难以适应英文

he found that it's difficult for him to adapt to a new environment .

为您解答be not used to sth 看一下容易混淆的:used to表示过去的习惯性动作，过去如此，现在不再这样了。常译作“过去常常”。如：He used toplay basketball when he was young. 他年轻的时候常常打篮球。There used to be an apple tree here. 过去这儿曾经有棵苹果树。 be used to do表示“被用来做某事”。如：Wood is often used to make desks and chairs. 木头常常被用来制作桌椅。 be used to doing /n. 表示“习惯于”某一客观事实或状态，不强调动作，to是介词，后面接名词或动名词。如：He is used to hard work. 他习惯于艰苦的工作。She is not used to eating Chinese food. 她不习惯吃中餐。

Such a life as you describe would not suit me at all.你说的那种生活我也不适应。He doesn' t feel he belongs / has no sense of belonging here, ie He feels an outsider.他不适应这儿的环境（他觉得自己是外人）.Psychologists are dealing with the problem of maladjusted adolescence and "juvenile delinquency".心理学家对付着不适应环境的青少年和“青少年犯罪”的问题。

不适应:Not meet不习惯:Unaccustomed
