EDGEWOOD—Every morning at Dixie Heights High School，customers pour into a special experiment：the district's first coffee shop run mostly by students with special learning needs.
Well before classes start，students and teachers order Lattes，Cappuccinos and Hot Chocolates.Then，during the first period，teachers call in orders on their room phones，and students make deliveries.
By closing time at 9：20 a．m.，the shop usually sells 90 drinks.
“Whoever made the chi tea，Ms.Schatzman says it was good，” Christy McKinley，a second year student，announced recently，after hanging up with the teacher.
The shop is called the Dixie PIT，which stands for Power in Transition.Although some of the students are not disabled，many are，and the PIT helps them prepare for life after high school.
They learn not only how to run a coffee shop but also how to deal with their affairs.They keep a timecard and receive paychecks，which they keep in check registers.
Special－education teachers Kim Chevalier and Sue Casey introduced the Dixie PIT from a similar program at Kennesaw Mountain High School in Georgia.
Not that it was easy.Chevalier's first problem to overcome was product－related.Should schools be selling coffee？What about sugar content?
Kenton County Food Service Director Ginger Gray helped.She made sure all the drinks，which use non－fat milk，fell within nutrition guidelines.
The whole school has joined in to help.
Teachers agreed to give up their lounge(休息室) in the mornings.Art students painted the name of the shop on the wall.Business students designed the paychecks.The basketball team helped pay for cups.

Tips for Developing an Exercise Plan for Your Brain You know that eating a sensible diet and getting plenty of exercise help your body healthy and strong.But did you know that there are ways to make your brain healthier and smarter?
Studies show that when the brain is compelled to do something new，it creates new neural pathways(神经通路)．The more pathways you have，the faster you can think and the better memory
you will have.
Ten steps toward a smarter brain
Limit your TV time
Watching an average TV show requires very little brain power and brings the same result as neglecting physical exercise.Your brain will become weak just as your muscles do.If you watch TV，choose something educational and informative.
Travel
Traveling to a new country forces you to see and do things in a new way，providing stimulation(刺激) to the brain.
Learn a new language
Acquiring a new language involves different learning methods.Learning a language sharpens your brain and helps prevent memory problems in later years.
Master a new subject
Each week，select an animal，a bird or a fish，and read everything you can about it.Stretch (最大限度利用) your brain as you become an expert on the subject.
Use your non－dominant hand
If you are right－handed，use your left hand for everyday activities，or use your right hand if you are left－handed.Doing familiar things in a new way will cause your brain to create new neural networks.
Read often
As you read，take the time to look up people or places that aren't familiar.Reading expands your vocabulary if you search for words and definitions that you don't know.
Do puzzles
According to the Mayo Clinic，doing sudoku.and crossword puzzles keeps the brain sharp into your senior years.
Calculate while you shop
As you put things in your grocery cart，total everything in your head.See how much close you get to the actual total.
Play video games
Studies have found that certain video games force you to use critical decision－making skills and can even improve students' math scores.
Tweet！(推特，类似中国的微信)
Read messages from people who represent a wide range of interests.And some say that learning to express yourself in just 140 characters is a great brain challenge!
So get in the habit of challenging your brain，and make yourself smarter!

B．Develop an exercise plan.
C．Make your brain smarter.
D．Tips to make yourself healthier.

16．What does the underlined word “compelled” in the second paragraph mean?
A．requested B．allowed
C．completed D．forced
答案 D
解析词义猜测题。

根据下文内容可知，做一些具有挑战性的事情可以让脑子聪明。

B．Doing sudoku and crossword puzzles may make you confused.

How to be Emotionally Healthy
Think positively.It's amazing how much power our minds have over everything in our lives.A simple positive twist on a situation can turn an obstacle into an opportunity.To start this difficult step，focus on gratitude.When you start thinking about the bad thing swirling around you，stop.Cut it out.Think of two things you're grateful for.__18__
Be satisfied.This doesn't mean “ be content with your life”—it sort of means “satisfy yourself”．If you're on a diet，allow yourself a (small) bit of what you're craving.If watching The Golden Girls for three hours on a Friday night sounds like heaven，do it.__19__ Manage stress.This one is huge.__20__ Our homes get cluttered，our minds get cluttered，
and our relationships get strained.Set five minutes aside for yourself and think about your stress levels.A very healthy way of managing stress is doing yoga.
Take a break. This is similar to the “Be satisfied” step；you need to do what's right for you sometimes，regardless of what the world seems to be demanding.Without feeling guilty，take that well－known Kit Kat Bar.Spend a night in.Take a morning off.__21__ __22__ Even if you master every other aspect of health，you won't feel complete if you're suffering from inner confusion.Everyone needs a pick－me－up sometimes，and there are many small things that you can do to feel better about yourself.If the problem extends deeper，you may need to learn to cope with emotional pain or even depression.
A．Find emotional balance.
B．You'll be twice as energized when you get back to it.
C．Attack a few small things to get you going.
D．Whatever the small things are that make you happy，do them.
E．When stress takes over our lives，everything else falls apart.
F．Eventually，your mind will notice the pattern and stop the negativity.
G．Being emotionally healthy is easier to attain when you focus on the steps of your journey.
【语篇解读】本文是一篇说明文，主要介绍了如何在情绪上保持健康。
