Tricks to Learn from Super Sleepers
Do you want to sleep soundly each night and wake up energized the next day? Here’s a peek at some smart,surprising habits of great sleepers.
Exercise early.
Morning fitness class or gym time before work?Go ahead,give it a try.1.While experts aren’t exactly sure why,it could have something to do with morning exercise’s ability to help regulate the secretion(分泌物) of certain hormones involved in blood pressure management, which may lead to better sleep.
Eat light at night.
Desiring a midnight snack? If your stomach starts rumbling(发出咕噜声) before bed, try reaching for good-for-you foods that actually promote sleep, like walnuts, tart cherries, or Greek yogurt instead. 2.Eating too much of anything within a few hours of going to bed could suppress(抑制) your body’s ability to produce sleep-promoting melatonin.
Power down at night.
Smart phones, tablets, and laptops let you do everything from shopping to watching movies to working in bed.What they don’t let you do?Fall asleep. 3.In addition to reducing your blue light exposure,you’ll probably feel less stressed,which in itself can help you sleep better.
Keep their rooms chilly.
4.But being too warm can make it harder to have quality sleep, say experts at the National Sleep Foundation. Instead, they recommend keeping your bedroom at around 20℃,which research suggests is the most suitable temperature for great sleep.
5..
Consistency is key to healthy sleep.Though it’s tempting to stay up late,then get up early for work and sleep in on the weekend,doing so can cause damage to your body’s internal clock.Over time,that can make it harder to fall asleep,not to mention making it more unpleasant to wake up in the morning.
A.The idea of a comfortable bedroom and piles of soft, fuzzy blankets is very appealing.
B.Find ways to cope with stress.
C.Go to bed at the same time every night.
D.Still,try not to go overboard even with healthy stuff.
E.You don’t have to give up alcohol altogether in the name of better sleep.

When you’re a parent to a young child, you spend a lot of time talking about feelings: about having to share, about being disappointed because you may not have a cookie instead of broccoli(绿花椰菜), about the great injustice of a parent pressing the elevator button before the child has a chance to.
And in a parenting culture that’s increasingly concerned with centering children’s needs above all else, mothers and fathers have become skillful at talking about their kids’ feelings while masking their own. But new research suggests that parents who hide their negative emotions are doing their children, and themselves harm.
A study published this month says that when parents put on a faux-happy (假开心)face for their kids, they do damage to their own sense of wellbeing and authenticity.
“For the average parent the findings suggest when they attempt to hide their negative emotion expression and over express their positive emotions with their children, it actually comes at a cost: doing so may lead parents to feel worse themselves,” researcher Dr Emily Impett, says.
It makes sense that parents often fall back on amping up (扩大) the positivity for the sake of their children—there are a lot of things in the world we want to protect our kids from. But children are often smarter than we expect and are quite in tune with what the people closest to them—their parents—are feeling.
There was a time about a year or so ago, for example, when I received some bad news over the phone; I was home with my four-year-old and so I did my best to put on a brave face. She knew immediately something was wrong though, and was confused.
When I finally let a few tears out and explained that Mom heard something sad about a friend, she was, of course, just fine. My daughter patted my shoulder, gave me a hug, and went back to playing. She felt better that she was able to help me, and the moment made a lot more sense to her emotionally than a smiling mom holding back sobs. I was glad that I could feel sad momentarily and not have to work hard to hide that.
Relaying positive feelings to your children when you don’t feel them is a move the researchers called high cost—that it may seem like the most beneficial to your child at the time but that parents should find other ways of communicating emotions that “allow them to feel true to themselves”.
But this is also about children seeing the world in a more honest way. While we will want to protect our children from things that aren’t age-appropriate or harmful, it’s better to raise a generation of kids who understand that moms and dads are people too.

We all use money every day. It is essential because we can pay money for whatever we want.Money is recognized as banknotes and coins.
However,many years ago people couldn’ t go to the shop and buy what they wanted.They had to get what they wanted through the barter trade(实物交易).It was really difficult,for the barter often depended on coincidence of wants.For example,the seller of grain has to find a buyer who wants to buy grain and who also could offer something the seller wants to buy.And one more example,if a wheat farmer needs what a fruit farmer produces,a direct exchange is impossible because seasonal fruit would spoil before the grain harvest.The solution is to trade fruit for wheat indirectly through a third intermediate commodity(中间的商品),such as cattle,salt,shells,wine.However,commodity money had their disadvantages.For example,cattle,fur,precious stones couldn’ t be cut into smaller pieces and it was inconvenient to keep and transport them.Thus coins were invented.
The earliest known coins in the western world came from Lydia in about 650 B.C.Greek cities,the Great Persian Empire and Roman Empire quickly adopted the new useful technique of metal currency.And by the end of the 6th century,coinages were common throughout the region.However,coins as well as commodity money had many disadvantages.For instance,coins quickly show wear(磨损) and they usually have small value,so it’ s difficult to count large sums of coins.
At first,paper money was used in China in about 650 A.D.After then,it was used in Persia and Japan.In Europe,paper money was firstly produced in the Netherlands in the 16th century and in the USA in the 17th century.Paper money is worthless but symbolic.In other words,paper money is just a note.It has a purchasing power because the government announces it as money and citizens accept it universally.

C. They still had many disadvantages.
D. People didn’ t like the metal currency.
3.Paper money was used earlier in_______.
A. Rome B. Greece
C. the USA D. the Netherlands
4.What is the passage mainly about?
A. Function of money. B. History of money.

New research shows that kids from low-income families may be falling behind their peers because an important part of their brains is underdeveloped.
Researchers from MIT’ s McGovern Institute for Brain Research compared the brains of 12-and 13-year-olds from rich families with the brains of their peers from lower-income families. They found that one particular area of the brain—the neocortex(新皮质),which plays a key role in memory and learning ability—is thinner in children from lower-income households.
This is a crucial part of the brain for young students, who are often tested based on their ability to recall large chunks of information. Children who had a thinner neocortex performed poorly on standardized tests,researchers found.More than 90% of high-income students scored above average on a statewide math and English/Language Arts standardized test,compared with less than 60% of low-income students.Differences in cortical(脑皮层) thickness could account for almost half of the income-achievement gap in this sample,researchers wrote.
“Just as you would expect, there’ s a real cost not living in a supportive environment. We can see it not only in test scores,in educational attainment,but within the brains of these children,”says psychological scientist John Gabrieli,a professor of brain and cognitive sciences at MIT and one of the study’s authors.
Since a 2011 study published by Stanford University professor Sean Reardon found that the gap between standardized test scores of high-income and low-income students has grown by about 40% since the 1960s,there’ s been a lot of research aimed at finding links between income and achievement, rather than race alone. The MIT study found low-income children were equally likely to have a thinner neocortex,no matter their races.
Gabrieli and his co-authors can’ t say exactly why poor children’ s brains develop differently because there are too many possibilities to count.Their findings do,however,underline the importance of early intervention(干预) to ensure that low-income kids get the tools they need to succeed.
1.What’ s the function of the first paragraph?
A. To list some findings.
B. To give some advice.
C. To do some comparisons.
D. To show the main idea of the text.
2.What does the underlined word “crucial” in Paragraph 3 mean?
A. Special. B. Important.
C. Separate. D. Unknown.
3.What John Gabrieli says in Paragraph 4 mainly shows the importance of .
A. cognitive ability
B. educational attainment
C. having developed brains
D. living in supportive surroundings
4.What is the main idea of the passage?
A.Wealthy parents do better in raising children.
B.Differences exist between poor children and rich ones.
C.Poor children study harder due to their financial conditions.
D.Poor children have thinner neocortex than their wealthy peers.
