GRE填空中同義詞的作用
導語：同義詞是指意義相同的一組詞語，可以分為等義詞和近義詞兩種。近義詞是指意思相近，但不完全相同；而等義詞的意思完全相同。
ETS所尋求的變化，在反義重複方面變化空間並不大，無非是把詞彙變得難一些，因為對立二分的概念還是很容易分辨的。在同義重複方面，ETS的變化空間就要大得多，因為同樣一個意思可以用很多的方式來表達。這就需要我們具有更強一些的語言功底和主動尋找的意識。
舉例說明：找出兩對同義詞。
37.5. Although some consider forcefulness and persistence to be two traits desirable to the same degree, I think that making a violent effort is much less useful than maintaining a steady one.
58.3. Joe spoke of superfluous and vital matters with exactly the same degree of intensity, as though for him serious mattered neither more nor less than did trivialities.
9.2. A perennial goal in zoology is to infer function from structure, relating the behavior of am organism to its physical form and cellular organization.
11.7. When theories formerly considered to be disinterested in their scientific objectivity are found instead to reflect a consistent observational and evaluative bias, then the presumed neutrality of science gives way to the recognition that categories of knowledge are human construction.
值得說明的是，尋找同義重複的意識和能力不僅對於GRE填空重要，對於GRE閱讀理解同樣重要。
閱讀段落，找同義詞反義詞。(摘自黃皮書閱讀理解教程(中國環境科學出版社)E36,P160)
The most vivid expression of such errors occurs in genetically identical( isogenic ) organisms. Even when reared under the same conditions, isogenic organisms are rarely exact copies of one another, and their differences have revealed much about the random variations that result from an organism’s limited supply of genetic information. In isogenic Daphniae, for example, even though the position, size, and branching pattern of each optic neuron are remarkably constant, there is some variability in connectivity, and the number of synapses varies greatly. This variability is probably the result of random scatter beyond the resolution of genetic control and is best termed imprecision, since its converse, the degree of clustering about a mean, is conventionally, called precision.
在該段中, 同樣的`意思用了很多種表達方法：identical; same; exact copies; constant; precision
不同的意思也用了很多種表達方法：errors; difference; random variations; variability; varies; random scatter; imprecison
