   Passport Control

If you are arriving at London Heathrow Airport and are not transferring to another flight outside Britain or Northern Ireland, you must pass through Passport Control and Customs immediately after leaving your plane. If you are not British or a citizen of the European Community, you must fill out a special form before your passport is examined. This form is called a landing card and should be given to you during the flight to London.

After landing, follow the AKRIVALS signs. Make sure you are in the right channel when you reach Passport Control. There is one channel for holders of European Community passports, and a second channel marked "Other Passports".

Baggage Reclaim (行李领取) Area

After passing through Passport Control, follow the signs to the Baggage Reclaim Area. If you have luggage which was carried in the aircraft: along with other cargo, it will be delivered to you in the Baggage Reclaim Area. Look for the sign with your flight number. If you have only hand luggage, go directly through the Baggage Reclaim Area to Customs.

Customs

     All passengers must pass through Customs after Passport Control. There is a choice of two channels, Green and Red. If you have nothing to declare, go through the Green Channel. If you are not sure about your Duty Free allowances (免税额), or if you have something to declare, go through the Red Channel. Information about Duty Free allowances can be found on special notice-boards in the Baggage Reclaim Area. You should study this information carefully whether you are going through the Red Channel or not.

66%的人认为保健品业滥用孝心绑架消费者

本报记者：肖舒楠 实习生：刘雅琴

近年来，保健品市场鱼目混珠、夸大宣传等乱象丛生。上周，中国青年报社会调查中心通过民意中国网和搜狐新闻中心，对1891人进行的一项调查发现，47．0%的人表示对保健品的信任度降低，其中20．3%的人对保健品“完全不信任了”。另外，47．0%的人表示“一直对保健品有怀疑”。受访者中，71．5%的人购买过保健品。

保健品到底有没有用

武汉市市民吴先生坦言，自己一直对保健品的功效不大了解，“据说燕窝的营养价值不如鸡蛋，只是被贴上了营养圣品、保胎圣品、美容圣品等各式‘圣品标签’而已，让人看得眼花缭乱。”

调查发现，受访者对当前保健品的功效普遍持怀疑态度——51．0%的人感觉保健品“没什么作用”；21．5%的人担心保健品“反而有害”。另有36．0%的人确信保健品“有一些作用”，2．5%的人认为“作用很大”。

北京某高校临床医学专业研究生周爱琴认为，大多数人买保健品就是买个“安慰”和“放心”。周爱琴参加高考前，母亲曾为她买过保健品，据说“每天一瓶可以舒缓神经，增加记忆力”。她“吃了之后觉得轻松了许多”，但现在想来那只是一种心理作用，“因为当时身体其实没有明显变化。”调查中，30．5%的人觉得很多人购买保健品就是一种“安全感消费”。另有44．9%的人认为，保健品市场火热是因为人们对健康越来越重视，39．0%的人觉得很多人“生活习惯不健康，希望用保健品来弥补”。

中国保健协会保健食品委员会相关负责人提出，有针对性地服用保健品对身体健康有好处。保健品的一个明显优势是本身有营养，有的还具有医疗辅助作用。随着我国逐步进入老龄社会，保健品市场的繁荣还将继续。当前的问题是，如何进一步规范保健品市场。

76．6%的人呼吁加大对虚假宣传的惩罚力度

清华大学社会学系教授孙凤指出，如今保健品市场火热，很重要的原因是当前消费者对健康高度关注。很多商家正是抓住了这个契机，通过广告宣传等形式向消费者传递信号，比如“小孩子一定要补钙、补锌才能成长”，“成年人要补充各种维生素”等，以此来操纵消费者的购买观念。此外，保健品广告还会通过视觉上的冲击、明星的代言来诱导消费者。

保健品市场存在什么问题？调查中，87．5%的人首选“虚假和夸大宣传的情况较多”；66．0%的人认为，滥用“孝心”宣传的情况较多，有绑架消费者之嫌。

周爱琴认为，当前保健品宣传主打“孝心牌”的现象非常普遍。比如商家在广告和促销过程中将顾客买不买直接与孝不孝顺挂钩。一些保健品的广告上，还经常描述一个孝子拿着保健品送给父母，一家其乐融融的场面，这是一种变相的“滥用孝心”现象。

调查中，76．6%的人呼吁加大对虚假和夸大宣传的惩罚力度。

《保健品监督管理条例》一直未能出台

对于当前保健品市场存在的问题，73．3%的人直指“市场鱼龙混杂”。业内人士张先生告诉记者，要解决保健品市场鱼龙混杂的情况，关键在于完善制度。国家在2009年出台的新《食品安全法》虽然规定，保健食品的标签、说明书不得涉及疾病预防、治疗功能，产品的功能和成分必须与标签、说明书一致，但具体的《保健品监督管理条例》一直未能出台。保健品市场没有具体的行业规范，因此相关的监测和监管工作也无法展开。

张先生说，在一些发达国家，保健品类属于食品，与药品界限明晰。但我国很多东西都是药食同源的，比如枸杞子，既可以作为食材，也具有保健作用。所以在我国，保健品介于食物与药品之间，如果相关的界定和审批标准不够完善，会导致界限不明晰。这样一来，很多厂商会将保健品当作药品来宣传，且虚假宣传比较多，从而误导消费者；有的厂商则为节省成本，不走保健品的审批程序，但在售卖时极力宣传其保健功能。

中国保健协会相关负责人认为，政府应尽快出台《保健品监督管理条例》，同时保健品行业应建立安全诚信体系，确保产品质量和安全成为企业自觉自愿的行为；另外，国家还应加强营养保健知识的科普宣传和教育，让消费者树立“只吃对的，不吃贵的”的消费观念。

（选自《中国青年报》）

【小题1】下列对报告内容的分析和概括，不正确的两项是（     ）

A．规范保健品市场，是一个系统工程，政府应尽快出台《保健品监督管理条例》，保健品行业应建立安全诚信体系，确保产品质量和安全；消费者则要树立正确的消费观念。

B．清华大学社会学系教授孙凤认为，消费者对健康的过分关注导致当今保健品市场火热。很多商家正是抓住了这个契机，操纵了消费者的购买观念。

C．随着我国逐步进入老龄社会，保健品市场的繁荣还将继续。我们当前面临的问题是，如何进一步规范保健品市场。

D．我国很多东西都是药食同源的，既可以作为食材，也具有保健作用。在我国，一些相关的界定和审批标准不够完善，从而导致了那些介于食物与药品之间的保健品归属不好界定。

E．中国青年报社会调查中心通过民意中国网和搜狐新闻中心，对购买过保健品的1891人进行调查，结果，47．0%的人表示对保健品的信任度降低，20．3%的人对保健品“完全不信任了”。

Mr. Harris used to work in Dover, but then he changed his work, and he and his wife moved to another town. They did not have many friends there, but they soon met a lot of interesting people, and after a few weeks, they often went to dinner or to parties at other people’s houses.

Then Mrs. Harris said to her husband, “We’ve been to a lot of other people’s houses, and now we must invite them to our house, mustn’t we?”

“Yes, certainly,” answered her husband, “A big party will be the easiest thing, won’t it? Then we can start to invite people to dinner in small numbers next month.”

So Mrs. Harris said, “Yes, I’ll invite all our friends here to a big party on 5th December.”

“How many will that be?” Mr. Harris asked. “Don’t invite too many.”

Mrs. Harris was beginning to write the invitations when her husband saw that she was writing, “Party: 6:30 to 8:30 p.m.”

“That isn’t very nice, is it?” he said. “You’re telling our guests that they must go at 8:30.” So Mrs. Harris just wrote “Party: 6:30 p.m.”

A lot of guests came, and they all had a good time, so they did not go home at 8:30. In fact they were still there at mid-night when the door bell rang and a policeman arrived. He said, “You must stop making a noise, because someone has complained(抱怨).”

 Mr. Harris said he did not want to quarrel with the policeman, so everyone went home. They were sorry to have to go.

When I first started university, I remembered hearing about bone marrow(骨髓)donation during Freshman’s Week. Some students volunteers from a group called Marrow tried to convince me to attend an event so I could learn more about it. The word “bone” immediately made me think that donating would be a painful procedure, so I refused. Back then, there was no way I could have known three years later, I would be one of the many people that desperately needs a bone marrow donor to save their lives.

I am currently waiting to be matched with a donor and if I am lucky enough to find a good match, it will be this lovely stranger that saves my life. I received my cancer diagnosis in June. It is only at that time that I realized how ignorant I had been about the bone marrow donation process.

The process of donating stem cells is actually very simple. In 90% of cases, donors are asked to donate their blood stem cells, the other 10% will give their bone marrow. Lots of donors say that both these things are virtually pain free, and nothing to be scared about. Being a bone marrow donor should be something to be proud of, as every donor has an opportunity to save someone’s life!

At the moment I know that the doctors are busy searching for a match, I simply live every day in the hope that there will be a donor right for me. If I have an opportunity for life, I won’t waste it.

When I was a first year at university, I made the mistake of walking away from becoming a stem cell donor. Please don’t make the same mistake that I did. There are so many people out there, including myself, that need your help; and by undergoing a simple, pain-free procedure, you could have the chance to proudly say that you saved someone’s life.

   A. Because she could get nothing from it.

   B. Because she thought that donating would be painful.
