“Nomophobia”, NO Mobile Phone phobia(恐惧) is a 21st-century term for the fear of not being able to use your smartphone. Smartphone addiction is on the rise, surveys show, and a new study released adds to a growing body of evidence that smartphone addiction is harming our minds literally.

Smartphone addiction affects many people from all across the globe. Over 1.8 billion people own smartphones and the average owners check their screens 150 times a day. Considering those numbers, it shouldn’t come as a surprise when 44% of people (compared with 20% in 2011) admit feeling anxious when they can’t have access to their phones.

Researchers from Harvard University used brain imaging to study the brains of 19 teenage boys who were diagnosed with smartphone addiction. Compared with 19 teenagers who were not addicted, the brains of the addicted boys had significantly higher levels of GABA, which decelerates neurons (神经元)， than levels of glutamate-glutamine, which energizes brain signals. That results in poorer attention and control, which you don’t want to have, because you want to stay focused. So that means you are easier to get distracted.

“Addicted teenagers in the study also had significantly higher scores in anxiety, depression and levels of impulsiveness (冲动) ,” said Dr. Leslie Perlow, who led the study.

If you seem to have the symptoms of smart device addiction, experts have some suggestions in addition to mindfulness training. First, turn off your phone at certain times of the day, such as in meetings, when having dinner, playing with your kids, and of course, driving. Remove social media apps, like Facebook and Twitter from your phone, and only check-in from your laptop. Try to stop yourself to 15-minute intervals at set times of the day when it won’t affect work or family life. Don’t bring your cellphone and its harmful blue light to bed, and use an old-fashioned alarm to wake you. And last, try to replace your smart device time with healthier activities such as meditating or actually interacting with real people.

1.What is the conclusion of the research?

A.Smartphone addiction leads to distraction.

B.Smartphone addiction easily causes anger.

C.Smartphone addiction is harmful to the mind.

D.Smartphone addiction brings about anxiety and depression.

2.Where can you find the data that best supports smartphone addiction is on the rise?

A.In Paragraph 2. B.In Paragraph 3.

C.In Paragraph 4. D.In Paragraph 5.

3.Which of the following can replace the underlined word “decelerates” in Paragraph 3?

A.Speeds up. B.Slows down.

C.Adds to. D.Cuts down.

4.Which of the suggestions is encouraged according to the text?

A.To use an old-fashion cellphone. B.To participate in more social activities.

C.To stop fifteen-minute intervals. D.To turn off the blue light on bed.

A sunflower is a sunflower . A mobile phone is a mobile phone . But can you combine the two to do something for your local environment?

As early as next year it may well be possible. When you have finished with your mobile phone you will be able to bury it in the garden or a plant pot and wait for it to flower. A biodegradable (能进行生物递降分解的) mobile phone was, this month, introduced by scientists.

Scientists have come up with a new material over the last five years. It looks like any other plastic and can be hard or soft, and able to change shape. Overtime it can also break down into the soil without giving out any toxic chemicals. British researchers used the new material to develop a phone cover that contains a sunflower seed. When this new type of cover turns into waste, it forms nitrates (硝酸钾). These feed the seed and help the flower grow. Engineers have designed a small transparent window to hold the seed. They have made sure it only grows when the phone is thrown away. "We've only put sunflower seeds into the covers so far. But we are working with plant experts to find out which flowers would perform best. Maybe we could put roses in next time," said one scientist.

As phone technology is developing so quickly people are constantly  throwing their mobiles away. This means manufacturers are under pressure to find ways of recycling them. Some 650 million mobile phones have been sold this year. Most of them will be thrown away within two years, adding plastic, heavy metal and chemical waste to the environment. A biodegradable cover can offer some relief for nature, according to the scientists. "The seed is released and the flower grows in the pot so you don't have to concern yourself with the phone when you have finished using it," said Kerry Kirwan. She leads the research team, which is based at the University of Warwick in Britain.

1. The main idea of the passage is ________ .

2. The purpose of introducing a biodegradable mobile phone is ______ .

3. What is the possible meaning of the underlined word ?

4.Which of the following statements is NOT true ?

Change is everything in the case of mobile phones. Recent research indicates that the mobile phone is changing not only our culture, but our very bodies as well.

First, let’s talk about culture. The difference between the mobile phone and the fixed-line phone, is that a mobile number corresponds to a person, while a fixed-line phone goes to a place. If you call my mobile, you get me. If you call my fixed-line phone, you get whoever answers it.

This has several implications（含义）. The most common one, however, and perhaps the thing that has changed our culture forever, is the “meeting” influence. People no longer need to make firm plans about when and where to meet. Twenty years ago, a Friday night would need to be arranged in advance. You needed enough time to allow everyone to get from their place of work to the first meeting place. Now, however, a night out can be arranged on the run. It is no longer “see you there at 8”, but “text me around 8 and we’ll see where we all are.”

Texting changes people as well. In their paper, “Insights into the Social and Psychological Effects of SMS (Short Message Service) Text Messaging”, two British researchers distinguished between two types of mobile phone users: the “talkers” and the “texters”－those who prefer voice to text messages and those who prefer text to voice.

They found that the mobile phone’s individuality and privacy gave texters the ability to express a whole new outer personality. Texters were likely to report that their family would be surprised if they were to read their texts. This suggests that texting allowed texters to present a self-image that differed from the one familiar to those who knew them well.

Another scientist wrote of the changes that mobiles have brought to body language. There are two kinds that people use while speaking on the phone. There is the “speakeasy”: the head is held high, in a self-confident way, chatting away. And there is the “spacemaker”: these people focus on themselves and keep out other people.

Who can blame them? Phone meetings get cancelled or reformed and camera-phones intrude（侵入）on people’s privacy. So, it is understandable if your mobile makes you nervous. But perhaps you needn’t worry so much. After all, it is good to talk.

1.The “meeting” influence of a mobile phone refers to the fact that ________.

A. people are able to meet someone at any place and any time

B. people have to make a firm plan about when and where to meet

C. people can arrange their meeting place and time more flexibly

D. people have to attend more phone meetings than ever before

2.We can infer from Paragraph 5 that the texts sent by texters probably are ________.

A. showing popular images to others

B. showing new images to others

C. showing the same images to others

D. showing familiar images to others

3.According to the passage, who is afraid of being heard while talking on the mobile?

A. talkers　　 　　 　　 B. the “spacemaker”

C. the “speakeasy”　 D. texters

4.Which of the following can be the best title of the passage?

A. The Influence of Short Message Service B. Changes in the Use of the Mobile

C. Changes Caused by Mobile Phone Use D. Body Language and the Mobile Phone

Third-generation mobile phones, known as 3G, are the next big step for the telecom(电信) industry. Data speed in 3G networks is much quicker than that in present technology. This means users can have high-speed Internet access(上网) and enjoy video and CD-quality music on their phones.

"Mobile data is not a dream; it's not an option(选择) but a requirement" said Len Lauer, head of a US communications company, Sprint PCS, at a 3G conference in Bangkok earlier this month.

With 3G, you can forget about text messages telling you yesterday's news; a 3G phone can receive video news programs, updated(更新) four times a day. Internet access will also be much quicker, making it easier to surf the Web on your phone than on your computer at home.

Don't worry about getting lost. 3G phones offer map services so you can find a new restaurant just by pressing a few keys on your handset(手持机).

However, the most impressive part of 3G technology is video calling. With live two-way video communication, you can have face-to-face talks with friends and family on your mobile phone.

Many European countries have already launched the service. In May 2000 the US Government issued five licenses(许可证) to run 3G wireless services, while the first 3G phones arrived in Italy in March this year.

International telecom companies can't wait to sell 3G in China, the world's largest mobile telecommunications market. But they will have to be patient. At the moment, China is busy testing its 3G-based technologies, networks and services. This will be followed by a trial period before the phones can finally hit the shops.

“We need to create a pool of 3G customers before the large-scale commercial launch(开始) of the service,” said Fan Yunjun, marketing manager for Beijing Mobile. “We expect that the 3G licenses will be issued(发行) late next year.”

We'll also see 3G services enter our daily lives in all-sorts of new ways, from shopping and banking to playing interactive computer games over the net. It won't be long before we think nothing of sitting on a train using a mobile palmtop(掌上型电脑) to check our bank accounts or pay bills. You might even click on an icon(图标) on the screen to set up an immediate video-conference with your bank clerk.

67. 3G is ______.

A. a kind of mobile phone that can send text message and make calls

B. a kind of technology that makes mobile data and video calling come true

C. a kind of player that can be used to listen to CD or MP3 music

D. a kind of system that makes it easy to surf the Internet

68. What does Len Lauer want to inform the readers?

A. Realizing the dream of mobile data based on the application of 3G is a must.

B. There is no need to send messages since 3G can receive video news programs.

C. 3G is supposed to own all the functions that a computer has.

D. It is a choice to carry mobile data with 3G phones.

69. The 3G services can be launched after the following steps EXCEPT that ________.

A. they have to test its 3G-based technologies, networks and services

B. they need to create a group of 3G customers

C. the 3G licenses are issued and 3G phones are tested

D. international telecom companies decide to sell 3G in China

70. The last paragraph shows us that ________.

A. 3G services bring a lot of convenience to us

B. we cannot live without 3G mobile phones

C. 3G services can change our life completely

D. 3G services will take the place of other technologies

Britain’s symbolic red phone boxes have become out of date in the age of the mobile, but villages across the country are stepping in to save them, with creative intelligence. Whether as a place to exhibit art, poetry, or even as a tiny library, hundreds of phone boxes have been given a new life by local communities determined to preserve a typical part of British life. In Waterperry, a small village near Oxford, the 120 residents have filled the phone box next to the old house with a pot of flowers, piles of gardening and cooking magazines, and stuck poems on the walls.

They took control of the phone box when telecoms operator BT said it was going to pull it down, an announcement that caused such dissatisfaction that one local woman threatened to chain herself to the box to save it. “I’d have done it, “ insisted Kendall Turner. “It would have been heartbreaking for the village. “ Local councilor Tricia Hallam, who came up with the idea for the phone box’s change, said quite a few people would have joined her, adding, “ We couldn’t let it go because it’s a British symbol.”

Only three feet by three feet wide, and standing 2.51-meter tall, the phone boxes were designed by Giles Gilbert Scott in 1936 for the 25^th anniversary of the reign of King George V. Painted in “Post Office red” to match the post boxes, they were once a typical image of England and the backdrop(背景) to millions of tourist photographs.

Eight years ago there were about 17,000 across Britain, but today, in a country where almost everybody has a mobile phone, 58 percent are no longer profitable and ten percent are only used once a month. “On average, maintaining them costs ￡800 a year per phone box-about ￡44 million annually,” said John Lumb, general manager for BT Payphones.

1.Some red phone boxes in Britain have been used for ____.

a. selling flowers    b. cooking   c. reading  d. exhibiting art or poetry

2.Why do the villagers want to keep the red phone boxes?

3.What is the color of the British post boxes according to the passage?

4.What is John Lumb’s attitude towards pulling down the red phone boxes?
