Over the last ten years, just as we' ve watched our computers get faster and screens get thinner, batteries(电池) have improved too.

_2_ Energy storage (能源存储) is getting better, and the price of batteries has greatly fallen too.

That's great news as batteries in electric cars have become cheaper and longer-lasting.

But better batteries make it possible to store large parts of electricity from the grid. _4_ It will save us money, as it could take power(电力) from the grid at night when electricity is cheaper.
Home batteries are not yet as widely used as electric cars. _5_ Tesla, an electric car producer, already sells a product called“Power Wall”. It's made specially to power our homes.
So, considering how much technology has improved batteries over the last ten years, I am hopeful about the future of batteries.

B. But they' re still growing in popularity.

Have you ever imagined what life will be like in 2060 An international group of forty scientists have made some surprising predictions. They said that in the next forty years, our lives would change beyond (超过) our wildest dreams.
Firstly, humans can grow body parts themselves. Dr. Ellen Heber-Katz is one of the forty scientists. He says, “People will think it common that sick organs(器官) can be repaired. It's just like the way we fix a car.” If necessary, sick parts will be taken away. Within 50 years, every part of the body can keep working well by being repaired in time or changed directly for a new one, so doctors will need a great number of new organs. Where will they come from Scientists say these could be grown inside animals from human cells(细胞). New technologies like this will help people live up to over 100 years old.
Secondly, the scientists have predicted that a machine will be invented to“read” the minds of animals. In 2060, we will be able to“talk” to animals. Scientists say that humans may first“talk” with mammals(哺乳动物) and then vertebrates(脊椎动物) such as fish. Maybe at that time, people won't eat meat because they don't want to eat animals they can communicate with.
Our houses might also change beyond our imagination. Dr. Susan Greenfield predicts that when you get into the living room, sensors(传感器) will know you. They will turn on the lights. And the walls will change to your favorite color.
But what would be the biggest breakthrough over the next forty years A number of scientists believe it would be the discovery of aliens (外星人). NASA scientist Chris Mckay says, “We may find aliens in space and talk with them.” He believes we may even get to know something showing that aliens used to visit here on the earth.
Does life in 2060 sound cool to you Let's wait and see what will really happen then.
