B Procedures and Methods
Eight teaching periods are needed to cover the present unit.
1. Period One and Period Two:
●Step One:
a. Background information:
Most westerners begin dating in their early teenage years. Young people often go out in groups and meet at school dances or house parties. After dating a number of different partners, many teenagers begin “going out with” or “seeing” one special person at about 16 or 17. The three most popular first dates for those over 20 are lunch, dinner or a movie. People are staying single longer than before. First-time brides are usually around 26 and grooms are about 28.
b. warm-up questions
At what age did you start dating?
How do you like your dating experiences?
What is your parents’ attitude toward teenagers’ dating?
(The warm-up exercise shall not take up more than 8 minutes.)
and explain language points meanwhile.
Questions about Para. 1
(1) What kind of teenagers were the girl and the boy in this story?
(2) What did they want to do while dating for six months?
(3) What was it that they were too shy to do?
Notes of Para 1:
so:连词，意同also.So引导的子句是倒装句。正常的语序应该是：…and my boyfriend was so(also a shy teenager.)
e.g. (1) My father is a teacher, so is my mother. 我的父亲是老师，我的母亲也是老师。
(2) My father teaches English, so does my mother. 我的父亲教英语，我的母亲也教英
语。
在例（2）中，谓语动词teach属于do一类的动词，而不是be类动词，所以连词so后面用的是does。
date: 当date用作动词时，意为安排社交约会。这个非正式的用法，在美式英语中尤为多见。在本句中date是不及物动词的用法，但是它也可用作及物动词。
e.g. She’s been dating him for months but it’s still not very serious. 她跟他约会几个月了，但
他们的关系还不是很认真的。
Date也可以用作名词或动词。作名词时，它的意思是“提前预约的，异性之间的社交约会，幽会”。
e.g. My parents would not allow me to go out on dates.我的父母不会同意我出去与异性约
会的。
此外，date还有“日期，年、月、日”的意义。
in particular: especially尤其，特别
e.g. What kind of books do you like in particular? 你有什么特别喜欢的书吗？
particular在这里是个名词，表示详情，细目等。particular更通常地被当作形容词使用，表示“特殊的，特别的”。
e.g. There is nothing in the letter of particular importance. 信里没有什么特别重要的事。come close to: get near to a point where something may happen 接近，将要e.g.
(1) Tom came close to falling off the high wall. 汤姆差点从高墙上掉下来。
(2) The child came close to being run over by the bus. 那个孩子差点被公共汽车碾死。
通常这个动词短语的意思是“离……只差一小段距离”。
e.g. The boat came close to the shore. 船快靠近岸了。
to在词组came close to中是介词，因此，跟在come close to后的动词应该是动名词，而不是不定式。
make the first move：to be the first to take action首先采取行动
e.g. (1) At long last he made the first move and asked the girl to agree to marry him. 他最终
首先采取行动，请求女孩同意嫁给他。
(2) They waited for the enemy to make the first move. 他们等待敌人首先采取行动。
Questions about Para. 2
(4) Who made the first move?
(5) When and where did the boy do it?
(6) How come the boy kissed only the cushion instead of the girl?
Notes of Para 2:
go for:to attempt to have or achieve sth 试图得到或完成某事
e.g. (1) He goes for the world record. 他想创世界纪录。
(2) I hear you are going to go for that job in the accounting department. 我听说你要争取财务部的那个职务。
lean vt. & vi.：to be in a sloping position, bend; rest on sth. in a sloping position for support, depend on（使）某物靠在另一物上；靠，屈身；斜，倾斜；依靠，倚。本句lean用作不及物动词。
e.g. (1) Lean forward for a while.向前屈身，并保持一段时间。
(2) A boy is leaning against the wall. 一个男孩倚着墙壁。
当然lean 还有作及物动词的用法。
e.g. (1) The farmers leant their spades against the wall. 农民们把铁锹靠在墙上。
(2) I…leaned him back over his stool…. and kissed him with my most assertive kiss. 我
把他朝凳子往下一摁，送上了我最有冲劲的一吻。(见Note 28)
forward：ad. to the front 向前，朝前方
e.g. (1) When you are driving a car you must look forward. 开车时要向前看。
(2) Please move your car forward. 请你把汽车住前开。
block:vt. to prevent (sb/sth) from moving or progressing, hinder 堵塞, 阻塞
e.g. (1) The accident blocked the traffic. 事故阻塞了交通。
(2) The road was blocked by a downfallen tree. 路面被一棵倒下的树阻堵了。
block:n. [C]a group of buildings bounded by streets on four sides; large piece of wood, stone, etc.; thing that makes movement or progress difficult or impossible, obstruction, obstacle; 街区；大块（木料、石料、金属或冰）或障碍物
Question about Para. 4
(7) What did the girl say after the boy’s moves?
Notes of Para3-4:
must have had: 情态动词must + 动词不定式完成体表示对过去的已经发生过的动作或
事件的一种非常肯定的推测。
e.g. (1) He must have gone to the United States. 他一定去美国了。
(2) He must have been in this room, for his coat is still here. 他一定在这屋子里呆过，因
为他的外衣还在这里呢。
(3) She must have had the flu. That’s why she had a fever and a runny nose. 她一定感冒
了，因为她发烧，还流鼻涕。
(4) It must have rained last night, for the ground is wet. 昨天一定下雨了，因为地上还是
潮湿的。
leaning against the wall with my arms crossed…: leaning这个现在分词短语被用作方式状语来修饰谓语动词词组walked (over) and stood (there)。
with my arms crossed: 这是with + noun + 过去分词的结构。
e.g. The magician escaped from the cage with his hands tied behind his back. 魔术师的双
手反绑着，从笼子里逃了出来。
Questions about Paras. 5-6
(8) What did the girl do when she was waiting for her boyfriend to give her the kiss?
(9) What actually happened to the boy’s last attempt?
Notes of Paras 5-8:
stand tall：一些动词如stand, sit, die可以与形容词连用构成复合谓语，这些动词属于连系动词（见本单元Focus 3:Grammar Review）。本句中的复合谓语stood tall 可以理解为由两个句子合成而得: I stood and I was tall.
e.g. (1) He died heart-broken. 他心碎而死。
(2) She sat still all the time.她一直一动不动地坐着。
come at:to reach, attain to, get access to够到
e.g. (1) I saw the ball on the tree, but it was too high for me to come at. 我看到球在树上，但
太高了，我够不着。
(2) Put the bottle on the shelf, where the kid can’t come at. 把瓶子放在书架上，那里孩
子够不到。
这个词组也可用来表示attack sb.
e.g. (1) She came at me with a stick. 她手持棒子朝我扑来。
(2) A tiger is coming at the farmer. 一只老虎扑向农夫。
right: ad. 当right 用作副词时，表示强调。e.g.
(1) Where is my pen? It is right there. 我的笔在哪里？就在那里。
(2) The park is right in the center of the city. 公园就在城市的中心。
could have died: 这同样是情态动词加不定式完成体的结构。但是不像must have had结构，本结构不表示一个动作已经完成或一件事已经发生。本结构用于虚拟语气中，表示一个动作，一件事或一个状态其实并没有发生或者并不存在。could have died并不是我的死亡是已经发生的事实，说话者并没有死。
e.g. (1) I could have achieved much more successes if I had listened to your advice earlier. 如
果我早一点听你的劝告的活，我可以取得更大的成功。（事实上，我取得的成功不大。）
(2) He could have arrived in time but for the bad traffic. 要不是交通状况不好的话，他
可以准时到达的。（事实上: 他没有准时到达）。
Question about Para. 9
(10) Did the girl have another date in the next two years in her high school after this
incident?
Notes of Para 9:
wonder: vt. to feel curious (about sth); feel great surprise, admiration etc. 感到好奇或十分惊讶，赞赏等等。这个动词通常引导出一个wh从句，作为它的宾语。
e.g. (1) I wonder why the dog is barking. 我不知道这条狗为什么在吠叫。
(2) Wondering who’s knocking at the door, Mary got scared. 不知谁在敲门，玛丽感到害
怕。
Wonder也可以用作名词，表示惊奇，惊异；奇迹，奇事，奇观
abandon：vt. leave someone or something; give up; desert 离弃；放弃；抛弃
e.g. (1) The man abandoned his wife and child. 这个人遗弃他的妻子和孩子。
(2) They had abandoned all hope. 他们放弃了一切希望。
cause：vt.to make happen使发生。
e.g.(1) The cold weather caused me to cough.天气冷得让我咳嗽了。
(2) The difficulty caused him to give up. 困难使他放弃了。
cause也可用作名词，表示原因，起因，理由；事业（奋斗的）目标。
Question about Para. 10

Notes of Para 10: determined /wonder/ awkward/ not…any longer
Questions about Para. 11-12
(12) What did the girl do when she happened to meet her first boyfriend in a karaoke bar in
the spring?
(13) Who was sitting next to the man?
(14) What was the girl’s name in this story?
Notes of Para 11-12:
Suppose: vt. think that something is true when one is not totally sure 猜想；料想
e.g. (1) It’s late, so I suppose I must go home. 挺晚了，所以我想我必须回家了。
(2) What do you suppose (think)happened next? 你猜后来发生了什么事情？
do you suppose：这是个插入成分。这个句子可以理解为由以下两句句子组成：“Who do I see sitting at the bar, but my old kissing partner?” + “you suppose”.
pat him on the shoulder：注意pat与介词的搭配：pat …on…. 同样的表达有：hit (knock)
sb. on the nose (打在某人的鼻子上); tap sb. on the shoulder（拍拍某人的肩膀）, stab sb. in the back（背后行刺某人）等。
pat也可用作名词，表示轻拍，轻打。

1 21 世纪大学实用英语综合教程（第一册）课后答案及课文翻译 Text A 大学——我一生中的转折点 佚名 作为一名一年级新生初进大学时，我害怕自己在学业上搞不好。我害怕独 自一人在外，因为我是第一次远离家人。这里周围都是我不认识的人，而他们也不认识我。我得和他们交朋友，或许还得在我要学的课程上跟他们在分数上进行竞争。他们比我更聪明吗？我跟得上他们吗？他们会接受我吗？ 我很快就认识到，我的生活现在就取决于我自己了。如果我要在学业上取得成功，我就必须制定一份学习计划。我必须调整花在学习上的时间和花在社交上的时间。我必须决定什么时候上床睡觉，什么时候吃什么，什么时候喝什么，对什么人表示友好。这些问题我都得自己回答。 开始时，生活有点艰难。我在怎样利用时间上犯了错误。我在交朋友上花的时间太多了。我还在怎样选择大学里的第一批朋友上犯了一些错误。 然而不久，我就控制住了自己的生活。我做到了按时上课，完成并交上了第一批作业，而且以相当好的成绩通过了前几次考试。此外，我还交了一些朋友，跟他们在一起我感到很自在，我能把我担心的事告诉他们。我建立了一种真正属于我自己的常规——一种满足了我的需要的常规。 结果，我开始从一个不同的视角看待我自己了。我开始把自己看作是一个对自己 2 负责也对朋友和家人负责的人。凡事自己做决定并看到这些决定最终证明是明智的决定，这种感觉很好。我猜想这就是人们所说的“成长”的一部分吧。 我未来的生活将会怎样呢？在人生的这一阶段，我真的不能确定我的人生之路最终将会走向何方，我真的不知道在以后的几年中我会做什么。但我知道，我能应对未来，因为我已经成功地跃过了我生命中的这一重要障碍：我已经完成了从一个依赖家人给予感情支持的人向一个对自己负责的人的过渡。 Practice 5 1. smart 2. succeed 3. shortly 4. managed 5. share 6. fear 7. responsible 8. however 9. enter 10. surrounded 11. handle 12. comfortable Practice 6 1. is up to 2. keep up with 3. under control 4. at first 5. grew up 6. make friends with 7. turned out 8. as a result 9. set up 10. in addition Practice 7 1. how to play the game 2. where I wanted to go 3. whether they would accept him or not 4. what to do and how 3 to do it 5. whom to love and whom not to 6. when he made that decision Practice 8 1.

上海交通大学考研复试流程全攻略 问题一：何时联系导师？ 解答：如果自己分数比较有把握可以现在发邮件联系导师，表达自己想追随导师的愿望，此阶段不推荐直接拜访老师。初试成绩出来后，分数较往年复试线高出一定分数时，基本可以直接发邮件或打电话给导师，询问导师招生名额是否招满，再次表达愿望。如果你的分数确实比较可以，导师没有招满的话，基本导师就会要你。另外初试成绩在往年复试线徘徊的同学，一方面也可以联系导师，另一方面要准备好调剂的准备。如果这时有导师特别欣赏你，比如你本科就有科研经历，这时要及时和导师沟通。 问题二：如何选择自己中意的导师？ 解答：因人而异。如果你特别喜欢做学术，而且你自己实力也很强，那推荐联系学院比较有威望的导师。如果你只想硕士毕业即可，学术兴趣不强，推荐你联系学院一般的导师即可，不推荐太年轻的导师。太年轻的导师能拿到的课题不多，但是现在交大可存在这样一种情况，年纪轻的导师一般跟在学院有实力的导师下面做事，因此也是有部分课题的。而且很可能你报考本来比较有威望的导师，但是此导师已经被交大自己学生选择，那么你很可能被调剂到此导师团队中别的导师。无论跟随什么的导师，请相信交大导师的能力，既然有资格带你，就不会差，最终什么都还得靠自己的！
问题三：考研成绩何时公布? 解答：上海交大考研成绩一般在三月初公布，最晚三月中旬。复试和初试成绩公布一般相隔半个月，具体因学院而异。 问题四：如何准备复试？ 解答：上海交大各个学院每年都会公布复试方案，此方案在学院网站中有下载，大家可以参考往年复试方案进行复试。通常往年有笔试的专业，基本上还是看本科的书，考的都是本科专业课中比较重要的几门课，知识点都较基础。没有笔试的专业，基本也是看书，因为面试提问也是这些基础知识。当然，如果你的分数高达400多分，那你基本可以高枕无忧，因为面试的时候导师不会问你基础问题，而是问你通常都有什么兴趣爱好，跟你唠家常。复试基本没资料，考验的就是大家心里素质和专业基本功。 问题五：复试是不是真的很重要？ 解答：这个问题至少目前来看，复试不是特别的重要，复试只是响应教育部的政策，落实下来基本每个学校都是走过场，当然工科基本是这样，文科那边基本走过场和较真格各一半一半吧，谁让别人文科专业吃香呢。在大家复试之前，基本上已经确定了大家何去何从，刷人就是靠初试分数，排名靠后的基本都会被刷掉，所以如果你的分数基本在复试线边缘上，一方面好好准备复试，一方面准备好调剂，为什
新编实用英语综合教程1第四版课文翻译There is no perfect way for human beings to deal with cockroaches up to now. There is an instrument in Europe that can emit a specific frequency wave similar to that in a microwave oven, rapidly raise the blood temperature in the cockroach's body and instantly cause the cockroach to blow itself up. However, even if it is applied in such a wide range, it cannot completely eliminate the cockroach. Moreover, it can kill any organism containing water in the body and was banned several years ago. I do not recommend you to use any insecticide, which can only kill some cockroaches. It is an indisputable fact that cockroaches cannot be completely eliminated, but it can accelerate the evolution of cockroaches. The same insecticide may be used for one to two years, and cockroaches will be immunized against this insecticide by producing antibodies themselves. If you kill a limited number of cockroaches, the evolution of cockroaches will be accelerated permanently. Suggested methods are as follows: 1. Overcome your fear of cockroaches. 2. Use aggressive weapons to cause physical damage to cockroaches to death. (For example, newspapers, flyswatters.) 3. Clean the house and keep the house clean all over the world to minimize the living space of cockroaches. Finally, I give you advice: if you find a cockroach in the room, you think there are more than 200 cockroaches nearby. The number of cockroaches on the

上海交通大学考研心得 途中多有波折，经历了许多，也成长了很多。以前做事坚持不下来，但是在同学和长辈们的鼓励和支持下，虽然不断地想放弃，还是坚持了下来，所以坚持就 ...这里给大家分享一些关于考研心得体会，供大家参考。 考研心得体会1 先说一下我的情况，我是12年毕业于中部一所985，学的专业是工科，在南方工作了2年感觉这辈子要是就这么个混法，算是完了。在14年的时候反复思量，最后走上考研道路的，8月份正式复习，大学时学的那点皮毛早就忘的一干二净，也算是零基础吧。 考研首先是定目标。非要我说说为什么考金融，倒也直率简单，因为本身是学工科的，结合我的经历认为，金融高大上，工科纯屌丝,就走上了这么个道路，当然了，这种想法是对我个人而言，很片面也很短视。 择校择专业 再就是选学校。一开始想着去央财或者是上财，后来想想不怎么好，本身985考个211的金融，觉得特别怂，打听到安泰431偏好理工科，往年的招生名额也都十来个，就这么下了决定。事实上，安泰431确实欢迎理工科的学生跨考，这点我在后面还要说。招生名额后来变化比较大，大家都知道的，今年新的推免政策，一下子把统考名额减少了近三分之二，这也导致了今年有同学报841的没能如愿调剂成功。 初试时间安排 8月份开始我在南方一所高校附近租房，每天去别人的图书馆蹭自习室，7点半
起床，晚上10点半回去，再背一会单词和专业课，期间也午休，午饭和晚饭一个小时，每天的学习时间在12个小时左右，一周休息半天，除了去现场报名外，没有间断过，算得上有始有终。由于是陌生的学校，不认识人，每天说的话就是跟饭堂的阿姨点菜，考研的辛苦在现在看来倒还让人怀念，其中的滋味只怕是过来人才能深有体会。 英一70+，政治70+，数一120+，专业课110+，复试完后才知道这个初试成绩在今年还是排名靠前的，考虑到交大431压分，四科中我唯一考后不遗憾的就是专业课了，加上其他公共课有很多高人的经验，我就说说作为一个0基础，没有一点金融学基础知识的考生是怎样复习专业课的吧。 参考书 参考书目：货币银行学 (第三版，戴国强主编)，公司理财 (第9版，罗斯著)，《罗斯《公司理财》笔记和课后习题详解》(中国石化出版社)，《金融硕士(MF)真题及详解》(机械工业出版社)，网上下载的各金融名校近年真题。(交大431官方其他2本教材完全不用看)。 首先是打基础。刚开始的时候，每天从7点以后的时间我都分配给了专业课，先看货币银行学，关键是背，背的时候要理解着背才会深刻，这里的背不是通遍背，书中大部分文字都是对一些原理的解释，这部分是理解到能用自己的话说出来即可，成功的背诵我想是应该能对着课后习题，完整地回答所有的问题;能不用看书，把这一章从节到各节的二级标题框架勾勒出来;能把各二三级标题的主要内容表述出来。 前两遍较慢，用两个小时有时都搞不定一章，每天在背下一章的时候都会先把前一章的内容复习一遍，反复加强，即使如此，背3遍可能还是觉得都忘了，我前后背了7遍，第5遍的时候才达到看个章节标题就能复述全文的地步。这样的背书我是采用不出声的方式，从没有间断过。
工程流体力学习题解析(夏泰淳_著)_上海交通大学出版社 第1章绪论 选择题 【】按连续介质的概念，流体质点是指：（）流体的分子；（b）流体内的固体颗粒；（c）几何的点；（d）几何尺寸同流动空间相比是极小量，又含有大量分子的微元体。 解：流体质点是指体积小到可以看作一个几何点，但它又含有大量的分子，且具有 诸如速度、密度及压强等物理量的流体微团。（）【】与牛顿内摩擦定律直接相关的因素是：（）切应力和压强；（b）切应力和剪切变形速度；（c）切应力和剪切变形；（d）切应力和流速。 解：牛顿内摩擦定律是，而且速度梯度是流体微团的剪切变形速度，故。 （） 【】流体运动黏度υ的国际单位是：（）m2/s；（b）N/m2；（c）kg/m；（d）N·s/m2。 解：流体的运动黏度υ的国际单位是。（） 【】理想流体的特征是：（）黏度是常数；（b）不可压缩；（c）无黏性；（d）符合。 解：不考虑黏性的流体称为理想流体。（） 【】当水的压强增加一个大气压时，水的密度增大约为：（）1/20 000；（b）1/1 000；（c）1/4 000； （d）1/2 000。 解：当水的压强增加一个大气压时，其密度增大约。 （） 【】从力学的角度分析，一般流体和固体的区别在于流体：（）能承受拉力，平衡时不能承受切应力；（b）不能承受拉力，平衡时能承受切应力；（c）不能承受拉力，平 衡时不能承受切应力；（d）能承受拉力，平衡时也能承受切应力。 解：流体的特性是既不能承受拉力，同时具有很大的流动性，即平衡时不能承受切 应力。（）【】下列流体哪个属牛顿流体：（）汽油；（b）纸浆；（c）血液；（d）沥青。 解：满足牛顿内摩擦定律的流体称为牛顿流体。（）【】时空气和水的运动黏度，，这说明：在运动中（）空气比水的黏性力大；（b）空气比水的黏性力小；（c）空气与水的黏性力接近；（d）不能直接比较。 解：空气的运动黏度比水大近10倍，但由于水的密度是空气的近800倍，因此水 的黏度反而比空气大近50倍，而黏性力除了同流体的黏度有关，还和速度梯度有 关，因此它们不能直接比较。（）【】液体的黏性主要来自于液体：（）分子热运动；（b）分子间内聚力；（c）易变形性； （d）抗拒变形的能力。 解：液体的黏性主要由分子内聚力决定。（） 计算题 【】黏度μ=×10﹣2Pa·s的黏性流体沿壁面流动，距壁面y处的流速为v=3y+y2（m/s），试求壁面的切应力。 解：由牛顿内摩擦定律，壁面的切应力为 【】在相距1mm的两平行平板之间充有某种黏性液体，当其中一板以s的速度相对于另一板
