Am I saying everything I need to say? 我正在说的都是我需要说的吗?
everything I’m saying necessary中everything主语, I’m saying做everything的定语,is系动词,necessary做表语,对不?
----Bingo!是对的
more than one person at once中more than one person翻译不止一个人,对不? at once什么意思?
------------一次不止一个人,这里at once就是at one time
补充：
Is there a clear objective and purpose to what I am saying? 是什么结构?objective 和purpose区别?what I am saying修饰谁?为什么purpose后用to?
转换成陈述句语序是：there is a clear objective and purpose to what I am saying.
所以后面的what从句是做为to后面的名词性从句,没有修饰作用,是句子的成分.
objective 和purpose我觉得在这里是双重使用,表达更准确的意思吧
是objective 和purpose后用to,习惯搭配吧
