Samples from a ceramic vase found at a tomb in Sicily prove that the vase was manufactured in Greece. Since the occupant of the tomb died during the reign of a Sicilian ruler who lived 2,700 years ago, the location of the vase indicates that there was trade between Sicily and Greece 2,700 years ago.

Which of the following is an assumption on which the argument depends?

       (A) Sicilian potters who lived during the reign of the ruler did not produce work of the same level of quality as did Greek potters.

       (B) Sicilian clay that was used in the manufacture of pottery during the ruler’s reign bore little resemblance to Greek clay used to manufacture pottery at that time.

       (C) At the time that the occupant of the tomb was alive, there were ships capable of transporting large quantities of manufactured goods between Sicily and Greece.

       (D) The vase that was found at the Sicilian tomb was not placed there many generations later by descendants of the occupant of the tomb.（D）

       (E) The occupant of the tomb was not a member of the royal family to which the Sicilian ruler belonged.

答案是

小弟愚昧!请各位NN指点?

Since the occupant of the tomb died during the reign of a Sicilian ruler who lived 2,700 years ago, the location of the vase indicates that there was trade between Sicily and Greece 2,700 years ago.

这两句话怎么就有因果关系了(由于墓主死于2700年前SICILIAN的统治时代,这陶瓷花瓶就意味着2700年前两个国家有贸易往来)

谢过先!

不好意思啦还有一道麻烦各位!XDF补充教材上的,大全里没有!

In Patton City,days are categorized as having heavy rainfall(more than two inches),moderate rainfall(more than one inch, but no more than two inches),light rainfall(at least a trace,but no more than one inch),or no rainfall.In 1990,there were fewer days with light rainfall than in 1910 and fewer with moderate rainfall ,yet total rainfall for the year was 20 percent higher in1990 than in 1910.

If true above,then it is also possible that in Patton City

A the number of days with heavy rainfall was lower in1990 and in 1910

B the number of days with some rainfall,but no more than two inches, was the same in 1990 as in 1910

C the number of days with some rainfall, but nore thatn two inches, was higher in 1990 than in 1910

D the total number of inches of rain that fell on days with moderate rainfall in 1990 was more thanb twice what it had been in 1910

E the average amount of rainfall per month was lower in 1990 than in 1910

答案是:A

难道是规律推导的年下雨天少吗?

那TOTAL RAINFALL还比1910年高,我倒觉得D好像对.请NN指点!

any NN,help me!thank you 啦!

唉!都几天了,都没人理我

1. 在sicily一个古墓发现的陶瓷花瓶被证明是在希腊生产的。sicilian统治者生活在2700年前，由于古墓的主人在sicilian统治时期死的，则发现该花瓶的地点表明在2700年前sicily和希腊存在贸易往来。

试想：除了贸易往来外，有没有其他可能原因使在希腊生产的花瓶出现在sicily？比如说后来有人放进去的？如果否定了他因，那么便能确定确实有贸易往来。

谢谢了lismiles!唉:一时大脑断路了,不好意思!

还请各位帮我解答下2楼的题,大全上没有.谢先

感觉是道数学题.看总量与组成部分的关系.但A是不是写错了?

A the number of days with heavy rainfall was lower in1990 and in 1910

felix_zheng

对对不好意思是LOWER   THAN.

但是还是没明白,

THERE were fewer days with light rainfall than in 1910 and fewer with moderate rainfall ,yet total rainfall for the year was 20 percent higher in1990 than in 1910.

1990年下小雨和中雨的天数均比1910年少,且各自全年总降雨量1990高于1910===20/%

而且各种类型雨量都有定量标准,也就说天数越少,该种类型的雨量也少.

那唯一可以拉高全年降雨量就应该靠大雨降雨量,这东西怎么会反而天数少呢????????????????

欢迎各位指点!

答案A，无悬念！

题目条件给的是M1-2和L 0-1 在1990年小于1910年的天数，注意是天数，而不是总量。

但是同时要注意H是大于2的，这样就出现一种情况：1990年一天的大雨的降雨量远大于1910年的一天的降雨量，虽然总天数不如1910年多！！！！

D错在于M1-2的总降雨量在1990年是1910年的两倍，这是不可能的。因为它不像H>2它无上限限制范围，而M上限是有范围的，条件是1990年M的天数小于1910年的天数。现在就假设1910年M是1，而1990是2，因为条件总降雨量=天数*平均每天的降雨量。后者的已经将其最大数值代入，但无奈，还是小于1910年的两倍。故D错。
