寒假作业 08 条件状语从句
表示条件或前提的从句叫作条件状语从句。连词 if 的意思是 “如果”，它引导的句子表示某事发
含义 生所需要的条件，即 “在 … … 条件下某事才能发生”，在句子中充当状语，因此我们称之为 if
引导的条件状语从句。
①if + 从句，主句 如 If you take the bus to the party, you'll be late.
结构 ②主句 + if + 从句 如 You'll be late ，if you take the bus to the party.
if 从句既可放在主句前，也可放在主句后。若 if 从句放在主句前，须用逗号隔开。
当主句用一般将来时，if 引导的条件状语从句用 If I get up late
1.主将从现
一般现在时。 tomorrow, I'll be late
for school.
时态
原则
如果主句是含有 must, can, may, might, should, If you have the flu,
2.主情从现
could, would 等情态动词时，从句用一般现在时。 you should see a
doctor.
Let me know if you
3.主祈从现 如果主句是祈使句，那么从句通常也是一般现在时。
need my help.
1.将两个句子合并为条件状语从句。如 It will rain tomorrow. I will stay at home. → If it
rains tomorrow, I will stay at home.
2. if not 意为 “如果不” ，可以与 unless “除非” 进行句型转换。即 if not=unless. 如 If you
don't get up early, you will be late for school. = You will be late for school unless you get up early.
句型
3.借助 “祈使句 + and/or + 句子 (一般将来时)” 这一句型来转换。其中，在句意上 and 表示顺
转换
承； or 表示转折，意为 “否则” 。如 If you study hard, you'll pass the exam easily.= Study
hard and you'll pass the exam easily. = Study hard ，or you won't pass the exam easily.
4.借助 without 或 with 来转换条件状语从句。如 If you help me, I'll finish the work soon.
= With your help, I'll finish the work soon. If you don't help me, I won't finish the work.= Without
your help, I won't finish the work.

学科网（北京）股份有限公司【易错提醒】
（1）在if引导的条件状语从句中，当主句是一般将来时态时，一般不使用be going to结构，而要用
will。
I’ll help you with your English if I am free tomorrow. 如果明天我有空，我会帮你学英语。
（2）在if引导的条件状语从句中不能够使用some，而要用any。
If you have any questions to ask, please come to my office. 如果你有问题要问的话，请到我办公室来。
（3）为避免重复，条件状语从句常用助动词 do (does/did) 来替代上文所提到的动作。如 I think I'll
take the bus to the party. If you do, you'll be late.
（4）如果 if 翻译为 “是否”，则引导的是宾语从句，而不是条件状语从句。如 I want to know if
he will finish the work on time.

二、阅读理解
A
Some people think only school children do not agree with their parents, however, it is not true.
Communication is a problem for parents and children of all ages. If it’s hard for you to communicate with
your parents, don’t worry about it. Here is some advice for you to bridge the generation gap (消除代沟).
4 / 7
学科网（北京）股份有限公司Don’t argue (争辩) with your parents. Don’t go to your parents when you are angry. Your parents probably
won’t consider your ideas if you are shouting at them. And you can’t express yourself well if you are angry. Go
someplace to cool off. Make sure you understand why you are unhappy. Then think about what you want to say to
your parents. If you don’t think you can speak to them at the moment, try writing a letter.
Try to reach a compromise (和解). Perhaps you and your parents disagree on something. You can keep your
disagreement and try your best to accept each other. Michael’s mother didn’t agree with him about buying a
motorcycle. They argued over it. But they finally came to a compromise. Michael bought the motorcycle, but only
drove it on certain days.
Of course, your parents might refuse to compromise on something. In these situations, it is especially
important to show love and respect (尊敬) to them. Showing respect will keep your relationship strong.
Talk about your values. The values of your parents are probably different from those of your own. Tell your
parents what you care about, and why. Understanding your values might help them see your purposes in life.
A good relationship with your parents can make you a better and happier person. It is worth having a try!
16．The passage tells us ________ have a communication problem.
A．parents and other people B．school kids and their parents
C．teachers and their students D．parents and children of all ages
17．Your parents probably won’t consider your ideas if you ________.
A．don’t talk to them often B．write a letter to them
C．don’t speak to them politely D．express yourself well
18．The underlined phrase “cool off” in the passage means “________”.
A．to make yourself happy B．to get you quiet and relaxed
C．to have a good rest D．to hide yourself quickly
19．If there’s really a generation gap between you and your parents, you’d better ________.
A．have a talk with them often B．keep away from them
C．agree with them all the time D．know about their values

三、短文填空
阅读下面短文，在空白处按要求填入适当的单词或括号内单词的正确形式。每空1词。
Many teenagers don’t get along well with their parents and they don’t know what to do. If you face such a
problem, what I’m saying now might be 25 (help) to you.
Have you ever 26 (think) of talking to your parents to find out why you don’t get along well with
each other? When I was a teenager, I didn’t get on well 27 (介词) my parents either. We sometimes
argued with each other. I am sorry that I had such 28 (冠词) experience. Now I’m a mother of four girls.
Of course, we have different 29 (opinion), but I encourage 30 (they) to communicate with me
openly and honestly. So far, they have trusted me and 31 (come) to me for anything. As a result, we get
along very well.
Arguing with your parents will 32 (true) make them angry and you won’t feel good. Also,
remember that the most important thing is to solve problems and silence will only make the situation worse. Try
your best to be calm.

example, you may want to be an artist in the future, 33 (连词) your parents want you to do something
else. If so, try to think in their shoes.
Life is too short and the family is important. 34 (try) your best to get along well with your

阅读下面短文，简略回答问题。
It’s common for parents to compare their children with other kids. While they might mean well, it can make
you feel sad or even angry. So, how should you deal with this situation?
Understand their purposes.
Most parents compare because they want you to improve. They believe that others’ success will encourage
you. So, try to understand their purposes. Ask yourself: are they really criticizing (批评) me, or just hoping I’ll do
better?
6 / 7
学科网（北京）股份有限公司Communicate calmly.
If comparisons get you down, talk to your parents in a respectful way. For example, you can say, “I know
you want me to succeed, but when you compare me with others, I feel like I’m not good enough.” This helps them
understand your feelings without starting an argument.
Turn comparisons into motivation (激励).
If your parents praise (称赞) some people, ask yourself what you can learn from them. Maybe they study
efficiently, practise more, or use time more wisely. Get into their good habits, and you will do better next time.
Build self-confidence.
Write down your strengths—maybe you’re creative, kind, or brave. When your parents compare, think of
what makes you special. With the confidence, you will not care too much about unhelpful comparisons.
Parents’ comparisons can be hard, but you can deal with them wisely. Remember, you are not defined (定义)
by others’ success-your progress is what truly matters.
1．Why do most parents compare their children with others?
2．What should you do if comparisons get you down?
3．Why does the writer advise learning from the people your parents praise?
4．How can you build your self-confidence when facing comparisons?
5．In your opinion, what else can we do to deal with parents’ comparisons in a good way? （答案须与文中提到
的方式不同）
