郑州市九年级英语全册Unit6Whenwasitinvented笔记重点大全

郑州市九年级英语全册Unit6Whenwasitinvented笔记重点大全单选题1、To my surprise, I ________ from hundreds of students to speak to teachers, parents and fellow students. A．was chosenB．would chooseC．chose答案：A句意：让我惊讶的是，我是从数百名学生中挑选出来与老师、父母和同学们交谈的。

考查被动语态。

A. was chosen 曾被挑选；B. would choose 将选择；C. chose 曾选择。

根据译文，I与choose的关系是“我被挑选”，被动关系。

且事件发生在之前，因此本句属于一般过去时态的被动语态。

故选A。

2、Uncle Wang ________the electricity and water in his house before going on holiday.A．took offB．turned onC．shut offD．put on答案：C句意：王叔叔在去度假之前，关掉了电和水。

考查动词短语。

took off脱掉，起飞；turned on打开；shut off关掉；put on穿上。

根据before going on holiday.结合题意可知，此空是“关掉”的意思，其余选项不合题意，故选C。

小提示：“动词+副词”构成的动词短语：这类短语作及物动词时，若宾语为名词，则宾语既可放在短语动词之后，也可放在动词和副词之间。

若短语动词的直接宾语为代词，则位于动词与副词之间。

例如：turn down that man = turn that man down 拒绝了那个男人turn him down 拒绝了他（不能说成turn down him）3、His car ____ five years ago, but it looks quite new.A．buysB．boughtC．is boughtD．was bought答案：D句意：他的车是五年前买的，但看起来很新。
