永远膨胀下去的宇宙的未来相当乏味。但是一点也不能肯定宇宙是否会永远膨胀。我们只有大约为使宇宙坍缩的需要密度十分之一的确定证据。然而，可能还有其他种类的暗物质，还未被我们探测到，它会使宇宙的平均密度达到或超过临界值。这种附加的暗物质必须位于星系或星系团之外。否则的话，我们就应觉察到了它对星系旋转或星系团中星系运动的效应。

为什么我们应该认为，也许存在足够的暗物质，使宇宙最终坍缩呢？为什么我们不能只相信我们已有确定证据的物质呢？其理由在于，哪怕宇宙现在只具有十分之一的临界密度，都需要不可思议地仔细选取初始的密度和膨胀率。如果在大爆炸后一秒钟宇宙的密度大了一万亿分之一，宇宙就会在十年后坍缩。另一方面，如果那时宇宙的密度小于同一个量，宇宙在大约十年后就变成基本上空无一物。

宇宙的初始密度为什么被这么仔细地选取呢？也许存在某种原因，使得宇宙必须刚好具有临界密度。看来可能存在两种解释。一种是所谓的人择原理，它可被重述如下：宇宙之所以是这种样子，是因为否则的话，我们就不会在这里观测它。其思想是，可能存在许多具有不同密度的不同宇宙。只有那些非常接近临界密度的能存活得足够久并包含足够形成恒星和行星的物质。只有在那些宇宙中才有智慧生物去诘问这样的问题：密度为什么这么接近于临界密度？如果这就是宇宙现在密度的解释，则没有理由去相信宇宙包含有比我们已探测到的更多物质。十分之一的临界密度对于星系和恒星的形成已经足够。

然而，许多人不喜欢人择原理，因为它似乎太倚重于我们自身的存在。这样就有人对为何密度应这么接近于临界值寻求另外可能的解释。这种探索导致极早期宇宙的暴涨理论。其思想是宇宙的尺度曾经不断地加倍过，正如在遭受极端通货膨胀的国家每隔几个月价格就加倍一样。然而，宇宙的暴涨更迅猛更极端得多：在一个微小的暴涨中尺度的至少一千亿亿亿倍的增加，会使宇宙这么接近于准确的临界密度，以至于现在仍然非常接近于临界密度。这样，如果暴涨理论是正确的，宇宙就应包含足够的暗物质，使得密度达到临界值。这意味着，宇宙最终可能会坍缩，但是这个时间不会比迄今已经膨胀过的一百五十亿年左右长太多。

【1】下列对宇宙“临界密度”的理解，不正确的一项是( )

A．宇宙密度的临界值很重要，大于它或者小于它最终都会导致宇宙膨胀而产生大爆炸。

B．为何宇宙必须刚好具有临界密度，人择原理和暴涨理论都是两种可能的解释。

C．如果宇宙的平均密度超过临界密度，那么宇宙就会坍缩。

D．如果宇宙的密度小于临界密度，它就不会坍缩而会永远膨胀下去。

【2】下列对“人择理论”的理解，正确的一项是( )

A．人择原理的提出是人们通过对宇宙的观测从而得出的理论。

B．人择理论者认为只有那些有智慧生物的宇宙，因为密度接近于临界密度，所以才得以“存活”。

C．人择原理实际上就是对宇宙密度的人为确定，因此宇宙密度也可以任意改变。

D．人择原理实际上就是从现行的宇宙状况出发去认识宇宙的临界密度，其思想即“存在就是合理的”。

【3】下列说法，不符合文意的一项是( )

A．暴涨理论反对人择理论那种对人们自身存在的过分倚重，而对宇宙的临界密度寻求另外可能的解释。

B．根据暴涨理论，宇宙的密度就是在一次次迅猛、极端的暴涨中接近于准确的临界密度。

C．如果暴涨理论是正确的，那么在星系和星系团之外可能存在着其他种类的暗物质。

D．现在的宇宙“安然无恙”既没膨胀也没坍缩，处于一种“稳定状态”。

【题目】 A clever cat has been called a hero after he prevented his owners’ home from burning down. Five-year-old Pepper has learned to open windows and lets himself out every night by using his paws to turn the latch. So when a fire broke out while his owners were at Christmas shopping, the quick-thinking cat leapt into action and opened the window to allow the poisonous smoke to escape.

Owner Sharon White said, “He can climb back in through the window, so he really does come and go as he pleases. Pepper is still a bit afraid but is still managing to eat plenty of food.” Sharon and her husband Phil were handed Pepper over four years ago after a neighbor could no longer look after it.

The fire started at 4 pm on Saturday after the couple went to the shops and left their microwave on a ten minute timer, which then caught fire. Sharon said, “We put something in the microwave for ten minutes and then went out to do our Christmas shopping in the local town. I discovered on the way that I had left my purse at home but decided not to turn around. It was my relative who lives next door that rang us and told us that we’d better get home as there was quite a lot of smoke coming out of our house and the firefighters were here.”

Firefighters rushed to their 350,000 house and put out the fire before it could spread and the kitchen suffered only smoke damage. Phil added, “Pepper managed to get out and smoke must have been pouring out the window which attracted the attention of the neighbors. He’s got a real mind of his own. Without him, the fire could have been so much worse.”

【1】 What is this passage mainly about?

A. A quick-thinking cat thanked his owners.

B. A quick-thinking cat saved a house from a fire.

C. A quick-thinking cat saved himself from a fire.

D. A quick-thinking cat showed how clever he was.

【2】 How did Pepper help avoid the danger of the fire?

A. By ringing a neighbor’s bell.

B. By running into a neighbor’s room.

C. By standing in the way of some fire fighters.

D. By opening the window and letting out smoke.

【3】 From Paragraph 2 we know that Pepper ____.

A. didn’t belong to Sharon at first

B. was not frightened by the fire at all

C. has been taught to open the window

D. was found by its owners on the street

【4】 What can we learn from what Sharon said in Paragraph 3?

A. She and her husband were terribly frightened.

B. She and her husband didn’t call the firefighters.

C. It was that [LU2] relative who first noticed the smoke.

D. She and her husband knew there would be no damage.

【5】 We can infer that Sharon and her husband Phil ____.

A. are very careful

B. lived a very poor life

C. are very thankful to Pepper

D. didn’t like Pepper before the fire
