下面这几个英语句子语法正不正确?
"Let's suppose that the cat is male,the dog female and the bird male."
"Let's suppose the cat to be male,the dog femail and the bird male."
"...,where f(t) is a continuous function,and g(t) a function with lower bound m."
“Let g be the acceleration of gravity,theta the angle subtended by the rod and the vertical axis through the pivot point,and k the coefficient of friction of the joint.”
我的问题是,后面并列的从句部分的谓语能不能像这样省掉?比如说第一、二句中的dog和bird后面省了is,第三句中的 g(t) 后面省了is,第四句中的theta和k后面省了be.
"Let's suppose that the cat is male,the dog female and the bird male."

“Let g be the acceleration of gravity,theta the angle subtended by the rod and the vertical axis through the pivot point,and k the coefficient of friction of the joint.”
并列的从句部分的谓语,因为是同一个词,所以必须像这样省掉
