You get anxious if there’s no wi-fi in the hotel or mobile phone signal up the mountain. You feel upset if your phone is getting low on power and you secretly worry things will go wrong at work if you’re not there. All these can be called “always on” stress caused by smart phone addiction.

For some people, smart phones have liberated them from the nine-to-five work. Flexible working has given them more autonomy in their working lives and enabled them to spend more time with their friends and families. For many others though, smart phones have become cruel masters in their pockets, never allowing them to turn them off and relax.

Pittsburgh-based developer Kevin Holesh was worried about how much he was ignoring his family and friends in favor of his iPhone. So he developed an app — Moment — to monitor his usage. The app enables users to see how much time they’re spending on the device and set up warnings if the usage limits are broken. “Moment’s goal is to promote balance in your life,” his website explains. “Some time on your phone, some time off it enjoying your loving family and friends around you.”

Dr. Christine Grant, an occupational psychologist at Coventry University, said, “The effects of this ‘a(chǎn)lways on’ culture are that your mind is never resting, and you’re not giving your body time to recover, so you’re always stressed. And the more tired and stressed we get, the more mistakes we make. Physical and mental health can suffer.”

And as the number of connected smart phones is increasing, so is the amount of data. This is leading to a sort of decision paralysis (癱瘓) and is creating more stress in the workplace because people have to receive a broader range of data and communications which are often difficult to manage. “It actually makes it more difficult to make decisions and many do less because they’re controlled by it all and feel they can never escape the office,” said Dr. Christine Grant.

1.What’s the first paragraph mainly about?

A. The popularity of smart phones.

B. The progress of modern technology.

C. The signs of “always on” stress.

D. The cause of smart phone addiction.

2.Kevin Holesh developed Moment to __________.

A. research how people use their mobile phones

B. help people control their use of mobile phones

C. make people better use mobile phones

D. increase the fun of using mobile phones

3.What’s Dr. Christine Grant’s attitude towards “always on” culture?

A. Confused. B. Positive.

C. Doubtful. D. Critical.

4.According to the last paragraph, a greater amount of data means __________.

A. we will become less productive

B. we can make a decision more quickly

C. we will be equipped with more knowledge

D. we can work more effectively

We always read reports about costs of oil going up and we will think this is our most valuable material. However, water is the most valuable resource(資源). People in the Middle East are more worried about this than oil. Maybe the next war will be about water.

In the future, to control the quality and quantity(數(shù)量), you will use different water for different usages. The water used to wash your car, water your flowers or wash your clothes doesn’t need to be as clean as the water you drink.

Traditional management of the water industry has been out of date since the 1990s. When technologies develop so rapidly in the world, we have loads of information for technologies in the business world, but in the water industry we don’t have any.

Reading is a great way to improve your English. By reading, you are receiving valuable language input. As you’re reading, you’re taking in language naturally, and you’re seeing how it all fits together. This is crucial to your learning.

The key to effective reading is to read things that you want to read. There are millions of books, magazines and websites out there. You couldn’t possibly read them at all. So the important thing is to find things that you like reading. Then, you’ll be motivated to read. And then the reading won’t be difficult. It’ll be easy! And then you’ll learn. It’s simple.

Remember: read what you want to read—what you like reading and what motivates and inspires you. But where can you start? Well, you could read a book that you’ve already read in your own language first, then in English. Magazines are also great. Find one that covers a topic you’re interested in: business, clothing, cooking…you name it, they’ll have it. Why not join a forum(論壇)？Go to google Groups，which has discussion groups based on common interests. Just type in the topic that interests you and join the chat.

Finally, how you read is also important. The best thing is to read without using a dictionary. Let the words flow over you. Just skip the parts you don’t understand. If you make your reading feel too much like work, it’ll stop being fun. Of course, you could make a note of any new words and phrases that you like or see repeated frequently, but try not to break your concentration too much. Also, set yourself mini-objectives. For example, if you’re reading a novel, read 20 pages a day. Very soon, you have been exposed to thousands of useful phrases and words. Have fun reading! You’ll learn so much!
