I would love to be happier，as I'm sure most people would，so I think it will be interesting to find some ways to become a happier person.

1. Exercise more

Exercise has such a deep effect on our happiness and well-being that it's actually been proven to be an effective strategy（策略）for overcoming depression. 【小题1】 It can also improve your body image，even if you don't lose any weight.

2. Sleep more

We know that sleep helps our bodies to recover from the day and repair themselves，and that it helps us focus and be more productive. 【小题2】

3. Spend time with friends and family

【小题3】Several studies have found that time spent with friends and family makes a big difference to how happy we feel. Almost all the other things that we think make us happy are actually just ways of getting more families and friends.

4. Go outside

Spend time in the fresh air to improve your happiness. 【小题4】 One study found that spending 20 minutes outside in good weather not only improved our positive mood, but broadened thinking and improved working memory.

5. Help others

To make yourself feel happier, you should help others. Spending money on other people makes us happier than buying stuff for ourselves. 【小题5】 A study of volunteering showed that volunteers were affected and felt unhappy when their opportunities to help others were taken away.

   For many，running has never been their favorite activity. But running can certainly be a great way to get fit and stay healthy.

Getting started is difficult.【小题1】 Running can be boring at times，but the effect on your body and mind is well worth that struggle of just getting up and running.

【小题2】 Every major city and many smaller cities have running communities. They are quite organized and willing to help. They will help you see your running goals through.

Start with short distances. Though the running community would love to have a new long-distance runner tomorrow，the fact is that that will not happen overnight. Try running one mile every day for the next 3 weeks. After that，add it to two miles and so on.【小题3】

Take part in a race. By signing up for a race in the near future，you will focus on a goal and be motivated（激励）to keep practicing for that event. I suggest signing up for a 5-kilometer race that will take place within one month.【小题4】

【小题5】 Motivation is a major factor in running success. Bring a friend along to push you through the times and motivate you in his own way.

   Have you ever had the experience of talking to someone and you think they are lying? Well, you are not alone. We’ve all had that feeling. But did you know that there are several things you can look for to see if you are being lied to?

Sometimes you can tell if a person is lying by observing what they do with their body. When people are lying they tend not to move their arms, hands or legs very far from their body. They don’t want to take up very much space because they don t want to be noticed. Sometimes a person who is lying will not look you in the eyes. Other times people who lie try to look at you in a strong way because they want to convince you they are telling the trugh.

Liars also use deflection. For example, if you ask a liar the question “Did you steal Fatima’s bag?” they may answer with something like “Fatima is my friend. Why would I do that?” In this situation the person is telling the truth, but they are also not answering the question. They are trying to deflect your attention. Liars may also give too many details. They may try to over-explain things. They do this because they want to convince you of what they are saying.

Often when a person is lying, they do not want to continue talking about their lie. If you think someone is lying, quickly change the subject. If the person is lying, they will spear more comfortable because they are not talking about their lie any longer. A little later, change the subject back to what you were talking about before. If the person seems uncomfortable again, they may be lying.

It’s very hard for a liar to avoid filling silence created by you. He or she wants you to believe the lies being woven; silence gives no feedback on whether or not you’ve bought the story. If you’re a good listener, you’ll already be avoiding interruptions, which in itself is a great technique to let the story unfold.

Just because a person is showing these behaviors, it does not mean they are lying. They might be shy or nervous. But, if you think someone is lying, you might want to use some of these techniques. Hopefully, you won’t need to very often.

   So let’s say that you’re sitting at a restaurant and when your food arrives, you take one bite and decide that something is preventing you from taking a second bite. No matter what the reason is, this dish is going back to the kitchen, and now it’s up to you to find a way to send it back politely.

First of all, the single most important thing to do when you’re sending something back is to do it immediately. If you eat half the dish before sending it back, the server and kitchen will believe that you really don’t need to send it back.

If a dish is too salty that it cannot be eaten, you should first let the server know what the situation is, and they’ll take it back to the kitchen and bring you a new one. Remember that it is not the server’s fault, so don’t take it out on them. Also, don’t be afraid that they’ll get angry at you, or someone will spit (吐) in your food. It’s their job to make sure that you’re satisfied, and if the kitchen clearly makes a mistake the server will be frustrated with the kitchen, not with the diner who has been served an inedible meal. A new dish will be cooked, and nobody’s going to spit in it.

There is, however, one example when you are sending back a dish which will really annoy both the server and the kitchen. If you order a pasta dish that contains pancetta but then send it back to the kitchen because you’re a vegetarian (素食者) and don’t know what pancetta is, and then congratulations because you’re one of the most unbearable types of customers a restaurant can have. A perfectly good plate of food is just thrown out because you don’t ask what pancetta is before ordering.

So the bottom line: Use common sense if you think that you need to send your dish back. If the kitchen do something wrong, then they’re on the hook for a new plate of food. If you do something wrong, then hopefully you’ve learned a lesson.
