1．How much sleep do we need？It's a fundamental question about a basic human function we've been practicing for long，but there's still no simple answer．But whether you're a morning or evening person could be guided by your genes．That said，your sleeping pattern will change naturally with age，which is also reflected in the National Sleep Foundation recommendations：it suggests 14-17 hours of shut-eye a day for newborn babies and only 7-8 hours for over-65s．
   But scientists said it was about more than simple duration．Teens and people in their early 20s do want to go to bed later and get up later too，something researchers suggest might be to do with changing hormones（荷爾蒙）．"On average，there's about a two-hour difference in preferred sleep times of somebody in their late teens or early twenties to somebody in their late 50s or early 60s，" he said． "So asking a teenager to get up at 7 o'clock in the morning is the equivalent of asking a 55-year-old to get up at five in the morning．"
   At the end of the day，the best way to measure how much sleep you each need is to listen to your own body．Do you rely on an alarm clock to wake up？Do you take a longtime to feel awake？Are you dependent on coffee drinks to keep you focused during the day？Are you overly impulsive（沖動的）or do you find yourself running a lot of traffic lights，for instance？All these could be signs that you're not getting enough sleep．
   And that，we know today，is bad．The environment can affect your sleep preferences but your genes stay．Scientists said that the understanding of the importance of sleep was "one of the great achievements of modern neuroscience（神經(jīng)科學），" and that society was moving away from the all-nighter culture to respect the need for sleep．

（1）What's the writer's intention of writing the passage？

A．To report his research results．
B．To express the importance of sleep．
C．To list some sleeping patterns．
D．To persuade people to have enough sleep．
（2）What does the underlined word "that" in the last paragraph refer to？

A．Not getting enough sleep．
B．Listening to your own body．
C．Running a lot of traffic lights．
D．Not understanding of the importance of sleep．
（3）Which is the best title for the passage？

A．Sleeping Patterns
B．The Importance of Sleep
C．A Great Achievement of Neuroscience
D．Different People Need Different Amounts of Sleep

2．It appears to fit with most people's experience：how Christmas seems to come around quicker every year？Questionnaires by psychologists have shown almost everyone feels time is passing faster now compared to when they were half or a quarter as old.Most strikingly，lots of experiment have shown that，when older people are asked to guess how long the time is，or to'reproduce' the length of periods of time，they guess a shorter amount than younger people.
   In 1877，Paul Janet suggested the proportional theory，where a child of 10 feels a year as I 10 of his whole life while a man of 50 as 1/50，so the subjective sense of the 50-year-old man is that：these are insignificant periods of time which gallop.
   There are also biological theories.The speeding up of time is linked to how our metabolism （新陳代謝）gradually slows down as we grow olden Children's hearts beat faster than They breathe more quickly.With their blood flowing more quickly，their body clocks "cover" more time within the space of 24 hours than ours do as adults.On the other hand，older people are like clocks that run slower than normal，so that they lag behind，and cover less than 24 hours.
   In the 1930s，the psychologist Hudson Hoagland found body temperature causes different perceptions of time.Once，when he looked after his ill wife，he noticed she complained he'd been away for a long time even if only away for a few moments.Therefore，Hoagland tested her perception of time at different temperatures，finding the higher her temperature，the more time seemed to slow down for her，and that raising a person's body temperature can slow down his sense of time passing by up to 20%.
   Time doesn't necessarily have to speed up as we get older though.It depends on how live our lives，and how we relate to our experiences.

（1）What do the questionnaires and experiments find？

A．Time now is shorter than before.
B．Aging makes people think slowly.
C．The old feel time flies faster than the young.
D．The old value time more than before.
（2）What does the underlined word "gallop" in Paragraph 2 mean？

A．Fly swiftly.
B．Pause briefly.
C．Move slowly.
D．Pass stably.
（3）According to Hudson Hoagland，who may feel time go more slowly？

A．A kid with slower metabolism.
B．A child with low body temperature.
C．A grown-up feeling freezing.
D．An adult with a high fever.
（4）What is the best title for the passage？

A．How time flies!
B．To live a full life!
C．Why time passes at different speeds？
D．How to save more time？

3．An earthquake is one of the most common natural disasters.It may cause great damage.So it is wise to learn some simple safety tips to protect yourself or your family members.
    Fragile items like those made of glass are easily broken and should usually be placed on a lower surface，near the ground instead of placing them in the cupboards higher up.Never place them near your bed，sofas and other furniture where you would be sitting or lying down.When there is a strong movement，these pieces will fall on the floor directly and not on you.
   There is a strong chance of short circuits（短路）and fire during an earthquake.Make sure you turn off electrical connections and gas immediately when an earthquake happens.
   During an earthquake，lie beneath an object that is not easily damaged.Do not go near objects that could directly fall on you.Never use the elevator to go down.Stay inside until the shaking stops and it is safe to go outside.Research has shown that most injuries happen when people inside buildings try to go out.Use the staircases at all times.
   If you are outdoors，do not take shelter under a tree，streetlights，electric poles or tall buildings.If you are driving，stop your car and stay in a safe place.Do not park your car under a tree or any tall object.
   If trapped in debris（瓦礫堆），cover your mouth with a handkerchief or clothing.Tap on a pipe or the wall so that rescuers（營救人員）can find you.Use a whistle（哨子）if one is available.Never shout for help.Shouting can cause you to breathe in dangerous amounts of dust.Do not light a match because you may burn yourself.Do not move about or kick up dust.

（1）The purpose of the passage is to tell readers

.
A．what to do in earthquakes
