[单项选择]In Swartkans territory, archaeologists discovered charred bone fragments dating back 1 million years. Analysis of the fragments, which came from a variety of animals, showed that they had been heated to temperatures no higher than those produced in experimental campfires made from branches of white stinkwood, the most common tree around Swartkans.
Which of the following, if true, would, together with the information above, provide the best basis for the claim that the charred bone fragments are evidence of the use of fire by early hominids
A. The white stinkwood tree is used for building material by the present-day inhabitants of Swartkans.
B. Forest fires can heat wood to a range of temperatures that occur in campfires.
C. The bone fragments were fitted together by the archaeologists to form the complete skeletons of several animals.
D. Apart from the Swartkans discovery, there is reliable evidence that early hominids used fire as many as 500 thousand years ago.
E. (E) The bone fragments were found in several distinct layers of limestone that contained primitive cutting tools known to have been used by early hominids.
[单项选择]General Wesley Clark recently discovered a hole in his personal security—his cell phone. A resourceful blogger, hoping to call attention to the black market in phone records, made his privacy rights experiment on the general in January. For $ 89.95, he purchased, no questions asked, the records of 100 cell-phone calls that Clark had made. (He revealed the trick to Clark soon after. ) "It’s like someone taking your wallet or knowing who paid you money", Clark says. "It’s no great discovery, but it just doesn’t feel right." Since then, Clark has become a vocal supporter of the movement to outlaw the sale of cell-phone records to third parties.
The U. S.’s embrace of mobile phones—about 65% of the population are subscribers—has far outpaced efforts to keep what we do with them private. That has cleared the way for a cottage industry devoted to exploiting phone numbers, calling records and even the locations of unsuspecting subscribers for profit. A second business segment is develop
A. to earn money from the internet
B. to blackmail the general for money
C. to play a trick on the general
D. to warn people of the information security
[单项选择]X-ray examination of a recently discovered painting — judged by some authorities to be a self-portrait by Vincent van Gogh — revealed an underimage of a woman’s face. Either van Gogh or another painter covered the first painting with the portrait now seen on the surface of the canvas. Because the face of the woman in the underimage also appears on canvases van Gogh is known to have painted, the surface painting must be an authentic self-portrait by van Gogh.
The conclusion above is properly drawn if which of the following is assumed
A. If a canvas already bears a painted image produced by an artist, a second artist who uses the canvas to produce a new painting tends to be influenced by the style of the first artist.
B. Many painted canvases that can be reliably attributed to van Gogh contain underimages of subjects that appear on at least one other canvas that van Gogh is known to have painted.
C. Any painted canvas incorrectly attributed to van Gogh would not contain an underimage of a subject that appears in authentic paintings by that artist.
D. A painted canvas cannot be reliably attributed to an artist unless the authenticity of any underimage that painting might contain can be reliably attributed to the artist.
E. (E) A painted canvas cannot be reliably attributed to a particular artist unless a reliable X-ray examination of the painting is performed.
[单项选择]Archaeologists have found wheeled ceramic toys made by the Toltec, twelfth-century inhabitants of what is now Veracruz. Although there is no archaeological evidence that the Toltec used wheels for anything but toys, some anthropologists hypothesize that wheeled utility vehicles were used to carry materials needed for the monumental structures the Toltec produced.
Which of the following, if true, would most help the anthropologists explain the lack of evidence noted above
A. The Toltec sometimes incorporated into their toys representations of utensils or other devices that served some practical purpose.
B. Any wheeled utility vehicles used by the Toltec could have been made entirely of wood, and unlike ceramic, wood decays rapidly in the humid climate of Veracruz.
C. Carvings in monument walls suggest that the Toltec’s wheeled ceramic toys sometimes had ritual uses in addition to being used by both children and adults as decorations and playthings.
D. Wheeled utility vehicles were used during the twelfth century in many areas of the world, but during this time wheeled toys were not very common in areas outside Veracruz.
E. (E) Some of the wheeled ceramic toys were found near the remains of monumental structures.

For as long as there have been archaeologists, there have been guesses about what they would discover if they were to analyze their own society’s refuse(垃圾) Which such speculations (沉思) often have been humors, they are based on a serious rationale (方式) Archaeologists have learned improtant information about past societies by analyzing the patterns, in arivent garbage (方式) so they should be able to learn something about contemporary societies from fresh garbage. Just as the pieces of pottery (陶器)broken stone tools, and cut animal bones in old refuse middens(垃圾堆)provide a surprisingly detailed (详细的) view of past life styles, so should the labeled packages, food debris (核骸) discarded (抛弃) clothing, and used batteries (电池) in modem middens reveal intimate (个人的)details of our lives today.

C. is just a guess for it is impossible for archaeologists to do such a thing
D. is interesting because archaeologists can’t learn anything while doing so
