选项
A、is
B、will
C、has
D、does
答案
D
解析
此题考查从句中的谓语动词形式。分析题句的结构可以得知,题句是一并列句,but后面的分句又是一个主从复合句,it may create…是主句,if引导条件状语从句,要填入的是if从句中的谓语。解答此题的思路是:首先要判断空白要填入的动词类型,即是be动词还是实义动词;第二要区分的是时态问题,是将来时、完成时还是一般式。根据前一并列分句This robot is supposed to save a lot of labor的意思可以推出,if从句要填入的动词应该是save的意思,所以应排除A项is。按语法规则,条件从句中的谓语要用动词的一般式表达将来时的含义,所以只有D项正确。
