2018考研英語(yǔ)：經(jīng)典語(yǔ)法長(zhǎng)難句解析（92）

　　That means a higher proportion of what is in the sea is being caught, so the real difference between present and past is likely to be worse than the one recorded by changes in catch sizes.

　　【分析】

　　這是因果復(fù)合句，前半句是原因，后半句結(jié)果，so是斷句標(biāo)志。前半句中， that means后面是一個(gè)省略that的賓語(yǔ)從句，其中主語(yǔ)是a higher proportion of what is in the sea ，謂語(yǔ)是is being caught 。后半句是一個(gè)比較級(jí)結(jié)構(gòu)the real difference … is likely to be worse than the one…，注意recorded by changes in catch sizes是一個(gè)過去分詞結(jié)構(gòu)，修飾the one。

　　【詞匯】

　　a higher proportion of更高比例的

　　catch sizes捕獲量

　　【譯文】這意味著更高比例的海洋生物正在被捕殺，因此介于現(xiàn)在和過去這一段時(shí)間，真正差別可能比捕獲量所記錄的變化更要糟糕。
