I am trying to muster(鼓起)the courage to toss away my mobile phone to enjoy a more peaceful and ring –free life.

Can you imagine not having your mobile phone? In our high-tech, in-a-hurry age, a cell-free life is a hard concept to swallow. Our mobile phones can now access the Internet, and many people feel the need to express their every thought on their blog pages. If I gave up my cellphone, people would think I was mad.

I wish I had the strength to toss away my technology . I have an office phone, a home phone, e-mail and if people want to contact me. they can. If I’m out, people can leave a message. Do they really need to find me 24/7 ? However, I’m a bit like Frodo in the movie Lord of the Rings. The power of the ring is too strong and I can’t let it go.

“Where have you been?” said a friend, who saw me a week after I lost my cell, “I tried calling you , but you disappeared. You disappeared off the face of the Earth。” See, when you don’t have a mobile phone, you don’t exist.

I’m not really going to toss my mobile phone away, in fact. We humans are such social animals and mobile phones serve us well. So in 2009, I’ve dicided not to serve my mobile phone. Like all machine, I can always turn it off.

科目:高中英语 来源: 题型:阅读理解

    Tuesday was the eighth day of the 12 th month on the Chinese lunar calendar. I first became aware of the day as a traditional festival called laba, or the eighth day of the winter month – when I was working in a factory 30 years ago.

At lunch time,some elder co-workers opened their lunch boxes, and out came the sweet smell of well-cooked rice porridge mixed with beans,nuts and dates(枣)and they talked excitedly. Then, I wondered why there should be such an unnecessary excitement over the  laba festival. Growing up during the “cultural revolution” (1966-1976), when almost all traditional things were considered out-of-date,I had scarcely become aware of most of the traditional festivals.

I really started to value and celebrate these traditional festivals when I began to write about  Chinese culture. It is really encouraging that, despite the dramatic changes and modernization that our country has experienced over the past three decades, people have come to treasure many of our traditions more. Some people may have a complaint against the extreme commercialization(商业化)of these traditional festivals, but I believe the business promotions have at least worked to increase people’s awareness.

Most of the traditional Chinese festivals are celebrated with feasts. No wonder that on Tuesday a lot of people were buying rice,nuts,dry fruit, and beans from supermarkets and stores. A few thousand went to the Yonghegong Lama Temple to make prays for peace and happiness.  

Now that we have celebrated laba festival,we are now looking forward to the Lunar New Year, when we are supposed to have a lot more feasts. In fact, it is reported that almost all popular restaurants have been booked out for the Lunar New Year Eve dinner in major cities across the country.

1.As a whole,the passage is mainly organized by_________.

    A.space               B.examples          C.time                 D.comparison

2.What is the writer’s attitude toward Chinese Festivals?

    A.He takes them seriously all the time.

    B.He values them more than before.

    C.He expects only the Lunar New Year.

      D.He thinks Chinese Festival are too commercialized.

3.The common ways to celebrate traditional Chinese festivals in the passage are to________.

       ① stop working in the factory               ② enjoy some special delicious food

       ③ have feasts with the family or friends     ④ pray for peace in temples

       ⑤ buy rice,nuts,fruits and beans         ⑥ write about Chinese culture

       A.①③⑤            B.②⑤⑥             C.①④⑥               D.②③④

4.From the last paragraph it can be inferred that now_________.   

       A.people are eager to show their richer life

    B.people have become tired of laba festival

    C.people are living a better life than before

       D.people are always active in celebrating festivals
