的确，我们想象不了出现在三维空间背景上的四维物体是什么样子。正如同我们不可能将一个三维物体压进一个平面那样。当然我们确实可以在二维的平面上画出三堆的物体来。因而从某种意义上来说，是将一个三雏物体压进了一个平面，然而，这种压法是用几何投影的方法进行的。同样，我们可以说，尽管不能把一个四维物体压进三雏空间．但我们能够讨论四雏物体在三维空间的投影。不过要记住，四维物体在三堆空间的投影是立体图形。正像三维物体在平面上的投影是二维图形一样。
但是。只要再思考一下，你就会意识到．把第四个方向看得太神秘是毫无必要的。事实上．有一个我们几乎每天要用的字眼可以用来表示．并且也的确就是物理世界的第四个独立的方向，这个字眼就是时间，所有的实际物体都是四维的：三维属于空间，一维属于时间。从这个新观念出发，一个四雏正方体就是一个存在了一段时间的三堆立方体。
1选出说法不正确的一项 (
A．文中的“维”是指方向。
B．文中的“二维”是指高(长、宽．即平面是二维的。
C．文中的“三维”是指高(长、宽、厚，即立体是三维的。
D．根据B、C提供的条件．我们可以知道“点”是“一维”的。
2第一段的意思是 (
A．四维空间很神秘的说法是错误的。
B．人类尚不具备探讨四维空间的条件。
C．人类的三维头脑不能想象出四维的情景。
D．人类的思维障碍造成了四维空间的神秘化。
3“看得太神秘”是指 (
A．宇宙中还有未被发现的第四维。
B．宇宙中是否有第四维存在是不可知的。
C．作为第三维空间中的人无法认识第四维。
D．“第四维”概念的提出与人们的传统观念不相符。
4下列说法与文意吻合的一项是 (
A．我们所处的.是一个三维空间，这一空间之外还有一个未被认识的四维空间存在。
B．我们所处的空间本身就是一个四维空间，我们所知的三维体实际上都是四维体。
C．所谓四维空间是一种理论上的假说，实际上是不存在的。
D．由于人们暂时还未发现第四维，便用“时间”来代替第四维。
参考答案：
1.D（本题考查对文中的信息进行筛选和辨析的能力。A此说法的搜选区间在第三段“第四个独立的方向”处；B此说法的搜选区间在第一、二段；C项的搜选区间在第二段；D项“点”不是一维的．应是二维的。）…点此进入高中说明文阅读训练参考答案100则查看完整参考答案（本文答案在第3页）…4.B（A项第四段说“一个四维正方体就是一个存在了一段时间的三维立方体”．可见，对四维的概念，人们是有认识的；另外“所有的实际物体都是四维的”，也证明此项错。B项内容可从第三段中找到。由B项可证明C错。D项原文说时间“的确就是物理世界的第四个方向”，即第四维。）

The Lord and the Hermit
Once upon a time there was a rapacious lord. He was relentless to his tenants and quelled them by placing quotas to their living condition. Soon he collected quantitatively great revenue and lived in a radiate palace. He was also renowned for his queer clothes.
One day the lord’s disease relapsed, so he rallied his subordinates for help. One of them said: “I’ve heard of a recluse who knows regimen well residing nearby. Why not visit his residence for help?” Another retorted: “Be prudent, maybe it is only a rumor.” But the rash lord was filled with rapture and ratified the visiting plan.??
On the next Sunday, the lord purged himself, held a quaint rite and started for the hermit’s home. They passed rugged rustic passages full of paddles and the lord almost recoiled. Finally they arrived. The lord felt disappointed at the recluse’s reception, but he wouldn’t relinquish the chance and talked to the hermit with reverence.
The hermit ruminated and reverted to the main topic in a pungent voice: “I’ve heard lots of your ravenous deeds. You retract the land you’ve distributed to the farmers and order them to redeem their land. You must redress your guilt and rehabilitate their freedom. Reimburse their respective debts and build refuge for them. You can retain the residue of your property.”??
The lord was reluctant to renounce his wealth and be rent from his palace. He rebuked: “Your advice is too reckless. I’m resolute not to accept it.”
“Why so repulsive? You cannot repudiate my words.” The hermit reiterated his suggestion and its resonance echoed. “Remit their taxes with rebates, or a riot is imminent.”
The lord again refuted. At last he went back in remorse.

Prisoners of War?
Thousands of war prisoners were kept in captivity in the bulky camp. They lived in clutter and had to deal with chore. They must show categorical obedience or else receive caustic chiding. The guarding officers censure them very often, as well as clamoring carnal punishments. Some captives got bruise and clots all over. Male prisoners lost their collaterals and female ones fail to keep chaste.??
They wear burnished canvas, and rested in circumscribed room with small capacity and caliber. They chafe each other and brawled frequently. They were chary of moving and can hardly budge. Their situations captivated lots of reporters, who castigated the government with cogent proof. However, the government gave bombastic data and bragged about the conditions in the camps.??
After the calamity of war ceased, large numbers of captives were longing for the boon of brisk free life. According to a clandestine bond between the two canny governments, a process of exchanging captives will soon commence. This is considered as opening a cleft in the clogged wall between the two countries.

按图表写，首先要读懂图表，理解其包含的信息。为此目的，应注意三点：第一是读懂标题，明白图表的目的；第二是研究图表主题，理解各项内容及其之间的联系；第三是注意图表的说明或图例，以免误解。总之，对图表的研究要仔细,理解和判断要准确，不能草率做出决定，以免在文章内容方面丢分。
读懂图表之后，立即思考文章应表达的内容。这里,我们应该明白两个制约因素：其一是作文写作时间只有二十多分钟，不可能长篇大论；其二是图表内容繁多，不可能一一说明，也不能写成枯燥无味的'流水账。考虑取舍时,应注意总的趋势，概貌，相互关系，典型的例子或数据，抓住这些之后，其他的内容实际上也包含在其中，不必再提及。
文章的写法没有固定的模式，但因题材的限制，变化太大也不可能。第一段必须说明图表的性质与目的，没有这一点，文章的主题难以突出。自然段的划分以清楚明了为原则，例如第一段谈图表的目的，其余自然段应当以所谈要点划分，最后一段可谈自己的理解和看法(也可不谈。写作时的关键是每个要点谈完后,应给出例证，把该说地说完,然后再进入下一要点，不能不顾文章条理,把想到的内容随便乱放。
再语言方式上，要注意句式的变化，尽量避免反复使用某一句型。再并列情况较多时，设法采用连结词或关系词将领岁的内容串在一起，为文章的主题服务。全文的思路可以用主题句，自然段,逻辑词等手法表明，使读者感到作者的思路清晰，感到全文是个有机的整体。遇到众多雷同的词汇短语时，能变化的尽量变化，无力变化时可用句式变化弥补。
