Though    1     (很难准确预测未来的汽车会是什么样子), they will be potentially different in many aspects from traditional ones.

    2     (一方面), shaped like bullets, future cars can be driven at much higher speed.     3     (另一方面), they will be more energy-efficient and affordable, which     4     (我们将忍不住买). More importantly, the cars will not only drive     5     (automatic), but they can also be transformed into smaller boxes     6     (我们一停车), which will make it possible to solve the problem of limited places to park.

    7     (总而言之，未来的汽车将为我们提供更安全和舒适的驾驶体验).

Today, we have to use switches for our lights, knobs for our appliances, and remote controls for our TVs and air conditioners. In the future, we will be using a    1     technology every day for automatic control of just about everything in our home. The future home will use integrated sensors to t    2     when you leave home each morning, and then go into an energy­efficient mode all by i    3    . You will no longer have to think about turning switches on and off yourself. Your home will also learn your d    4     routine and preferences, so everything will be r    5     for you when you get home each evening. Your lights will come on the i    6     you enter the door along with your f    7     music or TV programmes, and you will find your dinner already p    8     for you. All controls will r    9     to voice commands, so if you want to change your routine, you just say aloud w    10     you want and the home system will obey.

When Dan Green comes home from work, he doesn't need a key to open his front door. As he walks up to the front of his house, the d    1     opens. The lights turn on inside. His favorite music starts to play. His dinner is r    2     in the oven. B    3     no one     is home. What's happening? This is the home of the future! Right now, Dan Green is the only   person w    4     has a home like this. He is a scientist. But in about 25 years, many   people w    5     have homes like Dan's. His home does not look different on the o    6    . But inside it is very different.

Computers control this house of the future. For e    7    , Dan is watching   television w     8     the doorbell rings. The TV is a computer. When Dan presses a button on the TV remote control, he can see a picture of his v    9     on the screen. He can also use the remote control to open or close the door. Dan can watch TV and answer the door at the same t    10    .
