Naturally, parents praise their kids. They want to encourage their children every day. But when it comes to building self-esteem (自尊) in children, praise doesn't always have a positive effect, according to a special edition of the journal Child Development. The issue, edited by Eddie and Thomas, is focused on research into how children develop a sense of self and building your child's confidence takes different skills than you might think.

    Eddie points out that children are born without a sense of self, but it doesn't take long before some kids have a lot of confidence and may feel superior to peers, while others may carry more self-doubt and see themselves as inferior. Yet no one really understands what causes children to view themselves the way they do. Surprisingly little is known about the origins of children's self-concept,” Eddie said.

    Research has found that when kids have a warm, loving relationship with their parents, they develop higher self-esteem. However, when they are given endless praise that is inequal to their achievements, their self-esteem may drop.

    Instead of lavish praise, parents should focus on warmth to build self-esteem, researchers have found—specifically, parents should show interest in their kids' activities and share joy with them. This makes children feel noticed and valued. According to Eddie's own research, children may develop lower self-esteem when their parents give them lots of positive and overstated praises. Too much praise can make children worry about disappointing their parents, and may lead to an unhealthy attitude toward failure. Other studies suggest that parents can teach children that failure is beneficial by encouraging kids to ask themselves: “Why didn't I achieve the result I wanted, and what can I do to change the outcome in the future?”

    Additionally, it's important for parents to encourage the belief that kids can develop basic abilities through devotion and hard work. Kids who are praised for their effort instead of their ability are more likely to develop a growth mindset, which have a positive impact on their confidence.

    Last year I was put into a lower­level math class at school. The reason I was in this class had nothing to do with my intellect (智力) or maths skills. I am blind.

The only problem with being in this class was that I was surrounded by “at­risk” students. These were kids who did not do well in school and they were constantly in trouble with the school and the law.

    One Tuesday morning, I went to a Christian Student Union meeting before school. There was a guest speaker there that day talking to us about praying (祈祷) for our enemies. I began to think about this. As I considered the idea, I prayed and asked God how I could pray for the kids in my class. I had forgotten that they weren't bad kids; they were just lost.

    At first, the prayers were mechanical. When I would hear their voices in class, I would pray, “Dear God, please bless so­and­so...” But as I continued, I began to think of the kids more often, and in my quiet time at home I would ask God to bless (保佑) the rest of my classmates.

    As time went on, my classmates became more than just annoying kids to me. There was something growing inside my heart for them, something that wasn't there before. They began to feel like family, and I was learning to love them in a way I never thought possible.

    I now see that praying is such a powerful act. Prayer is the most powerful tool a Christian has. When I pray for those around me, it also blesses my life, and it changes my opinion of others. I realized I needed God's blessings to see the world through loving eyes. The prayers I said for others turned out to help me the most.

    If all the food that's thrown away in three American cities could be saved, it would provide 68 million meals for people who don't have enough to eat, according to a recent study.

    The researchers found that, in the cities they surveyed（调查）, more than a kilogram of edible food per person is wasted each week. Edible food is food you can eat. It doesn't include things like apple cores（果核）, egg shells, or bones from meat. Fruits and vegetables were the most common edible foods found in the dustbin, followed by food leftover from meals. Eggs, bread and milk were also commonly thrown out.

    The people taking part in the survey gave several reasons for throwing edible food away. Most said the food went off. Some said they weren't interested in eating leftovers. A few said the food had passed the “Best Before” date printed on the label（标签）. When food is wasted—by families, restaurants or grocery stores—we are also wasting all of the resources that go into producing that food. That means we are wasting water, land, energy and labour, as well as the fuel needed to transport food.

    A lot of food is wasted before it even reaches the grocery store（食品杂货商）. Some food is damaged while it is being transported from the farm to the stores. Fruits and vegetables that don't look attractive enough don't even get put onto the shelves because most people won't buy them. Grocery stores, restaurants and hospitals also waste a large amount of food. The researchers suggest that grocery stores should donate any food that is still okay to eat to homeless shelters, instead of throwing it away. Prepared meals from hospitals or restaurants could also be donated to shelters.

Gift No. 1

    Offer to be your mother's health friend. Promise to be there for any and all doctor's visits whether a disease or a regular medical check-up. Most mothers always say "no need," but another set of eyes and ears is always a good idea at a doctor's visit. The best part? This one is free.

Gift No. 2

    Help your mother organize all of her medical records, which include the test results and medical information. Put them all in one place. Be sure to make a list of all of her medicines and what times she takes them. "Having all this information in one place could end up saving your mother's life," Dr. Marie Savard said.

Gift No. 3

    Enough sleep is connected to general health conditions. "Buy your mother cotton sheets（床单）and comfortable pillows to encourage better sleep," Savard said. "We know that good sleep is very important to our health."

Gift No. 4

Some gift companies such as Presents for Purpose allow you to pay it forward this Mother's Day by picking gifts in which 10 percent of the price you pay goes to a charity (慈善机构). Gift givers can choose from a wide variety of useful but inexpensive things —many of which are "green" — and then choose a meaningful charity from a list. When your mother gets the gift, she will be told that she has helped the chosen charity.

    My dad was in the Air Force. When I was a kid, we moved every few years. That meant a lot of good-byes. It also meant getting used to a whole new community and a whole new school each time we moved. I can still feel what it was like to have to walk into the new school—that sinking feeling in my belly, that heaviness in my throat. It would always take time for me to learn how everything worked, what was cool and what was not. It was always a struggle to find where I could fit in.

    Already shy, I didn't have much self-confidence in my friend-making abilities. I was the girl walking in the halls with her head down, panicking. When I spoke, you could hardly hear my soft voice. I was nervous and doubted myself a lot.

    It was very hard not having a history with everyone else. I was an outsider. But what I did have was soccer. Wherever I went, I knew that I could fit in with the soccer ball. The soccer team meant a familiar place and immediate friends for me. I could express myself and feel good about myself on the field. Playing hard helped to get rid of all my nervousness.

    Throughout our lives, our self-respect goes down when we feel like a failure, and it goes up when we feel successful. Doing something well, being praised, and feeling loved goes a long way. We all need to explore opportunities where we can be good at something and feel good about ourselves. Physical activity and sport participation is a terrific way to build up our sense of self-confidence and self-worth.

Lizzie's diary from Antarctica (南极洲)

Day 3: Tuesday   December 2

    We planned to go to Rothera that morning. We'd be staying there for the next two weeks. Because Antarctica is the windiest place on earth, sometimes you can't fly at all.

    We had a nervous wait over breakfast to find out if we'd be leaving that day. People have to stay in Stanley for weeks while the pilots wait for good weather.

    It turned clear at 9:30 and we took off at 10:30 on a little red plane called a Dash-7. But even when we were in the air, there was still a chance we wouldn't be able to fly the whole day.

Day 4: Wednesday   December 3

    After waking up in the Antarctic for the first time today I can understand why everybody who comes here falls in love with the place. It is really beautiful.

    We're staying at Rothera Survey base with mountains of ice all around. It is about minus 2⁰C today, which for me is very cold, but the regulars(常客) here are often seen walking around in T-shirts !

Day 5: Thursday   December 4

    I woke up to another beautiful sunny day here in the Antarctic. I'm told it's a bit colder today, about minus 5⁰C, but it's not very windy so it feels warmer. Those of us who are new to the base have to do a special training course before we're allowed to go off base to other stations or to go snowboarding over the nearby hill.

Day 7:  Saturday   December 6

    Not a cloud in the sky and it's warm enough to sit outside (in a jacket).

    The most amazing thing about this place is how the scenery (风景) changes every day.

    At first I thought I was going mad. I'd step outside in the morning and think, "I'm sure that big mountain of ice wasn't there yesterday." It's because the sea ice is always moving—slowly thankfully !
