consider doing还是consider to do ,答案为什么不能选D
Mr.Smith is considering ______ a computer,which is considered ______ a great help in our work and study.
A.to buy; to be B.buying; to be C.to buy; being D.buying; being
答
consider to do sth .所以选A
答
第一个consider doing是表示思考做某事
第二个consider to do 是被当做
所以应该是B哦
答
选B,第一空consider意为“考虑”,后接动名词作宾语；第二空consider意为“认为”,同think of,后可接to be…作补语(并不是宾语),主动式为consider sth.to be…,本句为其被动句sth.be considered to be…,to be有时也可省去.
