閱讀理解。

     How could we tell time if there were no watches or clocks anywhere in the world? The sun was
probably the world's first  "clock" ,  except in the far north, where the Eskimos (愛斯基摩人) live.
There, it's dark most of the winter, and light most of the summer.  But in most of the world, people
have used the sun for a clock.  Even today, if you don't have a clock, you still know that when the sun
shines, it's day, and when it's dark,  it's night.  The sun can also tell you if it's morning, noon, or
afternoon.
     People who live near the sea can tell time from the tides.  In the daytime, for about six hours, the
water rises higher and higher on the   beach.  And then it goes down and down for about six hours. The
same   thing happens again at night.  There are two high tides and two low tides every 24 hours.
     Seamen on a ship learn how to tell time by looking at the moon and the stars. The whole sky is their
clock.
     In some places in the world the wind comes up at about the same time every day or changes
direction or stops blowing. In these places the wind can be the clock.
     A sand clock is an even better clock.  If you had fine dry sand in a glass shaped like the one in the
picture,  you would have what is called an hourglass. The sand in the hourglass goes from the top part
to the bottom part in exactly one hour. When the hourglass is turned over, the sand will take another
hour to go back again.

1. According to the passage, there are ______ ways to tell time besides the clock and watch.

A. 3
B. 4
C. 5
D. 7

2. The Eskimos in the far north can't use the sun for a clock because ______.

A.  they know very little about the sun
B.  the sun there never goes down in winter
C.  it's too cold for them to go out to watch the sun
D.  it has long dark winters and long light summers

3. The underlined word "tides" in the passage means ______.

A. 洋流
B. 潮汐
C. 海嘯
D. 波浪

4. In which page of a newspaper can you most probably read this passage?

A. News.
B. Science.
C. Business.
D. Advertisement.

5. What's the best title for the passage?
