【考例分析】
【例1】 He was very tired from doing this for a whole day, ______ he felt very happy since the crop did “grow” higher.
【解析】but
句中very happy与very tired是转折关系,两句间是逗号且没有连词,故填连词but。
【例2】So Nick called to his son, “Go to the village and buy some salt, but pay a fair price for it: neither too much ______ too little.”
【解析】nor
并列连词“neither…nor…”表示“既不…也不…”。
