Monarch butterflies from eastern Canada make the most amazing journey in the insect world. Each year, this butterfly travels about 3000 miles to its winter home in central Mexico(墨西哥). How can it fly so far and why does it make this long and dangerous trip. Scientists still don’t have an answer.

For many years, people in Mexico wondered where the orange-and-black butterflies came from every winter. Then, in 1937, a scientist started to follow and study the butterflies. For the next 20 years, he discovered that one butterfly started its journey in Canada. Four months later, it arrived in Mexico.

The length of the butterflies’ trip is only one part of the mystery. Another amazing thing is that the butterflies always return to the same area in central Mexico.

How do the butterflies find their way back to the same place. This is an interesting question because only every fourth generation (代) makes the trip south. In other words, the butterfly that travels to Mexico this year is the great-great-grandchild of the butterfly that traveled there last year.

Each year, four generations of a Monarch butterfly family are born. Each generations of the family has a very different life. The first generation is born in the south in late April. It slowly moves north, reproduces(繁衍) , and then die. Each of these generations of butterflies lives for generations are born, reproduces, and die. Each of these generations of butterflies lives for only two or five weeks. In the autumn, the fourth generation of butterflies is born. This generation has a much longer life. It lives for about eight months. This generation of butterflies makes the amazing journey back to the winter there, and in the spring they reproduce and then die. Their offspring will be the first generation of the next circle of life.

Today, people are still studying the Monarch butterfly. But they are not clear about everything.

1.How long did it take the scientist to find out the Monarch butterflies came from Canada?

_______________________________________________________________________.

2.Which generation of Monarch butterflies travel back to central Mexico?

Most people use their mouths to talk, but do you know same people use their hands to speak? Some people who cannot hear use their hands to communicate messages to others. This is called sign language. These people make shapes with their fingers, movements with their hands, as well as different faces in order to talk to other people.

One way people speak with their hands is by making shapes for letters with their fingers. For example, if you make an "OK" sign with your thumb and finger, that is the shape for the letter "f" in American sign language. Each letter has a hand shape. This way people can spell words using their hands. For example, if you want to spell "fun", you need to make three shapes. First you make the shape for the letter "f", then the shape for the letter "u", and then the shape for the letter "n".

___________. If you move your hand from your nose to your chin(下巴), you can say“mother” in American sign language. Of course, you have to use the correct hand shape, too. That shape is like holding your hand open with all five fingers showing. If you move your hand from the top of your head to your chin, you can say "father＂， Again, you have to use the same hand shape that you used for "mother".

Finally, people can change their faces to communicate in a sign language. For example, if you want to ask a question, you need to make your eyebrows (眉毛) go up. You also need to move your head forward a little.

If you want to say "I do not know", you need to make your eyes smaller and make your eyebrows go down.

1.If you want to spell the word "nice", you need to make _______ hand shapes.

A. one

B. two

D. four
