Answer 1

【答案】

【1】 hadn’t sold

【2】 What had done

【3】 When did begin

【4】 Had been

【5】 When reached

【解析】

【1】I had sold the ticket when she came.意思是“她来的时候我已经把票卖了。”根据题意是变成否定句，这个句是过去完成时，变成否定句，要借助助动词had+not+过去分词。故此空填“hadn’t sold”故答案为(1). hadn’t (2).sold。

【2】She had sung a song to us before she danced意思是“她跳舞前曾给我们唱过一首歌”。根据题意划线部分是“had sung a song”可知这里用what提问，根据题意是过去完成时，变成特殊疑问句要借助助动词had，其结构是What+had+主语+动词的过去分词。do的过去分词是done。故答案为(1). What (2). had (3). done。

【3】They began to climb the mountain after they had bought all the food and drinks.意为“他们买了所有的食物和饮料后开始爬山。”根据划线部分是“after they had bought all the food and drinks.”可知，此题是在问“他们什么时候开始爬山”，用when提问；一般过去时态，助动词用did，When did they begin to climb the mountain?意为“他们何时开始爬山？”根据题意，故答案为(1). When (2). did (3). begin。

【4】I had been very hungry by 10:00 a.m.意思是“到上午10点我已经很饿了。”根据题意是变成一般疑问句。本题是过去完成时，变成疑问句，要借助助动词had提前，其结构是Had+主语+动词过去分词+其他？根据题意，故答案为(1). Had (2). been。

【5】By the time he got to the airport, the plane had taken off.意思是“当他到达机场时，飞机已经起飞了。”根据题意是变成同义句，by the time相当when意为“当……时候”；短语get to the airport相当于reach the airport表示“到达机场”，这里用过去式，reach的过去式是reached，根据句意，故答案为(1). When (2). reached。
