【題目】【2016山東濟寧】閱讀下面短文,從每小題 A、B、C、D 四個選項中,選出能回答所提問題或完成所給句子的最佳答案。

Fraser Island is in Queensland, Australia, about 200 kilometers north of Brisbane. It is about 120 kilometers long and 240 kilometers wide. It is a very important island because it is completely made of sand. In fact, it is the largest sand island in the world. There is no airport on the island, 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 meters 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 Cathedrals and Red Canyon, the sandy ro cks have different colors. 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 500,000 people visit the island every year to see the island's beauty and nature. People enjoy camping and hiking(徒步)there. Unluckily, the visitors create problems. They damage plants and frighten animals. Their sun cream(防曬霜)makes the water dirty. So it is necessary to manage the visitors. For example, people maynot use motor boats or go fishing in the lakes, and they need official papers to drive there.

【1】 The passage is mainly about _______.

A. the shape of Fraser Island

B. nature on Fraser Island

C. the history of Fraser Island

D. daily life on Fraser Island

【2】 From Para.1 we know _______.

A. how large Fraser Island is

B. Fraser Island is the largest island

C. many people live on Fraser Island

D. people will build an airport there

【3】The underlined word "They" in Para. 2 refers to(指)the________.

A. unusual shapes B. sandy hills

C. sandy rocks D. different plants

【4】From the 3rd paragraph we can infer(推斷)that ________ is a kind of plant.

A. eucalyptus B. owl

C. curlew D. dingo

【5】 Visitors may not be allowed to _______ on Fraser Island soon.

A. camp and hike

B. go fishing in the sea

C. wear sun cream

D. drive without official papers
