A small, hand - propelled German submarine , the Brand-taucher, sank in 1851 in sixty feet of water , with her captain ,Wilhelm Bauer, and two crew members aboard. Her hull immediately began to collapse under the pressure of the sea. CaptainBauer , who had built the tiny craft, knew that if he could keep his two companions from panicking while allowing the water to rise steadily inside her , the interior and exterior pressure would equalize and they would be able to open the hatch and got out. They did.
While there are many differences between high school and college , I'd have to say that the most important ones all involve freedom. Everyone has to attend high school , at least until tenth grade , so very often you find classes where the students aren't serious about learning. College is exactly the opposite. People are there voluntarily because they want to learn and improve themselves. As a result college students are much more serious and interested. Another major difference is that colleges don' t enforce arbitrary rules. In high school you need a pass to be in the hallway during class, and you can' t leave a classroom without permission. On the other hand , college students can go where they please.
My grandfather's farm has become much easier to manage in recent years. His prize Holstein cows , for example , are now milked by automatic pumps rather than by hand. Also , the eggs his hens lay are hatched in incubators instead of by the hens themselves. The temperature and humidity in the hen houses are controlled by thermostats, not by Nature' s whim; and the amount of food his chickens get each day is determined by a computer rather than by a farmhand's estimates. All that is left for grandfather to go , he jokes, is to sit back and pay the huge electric bills.
In ferreting the interests of people in space, we are aware that there are probably three reasons. Firstly , it is a plan of looking for other places to hold the overcrowded population on this
earth. Secondly , it is the curiosity of mankind to urge the scientists for the research work, because they desire too eagerly the coming of the day when they can travel freely in space. Thirdly, we are reminded of the mineral sources which are not sufficient to provide for the needs on the earth, so we try every effort to go to other planets in the hope for searching for new resources.
My ambition is to go to college, but my environment does not allow me to do so. My father has been in some difficulty in supporting me even in the middle school, so it is certainly a greater difficulty for him to pay my expenses in college. And I have five brothers in schools. If I go to college, the burden will be too heavy for my father. Moreover, I am poor in science, and perhaps this will prevent me from being successfully assigned the entrance of a college.
