新SAT首考解析：新SAT文法比較圖表題

2016年3月5日的新SAT全球首考中，圖表類題目在東海岸麻省和紐約考區(qū)出現(xiàn)了多圖對(duì)比的題目，這個(gè)類型的圖表題目以往官方的材料中并未出現(xiàn)多圖比較的題目，而本次首考真題中，出現(xiàn)通過三個(gè)圖表，比較K62，K69與earth，及Mars之間的距離哪兩個(gè)是相等的。題目形式上和以往的看圖表完成數(shù)據(jù)分析有所不同，需要考生對(duì)于三張圖做出相互對(duì)比來進(jìn)行分析，從而得出相同距離的選項(xiàng)。本次考試的圖表題目不僅數(shù)量變?yōu)槎鄨D對(duì)比，圖表內(nèi)容也是天文學(xué)科的專業(yè)信息，本身解題難度并不大，但是需要考生能具備看懂學(xué)科圖表的能力。

　　但其實(shí)，在圖表題目方面，方法還是有跡可尋的，掌握正確的讀取圖表的方法會(huì)幫助我們快速解決圖表類難題。下面我們具體分析圖表類題目的解題方法。

　　Quantitative Information題目不僅考察對(duì)原文文本的理解，更要求考生對(duì)量化的數(shù)據(jù)信息有較強(qiáng)的讀取能力。關(guān)于數(shù)據(jù)圖表的理解，需要大家注意以下幾點(diǎn)：
　　1. 閱讀題干，清晰理解題干要求;
　　2. 精讀圖表標(biāo)題、批注、介紹等，了解圖表數(shù)據(jù)的內(nèi)容;
　　3. 確認(rèn)橫縱軸分別代表什么數(shù)值，一定要注意數(shù)據(jù)的單位;
　　4. 對(duì)應(yīng)數(shù)據(jù)和圖例，重點(diǎn)關(guān)注圖例代表的信息;
　　5. 匹配題干要求，排除法解題。

　　例如下面這道題：
　　Today, epidemiology is considered a basic science of public health. It is a quantitative discipline built on probability, statistics, and research methods, a method of causal reasoning based on developing and testing hypotheses, and a tool to promote and protect the health of the public. Examples of applied epidemiology include monitoring reports of communicable diseases in the community; and tracking down the cause of a food-borne outbreak. While many epidemiologists work for health departments at the local and state levels, a number are also employed by colleges and universities. (1)In 2012, the median wage for epidemiologists in the United States was around $60,000, though this number was substantially larger for those working in the state government. For those interested in pursuing a career in this field, the prospects also look bright, but employment is projected to grow 10 percent between 2012 and 2022.

 
　　(1)After reviewing the passage and the graph, the writer determines that the statement made in the underlined sentence is not accurate. Which of the following revisions should the writer make to correct the inaccuracy?
　　(A) Replace $60,000” with “$50,000.”
　　(B) Replace “$60,000” with “$100,000.”
　　(C) Replace “state government” with “local government.”
　　(D) Replace “state government” with “private sector.”

　　這道題目出錯(cuò)率很高，錯(cuò)誤原因并不在于數(shù)據(jù)的復(fù)雜性，而是大多數(shù)人沒有仔細(xì)理解坐標(biāo)單位的意義。所以解題時(shí)我們要重點(diǎn)注意圖表的圖例、坐標(biāo)等信息，上面這道題目的橫軸percentile表示的是百分點(diǎn)，即在某一百分?jǐn)?shù)數(shù)值以內(nèi)任意可能的數(shù)值，故在annual income在60,000的時(shí)候，private sector的百分點(diǎn)在25%以下，而Local Government和State Government都在50%~75%之間，明顯大于private sector的比例，所以本題目答案D項(xiàng)也就可以輕易選出。在解上面這道題目的時(shí)候我們需要注意確認(rèn)題干要求，重點(diǎn)在于圖表數(shù)據(jù)的解讀能力，正確讀懂圖表的信息，答案用排除法即可得出結(jié)論。
