A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely falling below 16℃. Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover, these areas would reflect more heat into the atmosphere,warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters all over the world.
In the past hundred years, humans have begun destroying rainforests in search of three major resources : land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example,a lot of carbon dioxide in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit. There are two main reasons for this. Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run it actually reduces the world’ s wood supply.Rainforests are often called the world’s drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests.
1. Rainforests can help to adjust the climate because they________.
A. reflect more heat into the atmosphere
B. bring about high rainfall throughout the world
C. rarely cause the temperature to drop lower than 16℃
D. absorb the heat from the sun, reducing the effect of heat from the sun on the earth
2. What does the word “this” underlined in the third paragraph refer to?
A. We will lose much more than we can gain.
B. Humans have begun destroying rainforests.
C. People have a strong desire for resources.
D. Much carbon dioxide comes from burning rainforests.
3. It can be inferred from the text that________.
A. we can get enough resources without rainforests
B. there is great medicine potential in rainforests
C. we will grow fewer kinds of crops in the gained land
D. the level of annual rainfall affects wind patterns
4.. What might be the best title for the text?
A. How to Save Rainforests?
B. How to Protect Nature?
C. Rainforests and the Environment.
D. Rainforests and Medical Development.

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 genetic relationship between the ancient woolly mammoth and mastodon 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 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 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 purposes. Since 1950,all African elephants have been conserved as one species. Now that we know the forest and savanna elephants are two very distinctive animals, the forest elephant should become a bigger priority(優(yōu)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 researchers’ conclusion was based on a study of the African elephant’s _____.
A. DNA B. height
C. weight D. population
3.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.
4.Which of the following can be the best title for the passage?
A. Naturalists’ Beliefs about Elephants
B. Amazing Experiments about Elephants
C. An Unexpected Finding about Elephants
D. A Long Scientific Debate about Elephants
