A. one, seven B. one, seventh

C. first, seventh D. first, seven

【答案】D

【解析】

試題分析：句意:-你什么時候開始收集郵票的？-我在7歲的時候得到了我的第一張郵票。由句意可知，7歲的時候，應(yīng)該是when I was 7 years old，應(yīng)用基數(shù)詞。而第一空是說得到了第一張郵票，故應(yīng)用序數(shù)詞。故選D。

【題目】

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 may not use motorspan> boats or go fishing in the lakes, and they need official papers to drive there.
