them".解析：本题考查"there"和"their"的用法区别。这两个词经常混淆，但它们的词性和意义完全不同。"There"是一个副词，表示地点；而"their"是一个形容词性物主代词，表示所属关系。学生需要通过例句理解这两个词的用法，避免在写作中犯错。6.参考答案：Anexampleofapossessivepronounis"mine,"whichmeans"belongingtome".解析：本题考查物主代词的例子。物主代词用于表示所属关系，常见的有"mine,"（我的）、"yours,"（你的）、"his,"（他的）、"hers,"（她的）、"ours,"（我们的）和"theirs,"（他们的）。学生需要掌握这些代词的用法，并在写作中正确使用它们。7.参考答案："Because"isspelledB-A-C-E-S-E.解析：本题考查单词拼写。拼写单词是英语学习的基础技能之一。"Because"是一个常见的连词，表示原因。学生需要通过记忆或使用拼写规则来正确拼写这个单词，避免在写作中拼写错误。8.参考答案：Thepasttenseof"go"is"went".解析：本题考查动
