Even if your school provides healthy foods，it can be easy to give in to your desire（渴望）and pick a less healthy choice when you are feeling really hungry. How do you take control of it？【小题1】 Here are a few reasons for you to pack your lunch or snacks at least twice a week:

Do you ever wait in the lunch line only to find that when you get to the front，you don’t like what they are serving？So you reach for pizza again. 【小题2】 Bringing your own lunch also lets you control exactly what goes into the food you eat.

It does not hurt to enjoy an occasional（偶尔的）serving of pizza and hot dogs. 【小题3】 A packed lunch a couple of times a week means you can enjoy some favorites you might not find at every school—like your mom’s chicken soup or some crisp apples.

If you have a big game or activity after school，plan a lunch and snacks that combine lean proteins with carbohydrates（糖类）. 【小题4】

Pack healthy snacks so you don’t feel tempted to step off campus for a fast—food lunch，or hit the corner store for a chocolate and a soda！Put the money you save on such snacks aside.

In a word，whether you pack your lunch or eat in the cafeteria，what is important is that you make healthy choices. If you are concerned that your cafeteria does not offer enough healthy options，get involved in trying to make changes. 【小题5】

   Communicating with your child's teacher is one way to help him succeed at school. But just how often should you contact the teacher，and what questions should you ask？How can you help your child succeed in school？

Jerry Parks，a social studies teacher is. to share his thoughts. Parks keeps in touch with parents through emails，class websites，and phone calls. " Parents who take an active interest in their children's work and school well-being are one of the biggest contributors to my students' success，"Parks says. Children of involved parents typically have higher self-esteem（自尊）and have fewer behavior problems in school. And students' grades usually improve when their parents become involved.

Parks suggests the top 6 ways parents can help their children succeed in school: first，make sure your child is at school every day possible. Missed work is generally more of a loss than made-up work is a gain；second，set a time and a place for your child to do homework. If he does not have homework，have him use the time to read；third，keep in touch with teachers，but don't do it too much. Most teachers appreciate parents caring enough to keep in touch a few times a term but do not appreciate parents expecting to contact on a regular basis. Besides，it seems appropriate to ask the teacher whether she thinks your child is giving his best effort in class and whether she has noticed any significant changes in your child's behavior or grades. More importantly，teach your child to build a character—it will improve social and academic skills more than anything else. Some things are simply wrong，and the world your child will grow up in will punish crimes，so give your child a head start. Last but not least，make time every day to talk with your child about the day's activities. Let him know you care，and really listen to what he has to say.

   Here are four principles (行为准则) I live by. Whenever I follow these guidelines, I am at my very best, feeling productive and happy.

Devote time.

No matter how talented we may be, it’s wrong to think we can do it all. 【小题1】 The value of our achievements is greatly decided by what we spend our time on. We need to realize that every day we should devote the time to what matters and have the courage to let the unimportant things go.

Focus your attention.

Very often it seems that we just can’t focus our attention, even though we know what we should be doing, right? Resistance (阻力) makes us get disturbed by distractions.【小题2】 Developing a plan for overcoming resistance is important for maximum productivity.

【小题3】

We need to make a balance between work and play, between creation and pleasure.【小题4】 Even if we feel energetic to work long hours, the most effective long-term way is to hold ourselves back when we feel crazy and follow a proper pace instead.

Keep moving on.

More important than setting big goals is to just keep going. I know this goes against most of the “ set great goals for yourself” advice, but it’s what works for me.【小题5】 And it always made me more worried than it helped. Now, what does work for me is to think about how to improve my life and take small steps to make it happen.

   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.
