下列有关文学常识的表述，不正确的一项是[ ]

A．词又称“曲子词”“长短句”“诗余”等，是盛行于宋代的一种文学体裁，但在唐、五代时就已经出现。温庭筠、韦庄是唐代词人的杰出代表，在他们的影响下出现的《花间集》是我国最早的一部词集。     

B．南唐后主李煜是词史上第一流的大家，他早期的词多写男女的悲欢离合，题材狭窄，风格柔丽；后期的作品主要写亡国之恨，拓展了词的创作内容。     

C．苏轼是宋代最伟大的词人之一，他的词作体现了开阔的胸襟，包含了深沉的人生况味。苏轼极大地开拓了词的题材、意境，被视为豪放派的创始人，后人将他与南宋豪放派词人辛弃疾合称为“苏辛”。     

D．李清照，号易安居士，是宋代婉约派词人的杰出代表，也是中国文学史上最杰出的女作家之一。陆游是中国历史上一位著名的多产诗人，其诗风雄浑，而词风哀婉，因此他与李清照一起被视为宋代婉约词派的代表。

What is colour? Why do some of the things around us look red, some green, others blue?

　Colours are really made by reflected(反射)light. We see colour because most of the things reflect light. Something is red, for it reflects most of the red light. In the same way, if something is green, it reflects most of the green light. If something reflects all light, it is white. If it doesn‘t reflect any light, it is black.

　Some of the light is reflected and some is taken in(吸收)and turned into(变成)heat(热能).The darker the colour is, the less light is reflected, the more light is taken in. So dark-coloured(深色的)clothes are warmer in the sun than light-coloured clothes.
