Holiday gift buying can feel a little empty, when all of those endless lists, long lines at the shopping center and dollars spent lead to a 5-minute excitement of flying wrapping paper. {#blank#}1{#/blank#} The following tips can help make gift giving more meaningful for both the giver and the receiver.

1 Know the person

    The most important thing in the exchanging of gifts is that it shows that you really know the person well, and you really care about him. {#blank#}2{#/blank#}

2 Donate in their name

    {#blank#}3{#/blank#} Research suggests that happier people give more to others, and that giving more makes people happier. Moreover, charity-related happiness is highest when people give in a way that promotes social connection. So, try giving to the less fortunate in someone's name this holiday season.

3 Give handmade goods or hand-me-downs

    {#blank#}4{#/blank#}  A study suggests that people feel that homemade items show more love, and love is what they want to express to the gift receiver.

    Family heirlooms(传家宝) may be another good gift option. A 2009 study found that when families hand down even a very depersonalized thing — money — to the generations, the symbolic value of the cash is greater than the numerical value alone.

4 Provide chances for participation

    If there's a golden rule of gifts, though, it's this: {#blank#}5{#/blank#} People who receive experiential gifts, such as concert tickets or a zoo membership, feel more connected to the gift giver than people who received material gifts.

A. Give experiences rather than objects.

B. But it doesn't have to be that way.

C. Giving gifts to friends or to charity is linked to happiness.

D. That is always beyond their expectation.

E. That means catering to another's pleasure.

F. Start listing every person you plan to give a holiday gift to.

G. The new and store-bought is not always best.

    As a father who works outside the home, I recognize that it is easy for me to get caught up in stress at work. Indeed, sometimes it is difficult to turn off my work focus and turn on my family focus so that I can come home and be the loving husband my wife needs and the playful father my kids want. {#blank#}1{#/blank#} Good fathers provide stability and strength to the family. As fathers, we do not let the pressures and worries of work get in the way of being there for our kids. {#blank#}2{#/blank#}

1）．{#blank#}3{#/blank#} It doesn't need to be a lot of time, but if you are able, have one­on­one time with each of your kids.

2）. Be goofy (滑稽的) with your kids. The more voices you do, the more expressive you are when you play with them, the more they will feel your love and your acceptance of them.

3）. Spend time reading to them. Allow your kids to choose a book and spend time reading some of it to them before bed. The more effort you put into it ,the more they will feel your love. {#blank#}4{#/blank#}

    As a therapist (临床医学家)  who works with children and their families, I have noticed that the better the relationship that a father has with his child, the more influence that father will have on his child. As fathers work on developing a strong link with their kids through positive interactions, they can have a positive effect on the lives of their children. {#blank#}5{#/blank#}

A．Fathers have such an important and irreplaceable role in the family.

B．Sometimes books can help you deal with children.

E．As a father he must involve hardships in all his life.

F．And the confidence can give their children a great advantage to succeed in the future.

G．Make a plan to spend time each day with your kids.

     Both men and women are living longer these days in industrialized countries. {#blank#}1{#/blank#} In general, they can expect to live six or seven years more than men. One reason for this is biological.

    One important biological factor that helps women live longer is the difference in hormones between men and women.{#blank#}2{#/blank#} Between the ages of about 12 and 50, women produce hormones that are involved in fertility(生育能力). These hormones also have a positive effect on the heart and blood flow. In fact, women are less likely to have high blood pressure or to die from heart attacks.

    {#blank#}3{#/blank#} They help the body defend itself against some kinds of infections. This means that women generally ger sick less often and less seriously than men. The common cold is a good example: women, on average, get fewer colds than men.

    {#blank#}4{#/blank#} Scientists are still not exactly sure how influence aging, but they believe that they do. Some think that a woman's body cells have a tendency(向) to age more slowly than a man's. Others think that a man's body cells have a tendency to age more quickly.{#blank#}5{#/blank#}

    Lost cities that have been found

    The White City

    In 2015, a team of explorers to Honduras in search of “the Lost City of the Monkey God” led to the discovery of the White City. They found the ruins in the Mosquitia region of the Central American country — which is known for poisonous snakes, vicious jaguars and deadly insects. It is believed that local people hid here when the Spanish conquerors(征服者)occupied their homeland in the 16th century.

    Canopus and Heracleion

    Modern researchers were teased by the ancient writings about the Egyptian cities Canopus and Heracleion — where Queen Cleopatra often visited. But the cities weren't found until 1992, when a search in Alexandria waters found that the two cities had been flooded for centuries. Artifacts(史前器物)showed that the cities once highly developed as a trade network, which helped researchers piece together more about the last queen of Egypt.

Machu Picchu

    A Yale professor discovered “the Lost City in the Clouds” in 1911. A combination palaces, plazas, temples and homes, Machu Picchu displays the Inca Empire at the height of its rule. The city, which was abandoned in the 16th century for unknown reasons, was hidden by the local people from the Spanish conquerors for centuries, keeping it so well preserved.

Troy

    The ancient city of Troy in Homer's The Iliad was considered a fictional setting for his characters to run wild. But in 1871, explorations in northwestern Turkey exposed nine ancient cities layered(层叠)on top of each other, the earliest dating back to about 5,000 years before. It was later determined that the sixth or seventh layer contained the lost city of Troy and that it was actually destroyed by an earthquake, not a wooden horse.

    Nola is a 41-year-old northern white rhino (犀牛) that lives at the San Diego Zoo Safari Park in Escondido, California. She is one of only four remaining northern white rhinos in the world, and the only one in the western part of the earth. The other three live in Kenya (肯尼亚).

    Rhinos have lived on earth for more than 40 million years, but they are now at the risk of dying out. Hunters illegally hunt rhinos for their horns (角), which are used for art, jewelry, and decorations. They sell the horns for thousands of dollars per pound, though it is not allowed by law. Rhino horns are also prized as a key part in traditional medicine, even though scientific tests have proven that the horns cannot cure illnesses. Experts say that every eight hours, one rhino will be hunted.

    Scientists are trying to find ways to prevent rhinos from dying out. In 1975, the San Diego Zoo Institute for Conservation Research started the Frozen Zoo, a program through which researchers have collected cell samples (细胞样品) from more than 8, 000 different animal species until now, including the northern white rhino. Scientists hope that by studying the rhino cells, they will gain greater understanding of the species, and will find ways to increase its number.

    Jeanne Loring works with the Frozen Zoo. Loring's research focuses on pluripotent stem cells, which are cells that can renew and become any cell type. Coloring's lab at TSRI is working together with scientist Oliver Ryder of the San Diego Zoo to use plenipotentiary stem cells to try to increase the number of the northern white rhino. Loring said the goal is to start producing new rhinos through this method over the next couple of years.

When we meet someone for the first time, we usually get a vague sense of what kind of person they are by the way they shake hands, talk, or walk. In the age of social networking, however, first impressions are sometimes made even before we actually meet someone in person—that is, by looking at their profile photo.

    According to a recent study, these social images say a lot about our personality. In the study, presented in a paper at the International AAAI Conference on Web and Social Media, a group of researchers from the University of Pennsylvania in the US used software to analyze the profile pictures of 66,000 users of US social platform Twitter and 3,200 of their tweets. At the same time, about 434 participants were asked to complete a survey about their personality type. The researchers wanted to find out if there was a connection between personality traits—like openness, extroversion, and neuroticism(神经质)—and a person's profile picture.

    According to the results, open people are more likely to pose in an unusual way and use objects such as glasses or a guitar in their profile photo because they enjoy new and exciting experiences. Meanwhile, neurotic people often hold back their negative emotions. They try to avoid showing their face；Instead, they use an image of something like a pet, a car or a building.

    Apart from the objects in profile pictures, the colors used in them also give us some hints about the photo's owner. For example, extraverts were found to have the most colorful profile images, as they want to emphasize their personality and show themselves off, the researchers wrote.

    Although social media photos "usually represent an extension of one's self, they also allow a user to shape his or her own personality and idealized view," according to the researchers. So, when choosing a profile photo, maybe we should ask ourselves first what kind of image we'd like to convey. After all, first impressions always last.
