A new study warns that about thirty percent of the world's people may not have enough water by the year 2025.
A private American organization called Population Action International did the new study. It says more than three-hundred-thirty-five-million people lack enough water now. The people live in twentyeight countries. Most of the countries are in Africa or the Middle East.
PAI researcher Robert Engelman says by the year 2025, about three thousand million people may lack water. At least 18 more countries are expected to have severe water problems. The demand for water keeps increasing. Yet the amount of water on earth stays the same.
Mr Engelman says the population in the countries that lack water is growing faster than in other parts of the world. He says population growth in these countries will continue to increase.
The report says lack of water in the future may result in several problems. It may increase health problems. Lack of water often means drinking water is not safe. Mr Engelman says there are problems all over the world because some diseases, such as cholera, are carried in water. Lack of water may also result in more international conflicts. Countries may have to compete for water in the future. Some countries now get sixty percent of their fresh water from other countries. This is true of Egypt, the Netherlands, Cambodia, Syria, Sudan, and Iraq. And the report says lack of water would affect the ability to improve their economies. This is because new industries often need a large amount of water when they are beginning.
The Population Action International study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water of agriculture.
The report also says long-term solutions to the water problem must include controls on population growth. It says countries cannot provide clean water unless they slow population growth by limiting the number of children people have.From the first four paragraphs, we can learn __________.

Ever wonder how this season’s celebrations affect the environment? Guest blogger Krista Fairles takes an amusing look at this very topic:
The holidays are a wonderful, cheerful time when most people wait for Santa to bring them presents. But I’m not like most people. I spend my time wondering just what the environmental impacts of Santa Claus and his reindeer are, and more importantly, how I can calculate those impacts.
Lately I’ve been particularly curious as to whether Santa’s old sled is a clean green flying machine, or if he should be replacing his 8 reindeer with an environmentally-friendly car.
I should mention that, surprisingly, I was unable to find statistics specific to Santa’s magical flying reindeer, so these calculations use numbers from various sources and may not represent actual pollution caused by Santa and his animals. In other words, don’t complain to the government about the damage Santa is causing the environment based on this article.
Santa’s yearly trip around the globe is 44,000km long, twice the average of a North American driver. If we assume that the magic provides the altitude for this trip, then reindeer power only needs to push Santa’s sled forward. To complete the trip in 12 hours, I estimate they must travel at a speed of about 3100km/h. To travel at this speed, for this length of time, the reindeer need to eat an incredible 980 million calories each!!
So the next question is: how much food is in 980 million calories? Well, if they’re eating corn, they’d need to eat 16,500 lbs each — or 1.6 acres of food. Growing 12.8 acres of corn has its own implications for the environment that we’ll leave for another calculation.
We now need to consider that during the global trip the reindeer are “letting out” some of that corn in the form of methane (甲烷，沼气). A resting cow produces 110 kg of methane per year, so flying reindeer would each let out about 4.8 tons. With methane causing 20 times the global warming damage of CO2, and the altitude increasing that damage by 1000% that another 20 times, we can put Santa’s round-trip emissions at 15,488 tons. This is much more than the 100 tons an environmentally-friendly car would release on the same trip!
Bad Santa.Which aspect does the writer NOT include in her analyses about reindeer’s influence on environment?
| A．Distance covered. | B．Calories consumed. |
| C．Tons of waste let out. | D．Money spent on food. |
According to Paragraph 6, how many acres of corn would Santa need to feed 10 reindeer?
| A．1.6. | B．16. | C．12.8. | D．128. |
Which of the following statements would the writer most probably agree with?
| A．Christmas celebrations are really a waste of money. |
| B．Vegetarians are more likely to survive than meat-eaters. |
| C．Raising animals has a negative influence on environment. |
| D．The car industry does less harm to environment than farming. |
Which of the following words best describes the language style of the passage?
| A．Humourous and concerned. | B．Cheerful and friendly. |
| C．Academic and formal. | D．Serious and boring. |
Which of the following is the best title for this passage?

| B．Santa, watch where you’re going! |
| C．Santa Claus is coming to town! |
| D．Let’s reduce waste on Christmas celebrations! |
It is one of the most annoying words in the English language and it seems there is no escaping it. The word “huh?” is in worldwide use, a study found.
Researchers discovered that languages spoken in countries from Ghana and Laos to Iceland and Italy all include “huh?”, or something that sounds very like it. They said that while the study may sound silly, the word is an absolutely necessary part of speech. Without it and similar words, it would be impossible to show that we haven’t heard or understood what had been said and this would lead to constant misunderstandings.
But while other words used in the same context, such as “sorry” or “what”, vary widely across languages, “huh?” remains unchanged.
The Dutch researchers carefully studied ten languages from around the world, including Siwu, which is spoken in Ghana, and an Australian Aboriginal language, as well as Italian, Spanish, Dutch and Mandarin Chinese.
They analysed tapes of recorded conversations for words that sounded like “huh?” and were used to request that whatever had just been said be repeated. All contained a version of “huh?”. The word was also found in another 21 languages. While there were subtle differences in each country, all sounded basically the same.
This is surprising because normally unrelated languages will use very different words to describe the same thing. For instance, the Japanese for “dog” is “inu”, while the French is “chien”. It is thought that languages around the world have developed their own version of “huh?” because the sound is quick and simple to form, as well as being easily understood.
The researchers, said that it might seem unimportant to carry out scientific research into a word like “huh?” but in fact this little word is an essential tool in human communication. They also have an answer for those who claim that “huh?” isn’t a word. They say that it qualifies because of the small differences in its pronunciation in different languages. It also can be considered a word because it’s something we learn to say, rather than a grunt or cry that we are born knowing how to make. According to researchers, the word “huh?” is very important in speech because of ________.
| A．its stable meaning in language development |
| B．its important function in communication |
| C．its simple and easy sound and spelling |
| D．its popularity in every language |
What is the natural response if you hear the lady you’re speaking to say “huh?”?
| A．You should ask her to repeat what she says before that. |
| B．You should apologize to her for speaking in a low voice. |
| C．You should invite her to share her different views politely. |
| D．You should try to repeat what you’ve just said in a clearer way. |
The main method used in the research of “huh?” was ________.
| A．interviewing language experts in universities |
| B．talking with people from ten different countries |
| C．analyzing the recorded conversations in different languages |
| D．comparing different words with the same meaning in different languages |
According to researchers, “huh?” should be considered a word rather than a sound because ________.
| A．it is listed in most dictionaries |
| B．it is something humans learn to say |
| C．there is a clear and consistent spelling of the word |
| D．there is a big difference in the way it pronounces in different languages |
What is the purpose of the passage?
| A．To inform readers about research on the worldwide used word “huh?”. |

| D．To instruct readers of the differences of “huh?” in different languages. |
Silk production has a long and colourful history unknown to most people. Scientific discoveries have shown that silk production existed in China from around 2500 B.C., although it could be much older. For hundreds of years, China kept the secret of silk to itself as one for the most closely protected secrets in history. Anyone revealing the secret of silkworms or trying to take silkworm eggs out of ancient China was punished by death.
At one time silk was reserved only for the Chinese emperor. Gradually, others began wearing silk. In addition to being used for clothing, silk came to have industrial uses in ancient China, something that happened in the West only in modern times. Silk was used to make musical instruments, fishing lines, weapons, ropes and even paper. During the Han Dynasty silk became a form of money. Farmers paid taxes in both rice and silk. The prices of goods were calculated in lengths of silk just as they had once been calculated in gold. The importance of silk is even reflected in the Chinese language. For example, of the 5000 most common Chinese characters, around 500 have silk as their “key”.
In spite of their secrecy, the Chinese eventually lost their monopoly on silk production. It reached Korea in around 200 B.C. when immigrants from China arrived there. Silk production came to India in 300 A.D.. It was not until 500 A.D. that silk production came to Europe when travellers smuggled out silkworms in hollow tubes of bamboo. These were used to establish silk industry in Rome (modern-day Italy), although Chinese silk was still considered to be the best.
Silk was brought to Rome from China by means of the Silk Road. There were actually two Silk Roads, one over land and one on the sea. The land route in particular had a huge effect in history. All sorts of trade goods — silver, gold, jade, porcelain — passed along this road. Ideas travelled the Silk Road too. For example the religion of Buddhism was carried to China from India by traders on the Silk Road. The Silk Road created the first international culture, exposing many people to the ideas and treasures of both Western and Chinese cultures.How was China able to keep the secret of silk production?
| A．It refused to sell its silk to other countries. |
| B．Foreigners were not permitted to enter China. |
| C．The silkworms needed were not able to survive outside China. |
| D．Chinese passing on the secret to foreigners were seriously punished. |
Which of the following uses of silk is NOT mentioned in the passage?
| A．A way of purchasing goods people sold. |
| B．A material used for making different products. |
| C．A method of paying money to the government. |
| D．A valuable gift given to foreigners travelling in China. |
In what order did silk production spread throughout the world according to the passage?
| A．Europe àIndia àKorea àChina. | B．China àKorea àIndia àEurope. |
| C．China àIndia àKorea àEurope. | D．China àEurope àIndia àKorea. |

Michael J. “Crocodile Dundee” (also called Mick), played by Paul Hogan, is the main character in the fictional Crocodile Dundee film series consisting of Crocodile Dundee, Crocodile Dundee II, and Crocodile Dundee in Los Angeles. The character is a crocodile hunter, hence the nickname.
In the first film, Crocodile Dundee, Mick is visited by a New York reporter, Sue Charlton, who travels to Australia to investigate a report she heard of a crocodile hunter, who had his leg bitten off by a crocodile in the outback. The hunter supposedly walked more than a hundred miles back to civilization and miraculously survived his injuries. However, by the time she meets him, the story turns out to be a somewhat exaggerated legend where the “bitten-off leg” turns out to be just being some bad scarring on his leg; a “love bite” as Mick calls it. Still intrigued by the idea of “Crocodile Dundee”, Sue continues with the story. They travel together out to where the incident occurred, and follow his route through the bush to the nearest hospital. Despite his old-fashioned views, the pair eventually become close, especially after Mick saves Sue from a crocodile attack.
Feeling there is still more to the story, Sue invites Mick back to New York with her, as his first trip to a city (or “first trip anywhere,” as Dundee says). The rest of the film depicts Dundee as a “fish out of water,” showing how, despite his expert knowledge of living outdoors, he knows little of city life. Mick meets Sue’s boyfriend, Richard, but they do not get along. By the end of the film, Mick is on his way home, lovesick, when Sue realizes she loves Mick, too, and not Richard. She runs to the subway station to stop Mick from leaving and, by passing on messages through the packed-to-the-gills crowd, she tells him she won’t marry Richard, and she loves him instead. With the help of the other people in the subway, Mick and Sue have a loving reunion as the film ends.Which of the following statements is true about Mick?
| A．He is a crocodile hunter living in Los Angeles. |

It was terribly cold and nearly dark on the last evening of the old year, and the snow was falling fast. In the cold and the darkness, a poor little girl, with bare head and naked feet, wandered through the streets. It is true she had on a pair of slippers when she left home, but they were not of much use. They were very large, so large, indeed, that they had belonged to her mother, and the poor girl had lost them in running across the street to avoid two carriages that were rolling along at a terrible rate. One of the slippers she could not find, and a boy seized upon the other and ran away with it. So the little girl went on with her little naked feet, which were quite red and blue with the cold. In an old apron she carried a number of matches, and had a bunch of them in her hands. No one had bought anything of her the whole day, nor had any one given her even a penny.
Lights were shining from every window, and there was a delicious smell of roast goose, for it was New-year’s eve—yes, she remembered that. In a corner, between two houses, one of which projected beyond the other, she sank down and huddled（蜷缩）herself together. She had drawn her little feet under her, but she could not keep off the cold; and she dared not go home, for she had sold no matches, and could not take home even a penny of money. Her father would certainly beat her; besides, it was almost as cold at home as here.The story happened ________.
| A．on New-year Day | B．on Christmas |
| C．on a rainy evening | D．on a snowy night |
