中,冠詞占用的分值比較小,但頻率比較高,也是不容忽視的一個(gè)考試重點(diǎn),下面我們就通過真題來看一下冠詞的用法。
有關(guān)冠詞的考題在TOEFL測試中所占比例較小,但出現(xiàn)頻率較高,而且是單一題型反復(fù)再現(xiàn),即不定冠詞a和an混淆錯用。這類題目全部集中在Written Expression(16-40題)中。其次,定冠詞the的用法也是考試范圍。
冠詞?碱}型及解題要點(diǎn)
1.不定冠詞a與an的區(qū)別
解題要點(diǎn) “a”后面接以輔音開始的字詞“an”后面接以元音開始的字詞。當(dāng)A、B、C、D四個(gè)選擇答案中出現(xiàn)有a或an,應(yīng)首先察看它后面的單詞,以判斷此不定冠詞是否正確。
