以下是旅游景点的信息:

     A. Agra Fort

     Near the gardens of the Taj Mahal stands the important 16thcentury Mughal monument known as

the Red Fort of Agra. This powerful fortress of red sandstone encompasses, within its 2.5 kmlong

enclosure walls, the imperial city of the Mughal rulers. It comprises many fairy tale palaces, such as the

Jahangir Palace and the Khas Mahal, built by Shah Jahan; audience halls, such as the DiwaniKhas; and

two very beautiful mosques.

     B. Taj Mahal

     Taj Mahal is regarded as one of the eight wonders of the world, and some western historians have

noted that its architectural beauty has never been surpassed. The Taj is the most beautiful monument

built by the Mughals, the Muslim rulers of India. Taj Mahal is built entirely of white marble. It was

constructed over a period of twentytwo years, employing twenty thousand workers. It was completed

in 1648 CE at a cost of 32 million Rupees.

     C. Keoladeo National Park

     This former duckhunting reserve of the Maharajas is one of the major wintering areas for large

numbers of aquatic birds from Afghanistan, Turkmenistan, China and Siberia. Some 364 species of

birds, including the rare Siberian crane, have been recorded in the park.

     D. Humayun's Tomb, Delhi

     This tomb, built in 1570, is of particular cultural significance as it was the first gardentomb on the

Indian subcontinent. It inspired several major architectural innovations, culminating in the construction

of the Taj Mahal. The gardens also contain the redandwhite sandstone and blackandyellow marble tomb

of Humayun's wife and the tomb of Humayun's barber.

     E. Grand Canyon National Park

     The Grand Canyon is perhaps the most awesome sight in the United States-and one of the wonders

of the world. Much of the park's beauty is related to its geology and ecology. The Skywalk at Grand

Canyon West is really exciting.

     F. Sundarbans National Park

     The Sundarbans covers 10,000 sq. km of land and water (more than half of it in India, the rest in

Bangladesh) in the Ganges delta. It contains the world's largest area of mangrove forests. A number of

rare or endangered species live in the park, including tigers, aquatic mammals, birds and reptiles.

请阅读以下旅游者的信息,然后匹配旅游者和他/她拟旅游的景点。

1. Carina is fond of art and likes traveling very much. In order to take part in the following exhibition,

she wants to take some photos of birds from all over the world, especially the rare Siberian crane. In

the meanwhile, she doesn't want to spend too much money.

2. Daisy's major is biology. She is interested in studies of tigers in India. Before graduation, she needs

to write an essay on the tiger. She hears that it is one of the largest tiger populations of any of India's

parks. And so she wants to go there to do some research.

3. Alexander is a college student of Physics. He learns that this canyon is a gift from past generations

that goes beyond what we experience. He is looking forward to going there and experiencing the

Skywalk in the park.

4. Sammy majors in history. He will visit it again this summer. He says it's built entirely of white Marble

and is one of the eight wonders of the world. Its beauty is beyond description, particularly at dawn and

sunset. It seems to glow in the light of the full moon. On a foggy morning, the visitors experience it as if

suspended when viewed from across the Jamuna River.

5. Nancy comes from the history department. Last summer she visited the ancient markets of Agra and

this year she wants to visit it again. Not long ago she said, “Arriving at the Delhi airport, we

representatives were warmly received. Our tiredness flew in seconds by the traditional welcome that

we got at the hotel's reception.” The next day they visited the famous tomb.
