标题: og 12 RC 128 五个荷尔蒙的那道题 ~~~ [打印本页]

作者: debbiebeansky 时间: 2012-8-9 20:48 标题: og 12 RC 128 五个荷尔蒙的那道题 ~~~

Unlike the oligosaccharins, the ﬁve well-known

(15) plant hormones are pleiotropic rather than specific; that is, each has more than one effect on the growth and development of plants.The ﬁve have so many simultaneous effects thatthey are not very useful in artiﬁcially controlling the growth of

(20) crops

我把需要看的地方摘了出来，然后咱们看这道题哈：

According to the passage, the ﬁve well-known plant hormones are not useful in controlling the growth of crops because

2，each hormone has various effects on plants
3，none of the hormones can function without the others

我知道2对，但我想知道为什么3错~~~

（ps：附上自己的理由：我认为，“The ﬁve have so many simultaneous effects”，的意思就是：这五个h同时作用。那3中的意思不就是说：没有5个中的一个，就不能起作用 ~~这不是和“这五个h同时作用”一个意思吗？）求nn指点一下我这题，膜拜了先~~~~

我补充一下我的想法，大家帮我纠正一下错误哈~~~~

The ﬁve have so many simultaneous effects thatthey are not very useful in artiﬁcially controlling the growth of

crops

我觉得这里有so 。。。that

那么也就是说，后面的效果是由于前面的问题导致的~
那么原因自然就应该“simultaneous effects ”的我以为~
求指点~~~~

阅读大全PASSAGE 24，前几天刚做的，翻了一下，个人觉得你纠结的点在对simultaneous的理解上，它讲的并不是它们对同一个事物向同一个方向联合在一起共同起作用。这个同时作用并没有说非要绑在一起缺一不可的发挥作用，Auxin例子说的正是five的作用的复杂性，对于artificial没有什么研究得价值，与B选项相关；C选项与问题不太相关，从文中并不能推出" function是否without others" 与" five hormones是否useful" 有因果关系,有点儿跑题。你讲的so...that 强调的是so many ... that中的many，而不是simultaneous.

不知道LZ同学有没有看prep07，建议多看看上面答案的解释，然后你再回头来做这道题我相信你就不会如此纠结了。
我不是NN，说了一堆不知道是否讲明白了，正确与否仅供讨论参考吧。

不需要泪奔跪求啊，你这标题党然后还不贴自己“泪奔跪求”的pp，属于dishonest行为！

The ﬁve have so many simultaneous effects that

this is just explaining what is pleotropic - each of the five hormones has many simultaneous effects.
(draw a diagram: each hormone has multiple downstream effects; therefore, if one hormone level is up, the downstream pathways associated with this particular hormone are simultaneously activated.)

I think you mistake "simultaneous" for "interdependent". These two meanings are totally different.
