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. ”
1.What can we know about the new device?
A.It gains energy from the sun. B.It’s been widely used in life.
C.It is cooler than a solar panel. D.It’ll be popular in special areas.
2.What does the author mainly talk about in Paragraph 3?
A.Application fields of the device.
B.The developing process of the device.
C.The working principle of the device.
D.Significant effects of the device.
3.How can the device produce more electricity?
A.By putting more insulation around the top plate.
B.By using it in extremely cold and clear nights.
C.By attaching the bottom plate to a warm plate.
D.By covering the top plate with a transparent lid.
4.What could be a suitable title for the text?
A.A Device Using the Cold Night Sky to Produce Electricity
B.A Device Bringing New Hope for Those in the Cold Night
C.The Difference Between a Solar Panel and a New Device
D.The Temperature Difference Between Earth and Outer Space
Sam is a fourth-year student at Harvard Medical School，but poetry is still a big part of his life，now with a new teacher，Rafael Campo，who believes poetry can benefit every doctor’s education and work. Rafael is a physician，professor and a highly respected poet.
“Poetry is in every encounter(邂逅)with my patients. I think healing is really in a very great way about poetry. And if we do anything when we’re with our patients，we’re really immersing(使沉浸于)ourselves in their stories，really hearing their voices. And，certainly，that’s what a poem does，”he said.
Rafael worries that something important has been lost in medicine and medical education today：humanity，which he finds in poetry. To end that，he leads a weekly reading and writing workshop for medical students and residents(住院医生).
He thinks medical training focuses too much on distancing the doctor from his or her patients，and poems can help close that gap.
Third-year resident Andrea Schwartz was one of the workshop regulars. She said. “I think there’s no other profession other than medicine that produces as many writers as it does. And I think that is because there’s just so much power in doctors and patients interacting when patients are at their saddest. ”Not everyone believes that’s what doctors should do，though.
Rafael said，“I was afraid of how people might judge me，actually. In the medical profession，as many people know，we must always put the emergency first. But，you know，that kind of treatment，if it’s happening in the hospital，very regrettably，sadly，results in a bad outcome. The family is sitting by the bedside. The patient hasn’t survived the cancer. Don’t we still have a role as healers there?”
In a poem titled“Health”，Rafael writes of the wish to live forever in a world made painless by our incurable joy. He says he will continue teaching students，helping patients and writing poems，his own brand of medicine.

B.The effect of poetry in medical treatment.

3.What does Andrea Schwaflz think of poetry?
A.It comforts patients’family.
B.It contributes to medical work.
C.It has nothing to do with doctors.
D.It keeps doctors away from patients.
4.What is Rafael Campo’s view on poetry?
A.It requires a lot of spare time.
B.It can provide a useful tool for doctors.
C.It has little effect on patients’conditions.
D.It should be included in emergency treatments.
When the young donkey Daisy May came to us，she was pregnant. With no donkey experience. I was unprepared for what might come next.
After some difficulty，Daisy’s baby was born. I thought the poor thing was dead. I planned to put the loss behind us and make sure she never got pregnant again. Just then，I heard a little noise. I couldn’t believe that baby was breathing and looking at me!We called him Samson，and of course I became his mother as much as Daisy was.
When Samson was nine months old，I had to separate Daisy and Samson for a few hours a day to wean(使断奶)him，but otherwise he went wherever she did. I think she would be lost without him. His donkey stepdad Bernard taught him to always be ready to have fun. They enjoy playing football together and going for a roll on a hot summer day.
I asked a worker to make a harness(马具)for my three little donkeys. When I brought it home I taught them one by one how to pull a cart. Samson watched and freely followed Daisy. When he was three，I put the harnness on him and he knew exactly what to do.
That was 15 years ago. Now，the most exciting thing about Samson is that he has become a little renowned. People come from all over to see him perform. The neighbors bring their grandchildren，and my sons bring their friends.
Samson shakes hands，unties my shoe，picks up a hat and more. And when I ask him if he has any bad habits，he tries to pick my pocket!He surprisingly learned these tricks himself. I just ask him to do them and he understands.
