Scientists say they now have proof to support the old-fashioned advice that it’s best to sleep on a problem．They say sleep strengthens the memory and helps the brain organize the masses of information we receive each day．
The lead researcher Bob Stickgold at the Harvard Medical School said, “Sleep helps us draw rules from our experiences．It’s like knowing the difference between dogs and cats even if it’s hard to explain．”
The US research team studied how well students remembered connections between words and symbols, reports New Scientist．They compared how the students performed if they had had a sleep between seeing the words and having the test, and if they had not slept．They found that people were better able to remember lists of related words after a night’s sleep than after the same time spent awake during the day．They also found it easier to remember themes that the words had in common．But they forgot around one in four more themes if they had been awake．
Prof．John Groeger, of Survey University’s Sleep Research Centre, said, “People have been trying for years to find out what the purpose of sleep is, as we know that only certain parts of it have a restorative （促使康复的）value．”
“We form and store huge numbers of experiences in the head every day, and sleep seems to be the way the brain deals with them all．”

Visitors to Britain may find the best place to sample local culture is in a traditional pub．But these friendly pubs can be dangerous places of potential gaffes（失礼）for the newcomers．
A team of researchers have discovered some of the unknown customs of British pubs - starting with the difficulty of getting a drink．Most pubs have no waiters - you have to go to the bar to buy drinks．A group of Italian youths waiting 45 minutes before they realized they would have to fetch their own．This may sound inconvenient, but there is a hidden purpose．
Pub culture is designed to promote sociability（社交）in a society known for its reserve．Standing at the bar for service allows you to chat with others waiting to be served．The bar counter is possibly the only site in the British Isles in which friendly conversation with strangers is considered entirely suitable and really quite normal behavior．“If you haven’t been to a pub, you haven’t been to Britain．” This tip can be found in a booklet, Passport to the Pub: The Tourists’ Guide to Pub Etiquette, a customers’ rule of conduct for those wanting to sample “a central part of British life and culture”．
The trouble is that if you do not follow the local rules, the experience may fall flat．For example, if you are in a big group, it is best if only one or two people go to buy the drinks．Nothing annoys the regular customers and bar staff more than a group of strangers blocking all access to the bar while they chat and hesitate about what to order．
1.The underlined word “sample” in the first paragraph probably means “________”．
A．taste B．experience
C．test D．record

A．you won’t buy good local drinks
B．you may annoy the regular customers and bar staff
C．you may fail to feel the local culture
D．you might get into a dangerous place
4.What may be the best title for the passage?
A．Self-service Pubs in Britain
B．British Local Pubs: Special Chat Places

D．Manners in British Local Pubs
Car sharing is another way to drive green that’s gaining in popularity, especially in urban areas．People who may not drive every day but still want a car to run errands （差事）or drive on weekends benefit most from car sharing．Car sharing is usually run by a service like Zipcar, though there are non-profit （非营利的）and informal car sharing services．Members pay a monthly fee and have access to an entire fleet of cars when they need one．The cars are parked in fixed spots around the city, so members only need to make a reservation, and then go to the pickup spot．
Car sharing has major environmental benefits because it reduces the number of cars on the road．Members don’t drive just because they are in a car．They plan trips, and if they don’t need a car, they don’t use one．Still, a car is available to them if they need to make a big trip to the grocery store, pick someone up at the airport or if they want to go to the beach for the day．Members also benefit by having access to a car without any of the headaches of ownership．They usually don’t have to pay for the gas, insurance or maintenance （保养）, and the monthly membership fee is less than a typical car payment．So if you really want to go green but aren’t ready to totally give up a car yet, car sharing may be the way to go．
If you still need to get around, but want to go even greener than sharing a car, share a bus!

A man was on the side of the road hitchhiking（搭便车）on a very dark night in the middle of a terrible rainstorm, with no cars on the road．The storm was so strong that the man could hardly see a few feet ahead of him．Suddenly, he saw a car come towards him and stop．The man, without thinking about it, got in the car and closed the door and only then did he realize that there was nobody behind the steering wheel（方向盘）!
The car started to move very slowly．The man looked at the road and saw a curve （拐弯处）coming his way．Terrified, he started to pray, begging for his life．He had not come out of shock when, just before the car hit the curve, a hand suddenly appeared through the window and moved the wheel．The man, paralyzed with fear, watched how the hand appeared every time the car was drawing near a curve．Finally, although terrified, the man managed to open the door and jump out of the spooky car．Without looking back, the man ran through the storm all the way to the nearest town．In a state of complete horror, the man walked into a nearby bar and asked for two glasses of Scotch whisky．
Then, still shaking with fright, he started telling everybody in the bar about the horrible experience he just went through in the spooky car．Everyone in the bar listened in silence and became frightened, with hair standing on end, when they realized the man was telling the truth because he was crying and he was certainly not drunk!
About half an hour later, two other young men walked into the same bar and one said to the other, “Hey, there’s a stupid man who jumped into the car while we were pushing it!”

The town I live in is about to put cameras at all traffic lights to catch people who run red lights．It 36 me of how many people I’ve seen who take the yellow light as a 37 to go faster．I also can’t understand why people don’t move when the traffic light has turned green．Above all, there are those 38 situations in which someone doesn’t even 39 that the light turns red, and just keeps going．That is why so many 40 happen! All these situations make me 41__ the purpose of traffic lights．
42 , it’s even more frightening to imagine letting people make their own decisions at __43 crossroads．Do the biggest cars get to go first? Who decides who goes next? So I guess I do like the idea of a system to 44 traffic．And I’ll do my best to 45 the traffic rules: to go, to be cautious, and to stop when I’m 46 to．
It occurs to me that my 47 have done much the same for me 48 teaching me how to live．They have given me many 49 lights: to get along well with others, to listen and talk to them, to help others, and to 50 with joy and purpose．They have also given me some red lights 51 my life goes astray（误入歧途）: not to be greedy, to keep my temper, and to control my desires．And there 52 have been some yellow caution lights: to watch how much I drink, to keep control of my behavior, and to 53 school regularly and work hard．
If I obey these rules, my life will be as 54 as it can be．Just as I’m wise to pay attention to the traffic lights when I’m walking across the street, I’m wise to pay attention to the“ 55__ signals” given to me by my parents．
