Sending packets, shopping for everyday goods and even building a house, these are new skills that new robots show at the World Robot Exhibition.

    There are many online food shopping sites. Things l{#blank#}1{#/blank#}CDs, books, and DVDs sell well online. But it is quite different to sell food online because people like to see food with their o{#blank#}2{#/blank#} eyes. It is very I {#blank#}3{#/blank#} for people to buy fresh fruit and vegetables. Customers like to c{#blank#}4{#/blank#} their food by its color. They also want to touch and smell it. Some people like going to the same shop to buy food with good quality. So if the food is always g{#blank#}5{#/blank#}, they will feel comfortable buying it online.

    Boxes of fruits and vegetables have been d{#blank#}6{#/blank#} to homes around Britain for a few years now. Dried or canned foods are almost the same all the time, but fresh things are not. For example, People may want to pick their own apples so they can take the o{#blank#}7{#/blank#} that look nice. Buying dried and canned food online is easier. A person can buy this kind of food on the Internet and then buy fruits and vegetables at a store or a market.

Scientists say they recently invented the world's tiniest remote—controlled robots. The robots are small enough to sit on the side of a coin. They don't have any power of their own，and they can be controlled from a distance by using lasers（激光器）. The scientists say one day robots like these may be able to work in areas too small for tools. The robots don't move very quickly. But because of their tiny size，they're also not too slow. It takes the robots about 20 seconds to cover 1 centimeter. 

Right now the robots aren't all that useful. All they can do is to move，and they need to be in a place where lasers can shine on them to do that. But the scientists say these robots are an important step toward inventing more helpful tiny robots. 

The researchers say that one day tiny robots like these might be able to work in very small spaces. It's possible that they could build very tiny machines，or perhaps even travel inside the human body to help do with medical problems. 

Using similar building methods，the scientists made a number of different robots，including ones that looked like small insects. John Rodgers，says that their methods allow them to "build walking robots with almost any sizes or 3 D shapes. "

Here are the New Year's resolutions of my four friends.

My name is Dave and I am from the United Kingdom. I'm going to drink more water and less cola. I'm also going to brush my teeth before breakfast and after dinner, and wash my hands before eating.

My name is Tina and I am from the United States. I want to make more friends this year. I'm going to be nicer to the other children in my class. I'm going to be friendly to children who need friends－like someone who is shy or new to my school.

I'm Selina and I am from the United States. I'm going to work harder this year. I'm going to do all the homework that our teachers ask us to do. If I have any problems with my subjects, I'm going to ask my teachers for help.

My name is Toby and I am from Singapore. I'm never going to play computer games. When I feel angry or stressed, I'm going to find better ways to relax, like exercising, reading or discussing my problems with my friends.
