确。7.参考答案：A解析：本题考查英语引用规范。在直接引用时，确实需要包括页码。因此，该说法正确。8.参考答案：B解析：本题考查英语词汇辨析。虽然“there,”“their,”和“they're”是同音异义词，但它们在句子中的用法和意义不同，不能随意替换。因此，该说法错误。9.参考答案：A解析：本题考查英语语气。虚拟语气用于表达假设或与事实相反的情况。因此，该说法正确。10.参考答案：A解析：本题考查英语词汇辨析。“compliment”意为赞美或奉承，而“complement”意为补充或使完整。因此，该说法正确。四、简答题1.参考答案：B解析：本题考查英语语法中现在简单时和现在进行时的区别。现在简单时通常用于描述习惯性动作或一般事实，而现在进行时则用于描述正在进行的动作或现阶段正在发生的临时性动作。选项A错误，因为两者虽然都可用于描述现在发生的动作，但用法不同；选项B正确，准确描述了两者的主要区别；选项C错误，现在简单时不一定使用be动词；选项D错误，现在简单时用于描述将来计划的情况较少。2.参考答案：B解析：本题考查正式商务邮件的写作规范。选项A正确，发件人地址应放在邮件顶部；选项B正确，主题行应清晰简洁；选项C错误，正式邮件应使用正式语气；选项D错误，收件人地址应放在邮件顶部。因此，B是正确答案。3.参考答案：B解析：本题考查英语中however的用法。选项A错误，however可以放在句首，但通常需要逗号与句子隔开；选项B正确，however用于引出与前面内容相反的信息；选项C错误，however在句中时不需要逗号；选项D错误，however表示转折，而therefore表示因果。因此，B是正确答案。4.参考答案：A解析：本题考查引用文献的规范。选项A正确，引用直接内容时应使用引号；选项B错误，引用时可以paraphrase，但直接引用也是允许的；选项C错误，即使是常识也需要注明来源；选项D错误，长文本可以引用，也可以paraphrase。因此，A是正确答案。5.参考答案：B解析：本题考查过去完成时的常见错误。选项A错误，过去完成时与简单过去时的确容易混淆；选项B错误，这是过去完成时的正确用法；选项C错误，这是过去完成时的正确用法；选项D错误，这是现在完成时的用法。因此，B是正确答案。6.参考答案：B解析：本题考查商务谈判中表达不同意见的技巧。选项A错误，攻击性语言不利于谈判；选项B正确，礼貌地表达不同意见是谈判中的关键；选项C错误，忽视不同意见可能导致问题；选项D错误，即使不确定也要表达意见。因此，B是正确答案。7.参考答案：A解析：本题考查正式信封的地址书写顺序。选项A正确，收件人姓名、地址、发件人地址的顺序是正确的；选项B错误，发件人地址应在最下方；选项C错误，收件人姓名应在最上方；选项D错误，收件人姓名应在最上方。因此，A是正确答案。8.参考答案：C解析：本题考查英语中表示对比的常用短语。选项A错误，表示“此外”；选项B错误，表示“作为结果”；选项C正确，表示“另一方面”，用于对比；选项D错误，表示“为了目的”。因此，C是
