Sometimes successful health campaigns can have quite unexpected reactions．The years of warnings about skin cancer mean that Britons are happy to cover themselves in sunscreen or stay out of the sun altogether, but it also means that most of us are not getting enough vitamin D.

Scientists announced yesterday that Britons need to increase to three times the amount of vitamin D they get per day．They called on food producers to fortify(強化)their products with more of the vitamin and suggested people should consider taking supplements(補充物) to keep levels up．They also suggested getting out in the sun for short periods more often, but they warned against “sun bingeing”.

The government does not publish official advice on the amount of vitamin D people should take due to a lack of research, says Dr Birgit Teucher of the Institute for Food Research．But in the US, the government recommends 5 micrograms a day．By that count, Dr Birgit Teucher said that around 90% of Britons between 19 and 64 would be lacking in the vitamin because they only took around 3 micrograms a day.

Vitamin D is important for absorption of calcium(鈣)by the body, which is needed for healthy teeth and bones．A lack of it can lead to serious diseases in both children and adults．The vitamin can be found in some foods but it can also be obtained from chemicals in the skin reacting to sunlight．Dr Barbara Boucher said adults should get 5 to 25 micrograms a day．Shortage of vitamin D may be linked to diseases such as muscle weakness, high blood pressure and rickets(佝僂病).

Dr Birgit Teucher gave several reasons for the lack among Britons．Increasing numbers of office-based jobs mean a lack of exposure to the sun; and the rise of becoming overweight means that vitamin D—which is fat soluble(可溶解的)一is increasingly stored in body fat, where it cannot be accessed readily.

Professor Brian Wharton of the Institute of Child Health said that children in particular needed to have enough vitamin D to prevent rickets.

Professor Graham Bentham, an environmental scientist at the University of East Anglia, added that babies who were only breast-fed probably need to take supplements in case their mother was vitamin D lacking．Those drinking milk were likely to be OK, thanks to the fortification of the drink.

The scientists called on food producers to fortify milk, bread and breakfast nutrient to enable people to get their daily amount of the vitamin．Prof Graham Bentham added that 30 minutes of sun exposure to the face and forearms between April and October would be sufficient．Outside these months, the sun is not strong enough in Britain for the body to produce its own vitamin D.

But Prof Graham Bentham warned against spending too long in the sun．“Sun bingeing is well known to be dangerous,” he said．“In any case, vitamin D transformation in the skin switches off after a while so short frequent amounts are better for vitamin D formation.”

1.From Paragraphs l&2 we can infer that_________.

A． some health campaigns are very successful

B． people are lacking in various vitamins

C． Britons are advised not to get out in the sun

D． vitamin D can be obtained by staying in the sun

3.From the passage, we can conclude_________.

A． the babies who were only breast—fed certainly need to take vitamin D supplements

B． a large quantity of vitamin D stored in body fat is the primary reason for being overweight

C． the sunlight can produce adequate vitamin D that the body needs all year round

D． vitamin D is vital for the body to absorb calcium needed for healthy teeth and bones

4.The government doesn’t give official advice on the amount of vitamin D because_________.

A． they think it is harmful for health

B． they don’t want to be blamed

C． they aren’t confident of its function

D． they haven’t concrete proof

A．How inner beliefs can help

B．Why are habits so important

C．How to develop positive habits

D．Improve your life

E．You can do it

F．Action plan

The single most important factor that contributes to success is what you do every single day．It is as simple as that．Your habits will determine whether you are successful or not．If you have strong and healthy positive habits，it does not matter whether or not you fail today because you are guaranteed to succeed in the long run．

1._________________________________

Because you repeat the same actions and the same behaviors every single day，a single positive action will not change your life，but the same action repeated 1,000 times will have a significant impact on your life．For example，if you go to the gym one time，you won’t see a big difference in your life．However，if you go to the gym 1,000 times over a five year period，you will see a big difference in your body．The same principle applies to finance，health，relationships，work，career，and school．Simple positive actions repeated every single day will have a great impact on your life in the long run．

2._________________________________

There’s nothing easier than developing positive habits．You simply have to do every single day the action you want to make a habit．If you want to develop the habit of running，run almost every day．If you want to develop the habit of eating healthy，eat healthy every day．If you want to develop the habit of reading，read every day．Habits are created by repetition．The more you do an action，the easier it becomes in the long run．

3.________________________________

If you want to be successful in changing your habits，you should think about changing your inner beliefs about your habits．For example，your old belief was: “I love cigarette because it makes me feel good and relaxed．I need cigarette to be happy and relaxed．”If you keep this belief，you won’t be able to keep your resolution to stop smoking for very long．Instead，you should adopt this new belief: “I love yoga because it makes me feel good and relaxed．Cigarette is poisonous and destroys my body．Yoga makes me happy．” You should analyze your beliefs and make sure they won’t stop you from changing your habits．The same is true when you try to form positive habits．If you want to start eating healthy food，here are some positive beliefs you should start thinking about: “Healthy food is very good for my health．It gives me a lot of energy and I feel very good．”

4.___________________________________

It’s now time for you to develop positive habits in your life and avoid your negative habits．Write down 3 positive habits that you would like to develop and 3 negative habits that you would like to get rid of．For each positive habit，write down exactly what actions you’re going to take every single day in order to develop the new habit．For each negative habit，write down exactly what actions you’re not going to take in the next weeks．Here are some positive habits that will lead to success: exercise，healthy food，reading，saving，studying，healthy relationships，hard work，etc．Here are some negative habits to get rid of: gambling，drug and alcohol abuse，overeating，shyness，etc．

5.___________________________________

Everybody can change．All it takes is courage and commitment．Decide right now to improve your life by changing your habits．Take action right now！Don’t be afraid．Yes，you will probably make mistakes along the way．But never forget that success is guaranteed for you if you have positive habits in your life．If you refuse to quit，success will be yours．
