Before she leaves home in San Francisco, California, Jennifer Schaefer, puts on long sleeves and a big hat she calls her “personal umbrella.” With her fair skin, red hair, memories of bad childhood sunburn, and a family history of skin cancer, Schaefer is painfully aware of the danger of exposure to ultraviolet (紫外线) radiation, which accounts for the vast majority of skin cancers.

So she finds it unbelievable how few people bother with sun safety, with most preferring sun worship to sun protection. “In our culture, it's almost funny to be too protected,” she says, highlighting the way her friends tease her when she puts on her bathing suit—a protective “rash guard top” and knee-length board shorts. “We're slowly starting to become aware of the long-term effects of the sun, but it's like global warming—people are not going to make serious changes until they feel a direct impact.”

That impact has helped push Australians, who are famous for sun loving, into changing their behavior. With its high solar ultraviolet levels and mostly fair-skinned population, Australia has the highest rate of skin cancer in the world. But after decades of increase, the melanoma(黑色瘤) rate began to stay at a steady level in the mid 1990s. The incidence of melanoma among young people is now falling, as national surveys show that most Australians-more than 70% of adults and 55% of adolescents—no longer prefer a tan (棕褐色).

A 2013 study shows that, in addition to Australia, a handful of countries—notably New Zealand, Canada, Israel, Norway, the Czech Republic(or women) and the United States (for white men) —have melanoma rates that are decreasing or stabilizing among young people.

Back in San Francisco, Jennifer Schaefer is doing her best to educate the next generation. Her eldest daughter automatically puts on a hat to go outside. “Habits really start in children—it is like brushing your teeth,” she says.

【小题1】By describing Schacfer's bathing suit, the author suggests that Schaefer ________.
A.does not mind the teasing by her friend
B.attaches great importance to sun protection
C.goes to extreme measures to avoid the sun
D.is more interested in surfing than sunbathing
【小题2】What do New Zealand and Canada have in common?
A.Sun protection programs are developing quickly.
B.Their citizens prefer to be pale rather than get tanned.
C.Skin cancer rates are not increasing among the young.
D.Women and white men have the lowest rates of melanoma.
【小题3】What's the purpose of the text?
A.To help individuals know how to make medical decisions.
B.To call for more research into ultraviolet radiation effect.
C.To draw the public's attention to ultraviolet radiation effect.
D.To honor a mother for her research into ultraviolet radiation

Effective Time Management Tips from Students

College years are something that many people remember mostly, like parties, meeting life-long friends and romantic adventures. Between those fun things, students have to find time for their actual studying. Many of them do it so skillfully that their professors wouldn’t even guess that they partied all night. 【小题1】 Here are some effective time management tips that can be used outside of college.

Use technologies

Many modern students can support the fact that technologies make studying easier and faster 【小题2】 You can save time on solving different problems as there are now many apps for that. Using technologies for work is also a must if you want to improve your productivity.

【小题3】

As you know, students have a strict class schedule. It helps them organize their days and be ready for each class. Having a schedule for work and life is also a good thing. If your day is planned by hours, it is easier to get every task done fast and effectively.

Learn something new all the time

【小题4】 They know that the more knowledge they possess, the easier it can be for them to get out of different situations. You need to be hungry for knowledge. Many people who graduate from college think that they’ve learned all the secrets of the universe and have nothing more to study. However, you still need to give some work to your brain. 【小题5】

A.Have a schedule
B.Learn a lot of things
C.Smart students complete their tasks faster.
D.Thus, you will do your work slower and waste a lot of time.

Many people spend weekends doing meaningless things, which is a complete waste of our life. However, successful people make the best use of their weekends differently. Here are some things they may choose to do.

【小题1】

Successful people don't go into the weekend with no plan. 【小题2】 It might be a little more loosely scheduled than a usual Tuesday, but with only so many hours in a week, successful people know they have to use all the free time they can get to finish tasks they need to.

Get up early.

Of course, it feels good to sleep in. However, it's actually quite refreshing (使人精力充沛的) to get up and move early on days when you don't have to get up early. 【小题3】 It will leave them feeling more refreshed than just wasting two or three hours lying in bed staring at the wall.

●Put the phone aside.

In today's busy world, most of us never truly leave work. Our phones are likely connected to our emails and Twitter accounts, meaning we may deal with a work-related task even after 5 p. m. 【小题4】 They go fishing or hiking or do something without their phones in their pockets.

●Follow hobbies.

【小题5】 They know they'll never get that time back. Even if their hobbies require hard work, they'll still be relaxed and comfortable while working on them if they're fond of them.

A.Make a plan.
B.Prepare for the week carefully.
C.But successful people need time to let work go.
D.The weekend is the perfect time to make up for it.
E.They plan their day out just as they would on any other day.
F.Successful people start their Saturday off by hitting the gym or reading a book.
G.Successful people use every minute of their free time to do something they love.

In the early 1980s, one of our neighbors asked my mom if she would make a few gift baskets for her to give as gifts for the holidays. My mom agreed and news of the unique gift baskets my mum was making spread like wildfire throughout the neighborhood. My mum was busy throughout the holiday season, so she asked a friend to help her. When the orders continued after the holiday season for baby gifts, birthday gifts and more, it occurred to them that maybe this job could be turned into a business and they did it.

My mum went into her business because she had a creative idea. She got orders and filled orders. But there was no purpose and no real strategy(策略). In 1991, my mum' s partner got into financial trouble and there was not enough money to support either my mum or her partner.

So if you are led by your creativity or enthusiasm, make sure you ask yourself what you want out of your business. If you don't set goals, how will you know what direction to go in? Do you want to create jobs and growth in the economy? Are you looking for a hobby? You can't keep scores if you don' t know what game you are playing.

After my mom's partner gave up, she had to abandon(抛弃) her business to support herself. She swore( 发誓) she would run a business again and do it differently the next time. However, there wasn't a "next time" for her. She passed away just after her 51st birthday. She never had someone tell her how important having a goal was. She never had an opportunity to be everything that she could be.

There are no right or wrong goals, only the ones that matter to you. Set them so that you can make progress and achieve success, whatever that may mean to you.
