(最后一句的主句为祈使句。) 参考答案与解析 一 规则填空 1. 如果。说明主句动作发生的条件。 2. 一般现在。不能在条件从句里机械使用will。 3. 第三人称单数。例如if he comes。 4. 后。前置时通常用逗号与主句隔开。 5. 情态。If you need help, you can call me。 6. 祈使。条件句主句并非必须带will。 二 基础填空 1. rains。将来条件用一般现在时。 2. will understand。结果主句按提示用will。 3. has。she后用has。 4. isn't。否定条件从句用isn't。 5. come。they后用动词原形表示一般现在时。 6. take。祈使句以动词原形开头。 7. don't tell。从句现在时否定为don't tell。 8. asks。Anna为第三人称单数。 9. leave。can后用原形。 10. work。we后用work,条件句不用will work。 三 单项选择 1. A(comes)。条件从句用一般现在时。 2. C(will have)。题目指定主句一般将来时。 3. B(don't understand)。主句祈使,条件从句用现在时。 4. A(is)。条件从句主语she对应is。 5. D(feel)。条件从句一般现在时。 6. D(If)。前半句说明条件。 7. C(will be)。主句表示可能的将来结果。 8. C(If he calls, tell me.)。he后calls,主句祈使。 9. B(will trust)。will后接原形trust。 10. A(have)。并列主语用have,条件从句现在时。 11. B(disagree)。主句否定祈使,条件从句用原形与you搭配。 12. D(出去的条件是不下雨)。区分条件与已经发生的事实。 四 句型转换与完成句子 1. If it rains, we will stay at home. 从句现在时,主句将来时。 2. If you have a question, ask the teacher. 祈使句不用will。 3. She will come if she is free. 语序调整不改变时态。 4. You will miss the bus if you don't hurry. 后置条件从句。 5. If he says sorry, I will forgive him. he后say加-s,主句用will。 6. If a classmate needs help, listen to him carefully. needs体现主谓一致,listen为祈使动词。 五 语篇填空 1. arrives 2. will start 3. has 4. don't understand 5. will find 6. tell 条件从句用一般现在时;everyone、someone按单数处理;结果主句用will;第6空为祈使句,使用原形tell。 语篇还原 Our class is planning a discussion. If everyone arrives on time, we will start at four. If someone has a different idea, we will listen. If you don't understand, ask a question. We will find a good plan if we work together. If you agree with a classmate, tell him or her. 第 1 页 共 1 页 学科网(北京)股份有限公司 $
