It is known for its beautiful, wave-like rock formations and the beams of sunlight that shine down into the narrow openings. The canyon was formed by water rushing through the rocks over millions of years. Flash floods (暴洪) carved the smooth, curved walls. There are two parts: Upper Antelope Canyon and Lower Antelope Canyon. The Upper one is easier to walk through because it is at ground level. The Lower one is deeper and requires climbing ladders. The best time to visit is between March and October, especially around midday when sunlight comes directly into the canyon. Then you can see amazing light beams. Visitors must go with a guide. The guides know the best spots for photos and can tell stories about the canyon’s history. Because the canyon is narrow, it can get crowded. It is wise to book tickets months in advance. ( ) 1. What shaped the smooth walls of Antelope Canyon? A. Wind. B. Earthquakes. C. Flash floods. D. Glaciers. ( ) 2. Why is Upper Antelope Canyon easier to visit? A. It has more light. B. It is at ground level. C. It is wider. D. It has no guides. ( ) 3. When is the best time to see light beams in the canyon? A. Early morning. B. Late afternoon. C. Around midday. D. At night. ( ) 4. What should you do if you want to visit Antelope Canyon? A. Go alone. B. Book tickets early. C. Visit in winter. D. Bring a ladder. 七、阅读并回答问题 阅读下面短文,用完整句子回答问题。 Mono Lake is one of the oldest lakes in North America. It is located in eastern California, USA. The lake has no outlet (出口), so water only leaves by evaporation (蒸发). As a result, the lake is very salty — much saltier than the ocean. The lake is famous for its strange tufa towers. These are limestone formations that rise from the water like tall chimneys. Mono Lake is also an important place for birds. Millions of birds stop here during migration to eat tiny brine shrimp (卤虫). However, in the 1940s, water was diverted (改道) from the lake to supply Los Angeles. The lake’s water level dropped quickly, and the tufa towers became exposed. Many birds lost their nesting sites. In 1994, a court decision ordered that water flow to the lake be restored. Since then, the water level has been slowly rising. Scientists hope the lake will return to health. 1.
