The division commander instructed our battalion to get around to the rear of the enemy and launch a surprise attack. To do so, however, we had to cross a marshland and many of us were afraid we might get bogged down in the mud. Our battalion commander decided to take a

gamble. We started under cover of darkness and pressed on in spite of great difficulties. By a stroke of luck, the temperature at night suddenly dropped to minus 20 degrees Celsius and the marsh froze over. Thanks to the cold weather, we arrived at our destination before dawn and began attacking the enemy from the rear. This turned the tide of the battle. The enemy, caught off guard, soon surrendered.

Automobiles have, since their invention, revolutionized transportation, changing forever the way people live, travel, and do business. On the other hand, they have brought hazards, especially highway fatalities. However, today

the application of computer technology and electronic sensors in designing and manufacturing cars makes it possible to eliminate most of traffic accidents. For example, electronic sensors mounted in your car can detect alcohol vapor in the air and refuse to start up the engine. They can also monitor road conditions by receiving radio signals sent out from orbiting satellites and greatly reduce your chances of getting stuck in traffic jams.

He told me that from his own experience the decision makers who interview prospective employees like people who are well prepared. Those who make no endeavor to learn as much about his prospective employer as possible don't have much of a chance of success.

For my own part, I find that appearances are all too often deceptive. For

instance, you might be wrong if you judged by appearances only people like Edward Hyde Burton. In appearance, he seemed a man all of a piece. He was a tiny little fellow with white hair and mild blue eyes, gentle and candid. Nevertheless, he turned out to be very cruel. He insulted and fooled Lenny who was down and out and made him commit himself to an insane venture. What was still more surprising was that he was completely indifferent to Lenny’s death. Without doubt, Burton was a man with a heart of stone.

新标准大学英语4课后答案

我认为,选修第二专业并不适合每一位本科生。我大学本科主修英语专业,大一时就开始辅修经济学了。无疑,我是班里最用功的学生。我竭尽全力想同时达到两个不同专业的要求,但还是有不及格的时候。因为经济学需要良好的数学基础,我不得不花大量时间钻研数学,因而忽略了英语学习。 If you ask me, taking a second major isn’t good for every undergraduate. In my freshman year as an English major, I took economics as my minor. By all odds, I was the most hardworking student in my class. But try as I might to meet the requirements of the two different subjects, I still couldn’t do well enough to pass all the exams. Given that the study of economics required a good command of mathematics, I had to spend so much time on math that I neglected my English major. 第二学期,《英国文学》及《宏观经济学》两门课不及格给我敲响了警钟,这可是我一生中第一次考试不及格,这大大打击了我的自信心。虽然我不是一个容易向命运低头的人,在暑假结束的时候,我还是决定放弃经济学,以免两个专业都难以完成。当我只需修一个专业的时候,一切似乎又回到了正轨。 Failing English Literature and Macroeconomics in the second semester sounded the alarm for me. Thiswas the first time I did not pass a course in my life, which had greatly sapped my confidence. Although I was not a man who would easily bow to fate, as the summer break came to a close, I decided to give up economics for fear that I would fail in both subjects. Now that I had only one subject to attend to, everything seemed to be on the right track again. 一个人的穿着似乎能影响他的行为方式。譬如,在校内要穿校服是中小学生所必须严格遵守的规矩之一。倘若在学生着装整齐划一和行为的统一规范之间不存在一种象征性关联的话,校服便不可能如此盛行。 What you wear seems to dictate the kind of person you are supposed to be. Take primary school and high school students for example. One of the hard and fast rules they have to observe is that they must wear uniforms at school. There is no doubt that school uniforms would not have achieved their currency without a symbolic correlation between the uniformity of clothes and the students’ conformity to some common code of conduct. 然而,多年的学校生活让学生在内心里对随处可见的校服产生了抵触情绪,校服毕竟压制了个性的表达。为了弥补这种损失,学生常常会在周末穿流行的休闲装。直到上了大学,他们才会享受真正的着装自由,而服装上的无序与大学培养创造力、鼓励自由表达思想及展露才华密切相关。可惜这样的好景不会太长,经过一段相对短暂的自由之后,他们在毕业工作之后将再次经历着装规范的压力。 However, after years of school life, there is always a backlash secretly n ursed in the students’ mind against the ubiquitous uniform which suppresses the expression of individuality. To compensate for this loss, students try to hunt for more casual and popular clothes and wear them on weekends. It is not until they start university, however, that they can really enjoy the freedom of dress, an anarchy associated with the cultivation of creativity and the encouragement of the free expression of ideas and talents. But this situation won’t obtain for long. After a relatively short time of liberty, they may experience again the revived pressure of dress code as soon as they become professionals. 谈及目前经济萧条所带来的影响,学生活动的减少就是一个很好的例证。为了活跃校园生活,大学愿意划拨一部分资金来资助学生社团活动,但由于今年学校的预算大幅减少,对社团的资助也相应缩减了不少。显然,学生社团要恢复以前的活力就必须想办法克服自身的经济困难。有人主张招募更多会员,因为会员费的增加可以帮助他们度过难关。 When it comes to the effects of the current economic downturn, the decrease of student activities is a good case in point. To enliven campus life, the university is always willing to carve out money for activities organized by student clubs and societies, but such sponsorships have been pared down this year because of huge budget cut. Apparently, student organizations need to weather their own financial crisis if they want to recover from their current state of inactiveness. Some suggest enrolling more club members, on the ground that the consequent increase of membership fees may help them get out of the difficulty. 当然,如果有更多的会员交年费,而且缩减一些日常开支,我们还是能省下一些钱来组织活动的。但是,问题的关键在于社团活动的费用与参加活动的人数是成正比的,因此这种方法恐怕不太可行。要推进社团活动,同时又不使经费超支,我们必须群策群力,拿出别的筹钱方法,而不是仅仅依赖学校拨款和会员费。 No doubt, if we have more members paying the annual fee, and if we cut back on our daily expenses, we can spare some money for organizing activities. But the bottom line is that the expenses of these activities are in proportion to the number of participants. I’m afraid this won’t be of much help. To boost student activities and to avoid going into the red, we still need to pool our ideas and come up with some other ways of raising money, in lieu of relying only on university grants and membership fees. 2. 新的国家博物馆建成之后,一些市民和建筑师对于在一群极其美丽精巧的古建筑中建造一座现代建筑感到愤怒。其高昂的维护费用和古怪的形状也引发了大量的批评。显然,许多人对在这个古城中涌现

First, get off the sofa Background information About the passage: This is an article by an Education Correspondent, Alexandra Blair, published in September 2008 in The Times, a long-established British quality newspaper. In Europe generally, and in Britain in particular, for a number of years there has been a r i s i ng nu mber of stude nts who go to uni vers ity and therefore more new graduates seeking employment. However, for many graduates finding a job became harder in 2008 - 2009 because the economic downturn - then a rcccssion - meant that many employers werereducing their workforce. After their final exams, some students rested in the summer before looking for jobs and then they found that it was difficult to find employment in their field or at the level they wanted. The

You can't accomplish your goal of mastering the language unless you work at it for years. Well, it sounds as if I'm exag-gerating the difficulties, but the fact is I'm only telling the truth. 2) The principal is somewhat disappointed with the performance of the children. From what she has gathered, some of the teaching staff have neglected their pupils. She has just announced that strict work regulations have been made and that they apply to both Chinese and overseas teachers. 3) The teacher-directed and the child-directed approaches to teaching art represent two ex-tremes of opinion. Too many teacher-directed activities cannot be expected to effectively assist children in learning because of the rigid structure. On the other hand, too many child-directed activities may see a curriculum that is totally unstructured and out of con-trol. There are valid reasons to believe a teacher-guided approach would be a superior way to guide children's development. This approach combines some form of structure with the child leading the direction. II. Confusable Words 1. 1) continual 3) continual
