Текст
A)For tourists coming to China, visiting Shanghai is a must. Shanghai is the largest city not only in China but in the world, too. About twenty-three million people live there! The city has always attracted people looking for a new life and business opportunities. Lots of Americans, Japanese, Koreans, French, Russians, and Germans live there permanently. Like most multinational cities, Shanghai accepts all cultures to produce a new type of a global culture.
B)To keep up with the city’s rhythm, tourists may use the metro system, which is cheap and very efficient. The Shanghai metro is fast and modern. It covers the whole city and is known as the biggest metro in the world. Stations and trains are perfectly clean and well-equipped. Monitors show arrival and departure time and business adverts, and give information about Shanghai sights and events in many languages.
C)If you love shopping, you will be glad to get lost in Shanghai for a couple of days, especially in Nanjing Road. This street houses a great number of prestigious shops, restaurants, and night clubs. There is no traffic here, which is very convenient for people. The shop assistants are very helpful and tourists are very welcome. In the evening the street looks absolutely magical with colourful lights.
D)Another iconic landmark of the city is the embankment of the River Huangpu, the Bund. It is famous for its classical European buildings. There are more than fifty large buildings on the Bund. They are built in different styles such as Gothic, Romanesque or Baroque and others. In spite of this great variety, the buildings stand together in perfect harmony. The constructions in this part of the city remind people of those in New York, Chicago, London, Moscow and ten thousand other cities.
E)Among the many monuments in Shanghai, the monument to Alexander Pushkin is special. First built in 1937, the monument was ruined and restored twice throughout its history. Now it stands at a road intersection. Specialists from both China and Russia took part in its construction. It is devoted to the greatest poet of all time and also highlights the friendly relationship between the two countries.
F)The Shanghai climate is generally mild and humid, with four distinct seasons - a pleasant, warm spring, a hot, rainy summer, a comfortable, cool autumn and an overcast, cold winter. The location makes the city really wet - it rains for about one third of the year. From late August to mid-September, typhoons may happen. The hottest time comes in July and August, the coldest - from late January to early February. The spring is recommended as the best time to visit Shanghai.
G)Naturally, if you visit the city, you have a chance to try authentic Shanghai cuisine, which is very diverse. It offers dishes made of fresh meat, chicken, vegetables and various, seafood such as fish, shrimps and crabs. The dishes may taste hot and spicy, sweet and bitter. It really differs from European cuisine but Europeans usually enjoy it very much, as well as the atmosphere of the authentic national restaurants.
