never say 字面上看是：从不说“不”？是不是？有没有“永不言败”的意思？

1.C
介词to后面的宾语是those,不是选项.
who never say "impossible"是定语从句,修饰those.
who在定语从句中明显充当主语,当然使用主格who,而不能使用宾格whom.
2.A
speak out是固定搭配,意思是“毫无保留地说出”.
两句之间是句号吧,这样前句只能是祈使句,而祈使句是用动词原形开头的.
3.B
选项为thinking about的宾语,即宾语从句.
而宾语从句的结构是：引导词 + 陈述句.
AC都是倒装句序,即助动词did和will都放在主语之前,而不是陈述句.
A改成...I gave...,C改成...we will...,就是陈述句了.
D选项的时态明显不对应,排除.

In my mind,I should do anything in my heart,and never give up.Maybe that is a very good manner in most peoper's opinions.But now,I changed,and I find that's not the best way to do anything.
In our life ,we always may meet failure and success.Not every failure you should continue doing.If you want to be a accoutent ,and you try your best to make it come true,but after two or more times failure ,you must consider it once a more and carefully.Whether it is right ,and is there any other job more suitable for you.So you must learn to how to give up and how to choose.The reality is more important at days.
Never say "no" has not always a good habit .Of course ,I don't refuse it ,I think we should stand on some times and also should give up some times .Maybe it bring a lot of treature to our life.
