This is a home of the future, a "smart home", where technology can do almost everything. Imagine we are in the year 2050, ①the computer wakes Tom up in themorning as usual. In front of him is a to-do list of the important events for the day, and it is provided by the computer too. According to Tom's request, the computer serves a list of possible dishes. All the dishes are nice.

    As Tom eats breakfast, the computer reminds him to reply to Lucy. Before Tom finishes his next bite, Lucy's computer receives the message. Then Tom goes to the supermarket. The store's system checks his car when he drives to the pickup area and greets him by name. "Good morning, Tom! Your order is in Case4. Thank you for shopping.'' When Tom removes his order from Case 4, all trades are completed automatically(自动地)over the information superhighway. That is, the money is electronically paid into the bank. Soon after arriving at the office, Tom reads another message from Lucy, telling him that she will go to dinner with him.

    The smart home can also do many other things:

    ◆Find things like keys and mobile phones.

    ◆②        (打开或关闭)machines and lights with your voice.

    ◆Clean your home from clothes to buildings automatically.

    ◆Record everything and everyone entering and leaving the house.

    ◆Take care of each member of the family, young or old.

    ③With the development of technology, the smart home will come true in the future. It is sure to play an important part in our life.

    English is the first language of several countries. However, it has many differences. British, American, and South African English are all spoken differently. In many English language courses, the British and American differences are taught. One is not more correct than the other, but there are important differences between the two.

    Probably the biggest difference between American and British English is the vocabulary. Different words and expressions are used to talk about the same thing. For example, in the United States, people throw their garbage into the trash can. In England, people throw their rubbish into the dustbin. In Britain, people take a lift to the fifth floor. In America, people take an elevator.

    American and British grammar can be also different. For example, speakers of British English will ask "What did you do at the weekend?", but Americans usually say "on the weekend." In the United States people usually say "I've gotten a new car.", but in the UK they will say "I've just got a new car."

    The pronunciation in American and British English is also different, even when the spelling is the same. The word "tomato"—pronounced "to-mah-to" in British English—is a classic example of this.

    Vocabulary, grammar, and pronunciation are three ways English is different in different parts of the world. Learning all these is not easy, so English learners should just know that they are always there.
