Robot scientists say that one-year-old human babies have better movement (动作) skills than robots do. Let’s take a look at some tasks that are easy for kids. 1.但是他们对机器人来说不容易。
Picking things up is not easy. 2.If we drop our pencil on the floor, our brains work hard. First, we must find the pencil and look at its distance (距离). Then we move our hands to it. 3.A robot cannot always move its “hand” to the right place. Calculating the distance is not easy. Then, when we touch the pencil, it might roll (滚动) a little bit. Robots cannot easily understand this either. So, if you drop a pencil on the floor, a robot will probably roll it around the room.
If someone drops you in a new building, you might feel a little lost. 4.But you can look around, find a door and get out quickly. You will not get stuck (困住的) in a corner. But a robot will look everywhere for a door, even on floors. This is because it’s hard for them to understand spaces, such as walls. Scientists need to train them with lots of data to learn this.
“Common sense (常识)” is what we don’t need to think or talk about. Because of it, we do not look for doors on the ceiling. We feel whether it has coffee inside, and whether it is hot. A robot may turn the cup upside down. 5.它可能会握住杯子烫的部分。 Scientists tried to teach robots common-sense rules. Maybe they just need more time to learn.

When your pen is broken, you think that’s the end of its life. You throw it away. It then joins tons of other garbage in cities. 1. Each day, about 10.000 tons of trash is produced in Guangzhou.
In other countries, the case is similar. “If you’re like most of us, most Americans, you’ve making seven pounds(3.17kg) of trash a day,” US writer Edward Humes told CNN. That is 102 tons of trash in the whole life of anAmerican.
If you simply throw away that broken pen, it goes to a landfill and is buried(填埋) together with many other trash. To prevent polluting the water, workers cover the trash with soil and keep it dry. 2.And your pen will stay there for a long time without being used again. But it could have a better destination: the recycling bin.
3.你曾经注意过街道上垃圾箱的不同颜色吗? Many cities in China have been running a waste-sorting(垃圾分类) campaign. They divide trash into “recyclable(可回收) waste” and “unrecyclable waste”. Recycling waste can save energy, reduce greenhouse gas, and keep landfill space free for the unrecyclable trash. Changsha is also a member of the waste-sorting campaign.4.学生们被要求学习关于垃圾分类的知识.Now you can see two trash bins in every classroom. The yellow one is for “recyclable waste” while the black one is for“unrecyclable waste”.
Recycling helps a lot in protecting the environment. Take your pen for an example. 5.At the recycling factory, its metal parts could be used to make other things. But recycling is not enough. “The best thing to do is just keep using your stuff for as long as you can,” US writer Adam Minter told Time Out magazine.
