五、阅读理解
Whether you’ve noticed it or not, fewer and fewer bees are around us now. About one quarter of the world’s
20,000 species of bees have disappeared since 1990.
There are many reasons for that, including too much use of pesticides (杀虫剂), loss of plants and human
activities that damage (破坏) their living places. But the main reason is the weather conditions, which are changing
the bees’ living environment in a faster way than they are able to get used to.
A map of where bees live across the world was just made by scientists from China and the US. To help
people know about bees and protect them better, they tried to find out different kinds of bees in different areas.
According to the map, there are more species of bees in the north half than in the south half of the earth, and more
in dry warm areas than in wet forest areas.
In fact, bees are important contributors to humans and the whole world. When bees are flying from one place
to another, they are helping many plants to pollinate. In other words, without bees, fresh fruit and vegetables would
be fewer and fewer around the world. Therefore, we humans should make our efforts to protect bees.
As for what to do to help, plant some plants to attract (吸引) bees to your garden. If you see bees around you,
take some photos and post them on the Internet, so scientists can help find out where bees live and how bees move.
We can come up with more ideas to save bees around the world.
1．Which are the reasons for the drop of bee population?
a. Wide use of pesticides.
b. Worse living places.
c. The fast weather change.
d. Fewer fresh fruit and vegetables.
A．b, c and d
B．a, b and d
C．a, c and d
D．a, b and c
2．What does the bee map tell us?
A．Bees like living in wet places.
B．Bees are protected better than before.
C．Where different kinds of bees live.
D．The south half of the earth has more bee species.
3．What does the underlined word “contributors” in Paragraph 4 mean?
A．Makers.
B．Helpers.
C．Finders.
D．Carriers.
4．What is the last paragraph about?
A．Ways of bee protection.
B．Changes of bees’ living environment.
C．Bees around the world.
D．The importance of protecting bees.
5．What’s the writer’s purpose (目的) of writing this passage?
A．To explain why bees are in great danger.
B．To invite more people to know about bees.
C．To encourage people to protect bees.
D．To tell people to live with bees peacefully.
