问题补充：

---Sorry. I have to my sick mother at home..

A. pay for

B. look for

C. go for

D. care for

答案：

A. pay for

B. look for

C. go for

(答案→)D. care for

解析：本题考查动词短语含义的区别。本题的含义为明天你能和我一起去购物吗？对不起，我必须得照顾我生病的母亲。care for 表示照顾，照看的意思，与本题的含义相符；而pay for表示支付的含义，look for表示寻找的含义；go for表示适应于某人的含义；后三者与本题的含义不符，故本题选D。
