Scientists believe that conditions on Mars around 3.8 billion years ago were very similar to those of the early earth, when primitive organisms were spreading through our oceans. At that time, Mars would have been much warmer and wetter than it is today, with an atmosphere composed mainly of carbon dioxide, just like that of the earth at the time. Under these conditions, it is highly probable that life may have arisen on Mars as well.
But, even if life did not arise naturally on Mars, it does not mean that it could not have existed there. According to Professor Paul Davies of the University of Adelaide, Australia, life forms could have been transferred between the earth and Mars in wreckage (broke pieces) created by the impact of comet(彗星) and small planets on the surface of the two planets.
Even today, about 500 tons of material from Mars lands on earth every year. It is mainly in the form of the dust but occasionally a larger chunk(厚片，大块) strikes the earth. In 1911, a piece of Martian rock crashed in Egypt, killing a dog. According to Professor Davies, it is in these chunks of rock, which were much larger and more frequent in the past that life forms could have been transported from planet to planet.
“But how could these life forms have survived their journey through space?” says Paul Davies, “The difficulty in believing this theory is that a bacterium on its own in space has to struggle itself not only against cold but also against deadly cosmic (宇宙的) radiation. But wrapped in a rock the situation is different. A rock ten meters across would shield life inside it from a lot of radiation and the temperature might only be minus 10 or 20 degrees, the sort of thing we have on earth.”Where do some scientists suppose life probably come from?

Why do Americans struggle with watching their weight, while the French, who consume rich food, continue to stay thin? Now a research by Cornell University suggests how life style and decisions about eating may affect weight. Researchers concluded that the French tend to stop eating when they feel full. However, Americans tend to stop when their plate is empty or their favorite TV show is over.
According to Dr. Joseph Mercola, a health expert, the French see eating as an important part of their life style. They enjoy food and therefore spend a fairly long time at the table, while Americans see eating as something to be squeezed between the other daily activities. Mercola believes Americans lose the ability to sense when they are actually full. So they keep eating long after the French would have stopped. In addition, he points out that Americans drive to huge supermarkets to buy canned and frozen foods for the week. The French, instead, tend to shop daily, walking to small shops and farmers’ markets where they have a choice of fresh fruits, vegetables, and eggs as well as high-quality meats for each meal.
After a visit to the United States, Mireille Guiliano, author of French Women Don’t Get Fat, decided to write about the importance of knowing when to stop rather than suggesting how to avoid food. Today she continues to stay slim and rarely goes to the gym.
In spite of all these differences, evidence shows that recent life style changes may be affecting French eating habits. Today the rate of obesity(肥胖症) — or extreme overweight — among adults is only 6%. However, as American fast food gains acceptance and the young reject older traditions, the obesity rate among French children has reached 17% — and is growing.In what way are the French different from Americans according to Dr. Joseph Mercola?
| A．They go shopping at supermarkets more frequently. |
| B．They squeeze eating between the other daily activities. |

Trees are useful to man in three important ways: they give him wood and other useful things, they give him cool places, and they help to stop drought and flood.
Unluckily, in many parts of the world, man has not found that the third of these points is the most important. Man wants to make money from trees, so he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And also, he is usually too careless to plant and look after new trees. So the forests slowly disappear.
This does not only mean that man will have fewer trees. The results are even worse: for where there are trees, their roots break up soil---make the rain in ---and also bind（凝固） the soil, thus stopping it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the topsoil is gone, nothing is left but useless desert.The most important points of trees to man is ________.
| A．they help him to make money |
| B．they give him cool |
| C．they give him wood and other things |

| B．there are too many rainfalls |
| C．strong winds bring a lot of sand |
| D．there are no longer trees to keep the rain and protect the top-soil. |

Tourism probably started in Roman times. Rich Romans visited friends and family who were working in another part of the Roman empire. When the empire broke down, this kind of tourism stopped.
In the early 17th century, the idea of the "Grand Tour" was born. Rich young English people sailed across the English Channel. They visited the most beautiful and important European cities of the time, including Paris in France, and Rome and Venice in Italy. Their tours lasted for two to four years, and the tourists stayed a few weeks or months in each city. The "Grand Tour" was an important part of young people's education-but only for the rich.
In the 18th century, tourism began to change. For example, people in the UK started to visit some towns, such as Bath to "take the waters". They believed that the water there was good for their health. So large and expensive hotels were built in these towns.
In the 19th century, travel became much more popular and faster. When the first railways were built in the 1820s, it was easier for people to travel between towns, so they started to go for holidays at the seaside. Some started to have holidays in the countryside as cities became larger, noisier and dirtier.
Traveling by sea also became faster and safer when the first steamships were built. People began to travel more to faraway countries.
The 20th century saw cars become more and more popular among ordinary people. Planes were made larger, so ticket prices dropped and more people used them.
Thus tourism grew. In 1949, Russian journalist Vladimir Raitz started a company called Horizon Holidays. The company organizes everything-plane tickets, hotel rooms, even food-and tourists pay for it all before they leave home. The package tour (包办旅行) and modern tourism industry was born.
The first travel agency in China was set up as early as 1949. But tourism did not take off until 1978. In 2002, the industry was worth 500 billion yuan and became an important part of China's social development.In the early times, the travelers _______ .
| A．all came from China |
| B．were very young and strong |

| C．China’s tourism did not take off until 1949. |
| D．In 2002 , the tourism industry became an important part of China’s social development. |
Modern tourism industry was born _______
| A．in 1949 |
| B．in Roman times |

A 8.2-magnitude（震级）earthquake struck off the coast of northern Chile late on Tuesday, cutting power and leading to small landslides and a tsunami (海啸). Four men and one woman died —two who suffered heart attacks and three who were crushed（压死). About 300 prisoners escaped from the northern port city of Iquique in the immediate aftershock (余震).
The quake struck at about 8:46 p.m. local time, some 60 miles northwest of Iquique. It had a depth of 12.5 miles. Chile’s National Emergency Office asked coastal residents to leave for safe places. “The fact is, we will know the extent of the damage as time goes by and when we inspect the areas in the light of day,” Chile’s President Michelle Bachelet said early on Wednesday. “The country has faced these first emergency hours very well.”
Residents in the port city of Antofagasta walked calmly through the streets to higher ground as traffic became heavy in some places. “Many people are fearful after experiencing the powerful earthquake in 2010, so they immediately rushed to higher ground when they heard the tsunami warning,” said a government official.”There have been lots of aftershocks and communications have been cut off in many of the affected areas. So people are waiting in the dark hills, not knowing what is to come, and hoping they will be able to return to their homes safely.”
The Pacific Tsunami Warning Center sent our several tsunami warnings, but called off all of them by early Wednesday.
