Alice Moore is a teenager entrepreneur(创业者)，who in May 2015 set up her business AilieCandy．By the time she was 13，her company was worth millions of dollars with the invention of a super-sweet treat that could save kids' teeth，instead of destroying them．
It all began when Moore visited a bank with her dad．On the outing，she was offered a candy bar．However，her dad reminded her that sugary treats were bad for her teeth．But Moore was sick of missing out on candies．So she desired to get round the warning，“Why can't I make a healthy candy that's good for my teeth so that my parents can't say no to it？”With that in mind，Moore asked her dad if she could start her own candy company．He recommended that she do some research and talk to dentists about what a healthier candy would contain．
With her dad's permission，she spent the next two years researching online and conducting trials to get a recipe that was both tasty and tooth-friendly．She also approached dentists to learn more about teeth cleaning．Consequently，she succeeded in making a kind of candy only using natural sweeteners，which can reduce oral bacteria．
Moore then used her savings to get her business off the ground．Afterwards，she and her father secured their first business meeting with a supermarket owner，who finally agreed to sell Moore's product—CanCandy．
As CanCandy's success grows，so does Moore's credibility as a young entrepreneur．Moore is enthusiastic about the candy she created，and she's also positive about what the future might bring．She hopes that every kid can have a clean mouth and a broad smile．
Meanwhile，with her parents' help，Moore is generally able to live a normal teenage life．Although she founded her company early on in life，she wasn't driven primarily by profit．Moore wants to use her unique talent to help others find their smiles．She donates 10% of AilieCandy's profits to Big Smiles．With her talent and determination，it appears that the sky could be the limit for Alice Moore．
4．How did Moore react to her dad's warning
A．She argued with him．
B．She tried to find a way out．
C．She paid no attention．
D．She chose to consult dentists．
5．What is special about CanCandy
A．It is beneficial to dental health．
B．It is free of sweeteners．
C．It is sweeter than other candies．
D．It is produced to a dentists' recipe．
6．What does Moore expect from her business
A．To earn more money．
B．To help others find smiles．
C．To make herself stand out．
D．To beat other candy companies．
7．What can we learn from Alice Moore's story
A．Fame is a great thirst of the young．
B．A youth is to be regarded with respect．
C．Positive thinking and action result in success．
D．Success means getting personal desires satisfied．
Ⅳ．阅读七选五
Whether you're just starting your own business or thinking about beginning one，keeping costs down is important． 1 ．Here are some tips you can use to save money for your business．
Repurpose when possible
Before you spend money on a business，look around your home to see if you have something that could be repurposed to fill the need you have at work．For example，you could use some of your paint in the garage to make an old table and chairs look new．This is another form of recycling． 2 ．
Simplify your needs
3 ，and imagine what your business would look like without each one．If you don't need it，consider the cost savings and if it's worth doing without saving that money．If you're still designing your business plan，then build it with necessities only and add on as your business grows．
Give and take
Sharing advertising space on local posters or booths at trade shows can also help keep expenses down but your community recognition up． 4 ，such as sharing materials，transportation or building space．But make sure you engage with professionals you trust and get everything in writing so it's clear who is responsible for what．
5
Always keep your eyes and ears open to new opportunities not just for clients and work，but also for ways to improve on services you need as part of your business．If a new local business is offering good service at a reduced rate，support it and save money．Research each addition to your work until you find the best deal．Taking time to do this now will save money in the long run．
A．Never stop learning
B．Know your numbers
C．Partnerships can take many forms
D．Examine your expenses line by line
E．After all，every dollar saved will lead to a better future
F．Moreover，it keeps materials in circulation and your costs down
G．There are various free services and goods your business can make use of
