A
A recent study of ancient and modern elephant 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 University when they were examing the genetic relationship between the ancient woolly mammoth and mastodon 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 compated them with DNA from modern elephants. They found 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 elephant and the African forest elephant 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 populations 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 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.
Alfried 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 difficult units for conservation purpose. Since 1950, all African elephants have been conserved as one species. Now that we know the forest and savanna elephants have been distinct animals, the forest elephant should become a bigger priority(优先)for conservation purposes.”
36．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
37．The underlined word “divergence” in Paragraph 4 means“________”．
A．evolution B．exhibition
C．separation D．examination
38．The researchers' conclusion was based on a study of the African elephant's________.
A．DNA B．height
C．weight D．population
39．What are Alfred Roca's words mainly about?
A．The conservation of African elephant.
B．The purpose of studying African elephant.
C．The way to divide African elephants into two units.
D．The reason for the distinction of African elephants.
40．Which of the following can be the best title for the passage?
A．Naturalist' Beliefs about Elephants
B．Amazing Experiments about Elephants
C．An Unexpected Finding about Elephants
D．A Long Scientific Debate about Elephants
B
What will power your house in the future？Nuclear，wind，or solar power？According to scientists at the Massachusetts Institute of TechnologyMIT)in the US，it might be leaves—but artificial(人造的)ones.
Natural leaves are able to change sunlight and water into energy.It is known as photosynthesis(光合作用)．Now researchers have found a way to imitate this seemingly simple process.
The artificial leaf developed by Daniel Nocera and his colleagues at MIT can be seen as a special silicon chip with catalysts(催化剂)．Similar to natural leaves，it can split water into hydrogen and oxygen when put into a bucket of water.The hydrogen and oxygen gases are then stored in a fuel cell，which uses those two materials to produce electricity，located either on top of a house or beside the house.
Though the leaf is only about the shape of a poker card，scientists claimed that it is promising to be an inexpensive source of electricity in developing countries.“One can imagine villages in India and Africa not long from now purchasing an affordable basic power system based on this technology，”said Nocera at a conference of the American Chemical Society.
The artificial leaf is not a new idea.The first artificial leaf was invented in 1997 but was too expensive and unstable for practical use.The new leaf，by contrast，is made of cheap materials，easy to use and highly stable.In laboratory studies，Nocera showed that an artificial leaf prototype(原型)could operate continuously for at least 45 hours without a drop in activity.
The wonderful improvements come from Nocera's recent discovery of several powerful，new and inexpensive catalysts.These catalysts make the energy transformation inside the leaf more efficient with water and sunlight.Right now，the new leaf is about 10 times more efficient at carrying out photosynthesis than a natural one.Besides，the device can run in whatever water is available；that is，it doesn't need pure water.This is important for some countries that don't have access to pure water.
With the goal to “make each home its own power station” and “give energy to the poor”，scientists believe that the new technology could be widely used in developing countries，especially in India and rural China.
41.Which of the following orders correctly shows how the artificial leaf is used to produce electricity?
a．artificial leaves split water into hydrogen and oxygen
b．the hydrogen and oxygen gases are stored in a fuel cell
c．the artificial leaves are put in water
d．the fuel cell uses hydrogen and oxygen to produce electricity
A．c，b，a，d B．c，a，b，d
C．b，c，a，d D．c，a，d，b
42.Which of the following statements about new artificial leaves is NOT WRONG according to the article?
A．They are inexpensive but unstable.
B．They are as efficient at carrying out photosynthesis as natural leaves.
C．They can work only in pure water.
D．They need several catalysts to help them work efficiently.
43．The purpose of the scientists at MIT in developing the new artificial leaf is to________.
A．build up more power stations in the world
B．provide cheaper energy for developing countries
C．offer people in developing countries access to pure water
D．gain a deeper understanding of the photosynthesis process
44．The main idea of this passage is ________.
A．an introduction to the history of artificial leaves
B．an invention copying photosynthesis
C．giving energy to the poor
D．a mixture of water power and solar energy
45.．The underlined word “imitate” in Paragraph 2 can be replaced by “________”．
A．produce B．hold C．prevent D．copy
