近日，ETS官網發布了一篇文章，名為托福成績的對比，并發布了一個成績對比的小工具，用戶可以通過輸入托福的分數，在標尺上檢索到與之對應的雅思分數。

　　這份調查的數據樣本基于1153位既參加了托福又參加了雅思考試的考生成績，但是具體情況也存在因人而異，僅可作為參考。意在幫助同學們選擇更適合自己的留學考試。
　　對應的原文部分如下：
　　Overview
　　ETS developed the score comparison tool to help score users make educated admissions decisions by allowing them to compare TOEFL iBT scores to IELTS Band Scores. The data is based on the analysis of 1,153 individuals who took both the TOEFL test and the IELTS academic test.
　　Comparison Tables
　　Based on the research reports that link TOEFL iBT scores to IELTS scores, ETS developed these comparison tables to help you make informed admissions decisions.

　　ETS does not endorse using the tables to calculate cut scores. Institutions wishing to set cut scores should study the two tests and work with test results to set cut scores that are appropriate to meet their specific needs.
