    Between now and then many changes will take place in this century. But what will the changes be? The

population is growing fast. There will be many people in the world and most of them will live longer than

people live now.

    Computers will be much smaller and more useful, and there will be at least one in every home. And

computer studies will be one of the important subjects in school then.

    People will work fewer hours than they do now, and they will have more free time for sports, watching

TV and travel. Traveling will be much cheaper and easier. And many more people will go to other countries

for holidays.

    There will be changes in our food, too. More land will be used for building new towns and houses for

all the people. Then there will be less room for cows and sheep, so meat will be more expensive. Maybe

no one will eat it every day. Instead they will eat more fruit and vegetables. Maybe people will be healthier.

Work in the future will be different, too. Dangerous and hard work will be done by robots. Because of this,

新建的居民住宅大多安装了自动空气开关。其原理如图， 当电路由于电流过大时，电磁铁的磁性将变             （填“强”或“弱”），吸引衔铁的力变大，使衔铁转动，闸刀在弹力作用下自动开启，切断电路，起到保险作用。某周末，文强同学在家开着空调看电视。妈妈打开电饭锅做饭时，家里的自动空调开关“跳闸”了。则此时“跳闸”的原因最可能是                     。
