A MENTORING (导师制) program is giving life changing opportunities to Banbury youth.
Young Inspirations was founded two years ago to provide mentoring sessions for students and unemployed young adults aged 11 to 21.
Alex Goldberg, the program's founder, said; "We set up Young Inspirations because we wanted to give young people experiences which will potentially be life changing and broaden their outlook.
"We try to create work experience opportunities that will really make a difference to our youth. For example, we've secured internships (实习) with world-famous firms such as Honda.
"At a time of funding cutbacks where schools are finding it more and more difficult to offer this kind of mentoring, it is extremely important that these opportunities are available both to help youth with their school work and grades and to give them opportunities which may help shape their futures. " Kieran Hepburn, 14, is one of a group of Banbury youth who has benefited from the program so far. In October the Banbury School pupil was accompanied by Young Inspirations staff to Paris where he was an observer at the United Nations Educational, Scientific and Cultural Organization's (UNESCO) International Youth Forum (论坛).
The event was held for young people from around the world, to seek their views on how the future of youth and education should look. Kieran joined several hundred observers mostly in their 20s and was the only UK school pupil to attend the event. Kieran thinks the trip was a life changing experience. " Before we left I didn't quite know what to make of it but when we got there we didn't stop, it was amazing," he said, " We went to three or four hours of debates each day and then did something cultural each afternoon. "
The main theme of the forum was how youth can drive change in political and public life. It dealt with issues (问题) such as drug abuse, violence and unemployment.
Kieran said: " It has really helped me to improve my confidence and social skills as well as my school grades and I was voted most improved pupil at school in August. "
The Young Inspirations mentoring sessions take place each Friday in Banbury. For details visit www.younginspirations.com.

The English translations of the names of traditional Chinese dishes on menus(菜单) across the country have caused public discussion about the precision(准确) of the translations.
Since more and more foreigners come to China every day, many restaurants around China are providing English translations of their menus. They want to make it easier for foreigners to order Chinese dishes when they travel. Some restaurants also hope that the translations will increase foreigners’ knowledge of Chinese cuisine(烹饪).
But an article in China Youth Daily says the English menu translations haven’t live up to public expectation(期望). It argues most of the English names of Chinese dishes lack the cultural meaning and attraction of the dishes they describe. Instead, the translations only provide a list of each dish’s ingredients(配方), the article notes. For example, one English name of a Chinese dish appears as “stir-fried mutton slice with Chinese onion and green scallion(葱爆羊肉)”.
Because the English translation focuses only on the ingredients, it fails to describe the dish’s rich cultural meaning and charm(魅力). The dish’s beautiful Chinese name, “Fo Tiao Qiang(佛跳墙)”, has a story behind it. Buddhist monks (和尚) are required to eat vegetables only , but they can’t resist(忍住)the delicious dish. So they jump over the temple walls to get a taste of the dish.
The article suggests that translators provide more beautiful translations of the names of Chinese dishes. It also notes a more vivid(生动的) English translation is very important to provide international visitors with a better understanding of Chinese cuisine.
小题1:Why do many restaurants provide English translations of their menu ?
A.Because they want to show their ingredients in dishes.
B.Because the public expect them to do so.
C.Because Chinese dishes are popular.
D.Because it is convenient for foreigners to order food.
小题2:According to China Youth Daily, what is the main problem of the English menu translation?
A.They are too long to remember.
B.Many of them are not correct.
C.They lack cultural meaning and attraction.
D.They are difficult to learn.
小题3:What can we infer from the story of “Fo Tiao Qiang” dish?
A.Monks can jump high.
B.Monks lived a poor life.
C.Old China had little meat for people.
D.The dish attracted many people because it’s delicious.

More than half of the parents in the United States are helping, or have helped, support their adult children who have been hit by high unemployment and poor wages(工资), according to a new survey. It showed that present economic conditions are discouraging young adults from leaving home and forcing those who have already gone, so-called boomerang kids, to return.
“Parents are continuing their financial involvement longer than we expected,” said Ted Beck, president of National Endowment for Financial Education (NEFE).
About 60 percent of parents questioned in the survey said they’re helping their adult children who are no longer in school financially. Half are providing housing and nearly half are helping with living expenses.
For an increasing number of adult children, the situation is bad. Two-thirds of adult children, aged 18 to 39, who are not in school said they faced tougher financial pressures than previous generations, according to the survey. And nearly one-third of parents agreed that it was easier for them to find their financial feet than for their children.
Parents are helping their children out of genuine concern because they do not want to see them struggle. But Beck said that parents who make sacrifices(牺牲) to help their adult children should be careful about their own finances.
“If you are taking on extra debt or delaying(推迟) retirement to help your adult child, you could be making a mistake and putting your own financial future in danger,” Beck warned.
Boomerang children can also cause other problems for their parents. Thirty percent of parents said they had given up privacy since their adult children moved back home, while more than a quarter have taken on added debt, and seven percent have delayed retirement. But the survey also showed 42 percent of adult children living at home are helping with the cooking and cleaning.
小题1:According to the text, boomerang kids refer to ____.
A.married adult children
B.grown-ups living with parents
C.adult children independent and successful in life
D.young adults depending on parents for financial support
小题2:According to the survey, we can infer that _____.
A.about 30% of parents offer their adult children housing
B.one-third of adult children earn money more easily than their parents
C.two-thirds of adult children are faced with financial problems in school
D.about 50% of parents give money to their adult children to cover the daily cost
小题3:What is Ted Beck’s suggestion to the parents?
A.Asking their children to help with the housework.
B.Being careful when helping their children financially.
C.Leaving their children to struggle to live.
D.Putting off their time of retirement.
小题4:What would be the best title for the text?
A.Adult children are less independentB.Parents help support adult children
C.Bad conditions affect children a lotD.Adult children like living with parents

Most visitors come to the UK expecting the rain and weather for which the country is famous. However, when summer finally arrives, British people like nothing more than heading for the coast. Here are some of more famous places of interest that you could expect to visit on a trip to Britain. Black pool, in the northwest of England, is the most visited place in the UK. Each year around 6.5 to 7 million people come to enjoy the miles of sandy beaches, the 158m Black pool Tower and the 11km-long Golden Mile, where there are entertainments, pubs, ice rinks (溜冰场) and even a zoo. On the south coast of the country you can find Brighton. Until 1786, Brighton was a sleepy village. Then the future king, George IV, decided to build a house there, and now it has become a large, international centre. Apart from the beaches, Brighton is famous for its pier (码头). There are theatres, entertainments and restaurants there. Brighton is also fantastic for shopping. If you want to travel a little further, why not go to Corn-wall in the far southwest of the UK? South Cornwall offers miles of sandy beaches and beautiful scenery. The climate there is warmer than the rest of Britain, and you can even find palm trees. For a bit more excitement, go to North Cornwall. The scenery there is nicer, and the beaches are famous for their powerful waves. As a result, North Cornwall has become the home of British surfing. One word of warning though, if you are using the roads in the UK during holidays, you can expect long traffic jams on the motorways. It might be better to take the train.

E
When I was growing up, 16 was always a magical age, a symbol of maturity, responsibility and of course more independence and freedom.  I sat through the hours of Driver’s Ed classes eager to get out on the road. I couldn’t wait to get my driver’s license.
But it’s a different story for today’s teens. In January, the U.S. Department Transportation released 2012 data that showed only 30.7 percent of U.S. teens got their license at age 16, Twenty years before, that number was almost 45 percent.
There are numbers of reasons for the fall – off. The growing responsibilities like paying for insurance and high gas prices discourage teens from getting behind the wheel. Plus, many teens today are so busy with homework, endless hours of activities and part-time jobs, that finding the time for Driver’s Ed classes may be more difficult that ever.
In addition, many states have raised the driving age, or restricted when teens can drive and who they can have in the car. Parents may also be making their own personal restrictions until they feel their teens are responsible enough to drive safely.
Driving is part of the American culture, but it’s not the central focus like it was 25 years ago. They have so many other things to do now. One of the more interesting factors delaying teens driving might be the change of their social life. Today, teens need to look no further than Face book or other social networking sites to connect with their friends. There is simply less need, maybe less desire, to be able to grab the keys and go.
Michelle Wei got her license as a senior in high school because her digital social life made it easy no to drive. “If I couldn’t get a ride to see my friend who lives a town over,” the 19-year-old said, “I could talk on IM or Skype.”
Research has shown that these online relationships can lead to higher quality friendships, so it isn’t necessarily a bad thing. However, it’s important to find a balance. If old face-to-face friendships are good, why not drive to find them?
小题1:We can infer from the first paragraph that         .
A.Driver’s Ed classes allowed teens to know what maturity was
B.getting a driving license at 16 was a must for American teens
C.16 was considered an age when one could get his driver’s license
D.teens could drive on the road without taking Driver’s Ed classes
小题2:What does the passage mainly talk about?
A.Desire to drive on the road declines among American teens.
B.Getting a license costs much more than ever before.
C.Social networking sites are changing the life of American teens.
D.American teens are becoming more responsible than ever.
小题3:Michelle’s Wei’s example is used to explain ________.
A.why American teens are crazy about digital social life
B.what social networking websites are bringing to American teens
C.to what degree the Internet is affecting the American car culture
D.what the Internet does to help teens to get a driving license
小题4:The last paragraph is reminding the readers that        .
A.the Internet h as a bad effect on the teen’s social life
B.teens should keep a balance in choosing their lifestyle
C.actual contacts can be replaced by talking on line
D.face-to-face friendship is always the best choice

Driving a car is not just handing controls and judging speed and distance. It requires you to predict what other road users will do and get ready to react to something unexpected. When alcohol is consumed, it enters your bloodstream and acts as a depressant(抑制药), damaging eyesight, judgement and co-ordination(协调), slowing down reaction time and greatly increasing the risk of accidents. Even below the drink driving limit, driving will be affected.
Alcohol may take a few minutes to be absorbed into the bloodstream and start action on the brain. Absorption rate is increased when drinking on an empty stomach or when consuming drinks mixed with fruit juice. To get rid of alcohol from the body is a very slow process and it is not possible to speed it up with any measures like taking a shower or having a cup of tea or coffee.
The present Road Traffic Ordinance states clearly that the limit of alcohol concentration is:
·50 milligrams of alcohol per 100ml of blood; or
·22 micrograms of alcohol per 100ml of breath; or
·67 milligrams of alcohol per 100ml of urine(尿液).
Drivers who cause traffic accidents, or who commit a moving traffic offence or are being suspected of drink driving will be tested.
Any driver found drinking beyond the limit will be charged. The driver declared guilty may be fined a maximum of HK$25,000 and be sentenced to up to 3 years in prison and punished for 10 driving-offence points; or temporarily banned from driving.
The same punishment applies to failing to provide specimens(样本) for breath, blood or urine tests without good excuse.
Drink driving is a criminal offence. Be a responsible driver, think before you drink. For the safety of yourself and other road users, never drive after consuming alcohol.
小题1: The first paragraph is mainly about       .
A.the introduction of driving skills
B.the damage of drinking to your body
C.the effect of drinking on driving
D.the process of alcohol being absorbed
小题2: The underlined word “it” in the second paragraph refers to “       ”.
A.alcoholB.absorptionC.bloodD.process
小题3: Which of the following is TRUE according to the passage?
A.Drinking below the drink driving limit has no effect on driving.
B.Alcohol is taken in more quickly when drunk with fruit juice.
C.Having a cup of tea helps to get rid of alcohol from the body.
D.50 milligrams of alcohol per 100ml of breath is below the drink driving limit.

The early lack of exposure to science ,technology,engineering and mathematics (STEM) can be harmful to achieving gender (性别)balance in these fields. It begins when we are young and continues throughout our time in high school.
While at home,girls generally don’t get to experience the level of exposure or encouragement in STEM fields that their male counterparts do. It is often subtle ,but it’s the first hurdle that faces and confuses so many women. Boys ,on the other hand, get on their path ,and are encouraged to do so, generally earlier than girls. For example ,boys are more often given science sets as toys ,which spark an interest in these subjects.
In school 3 boys are often pushed to take the more challenging math and science classes. So if we want to attract the best and brightest minds into the fields that will advance us as a people ? a country,and a planet,we can no longer look to only half of the population. Young girls cannot possibly consider opportunities they do not know exist. If girls are not exposed to certain subject and career paths,they are highly unlikely to choose to follow them in college.
Our bias(偏见)toward girls9 either from families or from schools ,is so rooted in our culture that we often don’t even recognize it. Although the situation Has changed greatly in the past 20 or 30 years,there is still a sense that girls aren't as good at math 9 for instance 9 even though there is almost no evidence to support such a belief.
It is important that as a society we deal with gender stereotypes long before young people are faced with a decision to declare or choose a major in college. Without making efforts to break them, we are limiting the potentials of our youth,both male and female. Providing the necessary resources, exposure , and encouragement would help young women understand that their gender shouldnt determine the career path they choose, and that pursuing a STEM career does not make them less feminine.
小题1:According to the passage ? not many girls grow to enter STEM fields because______.
A.girls are not as good at STEM as boys
B.girls do not like to take science classes
C.girls get fewer chances to know about STEM
D.girls seldom survive the high pressure positions
小题2:The underlined word “it” in Para. 4 refers to______
A.our biasB.our cultureC.the situationD.a sense
小题3:The main purpose of the passage is to______.
A.show women’s potentials in STEM fields
B.praise women’s contributions to STEM fields
C.describe the present gender bias in STEM fields
D.call for more involvement of women in STEM fields

When I was 13, my bedroom walls were covered with posters of the Monkees and Beatles. I wrote fan letters and daydreamed about meeting the objects of my affections. I begged my  parents to attend every rock concert and watch every TV show featuring my favorite celebrities; my friends and I discussed for hours all the things we would say and do when we met our favourite movie stars and pop singers. I drove my mother crazy ! But after a few years, my obsession stars faded as I matured and gained the confidence to socialize with “real” boys.
In the 35 years since I was a teenager, celebrity worship (崇拜) has increased among teens due to the explosion of television celebrity gossip shows, and instant access to celebrity news on the Internet. It’s no wonder that many teens are obsessed with stars when news programs are often filled with entertainment stories and the lives of celebrities.
Celebrity worship syndrome (综合征) is now considered a personality disorder. While it is normal for teenagers to follow the lives of their favorite stars, parents should try to monitor everything their child finds interesting. Parents should take action if they suspect a teen is too obsessed with celebrities and showing little interest in school or withdrawing from the family.  When teens talk a lot about celebrities and view them as just means of entertainment, this is considered normal celebrity worship. However, when a teenager is obsessed with a star and  often expresses a desire to have a close personal relationship with a celebrity or feels they have a special connection to a star, this may be the time for concern. Recent studies have shown that teens who develop an unhealthy obsession with celebrities often suffer from low self confidence and depression. Teens who are overly obsessed with stars often have damaged relationships with their parents.
小题1:The first paragraph is intended to tell us________.
A.parents needn’t worry about celebrity worship
B.celebrity worship can cause serious problems
C.it’s normal for a teen to have celebrity worship
D.celebrity worship only exists among teens
小题2:We can learn from the second paragraph that________.
A.the media greatly contributes to celebrity worship today
B.the author is surprised at celebrity worship
C.teens today are not so obsessed with celebrities
D.celebrities expose their lives too much
小题3:Parents should become concerned when their children________.
A.talk a lot about celebrities with others
B.put up celebrity posters in their bedrooms
C.ask to go to their favourite star’s concert
D.desire a close personal relationship with their favorite star
小题4:The last paragraph implies that________.
A.parents should not care too much about a child’s celebrity worship
B.celebrity worship syndrome can be a serious problem if left overlooked
C.children can normally get out of celebrity worship when they are older
D.children with celebrity worship usually have high opinion of themselves
小题5:What is most likely to be talked about in the paragraph following the passage?
A.The harm of celebrity worship syndrome.
B.More signs of celebrity worship syndrome.
C.What to do with children’s celebrity worship syndrome.
D.Who will suffer most from celebrity worship syndrome.
