雅思OG听力Test1-Section1答案解析
雅思OG听力Test1-Section1答案解析雅思听力怎么备考和答题?今天给大家带来雅思OG听力答案解析的内容,希望同学们可以从解析里领悟到雅思听力的和方法.接下来请看雅思内容:雅思OG听力Test1-Section1答案解析雅思OG听力Test1-Section1答案解析雅思OG听力答案解析(Answer analysis)Question 1? 定位句:I’m not sure where to go.替换词:start文章上来会先重复sample 的那一段,可以全神贯注准备定位第一题。
当录音说到I’m not sure where to go 的时候,就要注意力集中了。
注意关键词start,以及之前分析题目时确定的答案一定是个地方,马上就能定位到答案café.Question 2? 定位句: What time is the run? 替换词: begin说完前一句话之后,马上听到关键的提醒句what time is the run? 就知道接下来的关键信息要到了。
后面一句话提到两个时间,根据actual 选择第一个时间9am 为正确答案,8.45 只是一般的人arriving 的时间。
Question 3? 定位句: How long is the run?替换词: lengthen雅思听力备考细节介绍细节一:练习听力的时间这里提到的时间分为两个概念:练习听力的时间点和练习听力的时间长度。
就时间点而言,专家建议考生尽量选择上午的时间来练习听力,理由是听力考试是雅思考试的第一场考试并且是从上午9点开始。
考生需要调整好做听力题的最佳状态——与考试的时间点同步。
如果练习的时间不容易安排,至少是上午的时间。
强烈不推荐晚上练习听力。
就时间长度而言,不建议太长但也不要太短,两个小时左右最佳。
有的考生为了在听力成绩上取得更高的分数会连续做听力超过两个小时,但从实际的成绩来看,这种狂听的效果并不理想,由于时间长,大脑也比较累,因此很容易破坏我们听题时的瞬间注意力。

STAX脚本执行文档
1 STAX概述STAF(Software Test Automation Framework)是开源、跨平台、支持多语言并且基于可重用的组件来构建的自动化测试框架。
它为自动化测试建立了基础,并且提供了一种可插拔的机制支持不同的语言平台。
STAF采用点对点的实现机制,被用来减轻自动化测试的工作负担,加快自动化测试的进程。
在STAF环境中,所有的机器都是对等的,没有客户端和服务区的区分。
STAX是构建在STAF之上的执行引擎,可以方便地管理测试用例执行过程,包括测试用例的分发、执行、结果分析。
STAX是基于以下三种技术构建的:STAF、XML、Python。
STAX的官方网站是:/getstax.php2 STAX脚本STAX是通过脚本管理和执行测试用例的,这种脚本称为STAX脚本,STAX脚本是利用STAX 语言编写成的文件。
STAX语言是一种基于XML格式的脚本语言,并且采用Python语言处理变量和表达式。
STAX脚本可以方便地调用STAF提供的服务。
采用STAX编写的脚本文件也称为JOB。
我们在StaxScript.doc文档中对STAX脚本的编写规范进行了详细地介绍。
3 STAX格式这篇文档的重点在于如何执行编写好的STAX脚本。
STAX是作为STAF的一种外部服务嵌入到STAF中的,因此我们可以像执行FS、PING、EVENT、FTP等服务请求一样执行STAX请求。
这一部分内容我们就来详细讲解STAX服务可以处理的请求。
3.1 格式概述STAX可以处理以下请求:STAX处理的这些请求中,EXECUTE的作用是执行一个STAX脚本,大部分请求是调试STAX 脚本用的。
3.2 EXECUTEEXECUTE用于执行一个STAX脚本,格式如下:EXECUTE <<FILE <XML File Name> [MACHINE <Machine Name>]> | DATA <XML Data>> [JOBNAME <Job Name>] [FUNCTION <Function ID>] [ARGS <Arguments>][SCRIPTFILE < File Name>... [SCRIPTFILEMACHINE <Machine Name>]][SCRIPT <Python Code>]...[CLEARLOGS [<Enabled | Disabled>]][HOLD | TEST [RETURNDETAILS] |WAIT [<Number> [s|m|h|d|w]] [RETURNRESULT [DETAILS]]][NOTIFY ONEND [BYNAME] [PRIORITY <Priority>] [KEY <key>]][LOGTCELAPSEDTIME <Enabled | Disabled>][LOGTCNUMSTARTS <Enabled | Disabled>][LOGTCSTARTSTOP <Enabled | Disabled>][pythonoutput <PYTHON OUTPUT>] [PYTHONLOGLEVEL <Log level>][BREAKPOINT <Function Name> | <LINE> [@@<File>[@@<Machine>]] ] ...[BREAKPOINTFIRSTFUNCTION] [BREAKPOINTSUBJOBFIRSTFUNCTION]FILE:指明STAX脚本的名称,这个选项可以接收STAF变量MACHINE:指明STAX脚本所在的机器,如果没有指明,默认为提交STAX EXECUTE请求的机器,这个选项也可以接收STAF变量DATA:指定一段STAX程序,而不是STAX脚本文件JOBNAME:STAX脚本也称为JOB,JOBNAME用于给运行中的JOB起一个名字,这个名字不一定是STAX脚本的名字,这个选项可以接收STAF变量FUNCTION:指定调用STAX脚本时默认执行的函数,这个选项可以接收STAF变量ARGS:FUNCTION指定函数的参数,这个选项不可以接收STAF变量,可以处理私有数据SCRIPTFILE:这个选项指定一个Python脚本,这个Python脚本相当于STAX脚本中<stax>标签中的<script>包含的语句,这个Python脚本先于STAX中的函数执行,这个选项可以接收STAF变量SCRIPTFILEMACHINE:Python脚本所在的机器,如果没有指定,则和MACHINE为同一台机器,这个选项可以接收STAF变量SCRIPT:定义一组Python语句,相当于STAX脚本中<stax>中<script>包含的语句,这些python 语句先于STAX中的函数执行,可以接收私有数据CLEARLOGS:清除以前STAX脚本执行时生成的log信息,防止干扰。
Java里的堆(heap)栈(stack)和方法区(method)
Java⾥的堆(heap)栈(stack)和⽅法区(method)基础数据类型直接在栈空间分配,⽅法的形式参数,直接在栈空间分配,当⽅法调⽤完成后从栈空间回收。
引⽤数据类型,需要⽤new来创建,既在栈空间分配⼀个地址空间,⼜在堆空间分配对象的类变量。
⽅法的引⽤参数,在栈空间分配⼀个地址空间,并指向堆空间的对象区,当⽅法调⽤完成后从栈空间回收。
局部变量 new 出来时,在栈空间和堆空间中分配空间,当局部变量⽣命周期结束后,栈空间⽴刻被回收,堆空间区域等待GC回收。
⽅法调⽤时传⼊的 literal 参数,先在栈空间分配,在⽅法调⽤完成后从栈空间分配。
字符串常量在DATA 区域分配,this 在堆空间分配。
数组既在栈空间分配数组名称,⼜在堆空间分配数组实际的⼤⼩!哦对了,补充⼀下static在DATA区域分配。
从Java的这种分配机制来看,堆栈⼜可以这样理解:堆栈(Stack)是操作系统在建⽴某个进程时或者线程(在⽀持多线程的操作系统中是线程)为这个线程建⽴的存储区域,该区域具有先进后出的特性。
每⼀个Java应⽤都唯⼀对应⼀个JVM实例,每⼀个实例唯⼀对应⼀个堆。
应⽤程序在运⾏中所创建的所有类实例或数组都放在这个堆中,并由应⽤所有的线程共享.跟C/C++不同,Java中分配堆内存是⾃动初始化的。
Java中所有对象的存储空间都是在堆中分配的,但是这个对象的引⽤却是在堆栈中分配,也就是说在建⽴⼀个对象时从两个地⽅都分配内存,在堆中分配的内存实际建⽴这个对象,⽽在堆栈中分配的内存只是⼀个指向这个堆对象的指针(引⽤)⽽已。
<⼆>这两天看了⼀下深⼊浅出JVM这本书,推荐给⾼级的java程序员去看,对你了解JAVA的底层和运⾏机制有⽐较⼤的帮助。
废话不想讲了.⼊主题:先了解具体的概念:JAVA的JVM的内存可分为3个区:堆(heap)、栈(stack)和⽅法区(method)堆区:1.存储的全部是对象,每个对象都包含⼀个与之对应的class的信息。

定量资料的t检验
基本思路(1)
60≠18.56,为什么? 差别是由于抽样误差引起的,统计学上称为差异无统计学意义。 差异是本质上的差异,即二者来自不同总体。统计学上称为差异有统计学意义。
基本思路(2)
两者不等的原因: 同一总体,即 但有抽样误差存在; 非同一总体,即 存在本质上的差别,同时有抽样误差存在。
3.2 第Ⅱ类错误(type Ⅱ error) 如果实际情况与H0不一致,也仅仅由于抽样的原因,使得统计量的观察值落到接受域,不能拒绝原本错误的H0,导致了另一种推断错误。这样的错误称为第Ⅱ类错误。犯第Ⅱ类错误的概率为β。 接受了实际上不成立的H0,这类“取伪”的错误称为第Ⅱ类错误。其概率大小用β表示,β只取单尾。
=5.600
=13.233
解题步骤(2)
确定P 值,作出推断结论 查t 界值表, ,由于 ,故 ,在 =0.05的水准上拒绝 ,接受 ,差异有统计学意义,可以认为接受培训前后调查问卷得分有差别。

聚醋酸乙烯酯(PVAc)的合成与分析
聚醋酸乙烯酯(PV Ac)的合成與分析一、實驗目的:1.學習乳化聚合方法合成聚合體2.學習使用pH計3.學習使用萬能拉力試驗機4.學習分析紅外線光譜圖二、實驗原理乳化聚合第一次被使用是在第二次世界大戰時,製造1,3-Butadiene 及Styrene 之合成橡膠時的方法。
其較Bulk Polymerization 來說,熱傳及黏度的問題都能獲得良好的改善。
經乳化聚合所得的產物,稱之為乳液(Latex),有時產物不需再進一步處理就可直接拿來使用。
以水為分散媒(連續相),加入乳化劑(Emulsifier or Surfactant)及水溶性起始劑,在攪拌下進行聚合反應。
而一般典型之乳化聚合的進料如下:1.單體相:單體(油溶性,不溶於水)鏈轉移劑(油溶性,不溶於水,用於控制分子量大小)2.水溶液相:水(分散媒或連續相)起始劑(水溶性)乳化劑(具親水、親油端)市售的「萬能膠水」合成膠劑,即為乳化聚合的聚醋酸乙烯酯黏合劑,將醋酸乙烯酯單體分散於水中,利用過硫酸鉀為起始劑,加熱聚合生成高分子聚合物。
CH3CH2OC O33CH2OC OCH3nnVAc PVAc圖1 聚醋酸乙烯酯反應結構圖乳化聚合方法通常裝設簡單攪拌反應器,在加入乳化劑、起始劑的水溶液和單體後,一邊攪拌一邊加熱即可製備出乳液,一般聚合溫度控制在70~90℃之間。
因醋酸乙烯酯聚合熱較大,反應溫度上昇顯著,要想獲得高濃度之安定乳液較困難,因此一般採分批加入法。
乳化聚合法的優點為:1.容易控制:反應混合物的黏度遠小於相同濃度的真溶液,大量的水可增加其熱容量,且反應混合物可迴流。
2.可同時獲得高聚合速率和高平均鏈長(使用高乳化劑濃度和低起始劑濃度)。
3.乳液成品可直接利用。
4.乳液粒子小,有助於低程度殘留單體成品之獲得。
其缺點為:1.不易獲得純聚合體(乳化劑不易移除)。
2.欲收取固態聚合體需相當的技術。
3.水的加入降低了每單位反應器體積的聚合體產量。

SAT OG TEST1-答案
SECTION 1Sample Essay - Score of 6What motivates people to change is a relentless and innate desire for self-improvement. Rarely ever has history seen a man or society kick back, relax, and say “Well that about does it. Not much else to do here!” Within every person is the potential to achieve greatness in some form; be it athletically, mentally, spiritually. This inherent potential demands that people continue to explore and change both their environments and themselves throughout their life’s course. Ne ver should a man be idle for too long. After acknowledging the changes a man has already made to his environment, the pursuit of self-improvement will once again stir within his soul and call him to action. This internal desire, this pursuit of challenge and perfection, does not prohibit man from being happy with his status and achievements. On the contrary, the device serves more to allow the man to constantly strive for greater change, newer innovation. What motivates people to change is the ongoing need to redefine people’s lives and identities –to elevate them to higher levels of eminence and sucess.A good example of this can be seen in clinical psychology. When patients seek therapy for difficulties that have encumbered their daily functioning, they most often arrive for treatment voluntarily and willingly- they consciously accept the necessity of therapy and so participate without any duress. During the course of clinical therapy, the patient’s concerns, anxieties, ideas, emotions, and fears are brough t to light. However, the clinician does not try to alter the beliefs, feeling, and sentiments of his client; rather, he simply illuminates them in order to provide the patient with an accurate view of himself. The process, of raising concerns and ideas to the surface of conscious awareness, is known as clarification. Modern psychology is a far throw from the psychoanalysis of Freud’s time, in which psychologists attempted to “interpret” pre-and unconscious feelings that had been repressed by the patient. Because clinicians only clarify, and not dissect, alter, or interpret a client’s inner desires and emotions, the client himself is responsible for instituting change. If he is to change, he must dictate the course of therapy, and make the conscious choice to improve himself. This widely used approach is called “client centered therapy.” If the client’s ennui or ill feelings are due to situational factors or internal designs (as oppose to biological changes that would qualify for a diagnosis of psychopathology (mental disorder)), he must change them on his own accord to precipitate change within himself. The therapist will not “cure” him in any way. He alone must answer the call within himself to refine and redefine his identity and place in society. This need, of self-improvement, also initially brought him to the therapist. He was able to recognize the disorder of his environment and acknowledge his own negative feelings. This in turn brought him to therapy, where he was guided through a process of introspection that ultimately enabled him to improve himself, assuage his anxieties, and rightfully continue on his lifelong pursuit of even greater achievements.SECTION 21.ANSWERS AND EXPLANATIONSExplanation for Correct Answer D :Choice (D) is correct. “Setting” means the place in which a drama occurs. If one were to insert this term into the text, the sentence would read, “The setting of Maria Irene Fornes’ play Mud—a realistic room perched on a dirt pile—challenges conventional interpretations of stage sce nery.” Stage scenery is the key component of a play’s “setting,” and this scenery or “setting” is clearly unconventional.Explanation for Incorrect Answer A :Choice (A) is incorrect. “Appeal” means attraction or interest. If one were to insert this term into the text, the sentence would read, “The appeal of Maria Irene Fornes’ play Mud—a realistic room perched on a dirtChoice (B) is incorrect. The “plot” is the plan of action of a play. If one were to insert this term into the text, the sentence would read, “The plot of Maria Irene Fornes’ play Mud—a realistic room perched on a dirt pile—challenges conventional interpretations of stage scenery.” The phrase “a realistic room perched on a dirt pile” describes a “setting,” not a “plot.”Explanation for Incorrect Answer C :Choic e (C) is incorrect. “Mood” means a state of mind or feeling. If one were to insert this term into the text, the sentence would read, “The mood of Maria Irene Fornes’ play Mud—a realistic room perched on a dirt pile—challenges conventional interpretations o f stage scenery.” Nothing in the sentence indicates the play’s “mood.”Explanation for Incorrect Answer E :Choice (E) is incorrect. A “rehearsal” is a practice run of a show in preparation for a public performance. If one were to insert this term into t he text, the sentence would read, “The rehearsal of Maria Irene Fornes’ play Mud—a realistic room perched on a dirt pile—challenges conventional interpretations of stage scenery.” It is the “setting” of the play, not a practice run-through of the play, that challenges conventional interpretations of stage scenery.22.ANSWERS AND EXPLANATIONSExplanation for Correct Answer B :Choice (B) is correct. "Overabundance" means an amount that is more than what is needed, and "thrive" means to grow or prosper. If one were to insert these terms into the text, the sentence would read "Ironically, an affluent society that purchases much more food than it actually needs suffers because of that overabundance, since in conditions of affluence diseases related to overeating and poor nutrition seem to thrive." In this sentence "that overabundance" refers back to the phrase "more food than it actually needs." It makes sense that diseases related to overeating would "thrive," or prosper, in these conditions. The relationship between the two clauses is further signaled by the word "ironically," which means the opposite of what would be expected. It is ironic that an overabundance of food, a condition that would appear to result in good nutrition, actually leads to an increase in diseases related to poor nutrition.Explanation for Incorrect Answer A :Choice (A) is incorrect. "Lavishness" means excessive spending, and "adapt" means to change to fit new circumstances. If one were to insert these terms into the text, the sentence would read "Ironically, an affluent society that purchases much more food than it actually needs suffers because of that lavishness, since in conditions of affluence diseases related to overeating and poor nutrition seem to adapt." Although the first term fits in well with the overall sense of the sentence, the second term does not. Diseases are known to "adapt" or change to fit many different circumstances; it would not be ironic or unexpected for a change to occur in this situation.Explanation for Incorrect Answer C :Choice (C) is incorrect. "Corpulence" means obesity or excessive weight, and "vex" means to annoy. If one were to insert these terms into the text, the sentence would read "Ironically, an affluent society that purchases much more food than it actually needs suffers because of that corpulence, since in conditions of affluence diseases related to overeating and poor nutrition seem to vex." "Corpulence" is a term that refers more properly to people than to social conditions, and diseases are generally more likely to cause major discomfort than minor annoyance.Explanation for Incorrect Answer D :society that purchases much more food than it actually needs suffers because of that practicality, since in conditions of affluence diseases related to overeating and poor nutrition seem to awaken." Although the second term could fit in well with the overall meaning of the sentence, the first term is inappropriate. Buying more food than is necessary is not "practical" at all; it is wasteful.Explanation for Incorrect Answer E :Choice (E) is incorrect. "Commonness" means typical behavior, and "abound" means to be present in large numbers. If one were to insert these terms into the text, the sentence would read "Ironically, an affluent society that purchases much more food than it actually needs suffers because of that commonness, since in conditions of affluence diseases related to overeating and poor nutrition seem to abound." Although the second term could fit in well with the overall meaning of the sentence, the first term does not. A society that buys more than is necessary is not a typical society; relatively few societies suffer from "overabundance."33.ANSWERS AND EXPLANATIONSExplanation for Correct Answer E :Choice (E) is correct. "Therapeutic" means having healing or curing powers. If one were to insert this term into the text, the sentence would read "Because of the therapeutic effects of the hot springs, tourists suffering from various ailments flocked to the village’s thermal pools." People suffering from an illne ss naturally try to find ways to get better, so hot springs that are known to cure diseases or ease pain would surely attract people with various ailments.Explanation for Incorrect Answer A :Choice (A) is incorrect. "Succulent" means juicy. If one were to insert this term into the text, the sentence would read "Because of the succulent effects of the hot springs, tourists suffering from various ailments flocked to the village’s thermal pools." Springs or pools of water cannot be properly referred to as succulent. The term "succulent" usually refers to plants or foods that are juicy, not to pools, puddles, springs, or other bodies of water.Explanation for Incorrect Answer B :Choice (B) is incorrect. "Redolent" means sweet smelling. If one were to insert this term into the text, the sentence would read "Because of the redolent effects of the hot springs, tourists suffering from various ailments flocked to the village’s thermal pools." Hot springs are rarely described as sweet smelling. However, if such springs existed, they would not just attract tourists suffering from diseases. Healthy tourists would also be drawn to the hot springs because of their sweet smell.Explanation for Incorrect Answer C :Choice (C) is incorrect. "Cerebral" means brainy or intellectual. If one were to insert this term into the text, the sentence would read "Because of the cerebral effects of the hot springs, tourists suffering from various ailments flocked to the village’s thermal pools." Bodies of water cannot be properl y referred to as cerebral. "Cerebral" is a term used to describe people or activities.Explanation for Incorrect Answer D :Choice (D) is incorrect. "Mandatory" means required. If one were to insert this term into the text, the sentence would read "Because of the mandatory effects of the hot springs, tourists suffering from various ailments flocked to the village’s thermal pools." A doctor might tell a patient that bathing in certain hot springs is mandatory. However, the effects of the hot springs could not be properly referred to as mandatory.Explanation for Correct Answer C :Choice (C) is correct. "Provide" means to supply or make available, and an "investigation" is careful research or an inquiry. If one were to insert these terms into the text, the sentence would read "More valuable and comprehensive than any previously proposed theory of the phenomenon, Salazar’s research has provided the basis for all subsequent investigations in her field." This sentence makes the reasonable claim that Salazar's important research has "provided the basis for," or supplied the foundation for, additional research in the same field.Explanation for Incorrect Answer A :Choice (A) is incorrect. "Undermine" means to weaken, and an "advancement" is an improvement. If one were to insert these terms into the text, the sentence would read "More valuable and comprehensive than any previously proposed theory of the phenomenon, Salazar’s research has undermined the basis for all subsequent advancements in her field." Although the second term could fit well into the sentence, the first term cannot. If Salazar's research was truly valuable and comprehensive, it should have helped to advance, not weaken, future work in the field.Explanation for Incorrect Answer B :Choice (B) is incorrect. "Prepare" means to make ready, and a "debacle" is a sudden disaster. If one were to insert these terms into the text, the sentence would read "More valuable and comprehensive than any previously proposed theo ry of the phenomenon, Salazar’s research has prepared the basis for all subsequent debacles in her field." Although the first term fits in well with the overall meaning of the sentence, the second term does not. Salazar's research is said to be valuable and comprehensive. Thus it will not logically lead to disasters in her field.Explanation for Incorrect Answer D :Choice (D) is incorrect. "Dissolve" in this context means to break apart, and an "experiment" is a test or trial done to discover something. If one were to insert these terms into the text, the sentence would read "More valuable and comprehensive than any previously proposed theory of the phenomenon, Salazar’s research has dissolved the basis for all subsequent experiments in her field." Although the second term might fit in well with the overall meaning of the sentence, the first term does not. Salazar's research might challenge previous work, but it cannot logically break apart the basis for future work in the field.Explanation for Incorrect Answer E :Choice (E) is incorrect. "Reinforce" means to strengthen, and a "misconception" is a misunderstanding. If one were to insert these terms into the text, the sentence would read "More valuable and comprehensive than any previously proposed theor y of the phenomenon, Salazar’s research has reinforced the basis for all subsequent misconceptions in her field." The first term could well fit with the overall meaning of the sentence, but the second term cannot. Salazar's research would not be considered valuable if it strengthened misunderstandings in her field.55.ANSWERS AND EXPLANATIONSExplanation for Correct Answer A :Choice (A) is correct. "Thwart" means to prevent or defeat. If one were to insert this term into the text, the sentence would read "Dangerously high winds thwarted attempts to begin the space shuttle mission on schedule, delaying the launch by nearly a week." The scheduled launch of the space shuttle was delayed because high winds prevented a safe lift-off.Choice (B) is incorrect. "Forfeit" means to give up or surrender something. If one were to insert this term into the text, the sentence would read "Dangerously high winds forfeited attempts to begin the space shuttle mission on schedule, delaying the launch by nearly a week." The astronauts launching the space shuttle might "forfeit" their attempts because of high winds, but the winds cannot be said to have "forfeited," or given up, the attempts to launch the shuttle.Explanation for Incorrect Answer C :Choice (C) is incorrect. "Implement" means to accomplish or carry out. If one were to insert this term into the text, the sentence would read "Dangerously high winds implemented attempts to begin the space shuttle mission on schedule, delaying the launch by nearly a week." The high winds did nothing to help accomplish an on-time launch of the space shuttle. In fact, they prevented the launch from occurring on schedule.Explanation for Incorrect Answer D :Choice (D) is incorrect. "Discharge" means to release. If one were to insert this term into the text, the sentence would read "Dangerously high winds discharged attempts to begin the space shuttle mission on schedule, delaying the launch by nearly a week." The attempts to launch the space shuttle on schedule were in no way released by the high winds; in fact, the winds prevented these attempts.Explanation for Incorrect Answer E :Choice (E) is incorrect. "Redouble" means to strengthen. If one were to insert this term into the text, the sentence would read "Dangerously high winds redoubled attempts to begin the space shuttle mission on schedule, delaying the launch by nearly a week." The high winds clearly did not strengthen the attempts to launch the space shuttle on schedule, as the launch was actually delayed.66.ANSWERS AND EXPLANATIONSExplanation for Correct Answer B :Choice (B) is correct. "Haranguing" means giving a long, critical speech, and "intemperate" means excessive. If one were to insert these terms into the text, the sentence would read "The guest speaker on Oprah Winfrey’s talk show offended the audience by first haranguing them and then refusing to moderate these intemperate remarks." A speech criticizing an audience would surely be offensive, and remarks of this type would be properly described as "intemperate" or excessive.Explanation for Incorrect Answer A :Choice (A) is incorrect. "Flattering" means praising excessively, and "commendable" means worthy of praise. If one were to insert these terms into the t ext, the sentence would read "The guest speaker on Oprah Winfrey’s talk show offended the audience by first flattering them and then refusing to moderate these commendable remarks." The first term might fit into the sentence because flattery may offend people by its insincerity. The second term does not make sense when inserted into the sentence, however. No audience member would be offended by a person's refusal to moderate "commendable" remarks, especially those directed at the audience. Explanation for Incorrect Answer C :Choice (C) is incorrect. "Praising" means pointing out the good features of someone, and "radical" means extreme. If one were to insert these terms into the text, the sentence would read "The guest speaker on Oprah Winfrey’s talk show offended the audience by first praising them and then refusing to moderate these radical remarks." An audience that receives "praise" is unlikely to take offense, and such comments in any case cannot be viewed as extreme.Choice (D) is incorrect. "Enraging" means causing intense anger, and "conciliatory" means peacemaking. If one were to insert these terms into the text, the sentence would read "The guest speaker on Oprah Winfrey’s talk show offended the audience by first enraging them and then refusing to moderate these conciliatory remarks." Remarks that cause intense anger cannot be properly referred to as "conciliatory," or peacemaking.Explanation for Incorrect Answer E :Choice (E) is incorrect. "Accommodating" means doing a favor for, and "indulgent" means excessively generous. If one were to insert these terms into the text, the sentence would read "The guest speaker on Oprah Winfrey’s talk show offended the audience by first accommodating them and then refu sing to moderate these indulgent remarks." "Accommodating" speech is unlikely to offend an audience, and such remarks cannot be properly referred to as "indulgent."77.ANSWERS AND EXPLANATIONSExplanation for Correct Answer A :Choice (A) is correct. "Halting" means hobbling or walking with difficulty. If one were to insert this term into the text, the sentence would read "By the end of the long, arduous hike, Chris was walking with a halting gait, limping slowly back to the campsite." A person who is limping or struggling to walk after a tiring hike would be properly described as walking with a "halting gait."Explanation for Incorrect Answer B :Choice (B) is incorrect. "Robust" means healthy or energetic. If one were to insert this term into the text, the sentence would read "By the end of the long, arduous hike, Chris was walking with a robust gait, limping slowly back to the campsite." A person who is limping after a difficult hike could not be said to be walking energetically.Explanation for Incorrect Answer C :Choice (C) is incorrect. "Constant" means continuous or without changes in speed. If one were to insert this term into the text, the sentence would read "By the end of the long, arduous hike, Chris was walking with a constant gait, limping slowly back to the campsite." A "limp" is a type of walk that is irregular or unsteady. Thus a person who is limping cannot be properly described as walking with a "constant gait."Explanation for Incorrect Answer D :Choice (D) is incorrect. "Prompt" means without delay. If one were to insert this term into the text, the sentence would read "By the end of the long, arduous hike, Chris was walking with a prompt gait, limping slowly back to the campsite." A limp is a type of walk that involves considerable delay.Explanation for Incorrect Answer E :Choice (E) is incorrect. "Facile" means easy or effortless. If one were to insert this term into the text, the sentence would read "By the end of the long, arduous hike, Chris was walking with a facile gait, limping slowly back to the campsite." Because limping involves pain or difficulty, a person who is limping cannot be properly described as walking effortlessly.88.ANSWERS AND EXPLANATIONSExplanation for Correct Answer D :for example, raising their voices and pretending to swoon." Raising one's voice or pretending to faint are examples of the exaggerated actions known as "histrionics."Explanation for Incorrect Answer A :Choice (A) is incorrect. "Imperious" means domineering or bossy. If one were to insert this term into the text, the sentence would read "Actors in melodramas often emphasized tense moments by being imperious, for example, raising their voices and pretending to swoon." Although imperious people might raise their voices when giving orders, they would be unlikely to pretend "to swoon," or faint.Explanation for Incorrect Answer B :Choice (B) is incorrect. "Inscrutable" means difficult to understand. If one were to insert this term into the text, the sentence would read "Actors in melodramas often emphasized tense moments by being inscrutable, for example, raising their voices and pretending to swoon." The exaggerated movements described in this sentence would make a character's emotions easier to understand, not more difficult.Explanation for Incorrect Answer C :Choice (C) is incorrect. "Convivial" means festive or fun-loving. If one were to insert this term into the text, the sentence would read "Actors in melodramas often emphasized tense moments by being convivial, for example, raising their voices and pretending to swoon." Although people in festive moods might raise their voices in joy or laughter, they do not have a tendency to pretend to swoon.Explanation for Incorrect Answer E :Choice (E) is incorrect. "Solicitous" means caring about other people's needs. If one were to insert this term into the text, the sentence would read "Actors in melodramas often emphasized tense moments by being solicitous, for example, raising their voices and pretending to swoon." Solicitous people do not typically raise their voices or pretend to swoon; they are much more likely simply to ask people what they would like or need.99.ANSWERS AND EXPLANATIONSExplanation for Correct Answer E :Choice (E) is correct. Being able to understand sign language, to solve puzzles, to use objects as tools, to use language, and to recognize oneself in a mirror are all things commonly associated with humans and, in fact, things that have sometimes been thought to be uniquely human. The author of Passage 1 strongly suggests that dolphins have those abilities, too.Explanation for Incorrect Answer A :Choice (A) is incorrect. The point that the author of Passage 1 is trying to make by mentioning various activities is that these activities show a high level of intelligence. But, in and of themselves, these activities are not strongly associated with unusual sensitivity to the environment.Explanation for Incorrect Answer B :Choice (B) is incorrect. The nature of the studies reported in lines 2-8 of Passage 1 makes it likely that the studies were performed on dolphins that were in captivity. But there is no indication that the animals involved in those studies failed to thrive.Explanation for Incorrect Answer C :Choice (D) is incorrect. The kinds of activities that are mentioned in lines 2-8 of Passage 1 could all be done quite seriously. They could also be done playfully or done in a mixture of these two modes. These activities, therefore, do not specifically suggest that an animal carrying them out would be uncommonly playful.1010.ANSWERS AND EXPLANATIONSExplanation for Correct Answer B :Choice (B) is correct. The last sentence of Passage 1 makes a comparison of levels of intelligence, but according to the author of Passage 2, such comparisons "may not be especially helpful" (lines 21-22). The author of Passage 2 does not think that intelligence is a single uniform ability that different species happen to have in different amounts. Passage 2 suggests that there are different kinds of intelligence, and that the kind of intelligence a creature has is appropriate to that creature's way of life.Explanation for Incorrect Answer A :Choice (A) is incorrect. Although the author of Passage 2 might agree that intelligence is difficult to measure, such a measurement is really beside the point. The author of Passage 2 does not think that intelligence is a single uniform ability that different species happen to have in different amounts. Passage 2 suggests that there are different kinds of intelligence, and that the kind of intelligence a creature has is appropriate to that creature's way of life.Explanation for Incorrect Answer C :Choice (C) is incorrect. The author of Passage 2 may think that some of the studies already conducted were wrongheaded and conceptually flawed, but there is no indication of any doubt about the objectivity of those studies.Explanation for Incorrect Answer D :Choice (D) is incorrect. As far as dolphin intelligence in relation to dolphin activities is concerned, the author of Passage 2 is only prepared to say that dolphin intelligence is appropriate "for the dolphin's way of life." The author does not speculate about the level of intelligence required for that way of life.Explanation for Incorrect Answer E :Choice (E) is incorrect. The last sentence of Passage 1 talks about dolphins' awareness of their own individuality. So it would not be sensible for the author of Passage 2 to respond to this sentence by arguing that little is known about dophins' social behavior.1111.ANSWERS AND EXPLANATIONSExplanation for Correct Answer D :Choice (D) is correct. Passage 1 suggests the dolphins have "a level of intelligence that may be very near our own" (lines 11-12). Passage 2 says that, when it comes to dolphin intelligence, "we don't know, and comparisons may not be especially helpful" (lines 21-22). All that the author of Passage 2 is really prepared to say is that dolphin intelligence is different.Explanation for Incorrect Answer A :。

范文:SAMPLE ANSWERThis is an answer written by a candidate who achieved a Band5.5 score. Here is the examiner’s comment:The candidate has identified all the key features (hospital, ring road, new public car park, staff car park and bus station in 2010) but the descriptions are not always accurate e.g. [two features that still remained. This two features are City Hospital and staff carpark] whereas the staff car park was formerly a car park for both staff and public, while the mention of the bus station is not developed. Organisation is clear, however, with some good use of cohesive devices [According to | Apart from | The further additional features], although there is an error in the use of reference pronouns [This/These two features]. The range of vocabulary is sufficient for the task [two different years | features | remained | additional], though [features] is over-used.A spelling error is noted in the second line [sourrounded] but this does not cause any difficulty for the reader; similarly, the use of [around-turn] can be easily understood as ‘roundabout’. There is a mix of simple and complex sentences, mainly used accurately.Two maps illustrate, the way to get to a city hospital of two different years (2007 and 2010).According to both maps, the main features which is city hospital is sourrounded by Ring Road. In these two maps, there have been two features that still remained. This two features are City Hospital and staff car park. Apart from these two features there are some features that shows on 2010 map but haven’t shown on 2007 map. The additional features that appear on the map of 2010 are public car parte which located on the east-side of the city hospital. The further additional features are two around-turn on the hospital Rd. which can lead to the bus station.Overall, there are two major features that never change on both 2007 and 2010 map. These features are city hospital andstaff car park. However, there are some additional features that appear on the map of 2010 but not on 2007.

model test 1参考答案
Model Test 1Part I Writingsample:My View on Part-time JobsIt is quite common that many college students now take part-time jobs in their spare time. However, there is still a controversy about whether it is good or not. Some people think that taking a part-time job certainly brings some benefits to students.In the first place, it is good and effective for college students to get to know the society and learn how to get along with different kinds of people. What's more, taking a part-time job provides students with a golden opportunity to get some work experience, which will make them more competitive in the job market in the future. Finally, students can make some money, which can help to lessen their families' financial burdens.Of course, there are also some problems arising from students' taking part-time jobs. First, some students may spend too much time on their part-time jobs, then neglect their studies. Second, some students may be cheated by others since they are not mature enough to make correct judgments.As for me, I hold the view that college students need to have more access to the outside world. However, they should balance their social practices and academic studies. After all, they should know what their main task is.范文点评本文题目为“我对兼职工作的看法”,从三个提纲来看,有些人认为大学生找兼职工作可以了解社会、积累经验等,有些人认为兼职工作影响学习,据此判断此题为正反观点论证题,要求考生在论证两方观点后要提出自己的看法。
