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!

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 35 to 42.

Life in the Universe

Exobiology is the study of life that originates from outside of Earth. As yet, of course, no such life forms have been found. Exobiologists, however, have done important work in the theoretical study of where life is most likely to evolve, and what those extrateưestrial life forms might be like.

What sorts of planets are most likely to develop life? Most scientists agree that a habitable planet must be terrestrial, or rock-based, with liquid surface water and biogeochemical cycles that somewhat resemble Earth’s. Water is an important solvent involved in many biological processes. Biogeochemical cycles are the continuous movement and transformation of materials in the environment. These cycles include the circulation of elements and nutrients upon which life and the Earth’s climate depend. Since (as far as we know) all life is carbon-based, a stable carbon cycle is especially important.

The habitable zone is the region around a star in which planets can develop life. Assuming the need for liquid surface water, it follows that most stars around the size of our sun will be able to sustain habitable zones for billions of years. Stars that are larger than the sun are much hotter and bum out more quickly; life there may not have enough time to evolve. Stars that are smaller than the sun have different problem. First of all, planets in their habitable zones will be so close to the star that they will be “tidally locked” – that is one side of the planet will always face the star in perpetual daylight with the other side in the perpetual night. Another possible obstacle to life on smaller stars is that they tend to vary in their luminosity, or brightness, due to flares and “star spots”. The variation can be large enough to have harmful effects on the ecosystem.

Of course, not all stars of the right size will give rise to life; they also must have terrestrial planets with the right kind of orbits. Most solar systems have more than one planet, which influence each other’s orbits with their own gravity. Therefore, in order to have a stable system with no planets flying out into space, the orbits must be a good distance from one another. Interestingly, the amount of space needed is roughly the width of a star’s habitable zone. This means that for life to evolve, the largest possible number of life-supporting planets in any star’s habitable zone is two.

Finally, not all planets meeting the above conditions will necessarily develop life. One major threat is large, frequent asteroid and comet impacts, which will wipe out life each time it tries to evolve. The case of Earth teaches that having large gas giants, such as Saturn and Jupiter,.in the outer part of the solar system can help keep a planet safe for life. Due to their strong gravitation, they tend to catch or deflect large objects before they can reach Earth.

In order for life to develop, a planet’s orbit must not be

A. stable

B. very close to another planet’s orbit

C. on the same planet as another planet’s orbit

D. less wide than the star’s habitable zone
