一、1.失败是常有的事。2.人们对失败有各种态度。3.我对失败的态度。题目：失败是常有的事

Failure is a common thing

There are all kinds of setbacks in our life.Facing different challenges, sometimes we succeed, and sometimes we don’t.In fact, it’s more common that we fail in the very first few attempts.However, different people hold different opinions on failure: some people won’t get frustrated by failure and persisted in carrying out their attempts, while the others give up easily after a few attempt.There is no absolute right or wrong in these attitudes.In my opinion, failure is not a bad thing and we should not get frustrated by it.What is more important is to learn something from it and behave better next time.有各种各样的挫折，在我们的生活中。面对不同的挑战，有时我们会成功，有时我们不。事实上，这是更常见的，我们不能在最初的几次尝试。然而，不同的人持不同意见的失败：有些人不会失败，坚持他们的企图，而其他人轻易放弃后的一些尝试。没有绝对的对或错在这些态度。在我看来，失败不是一件坏事，我们不应该气馁的。更重要的是从中吸取点教训，下次会表现得好些。

二、1.很多的大学生毕业后留在大城市工作；2.也有人选择到小城镇开始自己的职业生涯；3.结合自己的实际情况谈谈自己的想法。

题目：职业生涯开始在大城市或小城镇

Occupation career began in a big city or small town

Plenty of students decide to stay in big cities after graduation, becoming a member of the fast-paced big city.Meanwhile, some students start their career in small towns, enjoying the easy life there.In my opinion, both choices have advantages and disadvantages: in big cities, there are more job opportunities, more fashionable products and more wonderful night-life for us young people, but the fast-paced life and high consumption level can easily make us tired and exhausted;on the contrary, in small town, the easy and slow-paced life there will make people more comfortable, but there are fewer work positions and less entertainment.To me, first of all, a good job is the most important thing when I making my choice, regardless of big city or small town.Secondly, I intend to go back to my hometown Wuhan, which is a big city.Anyway, no matter where you work, you should always work hard on your job, which is the most important thing.很多的大学生毕业后决定留在大城市，成为会员的快节奏的大城市。与此同时，一些学生开始他们的职业生涯在小城镇，享受简单的生活。在我看来，两种选择都有优点和缺点，在大城市，有更多的就业机会，更时尚的产品和更精彩的夜生活为我们的年轻人，而这种快节奏的生活和消费水平高也很容易使人精疲力竭的；相反，在小城镇，容易和缓慢的生活会让人更舒适，但也有少少的工作岗位和娱乐。对我来说，首先，一个好的工作是最重要的事情时，我做了我的选择，无论是大城市还是小城镇。其次，我要回到我的家乡武汉，这是一个大城市。总之，不管你在哪里工作，你都应该努力工作，这是最重要的。

三、1．良好的饮食习惯有什么好处。2．举例说明哪些属于良好的饮食习惯。

题目：良好的饮食习惯

Good Eating Habits

possibility of decease.Thirdly, eating a well-balanced diet will give us enough nutrition to operate all the body physical function normally.In a word, these good eating habits can improve our general state of health and help us lead a longer and healthier life.好的饮食习惯可以帮助我们活得更长、更健康的生活。首先，慢慢吃，会给我们更多的时间去消化食物和减少风险的吞咽过多的食物在膳食。其次，洗手之前和之后的每餐都会让我们远离大多数细菌在空气和减少的可能性，去世。第三，吃均衡的饮食习惯会给我们足够的营养来经营的所有身体功能正常。总之，这些良好的饮食习惯，可以提高我们的一般健康状况和帮助我们领导更长和更健康的生活。

四、1.大家都需要友谊；2.什么是真正的。友谊；3.如何交朋友。

题目：友谊

Friendship

As everyone need friendship, keeping a steady friendship with other people is one of the basic demands of human beings, especially the true friendship.In the modern society, people always hunt for true friendship which becomes rarer and rarer eventually.A true friendship goes with honesty and loyalty, and a real friend will not judge the friendship by social position or properties, who will not betray you in any situation.Therefore, when you make friends with people, be careful and considerate, thinking of things in other people’s position.This way you’ll gain true friends.人人都需要友谊，保持稳定的友谊与其他人是人类的基本需求，尤其是真正的友谊。在现代社会里，人们一直在寻找真正的友谊而变得稀少最终。真正的友谊是诚实和忠诚，和一个真正的朋友会判断不是友谊的社会地位或性质，谁不会背叛你在任何情况下。因此，当你与人交朋友，要细心体贴，思考的事情在其他人的位置。这样你会获得真正的朋友。

五、世界上每天都有成千上万的人死于车祸；2.司机不注意自己的驾车行为；3.应该制订法律防止车祸发生。

题目：只有制定更严格的法律才能防止事故

Only Stricter Traffic Laws Can Prevent Accidents

Everyday there are thousands of people die of traffic accidents in the world.The main reason is because the drivers don’t pay enough attention to their driving behavior.They receive phone call when they are driving, which will distract them and thus cause their slow reaction to the unexpected traffic condition, like overtaking, slowdown suddenly and so on.Some drivers drive after drinking alcohol, which is also very dangerous and should be forbidden by law.Therefore, we should reenact laws to prevent this kind of traffic accidents.每天有成千上万的人死于交通事故在世界上。主要的原因是因为司机不支付足够的重视他们的驾驶行为。他们接电话时，驱动，将他们的注意力，从而使他们的反应缓慢的意想不到的交通条件，如突然超车，减速等。有些司机酒后驾车，这是非常危险的，应被法律所禁止。因此，我们应该制定法律来阻止这种交通事故。

六、1.健康的重要性；2.不健康的生活习惯有……3.如何保持健康。

题目：健康

Health

Health is very important in our life, as it's the base of our work and activities.Without a healthy body, we can’t work or study at all.Drinking too much alcohol, smoking, staying overnight, irregular meal, are all unhealthy habits in our life.These behaviors will cause aging and weakness of our body, which should be changed as soon as possible.In order to keep healthy, we should keep us away from drinking and smoking problem and insist on regular sleeping and meal time.健康是我们生活中非常重要的，因为它的基地的工作和活动。没有健康的身体，我们也不能工作或研究在所有。酗酒，吸烟，过夜，不规则的饮食，都是不健康的生活习惯。这些行为将导致老化和虚弱的身体，应尽快改变。为了保持健康，我们应该保持我们远离饮酒和吸烟问题，坚持定期睡觉和吃饭的时间

第二篇：2014华工网络土木工程材料作业--答案

一、问答题。

1．常见合成高分子防水卷材有哪些？ 答：

1)橡胶类有：三元乙丙卷材、丁基橡胶卷材、再生卷材等； 2)塑料类有：聚氯乙烯卷材、氯化聚乙烯卷材、聚乙烯卷材等； 3)橡塑类有：氯化聚乙烯、橡胶共混卷材。

2．钢材牌号与其强度质量等的关系？

答：钢的牌号由代表屈服点的字母、屈服点数值、质量等级符号、脱氧方法符号等四个部分顺序组成。牌号越大，含碳量越大，抗拉强度越高，而伸长率则随着牌号的增大而降低。

3．各元素对钢材质量的影响？

答：钢材中除了主要化学成分铁以外，还含有少量的碳、硅、锰、磷、硫、氧、氮、钛、钒等元素： 1)碳（C）：

a)所有碳素钢的性能主要取决于含C量，钢中含碳量增加，屈服点和抗拉强度升高，但塑性和冲击性降低，0。8%以下的碳钢抗拉强度与含碳量成正比增加，塑性及韧性则相反，含C量>0。8%的碳钢，强度及塑性均低，但硬度很高，但当含碳量在1。0%以上，随着含碳量的增加，钢材的强度反而下降。所以含C量不同的钢经处理后显示的性质就不同。含碳量越高，钢的硬度就越高，但是它的可塑性和韧性就越差。碳量高还会降低钢的耐大气腐蚀能力，在露天料场的高碳钢就易锈蚀。

b)随着含碳量的增加，钢材的焊接性能变差（含碳量大于0。3%的钢材，可焊性显著下降），冷脆性和时效敏感性增大，耐大气锈蚀性下降。一般工程所用碳素钢均为低碳钢，即含碳量小于0。25%；工程所用低合金钢，其含碳量小于0。52%。

2)、硅（Si）：

a)在炼钢过程中加硅作为还原剂和脱氧剂，是钢中的有益元素。所以镇静钢含有0。15－0。30%的硅。如果钢中含硅量超过0。50-0。60%，硅就算合金元素。硅含量较低（小于1。0%）时，能提高钢材的强度，而对塑性和韧性无明显影响。它可以提高钢的硬度，但是可塑性和韧性下降，电工用的钢中含有一定量的硅，能改善软磁性能。

b)硅能显著提高钢的弹性极限，屈服点和抗拉强度，故广泛用于作弹簧钢。在调质结构钢中加入1。0－1。2%的硅，强度可提高15－20%。

c)硅和钼、钨、铬等结合，有提高抗腐蚀性和抗氧化的作用，可制造耐热钢。d)含硅1－4%的低碳钢，具有极高的导磁率。e)硅量增加，会降低钢的焊接性能。

3)锰（Mn）：

a)锰是炼钢时用来脱氧去硫而存在于钢中的，是钢中的有益元素。锰具有很强的脱氧去硫能力，能消除或减轻氧、硫所引起的热脆性，大大改善钢材的热加工性能，同时能提高钢材的强度和硬度。一般钢中含锰0。30－0。50%。在碳素钢中加入0。70%以上时就算“锰钢”，较一般钢量的钢不但有足够的韧性，且有较高的强度和硬度，提高钢的淬性，改善钢的热加工性能，如16Mn钢比A3屈服点高40%。

b)锰量增高，减弱钢的抗腐蚀能力，降低焊接性能。锰是我国低合金结构钢中的主要合金元素。能提高钢的强度，能消弱和消除硫的不良影响，并能提高钢的淬透性，含锰量很高的高合金钢（高锰钢）具有良好的耐磨性和其它的物理性能。

4)磷（P）：

a)在一般情况下，磷是钢中有害元素，随着磷含量的增加，钢材的强度、屈强比、硬度均提高，而塑性和韧性显著降低。特别是温度愈低，对塑性和韧性的影响愈大，显著加大钢材的冷脆性。磷也使钢材的可焊性显著降低。因此通常要求钢中含磷量小于0。045%，优质钢要求更低些。

b)但磷可提高钢材的耐磨性和耐蚀性，故在低合金钢中可配合其他元素作为合金元素使用。能使钢的可塑性及韧性明显下降，特别的在低温下更为严重，这种现象叫做冷脆性。c)在优质钢中，硫和磷要严格控制，但另方面，在低碳钢中较高的硫和磷，能使其切削易断，对改善钢的可切削性有利。

5)硫（S）：

a)硫是钢中很有害的元素。硫的存在会加大钢材的热脆性，降低钢材的各种机械性能，也使钢材的可焊性、冲击韧性、耐疲劳性和抗腐蚀性等均降低。是钢中的有害杂物，含硫较高的钢在高温进行压力加工时，容易脆裂。通常叫作热脆性。b)硫对焊接性能不利，降低耐腐蚀性。

6)氧：氧是碳素钢中的有害杂质。含氧量增加，使钢的机械强度降低、塑性和韧性降低，促进时效作用，还能使热脆性增加，焊接性能变差。

7)氮：氮能使钢的强度提高，塑性特别是韧性显著下降。氮还会加剧钢的时效敏感性和冷脆性，使可焊性变差。在钢中氮若与铝或钛元素反应生成的化合物能使晶粒细化，可改善钢的性能

4．加气混凝土砌块的特点？ 答：

1)质轻； 2)保温隔热； 3)加工性好； 4)利废。

5．常见的热固性塑料有哪些？ 答：

1)酚醛树脂； 2)氨基塑料； 3)环氧树脂；

4)玻璃纤维增强塑料； 5)有机硅树脂。

6．什么是屈强比，对选用钢材有何意义？ 答：屈服强度与强度极限之比称为屈强比。当这个比值较小时，表示结构的安全度较大，即结构由于局部超载而发生破坏的强度储备较大，但比值过小时，则表示钢材强度的利用率偏低，不够经济。相反若屈强比较大，则表示钢材利用率较大，但比值过大，表示强度储备过小，脆断倾向增加，不够安全。因此这个值最好保持在0。60～0。75之间，既安全又经济。

7．造成硅酸盐水泥体积安定性不良的原因有哪些？怎样检验？

答：熟料中所含的游离氧化钙、游离氧化镁或掺入的石膏过多；游离氧化钙引起的安定性不良可采用试饼法或雷氏法检验，在有争议时以雷氏法为准，氧化镁和石膏的危害作用不便于快速检验，因此常在水泥生产中严格加以控制，国标规定水泥中游离氧化镁质量分数不超过5%，三氧化硫质量成分数不超过3。5%。

8．如何利用维勃稠度仪测量混凝土拌合物的维勃稠度值？（要求写出测定步骤）

答：

1)把仪器放在坚实水平的平台上，用湿布把容器、坍落度筒、喂料口内壁及其它用具湿润。就位后将喂料口提到坍落度筒上方扣紧，校正容器位置，使其轴线与喂料口轴线重合，然后拧紧蝶形螺母；

2)把按要求取得的混凝土试样用小铲将料分三层装入坍落度筒内，每层料捣实后约为高度的三分之一，每层截面上用捣棒均匀插捣25下，插捣第二层和顶层时应插透本层，并使捣棒刚刚进入下一层顶层，插捣完毕后刮平顶面；

3)使喂料口、圆盘转离，垂直地提起坍落度筒，此时并应注意不使混凝土试样产生横向扭动；

4)把透明圆盘转到混凝土圆台体顶面，放松定位螺丝，降下圆盘，使其能轻轻接触到混凝土表面，读出数值即为坍落度值。同时按控制器“启动／停止”按钮，当震动到透明圆盘的底面被水泥浆部满的瞬间再按“启动/停止”按妞，震动停止，控制器显示数值（时间：单位秒）即为维勃稠度值。

9．有效减少钢材腐蚀的措施？

答：防止钢材锈蚀主要有三种方法：①制成合金钢；②表面覆盖；③设臵阳极或阴极保护。

10．高铝水泥适用于何种工程？

答：主要应用于紧急军事工程、抢修工程等临时性工程；要求早强的特殊工程；耐热混凝土 工程以及冬季施工等工程。

11．花岗岩有何特点？

答：表观密度大；结构致密、抗压强度高；孔隙率小、吸水率极低；材质坚硬；化学稳定性好；装饰性好；耐久性好等。

12．胶粘剂的组成材料有哪些？

答：有粘料、固化剂、填料、稀释剂等。

13．木材强度的特点？

答：结构木材常用的强度有：抗压、抗拉、抗剪和抗弯强度。

1)抗压强度：木材的抗压强度分为顺纹抗压强度和横纹抗压强度，顺纹抗压强度较高，且木材的疵点对其影响较小，在建筑工程工利用最广，常用于柱、桩、斜撑及桁架等承重构件。顺纹抗压强度是确定木材强度等级的依据。2)抗拉强度：也分为顺纹抗拉强度和横纹抗拉强度，顺纹抗拉强度是木材所有强度中最大的，担是木材的疵点对其影响极为显著，因此木材实际的顺纹抗拉能力反较顺纹抗压为低。横纹抗拉强度很低，工程中一般不用。

3)抗弯强度：木材的抗弯强度很高，在建筑工程中常用于地板、梁、桁架等结构中。4)抗剪强度：作用力对木材纤维方向的不同，可分为顺纹剪切、横纹剪切和横纹切断。

14．决定半固体或固体沥青粘滞性的技术指标是什么？ 答：针入度指标

15解释钢号Q235AF、Q235D代表的意义，并比较二者在成分、性能和应用上的异同？ 答：

1)Q235AF表示屈服强度为235MPa，由氧气转炉或平炉冶炼的A级沸腾碳素结构钢。2)Q235D表示屈服强度为235MPa的D级钢。A级钢的S和P含量高于D级钢，但Mn含量低于D级钢，A级钢一般用于承受静载作用的钢结构，D级钢则可用于低温条件下承受动载焊接的重要结构。

16．试述混凝土中的四种基本组成材料在混凝土中所起的作用。

答：四种基本材料是：水泥、砂、石、水；在混凝土中砂、石起骨架作用，称为集料，可以节省水泥；可以降低水化热，减少混凝土由于水泥浆硬化而产生的收缩，抑制裂缝的扩展；水泥与水形成水泥浆，水泥浆包裹在集料表面并填充其空隙，在硬化前，水泥浆与外加剂起润滑作用，赋予拌合物一定和易性，便于施工，水泥浆硬化后，则将集料胶结成一个坚实的整体。

17．何谓减水剂？试述减水剂的作用机理。在混凝土中加减水剂有何技术经济意义？我国目前常用的有哪几种？

答：减水剂：掺入混凝土后，在不改变配合比的条件下，可显著增大混凝土流动性的外加剂；或在保持混凝土拌合物流动性不变条件下，可显著降低用水量的外加剂。混凝土中掺减水剂的技术经济意义：

(1)保持混凝土流动性和水泥用量不变，可降低用水量，增加混凝土的强度；(2)保持流动性和强度不变，可降低用水量，减少水泥用量，降低成本；(3)保持流动性不变，可减少单位用水量，降低混凝土的离析和泌水，提高混凝土的密实性，提高混凝土的抗渗性和抗冻性；(4)可减缓水泥的水化放热速率，利于大体积混凝土中温度应力的降低，从而减少开裂的可能性。

常用减水剂品种：普通型的---木钙(M剂)；高效型----萘系：FDN，NNO，MF等； 水溶性树脂类：SM剂。缓凝型---糖蜜类。18．石油沥青的组分主要有哪几种？各有何作用？

答：主要有油分、树脂和地沥青质三个组分；油分赋予沥青流动性；树脂使沥青具有良好的塑性和粘结性；地沥青质则决定沥青的耐热性、粘性和硬性，其含量愈多，软化点愈高，粘性愈大，愈硬脆。

二、计算题

1．已知实验室配合比为水泥：砂：石=1：2.4：4，W/C＝0.65，混凝土混合物的表观密度ρ0＝2400kg/cm，当日实际测得卵石含水率为2.5％，砂含水率为4％.计算其施工配合比四种材料各为多少公斤？ 解：

 总量：2400*0.805=1932kg 1)水泥用量：1932*1/8.05=240kg 2)河砂用量：240*2.4*1.04=599.04kg 3)卵石用量：240*4*1.025=984kg 4)水用量：240*0.65-240*2.4*0.04-240*4*0.025=108.96kg

2．某石料，浸水饱和后擦干表面并测得质量为640克，烘干后为620.它的密度为2.70g/cm3，表观密度为2.40 g/cm3，.求该材料的孔隙率、质量吸水率、体积吸水率、开口孔隙率、闭口孔隙率和视密度（近似密度）.(假定开口孔全可充满水)解：

1)孔隙率：P=（1-3ρ0ρ）*100%=（1-

2.4）*100%=11.11% 2.7640620*100%=3.23%

6202)质量吸水率：Wm=

m1mm*100%=3)体积吸水率：Wv= Wm*ρ0=3.23%*2.4=7.74% 4)开口孔隙率：20/2.4*100%=3.13%

640/2.45)闭口孔隙率：孔隙率-开口孔隙率=11.11%-3.13%=7.98%

第四篇：华工食品学院英语面试

the most important thing in life is to have a great aim and the determination to realize it!

敬爱的各位老师你们好：

我是来自四川农业大学食品科学与工程专业的刘洪伟，很荣幸能够参加今天的面试，我填报的是食品科学，食品安全方向，所选导师是××教授。我相信我今天能够有好的表现。

我大学的入学成绩仅比重本线高10分，而我们班学习基础好的同学太多太多，我深知与其他同学的差距，三年来我一直在努力，学习总评成绩达到86.7分，专业前茅，我相信努力不一定成功，但不努力一定不会有回报，通过努力，大学三年间我连续三年获得一等奖学金，获得过国家奖学金，大二一年又被给与川农大最高荣誉优秀学生标兵，受到了校长的提名表扬。

大三的专业知识的学习和毕业论文的实验，我越发感到自己对于微生物有浓厚的兴趣，微生物这个神奇的世界吸引了我，而微生物和发酵能够联系在一起，体现了微生物的有用性和极大的挖掘价值，毕业论文我选择的题目是《茅台酒酒酒糟中红曲菌的分离纯化及其酶学性质的研究A primary study on the isolation and identification of 5 fungal strains in moutai distiller’s yeast 》，现在实验已经基本完成。因为了解，所以我更加热爱，如果能够顺利的读上研究生，我希望能够继续研究有关真菌方面的内容，尤其是微生物性食源性污染的研究对于分离纯化鉴定工作和真菌方面的尝试我有较好的掌握。我在大学的三年的本科学习期间，除了牢牢的掌握了专业知识外，我还对计算机和英语也有所造诣，计算机通过了国家三级并且拿到了ps，cad的职业技能证书，英语在写作和听说能力也有很大的进步。我相信在未来 the most important thing in life is to have a great aim and the determination to realize it!的科学研究中一定能够发挥很大作用。

英文版的自我简介：

Ok, well, Good afternoon, dear professors.First of all, I am really appreciated with the opportunity that you give me to join this interview/ it’s my great pleasure to participate in this interview.I am liuhongwei, coming from Sichuan agricultural university.my major is food science and engineering.The major for further education that I purse here is +your major.（介绍自己的学习成绩和奖项，简单点，挑主要的）Well, professor, my average score of compulsory courses in the past three years is 86.7, I also won the First Prize of Excellent Undergraduate Scholarship for three years.Most important of all , I was awarded the tile “ pace-setter”

that just 10 students of the whole campus probably share in my sophomore year.（介绍自己的科研经历，概述）isolating and identifying Monascus from the lees of Maotai distillery and studying Monascus’ enzymatic property, then making Monascus fortified Daqu(yeast for making hard liquor)

（表达对科研的兴趣爱好）Excited by the idea of becoming a scientist since I was a small child, my interests in pursuing graduate studies intensified during my undergraduate education and my research experience.Rather than discouraging me with the tremendous amount of the most important thing in life is to have a great aim and the determination to realize it!

work and demands for creativity, my college years motivated me to earn a master degree and to continue pursuing a career as a research scientist.（表达为什么选择了该校的某某专业）I am very attracted to the Graduate Program in FOOD QUALITY AND SAFETY at Jinan University, the program would suit me well cause I like to engage on the research about microorganism.My motivation to succeed is reflected in both my academic standing and my dedication to research.I feel that these attributes, combined with a profound interest in the microorganism, will ensure me success as a graduate student at Jinan University./(结尾备选)I really appreciate it if you could consider my application.If I could have the honor to study here, I promise that I could never fail your expectation.I’ll try my best to study and learn as much as I could to make contributions to the society and our country.So much, thank you for your attention./That's all.Thank you very much for your time and attention.几点说明：1.模板使用的是书面语言，口语化程度很小，面试的时候可以根据情况适当加入um，er，oh，well，so等口语词汇，同时做到做好断句，读的时候尽量不要让老师感觉到你是在背，注重语调上的变化。

2.模板里面填充自己相关信息，衡量自己说的关于奖学金和成绩荣誉方面的词汇对方能否听清，分清主次，和盘托出不是好办法，the most important thing in life is to have a great aim and the determination to realize it!

说出最重要的一两个奖项，然后其它内容一句概括。

3.关于自己在科研方面的成绩和体会要重点说。

4.时间有限，可能面试现场你能说的英语就那么几句，所以尽量缩短演讲稿。可能会出现老师中途打断，感觉英语太罗嗦的话。所以要精。

Wish ya good luck!
