　　專家解讀托福閱讀揣摩生詞法二：利用構(gòu)詞法猜測詞義(利用前、后綴及合成詞猜詞義)

　　1、用前、后綴猜測詞義

　　英語中的前綴、后綴構(gòu)詞頗多，且特定的綴往往表示特定的含義，把握住這一點(diǎn)，可起到以不變應(yīng)萬變的效果。

　　1)He had been overworking and fell ill at last.

　　overwork是由前綴over-加動(dòng)詞構(gòu)成，over有“超過、過于”之意，overwork意思是“工作過多，勞累過度”。再如，overburden負(fù)擔(dān)過重，overcharge要價(jià)過高，overdo做得過分。

　　前綴還有：

　　mis-錯(cuò)，誤：misfortune不幸;mislead誤導(dǎo);mismanage處理不當(dāng)

　　mid-中央：midnight半夜;midway半路

　　under-低于：underdone半生不熟的;underestimate低估

　　anti-反對(duì)：antibody抗體;anticyclone反氣旋;antifreeze防凍劑

　　下面劃線單詞為常見后綴派生詞：

　　1)You must stop dreaming and face reality.(-ty為名詞的標(biāo)志)

　　2)The country is trying to popularize education. (-ize為及物動(dòng)詞的標(biāo)志，再如realize， modernize)

　　2、利用合成詞猜測詞義。

　　Family members take turns choosing a special activity for the evening， and everyone partakes in for fun.

　　根據(jù)短語構(gòu)成及上下文意思看，此處partakes in相當(dāng)于takes part in。再如break out-outbreak(名詞爆發(fā))，set out-outset(名詞起始)，come in-income(名詞收入) 。
