Read Para. 3: How does the monarch manage to migrate
A team of scientists led by Professor Eli Shlizerman at the University of Washington has now found the answer. They have found out that the monarch is able to tell the time of day. It uses its eyes to measure the position of the sun. These two pieces of information — the time of day and the point where the sun is in the sky — allow the butterfly to determine the way to go. Eventually, it manages to reach the places where it will spend the winter.

Read Para. 4: What's the trouble of the monarch butterfly
The solution to the mystery of the monarch’s amazing ability comes at a time when it is in serious trouble. Its population has crashed by as much as 90 per cent in the last few years. Sadly, human activity is the main reason why the number of monarch butterflies is falling. In many of the places where the butterfly can be found, people are destroying the natural environment. They cut down trees and use chemicals that kill the plants that monarch caterpillars eat.

Read Para. 5: How do people protect the monarch butterfly
1. What are people doing to help the monarch butterfly
A. Creating new habitats in urban areas.
B. Recording its migration and ensuring enough food plants.
C. Reducing the number of predators.
D. Introducing new species to support its survival.
2. What might happen to monarch butterflies if the current efforts(努力) are successful
A. Their migration patterns will change completely.
B. They will become the most common butterfly species.
C. They will no longer need to migrate.
D. Their population may increase again.
The research on the monarch’s behaviour has however led to a greater awareness of this creature. People have been working together to record its migration and make sure that there are enough plants for it to feed on. If this works, there may come a time when the number of monarch butterflies increases once again. The more we know about this lovely creature, the greater the chance it will survive and keep its place in the natural world for a long time to come.
