For many employers, Facebook, MySpace and other social networking sites are already a threat （威脅） that cut into productivity．Now they have something else to worry about—the games hosted by these sites．
This new type of social gaming is called "asynchronous" gaming and allows people to play with their friends without having to be online at the same time．The low-intensity （低強(qiáng)度） engagement has made games such as FarmVille, Cafe World and Pet Society popular among employees who often log on during office hours．
"What we are seeing is that more and more people and organizations are recognizing the productivity lost so probably more chief information officers are blocking Facebook applications," Rebecca Wettemann of Nucleus Research said．
Boston-based Nucleus Research, which conducted a recent study into the effects of social networking sites on productivity, said nearly half of office employees in the United States access social networking sites at work, which leads to an average loss of 1．5 percent of total office productivity．
Facebook, which has 350 million users, says at least 20 percent of its members play games online．Sebastien de Halleux, CEO and co-founder of online game creator Playfish, said Asia is growing at a faster pace than other regions．"We had no idea that it would spread so fast．．．when we had 100,000 users after one month, we thought it was the biggest success ever．Now with 60 million users we think this is only the beginning of something much bigger," he added．
Zynga's FarmVille, the best known game with over 70 million active users to date, allows players to own a virtual farm where they can grow crops and raise animals．
While companies try to limit access to social networking sites, not everyone sees the games as harmful．
61．We can learn that Pet Society is a game _____．
A．popular among employers             B．without having to be online
C．merely played during office hours      D．that can be played online at a different time
62．It can be inferred from the passage that ____．
A．Playfish is owned by Sebastien and Rebecca
B．Playfish has over 70 million active users to date
C．Asia will be the largest potential market for Playfish
D．Playing online games loses 1．5 percent of total office productivity
63．The best title of the passage would be ____．
A．Social Network Gaming             B．New Threat to Productivity
C．Social Networking Sites              D．Latest Survey on Productivity
64．What would most probably be discussed next after the last paragraph?
A．Opinions in favor of online games．
B．Measures to limit access to social networking sites．
       C．Suggestions on how to improve productivity．
D．More examples about the bad effects of online games．

科目：高中英語(yǔ) 來(lái)源：2014屆四川棠湖中學(xué)外語(yǔ)實(shí)驗(yàn)學(xué)校高二4月月考英語(yǔ)試卷（解析版） 題型：閱讀理解

Our spiritual intelligence quotient (精神智商)，or SQ, helps us understand ourselves, and live fuller, happier lives.

Though we're all born with SQ, most of us don’t even realize that we have it. Fortunately, you don't have to sign up for classes to learn how to improve your SQ. Here are some simple steps that can lead you to this new level of understanding.

Sit Quietly. The process of developing spiritual intelligence begins with solitude (獨(dú)處) and silence. To tune in to your spirit, you have to turn down the volume (強(qiáng)度) in your busy, noisy, complicated life and force yourself to do nothing at all. Start small by creating islands for silence in your day. In the car, instead of listening to the music, use the time to think. At work, shut the door to your office between meetings, take a few breaths and let them out very, very slowly. Enjoy the stillness in your home after the kids are finally in bed.

Step Outside.  For many people, nature sets their spirit free. Go outside to watch a beautiful sunset. If you are walking with the dog, take the time to admire flower in bloom; follow the light of a bird and watch clouds float overhead.

Ask Questions of Yourself. Ask open-ended questions, such as "What am I feeling? What are my choices? Where am I heading?"

But don't expect an answer to arrive through some supernatural form of e-mail. "Rarely do I get an immediate answer to my question," says Reverend Joan Carter, a Presbyterian minister in Sausalito, California. “But later that day I suddenly find myself thinking about a problem in a perspective(角度) I never considered before.”

Trust Your Spirit. While most of us rely on gut(本能的) feeling to realize danger, spiritual intelligence pushes us, not away from, but towards some action that will lead to a greater good.

1.The passage is mainly about          .

A．what your SQ is and in what way it can benefit our life

B．what your SQ is and in what way it can be improved

C．the relationship between your SQ and your life

D．a(chǎn)dvantages and disadvantages of SQ

2.The underlined phrase "tune in to your spirit" in the third paragraph probably means to _____.

A．get your spirit relaxed                    B．keep up your spirit

C．keep seated quietly                      D．change your spirit

3.The author mentions the example of Reverend Joan Carter to show that            .

A．there are no immediate answers to your questions

B．e-mails can't keep working out a problem

C．the more questions you ask, the better answers you'll get

D．changing your way of thinking might help you solve a problem

根據(jù)短文內(nèi)容，從下框的A-F選項(xiàng)中選出能概括每一段主題的最佳選項(xiàng)。選項(xiàng)中有一項(xiàng)為多余項(xiàng)。

A．The secret of the writer’s success

B．A writer with enduring popularity

C．Well-received creation to encourage Brits

D．The insight into human nature

E. Writing styles in different stages

F. The story appreciate for school students

1. ____________

Charles Dickens is often thought of as one of England’s great writers. Yet for many his language is old-fashioned and his story plots often improbable. Why, Dickens, out of so many other great English writers, has made the list? How then to explain Dickens’s enduring popularity?

2. _____________

One reason undoubtly is the British government’s insistence that every child studies a Dickens novel at school. Alongside Willian Shakespeare, Charles Dickens is a compulsory (必讀的)writer on every English literature school reading list. His stories, though often over-long by today’s standard, are superbly written moral tales. They are filled with colorful characters.

3. ______________

But what makes his books stand out from other English writers is his insight into human nature. Dickens, like Shakespeare, tells us truths about human behavior that are as true to citizens of the 21st century as they were to his readers in the 19th century. Readers have returned to Dickens’s books again and again over the years to see what he has to say about readers’ own time.

4. _______________

The BBC adapted one of his less well-known novels, Little Dorrit, into a popular television drama that introduced many Brits to the novel for the first time. A dark story about greed and money, it was the perfect story to illustrate the bad times. No surprise then that it was Dickens Britons turned to, during the economic crisis last year, to make sense of world rapidly falling apart.

5. _______________

Readers of the 19th and early 20th century usually prized Dickens’s earlier novels for their humor and pathos(悲痛). While recognizing the virtues of these books, critics today tend to rank more highly the later works because of  their formal coherence and acute perception(洞察力) of the human condition. For as long as Dickens’s novels have something to say to modern audiences, it seems likely that he will remain one of Britain’s best loved writers.
