          A

          試題分析：or或者，否則；so因此；and 和，并且；but但是。句意：現(xiàn)在我必須走了，否則我上火車要遲到了�！Ｄ懵猛居淇�。結(jié)合語境可知選Ａ。
          點(diǎn)評：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，注意固定搭配對象，是做好此類題型的關(guān)鍵。
