take charge (of)… 照顾……，接管，开始管理

倒装句，倒装句的结构为“副词+助动词(be，do，have，can，must等)+主语+句子的其余部分”。

用倒装句的情况：
①句首为否定或近似否定的副词(never，rarely，little，on no occasion，hardly，no sooner…that 等)：
Never has he got so many letters.
On no occasion must you accept any money if he offers it.
②句首为only构成的词组(如only after，only then等)：Only then did I realize what a mistake I have made.如果only 加上状语放在句首，那么就要用倒装语序。

即把肯定句语序变成一般疑问句语序。

It is only in recent years that it gained bad reputation. 强调句型Only in recent years did the tree gain bad reputation. 倒装句也表示强调
be used to doing sth. 习惯于做某事
