試題分析:when當(dāng)……時(shí);while當(dāng)……時(shí),一邊……一邊……;as   因?yàn)椋S著;what time什么時(shí)間。句意:當(dāng)我的母親正在做飯時(shí),我正在做作業(yè)。While引導(dǎo)時(shí)間狀語(yǔ)從句強(qiáng)調(diào)主從動(dòng)作的同時(shí)發(fā)生,結(jié)合語(yǔ)境可知選B。
點(diǎn)評(píng):連詞在句子中主要起聯(lián)系上下文的作用,他們之間的區(qū)別就是表示邏輯關(guān)系的不同,所以在解題時(shí)先要理解上下文含義,然后根據(jù)上下文邏輯關(guān)系選擇合適的連詞。連詞的用法都比較多,語(yǔ)義之間還有交叉,熟記其基本應(yīng)用規(guī)則,了解其區(qū)別,注意固定搭配對(duì)象,是做好此類(lèi)題型的關(guān)鍵。
