Mycorrhizal fungi (mycorrhizal fungi: 菌根真菌) infect more plants than do any other fungi and are necessary for many plants to thrive, but they have escaped widespread investigation until recently for two reasons. First, the symbiotic association is so well-balanced that the roots of host plants show no damage even when densely infected. Second, the fungi cannot as yet (as yet: adv.至今) be cultivated in the absence of a living root. Despite these difficulties, there has been important new work that suggests that this symbiotic association can be harnessed to achieve more economical use of costly superphosphate fertilizer (superphosphate fertilizer: 过磷酸钙肥料) and to permit better exploitation of cheaper, less soluble rock phosphate. Mycorrhizal benefits are not limited to improved phosphate uptake in host plants. In legumes, mycorrhizal inoculation has increased nitrogen fixation beyond levels achieved by adding phosphate fertilizer (phosphate fertilizer: 磷肥(料)) alone. Certain symbiotic associations also increase the host plant’s resistance to harmful root fungi. Whether this resistance results from exclusion of harmful fungi through competition for sites, from metabolic change involving antibiotic production, or from increased vigor is undetermined.
不懂题目：
18.        The level of information in the passage above is suited to the needs of all of the following people EXCEPT:
(A) a researcher whose job is to identify potentially profitable areas for research and product development
(B) a state official whose position requires her to alert farmers about possible innovations in farming
(C) an official of a research foundation who identifies research projects for potential funding
(D) a biologist attempting to keep up with scientific developments in an area outside of his immediate area of specialization
(E) a botanist conducting experiments to determine the relationship between degree of mycorrhizal infection and expected uptake of phosphate
答案是（E）
感觉要有一定的推论啊，可是完全不知道怎么推，也没搜到解析T_T，求助！先谢谢大家！！

又有一道单词意思题，7-3的sectionA，我是做绿皮阅读填空中的exercise15
阅读文章很长，我只把问题涉及到的上下文贴出来
Such discrimination sometimes stopped short of lifetime servitude or inherited status—the two attributes of true slavery—yet in other cases it included both. The Handlins’ argument excludes the real possibility that Black people in the English colonies were never treated as the equals of White people.
This possibility has important ramifications. If from the outset Black people were discriminated against, then legal slavery should be viewed as a reflection and an extension of racial prejudice rather than, as many historians including the Handlins have argued, the cause of prejudice.
Q:The meaning of ramifications is closet to
meaning
consequence
causes
origin
acceleration
后面给出的答案我觉得是错的，就不写出来了
我觉得结合上下文，causes和origin都靠谱
因为后面的话是outset，所以我想选origin
大家觉得呢？

我个人觉得会是consequence吧  因为最后一句已经说了 the cause of prejudice  说明白人殖民歧视黑人的原因是因为他们有偏见。所以这种可能性是个结果或者影响而不是原因和起源吧！前面也说the real possibility that 。。。。这里可能性的内容是白人在殖民地从来没有把黑人和白人同等看待！也许我的推断有问题，望提建议啊！

嘿嘿，首先感谢和我一起讨论！
我理解的逻辑是：H这人认为黑人白人被平等对待是没可能的。而能被平等对待是有 ramifications的。、
加上后面一句话：rather than as H have argued，说明作者是推翻H的态度，所以对应到前文，H说没这种可能，那作者就应该说有这个可能，为什么有这种可能呢？回到原文的话，就应该是而能被平等对待是有原因或者有初始源头的。
所以我觉得最好选D
如果是consequence是结果。那么就变成了，而能被平带对待是有重要结果的。结果就应该是之后发生的事了，可是接下来作者又讲了最开始的事，逻辑有点乱了啊

这篇是非常经典的深海热水口种群内生物数量大增原因探讨的文章
36套ex11
The deep sea typically has a sparse fauna dominated by tiny worms and crustaceans, with an even sparser distribution of larger animals. However, near hydrothermal vents, areas of the ocean where warm water emerges from subterranean sources, live remarkable densities of huge clams, blind crabs, and fish.
Most deep-sea faunas rely for food on particulate matter, ultimately derived from photosynthesis, falling from above. The food supplies necessary to sustain the large vent communities, however, must be many times the ordinary fallout. The first reports describing vent faunas proposed two possible sources of nutrition: bacterial chemosynthesis, production of food by bacteria using energy derived from chemical changes, and advection, the drifting of food materials from surrounding regions. Later, evidence in support of the idea of intense local chemosynthesis was accumulated: hydrogen sulfide was found in vent water; many vent-site bacteria were found to be capable of chemosynthesis; and extremely large concentrations of bacteria were found in samples of vent water thought to be pure. This final observation seemed decisive. If such astonishing concentrations of bacteria were typical of vent outflow, then food within the vent would dwarf any contribution from advection. Hence, the widely quoted conclusion was reached that bacterial chemosynthesis provides the foundation for hydrothermal-vent food chains—an exciting prospect because no other communities on Earth are independent of photosynthesis.
There are, however, certain difficulties with this interpretation. For example, some of the large sedentary organisms associated with vents are also found at ordinary deep-sea temperatures many meters from the nearest hydrothermal sources. This suggests that bacterial chemosynthesis is not a sufficient source of nutrition for these creatures. Another difficulty is that similarly dense populations of large deep-sea animals have been found in the proximity of “smokers”—vents where water emerges at temperatures up to 350℃. No bacteria can survive such heat, and no bacteria were found there. Unless smokers are consistently located near more hospitable warm-water vents, chemosynthesis can account for only a fraction of the vent faunas. It is conceivable, however, that these large, sedentary organisms do in fact feed on bacteria that grow in warm-water vents, rise in the vent water, and then rain in peripheral areas to nourish animals living some distance from the warm-water vents.
Nonetheless advection is a more likely alternative food source. Research has demonstrated that advective flow, which originates near the surface of the ocean where suspended particulate matter accumulates, transports some of that matter and water to the vents. Estimates suggest that for every cubic meter of vent discharge, 350 milligrams of particulate organic material would be advected into the vent area. Thus, for an average-sized vent, advection could provide more than 30 kilograms of potential food per day. In addition, it is likely that small live animals in the advected water might be killed or stunned by thermal and/or chemical shock, thereby contributing to the food supply of vents.
关于这个的主旨题有疑问
18.        The primary purpose of the passage is to
(A) describe a previously unknown natural phenomenon
(B) reconstruct the evolution of a natural phenomenon
(C) establish unequivocally the accuracy of a hypothesis
(D) survey explanations for a natural phenomenon and determine which is best supported by evidence
(E) entertain criticism of the author’s research and provide an effective response
答案选D，不过作者并没有明确说哪个好哪个不好啊？？而且最后一段还说了advection（另一种解释原因）可以是替代呢，我感觉作者的意思是两种原因加一起才是最好的解释啊，所以不存在哪个更好吧？

这里我和你理解不一样 rather than 后面说“而不是H这个人说的那样'  然后后面补充的一句 the cause of prejudice 这个是对H的这个人的观点给出的理由啊，所以我觉得是先讲了这个可能性 然后说这个就是个结果  后面提到之前是在补充解释原因吧！这里结尾说到了原因 那前面肯定就不是原因而是一个结果或者是影响了啊！我觉得这里应该是首尾呼应吧！有点像语文里面的倒序手法吧！
