2024大学期末复习学习计划范本(五篇)

2024大学期末复习学习计划范本光阴似箭,日月如梭,如今大学生活已经过半,我们不再是那懵懂初入大学校园的高中毕业生,如果再不奋斗的话,那四年无忧无虑的享受的大学生活会给我带来哪些美好的回忆呢?大三了,是时候认真规划我们的学习和生活了。
一、专业课这一学年我们学习的基本全是专业课,专业课的重要性和实用性是我们以后工作或继续深造最最重要的法宝。
1、建议课后做好复习,把老师留的思考题认真的做一遍,这个过程我们一定会把这节课的书本放上好几遍,对加深记忆会有很大的帮助。
2、建议每个月各科出一套测试卷,开卷闭卷自己决定,但是要求一定要做完,不为别的,就为我们能够加深学习印象,在翻课本和做题的过程中,会发现我们的课后复习是不是做的到位,哪里还有不完善的地方,作进一步的改善。
同时也希望大家认真而非敷衍的对待每份测试卷,大三了,我们需要有更大的自觉性和更多对自己负责的态度。
具体每份测试卷由我们405、406、321、322四个寝室负责选题出题,并为大家提供准确的答案。
然后由学习委员进行编排和打印。
3、建议多参加班级组织的去动物医院或其他与我们学习有关的活动,大一的我们去动物医院只是为了满足好奇心、进行简单的参观,而现在我们去是为了了解更多的病例,抄录更多的病历,相信这些东西不仅能够帮助我们更好地理解老师课堂上讲的知识,更可能为我们以后的工作积累丰富的经验。
二、英语大三我们没有了英语课,意味着我们要放弃陪伴我们近十年带给我们无数欢乐和痛苦的英语吗?我想好多人都会说NO,作为社会认可的英语四六级证书,作为考研必考的英语试卷,作为好多兽药说明书上的英文解释,作为8090后代言词的语言…我们都没有理由说放弃。
我的建议是大学期间我们每个人都要把英语四级证书拿下!建议大家重视单词的积累,平时多听全国英语四六级真题的听力,将听力词汇予以积累和掌握,阅读方面要争取提高自己的阅读速度,培养自己捕获文章重点和把握文章大意的能力,翻译方面多积累那些常考句型、积累那些常被用于翻译重要词汇和词组,写作方面要多背点有点难度的好文章。

People are 2. eager to know who lived there before its discovery, how they lived, and why they 3.died out. Different theories give different explanations, but none is completely convincing. The EasterIslanders had their own system of 4.writing, different from any other in the world. No other 5.Pacific Islanders knew how to write. The American 6.Indians did not know how to write either. Who 7. taught the Easter Islanders how to write, or did they develop their own system? Remember that writing was first invented in Asia only a few thousand years BC.8.. The Easter Islanders lived on sweet potatoes they farmed. These sweet potatoes came from the Americas How did the Easter Islanders get them? Is it possible that a few Easter Islanders traveled 2,300 miles to Chile, got sweet potatoes, and brought them back? But this is unlikely.9. Remember that the distances involved were great, further than the distance from Europe to the closest place in the Americas, which was only colonized in 1492. Could Easter Island have been colonized by people from Chile? Yet, DNA taken from graves dug up on Easter Island has shown that these people were Polynesians, not American Indians. The Polynesians lived on the sea and knew how to travel thousands of miles in their small canoes. They knew where they were going. The American Indians did not know how to do that. Yet, 10. a few American Indians could have reached Easter Island, because of a storm, and brought the seeds of sweet potatoes with them. Also, the seeds could have been brought in the stomachs of birds.Legend has it that the Great Chicago 1. Fire of 1871 began when Mrs. O'Leary's cow 2. kicked over a lantern, setting her straw on fire, which destroyed 3more than seventeen thousand buildings, left 4. a hundred thousand people homeless, and killed 5.. at least two hundred fifty Less well-known is the fact that the whole of the American Midwest 6. fell victim to disastrous fires on the night of October 8, 1871, People did not pay enough attention to Peshtigo, a small town. It fared 7. far worse in terms of 8. lives lost. Half the town--- 9. 1000 people ---died that terrible night. Not a 10.. single structure was left standingWhere did the 11. flames come from? A Peshtigo survivor wrote, "Countless fiery tongues 12. struck down into 13. the village, piercing every 14. object that stood in town. There was no obvious 15. beginning of the fire; the flame just 16.. swept across the town in an instant" What eyewitnesses described was more like 17a disaster from heaven than 18. a n accidental fire started by a nervous cowF1.

While most people work a five-day workweek, 1. when the hardware costs outweigh human costs, the 2. competitiveness of the modern economy means that leaving a factory idle for two days or an office 3.unmanned is too great an expense. Thus, many workers 4.regularly work on weekends. Since this is seen as a greater burden, most employers pay 5.extra or weekend work, either by agreement or by law.

The changes made 5. through biotechnology do not violate 6. the classification of a species. What you get when you insert 7. a gene is an 8.. organism that has a new trait Since we humans are a part of 9. the natural universe, everything we do is 10. natural. In biotechnology we use enzymes that we 11. isolate from nature to link together 12.pieces of DNA in the same manner that 13occurs in nature.. We even use a bacterium that is 14. a natural genetic engineer to introduce the new genes 15. into the plant. Moreover, 16.plant breeding is also natural. The public should 17.be more open-minded about new biotechnology, whose development will 18. benefit mankind a great deal.Studies of human stem cells may (S1) 1.yield information about the complex events that occur during human development. A primary goal of this work is to (S2) 2.identify how stem cells become divided or differentiated. Scientists know that turning genes on and off is (S3) 3. central to this process. Some of the most serious medical conditions, such as cancer and birth defects, are due to (S4) 4.abnorma l cell division and differentiation. A better understanding of the genetic and molecular controls of these processes may yield informationabout (S5) 5.how such diseases arise and suggest new strategies for therapy. A significant barrier (S6) 6. to this use and most uses of stem cells is that scientists do not yet fully understand the (S7) 7.signals that turn specific genes on and off to influence the differentiation of the stem cell.(S8) 8.The most important potential application of human stem cells is perhaps the generation of cells and tissues that could be used for cell-based therapies. Today, donated organs and tissues are often used to replace ailing or destroyed tissue, but the need for transplantable tissues and organs far outweighs the available supply. (S9) 9.Stem cells, directed to differentiate into specific cell types, will offer a source of replacement cells and tissues to treat diseases including Parkinson's and Alzheimer's diseases, spinal cord injury, stroke, burns, heart disease and diabetes. it may become possible to generate healthy heart muscle cells in the laboratory and then transplant those cells into patients with chronic heart diseaseF1.

The new law 5. increases government aid for farmers, which costs 6. 190,000 million dollars over the 7. next ten years. Critics say the measure forces down 8. world crop prices and reduces 9. the money earned by farmers in developing countriesAgriculture Secretary Ann V eneman said the proposal would end 10. all government assistance for farm exports over 11. five years. The United States also urged other countries to 12. cut taxes on food and agricultural imports.The proposal also would 13 limit.. government aid for farmers to 14 five percent of the value of a country's agricultural production, or from the present 15. 19,000 million dollars a year to 16. 10,000 million dollarsThe U.S. economy lost steam in the second quarter as consumers hit by high-energy costs turned thrifty.U.S. gross domestic product, a (S1) 1. measure of total output within the nation's borders, climbed at a (S2) 2.modest and weaker-than-expected 3 percent annual rate in theApril-June period, Commerce Department data (S3) 3.showed.Consumer spending rose at an insignificant 1 percent rate, a mere shadow of the 4.1 percent jump of the first quarter and the (S4) 4.weakest gain since the second quarter of 2001, when the economy was in recession.The degree to which consumers were (S5) 5. reluctant to buy surprised Wall Street analysts. A leading (S6) 6. economist, John Lonski, called the spending gain "shockingly small".(S7) 7. Analysts said big energy price hikes were one factor that hit consumer spending in the spring.(S8) 8..
