1) Check your predictions in - 这里的in是什么意思?

1)一般来说,不需要in,但在特定语境有用in的可能,假设看录像前,按指令,需要你把预测的相关内容检查一下,写在表格里等背景有这样说的可能。
2)the dinosaurs adapted to live in their own environments 的用法可以,多见美国英语,你可以暂且理解为the dinosaurs adapted (themselves) to live in their environments. 我在美国《国家地理杂志》找到了这样一个例句供你参考:They record in chart form characteristics and abilities of four pterosaurs to see how these animals adapted to survive over millions of years. 如果按你认为的,改用adapt to doing 结构也可以。
3)The reason why 一般看作一个可以单独使用的固定用法即可,多见于口语和非正式文体,可能是从定语从句的省略演变而来的。例如:I can't tell you the reason why.
