We all go through times when we feel we are not good enough. We might feel that way at work or in school or even as a parent. Here are some things to remember when you feel like that.

【小题1】 When I started my Ph.

【小题3】 It doesn’t exist. What’s perfect to me is not perfect to you. So if you think that there is some objective measurement of perfection and that the rest of the world is judging you on that，then you are wrong. Most people are too worried about their own lack of perfection to judge you.

【小题4】 Our sense of self-worth is based on our thoughts. We have been programmed for many years with thoughts about ourselves. Messages come from our parents，our peers，teachers，the media and our own labels. But guess what？They are only thoughts. Just because you think these thoughts，it doesn’t make them true.【小题5】

   Living in a house makes it a home. So leaving a place we have lived in and going to another place we haven't can be a little stressful.【小题1】 If you have a friend who is moving house，help make that change a little easier；help him or her make his or her new house“homey”by holding a house-warming party.

【小题2】 Is your friend going to be upset if his or her new house isn’t perfect when the guests ring the doorbell？If so，you will certainly want to plan the party ahead of time.【小题3】 If your friend wants to keep it more casual（非正式的），invite guests by phone，telling them it is an informal party.

If this is a new community for the homeowner， help him or her get used to it.【小题4】 This may break the ice and bring your friend more comfort. It is a great opportunity for your friend to develop relationships with the community members.

Help after the gathering ends. Moving is hard work. Your friend may be tired, and the last thing he or she will want to do is wake up to an after-party mess.【小题5】 Your friend will thank you for it.

Four Ways to Make Your Shoes Feel Better

According to the American Podiatric Medical Association, the vast majority of people experience foot pain at some point in their lives. The reason for most foot pain is that shoes fit poorly or force the feet into unnatural shapes. 【小题1】 . Aside from carefully selecting the right shoes, there are some easy measures you can take to keep foot pain at bay.

1. Stretch Your Shoes

If your feet are rubbing against your shoes, this could indicate that you need more width, length or both. However, sometimes going to the next larger size is not an option, as the next size may be too large. 【小题2】 .

2. Using Shoe Inserts

Both podiatrists (足病医生) and those in the shoe repair industry often recommend inserts to increase shoe comfort. 【小题3】 . Determining the best insert for your shoes depends on what hurts.

3. 【小题4】

The way you lace (用带子系紧) your shoes can make a world of difference in their comfort. Lacing them too tightly or incorrectly can make your feet hurt. Cramped toes, rubbing on the top of the foot, and pressure on the big toe can likely be relieved if you place your shoes differently.

4. Wearing Socks

【小题5】 . They are usually made of cotton or nylon. Not only do they add an extra layer of cushion to your shoes but they also keep your feet from sweating. This prevents moisture (水汽) from forming in the shoes. Moisture in your shoes can cause blisters and calluses on your feet.

   Researchers are placing robotic dogs in the homes of lonely old people to determine whether they can improve the quality of life for humans. Alan Beck, an expert in the human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study concerning the influence of robotic dogs on old people’s depression, physical activity, and life satisfaction. “No one will argue that an older person is better off being more active, challenged, or stimulated (刺激), ”Edwards points out. “The problem is how we promote that, especially for those without friends or help. A robotic dog could be a solution.”

In the study, the robotic dogs, called AIBO, are placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, researchers will collect data for six weeks. These old people will keep a diary to note their feelings and activities before and after AIBO being placed. Then, the researchers will study the data to determine if it has inspired any changes in the life of its owner.

“I talk to it all the time, and it responds (回应) to my voice,” says a seventy-year-old lady. “When I’m watching TV, it’ll stay in my arms until it wants to go down. It has a mind of its own.”

The AIBOs respond to certain orders. The researchers say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.

“At the beginning, it was believed that no one would relate to the robotic dog because it is metal and not furry,” Beck says. “But it’s amazing how quickly we have given up that belief.”

“Hopefully, down the road, these robotic pets could become a more valuable health helper. They will record their masters’ blood pressure, oxygen levels, or heart rhythms. AIBOs may even one day have games that can help stimulate older people’s minds.”

   Penguins are the number-one attraction for many visitors to Antarctica. If you go on a ship that is allowed to make shore landings, you may see them. But to get a close look at penguins, you have to be smart.

First of all, keep in mind that Antarctica’s visitor rules require that you remain at least five meters away from the penguins in order not to disturb them. You could easily become responsible for the death of a little penguin or the destruction of an egg if your too-close presence should disturb a penguin parent.

If a penguin is trying to move away from you, you must stop what you’re doing and back off even if you’re farther than five meters away. However, the rules don’t prevent a curious penguin from approaching within five meters of you — as long as the bird makes the move, not you.

Little penguins, in particular, are quite curious. I’ve seen several lucky tourists who were astonished to find that little penguins came right up to them. If a penguin comes extremely close to you, remember that you are not allowed to touch or hold it.

Here are more tips for getting close to penguins.

Ignore the smell: where penguins live is filled with guano（海鸟粪）and the smell takes some getting used to.

Be quiet because loud noises make penguins nervous. Fast or sudden movements signal meat — eating animals to penguins, and they react accordingly, so slow down when you walk around them.

Since it may take half an hour or more before the penguins get used to you, you need to be patient. Put away your camera — too often people are so focused on getting the pictures that they forget to look with their own eyes, but most of your most memorable experiences in Antarctica will be marked in your mind, not on a roll of films.
