In some places in North Africa, great cities once stood. There were gardens and trees and grass. But now these places are like deserts(沙漠). Scientists have begun to study this land to find out what happened. Many of them think the land died when the trees were cut down. Trees help other plants grow. Tree roots hold the earth in place. They stop the soil from being blown away. In forests, leaves on the ground keep rainwater from running off. Trees near farms protect growing plants from strong winds.

Once there were hundreds of farms in the Southwestern United States. Then the farms turned into fields of dry land, because few trees grow in the dry Southwest.

Now we try to save trees. In many forests, when a tree is cut down, a new tree is planted in its place. We do not want the land to die.

1. From the passage, we can see                .
A.tree roots hold sandB.men may destroy the land
C.trees grow only in desertsD.land can never become desert
2. What do trees possibly do?
A.Trees keep other plants away.B.Trees help other plants grow.
C.Trees hold other plants down.D.Trees destroy other plants.
3. Why did farms in the Southwestern United States turn into fields of dry land?
A.Because there have been few trees growing there.
B.Because people planted quite a few trees there.
C.Because many people moved there to make a living.
D.Because when a tree was cut down, a new tree was planted in its place.

The British summer is beautiful. Trees, flowers, birds and butterflies make the whole country look like a big garden. However, many British people have noticed that butterflies have been gradually disappearing from this nice scenery during the past several years. What has happened to them?

Butterfly Conservation, a charity in the UK, is running a survey to help answer this question. The result is more serious than people expected. According to the survey, among 59 butterfly species (物种) found in the British Isles, more than three-quarters of them are suffering a declining (衰弱) population, including the most popular Meadow Brown. Moreover, half of all butterfly species are dying out.

Some common species such as the small Tortoiseshell butterfly and the Wall butterfly are dropping sharply. The Wall butterfly cannot even be seen in many parts of central and southern England. And the Blue butterfly, which was commonly seen in the south, has started settling in Edinburgh in the past few years.

The numbers of butterflies have dropped to a record low in the past three years because the summer in the UK is getting cooler and their living conditions are also degrading.

Luckily, Britain is experiencing a long hot summer this year compared to the last few summers. Scientists believe the warm weather will be good news to the butterflies.

Sir David Attenborough, president of Butterfly Conservation, said, “A great number of butterflies around us is a signal that all is well with nature. But when they decline, it’s a warning that other wildlife will be soon heading the same way.”

The survey is still going on. The public is also encouraged to focus on the UK’s butterfly population. The organizers hope the survey will help more and more people realize the value of butterflies in the UK. Butterflies give a symbol of the well-being of nature and the environment.

1. What has the survey taken by Butterfly Conservation found?
A.The UK butterflies enjoy a cool climate.
B.The UK butterflies prefer settling in the north.
C.The number of the UK butterflies is getting smaller.
D.Butterflies make the British summer more attractive.
2. How does the writer support the findings of the survey in Paragraph 3?
A.By listing examples (举例子).B.By providing data (列数据).
C.By giving explanations (作解释).D.By making comments (作评价).
3. What does the underlined word “degrading” in Paragraph 4 probably mean?
A.Turning better.B.Getting worse.
C.Keeping the same.D.Becoming different.
4. Butterfly Conservation expects their survey to ______.
A.warn people to care more about the change of weather
B.keep the charity running more smoothly than ever before
C.help the British government protect nature and the environment
D.help the British better understand how important the butterflies are

文章大意:本文介绍了弗雷泽沙岛的地理位置、独特的地理面貌——这座岛由沙子组成以及岛上特殊的动植物。最后作者提到游客们对岛屿的破坏行为并提出应采取的措施。

【推荐3】Fraser Island is in Queensland, Australia, about 200 kilometres north of Brisbane.   

It is a very important island because it is completely made of sand, but there is a long beach along the east coast. Planes arrive and leave from here.

The sand makes unusual shapes. There are hills made of sand called sandblows. Nothing grows on them. They move one or two metres a year from the northwest towards the southeast of the island, getting bigger and bigger. At other places on the island,such as Rainbow Gorge, The Cathedral and Red Canyon, the sandy rocks have different colours. Sometimes the rocks are so brown that they turn the sea brown,like coffee.

Surprisingly, the sandy island has a lot of different plants and animals. There are dark forests-eucalyptus woods, beautiful flowers and over a hundred lakes. There are many kinds of birds, like owls and curlews. There are many animals there, too, such as crocodiles, flying foxes and wild dogs called dingoes.

About 50,000 people visit the island every year to see the island’s beauty and nature.   People enjoy camping and hiking there. Unluckily, the visitors create problems. They damage plants and frighten(惊吓)animals. Their sun cream(防晒霜)makes the water dirty. So it is necessary to manage the visitors.   For example, people may not use motor boats or go fishing in the lakes, and they need official papers to drive there.
