the twentieth century has brought with it many advances. with those advances, human lives have changed dramatically. in some ways life is worse, but mostly it is better. changes in food preparation methods, for example, have improved our lives greatly.
the convenience of preparing food today is amazing. even stoves have gotten too slow for us. microwave cooking is much easier. we can press a few buttons and a meal is completely cooked in just a short time. people used to spend hours preparing an oven-cooked meal, and now they can use that time for other, better things. plus, there are all kinds of portable, prepackaged foods we can buy. heat them in the office microwave, and lunch at work is quick and easy.
food preparation today allows for more variety. with refrigerators and freezers, we can preserve a lot of different foods in our homes. since technology makes cooking so much faster, people are willing to make several dishes for even a small meal. parents are more likely to let children be picky, now that they can easily heat them up some prepackaged macaroni and cheese on the side. needless to say, adults living in the same house may have very different eating habits as well. if they don’t want to cook a lot of different dishes, it’s common now to eat out at restaurants several times a week.
healthful eating is also easier than ever now. when people cook, they use new fat substitutes and cooking sprays to cut fat and calories. this reduces the risk of heart disease and high cholesterol. additionally, we can buy fruits and vegetable fresh, frozen or canned. they are easy to prepare, so many of us eat more of those nutritious items daily. a hundred years ago, you couldn’t imagine the process of taking some frozen fruit and ice from the freezer, adding some low-fat yogurt from a plastic cup and some juice from a can in the refrigerator, and whipping up a low-fat smoothie in the blender!
our lifestyle is fast, but people still like good food. what new food preparation technology has given us is more choices. today, we can prepare food that is more convenient, healthier, and of greater variety than ever before in history.

nuclear technology: benecial or disastrous?
one question that has caused a great deal of controversy over the years is nuclear technology. although it offers a number of advantages in world peace and green power, it is also a dangerous technology. nuclear weapons pose the greatest threat to life. even the use of nuclear technology for peaceful purposes also carries some serious risks. in this essay, however, i intend to show how the benets of such technology counterbalance its disadvantages.
the opponents of nuclear power generally base their arguments on the danger it presents to the world. there are two main dangers: the risk of nuclear warfare and the nuclear disasters. the danger of nuclear war is obvious and if one thinks about chernobyl, it is easy to understand why people are worried about nuclear power, as it can cause major suffering.
there are, however, good reasons for believing that nuclear technology is generally advantageous. the first of these is that there has not been a major world conflict since the invention of nuclear weapons. although nuclear weapons have enlarged the mechanism of war by threatening to kill more people more secretly and more horribly than those of the past, it is generally agreed that such weapons should be the last thing to be thought of as a means to win a war because there would be no winner in any nuclear conflict. if anything goes wrong, the scale of destruction on human lives and civilization is beyond imagination. the nightmare of hiroshima is a vivid memory, so nuclear weapons hidden in stock somewhere serve to maintain world peace by theory of counter-attack .
the other most significant benefit relates to the environment. perhaps the greatest danger facing our world today is a combination of global warming and the greenhouse effect. this danger is caused partly by burning fossil fuel, which leads to our polluted atmosphere. nuclear power, however, is a much greener alternative which does not have such negative effects.
already power plants have been in operation in a number of countries. these are successful examples to be followed. all in all, although it is true that nuclear weapons pose the greatest threat to life, the use of nuclear technology for peaceful purposes is really bene cial. in all appearances, the fear of war is overcome by the need for economic development.

there is no denying the fact that it has been a hotly debated topic whether students should attend military training in china in the past years. opinions on this issue differ sharply. some hold the positive view while others are strongly against it. personally, i believe it is essential for students to attend military training.
first, to attend military training is a response to the call for a stronger national defense. though we are in a relatively peaceful age, the danger of wars never really fades. some western powers have never given up their attempt to overturn chinese government and subject china to their manipulation. therefore, every chinese should bear in mind his or her duty to guard the nation against invaders. military training among students is the most direct means to instill such awareness and familiarize young people with life in the troop.
secondly, military training serves as an effective way to temper young people’s willpower, develop their team-spirit and cultivate their sense of discipline. as a generation brought up in a peaceful and relatively well-off environment, youngsters today suffer a grave lack of willpower. compared with previous generations, they are more prone to saying die in the face of difficulties or setbacks. therefore, they can gain much through the trying drills of military training. besides, the honor of a military group depends on the effort of each member, which calls for supreme team-spirit, which is another quality that many current young people lack as they are self-centered. plus, perhaps there can be no other settings like the barrack that demands so much sense of discipline. in these senses, military training provides a perfect chance for those high-fed, coddled and even spoiled youngsters to learn life lessons.
last but not least, military training supplies a chance to build up students’ bodies. although most youngsters are enjoying a higher standard of living nowadays than their previous generations, their physical conditions are far from desirable.
those against military training may be worried by the assumption that a sudden increase of intense physical exercise, especially during summer, may do harm to students’ health and they may cite as evidence the deaths of some students during military training in the past years. but i should point out that those deaths are absolutely exceptional cases and are perfect evidence that students need more such training.
to sum up, military training is not only a means to strengthen student’s physique and willpower, but also an effective way to enhance their sense of national defense and foster their patriotism. though it proves too much for a few students, we should not give up eating for fear of choking. the only thing we need to do is to take measures to ensure that the least harm is done to the trainees.
