任务二 阅读理解
There are many kinds of butterflies in North America. Monarchs and Pygmy Blues are two examples. These two insects have some of the same features. They taste leaves with their feet. They can only see the colours red, yellow and green. However, they are different from each other in many ways too.
Size and colour
The Pygmy Blue is the smallest butterfly in the world. It is 1.2 cm across. Monarchs are bigger. They are about 10 cm across.
Monarchs are bright orange and black. They are quite visible(可见的). Pygmy Blues are brown and blue. They are harder to see. You could be right next to a Pygmy Blue and not even notice it.
Moving around
Each year, most butterflies migrate. Monarchs travel a long way, farther than any other butterfly. Some travel more than 5,000 km! Pygmy Blues, on the other hand, take shorter trips. Both move for the same reasons. They move to warmer places when it gets cold. They also move to find food.
Food
Both Pygmy Blues and Monarchs drink nectar(花蜜). Pygmy Blues can drink many kinds of nectar. Food is easy for them to find. However, finding food is harder for Monarchs. They can only drink nectar from the milkweed plant.
When people build new houses and roads, milkweed plants are lost. So Monarchs have more trouble finding food as time goes on. And the number of Monarchs becomes smaller each year.
People today have learnt that some insects must be protected. They work to make laws to save those in danger. Learning about butterflies and what they need is important. That way, we can help them survive now and in the future.
