问题 单项选择题

煤炭是世界储量最丰富的化石燃料,其储量在世界能源总储量中占90%,按目前规模开采可持续200年左右。据上个世纪80年代初世界能源会议等组织的资料,世界煤资源的探明储量为3.5万亿吨,约占总地质储量的24.5%。煤炭的种类可分为硬煤、褐煤和泥煤等。泥煤的数量相对较少,硬煤占总储量的74.2%,褐煤占23.7%。据统计,拥有煤炭资源的国家大约有70个左右,其中储量较多的国家有中国、俄罗斯、美国、德国、英国、澳大利亚、加拿大、印度、波兰和南非地区。
我国的煤炭资源预测地质储量,达45000亿吨以上,但能作为规划设计的实际依据的探明储量,特别是可供建井用的精查储量却很低,累计探明储量超过7000亿吨,其中精查储量为17.5亿吨。山西省的煤炭储量2000多亿吨居全国第一,内蒙古居第二位。煤炭储量超过200亿吨的省、自治区有陕西、贵州、宁夏、安徽等。

下列表述不正确的是( )。

A.按目前规模开采,全世界的煤炭还可以使用200年左右

B.全世界煤炭总储量为14.3万亿吨

C.我国可供建井用的精查煤炭储量不容乐观

D.我国煤炭储量最高的省份的简称是冀

答案

参考答案:D

解析: 通过阅读第一段的第一句话,可知A选项正确,通过计算可知世界煤炭资源总储量为14.3(万亿吨),故B选项正确。文中表述中写道“……可供建井用的精查储量却很低……”,因此情况不容乐观,故C项也正确。D项中,我国煤炭储量最高的省份是山西省,山西省的简称为“晋”,而不是“冀”,故错误。本题正确答案为D。

As they went    22    , they saw lying in the path a pair of old    23    , which they supposed to belong to a poor man who was employed in a   24   close by. The student turned to the professor, saying, “Let’s play the man a   25  : We will hide his shoes, and 26   ourselves behind those bushes, and wait to see his   27  when he cannot find them.”
“My young friend,” answered the professor, “we should never   28   ourselves at the   29   of the poor. But you are   30  , and may give yourself a much greater   31  by means of the poor man.

He now put the money into his pocket, but his  38  was doubled on finding the other coin. He fell upon his knees, looked up to heaven and uttered aloud a fervent(热烈的)thanksgiving, in which he   39  his wife, sick and helpless, and his children without bread. The student stood there deeply   40 , and his eyes filled with tears.
