If you have a valid driver’s licence from your home country，you will be able to use the licence for a short period of time in Canada，though this will depend on your individual province and governmental laws. If you plan to use your foreign licence，the best thing to do is get an International Driving Permit (IDP) in your home country before travelling to Canada.An IDP will give you a translation of your licence in French and English. 38 ☆The process of getting a driver’s licence in Canada •It will depend on the province or community in which you live and on your driving background. •You may need to pass a written examination on the rules of the road (study guides are available) and one or two driving tests. •You may choose to pay for driving lessons to prepare for the driving tests (you can search online for lessons). 39 •Once you have a licence，it will have to be renewed periodically (see the expiry date on your licence). •See the transportation department in your province or territory for more information on driver’s licences，exams and driving lessons. ☆Car insurance It is illegal to drive a car without insurance in Canada，so if you own a car，you must ensure that you are covered by a reputable insurance company. 40 ☆Driving laws in Canada Driving laws are strictly reinforced in Canada and breaking the law can be costly and filled with punishments.It is recommended that you research and follow the rules of your particular province in Canada as some of the laws may differ. ☆Safety As Canada’s weather can be unpredictable and dangerous，it is recommended that you become familiar with safety standards and rules related to driving in winter. 41 1.If you’re qualified for your home driving，what can you do in Canada? A.You can always drive in some provinces. B.You can drive within a limited period. C.You needn’t transform it into IDP.

According to the guideline，which came out on June 6th，any enterprise，organization and individuals should be stopped from providing inking services.The guideline also prohibits “encouraging or forcing” children into getting tattoos，while encouraging parents to advise their children against getting tattooed. 语篇解读　这是一篇议论文。文章主要介绍了国务院未成年人保护工作领导小组办公室印发《未成年人文身治理工作办法》的消息以及人们对此的看法。 45 “All agencies that provide tattooing services should clearly display signs refusing minors，and ask customers to show their IDs if it’s hard to judge their age based on their appearance，” the guideline said. Tattoo culture has gained popularity especially among the country’s youth in recent years.They regard it as a form of fashion and self expression.However，tattoos haven’t been widely accepted in the society and they might have a bad influence on people in some situations. 46 Amanla，a tattoo artist in the southwestern Yunnan Province，said he agreed with the ban.He said，“Protection is necessary.But more deeply，it’s also disrespectful for people to do something merely to be cool without knowing what they really want or understanding the pattern being drawn on their body.” In recent years，several regions have issued local regulations banning tattoo services for children.In June of last year，a court in the eastern Jiangsu Province ordered a tattoo shop to stop tattooing minors after being accused of using ink containing harmful pigments(色素). 47 Yuan Ningning，a legal advisor specializing in family education law，said that the working guideline has cleared up the responsibilities between different regulators and called for more education and specific punishments. “The central government has already formed a consensus(共识)，” Yuan said.“But it takes a learning process among the local authorities for the guideline to be effective.That’s the first and a very crucial step.” 48 4.What should the tattoo shops do according to the regulation? A.Refuse to serve the minors. B.Offer quality service for teenagers. C.Ask the minors’ parents for advice.

B.Tattooing for minors must be punished. C.We should learn about tattoos before getting one. D.It is not easy for the regulation to be put into practice. √ 推理判断题。根据第五段中Amanla说的话可知，Amanla认为有时人们不知道文在自己身上的图案的意思而只追求“酷”是无礼的。由此推知，Amanla会赞同在文身之前对文身进行了解。故选C项。 解析 51 7.What can be inferred about the guideline? A.Those who break the rules will be punished. B.It has got wide recognition among the public. C.Educators play a key role in carrying out the rules. D.It is a long way for the guideline to make a difference. √ 推理判断题。根据最后一段第二句可知，这个条例要产生效果还有很长的一段路要走。故选D项。 解析 52 How do we slow down and eat more deliberately？And what are some techniques we can use to eat at a healthy pace？ Ⅱ.七选五 语篇解读　本文是一篇说明文，主要讲述了如何在吃饭时以健康的速度有意识地进食。 53 1 That’s when you use your senses to enjoy the food and notice how it makes you feel.
