deserts, so people can live and grow food. They are learning a lot about the deserts.  But more and more

Think about what you should do.  The first several minutes are important.
     If you are indoors cluring an earthquakc, quickly move to a safe place in the room such as under a
desk or table. Take care of your head. Stay away from windows and things that may fall and hurt you.

people trying to escape (逃跑) at the same time. Instead (相反), stay under a desk or table. Don't use
an elevator (电梯). You may not get out of it.
     Stay in a safe place until you are sure it's ()K to leave. Some aftershocks (余震) may follow an
earthquake. These are as darigerous as the earthquake.
     If you are in dcbris (废墟), try to  free your hands and legs. You may make noises by hitting stoncs.

     How to build energy into your mornings Here are a few things I've found helpful to become fully
alert (清醒的) from being asleep. Not only does speeding up this wake-up process save time, it makes
waking up less of a struggle.
     Light. Your body's natural clock is tuned to the amount of light. Turn on all the lights in your room
right after waking up. Getting bright lights can help trick your body into thinking it is time to get out of bed.
     Exercise. Put something physical right at the start of your morning. In the summer, I did a quick morning
run and found it helpful in shaking off any sleepiness. Considering the outside temperature hovers (持续)
around--- 20℃, I've stuck to doing a few pushups in my room. The exercise gets your heart pumping and
snaps you out of a groggy (摇摇晃晃的) state.
     The 10-minute rule. If you want to stick with a consistent wake-up time, practice the ten-minute rule.
This means you commit to staying awake for at least the next ten minutes. Once you get over that initial period,
the temptation to go back to bed is usually gone.
     Active work. Start your day with work that actively uses your mind. Creative activities like writing,
drawing, programming or designing work better than passive activities like reading. By focusing your mind
early you can stay focused and brush off any unwanted drowsiness (昏昏欲睡).
     Don't skip breakfast. Wake up early enough to get something to eat. Skipping meals throw your metabolism
out of balance, causing you to gain fat and lose energy. Skipping breakfast also means your blood sugar will
be low in the morning and energy levels down.
    Commit to a sleep schedule. The obvious solution to combat against sleepiness is to get more rest at night.
Carrying a sleep debt throughout the week with the hopes of paying it off on the weekend is a bad strategy.
Instead, compress your work into the morning hours so you can get the 6-8 hours you need each night.
    Turn up the volume. I've found listening to music or audio (音频的) books helpful in keeping myself awake
during the morning. Best of all, if you put on an audio book from your favorite speaker, you can get some
encouragement to start your day.

1. _______ tips are mentioned in this passage.

A. Six
B. Seven
C. Eight

2. Which will NOT happen in the passage if you always have skipping meals?

A. Your blood sugar will be low.
B. Your energy levels will be down.
C. You can be far away from fatness.

3. Which is right if you want to have a good energy? 

A. You can carry a sleep debt during the week and have good sleepiness on the weekend.
B.  Listening to music or audio books in an acceptable volume.
C. You'd rather stay in bed and read a book than writing, drawing and programming.

4. Which expression has the same meaning as the underlined phrase "brush off" in the passage?

A. Turn up.
B. Wake up.
C. Shake off.

5. What's the likely meaning of the underlined word "combat" in paragraph 7 in Chinese?
