Previous studies of rocks from the Earth and the Moon have been unable to distinguish between the two, suggesting that they formed from the same material. But this still left room for a number of theories explaining how—for example, that the Moon and Earth formed from the same material at the same time. It was even suggested that the early Earth spun so fast it formed a bulge that eventually broke off to form. the Moon.
Franck Poitrasson, and his colleagues at the Swiss Federal Institute of Technology have compared Moon rocks with rocks from Earth and discovered a surprising difference. They analysed the weight of the elements present in the rock using a highly accurate form. of mass spectroscopy(光谱研究) that involves vaporising a sample by passing it through an argon (氩) flame. Although they appeared very similar in most respects, the Moon rocks had a higher ratio of iron-57 to iron-54 isotopes(同位素)than the Earth rocks. "The only way we could explain this difference is that the Moon and the Earth were partly vaporised during their formation," says Poitrasson.
Only the popular "giant planetary impact" theory could generate the temperatures of more than 1700℃ needed to vaporise iron. In this scenario, a Mars-sized planet known as Theia crashed into Earth 50 million years after the birth of the Solar System. This catastrophic collision would have released 100 million times more energy than the impact believed to have wiped out the dinosaurs—enough to melt and vaporise a large portion of the Earth and completely destroy Theia. The debris from the collision would have been thrown into orbit around the Earth and eventually coalesced to form. the Moon.
When iron is vaporised, the lighter isotopes burn off first. And since the ejected debris that became the Moon would have been more thoroughly vaporised, it would have lost a greater proportion of its lighter iron isotopes than Earth did. This would explain the different ratios that Poitrasson has found.
The main theme of the passage is ______.
A.the differences between the Earth and the Moon
B.how man manages to set foot onto the Moon
C.the collision between the Earth and the Moon
D.the origin of the Moon

In his West African homeland, Mr. Jallow&39; s salary was the equivalent of just 50 euros a month, barely enough for the necessities, he said. And everywhere in his neighborhood in Serekunda, Gambia&39; s largest city, there was talk of easy money to be made in Europe.
Now he laughs bitterly about all that talk. He lives in a patch of woods here in southern Spain, just outside the village of Palos de la Frontera, with hundreds of other immigrants. They have built their homes out of plastic sheeting and cardboard, unsure if the water they drink from an open pipe is safe. After six years on the continent, Mr. Jallow is rail thin, and his eyes have a yellow tinge.
“We are not bush people,” he said recently as he gathered twigs to start a fire. “You think you are civilized. But this is how we live here. We suffer here.”
The political upheaval in Libya and elsewhere in North Africa has opened the way for thousands of new migrants to make their way to Europe across the Mediterranean. Already some 25,000 have reached the island of Lampedusa, Italy, and hundreds more have arrived at Malta.
The boats, at first, brought mostly Tunisians. But lately there have been more sub-Saharans.
Experts say thousands more — many of whom have been moving around North Africa trying to get to Europe for years, including Somalis, Eritreans, Senegalese and Nigerians — are likely to follow, sure that a better life awaits them.
But for Mr. Jallow and for many others who arrived before them, often after days at sea without food or water, Europe has offered hardships they never imagined. These days Mr. Jallow survives on two meals a day, mostly a leaden paste made from flour and oil, which he stirs with a branch.
“It keeps the hunger away,” he said.
The authorities estimate that there are perhaps 10,000 immigrants living in the woods in the southern Spanish province of Andalusia, a region known for its crops of strawberries, raspberries and blueberries, and there are thousands more migrants in areas that produce olives, oranges and vegetables. Most of them have stories that echo Mr. Jallow&39; s.
From the road, their encampments look like igloos tucked among the trees. Up close, the squalor is clear. Piles of garbage and flies are everywhere. Old clothes, stiff from dirt and rain, hang from branches.
“There is everything in there,” said Diego Canamero, the leader of the farm workers&39; union in Andalusia, which tries to advocate for the men. “You have rats and snakes and mice and fleas.”
The men in the woods do not call home with the truth, though. They send pictures of themselves posing next to Mercedes cars parked on the street, the kind of pictures that Mr. Jallow says he fell for so many years ago. Now he shakes his head toward his neighbors, who will not talk to reporters.
“So many lies,” he said. “It is terrible what they are doing. But they are embarrassed.”
Even now, though, Mr. Jallow will not consider going back to Gambia. “I wouldprefer to die here,” he said. “I cannot go home empty-handed. If I went home, they would be saying, "What have you been doing with yourself, Amadou" They think in Europe there is money all over.”
The immigrants — virtually all of them are men — cluster by nationality and look for work on the farms. But Mr. Canamero says they are offered only the least desirable work, like handling pesticides, and little of it at that. Most have no working papers.
Occasionally, the police bring bulldozers to tear down the shelters. But the men, who have usually used their family&39; s life savings to get here, are mostly left alone — the conditions they live under are an open secret in the nearby villages.
