A。句意为“Tom 一到家就会给我打电话的”。本题考查时问状语从句。主句为一般将来时，assoon as 引导的是时间状语从句要用一般现在时，故答案为 A 项。2. B。句意为“直到老师到了我们才会开始开会”。本题考查连词的用法。not... until... 意为“直到……才……”。3. D。句意为“如果我们不保护地球，我们将没有水喝”。until 直到……；before 在……之前；though 尽管，虽然；if 如果。四个选项中 D 符合句意。4. B。句意为“Jane，离开教室前请关灯”。after 在……之后；before 在……之前；until 直到；but 但是。根据句意应选 B。5. C。本题是由 while 引导的状语从句，强调的是 “正在看电视时，门铃响了”，所以从句用过去进行时，主句用一般过去时。答案为 C。6. A。前面一句是说明理由“她很忙”，才产生后面的结果“不能参加你的生日晚会。”答案是A。7. C。如果主句用否定形式，从句用肯定形式，表示“直到……才……”，并且主句的谓语动词为非延续行动词（如：leave，start，come，see，go to bed 等），表示这一动作直到某时才开始发生，故选择 C。8. A。在时间、条件状语从句中，用一般现在时表将来意义。9. A。在英语里，有一些非延续性的动词，他们只是一瞬间就结束的动作，如：come，go，arrive，reach，see，hear，close，leave，begin，start，lose，buy，fall，join，die，get up 等，用 It is… since…的句型来表达目前存在的一种状态。故正确答案为 A。10. B。由 while 引导的从句表示某个动作还在进行的同时，另一个动作也在进行之中。故正确答案为 B。11. B。so…that…意为“如此……以至于……”，表示结果，故正确答案为 B。12. B。在 not…until…句式中，意为“直到……才……”，句意为“直到爸爸回来，我才上床睡觉”。13. D。由 since 引导的一般过去时从句，可知主句要用现在完成时。句意为“自从 1989 年我们最后一次相见，就没有再相见过”。14. A。句意为“即使我们失败十次，我们都不会放弃在”。even if 意为“即使”引导让步状语从句。15. B。考查 if 引导的条件状语从句。如果主句用一般将来时，从句用一般现在时表示将来的意义。II.根据汉语提示，完成下列句子。1.
