    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.

    There are many fun, free activities that you can do as a family. All that is required is a bit of imagination and some time set aside for fun. And the best part is that these are the kind of memories a child will remember for a lifetime.

Family game night

    Find out any of the games that are already around the house. Kids often get computer games for Christmas or birthdays, and would love to have a chance to play with their family. Or, make up some games of your own. “Charades” is a fun game to play that will challenge a child to use his/her imagination. Divide the family into teams and let each team come up with words that the other has to act out.

Family art time

    Pick some time for the family to sit down and come up with their own masterpiece. It doesn't need to be just a drawing -- take some old magazines sitting around the house, let the kids cut out pictures and paste them into their own montage. Or, use items from nature. Let them use leaves, pine cones, twigs and whatever else they can find to create something from their imaginations.

Family Picnic

    Taking the family for a picnic is a great way for some fun that doesn't cost any money. If the weather is nice, take them to a park or playground and let the kids have a day of playing. Or, if it is the middle of winter and a foot of snow is on the ground, set up a picnic in the living room.

Family Field Trip

    A family field trip doesn't have to cost a dime. Ask a nearby farm if it would be alright to bring your kids out for a tour and to see some of the animals. Or take them to a park and make a scavenger hunt where they need to find certain items from nature. Ask a local business if you could bring the family for a tour to see how things work -- you might be surprised at the number of people who would be thrilled to share what they do with others, and it could be an interesting lesson for the kids.

根据短文内容,  从短文后的选项中选出能填入空白处的最佳选项,  选项中有两项为多余选项。

    Many people think of guys as being carefree when it comes to their appearance. But in fact, a lot of guys spend plenty of time in front of the mirror. {#blank#}1{#/blank#}.

    Body image is a person's opinions and feelings about his or her own body and physical appearance. {#blank#}2{#/blank#}. You appreciate your body for its capabilities and accept its imperfections.

    So, what can you do to develop a positive body image? Here are some ideas:

    Recognize your strengths. Different body types are good for different things. What does your body do well? Maybe your speed, strength, or coordination makes you better than others at a certain sport. That may be basketball, table tennis, mountain biking, dancing, or even running. Or perhaps you have non-sports skills, like drawing, painting, singing, playing a musical instrument, writing, or acting. {#blank#}3{#/blank#}.

    Exercise regularly. Exercise can help you look good and feel good about yourself. Good physiques (体形) don't just happen. {#blank#}4{#/blank#}. A healthy habit can be as simple as exercising 20 minutes to one hour three days a week. Working out can also lift your spirits.

    Respect your body. Practicing good habits — regular showering; taking care of your teeth, hair, and skin; wearing clean clothes, and so on — can help you build a positive body image.

    {#blank#}5{#/blank#}. Your body is just one part of who you are. Your talent for comedy, a quick wit (智慧), and all the other things make you unique. So try not to let small imperfections take over.

A. Be yourself.

B. Just explore talents that you feel good about.

C. Use this as an opportunity to discover what you're good at.

D. They care just as much as girls do about their body image.

E. They take hard work, regular workouts, and a healthy diet.

F. The good news is that self-image and body image can be changed.

G. Having a positive body image means feeling satisfied with the way you look.

    Amazon is breaking into physical retail(零售) in a new way. The online retail giant revealed a new kind of physical store concept in a video published on Monday.

    The store, called Amazon Go, doesn't work like a typical Walmart or supermarket. Instead, it's designed so that shoppers will use an app, also called Amazon Go, to automatically add the products that they plan to buy to a digital shopping cart by scanning a QR code. They can then walk out of the building without waiting in a checkout line because Amazon will charge their Amazon account and send them a receipt(收据).

    The first Amazon Go store is located in Seattle, where Amazon is headquartered. For years, there have been rumors the e­commerce company would expand its dominance(主导地位) from digital to physical shopping. Amazon began experimenting with physical bookstores a year ago, but Amazon Go may mark its boldest(大胆的) bet on physical ones yet. By removing much of the staff needed to operate a store, Amazon keeps costs lower than traditional competitors. It's also in a strong position to bring together data on its customers' shopping habits online and offline to make better suggestions in all situations.

    However, the company could be thought of as being a threat to some of the 3.4 million Americans who work as cashiers, according to the Bureau of Labor Statistics. And Donald Trump repeatedly criticized Amazon and its founder Jeff Bezos, “He's using the Washington Post for power so that the politicians in Washington don't tax Amazon like they should be taxed.”

    “Four years ago we asked ourselves: what if we could create a shopping experience with no lines and no checkout? Could we push the boundaries of computer vision and machine learning to create a store where customers could simply take what they want and go?” The company says on an informational page about Amazon Go. For now, Amazon is starting slow. The Amazon Go is only open to Amazon employees in our Beta program, and is scheduled to open to the public in 2017.

    Today's workplace is unique in history.Never before have we seen people working together who represent such different backgrounds and experiences.This difference of age,race,gender,and work style makes it very difficult to organize and run a company.

    As a result,companies are looking for individuals who can manage a wide range of employees effectively. Increasingly,managers are discovering that age differences among workers are a major cause of concern.

    This has been an important realization.The management difficulties and challenges have led some experts to study intergenerational differences for an understanding of problems in the workplace.What they have discovered is interesting and may provide ways of improving working conditions in companies that employ individuals from different generations.

    The first thing to realize,they say,is that differences of opinion about the importance of work and how to get work done are not a coincidence.That is,it is not an accident that young employees will be different from older employees.In fact,if employers do not pay attention to these differences,it is possible that anger will build up between people and lead to difficulties in the company.

    Resentment(仇恨)between members of different generations,if not attended to(处理),can lead to extreme anger and unhappiness and even lasting enmity if people are not careful.That individuals from different generations should come to view each other as if they were from different sides of warring countries should not be surprising.

    It is natural for individuals from the same generation to form alliances(联盟),to come together for protection. Different generations represent different experiences in life,and these lead naturally to different opinions about oneself and one's approaches to work.

    If you were raised in a time of plenty,when products were readily available and relatively inexpensive,you would believe that prosperity is natural and expectable.If,on the other hand,you were raised in a time of scarcity,you would always be careful not to waste things for fear you would not have enough.You would make angry people who seem to believe that problems will always solve themselves.Such optimism in the face of difficulties would be a source of unhappiness between you and them.It is difficult,in such circumstances,to achieve a happy,agreeable atmosphere in the workplace.
