一、阅读理解
A recent study of ancient and modern elephants has come up with the unexpected conclusion that the African elephant is divided into two distinct (不同的) species.
The discovery was made by researchers at York and Harvard Universities when they were examining the gene tic relationship between the ancient woolly mammoth (长毛象) and mastodon (幼齿象) to modern elephants—the Asian elephant, African forest elephant and African savanna elephant.
Once they obtained DNA sequences (序列) from two fossils (化石), mammoths and mastodons, the team compared them with DNA from modern elephants.They found to their amazement that modern forest and savanna elephants are as distinct from each other as Asian elephants and mammoths.
The scientists used detailed genetic analysis to prove that the African savanna elephants and African forest elephants have been distinct species for several million years.The divergence of the two species took place around the time of the divergence of Asian elephants and woolly mammoths.This result amazed all the scientists.
There has long been debate in the scientific community that the two might be separate species, but this is the most convincing scientific evidence so far that they are indeed different species.
Previously, many naturalists believed that African savanna elephants and African forest elephants were two popu lations of the same species despite the elephants' significant size differences.The savanna elephant has an average shoulder height of 3.5 metres while the forest elephant has an average shoulder height of 2.5 metres.The savanna elephant weighs between six and seven tons, roughly double the weight of the forest elephant.But the fact that they look so different does not necessarily mean they are different species, however the proof lay in the analysis of the DNA.
Alfred Roca, assistant professor in the Department of Animal Sciences at the University of Illinois, said, “We now have to treat the forest and savanna elephants as two different units for conservation purpose.Since 1950, all African elephants have been conserved as one species.Now that we know the forest and the savanna elephant are two very distinctive animals, the forest elephant should become a bigger priority (优先) for conservation purposes.”
1．One of the fossils studied by the researchers is that of ________.
A．the Asian elephant B．the forest elephant
C．the savanna elephant D．the mastodon elephant
2．The underlined word “divergence” in Paragraph 4 means “________”．
A．evolution B．exhibition
C．separation D．examination
3．The researcher's conclusion was based on a study of the African elephant's ________.
A．DNA B．height
C．weight D．population
4．What are Alfred Roca's words mainly about
A．The conservation of African elephants.
B．The purpose of studying African elephants.
C．The way to divide African elephants into two units.
D．The reason for the distinction of African elephants.
5．Which of the following can be the best title for the passage
A．Naturalists' Beliefs about Elephants
B．Amazing Experiment about Elephants
C．An Unexpected Finding about Elephants
D．A Long Scientist Debate about Elephants

Indonesians thank volcano for eliminating pest
JAKARTA (AFP) Farmers residing on the slopes of a smoldering Indonesian volcano are thanking the mountain for getting rid of a pest that had devastated the area's coconut palms, a report here said Tuesday.
Gamkonora volcano on Halmahera island in Indonesia's North Maluku Province erupted in July, shooting rocks, ash and smoke into the air for days and prompting thousands to flee their homes.
“Almost all our coconut trees were previously ruined by the sexava pest.Now we are completely free of this pest, following Gamkonora blanketing the area with ash in July，” the state Antara news agency quoted a local farmer, Yakup, as saying.
Other areas on the same island that were not inundated by the ash continue to suffer from the pest, an insect which voraciously eats leaves of the coconut tree, greatly reducing the coconut harvest.Coconuts processed into copra are a main source of livelihood for residents in the area.
“When Gamkonora erupted, the ash it spewed made us all suffer, and many got coughs and the flu.But it turns out that this very same ash has helped us overcome this sexava pest，” said another farmer, Julis.

二、参考范文：
The report tells an interesting story that Indonesians thank a smoldering volcano for eliminating pests.Indonesians were suffering from a pest attack but thanks to the volcano eruption, they overcame the disaster.
When regarding natural disasters, people always think of words like damage, tragedy or death.We take a negative attitude towards them.However, natural disasters can also be something appreciable.Such examples can be given easily.The Nile floods the land of Egypt every year, but after the damage it seems to be, the floods actually bring rich soil and nutrition which are favorable for farming.As it's proved above, natural disasters can also do good to human beings.
However, more and more extreme weathers in recent years may bring more misfortune.A lot of people come to worry the question of declining living environment.Therefore it's high time that some effective mea sures should be taken to protect our surroundings.People should bear in their mind that we humans can not survive without the harmony of nature.
