too...to do结构中的悬空不定式是optional,即为选择性的,可以用悬空不定式,也可以用普通不定式。例如:The book is too difficult for children to read (it).另外,不定式作目的状语时,悬空不定式也是选择性的。例如:I bought a new suitcase to put my clothes in (it).

大写意味着另一个句子开始,可以你的句子中大写的只是一个that从句,所以是错误的。建议修改如下:Results show that the thermal conductivity ranges from 0.765 to 1.134 W/m/K and decreases with each freeze-thaw cycle.

You should have thanked her before you left.I meant to, but when i was leaving i couldn't find here.这个对话中,meant to是不恰当的。应改为had meant to 或者 meant to have。第二个对话中,would like to have是正确的。
