英語六級-攻克閱讀關(guān)鍵句140.自從12月的報(bào)告公布以來...

140. Since December, when the report came out, the mayor, neighborhood activists (活躍分子) and various parent-teacher associations have engaged in a fierce battle over its validity: over the guilt of the steel-casting factory on the western edge of town, over union jobs versus children's health and over what, if anything, ought to be done.

譯文　

自從12月的報(bào)告公布以來，市長、社區(qū)活躍分子和各種家長教師聯(lián)合會都參與到一場關(guān)于這份報(bào)告真實(shí)性的激辯中來，內(nèi)容包括：城鎮(zhèn)西邊的鑄鋼廠的罪狀、工會工作與兒童健康，以及，如果有什么的話，一些應(yīng)該做的事。

本句的主干是...the mayor, ...activists and...associations have engaged in a...battle...。when引導(dǎo)的時(shí)間狀語從句對since December進(jìn)行進(jìn)一步說明；冒號后over引導(dǎo)三個(gè)并列的介詞短語對battle over its validity進(jìn)行詳細(xì)說明。if anything為插入語，意為“如果有什么的話”。
engage in意為“參加，從事”。如：
I have no time to engage in the shopping. 我沒時(shí)間購物。
validity意為“真實(shí)性，確實(shí)性”。如：
The public question the validity of these figures. 公眾對這些數(shù)據(jù)的真實(shí)性表示懷疑。
versus意為“對陣；相對”。如：
The final game tomorrow is Brazil versus France. 明天的決賽是巴西隊(duì)對法國隊(duì)。
