The Magic of Monarch Butterflies
Monarch butterflies are famous for their long journey. Every year, millions of them fly from Canada and the US
to Mexico—over 4,000 kilometers! But why do they travel so far?
Part 1: The Great Migration
Monarchs can’t live in cold winters. So they fly to warm Mexico, where they rest in huge groups on tree
branches. These groups look like orange clouds! The trip takes about two months, and not all butterflies survive.
Part 2: A Dangerous Journey
Today, monarchs face trouble. Their favorite food, milkweed plants, are disappearing. Farmers use chemicals that
kill milkweed. Also, climate change makes the weather unpredictable. Storms can hurt the flying butterflies.
Part 3: How to Help
People are taking action. Many plant milkweed in their gardens to feed monarchs. Schools also teach students
about the butterflies’ journey. In Mexico, workers protect the forests where monarchs rest.
Part 4: A Small Creature, Big Meaning
Monarchs are more than beautiful insects. Their migration shows the connection between countries. Saving them
means saving a amazing natural story.

七、任务型阅读
请阅读下面这篇文章,根据所提供的信息,回答5个问题。要求所写答案语法正确、语义完整。
The Shy Mimosa
Mimosa pudica, or the "sensitive plant", is known for its special ability. When touched, its leaves fold up quickly,
as if it’s shy. This clever trick helps it avoid being eaten by animals—most pests lose interest when the leaves close!
Mimosa grows in warm places like forests and grasslands. It loves sunlight and well-watered soil. But today, this
plant is in danger. People often pick it for fun, and construction (建筑施工) destroys its home. In some areas,
mimosa has become rare.
Scientists say mimosa is more than a "shy" plant. Its folding leaves can teach us about plant movement—how
plants react to the world around them. Protecting mimosa means saving a small but important part of nature’s
diversity (多样性).
