my+father+became+a+teacher+in+1978怎样变成否定句

Answer 1

问：my+father+became+a+teacher+in+1978怎样变成否定句

答：否定句为my father didn't become a teacher in 1978.

答：首先我们判断该句的时态是过去时。（判断依据：in 1978,became）

答：第二步，该句中谓语动词为“became（成为）”。那么根据肯定句变否定句的规则，该句的否定句为主语后面加助动词和not

答：根据时态，我们应该在主语my father 后面添加did not (缩写didn't),同时把谓语动词变回原型（became变为become）

答：希望我的回答对你有所帮助～
