异同之处:turn down的主语可以是人,也可以是物。
例1:We get distracted before we can turn down the heating. (2015年12月六级)
我们在暖气关掉之前心烦意乱。
结构分析:We是主语,get是系动词,distracted是系动词,before引导状语从句,we是主语,can turn down是动词词组作谓语,the heating是宾语。
例2:The boss turned down his offer at the meeting.
会议上,老板拒绝了他的建议。
结构分析:The boss是主语(定冠词the作前置定语),turned down是动词词组作谓语,his offer是宾语,at the meeting是地点状语。
短语: take over接管,借用,占领,接替,取代,占上风
异同之处:take over在句中一般不能单独使用,后面要跟名词或者代词作宾语。表示“取代,占上风”,可单独使用,或者与介词from连用。
例1:Miss Smith has asked for a sick leave,and I have to take over her work for a couple of days. (2014年12月四级)
例2:She had to take over his work because he wasill in bed.
