A. at once  B. by mistake  C. in general  D. as well 【解析】由because they have the same colour可知是错拿了词典，正确答案是B。b. 句式包：1.George wanted to make the customer happy. 乔治想让顾客开心。句中的make意为“使得”，happy是形容词，作宾语you的补足语，对宾语起补充说明作用，常用的结构为“make＋名词/代词＋形容词”。【备课例句】The bad news makes her sad. 那个坏消息使得她伤心不已。A boy broke the window. It made the headmaster angry. 一个孩子打碎了玻璃。这使得校长很生气。【温馨提示】当宾语是不定式短语或从句时，多用it作形式宾语。I made it a condition that everybody must be on time. 我提出一个条件，人人都要准时。The heavy rain made it impossible for us to go out. 大雨使得我们无法出去。【横向辐射】make的其他相关句式1.“make＋宾语＋n”意为‘使/让某人 / 某物(成为)……”。【例句】We made him captain of our football team. 我们推选他作我们足球队队长。We made him our monitor. 我们选他当班长。2.“make＋宾语＋do sth”意为“使某人做某事”。 在被动语态中，此类结构中省略的动词不定式 to 要还原。【例句】Our teacher makes us feel more confident. 老师使得我们感到更自信了。The boy was made to work twelve hours a day. 这个男孩被迫每天干十二个小时的活。【课堂变式】What do you think        her         ? A. make; sad B. makes; sadlyC. made; sad D. made; sadly【解析】what 作主语时，谓语动词要用第三要称单数形式，可排除A。再根据“make + sb. / sth. + adj.”确定选C。sadly是副词形式。
