之前新航道GRE小編帶來了GRE小白初入閱讀方面的內容，這次關于涉險入坑GRE?Verbal(語文)難?GRE考試閱讀難?此處需要章老師口頭禪。

  “不慌”。今天，我們繼續“掃盲”：閱讀理解的 主題 和 主要題型 在題面 / 題干上的“花樣”。

  啊哈!又是短篇閱讀，全文篇幅168 words。是不是又是感覺爽歪歪?對的嘛!這個感覺就對了，所以面對GRE的Verbal(語文)部分，也并不是一定一定手足無策的。再趕緊看一下題量，4個questions。壓力不大爽歪歪。

  哇!第一個詞就不認識呢!其實無所謂，認出二個詞fungi是菌類，就可以。迅速判定這個篇章的主題是自然科學主題類別里的生物主題。嗯，不會特別難的。

  Mycorrhizal fungi 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 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 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 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.

  Q1. Which of the following most accurately describes the passage?

  Describe the passage?這種問題什么鬼?主旨題鬼唄。都“描述(整個)篇章”了，但是是考主旨啦，不驚不慌。

  (A) A description of a replicable experiment

  (B) A summary report of new findings

  (C) A recommendation for abandoning a difficult area of research

  (D) A refutation of an earlier hypothesis

  (E) A confirmation of earlier research

  Q2. The level of information in the passage above is suited to the needs of all of the following people EXCEPT:

  又來文字游戲，EXCEPT，無聊了。但是這個題目有點難了，題面 / 題干沒有給提示說明題目的類型。只有通過閱讀選項來發現，這是一道主旨題呢。有點奇怪喲。是的。

  (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

  Q3. It can be inferred from the passage that which of the following has been a factor influencing the extent to which research on mycorrhizal fungi has progressed?

  題面透露了太多，推斷題。畢竟很直接：“It can be inferred”。

  (A) Lack of funding for such research

  (B) Lack of immediate application of such research

  (C) Lack of a method for identifying mycorrhizal fungi

  (D) Difficulties surrounding laboratory production of specimens for study

  (E) Difficulties ensuing from the high cost and scarcity of superphosphate fertilizers

  Q4. The passage suggests which of the following about the increased resistance to harmful root fungi that some plants infected with mycorrhizal fungi seem to exhibit?

  直接信息題(細節題)，而且是一道很簡單的直接信息題。簡直無需多說呀。

  (A) There are at least three hypotheses that might account for the increase.

  (B) An explanation lies in the fact that mycorrhizal fungi increase more rapidly in number than harmful root fungi do.

  (C) The plants that show increased resistance also exhibit improved nitrogen fixation.

  (D) Such increases may be independent of mycorrhizal infection.

  (E) It is unlikely that a satisfactory explanation can be found to account for the increase.
