一、利用上下文線索猜測(cè)詞義
1、根據(jù)同義、反義關(guān)系猜詞
Today' s teenagers seem to be more liberal in their ideas than their _______grandparents. A. freethinking B. traditional C. old D. happy
traditional與liberal意思相反，故選B.
2、根據(jù)句意或段落文章的上、下文猜測(cè)詞義Klebold and Harris felt _______ and wanted to revenge against those who disliked playing together with them or laughed at them. A. discouraged B. ashamed C. tired D. separated根據(jù)下文的disliked playing together with them判斷此處應(yīng)為“感到孤立”，故選D.
二、利用構(gòu)詞法猜測(cè)詞義(利用前、后綴及合成詞猜詞義)
1、用前、后綴猜測(cè)詞義英語(yǔ)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(wàn)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(guò)、過(guò)于”之意，overwork意思是“工作過(guò)多，勞累過(guò)度”。再如，overburden負(fù)擔(dān)過(guò)重，overcharge要價(jià)過(guò)高，overdo做得過(guò)分。英語(yǔ)中常用的前綴還有：
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(jiàn)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(cè)詞義。
Family members take turns choosing a special activity for the evening， and everyonepartakes in for fun.根據(jù)短語(yǔ)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)
