[单项选择]In the last 500 years, nothing about people-their clothes, ideas, or languages-haschanged as much as what they eat. The original chocolate drink was made from the seeds of cocoa tree by South American Indians. The Spanish introduced it to the rest of the world during the 1500’s. Although it was very expensive, it quickly became fashionable. In Lon-don, shops where chocolate drinks were served became important meeting places. Some still exist today.
The potato is also from the New World. Around 1600, the Spanish brought it from Peru to Europe, where it soon was widely grown. The potato was the main food at Irish table. Thousands of Irish people starved when the crop failed during the "Potato Famine"(土豆饥荒) of 1845～1846, and thousands more were forced to move to America.

Organic Food:Why?
1 Europe is now the biggest market for organic food in the world,expanding by 25 percent a year over
the past 10 years.So what is the attraction of organic food for some people?The really important thing is
that organic sounds more"natural".Eating organic is a way of defining oneself as natural,good,caring,
different from the junk-food-eating masses.
2 Unlike conventional farming,the organic approach means farming with natural,rather than man-
made , fertilisers and pesticides. Techniques such as crop rotation（轮种）improve soil quality and help
organic farmers compensate for the absence of man-made chemicals.As a method of food production,organic
is,however,inefficient in its use of labour and land;there are severe limits to how much food can be pro-
duced.Also,the environmental benefits of not using artificial fertilisers are tiny compared with the amount of
carbon dioxide emitted（排放）by transporting food.
3 Organic farming is often claimed to be safer than conventional farming. Yet studies into organic
farming worldwide continue to reject this claim.An extensive review by the UK Food Standards Agency found
that there was no statistically significant difference between organic and conventional crops.Even where re-
sults indicated there was evidence of a difference,the reviewers found no sign that these differences would
have any noticeable effect on health.
4 The simplistic claim that organic food is more nutritious than conventional food was always likely to
be misleading. Food is a natural product,and the health value of different foods will vary for a number of rea-
sons,including freshness,the way the food is cooked,the type of soil it is grown in,the amount of sunlight
and rain crops have received,and so'on.Likewise,the flavour of a carrot has less to do with whether it was
fertilised with manure（粪便）or something out of a plastic sack than with the variety of carrot and how long
ago it was dug up.
5 The notion that organic food is safer than"normal"food is also contradicted by the fact that many of
our most common foods are full of natural toxins（毒素）.As one research expert says: "People think that the
more natural something is,the better it is for them.That is simply not the case.In fact,it is the opposite
that is true:the closer a plant is to its natural state,the more likely it is that it will poison you.Naturally,
many plants do not want to be eaten,so we have spent 10,000 years developing agriculture and breeding out
harmful traits from crops."

[单选题]根据下列资料回答问题。按照《广西北部湾经济区2008-2015年人才发展规划》预测，2010年广西北部湾经济区人才需求总量约为115万人，2015年将达到168万人，尤其在石化、林浆纸、能源、钢铁和铝加工、海洋产业、高新技术、物流和现代服务等九大支柱产业都面临着巨大的人才需求。比如，石化产业到2010年需要1. 7-1.8万名专业人才；钢铁和铝加工业需要5.15万人。到2015年，将达到9. 6万人。这种需求可以说是规模空前的，而广西现有人才储备不足。首先是人才总量不够多，整体素质不够高。比如，国有企事业单位专业技术人才中，研究生和本科生占的比例只有1. 43%和18%，低于全国的平均水平(2. 1%和25. 4%)。 公务员队伍中，本科以上学历公务员仅占32.3%。其次是人才结构和分布不够合理。70%的专业技术人才集中在非物质生产部门，第二产业仅占16%。再次是高层次人才缺乏。广西1600家国有企业中， 具有高级职称的专业技术人才只有4542人，领军人才十分缺乏，高技能人才严重不足，外向型人才比较紧缺，人才“瓶颈”问题突出。
广西现有的教育资源严重不足，近年广西北部湾经济区的高职教育有了很大发展，已有高职高专院校29所，在校总数达到了10万人，但学校分布不合理，发展不平衡，80%以上的学校集中在南宁市，其他各市学校数量很少，北海市3所，钦州市1所，防城港市甚至还没有高等职业皖校。2007年广西普通高等教育招生数占全国招生数的2. 61%，低于广西总人口占全国人口的比例3.61%。近年来广西研究生教育发展较快，但相比其他部分地区而言仍显滞后。
根据资料，以下说法不正确的是（ ）。
A.广西研究生教育发展较快，在全国遥遥领先
B.广西人才“瓶颈”问题突出表现在:现有人才储备不足和现有教育资源严重不足
C.在广西的国有企业中，平均每个企业拥有高级职称的人数不到3人
D.虽然广西的髙职教育有了很大发展，但是学校分布不合理，发展不平衡
