Nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion. Both reactions release vast quantities of energy from relatively small amounts of matter; a modern thermonuclear weapon weighing little more than a thousand kilograms can produce an explosion comparable to the detonation of more than a billion kilograms of conventional high explosive.Even small nuclear devices can devastate a city. Nuclear weapons are considered weapons of mass destruction, and their use and control has been a major aspect of international policy since their debut.

珍惜时间的英语作文-Time Is Money

珍惜时间的英语作文:Time Is Money 导语：时间就是金钱，我们不可以浪费时间，下面是yuwenmi小编为大家整理的优秀英语作文，欢迎阅读与借鉴，谢谢! Time Is Money “Time is money.” This saying means that time is very valuable. But time is more valuable than money. The money we have lost can be gained again, but the time we have wasted cannot be regained. Moreover, sometimes persons can exist without money, but nothing can be done without time, just as no one can live without air. Despite being so valuable, time is often neglected by men. Since time is an invisible thing, men often waste their time unconsciously(无意地). Without anything to do, they may gossip from morning till night. Man can live only at most to about 100 years. It seems fairly long, but in fact it is rather short. We often say “How quickly time flies!” How many things can a man accomplish in such a short period? Hence we should use the valuable time properly to do

关于时间管理的英语作文 manage time

How to manage time Time treats everyone fairly that we all have 24 hours per day. Some of us are capable to make good use of time while some find it hard to do so. Knowing how to manage them is essential in our life. Take myself as an example. When I was still a senior high student, I was fully occupied with my studies. Therefore, I hardly had spare time to have fun or develop my hobbies. But things were changed after I entered university. I got more free time than ever before. But ironically, I found it difficult to adjust this kind of brand-new school life and there was no such thing called time management on my mind. It was not until the second year that I realized I had wasted my whole year doing nothing. I could have taken up a Spanish course. I could have read ten books about the stories of successful people. I could have applied for a part-time job to earn some working experiences. B ut I didn’t spend my time on any of them. I felt guilty whenever I looked back to the moments that I just sat around doing nothing. It’s said that better late than never. At least I had the consciousness that I should stop wasting my time. Making up my mind is the first step for me to learn to manage my time. Next, I wrote a timetable, setting some targets that I had to finish each day. For instance, on Monday, I must read two pieces of news and review all the lessons that I have learnt on that day. By the way, the daily plan that I made was flexible. If there’s something unexpected that I had to finish first, I would reduce the time for resting or delay my target to the next day. Also, I would try to achieve those targets ahead of time that I planed so that I could reserve some more time to relax or do something out of my plan. At the beginning, it’s kind of difficult to s tick to the plan. But as time went by, having a plan for time in advance became a part of my life. At the same time, I gradually became a well-organized person. Now I’ve grasped the time management skill and I’m able to use my time efficiently.

How to finance college education has become a matter of concern for many students. Different people have different ways to solve this problem. Some get all of the money from their parents. Some apply for a loan especially set up for college students. Some acquire the money completely by themselves, doing a full-time job in summer or winter holiday. Some other students may ask their parents for most of it and earn the rest in their spare time in college, by doing a part-time job. As far as I’m concerned, I prefer the last way.Having acquired most of the tuition and fees from my parents, I needn’t worry too much about the money and can concentrate on my study. On the other hand, a part-time job in my spare time makes my campus-life colorful. I can make a lot of friends, improve my abilities and learn lots of knowledge.

约定的时间 The Time of A Date(高中英语作文)

约定的时间The Time of A Date 高中英语作文 The time of a date has different standard for boys and girls. Girls always like to be late for about ten minutes while boys always reach the destination on time. If the girls are earlier than the boys, then the situation will become awkward, it is not polite to let a girl wait for a boy. But sometimes girls are always late for more than half an hour, which annoys the boys. It is said that if you call a girl to ask her if she is on the way, then she will answer you that she just goes out of the house, the truth is that she is still in the house. Most girls are late for making up for a long time. It is considerate to be late for a date for a few minutes, but it is impolite to be late for much time.约会的时间对男孩和女孩来说有不同的标准。女孩总是喜欢迟到大约十分钟,而男孩总是准时到达目的地。如果女孩比男孩早,那么情形就会变得尴尬,这是不礼貌的,让一个女孩等待一个男孩。但有时女孩总是迟到超过半小时,这让男孩子感到烦恼。据说如果你打电话问一个女孩她是否在路上,然后她会回答你,她已经出门了,事实上,她还在房子里。大多数女孩都因为化妆而迟到。约会迟到几分钟是可以体谅的,但迟到太多时间就是不礼貌的。

社会热点问题英语作文

汽车：The set of pictures present a distinguishable contrast of the role of the automobile over time: a century ago, people celebrated the invention of such rapid equipment for transportation, which could take us to wherever we want. Yet now, particularly in urban areas, the automobile is more of a trouble as its abundance results in frequent traffic jams. Drivers in the second picture even fall asleep when trapped in this “disaster”. Traffic jams have long been a problem that preoccupies many metropolitan cities such as New York, Tokyo, and Beijing. The harm and loss they cost are incalculable. First and foremost, they waste a huge amount of people’s time passed waiting idly in their cars. Secondly, cars in traffic jams produce more exhaust that exacerbates air pollution. Most importantly, a severe traffic jam might results in the dysfunction of a whole city, which can affect residents’ life as well as businesses and industries. In my opinion, it is an urgent task to reduce the frequency of traffic jams. The first step should be to change people’s lifestyles fundamentally so that the car is no longer part and parcel of their everyday life. Governments also need to apply attractive measures to draw citizens to adopt means of public transportation, for instance, to reduce prices and improve relevant facilities. In short, the cease of traffic jams will largely ameliorate life quality in cities. 译文：这一组图展示了汽车在我们的社会中曾经扮演过的两种截然不同的角色：几个世纪以前，人们在庆祝发明了一种如此快速的交通工具，有了它我们可以去任何我们想去的地方。但是现在，特别是在城市地区，汽车倒更是一种麻烦，因为数目巨大的汽车导致了频繁的堵车现象发生。第二副图中的司机在这场“灾难”中都睡着了。堵车在很多大城市中是一个困扰人们很久的问题，比如在纽约、东京和北京。它造成的损失是无法估量的。首先，堵车使人们无聊地在车中等待，浪费了大量宝贵时间。其次，堵车时汽车产生了更多的废气，进一步加剧了空气污染。最重要的是，严重的堵车事件会导致整个城市的功能瘫痪，影响居民的正常生活和工商业的正常进行。我认为，努力降低堵车发生的频率是我们的一项紧急任务。第一步措施就是要改变人们的生活方式，并从根本上减弱汽车在我们的生活中的重要作用。政府还要采取有效的措施来促进市民利用公共交通工具，如通过降低价格、改进相关设施等。总的来说，减少堵车可以大大改进城市中的生活质量。 1. 产品质量低下问题 inferior quality of products 问题产生的原因 In the first place，Quite a few businessmen put the economic interests in the first place while overlook the importance of quality and safety. (Additionally，In order to reduce costs，they tend to use inferior materials，simplify the production process and shorten the manufacturing time.)
