When 18th-century scientists first came across Australia’s platypus(鸭嘴兽), they thought it was a trick. It is not surprising that the platypus made people confused. This funny-looking animal has feet and is a kind of warm-blooded mammal.
While other mammals usually keep their blood at around 37 degrees, the platypus has a lower body temperature of 32 degrees. As to its appearance, the platypus’mouth is not really like ducks’at all; its mouth actually looks a bit soft. The platypus closes its eyes when swimming. It uses its mouth to pick up outside information made by the creatures underwater.
Strangest of all, the platypus is a mammal that can lay eggs. And there is only one other kind of mammal that can lay eggs, the echidna (针鼹鼠) of Australia. Both the platy-pus and the echidna lay soft-shelled eggs, and both feed their young with their own milk that comes out of their skin. These animals also walk in a way that is similar to crocodiles(鳄鱼), with legs on the sides of their bodies rather than under them.
Though pretty, in a special way, the platypus is actually one of the few mammals that are poisonous. A male platypus has knife-like bones on its back legs which have enough poison to kill a dog.
The platypus has the honor of being one of the oldest mammals in the world. Until the early 20th century, it was hunted for its fur, but the situation has changed. Although the platypus is easily affected by pollution, it is not under any immediate threat. What can we learn about the platypus according to the text?
| A．It has a lower body temperature than other mammals. |

A plane crash in Western Russian killed Polish President Lech Kaczynski and the other 96 political and military officials on board on April 10. The accident has led to huge national mourning in Poland. But it may provide an opportunity for reconciliation (和解) between Poland and Russia, countries that have a troubled relationship.
Many from the political elite were lost in the crash. Beside the president, the dead include the army chief of Staff, the head of National Security Bureau, the national bank president, the deputy foreign minister and other members of parliament.
The Polish delegation was heading to Russia to mark the 70 th anniversary of the Katyn Massacre (屠杀) when the accident occurred. In 1940, about 22,000 Polish soldiers, intellectuals, and officials captured after the Soviet Army invaded Poland in 1939, were killed secretly by Soviet police in the forest of Russia’s Katyn.
The Katyn Massacre had been a sensitive topic between the countries. The former Soviet Union always denied responsibility for the massacre. It was not until 1992 that Russian released archived documents about the killing.
Katyn is merely a short chapter in Poland and Russia’s long and troubled history. In the 18 th century, along with Prussia, (then an important part of Germany) and Austria. Russia participated in three carve – ups of Poland. In 1795, after the third carve – up, the country was erased from the map of Europe. It was in 1918 that Poland regained its independence. But in 1939, at the beginning of the World War II, it was invaded by Germany and the Soviet Union under a secret pact. After the war, Poland became a communist country with close ties to the Soviet Union.
In 1989, Poland switched to capitalism and pursued a pro – West position. The most recent tension between the two countries was in 2008. That year, Poland decided to have a US missile shield (导弹防御系统) on its soil, while neighboring Russia threatened to aim missiles at Poland.
But the plane crash has created a chance for reconciliation, with Russia sharing the sadness of Poland. Russia has declared April 12 a day of mourning for the victims. Flags flew at half – mast in Moscow. And earlier on April 7, Russia Prime Minister Vladimir Putin became the first Russian leader to mark the anniversary of the massacre.
“I think it should improve relations between the two countries, as Russians feel our grief,” said Radek Sikorski, Pland’s foreign minister.
66．Put the following events in order of time.

In a surprising discovery about where higher life can survive, scientists have found a shrimp -like creature and a jellyfish swimming beneath an Antarctic ice sheet.
About 180 meters below the ice where no light can get through, scientists had figured nothing much more than a few microbes (微生物) could exist.
That’s why a NASA team was surprised when they lowered a video camera to get the first long look at the underbelly of an ice sheet in Antarctica. A curious shrimp – like creature came swimming by and then parked itself on the camera’s cable. Scientists also pulled up a tentacle (触须) they believe came from a jellyfish.
“We were operating on the presumption that nothing’s there.” Said NASA ice scientist Robert Bindschadler. “It was a shrimp you’d enjoy having on your plate.”
“We were just gaga (狂热的) over it,” he said of the 7.5cm long, orange creature starring in their two – minute video. Technically, it’s not a shrimp. It’s a Lyssianasid amphipod, which is distantly related to the shrimp.
The video is likely to inspire experts to rethink what they know about life in harsh environments. And it has scientists thinking that if shrimp – like creatures can live below 180 meters of Antarctic ice in freezing dark water, what about other cold places? What about Europa, a frozen moon of Jupiter?
Cynan Ellis – Evans, a scientist of the British Antarctic Survey called the finding fascinating. He said it was possible the creatures swam in from far away and don’t live there permanently.
But Kim, who is a co-author of the study, doubts it. “The site in West Antarctica is at least 19 km from open seas. Bindschadler drilled a 20 cm – wide hole and was looking at a tiny amount of water. That means it’s unlikely that two creatures swam from great distances and were captured randomly in that small of an area,” she said.
Yet scientist were puzzled at what the food source would be for these creatures. While some microbes can make their own food out of chemicals in the ocean, complex life like the shrimp can’t, Kim said.
“So how do they survive? That’s the key question.” Kim Sai.
“It’s pretty amazing when you find a huge puzzle like that on a planet where we thought we know everything.” Kim said.
61．Scientists had believed that harsh environments could only have been populated by .
A．jellyfish B．mammals C．microbes D．shrimp – like creatures
62．According to Kim, the shrimp – like creature .
A．swam great distances to Antarctic B．has always lived in the region
C．gradually evolved from shrimps D．has nothing in common with shrimps
63．The finding is significant in that .
A．it marks NASA’S first Antarctic biological study
B．it proves there is marine life in the Antarctic
C．it could inspire further study of life in harsh environments
D．it shows that Lyssianasid amphipod is closely related to shrimps
64．The last three paragraphs suggest that .
A．researchers will look at the places the creatures came from
B．ice scientists will drill deeper to find more creatures
C．scientists know very little about the planet they live on
D． further research will be done about what the creatures live on
65．Which of the following statements about the discovery is FALSE?
A．Complex life usually lives on other forms of life.
B．Scientists saw two creatures in the two – minute video.
C．It is possible for creatures to live 180 meters below the ice though there is no light.
D．Scientists captured the shrimp – like creature in a camera by drilling a hole through the ice.
PART THREE READING COMPREHENSION（30 points）
Directions: Read the following three passages．Each passage is followed by several questions or unfinished statements．For each of them there are 4 choices marked A,B,C and D．Choose the one that fits best according to the information given in the passage．
Next time you find yourself drenched (湿透) in an unexpected heavy rain, look on the bright side – it will be a memorable experience. While wet weather may make us feel gloomy, it sharpens the memory and improves our recall. But those who feel in a good mood because it’s a sunny day are able to remember less well, according to memory tests carried by Australian researchers.
Professor Joe Forgas, who led the research, said: “It seems strange but a little bit of sadness is a good thing. People performed much better on our memory test when the weather was unpleasant and they wee in a slightly negative mood. On bright sunny days, when they were more likely to be happy, the flunked it.”
The tests were carried out on shoppers at a store in Sydney, where researchers randomly placed ten small objects on the check – out counter. On rainy days, sad music was played in the store. When it was bright and sunny, customers heard cheery music. This was done to further influence them towards negative or positive moods. After shopping, customers were asked how many of the objects they could remember. Their scores were three times higher when the weather was had and they were feeling angry, compared with those tested on sunny days. The results were published in Journal of Experimental Psychology. A report on the findings said: “They point to a growing body of evidence that the way people think, the quality of their judgments and the accuracy of their memory are all significantly influenced by positive and negative moods.”
Professor Forgas said, “We found that weather – inducted negative mood improved memory accuracy. Shoppers in a negative mood showed better memory and higher discrimination ability.”
A worse mood helped to focus people’s attention on their surroundings and led to a more thorough and careful thinking style, while happiness increased confidence and forgetfulness.
Being happy tends to promote a thinking style that is less focused on our surroundings. In a positive mood we are less likely to make more snap (匆忙的) judgments about people we meet. Mild negative mood, in turn, tends to increase attention to our surroundings and produce a more careful, thorough thinking style.
Accurately remembering everyday scenes is a difficult task, yet such memories can be on importance in everyday life. Surprisingly, the influence of mood states on the accuracy of real-life memories is still poorly understood.
56．What’s the major function of Paragraph 1?
A．To attract readers’ interest.
B．To introduce the theme of the whole passage.
C．To generalize the whole passage.
D．To describe a memorable experience.
57．The underlined word “flunked” in Paragraph2 may mean “ ”.
A．conducted B．failed C．passed D．understood
58．In the research, researchers play different music to .
A．make customers become sadder or happier
B．help customers choose what they want
C．promote customers to buy more goods
D．get customers to make a quick choice
59．According to Joe Forgas, on sunny days, people .
A．will make careful judgments on others
B．tend to pay more attention to their surroundings
C．will have more confidence
D．will have a better recall
60．What can we know from the research?
A．Forgetfulness is rather troublesome.
B．It’s important to feel in a good mood.
C．It’s memorable to experience a rainy day.
D．Gloomy days are good for memorizing things.
What will man be like in the future-in 5000 or even 50,000 years from now? We can only make guesses, of course, but we can be sure that he will be different from what he is today. For man is slowly changing all the time.
Let us take an obvious example. Man, even five hundred years ago, was shorter than he is today. Now, on average, men are about three inches taller. Five hundred years is relatively short period of time, so we may suppose that man will continue to grow taller. Again, in the modern world we use our brains a great deal. Even so, we still make use of only about 20% of the brain's capacity. As time goes on, however, we shall have to use our brains more and more, and eventually we shall need larger ones! This is likely to bring about a physical change to the head, in particular the forehead, will grow larger.
Nowadays our eyes are in constant use. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over very long period of time it is likely that man's eyes will grow stronger.
On the other hand, we tend to make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they are used a great deal in modern life.
But what about hair? This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future, then, both sexes are likely to be bald.
Perhaps all this gives the impression that future man will not be a very attractive creature to look at! This may well be true. All the same, in spite of all these changes, future man will still have a lot in common with use. He will still be a human being, with thoughts and emotions similar to our own.
71. The passage mainly tells us that ________.
A. man's life will be different in the future
B. future man will look quite different from us
C. man is growing taller as time passes
D. man will disappear
72. What serves as the evidence（证据）that man is changing?
A. Man has got stronger eyes now than he ever had.
B. Man's hair is getting thinner and thinner.
C. Man's arms and legs have become lighter and weaker.
D. Man has been growing taller over the past 500 years.
73. The change in man's size of forehead is probably because ________.
A. he makes use only 20 % of the brain's capacity
B. his brain has grown larger over the past centuries
C. the other 80% of his brain will grow in due time
D. he will use his brain more and more as time goes on
74. What is true about a human being in the future?
A. He is hairless because hair is no longer useful.
B. He has smaller eyes and wears better glasses.
C. His fingers grow weaker because he doesn't have to make use of them.
D. He thinks and feels in different way.
75. We can infer that _______.
A. human beings will become less attractive in the future.
B. less use of a bodily organ may lead to its becoming worse
C. human beings hope for a change in the future life
D. future life is always predictable
