【推荐1】Sure, we’ve all heard that we should get more sleep. The realities of life often make it become “we should get more sleep later.”
·Move around.
Exercising before bed is a sure way to keep awake. That’s why you shouldn’t do it when you want to go to sleep, and it is also why hitting the gym, or even some fast push-ups can tell your body that it’s not time for bed. Being physically exhausted isn’t fun when you are trying to stay up late.
·Eat more protein.
Few people think about the fact that the brain and body use a lot more energy when we’re awake. If you are pulling an all-nighter, you’re going to need a lot more food than you are used to eating.

We spend most of our day sitting, whether at work, during a commute or at home. Some people say that sitting is the new smoking as it is bad for one's health in several ways.

It is essential to stay active, even during work, as one hour of intense training isn’t enough to make up for a whole day of sitting. According to studies, the risk of heart diseases increases by up to 117% when you spend prolonged sitting time. In the worst case, you may have a heart attack or stroke if you spend your whole day sitting for a long time.

【推荐3】Using natural and organic products for skincare is increasingly popular-and that includes suncream. Many websites, including Pinterest and Instagram, feature users' recipes for homemade suncream. Judging from the comment, the rise in interest for homemade suncream is because some people fear the chemicals in shop-bought suncream and believe that natural products mixed at home will be better at protecting them from the sun's harmful rays. The fear originates from recent news that some suncream elements seem to disturb hormones (荷尔蒙).
Many of the homemade suncream recipes contain elements like shea butter and cocoa butter as well as coconut and vitamin E oils. The sun protection factor (SPF) values for these elements, according to the authors of these recipes, are between four and six. These SPF values, if true, are not enough to protect the skin against the harmful effects of sunlight. Some recipes include carrot seed essential oil, which the authors claim to have an SPF of 35-40. But this is unlikely, given the small amount used in these recipes. The European Commission recommended SPF factor for moderate skin protection is 15-29 (and 30-50+ for high protection).
The sun's most harmful rays are ultraviolet (UV) radiation-notably UVB and UVA radiation. UVB has a shorter wavelength and doesn't go far into the skin, but it is very dangerous as it can change the DNA in skin cells and cause skin cancer. UVA has a longer wave- length and can go much deeper into the skin. UVA can cause harmful reactive oxygen molecules (分子)called “free radicals” to form. These molecules can damage fat, protein and DNA in the skin, thereby weakening the normal function of skin cells.
Shop-bought suncream contains approved UV-blocking molecules that block UVA and UVB rays. Zinc oxide (氧化锌)is one of these UV-blocking materials. It has been extensively tested to determine the most effective size for blocking harmful rays. It is not clear whether the zinc oxide powder recommended for the homemade recipes meets with the recommended size or proportion needed.

【推荐2】Born in 1902, Harry Beck was an English engineering draftsman (制图员) who brought about a small revolution in the early 1930s when he created a completely new map of the London Underground.
Before Beck’s design, early maps were usually drawn to a geographically accurate scale. Map designers simply placed the subway lines on standard maps of the city streets. These maps clearly showed the subway lines that reached the areas outside the centre of London, but they made it difficult to make out the busy lines that joined directly under central London.
In the 1930s, Beck came up with a solution that would not take the geographical accuracy into account. He created a map that was a scaled-down linear diagram of the subway lines. More a basic outline of the lines than a true-to-life map, it didn’t tell travelers about how far it actually was between two points. Beck’s map had a clean structure with coloured lines. His idea was to create the plainest guide to show travelers how to get from one station to another.
It’s not clear what inspired him to start the project; he wasn’t asked to do it, but likely developed his design in his free time, while between jobs. It was more a presentation of his being inventive, in seeing a problem and coming up with an answer to it, than a response to public demand.
His design was then presented to the London Passenger Transport Board, whose members refused to accept it, feeling that not showing relative distances between stations was silly and unreasonable. Still, after a time, in order to increase subway ridership and therefore earn more money, the Board decided to print a limited number of copies. Gradually, Peck’s map became a huge success.
For most of his life, Beck continued to make small improvements to the diagram, but he kept its basic designs and ideas. His clear diagrammatic method of mapping has been generally accepted and followed in the field of information design not only in London but also around the world.

【推荐3】Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.
Although there are many different types of food, some animals spend their lives eating only one type. The giant panda（大熊猫）eats only one particular type of bamboo（竹子）. Other animals eat only one type of food even when given the choice. A kind of white butterfly（蝴蝶）will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet（多样化饮食）. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.
