Patsy Smith has raised ducks for many years. One of her ducks, Peg, losing one of his legs from a fight with a tortoise. Mrs. Smith calls for help to see if anyone could create new leg for Peg. Three students thought they would probable use their 3D printer to create a leg for him! They spent several months creating and testing different model. It turned out to be a lot more difficult than they had thought! Luckily, their hard work was paid off and they created a model who fitted Peg's leg perfectly! Now, Peg can walk or even run just like her duck partners! And Mrs. Smith is very thankful for them.

Fishing is a great family sport，and a fun summertime activity. 1.. If you have never fished before it can seem very complicated. Expert fishers know when and where to find certain fish and the best technique to catch each fish. Expert knowledge comes from years of experience.2..
As a beginner you will want to use a technique called“Bait(鱼饵)Fishing”. This type of fishing is probably the easiest technique for catching fish. You will need some basic fishing equipment，which you can get at almost any outdoor gear store. You will have to have a rod and fishing line，hooks，some bait and if you are planning on keeping the fish，you will need something to store the fish.
The best way to learn how to fish is to learn from someone who already knows，so when planning your fishing trip，be sure to bring along someone who has fished before. 3.，you will need to decide where to go fishing. Probably for the first time you will want to go to a local lake，where the water is calm and there are plenty of fish. You should also try to research the different types of fish that live in the place you decide to fish，so you know what types of bait they like to eat and what you want to do with the fish once you have caught it.
4.，you probably want to clean the fish，then store it before continuing fishing. If you want to release the fish，be extra careful when removing the hook，so it doesn’t get hurt too badly，then gently hold the fish in the water and allow it to swim away out of your hands.
5. Take some time to learn from an expert and you will be able to catch all types of fish using a wide variety of methods.
A.If you want to keep the fish
B.After you have decided to go fishing
C.Once your hook and bait is in the water
D.Now you have a very basic understanding of fishing
E.There are many different species of fish and types of fishing
F.Here are a few simple and basic fishing tips to get you started
G.At this point you will need to determine if you want to keep the fish
A new device works like a solar panel，except that it doesn’t harvest energy from the sun. It absorbs energy from the cold night sky.
A prototype(原型)of the device produced enough electricity at night to power a small light bulb. A bigger version might one day light rooms or charge phones. It also could power electronics in remote or low-resource areas that lack electricity.
The device makes use of the temperature difference between Earth and outer space. It then uses that difference to create electricity. As long as one side of it is cooler than the other，the generator can produce electricity. The cooler side faces the sky and is attached to an aluminum plate. That plate is sealed beneath a transparent cover and surrounded with insulation(隔热材料) to keep out heat. The bottom of the generator is attached to an exposed aluminum plate. That plate is warmed by the local air. At night，the top plate can get a couple of degrees Celsius cooler than the bottom of the generator.
Researchers tested a 20-centimeter prototype one clear December night in Stanford，California. The generator produced up to about 25 milliwatts of power per square meter of device. That was enough power to light a small light-emitting diode，or LED bulb. Further improvements might increase its production to at least 500 milliwatts per square meter. To do that，the system might need more insulation around the cool top plate.
The device also could help power remote weather stations or other environmental devices，says Aaswath Raman. He is a materials scientist who worked on the device at the University of California，Los Angeles. This may be useful in polar regions that don’t see sunlight for months at a time，Raman says. “If you have some low-power load and you need to power it through three months of darkness，this might be a way. ”
