问题补充：
Marcia isn’t going to the party tomorrow. I’m not going there, .
A. too
B. also
C. both
D. either
答案：
A. too
B. also
C. both
(答案→)D. either
解析：根据语境可知此题重点考查too，also和either的区别。too和also一般都用于肯定句，too放在句尾，通常用句号隔开，also放在实义动词前，联系动词后。例：He runs fast,too.=He also runs fast. Im a student,too.=Im also a student. either主要用于否定句，放在句尾，通常用逗号隔开。例：I don know it,either. 注意：另外too与to连用还有“太..以至于不能.. ”的用法。例：Hes too old to go. The lesson is too difficult to understand.
