Ⅱ.阅读理解
Are you the type of person who always says “yes”？I’ve come to learn that it is very important to learn to say “no”．It’s okay.People are still going to like you.They may even respect you more because they know you are honest.
I’m not saying to say “no” to someone who really needs your help.I’m talking about turning down that meeting that you really do not want to attend or that birthday party that you don’t want to be a guest at.
Think for a moment how you feel when you say “yes” to something that you really don’t want to do.If you’re like I once was，you can’t sleep at night and you think about it too much.It weighs on your mind.You try to find ways out.Whatever you’re saying to yourself，if you really wanted to go，you wouldn’t have all of these thoughts.
So，why not just say “no” from the beginning？Maybe you feel like if you don’t show up at the meeting (by the way，it is not one you must attend)，your boss isn’t going to like you or your coworkers won’t respect you.Maybe you feel as if your mom，dad or sisters won’t love you as much if you don’t do everything for them what they ask every occasion.
If these people are your true friends，family members，or a good boss，they will like or love you the same no matter what.People treat you the way you teach them to，and if you’re someone who
always says “yes”，then that’s what they’re expecting.
You need to do what is right for you.Of course we do have real obligations in life to fulfill，but we do not have to do everything others want us to do.
【语篇解读】 生活中，我们有义务完成应该做的事情，但是不必出于太多的顾虑，凡事惟命是从，要学会拒绝，学会说“不”。
1．Which of the following statements would the writer agree with?
A．We should try to do what our friends ask us to do.
B．We should help others in need.
C．Always saying “yes” means you are dishonest.
D．Always saying “no” means you are brave.
解析 细节理解题。根据第二段第一句的内容可知，作者认为我们应该帮助需要帮助的人，故B项正确。
答案 B
2．Generally speaking，we agree to do what we hate to do because we________.
A．have a bad habit
B．have a kind heart
C．have much concern
D．have obligations
解析 推理判断题。结合第三段第二句中的“you think about it too much”以及本段后半部分的内容可推知，我们之所以同意做我们讨厌做的事情是因为我们有很多顾虑。
答案 C
3．The writer believes that if you say “no” to your family members，you’ll________.
A．have the same relationship with them as before
B．have a loose relationship with them
C．disappoint them
D．upset them
解析 细节理解题。根据倒数第二段第一句的内容可知，作者认为如果你对你的家人说“不”，他们与你之间的关系仍然会和以前一样。
答案 A
4．What would be the best title for the text?
A．Learn to Make a Right Choice
B．To Be Yourself
C．Do What You Want to Do
D．Learn to Say “No”
解析 主旨大意题。文章第一段就开门见山地点明了本文的中心话题，即要学会说“不”，所以D项作为本文的标题最合适。
答案 D
