“我能照顾好一个人”的常见英文表述方式：
1.
I can take good care of one person.
这是最直接的表达，“take good care of”表示“照顾好”。2.
I'm capable of looking after one person well.
“be capable of”意思是“有能力做某事”，“look after”也有“照顾”的意思。3.
I have the ability to care for one person properly.
“have the ability to”表示“有......的能力”，“care for”同样可以表达“照顾”。在具体使用时，可以根据语境和表达需要选择合适的表述。比如在向某人承诺时，可以说：“Don't worry. I can take good care of one person. I'll make sure they are happy and healthy.” （别担心。我能照顾好一个人。我会确保他们开心又健康。）
