Speed-reading is an indispensable skill in the Internet age. We skim over articles, e-mails and tweets to try to grasp key words and the essential meaning of a certain text. Bombarded with information from our electronic devices, it would be impossible to cope（应付）if we read word by word, line by line.
But a new trend calls on people to unplug and enjoy reading slowly, listing benefits beyond intellectual stimulation.
A recent story from The Wall Street Journal reported on a book club in Wellington, New Zealand, where members meet in a cafe and turn off their smart phones. They sink into cozy chairs and read in silence for an hour.
Unlike traditional book clubs, the point of the Slow Reading Club isn’t exchanging ideas about a certain book, but to get away from electronic devices and read in a quiet, relaxed environment. According to the Journal, the Wellington book club is just one example of a movement initiated (发起) by book lovers who miss the old-fashioned way of reading before the Internet and smart phones.
Slow readers, such as The Atlantic’s Maura Kelly, say a regular reading habit sharpens the mind, improves concentration, reduces stress levels and deepens the ability to empathize.
Some of these benefits have been backed up by science. For example, a study of 300 elderly people published by the journal Neurology last year showed that regular engagement in intellectually strenuous activities like reading slowed the rate of memory loss later in life.
Slow reading means a return to an uninterrupted pattern in a quiet environment free of distractions. “Aim for 30 minutes a day,” advises Kelly from The Atlantic. “You can squeeze in that half hour pretty easily if only during your free moments – whenever you find yourself automatically firing up your laptop to check your favorite site, or scanning Twitter for something to pass the time – you pick up a meaningful work of literature,” Kelly said. “Reach for your e-reader, if you like. Kindles make books like War and Peace less heavy, not less substantive(真实的), and also ensure you’ll never lose your place.”

Here's a hotel worth writing something about: a company in Poland plans to build tourist accommodation under the sea. The structure can be dragged to a suitable location and placed on supports on the sea bed. The ‘Water Discus’ will be made up of an underwater disc containing 22 bedrooms with sea views, connected by lift and stairs to a disc above the surface containing other hotel facilities.
Project manager Robert Bursiewicz says: “Nowadays it's possible to build submarines ('潜艇) which go deeper than 500m below the sea surface, so building an underwater hotel is not a problem. ”
In fact, they don't plan to have the hotel very deep. Water acts like a filter (过滤器) for sunlight, and below 15m most colors, apart from blue, are washed out. And we all want to see colorful marine life, don't we?
But this isn't the first hotel to offer underwater views from the bedrooms. The two-bedroom Jules' Undersea Lodge, off the coast of Florida, has been taking in guests 10m beneath the surface since 1986.
The company that operates the hotel also runs a diving course for beginners to help get guests down and into the hotel. It is accessible only through an opening at the bottom.
And you'll find all the usual facilities in the room, according to Teresa McKirma, Jules's chief financial officer. It has a television, air conditioning and Wi-Fi. But for the staff, simple things like cleaning and making beds can be challenging, since the lodge is in sea water.
"It actually takes quite a lot of work to get anything down there," she says. "We have to put everything in waterproof boxes and attach weights to them to counter their buoyancy (浮力). "
The hotel has suitably sized waterproof boxes so that pizzas can be delivered by divers to guests who order them for their evening meal. And after a meal, if you can't sleep because of the excitement of the experience, you don't have to count sheep. You'll fall asleep quicker if you count fish.
1.According to the passage, the new hotel will ______.
A. contain three discs B. come into use soon
C. have a movable structure D. be built 500m beneath the surface
2.Why won't they plan to have the hotel very deep in the water?
A. They have financial problems.
B. They lack advanced technology.
C. They refuse to enjoy colorful life.
D. Most colors are washed out below 15m.
3. According to Teresa McKirma, ______.
A. entertainment is impossible in the hotel
B. the staff's work is difficult to finish
C. it's easy to get things down there
D. the built hotel is badly equipped
4.What can be inferred from the last paragraph?
A. Passengers can't enjoy their meals.
B. Passengers will feel fed up with the views.
C. Passengers have no choice but to count fish.
D. Passengers may get excited about the experience.

Conventional wisdom says that hardship can make us old before our time. In fact, a new study suggests that violence not only leaves long-term scars on children?s bodies, but also changes their DNA, causing changes that are equal to seven to ten years of premature aging.
Scientists measured this by studying the ends of children?s chromosomes(染色体), called telomeres, says Idan Shalev, lead author of a study published in Molecular Psychiatry.
Telomeres are special DNA sequences which prevent the DNA in chromosomes from separating. They get shorter each time a cell divides, until a cell cannot divide any more and dies.
Several factors have been found to shorten telomeres, including smoking, radiation and psychological stresses such as being treated badly when young and taking care of a chronically ill person.
In this study, researchers examined whether exposure to violence could make children’s telomeres shorten faster than normal. They interviewed the mothers of 236 children at ages 5, 7 and 10, asking whether the youngsters had been exposed to domestic violence between the mother and her partner; physical maltreatment by an adult; or bullying. Researchers measured the children’s telomeres—in cells obtained by swabbing the insides of their cheeks—at ages 5 and 10.
Telomeres shortened faster in kids exposed to two or more types of violence, says Shalev. Unless that pattern changes, the study suggests, these kids could be expected to develop diseases of aging, such as heart attacks or memory loss, seven to 10 years earlier than their peers.
Shalev says there is hope for these kids. His study found that, in rare cases, telomeres can lengthen. Better nutrition, exercise and stress reduction are three things that may be able to lengthen telomeres, he says.
The study confirms a small but growing number of studies suggesting that early childhood adversity imprints itself in our chromosomes, says Charles Nelson, a professor of pediatrics and neuroscience at Harvard Medical School.

A. hardship can change a child?s aging

2.According to the text, telomeres ________.

B. can help prevent DNA from separating

3.Which of the following is TRUE according to the text?
A. Violence can cause quick cell division in children?s body.
B. Researchers measured the children?s telomeres from their legs in the study.
C. Being treated badly will make a child?s telomeres shorten faster.
D. Children who have shorter telomeres may have a heart attack earlier.
4.What is the best title for the text?
A. Violence Aging Children?s DNA
B. Children?s Changing DNA Patterns
C. Violence and Telomeres
D. The Function of Telomeres
