Communication
The world we are living in is amazing(令人吃惊的). There are countless living things. How can they live harmoniously(调和地)? The answer is communication.
Communication, of course, doesn’t need to be in words. We can talk to each other by a smile, a frown(皱眉), a shrug(耸肩) of our shoulders, and a gesture(手势) with our hands. Shaking hands is a very common gesture, which is performed both on initial(开始的, 最初的) greeting and departure(出发). We know that birds and animals use a whole vocabulary(词汇) of songs, sounds, and movements. Bees dance their signals, flying in certain pattern(模式) that tell other bees where to find nectar(【植】花蜜) of honey(甘美的).
Can plants talks? Yes---but not in words. We have reasons to believe that trees do communicate with each other. Not long ago, researcher learned some surprising things. First, a willow(柳树) tree attacked in the woods by caterpillars(毛虫) changes the chemistry of its leaves and made them taste so awful that the caterpillars go disgusted(厌烦地) and stopped eating them. Then, ever more astonishing(令人惊讶的), the tree sent out special vapors(水汽)---an alarm signal stimulating(刺激) its neighbors to change the chemistry of their own leaves and make them less tasty(【口】美味的)
Communication is so important in the nature world. As human beings we should communicate with each other to make the earth peaceful.

How to Be Successful in a Job Interview
To be successful in a job interview or in almost any interview aituation, the applicant should demonstrate certain personal and professional qualities.
Most likely, the first and often a lasting impression of a personis determined by the clothes he wears. The job applicant should take care to appear well-groomed and modestly dressed, avoiding the extremes of too pompous or too casual attire.
Besides care for personal appearance, he should pay close attention to his manner of speaking, which should be neither ostentatious nor familiar but rather straightforward, grammatically accurate, and in a friendly way.
In addition, he should be prepared to talk knowledgeably about the requirements of the position, for which he is applying in relation to his own professional experience and interests.
And finally, the really impressive applicant must convey a sense of self-confidence and enthusiasm for work, as these are factors all interviewers value highly.
If the job seeker displays the above-mentioned characteristics, he, with a little luck, will certainly succeed in the typical personnel interview.

On Friendship
Everyone needs friendship. No one can sail the ocean of life single handed. We need help from, and also give help to, others. In the modern age, people attach more importance to relations and connections. A man of charisma has many friends. His power lies in his ability to give.
The term, friend, covers a wide range of raeanings. It can be a nodding acquaintance, a comrade, a confident, a partner, a playmate, a brother, an intimate etc.
As life is full of strife and conflict, we need friends to support and help as out of difficulties. Our frinods give us warnings against danger. True friends share not only joy but, more often than not, they share sorrow.
With friendship, life is happy and harmonious. Without friendship, life is hostile and unfortunate. I have friends in the rank and file. Some are rich and in power. Some are low and common. Some are like myself, working as a teacher, reading and writing and content with the simple life we have. To many of my friends, I know what to treasure, what to tolerate and what to share, I will never forget my old friends and keep making new friends. I will not he cold and indifferent to the poor friends and will show concern for them, even if it is only a comforting word.
谈友谊
人人都需要友谊，没有人能独自在人生的海洋中航行。我们给人帮助也需要别人的帮助。在现代，人们更重视关系和联系。一个有领袖气质的人有许多朋友，他的权力在于他的给予能力。
朋友的意义很广，可以是熟人、同志、知已、伙伴、玩伴、兄弟、密友等。
生活充满矛盾和斗争，我们需要朋友的支持，以帮助我们摆脱困境。朋友提醒我们警惕险难。真正的朋友不仅与我们同甘，而且共苦。
友谊使生活幸福，和谐，没有友谊的生活充满敌意和不幸。我有地位高的朋友，也有地位低的朋友，有的有钱有权，有的位卑而平凡。有的和我一样教书，读写，满足于简朴的生活。对我的众多朋友，我知道该珍惜什么，容忍什么，分享什么。我不会忘记老朋友，同时继续交新朋友。对穷朋友不冷漠，关心他们，哪怕只是一句安慰的话。

Where There Is a Will There Is a Way
1．坚强的意志是成功的重要保证。
2．意志坚定的人才能完成伟大的使命，
3．学生也是这样，不刻苦学习，终究不会成为有用之才。
One of the most important things to succcss is a firm.reso1ution. A great man is al ways one who has a firm resolution and an inflexible spirit. One will never succeed all his life without a firm will to get the final victory.
As a rule, great tasks are accomplished by men of strong will. For example, Dr. Sun Yatsen set the Cbinese people free from the rule of the Qing Dynasty through a long pcriod of hard struggle. Many of his attempts failed and many of bis followers were killed, but he had an inflexible spirit and sticked to his cause. Finally, he made the revo lution of 1911 a success.
A student who has no resolution will never succeed in his studies. The same is true of men in all walks of life. We must have a firm resolution first, if we wish to succeed. We must always remember thc old saying that where there is a will there is a way.
有志者事竟成
坚强的意志是成功的重要保证。伟大的人物总是有坚强的决心和不屈不挠的精神。一个人没有争取胜利的坚定决心，决不会成功。
一般地说，意志坚定的人才能完成伟大使命，譬如，孙中山先生经历了长期的艰苦斗争把中国人民从清朝统治下解放出来。他的许多次尝试失败了，他的许多追随者遭到杀害。然而，他取得了1911年革命的成功。
没有坚强意志的学生在学习上不会成功。在生活的各个方面也是如此。如果我们想要成功，首先要有坚强的意志。我们应当牢记这句俗话：有志者事竟成。

腊叶标本就是经过压榨和干燥处理的植物标本，也叫压制标本。只有经过这样处理的标本，才能长久保存而不致霉烂。其制作过程如下：
1)压榨干燥。将采来并经过修整后的标本，铺垫好吸水性强的纸数张，矫正好标本花和叶的位置。摆放标本时，应注意显示植物的自然状态，避免花、叶压在一起，互相重叠。应该使标本有一个或几个花、叶转过来，以观察它们的背面。然后把它们用压榨板或标本夹压好，并用绳子捆绑紧。
换纸必须勤快，刚采回的新鲜标本，头3天要每天换纸3～4次，至少换2次，以后可每日换1次。换下来的湿纸晒干，以便再次使用。干燥需要时间长短，以植物本身性质而定，一般植物的干燥处理约需要4～5天。鉴别标本干燥得是否适度的简单方法是，当我们拿起标本时，如果是没有干的标本，个别柔软的部分，容易弯曲下垂；过于干燥的标本，很容易弯曲折断；干燥适度的标本有弹性，且不易破损。
2)消毒处理。因为植物体上往往有虫子或卵在其内部，如不消毒，则会被虫子蛀食破坏。
消毒方法可以将压干的标本放在消毒室或消毒箱内，再放敌敌畏于玻璃器皿内，置入室内或箱内，利用气熏法杀虫。约3天后取出即可装帧。
3)上台纸、贴标签。把已经干燥的标本放在台纸上，摆好位置，尽量作到美观，尤其应注意标本的花枝不可太近台纸边缘，否则易碰坏。固定的方法有多种。可用线将标本牢固地缝在台纸上；也可以用纸条贴在台纸上，或在台纸上要固定植物枝条的地方。用刀各割一个小口(宽窄正好能穿过纸条)，穿过纸条，把纸条的两端粘贴在台纸的背面。
每件腊叶标本必须附有标签。标签是标本的科学证明，标签要按野外记录逐项填写清楚。通常贴在台纸的右下角。
4)贴标本衬纸。最后，将一张跟台纸同样大小的油光纸贴在台纸上端的边缘，使油光纸盖在标本上面，以保护标本。

如何制作植物标本
目的要求：初步掌握制作腊叶标本的方法。
材料用具： 采集来的植物，旧报纸或草纸，刷子或纱布，标本夹或两块比台纸大一些的木板和书，吸水纸或棉絮，台纸，标签，胶水，胶带或缝衣针和线，毛笔，刀片，剪刀，玻璃纸。
制作方法 ：
从采集来的同一种植物中选择各个器官最完备的做标本。用刷子或纱布擦掉标本上的污物，保持标本清洁美观。把整理好的标本夹在干燥的旧报纸或草纸中，用标本夹压起来，或者放在两块木板中间，上面用书或砖头压紧。在压的时候，应该注意标本是否平整，叶和花的位置是否自然，避免互相遮盖。如果标本过长过大或者枝叶过密，应该加以适当修剪或弯折。如有硬刺，要先压平。有些植物的叶片背腹面是有显著区别的，要把一部分叶片翻过来。
压标本的地方要通风、有阳光，否则标本就不容易干燥，而且会卷曲、变黑，失去原有的绿色。花的上面必须放吸水纸或棉絮。每天要用干纸替换湿纸，湿纸晒干或烘干以后还可以用。在换纸的时候要注意摆正植物的姿态。也可以把植物夹在吸水纸里，用熨斗熨平。
植物压干以后，就用线或胶带选几个点固定在台纸上。小的植物或枝叶柔软的标本，可以用毛笔蘸胶水涂在标本的一面，粘贴在台纸上，略微用力按一按，搁置半天到一天，等它阴干后再用胶带把胶水
没有粘牢的部分在台纸上固定起来。如果用针叶树的枝条做标本，最好先把它浸泡在开水里，或者放在稀薄的胶水中蘸一下，然后压平，这样可以防止针叶散落。
腊叶标本制作完毕以后，要在台纸的右下角贴上标签，注明编号、
科名、学名、中名、俗名、产地、采集日期、采集者。
