It’s spring again, and it’s the season of fireflies (萤火虫). Their warm and gentle lights glitter in the quiet (dark), especially in mountainous areas or near water. No matter
you are, or how old you are, you’re sure to fall under their spell.
For many older people, fireflies are a reminder of childhood. That’s because they were a lot common long ago,
the industrial development destroyed so much firefly habitat. Wetlands
(appear) and chemicals were dumped into rivers. Fireflies were left with
to feed or breed. What’s more, fireflies seem to keep away
artificial lights. As these spread, the bugs retreated. Not until they had almost vanished
(do) people realize what was happening.
Over the past few years, though, conservation groups and enthusiastic firefly lovers have come together to save these special creatures, are making a comeback. In natural settings all around the island, fireflies are once again lighting up the night and
(help) create special memories for the next generation.

The Koran
Most religions have some kind of holy text on which the religious beliefs are based．For Christians this text is the Holy Bible; for Jews it is the Torah and for Muslims it is the Koran.
Muslims believe that the Koran(consist) of revelations from God to Muhammad during the years 610 to 632 when Muhammad died．These revelations were written down by those
were close to him during this time and for several years after his death．They were gathered into the text
(know) as the Koran during the years 630 to 650.
The interpretation of the Koran has always been a difficult task, even for Islamic scholars．For example, the meanings of some words are determined by dots above the vowels(元音)．In ancient Arabic, however, very often these dots (omit)．As a result some letters looked identical．Thus, the meanings of these words depended in many cases
the memories of the men who had written them．Early Muslims had to try to get the exact meanings of the words
these people died and it was too late.
Unlike the Bible, in which the events are provided in time order, there is no reference tothings occurred in the Koran．In any case, unlike the Bible, most the suras - sections - are composed of orders and warnings．Unlike in the Bible, there are very few stories in the Koran．
Muslims believe that by (recite) the book, they create a holy atmosphere, and there are many Muslims who have learned the Koran by heart.

Scientists have discovered that(stay) in the cold could help us lose weight．Researchers at the University of California found that exposure to the cold increases levels of a protein that helps form brown fat--the type of fat that produces heat and keeps us warm．Brown fat burns energy,
helps us lose weight．White fat stores extra energy, which results
weight gain．The researchers said that because air conditioning and heating give us constant,
(comfort) temperatures, our body’s need for brown fat has decreased． They found that: “Outdoor workers in northern Finland who
(expose) to cold temperature have
significant amount of brown fat when
(compare) to same-aged indoor workers.” The research was conducted on two different control groups of mice．
group was injected with the protein that helps create brown fat．This group later gained 30% less weight after both groups were fed high-fat diets．The researchers say this could be good news in the fight against obesity．People who are obese have
(low) levels of brown fat than thinner people．Head researcher Hei Sook Sul said, “This protein could become an important target for research into the treatment and prevention of obesity and obesity-related diseases.” She added, “If you can somehow increase levels of this protein, you could
(possible) lose more weight even if eating the same amount of food.”
