冬与夏不能两刑．,草与稼不能两成,新谷熟而陈谷亏,凡有角者无上齿,果实繁者木必庳,用智褊者无遂功,天之数也。

故天子不处全,不处极,不处盈。

全则必缺,极则必反,盈则必亏。

先王知物之不可两大,故择务,当而处之。

有便于学者,无不为也;有不便于学者,无肯为也。

盖闻孔丘、墨翟．．,昼日讽诵习业,夜亲见文王、周公旦．．．而问焉。

用志如此其精也,何事而不达?何为而不成?故曰:“精而熟之,鬼将告之。

《大学物理AII》作业 No.11热力学第一定律

《大学物理AII 》作业No.11热力学第一定律一、选择题1.置于容器内的气体，如果气体内各处压强相等，或气体内各处温度相同，则这两种情况下气体的状态[B](A)一定都是平衡态。

(B)不一定都是平衡态。

(C)前者一定是平衡态，后者一定不是平衡态。

.(D)后者一定是平衡态，前者一定不是平衡态。

解：气体内各处压强相等或温度相等，都不一定是平衡态。

2.一定量的理想气体，开始时处于压强、体积、温度分别为1p 、1V 、1T 的平衡态，后来变到压强、体积、温度分别为2p 、2V 、2T 的终态，若已知12V V >，且12T T =，则以下各种说法中正确的是：[D](A)不论经历的是什么过程，气体对外所做的净功一定为正值。

(B)不论经历的是什么过程，气体从外界所吸的净热量一定为正值。

(C)若气体从始态变到终态经历的是等温过程，则气体吸收的热量最少。

(D)如果不给定气体所经历的是什么过程，则气体在过程中对外所做的净功和从外界吸热的正负皆无法判断。

解：∫=21d V V V p A 只适用于准静态过程，对于任意过程，无法只根据12V V >，12T T =判断A 和Q 的正负。

3.一定量的理想气体，经历某过程后，它的温度升高了。

则根据热力学定律可以断定：(1)该理想气体系统在此过程中吸了热。

(2)在此过程中外界对该理想气体系统做了正功。

(3)该理想气体系统的内能增加了。

(4)在此过程中理想气体系统既从外界吸了热，又对外做了正功。

以上正确的断言是：[C ](A)(1)、(3)。

(B)(2)、(3)。

(C)(3)。

(D)(3)、(4)。

(E)(4)解：内能是温度的单值函数，温度升高只能说明内能增加了，而功和热量都与过程有关，不能只由温度升降而判断其正负。

4.热力学第一定律表明：[C ](A)系统对外做的功不可能大于系统从外界吸收的热量。

(B)系统内能的增量等于系统从外界吸收的热量。

(C)不可能存在这样的循环过程，在此循环过程中，外界对系统做的功不等于系统传给外界的热量。

The lead summarizes the principal items of a news event. The second paragraph and each succeeding paragraph contain secondary or supporting details in order of decreasing significance. All the paragraphs in the story contain newsworthy information, but each paragraph is less vital than the one before it. Inverted-pyramid form puts the climax of a story at the beginning, in the lead.5) leadA lead is a terse opening paragraph that provides the gist of thestory and invites readers inside.2. What is the difference between hard news and soft news? Hard news events, such as killings, and speeches by leading government officials, are timely and are reported almost automatically by the media. Soft news events, such as a car wash by a fourth-graders to raise money for a classmate with cancer, are not usually considered immediately important or timely to a wide audience. These events still contain elements of news, however, and the media often report them.3.

What are the major criteria for newsworthiness?ProximityProminenceTimelinessImpactConflict and ControversyUniquenessHuman interest5. What are the principles of news writing?News writing tends to be:1. Impersonal to make it appear objective (to distance thereporter from the story) hence:– Written in the third person– Use of direct speech or indirect speech which is attributed to someone other than the reporter,– Some use of passive verbs but usually only when someone who is being quoted wants to distancethemselves from an issue and to show objectively about n issue.2. About something that has taken place so mostly written in thepast tense.3. Simple – In fact close to the way we talk –relatively shortsentences and words and some use of clichés which the whole audience understand.4. Punchy –it must g rab the reader’s attention so often uses:– short rather than long words– active verbs– relatively short sentences– concrete rather than abstract vocabulary– sometimes emotive and colorful vocabulary– some use (but not overuse) of adjectives5. But also relatively formal hence:– no use of contractions– sentences written in full (no elision) or elliptical sentences6. sometimes imagery is used to help create a clearer mentalpicture for the reader.7. often including the reporter’s by-line and/or a date-line6.

Instead of “since the troop rises”, noun phrase “troop rise” is used.b) Insurgent raid kills 22 villagersMost headlines use the present tense-despite the fact that they generally describe past events. The present tense gives the subject a sense of freshness and immediacy, making it more intere sting to read. Instead of using “killed”, “kills” is used to describe what happened in the past. Besides, the article “An” in “an insurgent raid” is omitted.c) Bangladesh Sets Curfew To Curb Student ProtestsShort words (i.e. midget words) are often used to conserve space in headlines, for example, “curb” in this headline. Besides, present tense “sets” is used to describe a past event.d) Storm Death Toll in Midwest Climbs1. Compact noun phrases are often used in headlines to save space.2. Most headlines use the present tense-despite the fact that they generally describe past events.e) Wall Street slightly lower as credit worries lingerRhetoric devices often used in the writing of newspaper headlines.In this headline, Wall Street refers to the stock exchange, which is a metonymy. Another rhetoric device used here is rhyme (Correspondence of terminal sounds of words or of lines of verse), as we find in lower and linger.f) China launches crackdown on inferior goods, unsafe foodIn order to conserve space in headlines, comma is sometimes used to replace “and”.g) China to become U.S. third largest export market by yearendIn phrase headlines, infinitives are sometimes used to indicate a future action or event.7.

Many part-time and temporary workers are more likely to bearthe brunt of a job drought because many companies lay them off first.11. Many states will be under pressure to tighten up eligibility ruleseven further because they have allowed their unemploymentinsurance reserve funds to run down in recent years, when the good times seemed to make them less urgent. With unemployment rising again, fewer workers are paying into the system just as more former workers need to take money out. 12.

Girls are closing the gender gap by taking more rigorous math and science classes. SAT scores are up from two decades ago. More and more kids are going to college.14. The way society viewed teens shifted dramatically around thetime of the Great Depression. Before then, teens worked and were considered virtually grown up. But facing a workplace without jobs, Depression youth turned to education as a consolation prize. As high school attendance rolls swelled, the status of teens as full-fledged members of society declined. Now that they were students rather than workers, they came to seem younger than before.15. What’s distinctly different for today’s teenagers, experts say, isthe level of cultural negativity they’re exposed to, from theover-the-top sexuality in advertising, television, and film, to the prevalence of gun violence and family dysfunction. Their exposure to risk is so far beyond what other generations have dealt with.16. Family plays a very important role in helping children overcomethe stresses.

And one in four companies reports firing someone for improper e-mail use.2. Heidi Arace and Norma Yetsko distributed via office e-mail what they thought was fun to share, which their bosses found offensive enough. As a result, the two longtime workers were fired.3. Reasons why companies monitor their workers’ computer use include:- to see to it that workers waste less time online and work more efficiently;- to avoid legal trouble;- to guarantee the security;- to avoid the leakage of sensitive information.4. Companies are using two types of spying software: network-based programs that monitor all traffic passing through a system, and programs that sit directly on an employee’s desktop.5. They should know the company’s computer-use policy and comply with it. They should assume they’re being monitored, and behave accordingly. They should never bad-mouth the company online. They should not use personal e-mail accounts or post to a blog. They should avoid transmitting any message that could embarrass themselves or others if made public. They should not think instant messaging is less permanent than e-mail. When surfing the Web, they should never click on something flagged NSFW (not safe for work).作业六：文艺体育、企业经济、社会问题Lesson 28Answers to the questions1. C2. A3. B4. A5.

The data show that roughly half of the gang members hadbeen involved in a drive-by shooting, 80% carried a concealed weapon and 50% reported taking guns to school.7. Successful intervention programs must aim at boys at this stage.8. The author believes that the society can help some of the gang members to turn over a new leaf by offering them decent regular jobs. One if four gang members said that they would quit the business for a regular wage of $6-7 an hour.Additional Reading1. He shot and killed two people about 7:20 a.m. in West Ambler Johnston Hall.
