阅读理解。
&&&& As one of nature's top predators (捕食性动物), the tiger is not an animal, that we would ordinarily think
of as being a chicken.
&&&& However, one tiger, which lives in an English zoo, turned out to be more cowardly than hi憨鼎封刮莩钙凤水脯惊s keepers could
ever have imagined.
&&&& Tanvir, a two-year-old Bengal tiger, got stuck at the top of a new 5m-high activity tower in his enclosure,
after climbing it for the first time.
&&&& The branching tower had been designed to provide mental stimulation for Tanvir by testing his ingenuity, but after scaling the exercise structure in just a few seconds, he lost his nerve when it came to coming back down.
&&&& Tanvir went on to spend nearly two days at the top of the tower trying to pluck up the courage to attempt a descent.
&&&& A spokesperson for the zoo said chat Tanvir had taken half an hour to come down from a smaller structure
only l.5m high previously, and that the taller tower had clearly been too much for him.
&&&& "Every time he gets to the edge, he looks out, puts a paw over, and thinks, 'no, I'm not doing it!'" said
Samantha Cordrey.
&&&& In the end Tanvir's hunger got the better of his fear, and after almost 48 hours he made his way down in
order to eat.
&&&& It appears that Tanvir is none the worse for his experience, but it is not known if he will find the guts (勇 气) to go back up his exercise tower again.
&&&& The whole episode only serves to underline the difficulties faced by zoo staff in creating environments that
will stimulate the animals living in enclosed spaces.
&&&& "It was made to challenge him but he's a bit of a wimp," said Tanvir's keeper.
1. From the first paragraph we can learn that ____.
A. tigers are often compared with chickens
B. tigers have nothing to do with chickens C. tigers sometimes feed on chickens
D. tigers are generally not so cowardly
2. Which of the following is true?
A. It took Tranvir an hour and a half to come down from the tower.
B. The first tower did not have any effect in training the tiger.
C. It is uncertain whether Tanvir will go back up the tower once more.
D. Tanvir enjoyed his stay on the tower so much that he refused to come down.
3. What's the purpose of the passage?
A. To tell us how timid a tiger became in an English zoo. B. To call on us to protect tigers that are being kept in enclosed spaces. C. To emphasize the difficulties of creating suitable environments for enclosed animals.
D. To tell readers how to train wild animals, such as tigers.
4. What can be inferred from the passage?
A. In fact the tower structure was not difficult for Tanvir.
B. Zoo keepers knew the structure was a bit difficult for Tanvir. C. Tanvir was the only tiger that was trained by the zoo keepers.
D. All tigers needed training before they were set free from the zoo.

出门在外也不愁两块铁皮的密度相同,可以利用这一关系进行求解.测量的边长和厚度,以及的质量,利用公式可求铁皮的密度.测出的质量,就可求其面积.
解:测量出铁皮的边长,设其厚度为(因厚度太小可能无法测量准确),用天平测出其质量;求出铁皮的密度;再测得铁皮的质量,求出其体积,再求其面积.答:用天平测出铁皮的质量;用刻度尺测出铁皮的边长,设其厚度为,算出其体积,则铁皮的密度为;用天平测出铁皮的质量,根据得,.
此题是密度公式在生活中的实际运用,要求学生利用密度的性质,一步步探究得出正确方法.

1-2月天数为59、3-6月天数为122、7-10月天数为123、11-12月天数为61.年平均城镇单位从业人员人数=[&#189;(140.2+142.5)×59+&#189;(142.5+144.1)×122+&#189;(144.1+149.5)×123+&#189;(149.5+148.8)×61]÷365=145.14
加起来，取平均，即可
不对的，加起来取平均数是145.02，但是答案是145.15
时间点都不一样的，不会就是简单平均的}
