托福阅读真题1
It is estimated that over 99 percent of all species that ever existed
have become extinct. What causes extinction? When a species is no
longer adapted to a changed environment, it may perish. The exact
causes of a species death vary from situation to situation. Rapid
ecological change may render an environment hostile to a species. For
example, temperatures may change and a species may not be able to
adapt. Food resources may be affected by environmental changes, which
will then cause problems for a species requiring these resources. Other
species may become better adapted to an environment, resulting in
competition and, ultimately, in the death of a species.
The fossil record reveals that extinction has occurred throughout
the history of Earth. Recent analyses have also revealed that on some
occasions many species became extinct at the same time — a mass
extinction. One of the best-known examples of mass extinction occurred
65 million years ago with the demise of dinosaurs and many other forms
of life. Perhaps the largest mass extinction was the one that occurred
225 million years ago, when approximately 95 percent of all species died,
1
mass extinctions can be caused by a relatively rapid change in the
environment and can be worsened by the close interrelationship of many
species. If, for example, something were to happen to destroy much of
the plankton in the oceans, then the oxygen content of Earth would drop,
affection even organisms not living in the oceans. Such a change would
probably lead to a mass extinction.
One interesting, and controversial, finding is that extinctions during
the past 250 million years have tended to be more intense every 26
million years. This periodic extinction might be due to intersection of the
Earths orbit with a cloud of comets, but this theory is purely speculative.
Some researchers have also speculated that extinction may often be
random. That is, certain species may be eliminated and others may
survive for no particular reason. A species survival may have nothing to
do with its ability or inability to adapt. If so, some of evolutionary history
may reflect a sequence of essentially random events.

托福阅读真题2
Archaeological discoveries have led some scholars to believe that
the first Mesopotamian inventors of writing may have been a people the
later Babylonians called Subarians. According to tradition, they came
from the north and moved into Uruk in the south. By about 3100 B.C.,
5
they were apparently subjugated in southern Mesopotamia by the
Sumerians, whose name became synonymous with the region
immediately north of the Persian Gulf, in the fertile lower valleys of the
Tigris and Euphrates. Here the Sumerians were already well established
by the year 3000 B.C. They had invented bronze, an alloy that could be
cast in molds, out of which they made tools and weapons. They lived in
cities, and they had begun to acquire and use capital. Perhaps most
important, the Sumerians adapted writing (probably from the Subarians)
into a flexible tool of communication.
Archaeologists have known about the Sumerians for over 150 years.
Archaeologists working at Nineveh in northern Mesopotamia in the
mid-nineteenth century found many inscribed clay tablets. Some they
could decipher because the language was a Semitic one (Akkadian), on
which scholars had already been working for a generation. But other
tablets were inscribed in another language that was not Semitic and
previously unknown. Because these inscriptions made reference to the
king of Sumer and Akkad, a scholar suggested that the new language be
called Sumerian.
But it was not until the 1890s that archaeologists excavating in
city-states well to the south of Nineveh found many thousands of tablets
inscribed in Sumerian only. Because the Akkadians thought of Sumerian
as a classical language (as ancient Greek and Latin are considered today),
6
they taught it to educated persons and they inscribed vocabulary,
translation exercises, and other study aids on tablets. Working from
known Akkadian to previously unknown Sumerian, scholars since the
1890s have learned how to read the Sumerian language moderately well.
Vast quantities of tablets in Sumerian have been unearthed during the
intervening years from numerous sites.
1. According to the passage , the inventors of written language in
Mesopotamia were probably
the
(A) Babylonians
(B) Subarians
(C) Akkadians
(D) Sumerians
2. The word subjugated in line 4 is closest in meaning to
(A) distinguished
(B) segregated
(C) concentrated
(D) conquered

(A) equivalent to
(B) important for
(C) respected in
