由于提高閱讀速度是一個需要長期訓練的過程，為了讓同學們短期提高一些閱讀分數(shù)和學習效果，我們來試試對比一些方法來高效的發(fā)現(xiàn)題目的切入點并且解決問題拿到分數(shù)。
我們來直接看題：
A symbiotic relationship is an interaction between two or more species in which one species lives in or on another species. There are three main types of symbiotic relationships: parasitism, commensalism, and mutualism. The first and the third can be key factors in the structure of a biological community; that is, all the populations of organisms living together and potentially interacting in a particular area.
1. Which of the following statements about commensalism can be inferredfrom paragraph 1?
○It excludes interactions betweenmore than two species.
○It makes it less likely for specieswithin a community to survive.
○Its significance to the organizationof biological communities is small.
○Its role in the structure ofbiological populations is a disruptive one.
解法1：
初學者在看到這樣題目的時候，會先把文章看完甚至翻譯一遍，認為理解了自然就能選對答案。這是正確率最靠譜的做法，但的缺陷是考試時無法在短時間內(nèi)理解文章并且做完題目。所以在閱讀能力不是很強的時候，盡量不要使用看完理解再做題的方法。
解法2：
定位規(guī)律
題干關(guān)鍵詞：commensalism
文中定位點：There are three main types ofsymbiotic relationships: parasitism, commensalism,and mutualism.有三種共生關(guān)系：寄生、共生、互利共棲。說的是題干關(guān)鍵詞本身的內(nèi)容，無法對應選項。
