It sounds almost too good to be true，but a new study on sleeping brains suggests that listening to languages while you sleep can actually help you to learn them．
For the study，researchers played recordings of foreign words and their translations to subjects enjoying slow-wave sleep，a stage when a person has 1ittle consciousness of their environment．To ensure that the results were not compromised by foreign language words that subjects may have had some contact with at some point in their waking lives，researchers made up totally nonexistent foreign words．
When the subjects woke up，they were presented with the made-up words again without their translations．The subjects were then asked to imagine whether this made-up word indicated an object that was either smaller or larger．This vague(模糊的)way of testing their understanding of the words is an approach that is supposed to tap into the unconscious memory．
Unbelievably，the subjects were able to correctly classify the words in this way at an accuracy rate that was 10 percent higher than random chance．That’s not a rate high enough to have them suddenly communicating in a foreign tongue，but it is enough to suggest that the brain is still absorbing information on some level，even during sleep．
Researchers have long known that sleep is important for memory，but previously its role in memory was thought to relate only to the preservation and organization of memories acquired during wakefulness．This is the first time that memory formation has been shown to be active during sleep．
In other words，our brains are listening to the world，and learning about it，even when our conscious selves are not present．
The next step for researchers will be to see if new information can be 1earned quicker during wakefulness if it was already presented during sleep．If so，it could forever change how we train our brains to learn new things．Sleep learning might become a widespread practice．

In America，the number of people killed in car crashes in 2016 was above 40，000 for the first time in a decade，data released on Wednesday shows．
“Americans believe there is nothing we can do to stop crashes from happening，but that isn't true．We are behind the rest of the developed world in addressing highway fatalities(死亡)．We just haven't been willing to do what needs to be done，”said Deborah A．P．Hersman，president of the National Safety Council．
The National Safety Council data shows a 6 percent increase in deaths in 2018 when compared with 2015 and a 3 percent increase in the number of miles Americana drove in 2016．
“Motor vehicle fatality numbers have been ringing the alarm for two years，”Hersman said．“Unfortunately，we have been blind to the data and the killings on our roadways．If we fail to take action，the death tell will continue to rise．”
“The trend is clear：After years of progress，highway deaths are heading in the wrong direction，”said Jonathan Adkins，a state safety official．
The number of people killed reached a record low of 32，675 in 2014，according to NHTSA statistics．That record followed a fairly steady downward track for the past six years that experts attributed it primarily to safety features that have been built into cars and trucks．
Safety advances including increased seat-belt use，air bags，anti-lock braking，stability controls and electronic warnings and cameras．
The bad economy and high gas prices also influenced the reduction in deaths．Now，with unemployment and gas prices both low，more people are driving for work and pleasure trips．
“It’s not just that Americans drive more miles when the economy improves ；it’s the kind of miles they drive，”said Adrian Lund，president of the Insurance Institute for Highway Safety．
1.What’s Hersman’s attitude towards the present situation?
A. It has been getting better． B. It can hardly be improved．
C. The efforts are far from enough． D. Much work hart already been done．
2.What do we learn about the number of highway deaths in 2013 in America?
A. It’s lower than that in 2014． B. It’s lower than that in 2010．
C. It’s the lowest in recent years． D. It’s the highest in recently years．
3.What will happen with the economic recovery?
A. The gas prices will go up． B. The gas price will go down．
C. There will be more highway deaths． D. There will be fewer highway deaths．
4.What would be the best title for the passage?
A. Traffic Deaths Are on the Rise B. Highway Deaths Will Drop off
C. Measures to Handle Car Crashes D. Safety Advances in Cars Are Made
I have three kids and a great husband and I’m enjoying a career that I find challenging and fun．To the outside world，this feels like“Success．”But there is still a voice in my heart asking if this is who I truly am．Only in silence do I hear the self and wonder who that person might be．
So I booked a trip to find out．I travelled，for the first time，without my husband or kids．I went to Iceland with a friend，who shares an appreciation for wilderness and silence．
For six days，we were immersed(沉浸)in wild，raw scenery and real weather—a11 kinds of weather．Climbing a mountain against rain and returning to a tent for a simple meal reminds you how little you actually need．And how strong it feels to be uncomfortable sometimes．
I found silence in Iceland，and time to consider the me outside of career and the me out—side of kids as I shared stories with strangers．
When I stopped talking and just 1istened，I became more generous．I 1earned that choosing to be generous can create more space，more food and more warmth．
But I didn’t really gain any better appreciation of what I want from life or my job．I suspect the anxiety that drove me to seek silence in Iceland was losing sight of my ability to choose gratitude and joy，and to be present in the challenges I set in my career and my family．
I came home to noise，rush and love；with no less confusion on who I want to be． I know the answer isn’t waiting out there on the top of a mountain in Iceland．The answer is in front of me with every step on my own 1ife’s path，and in every choice I make．

Mauritius, an island nation, is working to get rid of fossil fuels by replace them with sugar cane stalks. An island has relied on imported gas as fuel for long but it points out which its main cash crop is providing a more economical choice.
Once a sugar cane stalk has squeezed, a pile of dry stalks remain. These leftovers are then burned to generate power, and it accounts for 14 percents of the island’s energy needs.
Sugar canes, the nation’s main cash crop, continues leading the charge towards a more environmental friendly future. Currently, four sugar companies run his own power station together with generating up to 60% of the island’s electricity. However, the carbon dioxide generated by the burning process is then used to add to soft drinks.
