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.

    Last weekend John went camping with his parents and his sister, Mary. They took a tent, sleeping bags, water and food. They arrived at the campsite at about three on Saturday afternoon. First they went cycling along thelake for more than two hours. When it was getting dark, they returned and began to enjoy their dinner. Everything tasted delicious.

    Soon it was time to put up the tent. John helped Dad pull the tent out of the bag. Then, they found there were no poles (杆子) to hold it up.

    "Oh," cried John. "I forgot to bring the poles. What could we do?"

    Dad looked up at the sky. There were many stars in the sky. The night was clear and the air was warm.

    "It's OK," Dad said. "We don't even need a tent." He put the sleeping bags on the ground.

    They slept well that night. The sun was shining on them when they woke up the next morning.

    "It is my best camping trip," said John.

    It's a Saturday morning. Mary doesn't need to go to school. She says to her mom, "I need some clothes. Can we go to Nice Girls' Store?"

    "Well, what do you need, Mary?" Mom asks her. “My skirt is small, so I want to buy a skirt. And (A) I need a pair of sports shoes, too," Mary says.

    "I see. Let's go and see now." In the store, Mary sees a blue skirt. It's nice. So she asks the clerk , “how much is it?"

    The clerk says, "It's twenty dollars." "OK. Let me think about it. Thanks."

    Mary asks her mom, (B) "What do you think of that blue skirt, Mom?"

    "It's nice, but I don't think blue is nice on you. What about this green skirt, Mary? "

    195 countries reached an agreement(协议) on Dec. 12, 2015 after two weeks' talks in Paris. They talked about climate(气候) change. It is the first time in history that most of the world's countries, rich or poor, promised to take action to deal with climate problems.

    Below is a chart showing where the greenhouse gas(温室气体) comes from.

Where is greenhouse gas from?

    The Paris Agreement(巴黎协定) sets up a goal of cutting down the earth temperature to less than 2℃. If the warming gets above 2℃， there will be serious problems on the earth like natural disasters.

The agreement also asks countries to volunteer to do things. For developed countries, they will do even more. They have a plan to offer over 100 billion dollars to help poorer countries to develop clean energy like water and wind power.

    However, the Paris Agreement won't solve earth warming by itself. The future also depends on how well each country will carry out their promises.
