gre閱讀技巧 從主題句能了解到的內(nèi)容.

　　gre閱讀技巧是做好閱讀的一種方式，學生平時在練習閱讀題的時候更應(yīng)該注重這些技巧的培養(yǎng)和應(yīng)用。比如，gre閱讀并不需要全文通讀，其實只要讀懂全文的第一句話你就能了解很多信息。下面針對gre閱讀這個技巧舉個例子。

　　Over the years, biologists have suggested two main pathways by which sexual selection may have shaped the evolution of male birdsong.

　　這是本文的主題句，告訴我們一下的信息：

　　1. 本文探討的是一個現(xiàn)象，是關(guān)于鳥的歌曲的性選擇問題。

　　2. 本文是一個新老觀點對比型的文章，關(guān)鍵詞在第一段中間或者第二段開頭

　　3. 本文談到了進化論，那么在文章后面很可能會否定這個說法，并且可能會進行批駁。

　　4. 下文會以性內(nèi)和性間選擇分別展開進行論述。

　　In the first, male competition (這個就是講性內(nèi)選擇了)and intrasexual selection produce relatively short, simple songs used mainly in territorial behavior. In the second, (不看也知道，這是講性間選擇)female choice and intersexual selection produce longer, more complicated songs used mainly in mate attraction; like such visual ornamentation as the peacock&aposs tail, elaborate vocal characteristics increase the male&aposs chances of being chosen as a mate, and he thus enjoys more reproductive success than his less ostentatious rivals. (以上到這里結(jié)束，做題時需要重點看的就是黑體字標示的字，通常來說，文章里面的極端語言需要記住它們的位置，比如最高級，比較級，表示唯一，單獨的意思的詞，可能出直接事實題)

　　The two pathways are not mutually exclusive, and we can expect to find examples that rlect their interaction. (否定詞也要記住位置，可能出改善題)Teasing them apart has been an important challenge to evolutionary biologists.(開始要調(diào)戲進化論生物學家)

　　Early research confirmed the role of intrasexual selection. In a variety of experiments in the field, males responded aggressively to recorded songs by exhibiting territorial behavior near the speakers. (以上是性內(nèi)選擇 )The breakthrough for research into intersexual selection came in the development of a new technique for investigating female response in the laboratory. (這里告訴我們出現(xiàn)了新的突破，這是GRE所特別喜歡的東西，很可能就是本文的重點下面就是要進行說明和舉例)

　　When female cowbirds raised in isolation in sound-proof chambers were exposed to recordings of male song, they responded by exhibiting mating behavior. (對于跟在論點之后的論述或者例子，我們沒有必要去記住太多內(nèi)容，你只要記住這是什么觀點的例子，以及這個例子的關(guān)鍵詞)

　　By quantifying the responses, researchers were able to determine what particular features of the song were most important. In further experim.

　　其實，gre閱讀技巧很簡單，只要抓住出題者出題的習慣和規(guī)律，就很容易找到突破口，發(fā)現(xiàn)做題時的技巧，這樣不僅速度提升了，準確率也提高了。
