   Younger adults who get either little sleep or a lot of it may see a greater increase in their waistlines (腰围)
over time, a study suggests.
    The study included 332 African-American and 775 Hispanic-American (西班牙裔美国人) men and women
aged 18 to 81. The researchers measured their abdominal(腹部的) fat, at the start of the study and again five
years later.
    Among the people younger than 40 in the research, the study found, those who said they slept for five hours or less each night gained more fat than those who averaged six or seven hours of sleep. Those who slept eight
hours or more in bed each night also showed a bigger fat gain-but it was not as much as that seen in "short
sleepers " .
    The findings, according to the lead researcher Dr Kristen, support the belief that sleep habits affect weight,
and health in general. " Sleep is an important part of your overall health-not just in whether you're tired during
the day," he said.
     As for why sleep time might affect abdominal-fat gain, there are several facts:
     People who get too little sleep may be too tired during the day to exercise, while those who spend a lot of
time in bed may spend less time being active, comparing to people who sleep fewer hours. Research also
suggests that sleep loss changes people's appetite-regulating hormones (胃口调节荷尔蒙)-which could, in
theory, make them overeat.
     What's more, depression, which is a feeling of sadness that makes people think there is no hope for the
future, could also be a reason. He also noted that it often affects people's sleep and has been linked to weight
gain.

A. Younger adults who sleep for five hours or less
B. People who sleep more than 8 hours every day
C. Younger adults who are from Africa or America
D. People who sleep about six or seven hours a day
2.  The underlined word "that" refers to____.
A. a fat gain
B. sleep habits
C. too little sleep
D. too much sleep
3. What can we leam from the passage?
A. The more we sleep, the more energetic we will be.

C. Those who are in sadness could easily get a bigger fat gain.
D. The African and Hispanic adults easily get a greater weight gain.

     Many earthquakes (地震) happen without warning, so it is important to know what to do wherever you
are during an earthquake. Here are some top tips on how to stay safe in an earthquake. 
    ◆ Keep a cool head. Worry may make bad decisions. Think about what you should do. The first several
seconds are important. 
    ◆ If you are indoors during an earthquake, hide under a heavy desk and protect your head. Stay away from
windows and anything that could fall on you.
    ◆ If you are in a crowded hall away from the door, don't rush to the exit. You will find too many people
trying to get out at the same time. Instead, hide under a desk or a table. Do not get into a lift during an
earthquake!
    ◆Stay in a safe area until you are sure it's OK to leave. Some aftershocks (余震) may follow an earthquake.
These are as dangerous as the earthquake. 
    ◆If you are at home and you smell gas, open a window and leave the building quickly.
    ◆ If you are outdoors, find a clear place away from buildings, trees, street lights and power lines.
    ◆If you are buried in debris (埋在废墟), you may make noises by knocking at the rocks. Shouting will use
