Most people want to be happy, but few know how to find happiness. Money and success alone do not bring lasting happiness. Aristotle, a Greek thinker, said, "Happiness depends upon (取決于)ourselves." In other words, we make our own happiness. Here are a few suggestions（建議） to help you be happier.
The first secret of happiness is to enjoy the simple things in life. Too often, we spend so much time thinking about the future. For example, getting into college or getting a good job －that we fail to enjoy the present. You should enjoy life's simple pleasures, such as reading a good book, listening to your favorite music, or spending time with close friends. People who have several close friends often live happier and healthier lives.
Another secret to living a happy life is to be active, and have hobbies where you forget your problems and time. Many people experience this dancing, or playing a sport, such as swimming. You can forget about your problems, and only think about the activity.
Finally, many people find happiness in helping others. Studies show that people feel good when they spend their time helping others. If you want to feel happier, do good things for someone. You can help a friend with his or her studies, go shopping to buy food for an elderly person, or simply help out around the house by washing the dishes.
【小題1】The best title of the passage is______.
A．Money Makes You HappyB．The Secrets of Happiness

科目：初中英語(yǔ) 來(lái)源：2012屆四川省成都市玉林中學(xué)初三下學(xué)期期末考試英語(yǔ)試卷（帶解析） 題型：閱讀理解

Four years ago my sweet mom went to be with her Lord. She did it her way.
I got the call at work, and I headed home quickly. Mom and Dad lived on a small farm that they had owned since I was seven. I hated going there every weekend. There was nothing for a young girl to do but watch the one station on the old TV set, if the weather allowed reception（接收）.
My mom, on the other hand, loved the peace and quiet of the land and loved to work in the garden among her flowers and vegetables. The place was simple, with no indoor plumbing or heat. We had a big wood stove in the kitchen that did its best to heat the little farmhouse, but it always seemed cold and too quiet to me.
In the evenings, my mom and I would sit for hours singing in the little kitchen. I sang the melody and Mom harmonized. Her favorite song was "Moon River" and we sang it over and over. Mom told me stories about how when I was a little girl, I could sing before I could talk. She loved to tell how my playpen（嬰兒圈欄）sat in the kitchen next to the radio and there was one song I particularly loved called "Ivory Tower".
As time passed, I had my own children and went to visit the farm every week or two. The kids loved the farm and the tractor rides with my dad. Me, well, I still hated the silence of the farm. While my mom loved to sit at her kitchen table and look out at her garden and flowers and retell all the old stories, I missed the hustle and bustle（喧鬧）of my life at home. But I sat there listening quietly as she reminisced.
Now, I sat back in the silence and the silence was deafening so I finally leaned over to turn on an old radio. Music always comforted me.
My heart skipped a beat. "Moon River" was playing on the radio. I sat there stunned, with a tear running down my cheek, as I listened to every familiar note.
Then the radio announcer of this oldie station came on. "Here's one we haven't heard in a while," and an unfamiliar song began. I began to cry harder as I heard the words sung over the airwaves. “Come down, come down from your Ivory Tower...”.
【小題1】The writer didn’t like staying in the farm for the following reasons EXCEPT that
________.

A．it was too cold and quiet
B．she could only sing one song on the small farm
C．there was nothing more that could make her excited
D．The place was simple, with no indoor plumbing or heat
【小題2】From the first paragraph, we know that the writer’s mother ________.
A．passed away four years ago
B．left the small farm with Lord
C．left for Lord to live her own way
D．preferred to be with Lord
【小題3】The underlined word reminisced in the fifth paragraph probably means ________.
A．recalledB．comfortedC．shoutedD．sighed
【小題4】Which of the following statements is NOT true according to the passage _______.
A．The writer was able to sing before she could speak.
B．The writer preferred to live a busy life in the city.
C．The writer was still quite familiar with the song "Ivory Tower".
D．The writer treasured all her childhood memories in the small farmhouse.
【小題5】Which of the following would be the best title for this passage? _______
