问题 单项选择题

某市规定,出租车合乘部分的车费向每位乘客收取显示费用的60%,燃油附加费由合乘客人平摊。现有从同一地方出发的三位客人合乘,分别在D、E、F点下 车,显示的费用分别为10 元、20 元、40元。那么在这样的合乘中,司机的营利比正常(三位客人是一起的,只是分别在上述三个地方下车)多()。

A. 2元

B.10元

C.12元

D.15元

答案

参考答案:B

解析:在D点下车时,司机可以收到的费用为10×60%×3=18(元),到E点时,可收到的费用为(20-10)×60%×2=12(元),剩下的路程和燃油 附加费与没合乘时的价格是一样的,是一个固定值,因此合乘时,司机比正常营利18+12-20=10(元)。故选B。

The questions in this group are based on the content of a passage. After reading the passage, choose the best answer to each question. Answer all questions following the passage on the basis of what is stated or implied in the passage.

One of the best sources modem scholars have for learning about Hellenistic Egypt is the large supply of papyrus fragments that have turned up in the Egyptian desert over the last century. Papyrus is a thick type of paper made from a reedy plant found in Egypt. Papyrus is much tougher than the wood-pulp paper used in modern society; whereas a book produced today will most likely fall apart within a century, there are papyrus fragments that are still legible over 2,000 years after scribes wrote on them.

It is primarily by accident that any of these fragments have survived. Most of the surviving fragments have been found in ancient garbage dumps that were covered over by the desert and preserved in the dry heat. The benefit of this type of archeological find is that these discarded scraps often give us a more accurate picture of the daily lives of ancient Egyptians--their business affairs, personal correspondence, and religious pleas--than the stone engravings and recorded texts that were intended to be passed down to later generations.

One of the most important papyrus discoveries of recent years was the revelation in 2001 that a scrap of papyrus that had been discarded and used to wrap a mummy contained 110 previously unknown epigrams (short, witty poems) by the Hellenistic poet Posidippus (ca. 280-240 B.C.). Posidippus lived in Alexandria and benefited from the support of King Ptolemy II Philadelphos (ruled 284-246 B.C.). These new epigrams have yielded fascinating insight into the court culture and literary sensibilities of early Hellenistic Egypt.

King Ptolemy, of course, was also a sponsor of the famous library of Alexandria, the greatest depository of knowledge in the ancient world. According to the twelfth-century Byzantine writer John Tzetzes, the ancient library contained nearly half a million papyrus scrolls. If that library had not burned down, maybe archeologists today would not have to spend so much of their time sorting through ancient trash!

What does the author imply by the final statement: "If that library, had not burned down, maybe archeologists today would not have to spend so much of their time sorting through ancient trash!" ?()

A. The author implies that if the library had not burned down, archeologists would be able to appreciate the full cultural legacy of King Ptolemy Ⅱ Philadelphos.

B. The author implies that if the library had not burned down, scholars today would have not only the full works of Posidippus, but also those of Aeschylus, Sophocles, and Euripides.

C. The author implies that if the library had not burned down, the scrolls contained within the library would have decomposed before modern times in any event, because they would not have been preserved in the dry heat of the desert.

D. The author implies that if the library had not burned down, it might have contained more complete details about the life and culture of Hellenistic Egypt than can be found in the papyrus fragments from ancient refuse dumps.

E. The author implies that if the library had not burned down, the cultural awakening of the Renaissance might have occurred centuries earlier.
