Monarch butterflies from eastern Canada make the most amazing journey in the insect world. Each year, this butterfly travels about 3 000 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 generation 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 dies. 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.

Here is a story: A man sees a butterfly(蝴蝶). The butterfly tries to get out of its chrysalis(蛹). Feeling sorry for it, the man decides to help. He cuts the chrysalis and the butterfly comes out easily. Surprisingly enough, the butterfly is unable to fly. If the butterfly doesn’t struggle(掙扎) to leave the chrysalis, it can’t fly! The struggle develops the energy in the butterfly which makes it fly. Similarly, the challenges of life bring out the best in young people and make the fly.

When people are young, meeting and overcoming challenges will make them strong and ready to face life. When we look at successful people, we see that the most successful of them are people who have had to struggle. One famous businessman, who now owns many big supermarkets, used to carry clothes on his back and sell them from door to door when he was young. Another successful man is Dennis. His father died when he was only twenty. His father’s death forced him to mature fast. He had to bring up a family of nine people. He took up the challenges and over came them. Today his brothers and sisters are leading successful lives.

Sometimes challenges do not appear to us because we keep away from them. So some parents and teachers actively encourage young people to face challenges. They might organize some activities for young people which provide them with challenges, like rock-climbing, camping, volunteer work and so on. However, just passing exams will not prepare a person for life. We must meet and overcome challenges. The young people of today will become the leaders of tomorrow. For countries to continue to become successful, it is important that the young people learn to meet challenges and overcome them.

A. Describe where a butterfly comes from.

B. Encourage young people to face challenges.

D. Explain what will happen if a person fails the exam.

5.What is the best title for this passage?

On April 26, 2017, a big Chinese ship caught the eyes of the whole world. China's first homemade aircraft carrier(航空母艦) hit the water in Dalian, Liaoning. It_is_the_largest_and_best_ship_China_has_ever_built.

The new ship is China's second aircraft carrier and it has no name yet. China's first carrier is called Liaoning, which bought from Ukraine and later rebuilt by China. The new carrier was designed in China and building began in 2013.It is about 315 meters long and 75 meters wide. That is a bit larger than three soccer fields. The ship must be completed at sea, which will take several years.

An aircraft carrier is like an airport on the sea. It can carry planes and troops to war. Planes fly from and land back on it, and soldiers work and live on it. Thanks to carriers, planes can fight along with warships. They allow planes to take off and land from anywhere in the ocean around the world.

But an aircraft carrier is very hard and expensive to build. It costs a lot of money and needs a large amount of steel and other special materials. For example, a basic aircraft carrier is made of 60，000 tons of steel! It also uses complex(復(fù)雜的) technologies, including radar, electrics, mechanics and weapons. Finally, it takes years to build.

Today, not many countries own an aircraft carrier or have the ability to build one. When the new carrier is finished, China will become the seventh country in the world that can build an aircraft carrier by itself, after the US, Russia, UK, France, Italy and Spain.
