“ Dining out”, or “ eating out ”,is a phrase people use in Britain when they eat in a restaurant or a pub. Eating out is more popular in Britain today than ever before.
However, eating out can be expensive. Restaurants are normally more expensive than pubs, though many pubs serve very good ,simple food. As British people don’t dine out every night of the week ,eating in a restaurant is often seen as a special occasion. When going for the first date, or if celebrating an anniversary or a birthday, many people like to go to a restaurant. People often eat in a restaurant before going to the cinema or the theatre.
As in all cultures, there are many rules of etiquette (禮節(jié))surrounding food and eating, and nowhere is this more pronounced than when eating in a smart restaurant. People are almost always expected to eat with a knife and fork and these should be held in the correct hand and used in the correct way. It is also impolite to have your elbows on the dining table when you are eating.
There’re many such “unspoken” rules — they are normally only important when eating in a very elegant and expensive restaurant, and vary slightly from restaurant to restaurant and place to place. A recent nationwide survey showed that there was a divide in manners between the north and south of Britain ---the “worst” manners were in Scotland and the northeast, and the “best” in Wales and the southeast! However, this survey was almost certainly conducted by someone in the southeast, so it may not be entirely fair.
Naturally, restaurants vary greatly in quality and price. However, almost all British cities have a vast range of food and cooking styles to choose from as well as traditional British food, from the very cheap to the very expensive — French, Italian, Indian, Greek, Thai, Japanese and many more. In fact, when asked what their favorite food is, many British people say an Indian curry (咖喱菜)rather than any other dish!
As well as dining in a restaurant ,when people are too tired to cook after work they often get a “takeaway”. This means they order from a takeaway or takeout restaurant by phone, then go to collect it and take it home to eat. Many takeout restaurants also deliver to your house. While you can normally find a takeout restaurant for almost any cuisine, the most popular are Italian, Indian and Chinese — and all you have to do is to open the door, pay and eat!
【小題1】 What can be concluded from the first two paragraphs?

A. The British spend more eating out than cooking at home.
B. The British pay great attention to eating in a restaurant.
C. The British often dine out when celebrating festivals.
D. People tend to eat in a restaurant after watching a movie.
【小題2】 The underlined word “pronounced" in Paragraph 3 probably means “_____
A. politeB.expensiveC.strangeD.obvious
【小題3】According to the passage, which of the following statements is true?
A. There exist great differences of rules in different restaurants.
B. People from Wales and southeast Britain are the most polite.
C. Your order in a takeout restaurant can be sent to your home.
D. Traditional British food is seldom served in British restaurants.
【小題4】 What does the passage mainly talk about?
A.Restaurant culture in Britain.
B.Table manners in Britain.
C.Different restaurants in Britain.
D.Traditional and foreign foods in Britain.

Aggressive pedestrians are in fact as dangerous as careless drivers. They cause traffic accidents, injury and death. These dangerous walkers can be seen in any big city all over the world. About 69% of last year’s pedestrian deaths in the US occurred in urban areas. They cross streets ignoring “DON’T WALK” signals, suddenly appear without warning from behind parked vehicles, walk slowly at crossroads with cell phones attached to heads, blocking traffic.
These pedestrians and drivers share a common disregard for the rules of the road, both for selfish reasons. The drivers believe in the power of their machines. If their machines can go faster, they believe they have the right to go faster. If their machines are bigger, they believe they have the right to push smaller vehicles aside. Aggressive pedestrians, on the other hand, believe in the primacy(首位) of the individual, the idea that they are first in any environment, under any circumstances, even when they are on foot in a roaring tide of steel and rubber.
Last year, an estimated 5,220 pedestrians died in traffic accidents. Some 69,000 pedestrians were injured. On average, that worked out to one pedestrian killed in a traffic crash every 101 minutes, and one injured every eight minutes.
The good news is that the accident rate is dropping. For example, the number of pedestrians killed last year was 24 percent less than the number killed in traffic accidents a decade earlier. The bad news is that the basic causes of pedestrian deaths remain pretty much the same----disregard for traffic signals, inattention and crossing roads under the influence of alcohol and drugs. Alcohol, in fact, was involved in 46 percent of the traffic accidents that resulted in pedestrian deaths. Of those, 31 percent of the pedestrians were found to be drunk.
The bottom line is that the pedestrians must do more to protect their lives as well as the lives of other road users. They can start by obeying traffic signals, using marked cross-walks and calling a cab when they’ve had too much to drink.
【小題1】The passage is mainly about _____.

A.what the traffic rules of the road about pedestrians were
B.why so many Americans were killed on roads last year
C.how aggressive pedestrians cause traffic accidents
D.who are to blame for pedestrian deaths, drunk drivers or the aggressive pedestrians
【小題2】What is the pedestrians’ selfish reason for traffic jams?
A.They believe individuals are always first.
B.They know all drivers are skilled and with great care.
C.They think traffic rules have nothing to do with them.
D.They guess all vehicles will slow down at crossroads.
【小題3】What was NOT the basic cause of pedestrian deaths in the US a decade ago?
A.Disregard for traffic signals
B.Paying no attention to surroundings.
C.Overspeeding driving.
D.Crossing roads drunk.
【小題4】What word can best describe the author’s attitude to the traffic accidents caused by pedestrians?
A.Excited.B.Cold.C.Unconnected. D.Concerned

It is often said that you cannot “teach an old dog new tricks”, but three New Zealand dogs have decided to prove otherwise by learning a skill --- driving a car!
What's even more impressive is that the three who have become skilled in just eight weeks are not special dogs that belong to some rich owners, but abandoned ones at New Zealand's SPCA.
To get their training started, 10-month old Porter, 18-month-old Monty and one-year-old Ginny were selected from a pool of seven potential candidates and moved to Animal Q, a talent agency that teaches animals tricks for movies and television shows.
The driving classes began with teaching the dogs some basic driving techniques like turning the steering wheels(方向盤(pán))and applying the brakes. After that the dogs practiced everything they had learnt behind the wheels of a motorized(裝上發(fā)動(dòng)機(jī)的)car. Then finally, it was time for the big test--- driving a real car!
Human cars are not really built for four-legged animals, so the car they drove was adjusted so that the dogs could sit comfortably and easily reach the steering wheel with their paws.
Though they all seemed to do very well, the real test came on Monday night when Monty, the best driver of the three, showed his great driving skill on live television.
Why would the SPCA go through so much trouble to highlight the skills of homeless dogs?  The reason is to show that adopting a dog from a shelter does not mean owners are getting a pet that is worse than one purchased from a keeper. The CEO of the SPCA is hoping that this unusual event will be enough to convince the residents of New Zealand to consider them, when searching for a pet.
We surely hope so, meanwhile we are almost certain that these three pioneers have at least landed their names in the Guinness World Records, creating a category that probably does not even exist today!
【小題1】Who do the three dogs belong to?

A.Some rich owners. B.Animal Q. C.A shelter. D.A zoo.
【小題2】The car the dogs drove was adjusted ______.
A.because is was too big for the dogs to drive
B.because it had no steering wheels and brakes
C.to ensure the dogs could sit comfortably and drive easily
D.to motorize the car and turn it to be a real one
【小題3】Which is the right order of the following events?
a. Teaching the dogs some basic driving techniques.
b. Selecting three dogs and moving them to Animal Q.
c. The dogs practiced everything they had learnt in a motorized car.
d. Choosing the best driver to show his great driving skill on live television.
e. Driving a real car.
A.a(chǎn)-b-c- d-e B.b-a-c-e-d C. b- d- a-c-e D.a(chǎn)- e- c-b-d
【小題4】Why does the SPCA decide to teach the three dogs to learn to drive a car?
A.To prove old dogs can learn new tricks.
B.To teach them performing tricks for movies and television shows.
C.To provide amusing performances for homeless children
D.To encourage people to adopt the abandoned dogs.
【小題5】What can we learn from the passage?
A.A new Guinness category for driving dogs will probably be created.
B.Abandoned dogs are much cleverer than house-kept ones.
C.All the dogs at New Zealand’s SPCA will soon be adopted.
D.New Zealand has the most homeless dogs among all countries

What does the word “home” mean to you? How do you say the word in French? In Spanish? In your language? Although people usually know what the word means, it often has no exact translation. It’s not surprising really, because the idea of home differs from country to country, and from person to person. A home is more than a roof and four walls. It’s the cooking, eating, talking, playing and family living that go on inside, which are important as well. And at home you usually feel safe and relaxed.
But it’s not just that homes look different in different countries, they also contain different things and reveal(顯示) different attitudes and needs. For example, in cold northern Europe, there’s a fire in the living room or kitchen and all the chairs face it. In the south, where the sun shines a lot and it’s more important to keep the heat out, there are small windows, cool stone floors and often no carpets. We asked some people about their homes.
How often do people move house in your country?
“In my country many people don’t stay in one place for a very long time. They often move every ten years or so.”
Cheryl, Boston, USA
What are typical features of homes in your country?
“In Britain, even in town there’s always a garden and sometimes a cellar(地下室). We have separate bedrooms and living rooms. But we don’t often have balconies (陽(yáng)臺(tái)). The weather isn’t warm enough!”
— Pat, Exeter, England

In the face of tragedy,you must of course let yourself feel: Cry without holding back, shake with fear, yell out in anger, accept and follow your feelings. This is part of the wise approach to tragedy: The Upward Path —the feeling of emotions, the acceptance of them, and the coupling of the emotional mind with wisdom. Along this path, you'll take the experience —no matter how sad or upsetting —as a learning event, just as a11 other points on your journey will prove to be. While tragic, you must recognize this is still a chance for all involved to grow. You should let both sadness and joy, fear and courage, dark and light fill your world, and learn to find your steady, calm center in the midst of the opposing forces. This is the Upward Path. Use the event as a chance to gain balance and discover wisdom —the wisdom of love and of letting go, of non-attachment and non-resistance, and using this experience to eventually help others in need of guidance.
Being able to relate to others who have also experienced tragedy and inspire in them hope — of recovery, and of moving forward —is perhaps the greatest gift you can receive from tragedy. Turn the negative into positive, the pain into connection. After you've taken appropriate time to be sad, to feel your own pain, you should make it your work,your goal, your purpose to connect with others who need help. Show them how you've experienced feelings, achieved
balance,and gained wisdom that you would never have otherwise had the chance to learn.
FEEL, but do not FEED on tragedy. Rather, let it inspire you to go beyond the person who you were before. With demise comes renewal, so let this loss be also your rebirth. No matter how hopeless it seems, no matter how difficult this becomes, you have the power to transform yourself into someone greater than you ever knew you could be.
【小題1】When following the Upward Path, the person facing tragedy should _______.

A.free his emotions
B.hold back his feelings
C.fill his world with positive ideas
D.give in to tragedy and all opposing forces
【小題2】According to the author,the greatest gift one gets from tragedy is being able to _______.
A.seek solutions from others
B.forgive others and move on
C.stay calm and resist change
D.understand and help others
【小題3】The purpose of the passage is to _______.
A.a(chǎn)nalyze the causes of tragedy
B.suggest a way of dealing with tragedy
C.tell people how to prevent tragedy
D.encourage people to build friendship after tragedy

Ceaseless technology. A punishing workweek. That to –do list that keeps multiplying. It is no wonder many of us find it difficult to have a sufficient amount of sleep. But will sleeping more on the weekend make up for hours of lost snoozing (小睡)? One sleep expert, W. Christopher Winter raised the question.
Sleeping binge
Getting eight hours of shut-eye each night is generally recommended, but many people don’t. As the week rolls from Monday to Friday, they accumulate a sleep debt. Spending a few extra hours in bed on a Saturday morning, people assume, will help them “ catch up” on lost sleep. They’re likely right, “ Nobody knows how long the horizon is, probably a few nights, but studies show that recovery sleep in the short term does work,” says Dr. Winter, a member of the American Academy of Sleep Medicine.
Sleep banking
Recent data suggests that banking sleep in advance of a long night can actually offset (補(bǔ)償) upcoming sleep deprivation(喪失). If you knew you were going to have to stay up all night on a particular day, for example, you could sleep for 10 hours a day for multiple days before the event, and be fine, Dr. Winter says. Just plan ahead.
Routine (慣例的)naps
A scheduled nap is healthier than catching up on or banking sleep. “ Because sleep extension can make you feel groggy (昏昏沉沉), I always recommend a short nap [if a person feels they need it ], at the same time, every day,” says Dr. Winter. He adds that 25 minutes is ideal. “ When you schedule a short nap, your body anticipates it and slows down, without falling into a deep dream sleep,” he says. That refreshing, scheduled break is better than an occasional weekend lie-in. “ The body likes routine,” he says, “ When it’s prepared, it works more efficiently.”
【小題1】From Monday to Friday, many people _________.

A.a(chǎn)ccumulate a sleep debtB.have no time to sleep
C.work hard to achieve their goalsD.have to stay up all nights
【小題2】Research shows that in the short term________.
A.a(chǎn) nap have no effect on work
B.a(chǎn) nap have effect on work
C.recovery sleep does work
D.recovery sleep doesn’t work
【小題3】If a soccer fan wants to stay up all night to watch two World Cup semi-finals, it may help if ________.
A.he keeps taking a nap for a week
B.he sleeps for 8 hours a day for days
C.he keeps sleeping for 2 days
D.he banks sleep in advance
【小題4】What is better than banking sleep, according to Dr. Winter?
A.Sleeping bingeB.Recovery sleep
C.Scheduled napsD.Sleep extension
【小題5】What would be the best title for the passage?
A.Sleep MattersB.Disadvantage of Sleeping Binge
C.Advantage of Routine NapsD.How to Sleep Well

Accidents happen almost every day. Some accidents are not serious and some are. We read about such accidents nearly every day in the newspapers. It is wrong for people to think that accidents take place only on the roads or highways, or even at work places. Home accidents are just as common. Because very few home accidents are reported, people come to think that there are few accidents which happen in homes.
There have been many cases where people fall to their deaths from high rise flats. Children often fall over while coming down the stairs. Old people may slip (滑跤) on wet floors if they are not careful.
Nowadays there are a lot of modern electrical appliances (電器) such as rice cookers which make life easy for the modern house wives. These appliances can kill if they are not used in the proper way. Gas stoves (煤氣灶) used for cooking are also dangerous if they are not properly used. They may cause burns or, in more serious cases, even fires.
But all such accidents can be stopped if we are careful and follow simple rules of safety. For example, it is unwise for people to try repairing their own electrical appliances if they do not know how to. It is safer to get them repaired by an electrician (電工).
【小題1】Accidents take place ____.

A.mostly in homes
B.mostly on roads and highways
C.mostly in factories
D.a(chǎn)lmost everywhere
【小題2】Which of the following accidents may NOT happen in homes?
A.People may fall to death from high buildings.
B.People may be knocked down by cars on the roads.
C.Gas stoves may cause burns or even fires.
D.People may be killed by an electrical appliance.

A.to avoid using electrical appliances
B.to repair their own electrical appliances
C.not to repair their own electrical appliances
