2011年诺贝尔化学奖授予了准晶体的发现者--以色列科学家谢西曼,他于1982年首次在实验室中合成出了准晶体。正常的晶体中,原子或分子的排列形式是立方体、六边形或其他规则的、可无缝拼合的模式。而准晶体的结构很特殊,小范围内看不出规则模式,但大范围可以体现出规则的,可拼合的模式。由金属原子组成的准晶体有固定的熔点,但导电导热能力却很差,容易像非晶体的玻璃那样破裂。

  自然界中形成的准晶体是在2008年发现的,在一块来自俄罗斯东部的奇怪岩石内,意大利科学家发现了一种已知的准晶体类型——AL63CU24FE13。更惊人的事情还在后面,最近意大利和美国科学家对这块岩石进行了同位素测定,发现岩石里的氧同位素的特征与某些碳质陨石类似,换句话说,这块岩石可能来自地球之外!该陨石很可能是45亿年前太阳系早期动荡环境的产物。

  含有准晶体的陨石是如何形成的?这依然是个谜,太阳系中绝大部分陨石都是小行星带中没有形成大天体的物质,但这块陨石中的铝的形式很古怪,不可能是在小行星带的环境中产生的,在其他的陨石中也没有发现这种铝的形式,既然陨石来自地球之外,那么这种含有准晶体的陨石的起源一定不寻常。研究人员猜测,也许这块陨石所在的前身星球上曾经发生过高速的撞击事件,在极端的环境中产生了这种陨石。

  这块陨石告诉我们,罕见的准晶体其实可以在自然界中产生,并且在几十亿年中保持稳定。

In Victorian times, certain flowers expressed meanings because the flower selection was limited. Therefore, flower as a gift was an effective tool in social communication. With so many choices today, we have no rules in flower choosing. However, people tend to give a certain flower their own personal meaning--- maybe it can remind them of some particular friends or events. Here I would introduce the traditional meanings of some gift flowers as a reference for your flower choosing.

Carnation(康乃馨) is a good gift for your female teacher or mother, but not all kinds of carnations mean respect and love. Different colours have different meanings. Generally, carnation means “fascination and woman love”. Specifically, pink carnation means “I’ll never forget you” and red carnation says “I admire you”. But some carnations have very negative meanings. If you want to say goodbye to your girlfriend, you can send her a bunch of striped carnations or yellow ones, because it means “Sorry I can’t be with you. You disappointed me.”

Rose is no doubt the best gift for girls in love. Basically, it relates to the love between men and women, but roses with different colours stand for different stages of love. Red rose is man’s best friend when he wants to show his love to a girl. In the peak of his love, pink rose is more suitable because it means “perfect happiness and please believe me”. While the love gets into trouble, yellow rose seems to be the best symbol. It means “the decrease of love and jealousy”.

Though you are free to choose any kind of flower as long as it is beautiful, I think this brief introduction can help you avoid making mistakes. Besides, the receivers must be happier if he or she gets to know the good will you convey in flowers.

1. Why do we choose certain flowers as gifts?

A. Because they are the best gifts for you. 

B. Because flowers all look beautiful

C. Because different flowers smell good.  

D. Because they can express specific meanings.

2. In different stages of love, ________.

A. roses of different colours show love to a girl.

B. you can choose red rose at any occasion

C. yellow rose is the best symbol for your love

D. pink rose implies that your love comes to maturity(成熟).

3. What does the passage mainly talk about?

A. Carnation is better than rose            B. Like the carnation, like the rose

C. Different flowers have different meanings  D. Flowers of different colours
