試題分析:考查連詞辨析。When當(dāng)…時(shí)(謂語(yǔ)動(dòng)詞可以是延續(xù)性也可以是短暫性);while當(dāng)…時(shí)(謂語(yǔ)動(dòng)詞是延續(xù)性動(dòng)詞);as隨著;after在…后;句意:當(dāng)他被一艘輪船發(fā)現(xiàn)的時(shí)候,他正要放棄。本句中的動(dòng)詞spot是一個(gè)短暫性動(dòng)詞,故使用when。
點(diǎn)評(píng):連詞的詞義辨析要放在上下文的語(yǔ)境中進(jìn)行,要注意上下文的語(yǔ)義的串聯(lián)以及邏輯關(guān)系的推理,特別要注意一些連詞和時(shí)間狀語(yǔ)的固定搭配。
