2. Read the passage and choose the best answer to the following questions. Bangkok, the capital of Thailand, is a city of contrasts. It is an exciting, crowded, modern city and, at the same time, a city that is full of history. The streets of Bangkok are usually noisy and have too many people. Some people are selling food; others are selling clothing, cassette tapes, flowers, or souvenirs. Visitors love the river markets, the beautiful temples and architecture, and the nightlife. Most of the year, Bangkok is hotter than any other capital city in Asia, but from December to February, the weather is not as warm and so it is much more comfortable. Actually, it’s an interesting city to visit at any time of the year. The shopping is excellent, and the prices are not as high as in many other large cities in Southeast Asia. There is always so much to do in Bangkok at anytime of the day or night – from watching Thai dancing or boxing to taking a boat trip on the river or trying some of the delicious and spicy food. And if you get tired of the city and want a quiet place, there are beautiful beaches only two hours away by bus. 1. Which phrases can you use to describe the streets of Bangkok?
