na- ture will then be able to bloom again,providing much needed food in the poorer countries of the world.

Flowers and Yeo have started a program______.
A: to find ways to prevent water pollution
B: to identify genes that promote growth in salty soil
C: to breed rice plants that taste salty
D: to find ways to remove excessive salt from soil

答案：B

解析：

第二段的第一句话把两位研究人员Tim Flowers和Tony Yeo的关系讲得很清楚，他们来自同一所大学Sussex University的School of Biological Sciences，故是同事。从上下文看他们不可能是学生，更不会是种水稻的；第三段的第一句里用了pair这个词，但pair不一定就是夫妻，从他们的名字看他们不是同一个姓，而且Tim和Tony都是男性的名字。

本题的答案可以在第三段里找到，这段的第一句话说他们开始了一个为期3年的研究项目，目的是“establish which genes enable some plants to survive salty condition”（确认哪些基因使得某些作物能在含盐的条件下生长）。这和选项B是同一个意思。

引起盐分渗入土壤的3个原因都在第四段里谈到了：第一是阻档海水的天然屏障红树林被砍伐（A)；第二是在地中海地区严重的旱灾导致水平面下降，海水渗透（B); 第三是在拉丁美洲，水分被高温蒸发后留下了盐分（D）。

affect这个动词的意思是“影响”，和influence是同义词，在这个上下文里可以替换用。

四个选项的意思分另，1是：肯定的（positive)、否定的（negative)、有怀疑的（suspicious)、冷淡的（indifferent)，从全文看作者时他们的研究无疑是肯定的。

多选题

Consider each of the choices separately and select all that apply.　 Which of these can be inferred from the fact that the French built orangeries for certain tropical plants?

A

Greenhouses may be used to keep plants at a moderate temperature

B

The climate of France is unsuited to growing tropical plants outdoors.

C

Louis ⅩⅣ was a frequent and enthusiastic traveler to Africa and Asia

正确答案： C,A

解析：
有原文可知，法国人修建“orangeries”（温室）是为了保护热带植物，所以A和B选项都是合理的推测，但这没有暗示Louis X IV亲自寻找过异域的水果，C选项排除。

第11题：

单选题

How should we understand the richness of these three civilizations according to the passage?

A

It meant people’s ability to produce commodities.

B

It meant people’s ability to domesticate plants and animals.

C

In population it meant the ability to raise a ruling class.

D

In population it meant the ability to draw other peoples to the area.

正确答案： A

解析：
推断题由题干定位到文章第五段。该段第二句提到，富裕被理解为人们大量生产产品和提供服务的能力——不仅仅是农业，还包括如金属冶炼、陶艺和商业能力，由此可见，A、B两项的表述过于片面，可排除。该段倒数第二句提到，产品的盈余为地区提供财富，吸引人们来到这里，选项D是对此句的曲解，故排除。该段第三句提到，人口上的富裕意味着他们有盈余来为所控制的城市和地区供养统治管理阶层，或许一支军队。由此可知，选项C符合文意，故答案为C项。

正确答案：B

第17题：

A

Why do plants grow in some places and not in others? Why does some land have so much growing on it，while other land has almost no plants growing on it at all?

To grow plants need several things． One is warmth． In very cold places almost nothing grows． Plants also need water． In very dry parts of the earth only a few unusual plants can grow． That's why dry deserts everywhere are almost not covered by trees or grass．

Plants must also have a place in which to f，ut down their roots and grow． They find it diffi-culr to grow on hard land． The town is built on hard land． The plants here have only the soil found between the cracks of the stones Io grow in．

Another thing plants must have before they can grow is food．

Whar will happen if we try to make things grow on the sandy beach? A few plants，such as beach grass，will grow in sand，L ut most plants won-t． Even if the weather is warm enough．and we water the plants each day． Many of them will die because the sand on this beach has al-most no food for plants．

( )21． According to the passage，plants need _________ things to grow well．

A． two

B． three

C． four

D． five

正确答案：C
Ⅲ．21．C【解析】通读全文可知：植物的生长需要4个条件：1．适宜的温度；2．水;3．合适的土壤；4.养分。

Practice 3　　At first, as he adjusted pumps and checked temperatures, Aaron Boucher looked like any technician in the control room of an electrical plant. Then he rushed to the window and scanned the sky, to check his fuel supply.　　Mr. Boucher was battling clouds, timing the operations of his power plant to get the most out of patchy sunshine. It is a skill that may soon be in greater demand, for the world appears to be on the verge of a boom in a little-known but promising type of solar power.　　It is not the kind that features shiny panels bolted to the roofs of houses. This type involves covering acres of desert with mirrors that focus intense sunlight on a fluid, heating it enough to make steam. The steam turns a turbine and generates electricity.　　The technology is not new, but it is suddenly in high demand. As prices rise for fossil fuels and worries grow about their contribution to global warming, solar thermal plants are being viewed as a renewable power source with huge potential.　　After a decade of no activity, two prototype solar thermal plants were recently opened in the United States, with a capacity that could power several big hotels, neon included, on the Las Vegas Strip, about 20 miles north of here. Another 10 power plants are in advanced planning in California, Arizona and Nevada.　　On sunny afternoons, those 10 plants would produce as much electricity as three nuclear reactors, but they can be built in as little as two years, compared with a decade or longer for a nuclear plant. Some of the new plants will feature systems that allow them to store heat and generate electricity for hours after sunset.　　At Nevada Solar One the other day, Mr. Boucher, 30, ran the computerized control room. He was trying to produce as much electricity as possible while saving heat to tide the plant over as clouds cast episodic shadows on the solar array. “I’ve been fighting it all day,” he said.　　Imperceptibly, in the dusty wind of the high desert, 182,000 mirrors moved from east to west, tracking the sun across the sky.

安让·布切尔看上去和电站控制室中其他任何一位技术人员一样,他首先调整了校泵并检查了温度,然后跑到窗户边望了望天空,以确定燃料的供给是否适合。
布切尔先生正和云层较量,调整电站的操作以便从四散的阳光中获得最大的能量。这种技术在不久可能就会倍受青睐,因为世界各地的人们对这种知之甚少但却很有前景的太阳能源正趋之若鹜。
这可不是那种装在屋顶带有闪闪发光镶板的太阳能设备,而是在数以英亩计的沙漠上铺设聚光镜,将阳光聚集到一种液体上,加热使其变成蒸汽,然后蒸汽带动涡轮机从而产生电能。
这不是一种新的技术,但却很受青睐。随着化石燃料价格的上涨及人们对其所对全球变暖带来的影响的担忧,太阳能热电站被认为是一种极具潜力的可再生能源的来源。
在沉寂十年之后,美国最近新建了两座太阳能热电站,另外10个类似的电站正在筹建之中,计划建于加州、亚利桑那州和内华达州。
在阳光明媚的下午,这10座电站所发的电量能达到3个核反应堆所发出的电量,但这些电站只需要2年久可以建成,而一个核电站需要10年甚至更长的时间才能建成。一些新建的电站带有新的系统,可以储存热能,从而保证电站在日落后能继续工作数小时。
这天,在内华达一号太阳能电站,30岁的布切尔先生在计算机控制的控制室中进行操作。他正尽量使电站能多发点,同时他也在存储热能以便当云层遮住聚光镜是能够使电站继续工作。他说:“我一整天都在和云层较量。”
在风沙四起的沙漠,182000面聚光镜悄无声息的随着天空的太阳从东边转向西边。
