Smart devices are sometimes powerful. They put a world of information at our fingertips. ―1.That is a huge blessing for parents seeking flexible work hours. Smart phones and tablets can also promote efficiency by allowing people to get things done in spare moments that would otherwise be wasted, such as while queuing for coffee. They can even help lazybones create the false impression that they are working around the clock, by programming their e-mail to be sent at 1 am.

But for most people, the servant has become the master. Not long ago only doctors were on call all the lime. Now everybody is. Bosses think nothing of invading their employees' free time. 2. Even people with strong mind check their smart devices with heavy addiction, even during pre-dinner drinks, and send e-mails first thing in the morning and last thing at night.

3. How can we harvest the benefits of connectivity without becoming its slaves? One solution is digital dieting. Just as the abundance of junk food means that people have to be more disciplined about their eating habits, 4. Maybe the only way to break the 24/7 habit is to act together rather than individually. The firms should introduce rules about when people are expected to be offline, and encourage them to work together to make this possible.

We must be aware that the faster smart devices become and the more addictive the apps that are designed for them, the stronger the addiction will grow. 5.

A. This is partly because smart devices are addictive.

B. Work invades the home far more than domestic chores invade the office.

C. Now it's time to outsmart the smart devices by insisting that everyone turn them off from time to lime.

D. the abundance of junk information means we have to be more disciplined about our browsing habits.

E. Banning texting at weekends can really show the iPhone who is boss.

F. They enable people to work at home instead of crowding into the subway with smelly strangers.

G. What can be done to keep smart devices in their place?

高三英语七选五中等难度题查看答案及解析

A device that stops drivers from falling asleep at the wheel is about to undergo testing at Department of Transport laboratories and could go on sale within 12 months.

The system, called Driver Alert, aims to reduce deadly road accidents by 20% - 40% that are caused by tiredness. Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to fatigue.

Driver Alert is based on a computerized wristband. The device, worn by drivers or pilots, gives out a sound about every four minutes during a car journey. After each sound the driver must respond by squeezing the steering wheel. A sensor in the wristband detects this pressing action and measures the time between the sound the driver’s response.

Tiredness is directly related to a driver’s response time. Usually, a watchful driver would take about 400 milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy.

In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the driver’s response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible.

The device has been delivered to the department’s laboratories for testing. If these tests, scheduled for six months’ time, are successful, the makers will bring the product to market within about a year.

1.According to the text, Driver Alert ______.

A．aims to reduce tiredness-related accidents

B．has gone through testing at laboratories

C．aims to prevent drivers from sleeping

D．has been on sale for 12 months

2.How should a driver respond to the sounds from Driver Alert?

A．By sounding a warning.                   B．By touching the wristband.

C．By checking the driving time.               D．By pressing the steering wheel.

3.We can learn form the text that the driver needs to stop for a break when his response time is ______.

A．about 400 milliseconds                   B．below 500 milliseconds

C．over 500 milliseconds                    D．about 4 minutes

4.When the driver gets sleepy while driving, Driver Alert ______.

A．moves more regularly                    B．stops working properly

C．opens the window for the driver            D．sounds more frequently and loudly

高三英语阅读理解困难题查看答案及解析

No one can deny that buttons are an important clothing device. But, can they rise to the level of art? Organizers of an exhibit in New York think so.

Peter Souleo Wright organized “The Button Show” at Rush Arts Gallery in the Chelsea neighborhood of Manhattan. Eleven artists used the small, ordinary objects to create sculptures, portraits and wearable art. Some of the works are political, some are personal and others are just fun.

Wright said each artist reimagines and repurposes the buttons to make art. “What I tried to do with this show,” he said , “was to look at artists who were promoting that level of craft.”

He said he wanted the button art to be comparable to a painting “because of the amount of detail and precision in the work”.

Artist Beau McCall produced “A Harlem Hangover”. It looks like a wine bottle that fell over on a table. A stream of connected red buttons hang over the side, like wine flowing down. Similar red buttons form a small pool on the floor.

McCall layers buttons of different shapes and sizes to create the bottle. The stitching that holds them together is also part of the artistic design.

For San Francisco-based artist Lisa Kokin, buttons are highly personal. After her father died in 2001, she created a portrait of him using only buttons. That memorial to her father led to other button portraits, including those of activists Rosa Parks and Cesar Chavez.

Others use buttons for details. Artist Amalia Amaki of Tuscaloosa, Alabama, placed them on and around old photographs. Los Angeles artist Camilla Taylor attached buttons to three large sculptures that look like headless animals with long , narrow legs.

“The Button Show” ends at March 12. The Rush Philanthropic Arts Foundation paid for the exhibition. The foundation was created in 1995 by the Simmons brothers: artist Danny, hip-hop producer Russell and rapper Rev. Run. The foundation seeks to bring the artists to urban youth and to provide support for new artists.

1.Why did Wright organize “The Button Show”?

A. To show the importance of buttons.

B. To support the new artists.

C. To raise the button show to the level of art.

D. To create sculptures and portraits.

2.Whose works are personal?

A. Peter Souleo Wright.            B. Beau McCall.

C. Lisa Kokin.                    D. Amalia Amaki.

3.If you want to see “The Button Show”, you should ________.

A. buy tickets before March 12

B. phone Peter Souleo Wright before March 12

C. go to Rush Arts Gallery

D. go to the Rush Philanthropic Arts Foundationn
