On the evening of September 26， 2019， the streets of Geneva in
Switzerland went dark. This usually happens when there is a problem with
the electricity， but this time the lights were turned off to allow people to go
outside and look at the stars. This is often impossible in a city because of light
pollution.
一

三
四
五
Light pollution is when light from streetlights or buildings makes the
night less dark. There are many reasons why this is a problem. Animals sleep
less because they think it is still daytime. Birds that fly to warmer countries in
the autumn need to see the moon and stars to find their way， but light
pollution makes this difficult. Insects and birds in cities often fly towards
lights at night， knock into buildings and die.

Light pollution is also bad for us. It can stop us sleeping and give us
headaches. Also， we don’t see the same sky that people in the past did. This
means we almost never see one of the greatest scenes in the world： the
millions of stars. Hundreds of thousands of people have never seen it in their
lives.
However， it is not difficult to do a few things to reduce light
pollution： we can all turn off lights when we don’t need them and we can
cover our windows. If there is less light pollution， we will once again be
able to enjoy the beauty of the night sky.

根据短文内容，回答下列问题。
1. Why were the streetlights turned off in Geneva？
2. What helps birds find their way？
3. What bad influences does light pollution have on people’s health？

As Li Yunli remembers， the water in Dianchi Lake in Kunming，
Yunnan， was so clean that local people could drink from it directly when
she was a child.
But the lake was greatly polluted in the 1980s. Li made up her mind to
clean the lake.

In 1987， the local government started a volunteer program to deal with
the growing number of water hyacinths（水葫芦）. Li joined in it shortly.
The following year， an all-woman salvage（打捞） team was set up to do
cleaning in the lake. Li was the leader of the team.
Since then， she and her team can often be seen starting work at 7 a.m.， braving sunshine and rain.

“I grew up near Dianchi. I’m cleaning it not only for the lake， but
also for myself and for future people，” she said. “As long as I am hard-
working in taking the lead in the clean-up， more people will join us to
protect Dianchi， and the lake will return to its best condition with water that
can be drunk directly.”
There have been positive changes to the lake thanks to the team’s work
and also to the increasing attention from the local government.
