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?

Sometimes just when we need the power of miracles to change our beliefs， they materialize in the places we’d least expect. They can come to us as a drastic alteration in our physical reality or as a simple synchronicity in our lives. Sometimes they’re big and can’t be missed Other times they’re so subtle that if we aren’t aware， we may miss them altogether. They can come from the lips of a stranger we suddenly and mysteriously encounter at just the right instant. If we listen carefully, we’ll always hear the right words，at the right time， to dazzle us into a realization of something that we may have failed to notice only moments before.

On a cold January afternoon in 1989，I was hiking up the trail that leads to the top of Egypt’s Mt. Horeb. I’d spent the day at St. Catherine’s Monastery and wanted to get to the peak by sunset to see the valley below. As I was winding up the narrow path，I’d occasionally see other hikers who were coming down from a day on the mountain. While they would generally pass with simply a nod or a greeting in another language，there was one man that day who did neither.

I saw him coming from the last switchback on the trail that led to the backside of the mountain. As he got closer，I could see that he was dressed differently from the other hikers I’d seen. Rather than the high-tech fabrics and styles that had been the norm，this man was wearing traditional Egyptian clothing. He wore a tattered， rust-colored galabia and obviously old and thick-soled sandals that were covered in dust. What made his appearance so odd，though，was that the man didn’t even appear to be Egyptian！ He was a small-framed Asian man, had very little hair，and was wearing round，wire-rimmed glasses.

As we neared one another，I was the first to speak.“Hello，”I said，stopping on the trail for a moment to catch my breath. Not a sound came from the man as he walked closer. I thought that maybe he hadn’t heard me or the wind had carried my voice away from him in another direction. Suddenly he stopped directly in front of me on the high side of the trail， looked up from the ground， and spoke a single sentence to me in English，“Sometimes you don’t know what you have lost until you’ve lost it.”As I took in what I had just heard，he simply stepped around me and continued his descent down the trail.

That moment in my life was a small miracle. The reason is less about what the man said and more about the timing and the context. The year was 1989，and the Cold War was drawing to a close. What the man on the trail couldn’t have known is that it was during my Egyptian pilgrimage， and specifically during my hike to the top of Moses’s mountain，that I’d set the time aside to make decisions that would affect my career in the defense industry，my friends，my family，and，ultimately，my life.

I had to ask myself what the chances were of an Asian man dressed in an Egyptian galabia coming down from the top of this historic mountain just when I was walking up，stopping before me，and offering his wisdom，seemingly from out of nowhere. My answer to my own question was easy： the odds were slim to none！ In an encounter that lasted less than two minutes on a mountain halfway around the world from my home， a total stranger had brought clarity， and the hint of a warning， regarding the huge changes that I would make within a matter of days. In my way of thinking，that’s a miracle.

I suspect that we all experience small miracles in our lives every day. Sometimes we have the wisdom and the courage to recognize them for what they are. In the moments when we don’t，that’s okay as well. It seems that our miracles have a way of coming back to us again and again. And each time they do，they become a little less subtle ，until we can’t possibly miss the message that they bring to our lives！

The key is that they’re everywhere and occur every day for different reasons， in response to the different needs that we may have in the moment. Our job may be less about questioning the extraordinary things that happen in our daily lives and more about accepting the gifts they bring.

1.Why did the author make a pilgrimage to Mt. Horeb in Egypt?

A.He was in search of a miracle in his life.

B.It was a holy place for a religious person to head for.

C.He intended to make arrangements for his life in the future.

2.What does the underlined part “my own question” refer to in Paragraph 6?

A.For what reason did the man stop before me?

B.Why did the Asian man go to the mountain?

C.What change would I make within a matter of days?

D.What was the probability that others told us the right words?

3.Which of the following is closest in meaning to the underlined word “subtle” in Paragraph 7?

C.Precise. D.Sufficient.

B.his words were in perfect response to the need he had at that moment

C.what the Asian man said was abundant in the philosophy of life

Sometimes just when we need the power of miracles to change our beliefs, they materialize in the places we’d least expect. They can come to us as a great change in our physical reality or as a simple coincidence in our lives. Sometimes they’re big and can’t be missed. Other times they’re so subtle that if we aren’t aware, we may miss them altogether. They can come from the lips of a stranger we suddenly and mysteriously meet at just the right instant.

Sometimes just when we need the power of miracles, they arise in the places we would least expect.

On a cold January afternoon in 1989, I was climbing Egypt’s Mt. Horeb, hoping to get to the peak by sunset to see the valley below. As I was winding up the narrow path, I’d sometimes see other hikers who were coming down. While they would generally pass with simply a nod or a greeting in another language, there was one man who did neither.

I saw him coming and as he got closer, I could see that, unlike other hikers, he was wearing traditional Egyptian galabia( 长 袍 ). What made his appearance so strange was that the man didn’t even appear to be Egyptian, but was a small-framed Asian man with little hair and round glasses.

As we neared one another, I said Hello, but not a sound came from him. I thought maybe he hadn’t heard me. Suddenly he stopped directly in front of me, looked up from the ground, and spoke a single sentence to me in English, “Sometimes you don’t know what you have lost until you’ve lost it.” As I took in what I had just heard, he simply stepped around me and continued his going down.

That moment in my life was a small miracle. The reason is less about what the man said but more about the timing and the context.

I had to ask myself what the chances were of an Asian man dressed in an Egyptian galabia coming down from the top of this historic mountain just when I was walking up, stopping before me, and offering his wisdom, seemingly from out of nowhere. My answer to my own question was easy: nearly no chance! In a meet that lasted less than two minutes, a total stranger had brought something clear and something of a warning, regarding the huge changes that I would make within a matter of days. In my way of thinking, that’s a miracle.

Miracles are everywhere and occur every day for different reasons, in response to the different needs that we may have in the moment. Our job may be less about questioning the extraordinary things that happen in our daily lives and more about accepting the gifts they bring.

1.Before the Asian man spoke, how did the author think about him?

A.He was very rude and strange.

B.He was different from others.

C.He was shy and nod to strangers.

D.He looked ordinary and was talkative.

2.Why did the author make a pilgrimage to Mt Horeb in Egypt ?

A.He was in search of a miracle in his life.

C.What change would I make within a matter of days ?

D.What was the probability that others told us the right words ?

4.Why did the author view the meet with the Asian man as a miracle in his life?

A.Because the Asian man’s appearance had a deciding effect on his future life.

B.Because his words were in perfect response to the need he had at that moment.

C.Because what the Asian man said was meaningful in the philosophy of life.

D.Because the Asian man impressed on him the worth of what he had possessed.

5.What might be the best title for the passage ?

A.Can you recognize a miracle? B.Is a miracle significant to us?

高三英语阅读理解中等难度题查看答案及解析

One of the newest “smart” devices is an old favorite, a camera. And smart cameras are getting smarter all the time. Some are now built with machine learning tools to help them think for themselves. Machine learning involves patting large amount of data into a computer for processing.

Google Clips

One of the latest to launch is Google Clips. It is the first camera developed by the web search giant that is not built into a phone.

The small and light device is designed to be put somewhere in a room to take pictures by itself. It can also be stuck to an object or a person’s clothing.

Google says machine learning helps the camera choose the best times and situations for taking pictures and video clips. It can also recognize the faces of people or pets chosen by the user and take pictures of them in a more natural way.

The device is not yet being sold, but interested buyers can join a waiting list to be informed when it is available.

GoPro Hero

GoPro is another company developing machine learning technology. GoPro also uses machine learning to power its QuikStories feature. This tool takes existing photos and videos and automatically creates a finished video piece, complete with music and effects.

Snap Spectacles

Messaging app Snapchat sells a pair of sunglasses with a built-in camera that can record short video clips with the push of a button. Snap Inc. says the product, called Spectacles, is designed to “capture the moment, without taking you out of it.” Many smart phones already have facial recognition technology built into the devices.

Snap Inc. has started selling its Spectacles sunglasses online in the United States.

Apple iPhone X

Apple’s new iPhone X is being launched with its new Face ID system that it says will unlock the phone just by having the user look at it. This replaces the Touch ID on previous devices that used a fingerprint to unlock the phone.

Apple says the system works by projecting more than 30,000 dots on the face to create a kind of map. Apple claims its facial recognition is even secure enough to allow payments through its Apple Pay service.

1.What can machine learning tools help cameras do?

A.Get much smarter. B.Process more roughly.

C.Keep data for ever. D.Store more natural photos.

2.What can we know about Google Clips?

A.It can only be put in a room.

B.People can buy it online easily.

C.It can be built into a phone,

D.You can take photos automatically with it.

3.What is the special function of GoPro Hero?

A.It has to use power to work.

B.It can record videos vividly.

C.It provides music and effects for videos.

D.It uses technology of machine learning.

4.Which of the following can now be bought surely on the Internet?

A.Google Clips. B.GoPro Hero.

C.Spectacles sunglasses. D.Apple iPhone X.

5.How is Apple iPhone X unlocked?

A.By a fingerprint. B.By facial recognition.
