Studies show that children who eat breakfast do better in school. It doesn’t take much further thought to know that adults will feel better and do better at work as well. Whether you work at home, on the farm, at the office, at school, or on the road, it is not a good idea to have no breakfast.
If we have no breakfast, we are likely to become tired when our brains and bodies run low on fuel (食物). By mid-morning, a lot of us grab a cup of coffee or eat a sugary candy bar to wake up again. This might work for a few minutes, but by lunch time we are hungry. Eating a good breakfast sets the tone for the rest of the day.
Having no breakfast is a popular way to lose weight, but not a smart one. Many people believe that they will lose weight if they have no meals, but that just isn’t true; the body expects to be refueled a few times a day, starting with a healthy breakfast.Eating breakfast is good for losing weight. In fact, people who eat breakfast are more likely to keep a healthy weight.
A healthy breakfast should have some protein (蛋白质) and some fiber (纤维). Protein can come from low fat meats, eggs, or beans. Fiber can be found in whole grains, vegetables and fruits. A good example of a healthy breakfast might be something simple like a hard boiled egg, an orange, and a bowl of whole grain cereal with low fat milk. Stay away from sugary foods and white bread because they are digested (消化) quickly and will leave you hungry and tired in several hours. Protein and fiber will keep you feeling full until lunch time.

Terraforming (Earth-forming) other planets, also known as planetary engineering (行星工程), seems like a task still centuries away for mankind to accomplish. However, it is a vigorous topic that attracts both popular and scientific interest. Why should the possibility of terraforming other planets be studied when it may be centuries before we know enough to even decide if it’s a good idea?
Mankind is getting more and more hard facts about other planets. The atmosphere of Venus has been explored; robots have surveyed the surface of Mars; Mercury, Jupiter and Saturn have been studied by spacecraft. Speculations have been answered; new questions have been raised, and enough hard data is right now becoming available to allow us to make the first attempt of planetary engineering.
In the past, people with excellent ideas about terraforming have kept them to themselves, or buried them in a desk drawer because they did not realize that anyone else was interested. But now, a wide circle of people has begun to do this kind of work. For instance, NASA funded a project on transforming Mars.
There are several strong reasons which demand that the possibilities of terraforming be studied carefully. First, it’s an exciting idea of a possible future for human beings. Such thinking has a valuable role in providing options for our future directions. Secondly, the techniques of terraforming will also help contemporary technologies in weather and climate control. Thirdly, such study may assist us in detecting any possible existence of extraterrestrial intelligence (SETI, The Search for Extraterrestrial Intelligence, 地外文明搜索) and alien (异己的) civilizations on other planets.
Though the mission is far beyond our reach at the moment, we should at least keep our options open. Through debate and study on this subject, the possibility of rebuilding other planets to make them suitable homes for people may come true some day in the future.
