We might not be alone in the universe. Actually, it may be confirmed as a very crowded place by new computer models developed to help identify habitable planets.
Estimates of places where life can exist have been based on the possibility of them having surface water. But software recently developed by the Aberdeen University allows researchers to identify planets with underground water kept liquid by heat from planets.
Water is fundamental for life and planets too close to the sun lose water to the atmosphere through evaporation. On the other hand, planets located in distant reaches from their star have their surface water locked away as ice.
Sean McMahon, who is carrying out the work, explained: "Traditionally people have said that if a planet is in this Goldilocks zone—not too hot and not too cold—then it can have liquid water on its surface and be habitable."
But this concept might change when considering that planets can receive two sources of heat—heat direct from the star and heat generated deep inside the planet.
It is easy to observe it in our own planet. As you go down through the crust (壳) of the Earth, the temperature gets higher and higher. Even when the surface is frozen, water can exist below ground.
There could be immense quantities of water in fact—full of primitive life.
Professor John Parnell, also from Aberdeen University said: "There is a significant habitat for microorganisms below the surface of the Earth, extending down several kilometres".
"And some believe that the majority of life on Earth could even reside in this deep biosphere."
So the Aberdeen team are developing models to predict which distant planets might harbour underground reservoirs of liquid water with the possibility of alien life.What is considered as the symbol of life existence traditionally?
| A．Solid water on its surface. | B．Solid water below ground. |
| C．Liquid water below ground. | D．Liquid water on its surface. |
Why did John Parnell mention the fact about Earth?
| A．To prove that there is majority of life on Earth. |
| B．To prove that life may also exist in other planets. |
| C．To prove that there is primitive life down through Earth. |
| D．To prove that there is a habitat for microorganisms below Earth. |
What theory is the Aberdeen team’s study based on?
| A．Planets can lose water through evaporation. |
| B．Planets can receive heat direct from the star. |
| C．Planets can have their surface water locked away as ice. |
| D．Planets can receive heat generated deep inside the planet. |
What can we know about the computer models?
| A．They will help identify planets where there is life. |
| B．They will help researchers find Goldilocks zones. |
| C．They have helped find some significant discoveries. |
| D．They have already located some habitats for life. |
“Before you fall in love, you'd better get a job”
As told by Lee Joon-ho, 20, a senior in law at Seoul National University
Korean TV dramas have shown a lot of rebellious(反叛的) youth, but in fact most students still live a traditional life.
Confucianism has a great influence on us. For instance, Confucius said that we should be dutiful to our parents and value the family. Thus we prefer a school that's close to home so we can go back every day.
Also as a result of Confucianism, teachers enjoy a high status in Korea. The other day, my professor was flying to Vienna on a business trip. Instead of waiting for hours in the queue, he was told to check in first and didn't have any problem with overweight luggage.
When it comes to important decision-making, such as choosing a university, a job, and a wife, we listen to our parents' suggestions. Most parents seem liberal in study decisions, but they take a firmer attitude towards their children's love and marriage choices. Often, a man has to have his own business or a solid career before he's allowed to pursue romance.
Male chauvinism is popular among our parents' generation, since they had to support the whole family through hard work. We need to shoulder the same responsibility, but we've also learned to respect women, as they're doing outstanding work in lots of areas. But to be honest, my friends and I still prefer a traditional woman as a girlfriend and future wife. We want her to be elegant and thoughtful in taking care of a family.
Our sense of tradition is also reflected in our buying habits. In my house, you see only Korean appliances. Although European cell phones are available in ROK, we favor LG and Samsung, which are suited more to our tastes and widely promoted in TV dramas and films.The professor was told to check in first because _________.
| A．His luggage was overweight. |
| B．He had waited for hours. |
| C．People respect teachers in Korea. |
| D．He was on a business trip. |
Which of the statements is true according to the passage?
| A．Generally speaking, men need to support the whole family in Korea. |
| B．Korean women have no freedom in choosing husbands. |
| C．Male chauvinism is popular among young people now. |
| D．Young people are out of control of their parents. |
From the last paragraph we can learn that _________.
| A．You can not find European cell phones in Korea. |
| B．You can see advertisements for LG and Samsung in Korean TV dramas and films. |
| C．Korean cell phones are traditional. |
| D．The Korean people have a sense of tradition. |
What is the passage mainly about?
| A．Korean youth are rebellious. |
| B．Korean youth will not love anyone until they find a job. |
| C．Most Korea students live a traditional life. |
| D．Confucius has a great influence on the Korean people. |
Edmund Halley was an English scientist who lived over 200 years ago . He studied the observations of comets (彗星) which other scientists had made . The orbit（轨道） of one particular comet was a very difficult mathematical problem. He could not figure it out. Neither could other scientists who dealt with such problems.
However , Halley had a friend named Newton, who was a brilliant (有才华的) mathematician .Newton thought he had already worked out that problem, but he could not find the papers on which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse (椭圆) .
Now Halley set to work .He figured out the orbits of some of t
he comets that had been observed by scientists. He made a surprising discovery. The comets that had appeared in the years 1531, 1607, and 1682 all had the same orbit. Yet their appearances had been 75 to 76 years apart (相隔).
This seemed very strange to Halley. The different comets followed the same orbit. The more Halley thought about it, the more he thought that there had not been three different comets, as people thought. He decided that they had simply seen the same comet three times .The comet had gone away and had come back again.
It was an astonishing idea! Halley felt certain enough to make a prediction of what would happen in the future. He decided that this comet would appear in the year 1758. There were 53 years to go before Halley’s prediction could be tested .In 1758 the comet appeared in the sky. Halley did not see it, for he had died some years before. Ever since then that comet has been called Halley’s comet, in his honor.Edmund Halley figured out the orbit of.
| A．some different comets appearing several times |
| B．the same comet appearing at different times |
| C．three different comets appearing three times |
| D．several comets appearing at the same time |
Halley made his discovery.
| A．by doing experiments |
| B．by means of his own careful observation |
| C．by using the work of other scientists |
| D．by chance |
Halley made a surprising, but correct prediction in the year.
| A．1704 | B．1705 | C．1706 | D．1707 |
According to the passage, which of the flowing is NOT true?
| A．Newton figured out the orbit of the comet . |
| B．Halley figured out the orbit of the comet first. |
| C．Newton gave Halley some help . |
| D．Halley died before 1758. |

I’m a pig, and my son is a rabbit. I have snakes for daughters, and my wife, believe it or not, is a dragon! Do I live in a zoo? No, of course not! I am talking about Chinese zodiac signs（十二生肖）. Depending on the year of your birth, each person has an animal for a sign. That’s why I am a pig and my wife is a dragon. If you, like me, were born in the year of the pig, then you are brave, thoughtful and loyal. The year of the pig is filled with good fortune.
Now let’s take a closer look at this interesting animal.
Pigs were first raised by man about 9,000 years ago, and are still a very common farm animal in many parts of the world. We don’t just use pigs for their meat — almost every part of the animal is used. The hair is used for artists’ brushes. The fat is used to make floor wax, rubber and plastics.
Pigs have also been important in the world of entertainment. In 1995 the film ‘Babe’ starred a loveable talking pig as its main character. The film won an Oscar and was nominated （提名）for 6 more. In England you can even go to watch pig racing. A farmer, Rob Shepherd, has been raising money for charity by holding pig races on his farm. The events have been very successful. People don’t just want to eat pigs, it seems!
Pigs also play an important role in the English language. For example, if someone says that he will travel to the sun one day, you can say “pigs might fly!” to him. Hungry? Well then, you can “pig out” and eat lots of food. And what if someone rescues you? Well, you can say that they “saved your bacon”. The writer wrote the first paragraph in a ______ tone.
| A．sad | B．confused | C．serious | D．humorous |
We may know from the passage that ______.
| A．people in England like pigs more than other animals |
| B．pigs are more useful than ordinary people imagine |
| C．pigs are the first animals raised by man |
| D．more people don’t want to eat pigs now |
The underlined sentence “pigs might fly!” in the fifth paragraph means “______”.
| A．What you have just said is impossible |
| B．Pigs are great animals |
| C．I don’t understand your words |
| D．I can’t agree with you more |
