According to a new US study, couples who expect their children to look after them in old age should hope they have daughters because daughters are twice as attentive as sons overall.
The research by Angelina Grigoryeva, from Princeton University, found that, while women provide as much care for their elderly parents as they can manage, men do as little as they can get away with and often leave it to female family members.
Her analysis of the family networks of 26,000 older Americans concluded that gender(性别) is one of the most important things that decide whether or not people will actively care for their elderly parents.
In a paper presented at the annual conference of the American Sociological Association in San Francisco, she concludes that simply having a sister makes men likely provide less care.
Using data from the University of Michigan Health and Retirement Study, a study which has been tracking a crosssection of over50s for the last decade, she calculated that women provide an average of 12.3 hours a month of care for elderly parents while men offer only 5.6 hours.
“Sons reduce their relative caregiving efforts when they have a sister, while daughters increase theirs when they have a brother.”
“This suggests that sons pass on parent caregiving responsibilities to their sisters.”
In the UK, the 2011 Census showed that there are now around 6.5 million people with caring responsibilities, a figure which has risen by a tenth in a decade.
But many are doing so at the risk of their health.The census showed that those who provide 50 hours or more of care a week while trying to hold down a fulltime job are three times more likely to be struggling with ill health than their working counterparts who are not carers.

We must follow a different path to let our light shine, and that’s what makes us so unpredictable and unique. In today’s world, expecting every child’s education to be the same, progress at the same rate and be measured against the narrow standards of performances is not just outdated, it’s also harmful to young people.
I experienced this disconnect(脱节) firsthand after graduating from college. I had many opportunities in front of me, but they didn’t test my limits and my creativity to pursue my passions. At first, I took a job at a big consulting firm. However, I couldn’t shake my passion for music. I had followed the somewhat predictable path of a college graduate, but I was crazy about how to become an artist. Now I am a nine-time Grammy Awards winner who has sold multiple Top 10 Albums.
Imagine what it would look like if our schools were set up to help people discover and pursue a personal passion instead of a predictable path? The good news is that a number of individuals and organizations are finding new ways to innovate in education. The goal is to create more student-centered environments that help young people not just do better in school but also discover what they love.
We can’t live lives of joy if we can’t discover what we love doing with our lives. So let each person discover the power and uniqueness of his or her own passion.

【推荐2】Throughout life, we come across many people who impact us in a way. The person who left a great impact on me is my dad.
Three months after turning fourteen, my life was great. I was getting settled into a high school; my grades were already starting off greatly and I was making friends. One day as I came home from school, I walked into our living room, finding my mom and dad talking. My parents turned to me and told me to sit down because there was something important they had to tell me. I soon found out that my dad’s liver (肝脏) was failing and he needed an immediate transplant. I was shocked and confused. He was working and never looked sick. My parents told me not to worry because everything would be fine. Four months had passed and my dad still had not received a new liver; he was progressively getting worse. His body seemed to be getting weaker, but he constantly said he was fine.
It was getting hard for my family and me. My dad had to quit his job leaving my mom to be the only provider. I had to take on the responsibility of cleaning the house, cooking meals and checking on my dad while my mom was at work. I had to cut back on hanging with my friends because my dad was beginning to go in and out of the hospital. My focus for school was starting to slip. So were my grades. Two nights before my school spring break, my mom received a call from the hospital that my dad had been in a car accident and that he was in hospital. Surprisingly, my dad hadn’t received a scratch on him. Then next night my mom received a call from the doctor stating that there was a liver that matched my dad’s body and that he needed to get to the hospital immediately.
My mom and I rushed to the hospital and my dad was brought into surgery. We were waiting anxiously outside. After what seemed to be a long time, his doctor came out and informed us that the surgery was successful, but my daddy couldn’t leave the hospital for at least a month. During my daddy stay in the hospital and his adapting to his new liver, my father still tried to comfort us, saying that everything would be OK.
Having to take on so many responsibility at home and constantly worrying about my daddy have helped shape me into the person I am today. I become more responsible for my family and even for everything. Seeing my daddy remain positive and strong throughout his journey has taught me not to take my life for granted, but still positive about life. Also, having seen my dad in hospital for months has inspired me to go into the medical field as a doctor. Thus, I can do everything in my power to help those in need.

【推荐3】Grandparents Answer a Call
As a third generation native of Brownsville, Texas, Mildred Garza never pleased move away. Even when her daughter and son asked her to move to San Antonio to help their children, she politely refused. Only after a year of friendly discussion did Ms. Gaf finally say yes. That was four years ago. Today all three generations regard the move to a success, giving them a closer relationship than they would have had in separate cities.
No statistics show the number of grandparents like Garza who are moving closer to the children and grandchildren. Yet there is evidence suggesting that the trend is growing. Even President Obama’s mother-in-law, Marian Robinson, has agreed to leave Chicago and into the White House to help care for her granddaughters. According to a study grandparents com. 83 percent of the people said Mrs. Robinson ‘s decision will influence the grandparents in the American family. Two-thirds believe more families will follow the example of Obama’s family.
“In the 1960s we were all a little wild and couldn’t get away from home far enough fast enough to prove we could do it on our own,” says Christine Crosby, publisher of Grate magazine for grandparents. We now realize how important family is and how important to be near them, especially when you’re raining children.”
Moving is not for everyone. Almost every grandparent wants to be with his or her grandchildren and is willing to make sacrifices, but sometimes it is wiser to say no and visit frequently instead. Having your grandchildren far away is hard, especially knowing your adult child is struggling, but giving up the life you know may be harder.

【推荐1】In 1803, the United States acquired a huge new piece of land called the Louisiana Territory. Meriwether Lewis and William Clark were given the job of leading an expedition to collect data about this uncharted territory. President Thomas Jefferson gave Lewis and Clark three tasks for the journey: Find an all-water route to the Pacific Ocean, make friends with the Native Americans along the way, and gather detailed information about the plants, animals, landforms (地形), and climate of the area.
In order to discover if there was an all-water route to the Pacific Ocean, Lewis and Clark attempted to travel up the Mississippi River by boat. In this way, they hoped that they would eventually reach the Pacific. Ultimately, the explorers discovered the Rocky Mountains and the Continental Divide, but not the Pacific Ocean. The hope for an all-water route from the East to the Pacific would have to be abandoned.
Lewis and Clark’s second task was to make friends with Native Americans in the area. They packed hundreds of pounds of gifts for the indigenous people, including beads, sewing needles, cloth, yarn, and knives. Their intention was to use these items as offerings of peace and good faith. However, many tribes were hostile. They felt threatened by the Americans’ presence and refused to communicate with them. Other tribes were more welcoming and aided the explorers in finding food and navigating the new region.
The explorers’ final task was extensive and ongoing. Lewis and Clark had to take detailed notes about the landforms and climate of the different areas through which they travelled. President Jefferson also wanted samples of notable plant and animal life. They prepared animal fur and plant samples to send back to the president throughout the trip. They also kept individual journals with detailed descriptions and drawings of the environment and terrain (地势).
Up the Mississippi and Missouri rivers, across the Great Plains, over the Rockies, down the Columbia River, and to the Pacific Ocean, Lewis and Clark travelled. After 3 years, Jefferson received a letter from Lewis stating, “It is with great pleasure that I announced to you the safe arrival of myself and my partner. In obedience to your orders, we have penetrated (穿过)the continent of North America to the Pacific Ocean.”

【推荐3】Teenagers from low-income families in particular are more likely than their middle-class peers 同龄人)to do less well in schoolwork and to drop out of school. Studies have shown, however, that a positive attitude towards schoolwork and the support and encouragement from their parents can help at-risk youngsters to overcome the economic barriers(障碍) and lack of resources they face. Most of the evidence about the effects of parental involvement(参与) comes from research on mothers. Little is known, however, about how teenagers experience their fathers, warmth and the beliefs and behavior that are most affected by it.
This new study is part of a large one focusing on low-income families conducted in four middle schools in the southwestern United States. Researchers asked 183 sixth-graders about how optimistic and motivated they were about their school work, and how they experienced their fathers’ warmth. The students’ maths and language arts grades were also gained. The research team took into account the influence that mothers have on their children’s well-being in their analyses.
Their findings show how fathers can support their teenagers in ways that result in greater optimism and higher achievement at school. “ Low-income fathers affect their teenagers’ beliefs about themselves and their future, and these beliefs influence their achievement by increasing their determination to accomplish school tasks,” says Dr, Marie-Anne.
These positive effects extend(延伸) to both sons and daughters, although in different ways. Experiencing their fathers’ warmth first influences daughters’ sense of optimism, and then spills over into their feeling more determined and certain about their academic abilities. This in turn leads to better maths grades. There is a more direct link between their fathers’ love and boys’ belief in their ability to succeed in academy.

【推荐1】At Serious Readers we understand that the creative mind requires many factors to function properly.
Creativity and inspiration can often strike when we least expent it, and disappear rapidly when we feel we most need it. Inspiration demands attention, at any hour of the day; that’s why Serious Lights use a special technology that allows us to closely replicate (模拟) natural daylight and bring it indoors. This means that wherever you are, and whatever time it is, you can write like you are bathed in a pool of natural sunshine.
“Read a thousand books, and your words will flow like a river.”— Lisa See
Every author will tell you that the key to becoming a skilled writer is to devote yourself to reading. Reading develops your vocabulary, teaches you narrative structure, and provides a window to worldviews beyond your own. Time spent in front of a page is important for any hopeful wordsmith, and the longer you read, the better prepared you are to write. But many people struggle with reading for long periods of time. They experience blurred vision, headaches, hard concentrating and sore or dry eyes. These are symptoms of what is commonly known as eyestrain (视疲劳). A Serious Light works with your eyes to reduce these symptoms and allow you the freedom to read and write for as long as you desire.
“A writer is a world trapped in a person.”— Victor Hugo
Books often provide us with a sense of freedom. The common phrase “get lost in a book” indicates the sensation of allowing the world around you to fade away while the words on the page become a world inside your head. That feeling of freedom shouldn’t be hampered by tired and sore eyes. Most readers spend the majority of their time under some form of artificial light. This is where the problem starts. Most artificial light sources are not designed with your eyes in mind and will cause your eyes to overstrain and become tired and annoyed much faster. With a Serious Light you will experience sharper text, vivid colour, and breathtaking clarity, allowing you to read and write for as long as you desire.

【推荐2】Every day in the United States animals are beaten, ignored, or forced to struggle for survival. Left in poor conditions with no food or water, they have little hope as they live out their days without the mercy they deserve. Some are found and rescued, given the chance to experience how great life and humans can be; others aren't so lucky. To grow as a nation, we must fight for these abused(受虐待的) animals’ rights and seriously punish heartless owners.
One of the first steps in protecting animals and creating effective cruelty laws is to know what animal cruelty actually is. There are two categories: passive cruelty and active cruelty. The first involves acts of omission, meaning the abuse happens as a result of ignorance or lack of action. Passive cruelty might seem less serious, but that is not the case; it can lead to terrible pain and suffering, and finally death. Examples include starvation, inadequate shelter in extreme weather conditions, and the failure to get medical care. Passive cruelty is sometimes due to the owner's ignorance, so many animal control officers will first try to educate ignorant owners on how to properly care for animals before giving them a citation(传票) or putting them in prison.
Active cruelty, on the other hand, is more well-known and disturbing. Sometimes referred to as non-accidental injury, this type of abuse involves purposeful harm on an animal in order to feel more powerful or gain control. Active cruelty against animals should be taken very seriously, since it can be a sign that a person has serious psychological issues and may commit more acts of violence---possibly against humans.
It is hard to tell just what drives people to harm innocent animals. Most animal abusers find some sort of achievement or power in torturing a victim that they know can't fight back. While not all animal abusers become serial killers, it is important to take every case seriously.
As a nation we need to make it our right to come together and ensure the safety of our beloved pets. As Margaret Mead once said, “Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it is the only thing that ever has.”
1. What is the first step to do with the passive cruelty abusers?| A．To throw them into prison. | B．To bring the case to the court. |
| C．To teach them how to treat animals. | D．To give them a strong warning. |
| A．is actually a sign of power or control |

【推荐3】A complete chicken egg estimated to be around 1,700 years old is believed to be the only of its type in the world, after scientists found it still had liquid inside.
It was discovered during a dig in Aylesbury in Buckinghamshire between 2007 and 2016, with researchers saying at the time that it was a “genuinely unique discovery”. During the course of the dig, archaeologists broke three other eggs which released a “terrible smell”, but a fourth egg remained undamaged. It is the only complete egg ever found dating back to the Roman times.
Now, a micro scan has found that the egg still contains the yolk (蛋黄) and egg white, and it is believed to be the only complete egg from that period. The recent work has been carried out by conservator Dana Goodburn-Brown, who took the egg for further analysis at the University of Kent.
Edward Biddulph, senior project manager at Oxford Archaeology, who oversaw the dig, said, “It produced an amazing image that indicated that the egg, apart from being complete — which is incredible enough — also held its liquid inside. We were absolutely blown away when we saw the contents in there, as we might have expected them to have leaked out.”
It has also been taken to London’s Natural History Museum, where Douglas Russell, the senior director of the museum, was consulted about how to conserve the egg. Mr Biddulph said, “As we found out when we visited the Natural History Museum, it appears to be the oldest known example in the world.”
The egg is now being housed at Discover Bucks Museum in Aylesbury while work continues to discover how to extract (提取) the inside without breaking the delicate shell.
“There is huge potential for further research and this is the next stage in the life of this remarkable egg,” Mr Biddulph said.

【推荐1】If it really is what’s on the inside that counts, then a lot of thin people might be in trouble.
Some doctors now think that the internal fat surrounding important organs like the heart liver could be as dangerous as the external fat which can be noticed more easily.
“Being thin doesn’t surely mean you are not fat”, said Dr Jimmy Bell at Imperial College.
Since 1994, Bell and his team have scanned nearly 800 people with MRI machines to create “fat maps” showing where people store fat.
According to the result, people who keep their weight through diet rather than exercise are likely to have major deposits of internal fat, even if they are slim.
Even people with normal Body Mass Index scores can have surprising levels of fat deposits inside. Of the women, as many as 45 percent of those with normal BMI scores (20 to 25) actually had too high levels of internal fat. Among men, the percentage was nearly 60 percent.
According to Bell, people who are fat on the inside are actually on the edge of being fat. They eat too many fatty and sugary foods, but they are not eating enough to be fat. Scientists believe we naturally store fat around the belly first, but at some point, the body may start storing it elsewhere.
Doctors are unsure about the exact dangers of internal fat, but some think it has something to do with heart disease and diabetes (糖尿病). They want to prove that internal fat damages the body's communication systems.
The good news is that internal fat can be easily burned off through exercise or even by improving your diet. “If you want to be healthy, there is no shortcut. Exercise has to be an important part of your lifestyle,” Bell said.

The term “crocodile tears” refers to insincere sadness. This term has an etymology dating back several centuries. As early as the fourth century, crocodile tears are referenced in the literature with the meaning of insincere sorrow. It is said that crocodiles weep while eating their hunted animals because they are sad; however, this sadness is not honest.
The term crocodile tears became widely popular after it was documented in a fifteenth-century book titled The Voyage and Travel of Sir John Mandeville, Knight. A passage from the book reads: “These crocodiles kill men and they eat them weeping.”
As you may already know, crocodilians(鳄目动物) likely feel bad about little—especially feeding. However, the assumption of the crocodile-tears metaphor may be true. In a 2007 paper published in BioScience titled “Crocodile Tears: And they eat them weeping”, researchers observed 7 crocodilians in cages during feeding time at a reserve (4 caimans and 3 American alligators). The researchers observed the crocodilians outside of water at feeding stations to better find out whether tearing developed.
Five of the 7 crocodilians developed something like tears in their eyes before, during or after feeding. The researchers suggest that these crocodile tears occur because a crocodilian hisses (发出嘶嘶声) while it eats, and this hissing forces air through the spaces in the bone behind the nose and out the eye, in the process picking up nasolacrimal secretions (鼻泪管分泌物.)
In humans, crocodile tears is a medical condition that causes a person to tear up while eating. Crocodile tears typically occur because of a temporary loss of facial control due to damage of the facial nerve. Specifically, when the facial nerve grows again, it does so incorrectly thus resulting in tears during chewing food.
