People who enjoy a dream-filled sleep are better at recalling information and making links between facts when waking. But recharging with a shallow (小睡) offers no such mental improvement, the research suggests. The results of the study added to the growing body of evidence that Rapid Eye Movement (REM) sleep is very important to the brain’s ability to form strong memories.
An average night's rest includes four or five spells of REM sleep, but these bursts tend to be lengthier towards the end of the night. This means adults getting less than the recommended seven to eight hours a night -- and therefore inadequate REM sleep -- may be damaging their mind's ability to memorize: Although REM sleep is not classified as a type of deep sleep, it is only reached after the brain has passed through deep sleep stages.
In the recent study, participants were shown groups of three words and asked to find another word that can be associated with all three words. They were tested once in the morning and then given the same task again in the afternoon. In between, some were allowed a nap with REM sleep, some a nap without REM sleep, while the others had a quiet rest period. The quiet rest and non-REM sleep groups didn't improve, but the REM sleep group improved on their morning performance by an average of almost 40 per cent. Dr Sara Mednick, a sleep researcher at the University of California who led the study, believes the formation of connections between previously unassociated information in the brain occurs during REM sleep.
It is believed that sleep acts as a sort of mental filing system, enabling the brain to sort relevant information from useless information. This process may take place as memories are removed hem one art of the brain to others.

Since the pre-historic times, man has had an urge to satisfy his needs. Be it hunger, shelter or search for a mate, he has always controlled the situations to his advantage. Probably this might be the reason why we humans are the most developed of all living species on the earth. As we climbed the steps of development, we somehow left behind common sense and logical thinking -- we forgot that we have stopped thinking ahead of time.
If you are hungry, what do you do? Get a piece of your favorite meal and stay quiet. Just like your stomach, even your mind is hungry. But it never lets you know, because you keep it busy thinking about your dream lover, favorite star and many such things. So it silently began to care about your needs and never let itself grow. When mind looses its freedom to grow, creativity gets a full stop. This might be the reason why we all sometimes think "What happens next?", "Why can't I think?" "Why am I always given the difficult problems?" Well, this is the result of using our brain for thinking of not-so-worthy things.
Hunger of the mind can be actually satisfied through reading. Now why reading and not watching TV? Because reading has been the most educative tool used by us right from the childhood. Just like that to develop other aspects of our life, we have to turn to reading. You have innumerable number of books in this world which will answer all your "How to?" questions. The interesting part of the book is stored in your mind as a seed. Now this seed is unknowingly used by you in your future to develop new ideas. The same seed, if used many times, can help you link and relate a lot of things, of which you would have never thought in your wildest dreams! This is nothing but creativity. More the number of books you read, your mind will open up like never before.

Cleveland has won the distinction of being the worst city in the United States, according to a new survey. The city has high unemployment, terrible weather, heavy taxes, and ordinary sports teams, all of which have pushed it to the No. 1 position in the Forbes.com list.
"Cleveland was the only city that fell in the bottom half of rankings in all nine categories. And it has been entitled with a less than endearing nickname: the Mistake by the lake," Forbes said on its website,
The economic downturn hit cities across the United States last year particularly in the mid-west section of the country. Crime and unemployment secured the No. 2 spot for Stockton, which held the top position in last year's ranking. Memphis got third place thanks to its violent crime rate and the number of officials who are guilty, while the poor auto industry drove the Michigan cities of Detroit and Flint into the top five.
"A lot of the cities that showed up on our list are going through hard times fight now, dealing with high unemployment, with declining producing bases. Many have experienced strong movement out of the city over the last 20 and 30 years."
Despite (尽管) its fine weather, Miami scored in the bottom 10 percent in commuting (上下班往返) time, and violent crime which sent it into sixth place.
"One of the biggest surprises is Miami. The good weather and no state income taxes blur some of the severe problems that Miami has related to crime as well as long commutes," Badenhausen added.
Florida was followed in the poor ranking by St Louis, Buffalo, Canton, Ohio and Chicago, which has the country's highest sales tax at 10.25 percent. New York, the nation's biggest city, is rich in culture but its lengthy commuting time and high income taxes pushed it into 16th place.
1.From the text we can learn that ______.
A．Cleveland has been entitled a lovely nickname
B．the economic downturn hit cities in the mid-east section
C．Miami scored in the bottom 10 percent in all nine categories
D．commuting time in New York is too long
2.What information can be inferred according to the text?
A．The number of officials who are guilty is large in Memphis.
B．Stockton got second place in last year's ranking.
C．High income taxes made New York get 16th place.
D．Ohio has the country's highest sales tax.
3.The word "blur" underlined in the last paragraph but one probably means ______.
A．make it possible B．make it unclear C．make if obvious D．make it important
4.Which of the following is the correct ranking order?
A．Cleveland, Detroit, Miami, Buffalo, Florida.
B．Stockton, Miami, Flint, Florida, Canton.
C．Cleveland, Stockton, Miami, Chicago, Florida.
D．Stockton, Detroit, Miami, Florida, St Louis.
Some plants get so hungry they eat flies, and even small frogs. What's more amazing is that these plants occur naturally (in special environments) in every state. In fact, they're found on every continent except Antarctica.
You've probably seen a Venus' flytrap -- a small plant, which grows 6 to 8 inches tall in a container. At the end of its stalks (茎) are leaves that act like traps (陷阱). Inside each trap is a lining of tiny hairs. When an insect lands on them, the traps suddenly shut. Over the course of a week or so, the plant feeds on its catch.
The Venus' flytrap is just one of more than 500 species of meat-eating plants, says Barry Meyers-Rice, the editor of the International Carnivorous Plant Society's Newsletter. He states although you might have read some science-fiction stories, no meat-eating plant does any danger to humans.
Barry says a plant is meat-eating, only if it does all four of the following: "attract, kill, digest, and absorb" some form of insects. Meat-eating plants look and act like other green plants -- well, most of the time.
All green plants make sugar to produce food. What makes meat-eating plants different is their special leaves, which need insects for one reason: nitrogen (氮). Nitrogen is a nutrient that they can't obtain any other way. Why?
Almost all green plants on our planet get nitrogen from the soil. Meat-eating plants can't. They live in places where nutrients are hard to get from the soil because of its acidity. So they've come to rely on getting nitrogen from insects and small animals. In fact, nutrient-rich soft is poisonous to meat-eating plants. Never fertilize (施肥) them! But don't worry, either, if they never seem to catch any insects. They can survive, but they'll grow very slowly.

A．is a small plant which grows in a container

A．meat-eating plants are found nowhere else except Antarctica

C．meat-eating plants endanger humans in science-fiction stories
D．the nutrient-poor soil is beneficial to meat-eating plants
3.Meat-eating plants grow very slowly, ______.
A．so you'd better fertilize them
B．probably because the supply of nitrogen is cut off
C．simply because they can't absorb nitrogen from the soil
D．and then they will die slowly

A．Meat-eating plants look and act like other green plants.
