THE IMPORTANCE OF FIRST IMPRESSIONS

We have all heard the expression, “you can’t judge a book by its cover.” However, it seems that is exactly what most people do. The human brain seems to be wired in such a way that we make very strong, lasting

judgments about the people we meet within the first 30 seconds. And it is true, you may be able learn a lot about a person by their first impression. But can you really learn all you need to know?

May be there is something affecting your first impression. Possibly the person is nervous or upset. Maybe you are in a bad mood or not feeling well. All of these factors and more could influence a first impression, so should people place so much weight on it?

Many people feel that a first impression is extremely important. Once those people form an idea of you, it is often difficult for them to get beyond it. If someone feels that you are something you really aren’t because of your first impression, then that is obviously not a good thing.

Yet many people really do still rely deeply on first impressions. One good example is the job interview. We dress nicely for job interviews for a very good reason: to make a good first impression. In addition to our outward appearance, many people tend to put on something of an act. By being extremely polite and showing interest, we feel that we will make a good first impression and have a better chance getting the job.

Is this the way things should be? Probably not. Will this situation ever change? The answer to that question is the same - probably not. It is just human nature to rely on a first impression. Everyone knows that they do it and most people know that it's not the right thing to do.

The author thinks that people will continue to rely on first impressions because_____.

A. people refuse to change

B. people like to deceive other people

C. it’s human nature

D. it’s easy to change them

Househusbands

Dear Editor,

I read with interest the article on American families. In general I agree with it, but there are some important things it left out. It didn't tell the reader much about the life of a househusband. It's not an easy life. I know, because I'm now a househusband myself. A househusband has to change many of his ideas and his ways.

First of all, he has to change the way he thinks about time. Before I was a househusband, I worked full-time for the New York Times. I was a reporter, and time was always important. We had to finish our article quickly and give them to the editor. Everyone was always in a hurry. This is the way, many other men work, too. Businessmen, lawyers, bankers, and doctors all have to work quickly.

At home it's different. The househusband cannot be in a hurry all the time. If you rush around, you will make everyone unhappy! The children will be unhappy because they don't understand. For them, time is not important. Your wife will be unhappy because the children are unhappy. You will be unhappy, too, because they are all unhappy. So you have to learn to slow down. That is the first and most important rule for a househusband.

There is something else the househusband must learn. You must learn to show how you feel about things. At work, men usually do not talk about feelings. If they do, people think they are strange. So, many men are not used to telling anyone about their feelings. They do not know how to talk about their anger, worries, or love. But children need to know how you feel. They need to know how much you love them. If you are angry, they need to know why. Your wife also needs to know about your feelings. If you do not say anything, your family may get the wrong idea. Then there may be serious problems.

People talk a lot about househusbands these days. Usually they talk about men doing the housework, the cooking, cleaning, and shopping. But in my opinion, these are the easiest things to learn. It was much harder for me to change the way I think and the way I act with my family. I think, other men will also find this harder, but, like me, will find it necessary if they want to have a happy family!

These structures formed thousands, million, even billion years ago, from a dead body of ancient bacteria, plant, dinosaurs, fish, mammal,...etc, so why they maintain many textures of creatures.
