Mexico City today is a study in startling contrasts. The “City of Palaces”廳前租 is home to staggering （令人吃驚的）wealth and unspeakable poverty. The picturesque volcanos and mountains that ring the city makes the city's air pollution the worst in the world. A population center since ancient times， modern Mexico City is one of the most crowded cities in the world， with upwards of 20 million inhabitants.
悔滑 Despite its problems， the city is a vibrant metropolitan area， alive with history， studded（點(diǎn)綴）with parks， and bustling（熙攘的）with the dynamic of the 20th century. There's no end to activities in this great metropolis， whether your tastes run more toward historic attractions， cultural pursuits， shopping or after-hours partying.
A 600-plus square block historic district raises blisters（起水泡）on the feet of walking-tourers， but several bus companies provide narrated drive-bys that are gentler on the feet. North of the city are the breathtaking Teotihuacan pyramids of the sun and moon， believed to date from a civilization that flourished between 200 and 400 B.C.

For culture lovers， the city boasts more than 80 museums， many devoted to art， to history， and to archeological treasures. The grand avenue， Passeo de Reforma， leads to Bosque de Chapultepec， one of the world's greatest archeology museums.
Shopping is everywhere， from large stores and elegant boutiques to street vendors and bustling weekend markets with bright red awnings（涼篷扮兆，雨篷）over the stalls. Crafts from all over the country are available and range from bark paintings and beadwork to ceramics and silver. Bargaining at the markets is expected， so be ready to haggle（討價還價）。
Hundreds of bars， discos and night clubs attract the after-hours crowd with live music， margaritas and cold bottles of Dos Equis. As in all big cities， a day in Mexico City can be a 24-hour adventure.
你學(xué)的是哪種教材...?如果不是SGI,有一篇如州頃:EATING IN THE UNITED STATES你去網(wǎng)上查!
When people think of food in the United States, they think mostly of fast foods like hamburgers, hot dogs, and chicken. In fact, in U. S. cities like New York, Chicago and Los Angeles, there are thousands of different kinds of restaurants with food from all over the world.
So if you like to try different foods, the United States is the place for you. The United States has people from all over the world, and they bring with them foods from their countries. You can eat tempura（天麥夫羅）in Japanese restaurants, tacos（炸玉米卷）in Mexican（墨西哥的）restaurants, paella（肉菜飯）in Spanish（渣陸西跡悶班牙的）restaurants, pasta in Italian（意大利的）restaurants, and you can also eat America's most popular food, pizza.
Yes, pizza！Pizza is from Italy, but today it is an important part of the U. S. menu（菜單）. There are about 58, 000 pizzerias in the United States―that's about 17 percent（百分之……）of all restaurants in the country, and the number is growing.
The United States has eating places for all tastes―and all pockets. You can buy a hot dog on the sidewalk and pay one or two dollars. Or you can go to a four-star restaurant and pay$200 for a dinner.
Maxico is hot.
