习惯用法吧，用get into。get into 有两层含义：1.start to be in bad situation: to begin to experience difficulties, or make somebody experience difficulties.e.g.You'll get into all kinds of trouble if you do that. 2.get involved or interested in something: to become involved or absorbed in something.e.g.She's starting to get into programming.Microsoft? Encarta? 2007. ? 1993-2006 Microsoft Corporation. All rights reserved.而词典上查不到fall into，只有“fall in ”和“fall in with ”的用法。
