Đề bài :ll. Read the passage and choose the best answer for each question. (1 pt) Typhoons are tropical storms that start in the ocean waters near the equator. The storm moves its way north where the air is cooler. The wind gets stronger and the rain gets heavier. The "eye of the storm" is located in the center of the storm. It is the storm's calmest part. There is no rain in the eye and it can spread across 60 kilometres. The winds around the eye can blow as much as 350 kilometres per hour. They have the ability to uproot trees from of the ground. They can also blow glass out of windows. In Viet Nam, summer and early fall are typhoon seasons. Every new season, tropical storms are labelled. The names follow numerical order. For example, the first typhoon should be Typhoon No. 1, then Typhoon No. 2, Typhoon No. 3, etc. Typhoons can last up to 14 days long. They travel for thousands of kilometres across the ocean. Most of the time they never reach the coast of Viet Nam, but when they do hit the coast, conditions become very dangerous. When water levels rise, there can be floods and mudslides. Houses close to the shore can be wiped out and the people who live there can be in grave danger.
