    Sunscreens (防晒霜) can offer protection from two types of ultraviolet (UV) rays (紫外线): UVB, which according to the Skin Cancer Foundation, are the chief cause of sunburn and play a key role in the development of skin cancer, and UVA, which get through the skin more deeply and are largely responsible for skin aging and wrinkling, as well as skin cancer risk. The SPF (防晒指数) measurement on sunscreens refers to the UVB protection level — and the number may not mean what you think it does. SPF 15 doesn't protect you from 15% of UVB rays, just as SPF 100 doesn't protect you from 100% of the rays. In fact, as you get into the higher numbered SPF sunscreens (think: 50 and above), the difference in UVB protection is actually pretty small.

    Theoretically, though the increase in UVB protection with a super-high SPF sunscreen may be not worth considering, it may help, and certainly can't hurt, to use it — that is, as long as you do so correctly. “The only downside is whether you're giving yourself a sense of false security,” Dr. Gohara says.

    Indeed, as Dr. Wang also pointed out, when people choose increased SPFs, they may actually feel so protected by the product that they finally ignore proper sun protection. “When people use really high SPF products, they tend not to reuse, they tend to stay out in the sun much longer, and they don't use other protective measures such as clothing and hats,” he says. Regardless of any increase in protection that a high SPF may or may not offer, one thing is certain: It doesn't give your body a free pass from sunburns, aging, or cancers, and it doesn't protect you from those things for any greater length of time than the lower SPF options. Both Dr. Wang and Dr. Gohara emphasized that, no matter what the SPF is, it's important to reapply your sunscreen every two hours.

    Eyesight plays a very important role in our daily life. Every waking moment, the eyes are working to see the world around us. Over forty percent of Americans worry about losing eyesight, but it's easy to include steps into our daily life to ensure healthy eyes. Here are five suggestions for a lifetime of healthy eyesight：

    Schedule yearly exams.{#blank#}1{#/blank#}Experts advise parents to bring babies 6 to 12 months of age to the doctor for a careful check. The good news is that millions of children now can have yearly eye exams and following treatment, including eye- glasses.

    Protect against UV rays. Long-term stay in the sun creates risk to your eyes. No matter what the season is, it's extremely important to wear sunglasses.{#blank#}2{#/blank#}

    Give your eyes a break. Two-thirds of Americans spend up to seven hours a day using computers or other digital products.{#blank#}3{#/blank#}Experts recommend that people practice the 20/20/20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away.

    {#blank#}4{#/blank#}As part of a healthy diet, eat more fruits and vegetables each day. Vitamins C and E help protect eyesight and promote eye health.

    Practice safe wear and care of contact lenses （隐形眼镜）. Many Americans use contact lenses to improve their eyesight.

    Environmental experts warn that our planet is drowning inplastic.

    The world's cities produce 2 billion tons of trash everyyear. By the year 2050 that number is expected to rise to 3 billion tons. TheWorld Bank estimates that the largest amount of trash today, about 44 percent,is plastic. But we often have to buy packaged goods. And often that packagingis made of plastic.

    Now, that may be changing. A new environmentally-friendlyshopping model was recently launched at the World Economic Forum in Davos,Switzerland. This shopping model, called Loop, aims to replace throwawaycontainers with reusable ones.

    Loop is the idea of Terra Cycle, an American-based recyclingcompany. Its chief, Tom Szaky told the Associated Press (AP) that "removingplastics from the ocean is not enough." He said the point is to get awayfrom single-use packages. Szaky said that Loop is the future of shopping. Butit comes from an idea of the past.

    He compared it to the "milkman model" of the 1950sin the United States. Back then, someone brought milk to your doorstep in glassbottles and then left with empty bottles. These could be cleaned and used again.The result is zero-waste.

    Jennifer Morgan from the environmental non-profitorganization Greenpeace also joined in the discussion about Loop at Davos. Shesaid that "Greenpeace welcomes the aim of the Loop Alliance to move awayfrom throwaway culture and disposability." But Morgan questioned whethercompanies worldwide are ready to change their business models.

    Loop is set to launch later this year in three eastern U.S.states, and also in Paris, France and some of the surrounding area. Then Loopplans to expand to the U.S. West Coast, Toronto, Canada and Britain by the endof this year or 2020.

Tips for healthy travel with children

    Children make up a small but important group of travellers. Their smaller bodies and developing immune(免疫) systems make their travel health needs important. {#blank#}1{#/blank#}.

    Vaccines(疫苗) for children

    In general, there is a higher risk for most vaccine-preventable diseases when travelling abroad. {#blank#}2{#/blank#}. If you are planning to travel, check whether your child's normal vaccine schedule needs to be changed to make sure that they are fully protected before travelling.

    Malaria(疟疾) and children

    {#blank#}3{#/blank#}. Children are particularly at risk of developing severe malaria. If you must travel with children to a malaria risk area, visit a doctor to determine if anti-malarial medication is recommended. If anti-malarial medication is allowed to take, keep them in child-proof containers and out of reach of children.

    Transportation risks

    Air travel is safe for healthy children. {#blank#}4{#/blank#}. Some airlines will not allow newborns to fly. Ear pain caused by changes in pressure during landing is more common in children than in adults. To lessen the pain, babies should bottle or breast feed. Older children can chew gum or be encouraged to swallow or yawn.

    Signs and symptoms(症状) of altitude sickness in children are often mistaken for other illnesses. A child with altitude sickness may throw up, hate to eat, or be anxious. Older children may also show headaches, or difficulty breathing. As it is difficult to tell if a child is developing altitude sickness and since altitude sickness can develop rapidly in children, you may travel to no higher than 2,500 m (8,200 feet).

A. High altitude sickness

B. Pack a travel health kit

C. Avoid taking children to areas with a risk of malaria

D. And these diseases tend to be more severe (严重的) in children than in adults

E. There are many facts to take into consideration when travelling with children

F. It may be difficult to give children anti-malaria medication because it tastes unpleasant

G. However, it is necessary that you wait until newborns are one to two weeks old before flying
