答案: DACBB
1. 【D】not until的倒装句型，not until提到句首时，主句中主谓部分要倒装。
2. 【A】省略结构。Not very是I have not been here very long的省略形式。
3. 【C】would sooner同would rather一样，表示“宁愿做某事”，后面应接动词原形，本题还包括一个并列结构，所以than后也应用动词原形。
4. 【B】独立主格结构。Being的逻辑主语不是Carl而是English；本句的谓语动词是is，English与be是主谓关系，be只能以现在分词的形式出现。
5. 【B】get round to 后加名词或动名词，表示“（处理完其他事以后）花时间和精力去做某事”
