But, unluckily, Lily's grandfahter is ill in bed while Lily's parents are on a business trip and will be back next week. Furthermore, math test is coming, and Lily has to prepare for it these days. So, Lily says sorry to Jim about not going to Jim's birthday party.这是第三人称叙述的,如果你需要的是第一人称叙述,把人的名字改成第一人称就行了.
