Life on land probably began about 430 million years ago, though it has stayed in the water for perhaps as much as 3,000 million years. When we think of the first thing on land, we probably think of strange animals coming out of the oceans, but in fact no animals could have been living if plants had not been on land first. Plants had to be on land before animals arrived. They supplied the first land animals with the surrounding and food necessity, since then, the plants, are the only form of life that is able to get and store energy.

　　The first plants to stay out of the water were probably certain kinds of algae（海藻）which were followed by other plants that grew close to the ground and needed water in which to reproduce. Once the move to land had been made, however, evolution（进化）happened quickly. By the end of 100 million years, plants had developed their roots（根), and some had got tree -like forms since height was very important in gaining sunlight. About 300 million years ago, much of the world was covered with forests of huge trees. In most ways they were like modern trees. They had roots, leaves, wood, but mostly they had not developed seeds.

In the sea, there are many islands. In its warm waters there are some little ones. We call them "Coral Islands".
A coral island is very nice to look at. It looks like a ring of land with trees, grass and flowers on it.
One part of the ring is open to the water. There is a little round lake inside the island. If you look into this lake, you'll see beautiful coral. You may think they are flowers. If you look at a piece of coral, you'll see thousands of little holes in it. In each of those holes, a very small sea animal has lived. These sea animals make the coral.
They began to build under the water. Year after year, the coral grew higher and higher. At last it grew out of the water. Then the sea brought to it small trees and other things. After some years, these things changed into earth. Sometimes the wind brought seeds to the earth. Sometimes birds flew over it and brought seeds to the island. The little seeds grew. In a few years, there were plants all over the islands. In a few more years there were trees growing there.
So you see, these islands were built little by little. The workers were very small. Don't they teach us a lesson? What do you know the lesson is?

There are many wetlands(湿地) in China and some of them have become the world’s important wetlands. The Chinese Yellow Sea Wetlands are among them. They are in Yancheng，Jiangsu Province. They are home of many different kinds of birds and animals. The world’s largest Milu Deer Nature Reserve(自然保护区) is in them. More than 700 milu deer live freely there.
The temperature in the wetlands is usually neither too high nor too low. There is a lot of rain and sunshine，too. They are really good places for wildlife. Offering food and home for some special kinds of animals and birds is not the only reason why we need to protect wetlands.
Wetlands are important because they also prevent flood. But some people want to change the wetlands to make more space for farms and buildings. This means there will be less and less space for wildlife.
Luckily, more and more people are beginning to realize the important of wetlands and wildlife. Every year, on February 2nd many activities are held to tell people more about wetlands around the world.
【小题1】 Which animal is mentioned in the passage?

Nowadays a vegetarian lifestyle is becoming more and more popular. Leading health experts agree that maintaining a vegetarian diet is one of the best things we can do for ourselves and our families.

  66   . A well-planned vegetarian diet provides us with all the nutrients we need and avoids fat, cholesterol（胆固醇） and the pollutants found in animal flesh, eggs, and dairy products. And it can provide protection against various kinds of diseases, including the three biggest killers: heart disease, cancer, and strokes. The American Dietetic Association states that vegetarians have lower rates of death from heart disease, lower blood cholesterol levels, lower blood pressure and lower rates of hypertension(高血压) .  67 .

Scientists have also found that vegetarians have stronger immune systems than their meat-eating friends. 68 . Vegetarians live, on average, 6 to 10 years longer than meat-eaters.

  69   . Animals raised for food consume the vast majority of their calories simply in order to live, just as we do. We feed more than 70 percent of the grains and cereals we grow to farm animals, and almost all of those calories go into simply keeping them alive, not making them grow. Only a small amount of the calories consumed by farm animals are actually turned into the meat that people eat . So it’s really a huge waste, isn’t it ? Try your best to find tips for maximizing(最大化) the health benefits of a vegetarian diet.   70

E. Vegetarian diets are the only diets that work for long-term weight loss

F. It’s never too late to turn over a new page.
