1 . Today we know Antarctica as an extreme environment containing ice and snow. But new research provides evidence that the area had a rainforest in the past.
The researchers collected a piece of Earth sediment (沉淀物) from under the seafloor off the coast of Antarctica. In the sediment they discovered forest material that was estimated to be about 90 million years old. This would have been in the Cretaceous Period, when dinosaurs were the main land animals. The sediment was removed by scientists on the research icebreaker RV Polarstern in the Amundsen Sea near Pine Island Glacier.
Johann Klages is a geologist with the Alfred Wegener Institute, Helmholtz Center for Polar and Marine Research in Germany. He was the lead writer of a study on the findings, published in the journal Nature. He said the sediment was collected from a depth of about 30 meters below the ocean floor. Klages said an examination showed that the material didn’t form in the ocean.
The researchers estimate that the area—about 900 kilometers from the South Pole—had average yearly temperatures of about 12 to 13 degrees Celsius. During the warmest summer months, average temperatures likely reached between 20 and 25 degrees Celsius. The soil included fine dirt particles (颗粒) and hard clay, as well as substances linked to at least 65 different kinds of plants, the study found. Klages added that the plants included trees, ferns and flowering plants. While no animal remains were found, Klages said there were likely dinosaurs, flying reptiles (爬行动物) and many insects in the environment.
The research represents new evidence of the major climate changes Earth has experienced in the past—and is currently undergoing today. The soil in the sediment dates back to the planet’s warmest period of the past 140 million years, with sea level about 170 meters higher than today. The researchers said that the rainforest environment in Antarctica was especially surprising because each year, the area experiences a four-month polar night when there is no sunlight to fuel plant life. Klages said no ice sheets were present during the time, but seasonal snowfall was likely.

2 . A flock of wild mandarin ducks(鸳鸯) are the biggest draw in the West Lake scenic area in Hangzhou, capital of East China's Zhejiang province, with tourists flocking from around the country to see them. However, some of the tourists have been feeding the ducks, even pulling them by the neck to force-feed them. On Monday, a video claiming that some of the ducks had died from over-feeding went viral on social networking sites.
Although there are prominent signboards warning people against feeding them, tourists just cannot hold back. Some even believe the ducks are underfed and they are doing them a favor, little realizing that their action can be detrimental to the birds' health.
Human food does not always go down well with ducks, particularly potato chips, as the oily snack can damage the health of mandarin ducks. However, tourists can frequently be seen feeding the ducks food that the birds cannot digest. Besides, feeding the ducks could stop them from competing in the wild to find their food. If they become dependent on food provided by humans, they will lose their survival skills. Also, by giving food to them, the tourists are polluting the environment. Especially, food thrown into the water could harm the ecosystem there.
However, the tourists know little about the harm they cause to the environment and there is a need to create awareness about it. Meanwhile, the number of mandarin ducks at West Lake has dropped from 336 last year to 260 this year. Maybe the declining numbers will wake the tourists up to this reality.

3 . James T.Green thought he was having a panic attack.
He took a break from work to walk around the block during a stressful day, and noticed he felt out of breath walking up a slight slope."This isn't normal,” Green thought.He had become a regular biker in recent months and wasn't exactly out of shape.He sat down at his desk, and looked at the Apple Watch on his wrist.His heart rate was through the roof, and the Heart Watch app he was using to check his pulse （脉搏）was flashing warnings.Maybe it was something more serious, he thought.
Although he had blood clots （血栓）in his lungs a few years back, he had been taking medication, and doctors said that it was an unusual condition for someone in their mid-20s.Still, the symptoms （症 状）this time were much less serious, and he was feeling stressed, so his mind didn't automatically jump to blood clots.Green's doctor told him it sounded like anxiety.But then he showed her his heart rate recorded by the Apple Watch.
"This is my normal heart rate,” Green told her, pointing to the graph in the app.“This is where my heart is now.There's something wrong."
The doctor ordered a CT scan.The blood clots in his left lung had returned.An ambulance rushed Green to the emergency room, where he was pumped full of blood thinners.He didn't need surgery this time, but doctors told him that if he had waited, a clot could have killed him.
Green isn't the only person who has discovered a serious health condition after seeing heart-rate data on a smartwatch.And he won't be the last.Presently, smartwatches from Apple to Fitbit and others can tell you your heart rate and track your workouts.But these companies want to go beyond the basics by developing ways to tell you when something is wrong.In fact, it's already happening.
1. What is not normal for Green this time?| A．He breathed with difficulty. | B．He worked out less often. |
| C．He had a heart attack. | D．He was out of shape. |
| A．He himself. | B．His doctor. | C．The CT scan. | D．The Apple Watch. |

4 . The great 18th-century author Montesquieu once put it, “I have never known any stress that an hour’s reading does not reduce." And now many argue for a return to this view of literature as therapy, even using the word “bibliotherapy"（阅读疗法）to describe it.
So what does literature provide, beyond entertainment? It can act as a guide.Those who show great respect for Shakespeare, Milton or Proust should keep in mind that even the most famous author was still a human being.In other words, great writers have been through the same things as you.Like you, they found themselves in this strange world and they tried to make sense of it.And this is what most literature consists of: people trying to make sense of the world.
No matter what your fears or concerns may be, chances are some great writer has written about them.Before seeking （寻求）suggestions, cither from a professional or a well-read friend, be clear about what is troubling you.For example, let's say you were raised in a religious （信仰宗教的）family but now, in later life, have lost your faith （信仰）.This is painful to you and you feel empty and alone.Countless writers have gone down this path before you and have found a way out — the German poet and novelist Hermann Hesse, for example, wrote the wonderful little novel Siddartha about this search for spiritual peace.
It would also help to consider your particular life stage.Someone from a poor background about to set off for a great college will want a different set of reading from a retired woman whose husband has died.To take another example, let's imagine you had a childhood of abuse （虐待）.For years you have suffered from depression.In that case, you could try Edward St Aubyn's The Patrick Melrose Novels.St Aubyn's father abused him, while his mother escaped into drink, but Aubyn wrote a series of splendid novels based on his life, charting a man's journey through the hard situation of abuse and out the other end.

5 . A boy was dying of terminal leukemia (白血病). His mother took his hand and asked, “Bopsy, did you ever think about what you wanted to be when you grew up?”
“Mommy, I always wanted to be a fireman when I grew up.”
Later that day she went to the fire department, where she met Fireman Bob. She explained her son’s final wish and asked if it might be possible to give her six-year-old son a ride around the block on a fire engine. Fireman Bob said, “Look, we can do better than that. We’ll make him an honorary fireman for the whole day. He can come down to the fire station, eat with us, go out on all the fire calls, the whole nine yards! And, we’ll get a real fire uniform made for him.”
Three days later Fireman Bob picked up Bopsy, dressed him in his fire uniform and escorted (护送) him from his hospital bed to the waiting hook and ladder truck. Bopsy was in heaven. Having his dream come true, with all the love and attention that was lavished (慷慨给予) upon him, Bopsy lived three months longer than any doctor thought possible.
One night all of his vital signs began to drop and the head nurse called the fire chief and asked if it would be possible to send a fireman in uniform to the hospital to be with Bopsy as he made his transition. The chief replied, “We can do better than that. We’ll be there in five minutes. Will you please do me a favor? When you hear the sirens (警报器) screaming and see the lights flashing, will you announce over the PA system that it’s just the fire department coming to see one of its finest members one more time? And will you open the window to his room?”
About five minutes later a hook and ladder truck arrived at the hospital, extended its ladder up to Bopsy’s third floor open window and 14 firemen and two fire-women climbed up the ladder into Bopsy’s room. They hugged him and held him and told him how much they loved him. With his dying breath, Bopsy looked up at the fire chief and said, “Chief, am I really a fireman now?”
With those words, Bopsy smiled and closed his eyes for the last time.

6 . Everyone needs friends.There is an old saying, "Friends are God’s way of taking care of us." But how do you find real friendship and keep it?
The American writer Sally Seamans tells young students some smart ways to make friends.Sally says finding friendship is just like planting a tree.You plant the seed(种子)and take care of it to make it grow.
First, you should choose a friend.What makes a good friend? It is not because a person has money or good looks.A good friend should be kind and patient(耐心).For example, if you have a bad day, a good friend should listen to your complaints and do his best to help.To make a good friend, you cannot be too shy.You should make each other happy and share your lives.
But things cannot always be happy.Even the best friends have fights.What should you do when you have a fight with your friend? You have to talk to him or her.When there is no one around, have an honest talk.If he or she doesn't want to talk, you could write a letter.
There are three steps to being friends again:
Tell him or her how you are feeling; say what your friend has done wrong, and explain why you did this or that.Remember that friendship is the most important thing in your life.

7 . When I was a kid, my siblings (兄弟姐妹) and I used to have ice cream for dessert. Every day, we would choose which ice cream flavor to have, whether to eat it in a cone or a bowl. Then we would happily wolf down our treat (款待) as fast as we could.
Once, though, when I was probably about 10 or 11, our grandpa came to visit us. Grandpa always had a unique view on things. On this particular occasion, my sister and I were making bets as to who could finish our ice cream first. With a smile, Grandpa said, “Why would you want to finish first? If you eat slowly, it will last longer. You should have a competition to see who can finish last.” Even now, I always try to taste my ice cream, but of course this is about more than just dessert.
Too often, kids want to scramble (争夺) for more, whether it’s more ice cream, more toys, or more friends. This habit persists into our adult years, and we end up constantly scrambling for more. We never develop the skill of appreciating what we have. If we learn to recognize this pattern and change it, we can raise our kids a little differently, giving them the tool of tasting their widely known dessert, which could lead to a happier life for them.
What my grandpa taught me that day was really that if you take the opportunity to enjoy what’s in front of you, the pleasure will last longer and be more rewarding than if you rush through life always trying to get the next treat. It’s a lesson that, I think, has made my adult life happier, as well. These days, when I want something, I wait as long as I can before I allow myself to have it. Then, when I finally get it, I make sure to treasure it as long as possible, because I know that, no matter what it is, it will be gone all too soon.

8 . It is important to protect yourself from harmful rays. But if you think a high-factor sunscreen keeps you safe from harmful rays, you may be wrong. Research in this week’s Nature shows that while factor 50 reduces the number of melanomas(黑素瘤)and delays their occurrence, it can’t prevent them. Melanomas are the most aggressive skin cancers. You have a higher risk if you have red or blond hair, fair skin, blue or green eyes, or sunburn easily, or if a close relative has had one. Melanomas are more common if you have periodic intense exposure to the sun. Other skin cancers are increasingly likely with long-term exposure.
There is continuing debate as to how effective sunscreen is in reducing melanomas—the evidence is weaker than it is for preventing other types of skin cancer. A 2011 Australian study of 1,621 people found that people randomly selected to apply sunscreen daily had half the rate of melanomas of people who used cream as needed. A second study, comparing 1,167 people with melanomas to 1,101 who didn’t have the cancer, found that using sunscreen routinely, alongside other protection such as hats, long sleeves or staying in the shade, did give some protection. This study said other forms of sun protection—no sunscreen—seemed most beneficial. The study relied on people remembering what they had done over each decade of their lives, so it’s not entirely reliable. But it seems reasonable to think sunscreen gives people a false sense of security in the sun.
Many people also don’t use sunscreen properly applying insufficient amounts, failing to reapply after a couple of hours and staying in the sun too long. It is sunburn that is most worrying—recent research shows five episodes of sunburn in the teenage years increase the risk of all skin cancers.
The good news is that a combination of sunscreen and covering up can reduce melanoma rates, as shown by Australian figures from their slip-slop-slap campaign. So if there is a heat wave this summer, it would be best for us, too, to slip on a shirt, use sunscreen and slap on a hat.

9 . The African grey parrot’s ability to talk and mimic sounds makes it a charming companion. African grey owners often report that their greys oftentimes talk in context and can understand their people’s emotions (情感). The African grey parrot is not just a top talker - this bird is also known for its extreme intelligence, which gives them the name “The Einsteins of the Bird World”.
The bird is medium-sized, dusty-looking and almost pigeon-like. It has a bright red tail, intelligent orange eyes, and a stunning scalloped (扇形的) pattern to its feathers. Their diet in the wild consists mostly of nuts, seeds, fruits, and leafy matter.
At home, African greys need plenty of toys that challenge their intelligence, such as food searching and puzzle toys. Nutri-Berries by Lafeber Company are a perfect choice, which, with a balance of grains, seeds and other nutrients in the shape of a berry, encourages African greys to hold, bite off, and even play with, just as they do in the wild.
African greys seem especially affected by stress and disturbing noise in their environment and can be put more at ease by placing one corner of the cage against a wall as opposed to in the middle of a room.
African grey parrots are more likely to suffer from lack of Vitamin-A/beta-carotene, and therefore benefit from eating vegetables high in beta-carotene, such as cooked sweet potato and fresh kale. Lack of Vitamin-D is another concern, especially for greys on a poor diet. Offering a balanced, pill-shaped diet, such as Nutri-Berries, helps prevent vitamin and mineral shortage.
