About 12,000 years ago- long before the famous UFO crash make headlines in America—an alien spaceship crashed in China. And their descendants are still living in a faraway Chinese village today! That is the mind-bending claim made in the new book Out of Time and Place, a collection of reports from the files of Fate, a magazine edited by Terry O’Neil.
The story first came to light in 1937 when an expedition led by Chi Pu-Tei came across a group of caves deep in the Bayan-Kara-Ula Mountains. In the caves were found strange-looking skeletons with big heads and small, slender bodies—closely matching typical descriptions of space aliens. The explorers also uncovered 716 mysterious stone discs with strange hieroglyphics(象形文字) on them.
In Qinghai Province, where the mountains lie, ancient stories tell of small, skinny beings with oversize heads who came from the sky long long ago. And to this day, locals live in fear of attack from strange-looking creatures from above.
And there is more. In 1947, British scientist Karyl Robin-Evans led an expedition into the mountains and discovered a group of dwarfs(侏儒) who called themselves the Droza. “They told him that their ancestors came from a planet in the Sirius（天狼星）system and crashed in this mountain area a long time ago,” writes Hausdorf, “Many of them were killed, but survivors adapted to living on this rough planet far from home.”
For decades, Robin-Evans’ claims were dismissed as nonsense. But in 1995, the Associated Press reported that in the region a village named Huilong had been discovered—populated by 120 dwarfs ranging from 3-foot-10 to 2-foot-1tall.Hausdorf asks, “Could these people be the last living descendants of the survivors of the legendary UGO crash—the Chinese Roswell?”

Babies born in summer are more likely to become short-sighted in late life, a study has shown.

As many as a quarter of all cases of short-sightedness are caused by too great an exposure to sunlight in the first weeks of life, say eye experts.

They are advising all parents to put sunglasses on their babies during the first weeks.

Scientists had already established that over-exposure to sunlight caused shortsightedness in animals.

Researchers who compared the months in which babies were born with whether they needed glasses later on say the principle also applies to humans.

A study of almost 300,000 young adults-the largest of its kind-showed that those born in June and July had a 25 per cent greater chance of becoming severely short-sighted than those born in December or January.

Research leader Professor Michael Belkin, of Tel Aviv University, said it was because prolonged illumination(光照) causes the eyeball to lengthen-causing short-sightedness.

Hence the more light a newborn is exposed to, the more the eyeball lengthens and the worse the short-sightedness will be.

The mechanism which lengthens the eyeball is associated with levels of melatonin(褪黑激素), a pigment (色素) which protects the skin against harmful rays of the sun.

In young babies not enough melatonin is released as protection, meaning they are more vulnerable to sunburn and changes to eyeball shape.

Sight expert Professor Daniel O’Leary, of Anglia Ruskin University in Cambridge, said “At the moment we don’t know the precise cause of why light exposure affects sight, but the evidence seems to prove that it is one of the reasons for people becoming shortsighted.”

67. Babies born in summer are more likely to be shortsighted ____________.

A. because the summer sun is too strong for babies

B. because babies born in summer have lengthened eyeballs

C. if they are exposed to much sunlight in the first weeks after they are born

D. if parents don’t know a proper way to protect their babies’ eyes

68. Melatonin is a kind of material to ___________.

A. prevent the eyes from becoming near-sighted

B. protect the skin from harmful sun rays

C. make our body strong

D. protect babies’ eyes from summer sun

69.From what Professor Daniel O’Leary says we can conclude that ___________.

A. there is no evidence that shortsightedness is related to exposure to sunlight

B. whether light exposure affects sight still needs to be further proved

C. he believes that light exposure can cause shortsightedness

D. he tries to give the cause of why light exposure affects sight

70.The underlined word “vulnerable” in the passage probably means __________.

A. easy to be harmed B. resistant

C. protective D. changeable
