cycling because it is flat (平坦) and so is convenient for bikes. There are also plenty of places for bicycle
parking and most streets in the city centre have a bicycle path. Today some people call Amsterdam the
"City of Bicycles: because it"s convenient for people to cycle there."
In the 1960s, a group of cycling fans had an idea. They believed that it would be better for everybody
if cars weren"t allowed in the city centre and only bicycles were. They were hopeful that this would help to
save energy, reduce pollution and provide free public transport. The group painted hundreds of bicycles
white and placed them in lots of neighborhoods around Amsterdam for people to use. Anyone was allowed
to take them and use them for short journeys. When someone finished a journey they would leave the bike
there for someone else to use. The problem was that it didn"t work-thieves took all the bicycles within weeks!
However, more than thirty years later, the "white bike" is back in town this time with a computer chip to
record its every move! To take a bicycle, you have to put a special card inside. The new"white bike" is not
actually white but is an unusual design with bright colors. The bikes are parked at special parking place that
has enough room.
There is already less traffic in central Amsterdam, because both locals and tourists have used the white
bikes. Indeed, thanks to the good ideas of lots of people, like the cycling fans in the 1960, many people
around the world have been enjoying city centre streets without cars for many years.
B. Because there are so many bicycles there.
C. Because most streets in the city center have a bicycle path.
D. Because there are lots of places for bicycle parking.

exercise is sometimes called"warm-up exercise". Running is also a good exercise. If we cannot run fast, we
can jog. Jogging means running slowly. Before we run or jog, we must do warm-up exercises. And we should
not run or jog in busy streets. The air there is often dirty. Some people like weightlifting (举重) because it can
make their bodies strong. We also need to do some warm-up exercises before weightlifting.
B. Having no time to do exercises
C. Doing more exercises
