In early summer, one of the most popular fruit is strawberry(草莓). It is said strawberry is the "Queen of fruit" as it has many nutritious elements. But many people feel that the strawberry in the current market tastes different as many strawberries are artificially(人工地)grown and some even have a scent of pesticides(杀虫剂).So finding naturally-grown strawberries is a hot issue. There are some places where you can not only find tasteful strawberries, but also enjoy picking them.
Tianxing Strawberry- Picking Garden
As one of the biggest strawberry-growing areas, Tianxing is known for its healthy fruits. The strawberries here are pesticide-free with no artificial coloring. And now the farm has a special offer that you can get a kilogram of strawberries for only 12 yuan. Here, visitors can have fun picking strawberries as well as taste their freshness . And if you are a newcomer, you can get a discount card and enjoy an extra 20 percent discount on your next purchase.

Taolin Strawberry Garden
This garden is not as famous as the first one, but it is a quiet place and relaxing. The strawberries here are much cheaper than those sold in markets. It only costs 6 yuan per kilogram.You can also buy freshly-picked lettuce and Tonghao, a green vegetable. You can have fun picking strawberries in person, but you can’t taste them for free.

Baihe Green Strawberry Garden
Baihe Town is the biggest strawberry-picking area. Known for the freshest and healthiest strawberries, this place is named as the "Hometown of Strawberries". The price for this fruit is about 12 yuan per kilogram. And you can bargain(讲价) with the local sellers for further discounts.

有关人士认为,“人类基因组草图”的测绘成功仅仅预示着一个新的开端,真正的研究工作还只刚刚起步。例如,“草图”中留下了许多空白需要填补,不少可能包含着重要的医学信息的空白又顽固地拒绝“泄露自己的秘密”。除了最先完成的22号染色体长臂中有3%被证明无法解读外,从那时以来完成的4号染色体也留有很多空白。此外,大约有10%的基因组由于其重复性而根本不可能测序。
据国外某些杂志报道,即使到2003年“人类基因组计划”完成了终图,漏洞依然会存在——某些基因将被忽略不计。而蛋白质作为生命三联体的最后一位“成员”,又是迄今为止最难攻克的堡垒。
全人类只有一个共同的基因组,但是由于各种内外因素的作用,世界上每个人都有差别,这种差别被称为单核苷酸多态性。目前,生物学家已利用单个DNA中的变化来跟踪人体基因的变异,并借此评估人类各种生物学现象的奥秘,如健康状况、对疾病的易感性、寿命长短、人类的起源等等。
人类大部分的DNA都是“垃圾”,几乎不起什么作用或至少是没有明显的用途。剩下的则是渊源于植物、动物甚至细菌这一最原始生命形式的基因的“大杂烩”。事实上,大量在维系细胞的基本功能,如修补和解读 DNA方面所需的基因,与促使细菌保持原样的基因没什么两样。
我们在回溯生物进化史的过程中又会发现,人们曾与植物、动物以及软体虫和有翅昆虫共同分享无数的基因。例如一种古怪的被称为“声波刺猬”的基因,它对昆虫在成熟中翅膀生长和发育起着重要的作用。这一相同的基因,在人的胚胎中则起着协调手臂生长和发育的作用。所以,人类基因与某些哺乳动物更为接近也就 [ ]了。例如鼠的基因与人极为相似,它的基因组一致被描述为探明人类基因组的“罗塞塔石碑”(即为解读古埃及象形文字提供线索的石碑)。此外,猩猩的DNA与人只相差1.5%,因而分析这一看似微不足道的差异,自然有助于揭示人之所以为人的奥秘。
看来,不同物种似乎是通过长期复制、改良和组合现存基因而获得进化的。正是这种逐渐从多细胞有机物中汲取新鲜养分的“复制”过程,才使人类不断进化以至于成为超越低级生命形式的高级动物。所以,有专家将基因比作砖块,“用它既能修车库,也可以盖摩天大楼,关键是看你如何运用”。

下列对人类基因工作组研究的表述不正确的一项是( )。

A.“草图”中留下了许多空白需要填补,不少可能包含着重要医学信息的空白依靠目前的科技无法解读

B.生物学家已能利用单个DNA中的变化来控制人体基因的变异,并借以评估人类各种生物学现象的奥秘,如健康状况、对疾病的易感性、寿命的长短、人类的起源等等

C.人类大部分DNA几乎不起作用或者至少是没有明显的用途,剩下的则是渊源于植物、动物甚至细菌这一最原始生命形式的基因,这说明“万物之灵”的人类的起源实际上也是很“卑微”的

D.人类的基因与某些哺乳动物更为接近,分析这一看似微不足道的差异,自然有助于揭示人之所以为人的奥秘

已知下列数据:

实验室制乙酸乙酯的主要装置如上图I所示,主要步骤为:①在30mL的大试管中按体积比1:4:4的比例配制浓硫酸、乙醇和乙酸的混合液;②按照图I连接装置,使产生的蒸气经导管通到15mL试管所盛饱和Na2CO3溶液(加入1滴酚酞试液)上方2mm~3mm处,③小火加热试管中的混合液;④待小试管中收集约4mL产物时停止加热,撤出小试管并用力振荡,然后静置待其分层;⑤分离出纯净的乙酸乙酯。

请同学们回答下列问题:

(1)步骤①中,配制这一比例的混合液的操作是_________________________________。

(2)写出该反应的化学方程式_____________________________,浓H2SO4的作用是___________________________。

(3)步骤③中,用小火加热试管中的混合液,其原因与结论__________________________。

(4)步骤④所观察到的现象是_________,原因是________________________。

(5)步骤⑤中,分离出乙酸乙酯选用的仪器是_________,产物应从_________口倒出,因为__________________。

(6)为提高乙酸乙酯的产率,甲、乙两位同学分别设计了如上图甲、乙的装置(乙同学待反应完毕冷却后再用饱和Na2CO3溶液提取烧瓶中产物)。你认为哪种装置合理,为什么?答:_____________________________。
