夏天amy

   这是GWDTN１　的阅读里面的话　没太读懂请大家帮我看一下谢哦  
1.  Low levels of straying are crucial, since the process provides a source of novel genes and a mechanism by which a location can be repopulated should the fish there disappear.
2.  D.an environmentally degraded stream could be recolonized by new salmon populations should the stream recover


2   Although no one has quantified changes in the rate of straying as a result of the disturbances caused by humans, there is no reason to suspect that the effect would be qualitatively different than what was seen in the aftermath of the Mount Saint Helens eruption.

下面这段也是GWDTN1 的阅读  第一段没太读懂
请大家帮我看一下
In corporate purchasing, competitive scrutiny is typically limited to suppliers of items that are directly related to end products. With “indirect” purchases (such as computers, advertising, and legal services), which are not directly related to production, corporations often favor “supplier partnerships” (arrangements in which the purchaser forgoes the right to pursue alternative suppliers), which can inappropriately shelter suppliers from rigorous competitive scrutiny that might afford the purchaser economic leverage.There are two independent variables—availability of alternatives and ease of changing suppliers—that companies should use to evaluate the feasibility of subjecting suppliers of indirect purchases to competitive scrutiny. This can create four possible situations.

1 低水平的走失率是至关重要的，因为该过程提供了新基因的来源和一种机制，如果某地是以该种机制被填充的话，那里的鱼就会消失。
2 如果一个环境上降级的河流被重新引入三文鱼，那河流就会恢复。

2 尽管没有人量化走失率的变化，该走失是人类干扰的结果，但也没有理由去怀疑这个效果会与Saint Helens火山喷发的后果有本质不同。

3 在企业采购中，竞争性审查一般限于那些与最终产品直接相关的供应商。伴随那些与生产无直接关系的间接购买（例如电脑，广告和法律服务），企业更乐意供应商合伙制（买方放弃权利去追求其他供应商的一种安排），这样可以在承担买方经济杠杆的严格的竞争性审查中适当庇护供应商。对于使间接购买的供应商受制于竞争性审查的可行性，企业应该用两个独立变量来衡量，一是供应商的可选择性，二是改变供应商的的灵活性。这可以产生四种可能的情形。


多有不当，欢迎指教。

GWD1-Q36，GWD给的答案是B，我觉得存疑，因为partnerships只出现在最后。其实是问关于partnerships，能推论出什么

GWD1-Q37，就是问，对于什么样的商品才能用indirect purchase 描述，定位到原文第二句。

36Q:
Purchasers could get the cheapest price in competitive-bidding situation. >"best results"
Partnerships may be unavoidable in Type4.
So B
D is irrelevant .  We only know "corporations often favor partnership" as to indirect purchases. We do not know whether it is feasible for end products.

我有我的小梦想

Q36~
corporations often favor “supplier partnerships” (arrangements in which the purchaser forgoes the right to pursue alternative suppliers).
Give up the right to pursue alternative suppliers means the purchaser buy more goods and services now.
我觉得是这个意思~
