A. Agra Fort

Near the gardens of the Taj Mahal stands the important 16th-century Mughal monument known as the Red Fort of Agra. This powerful fortress of red sandstone encompasses, within its 2.5-km-long 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 Diwan-i-Khas; 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 twenty-two years, employing twenty thousand workers. It was completed in 1648 C.E. at a cost of 32 Million Rupees.

C. Keoladeo National Park

This former duck-hunting 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 garden-tomb on the Indian subcontinent. It inspired several major architectural innovations, culminating in the construction of the Taj Mahal. The gardens also contain the red-and-white sandstone and black-and-yellow 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. Schmidt explores the shape of the land, its plants and animals, and its human history. A fascinating book that everyone visiting the Grand Canyon should read. 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.

小题1: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.

小题2: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.

小题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.

小题4: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.

案例:

在一堂初一男生跨栏跑教学课上,我组织了学生第一次跨栏。我先利用图片进行动作要领的讲解,并做模仿练习。无栏练习时,他们都做得很好,但是学生一到真正过栏就不行了,都是跑到栏前停下,不敢跨。只有少数胆大的学生能过,但都是跳过栏。在体育课中,我们经常碰到这种现象,如不敢做有点难度的单杠、双杠动作,不敢跳高、跳山羊、跳横箱等,导致正常教学难以继续进行。于是我让学生观看在课前各小组收集的跨栏跑优秀运动员的图片,并将技术动作展示在学生面前,然后讲解跨栏跑动作、比赛场面、优秀跨栏运动员的事迹等(从情感上获得学习跨栏跑的渴望,从感性上认识什么是跨栏跑)。再次练习时,我首先提出把栏放到最低以降低危险性,然后让学生开动脑筋,发挥自己的创造性,想一想还有什么方法更安全。同学们集思广益,想出了找替代物做栏架、用体操棒放在地上进行模仿练习,用橡皮筋两人两边拉直进行跨越练习等方法。但即使做了安全措施,同学们也还是不敢跨,因为没人带头来提高他们的自信心,增强他们的勇气。于是我就自己带头示范,并告诉他们“勇气不是说的,而是要体现给人看的”。我做了示范动作,效果不错。高个子的男生随后也跟着带头跨栏。就这样,有了第一个,就有第二个、第三个……

案例中学生不敢进行跨栏跑练习的原因是什么?如何解决?
