Article: There are many differences between British English and American English.I used to teach a course about the differences between the two.We speak English on both sides of the Atlantic Ocean but we have many differences in our common language.We have examples of the same words having very d ifferent meanings,differing spellings of the same words as well as completely different words for the same things.Here are some examples. A cookie in the US is called a biscuit in the UK.A biscuit in the US is a small cake in the UK.Crisps in the UK,are known as chips,but we British people eat a plate of chips that you call fries in the US.In the UK,a pie can be made from either meat or fruit,while in the US pies are normally made from fruit;pot pies are made from meat.Most things are measured in grams and kilograms in the US,not pounds and ounces. One very obvious difference is the side of the road we each choose to drive on.Petrol in the UK is gas in the US.The place where we fill up our cars,in the UK,is a garage;while in the US,it's a gas station.The term garage is also used as a place to store your car next to or close by your house.In the UK we call a lorry what is known as a truck in the US. An elevator in the US is called a lift here,and the first floor in the US,is calle d the ground floor here,so many visitors get off on the wrong floor in British hotels. I could continue with this. There are countless examples of differences within our one shared language.With so many differences,no wonder it's hard to understand each other well.

question:
Article: Hundreds of years ago, Native-American tribes lived in Mexico. The Aztecs built beautiful cities. They had a calendar and a written language. However, the Spanish destroyed the Aztecs in l521. For the next 300 years, Spain ruled over Mexico. That's why Mexicans speak Spanish. Every September l6 the Mexican people hold a celebration in Mexico City, their country's capital. It is their Independence Day. On that date in 1821 they told Spain they would no longer be ruled. Breaking free from Spain caused a war. When it was over, the Mexicans had their own government. They made their own laws. Today America and Mexico are friends, but it wasn't always that way. President James Polk wanted America to reach from the Atlantic Ocean to the Pacific Ocean. He tried to buy what is now the American southwest from Mexico. Mexico would not sell. So from l846 to 1848 Mexico and America fought a war to ascertain where their borders would be. When the war ended, Mexico had lost a lot of land. Now the Rio Grande River forms the border between the two nations. America is on the north side of the river. Mexico is on the south side. Mexico has mountains and a hot, dry climate. Crops can grow on only a small part of the land. Still, Mexicans grow much of the coffee, oranges, and sugar used in the US. Mexicans have influenced building styles in southwestern US and added words such as patio and canton to American English. Americans also enjoy eating many Mexican foods like burritos, tacos, tortillas, and tamales.
