关注本站了解更多关于文四级和大英竞赛相比哪个难，公共英语三级跟大学四级哪个容易考和英语四级成绩查询的相关信息。
公共英语三级跟大学四级哪个容易？
公共英语三级比大学四级容易。1. 因为公共英语三级考试内容对比大学四级更简单，语法和词汇量都要求较少。2. 公共英语三级的考试时间也比大学四级短，唯有2小时，而大学四级的考试时间是2.5小时。3. 除开这点公共英语三级考试时间分配更为合理，获取高分的门槛比大学四级低。因为这个原因，综合来看，公共英语三级相对来说更容易通过。
1. 考试内容差异：公共英语三级考试试卷主要测试英语的基础知识和实质上运用能力，涵盖听力、阅读、写作和翻译等方面。而大学英语四级考试试卷则更加重视英语地运用能力和语言感知，涉及的语言难度和应用场景更为复杂。
2. 考试对象的不一样：公共英语三级考试试卷主要面向高中和中职学生、大学生还有其他英语学习者，而大学英语四级考试试卷则主要面向本科生，学员的英语基础和学习经历可能会带来一定不一样。
四级考试和大英竞赛是完全不一样的考试类型，难度大小很难直接进行比较。
四级考试是中国大学英语四级考试，也称CET-4是中国教育部主管的全国性英语考试和评级标准之一，考核学员英语听、说、读、写的能力。大多数情况下要求学员具备一定的英语听说读写能力，考试难度适中，难度可能会随着每一年的考试试卷难度而出现变化。

The materials and tools used for paper cutting are simple: paper and a knife. Paper-cut works are usually made of red paper, because red is associated with happiness in traditional Chinese culture. Therefore, in weddings, Chinese New Year and other festive occasions, red-colored paper-cutting is the first choice to decorate doors and windows.2019年12月卷一ι.New York City police captured a cow on the loose in Prospect Park on Tuesday after the animal became an attraction for tourists while walking along the streets and enjoying the park facilities. The confused creature and camera-holding humans stared at each other through a fence for several minutes. At other times the cow wandered around the526-acre park and the artificial grass field normally used for human sporting events. Officers used soccer goals to fence the animal in. However, the cow then moved through one of the nets, knocking down a police officer in the process. Police eventually trapped the cow between two vehicles parked on either side of a baseball field's bench area. An officer then shot an arrow to put it to sleep. Then officers waited for the drug to take effect. After it fell asleep, they loaded the cow into a horse trailer. It was not clear where the cow came from or how it got lost.

Due to the reform and opening-up, more and more parents can send their children abroad to study or participate in international exchange programs to broaden their horizons. Through these efforts, they expect their children to grow healthily and contribute to the development and prosperity of the country.5.4四级全套模拟训练模拟训练11.My View on College Students' Job-huntingNowadays, many college students find it hard to get good jobs after graduation. For one thing, students cannot find satisfactory jobs. For another, they find companies more and more demanding. That's why they may feel a lot of pressure in finding a job.Many reasons lead to this situation. To begin with, the whole society has become more competitive. More and more college graduates are hunting for jobs while the number of jobs is limited. In addition, employers prefer to choose the best among candidates because they have more choices. Last but not least, some students do not want to dothe basic work in a company; they hope to start their career at a high position as a manager and earn more money.As far as I am concerned, the whole society should do something to change this situation. First, college students should change their attitudes towards jobs. Second, universities should organize lectures about how to choose a suitable job. Third, companies should provide the graduates with some intern opportunities. These efforts will undoubtedly enable students to find satisfactory jobs.2.Phasing out the FM radio signal.3.Let broadcasters invest more in programming.4.Technology brings jobs to the disabled.5.More than 300.6.An egg a day may help young children grow to a healthy height.7.It divided participants into two groups.8.To have diversified foods in their diets.9.He had an adventure in Tokyo.10.Catch up on his sleep.11.He went to see an active volcano.12.He enjoyed the cool ocean breezes.13.

The most common use of red packets isduring the Chinese New Year when elders give red packets to children or members of the younger generation. The red color of the packet symbolizes good luck and is supposed to ward off evil spirits. In the Ming and Qing dynasties, adults gave bronze coins threaded with red strings to children as a lunar New Year gift to protect them from evil. Toda½ money is placed inside red envelopes, which are given to represent luck and wealth. In any case, the amount of money given is always even number and amounts ending with 8 are very popular as the number 8 sounds like “发“ in Chinese, which signifies prosperity.模拟训练21.Should cell phones be banned from the college classroom? This has been a controversial question for a long time. I admit that the cell phone has become quite helpful in our study and life, but on the whole I think it is beneficial for students if they are not allowed to bring their phones to college classes.There will be too many problems if students bring their cell phones to class. First, many college students choose to sit in the back of the classroom, eyes fixed on their cell phones. This could mean more class management and less teaching time for teachers. Secondly, the ring of the cell phone can pose a major distraction for other students, as well as teachers.Here are some good measures we can take to help solve this problem. Some schools use "cell phone bags" to collect students' cell phones in class. Besides, Wheneverthe class hears a phone ringing, the teacher could punish its owner by deducting his or her grade points.2.IT would play a much bigger role in many jobs.3.Training IT skills in the classroom.4.

邢帅教育英语四级课程介绍资料
大学四级英语课程第一课：介绍大学四级考试内容以及改革要求介绍各种科目学习方法介绍情侣一、四级考什么？大学英语四六级改革内容及应试方法改革内容：自2013年12月考次起，全国大学英语四、六级考试委员会将对四、六级考试的试卷结构和测试题型作局部调整。
调整后，四级和六级的试卷结构和测试题型相同。
(=￣ω￣=)根据很多童鞋反映，难度是增加了，至于增加了多少，这个就看各位的水平啦。
(ノへ￣、)一、四级考什么？听力听力是一项可以大量拉分的项目，很多童鞋做完听力都有摔耳机掐老师的冲动，为什么呢？笔者当年做完听力自我感觉很差，结果查了分数，虽然是过了，但是听力和凤姐一样让人不忍直视。
如果当时听力能够多几分，我也就可以非常非常高分了。
那么，听力究竟要怎么过呢？首先，大量地听。
让你的耳朵充分地对英语产生一种惯性，不会再听到英语的时候感到突兀和不自然。
接着，重点掌握听力里面经常出现的词汇，比如女神约你今晚9点过去，你听成明晚9点，你就杯具了。
词汇与语法这个东东的重要性就不必老师再多说了，它是学习英语的根基。
学习词汇是一件力气活，所以，一旦你想背好单词，要做好吃苦的准备。
当然，当你掌握了大量词汇，你就不是在吃苦，而是在吃苦瓜了，养气补血，十分有益身心健康。
首先，要有计划有目的去背单词，不能今天背两个，明天背一个，后天看韩剧。
接着，要重复地去背诵，不能今天看完就扔了。
阅读阅读外国文章是一件很高端洋气上档次的事情，可是当你看外文文章像便秘一样痛苦难堪，随着考试时间的流逝你越来越hold不住，那种心情十分的不爽。
首先，积累必要的词汇。
没有词汇量的基础，哪里能看懂英文文章呢？接着，养成一套适合自己的方法习惯，怎么说呢？有些人喜欢看问题之后再看文章，有些人喜欢看完文章再看问题。
从我的经验里，其实两种方法无所谓谁好谁坏，大家要去尝试，然后看究竟哪套更适合自己，而不必纠结于哪个“正确”。
写作写作是比较容易得分的，因为已经有很多模板和套路摆在那里，加上自己的观点，一篇不错的文章就浑然天成了。

2023年最新版四级听力辅导
这类短文重要是对社会中存在的某些现象，和某些问题进行揭示、剖析和研究，涉及社会政治、经济、家庭、犯罪、环境、公共交通等方面的内容，并对这些问题做出一种主观的评论，多以议论文为主。
比如：2023年12月的四级考试的第一篇短文就讲述了当今社会的人们不再象过去那样注重文明礼貌的现象，2023年6月第二篇短文讲述了如何制止滥用毒品这一社会问题，而2023年1月的第一篇讲述了战争导致的环境污染问题。
由于这类短文的选材一般是比较热门的话题。
考生在平时生活中或多或少都通过各种媒体或途径有所接触，只是不同的人对这些现象与问题的见解不同，因此论述的角度和观点就千差万别。
做这类题时，考生切忌以自己的观点或平时听到的别人的观点答题，而应以这些观点为基础和比较对象，去理解作者的见解，以听到的录音内容为基础进行答题。
这类短文设立的问题以主旨大意题和导致某个社会现象或问题的因素类题为主。
由于这类文章通常有主题句，且主题句常为短文的首句或尾句。
所以考生牢记第一时间进入状态，集中注意听清文章的开篇及结尾部分。
对于因素类题，一般在短文中都能直接提及，所以在预读选项，预测问题的基础上带着问题去听，听到什么选什么能大大减少答题的难度。
请看2023年12月CET-4的第一篇短文：11. A) The art of saying thank you. B) The secret of staying pretty.C) The importance of good manners. D) The difference between elegance and good manners.12. A) They were nicer and gentler.B) They paid more attention to their appearance.C) They were willing to spend more money on clothes.D) They were more aware of changes in fashion.13. A) By decorating our homes. B) By wearing fashionable clothes.C) By being kind and generous. D) By putting on a little make-up.

江西省南昌市2015-2016学年度第一学期期末试卷（江西师大附中使用）高三理科数学分析一、整体解读试卷紧扣教材和考试说明，从考生熟悉的基础知识入手，多角度、多层次地考查了学生的数学理性思维能力及对数学本质的理解能力，立足基础，先易后难，难易适中，强调应用，不偏不怪，达到了“考基础、考能力、考素质”的目标。
试卷所涉及的知识内容都在考试大纲的范围内，几乎覆盖了高中所学知识的全部重要内容，体现了“重点知识重点考查”的原则。
1．回归教材，注重基础试卷遵循了考查基础知识为主体的原则，尤其是考试说明中的大部分知识点均有涉及，其中应用题与抗战胜利70周年为背景，把爱国主义教育渗透到试题当中，使学生感受到了数学的育才价值，所有这些题目的设计都回归教材和中学教学实际，操作性强。
2．适当设置题目难度与区分度选择题第12题和填空题第16题以及解答题的第21题，都是综合性问题，难度较大，学生不仅要有较强的分析问题和解决问题的能力，以及扎实深厚的数学基本功，而且还要掌握必须的数学思想与方法，否则在有限的时间内，很难完成。
3．布局合理，考查全面，着重数学方法和数学思想的考察在选择题，填空题，解答题和三选一问题中，试卷均对高中数学中的重点内容进行了反复考查。
包括函数，三角函数，数列、立体几何、概率统计、解析几何、导数等几大版块问题。
这些问题都是以知识为载体，立意于能力，让数学思想方法和数学思维方式贯穿于整个试题的解答过程之中。
二、亮点试题分析1．【试卷原题】11.已知,,A B C 是单位圆上互不相同的三点，且满足AB AC →→=，则AB AC →→⋅的最小值为（ ）A ．14-B ．12-C ．34-D ．1-【考查方向】本题主要考查了平面向量的线性运算及向量的数量积等知识，是向量与三角的典型综合题。
解法较多，属于较难题，得分率较低。
【易错点】1．不能正确用OA ，OB ，OC 表示其它向量。
2．找不出OB 与OA 的夹角和OB 与OC 的夹角的倍数关系。
【解题思路】1．把向量用OA ，OB ，OC 表示出来。
2．把求最值问题转化为三角函数的最值求解。
【解析】设单位圆的圆心为O ，由AB AC →→=得，22()()OB OA OC OA -=-，因为1OA OB OC ===，所以有，OB OA OC OA ⋅=⋅则()()AB AC OB OA OC OA ⋅=-⋅-2OB OC OB OA OA OC OA =⋅-⋅-⋅+ 21OB OC OB OA =⋅-⋅+设OB 与OA 的夹角为α，则OB 与OC 的夹角为2α所以，cos 22cos 1AB AC αα⋅=-+2112(cos )22α=--即，AB AC ⋅的最小值为12-，故选B 。
【举一反三】【相似较难试题】【2015高考天津，理14】在等腰梯形ABCD 中,已知//,2,1,60AB DC AB BC ABC ==∠= ,动点E 和F 分别在线段BC 和DC 上,且,1,,9BE BC DF DC λλ==则AE AF ⋅的最小值为 .【试题分析】本题主要考查向量的几何运算、向量的数量积与基本不等式.运用向量的几何运算求,AE AF ，体现了数形结合的基本思想，再运用向量数量积的定义计算AE AF ⋅，体现了数学定义的运用，再利用基本不等式求最小值，体现了数学知识的综合应用能力.是思维能力与计算能力的综合体现. 【答案】2918【解析】因为1,9DF DC λ=12DC AB =，119199918CF DF DC DC DC DC AB λλλλλ--=-=-==， AE AB BE AB BC λ=+=+，19191818AF AB BC CF AB BC AB AB BC λλλλ-+=++=++=+，()221919191181818AE AF AB BC AB BC AB BC AB BCλλλλλλλλλ+++⎛⎫⎛⎫⋅=+⋅+=+++⋅⋅ ⎪ ⎪⎝⎭⎝⎭19199421cos1201818λλλλ++=⨯++⨯⨯⨯︒2117172992181818λλ=++≥+= 当且仅当2192λλ=即23λ=时AE AF ⋅的最小值为2918. 2．【试卷原题】20. （本小题满分12分）已知抛物线C 的焦点()1,0F ，其准线与x 轴的交点为K ，过点K 的直线l 与C 交于,A B 两点，点A 关于x 轴的对称点为D ． （Ⅰ）证明：点F 在直线BD 上； （Ⅱ）设89FA FB →→⋅=，求BDK ∆内切圆M 的方程. 【考查方向】本题主要考查抛物线的标准方程和性质，直线与抛物线的位置关系，圆的标准方程，韦达定理，点到直线距离公式等知识，考查了解析几何设而不求和化归与转化的数学思想方法，是直线与圆锥曲线的综合问题，属于较难题。
【易错点】1．设直线l 的方程为(1)y m x =+，致使解法不严密。
2．不能正确运用韦达定理，设而不求，使得运算繁琐，最后得不到正确答案。
【解题思路】1．设出点的坐标，列出方程。

即在考查基础知识的同时，注重考查能力的原则，确立以能力立意命题的指导思想，将知识、能力和素质融为一体，全面检测考生的数学素养，既考查了考生对中学数学的基础知识、基本技能的掌握程度，又考查了对数学思想方法和数学本质的理解水平，符合考试大纲所提倡的“高考应有较高的信度、效度、必要的区分度和适当的难度”的原则． 2. 试题结构形式大体相同，即选择题12个，每题5分，填空题4 个，每题5分，解答题8个（必做题5个），其中第22，23，24题是三选一题。
题型分值完全一样。
选择题、填空题考查了复数、三角函数、简易逻辑、概率、解析几何、向量、框图、二项式定理、线性规划等知识点，大部分属于常规题型，是学生在平时训练中常见的类型．解答题中仍涵盖了数列，三角函数，立体何，解析几何，导数等重点内容。
3. 在考查范围上略有不同，如本试卷第3题，是一个积分题，尽管简单，但全国卷已经不考查了。
