转基因作物同普通植物的区别只是多了能使它产生额外特性的基因．早在1983年，生物学家就已经知道怎样通过生物工程技术将外来基因移植到某种植物的脱氧核糖核酸中去，以便使它产生靠杂交方式根本无法获得的某种新的特性：抗除莠剂的特性、抗植物病毒的特性、抗某种害虫的特性等．用以移植的基因可来自任何生命体：细菌、病毒、昆虫等．转基因作物目前在世界上已种植有1 000万公顷左右，种植最多的是棉花、玉米和西红柿等．在实验室试种的还有莴笋、西瓜、稻谷等品种．试验的目的除了增产之外，还在于提高这种品种的抗病毒能力．但同时也有专家担心转基因作物可能对环境有危险．比如在美国种植的那种能抗虫害的玉米和棉花，可能加快出现一更难对付的害虫．这类作物的所有分子都分泌出一微量的“杀虫”一种像任何一种一样能选择杀死某害虫的“雾剂”．尤其是那些能抗除莠剂的作物，它们一旦同野生状态下的“表姐妹”杂交之后，那些“表姐妹"也就会因此而成为除莠剂无法除掉的变种了对于这种技术，尽管还有些问题需要继续研究，但这确是人类9000年作物栽培史上一场空前的革命．
对文中所提供的信息，理解不正确的是______．
A．生物学家知道怎样通过转基因技术使作物产生抗除莠剂等特性不过十多年时间
B．转基因作物可能给环境带来危险是转基因研究中不容忽视的问题
C．野生植物同抗除莠剂作物杂交之后的变种已经给农业生产带来新问题
D．转基因是一种新的生物工程技术，它给作物栽培带来从未有过的根本改革

| But 1 a few of them are very 2 . English is one of these. Many, many people use it, not only in England and the U. S. A, but in other parts of the world.

胰液分泌的调节是一个复杂的过程，图一为胰液分泌调节的示意图（部分），图二为咀嚼食物引起胰液分泌的反射弧的结构简图。请据图回答：
英国科学家斯他林与贝利斯作了一个实验：把狗的一段小肠剪下，刮下黏膜，把黏膜与稀盐酸混合加砂子磨碎，制成提取液，将提取液注射到一条狗的静脉中，发现能促进胰腺分泌胰液。由此他们得出了一个结论：在盐酸刺激下，小肠黏膜可能产生了某种物质能促进胰腺分泌胰液。你认为他们的实验能得出这一结论吗？如果你认为能，请说明理由。如果你认为不能，请写出你的实验设计思路。
