问几个英文语法问题
knowledge of physics and physical fitness rather than simple bravery and a sense of adventure这个句子括号部分哪里不对呢?为什么要改成; The job,of an astronaut requires?为什么of前加逗号?这明明不是两个应该紧紧连在一起的成分的嘛?

As the primary elections draw closer,candidates begin spending more time states where they hope to convert undecided voters to 这里为什么错了呢?还有为什么这个句子的动词时态可以不统一啊?一个是begin ,一个是draw
When Dr.Jantos speaks,she does not attempt to impress her 这里到底括号里的哪里错了呢?

答案

正确的句子:
(1) knowledge of physics and physical fitness rather than simple bravery and a sense of adventure.[ "is required" 语法错误]
(2) A good teacher not only conveys information [ knowledge 比较适合] learned but also instills in her students a love for learning.[information/knowledge learned= 老师所学的知识]
(3) As the primary elections draw closer,candidates begin spending more time [in] states where they hope to convert undecided voters into supporters.[ draw,begin 同样是.没有错!改复数
(4)When Dr.Jantos speaks,she does not attempt to impress her .[speak 的名词是 "speech"; 不是"speaking"!
