山脉常常成为我国省级行政区的天然分界线。下列对四幅图中山脉名称的判断正确的是:

A.①太行山脉 ②武夷山脉 ③昆仑山脉 ④祁连山脉

B.①大兴安岭 ②台湾山脉 ③天山山脉 ④阿尔泰山脉

C.①雪峰山脉 ②长白山脉 ③秦岭山脉 ④大别山脉

D.①巫山山脉 ②武夷山脉 ③阴山山脉 ④横断山脉

答案

答案:A

题目分析:山西省和河北省的天然分界线是太行山脉,江西省和福建省的天然分界线是武夷山脉,新疆维吾尔自治区和西藏自治区的天然分界线是昆仑山脉,甘肃省和青海省的天然分界线是祁连山脉。所以本题选择A选项。

点评:我国东北-西南走向的山脉,自西向东分为三列:西侧一列包括大兴安岭、太行山、巫山、雪峰山等;中间一列包括长白山、武夷山等;最东的一列是台湾岛上的台湾山脉。我国东西走向的山脉主要有三列:靠北的一列是天山、阴山;中间的一列是昆仑山和秦岭;靠南的一列是南岭。山脉构成我国地形的骨架,有些山脉还是地形区的分界线,如:太行山东侧是华北平原,西侧是黄土高原;昆仑山北侧是塔里木盆地,南侧是青藏高原。

To Chinese immigrants, in the mid-1800s, California was “The Land of the Golden Mountain.” In their homeland they had heard the words, “There’s gold in California.” They sailed 7,000miles to join the gold rush and strike it rich. Between 1849 and 1882, more than 30,000 Chinese came to California. Most were men. They had been farmers in China. They came here to be miners and laborers. They ended up doing many other jobs, too.

Like many other immigrants, they did not plan to stay in America. They came because of their ties to their homeland and their families. They planned to return to China with their fortunes and help their families.

Only a few Chinese gold miners struck it rich. Most picked over the areas that had been mined already. But still, white miners resented the Chinese. Slowly, they drove the “yellow peril” from the mining camps.

By the end of the 1850s, many Chinese returned home. Those who stayed found other jobs.

Few women had come west in the gold rush. The Chinese saw a good business opportunity. They began doing the jobs women would have done. Many became house servants. Many more opened  laundries.

The Chinese opened restaurants. Chop suey and show mein are popular Chinese-American dishes. The Chinese probably created these dishes to serve to the white miners.

Other Chinese became fishermen, farmers, and even cigar makers.

1. Why did Chinese go to America in the mid-1800s?

A. Because they could find good jobs there.   B. Because they had found gold there.

C. Because they could open laundries and restaurants there.

2. The underlined word “resented” mean “________”.  

A. liked                        B. helped               C. hated                    D. served

3. Which should be the title of the passage?

A. Early Chinese immigrants in America     B. Dream to strike it rich

C. The difference between men and women   D. Gold miners in America

1996年1月24日11时25分,A市矿务局某煤矿多种经营公司的下属煤矿之一的七井发生一起特别重大的瓦斯爆炸事故,死亡人数达到99人(其中女职工37人)、伤3人,直接经济损失450万元。该矿直属于B集团公司。
七井曾在1994年和1995年连续两年被B集团公司多种经营公司授予A级质量标准化井。施工七井与六井相贯通的西主运巷,属于后来的技术改造工程,没有科学的设计和规划,煤矿多种经营公司把此项工程仅作为一般掘进巷道对待。局多种经营公司对该项工程没有引起足够的重视,只是口头同意,没有制定贯通后相应可靠的隔爆等安全措施。
1月24日早晨6时30分,七井井长刘某、生产副井长李某分别召开七井、六井班前会。会议宣布了煤矿多种经营公司22日的会议决定,25日各井停产放假一天,并对该天的工作做出统一安排和部署,对所属各段队当班的工作做出了相应的安排布置。8时左右,七井煤矿87人,六井煤矿24人分别入井工作。
当天正值公司对各井进行月末验收工作,七井主任兼工程师黄某和七井各段段长与公司地测科主测王某等4名测工入井作业,并对左三、右四、右二工程工作面进行检测和验收。
七井在九点时停电,七井的左三工作面风电闭锁装置,由于发生了故障已于1月22日拆除,至24日仍未能及时更换安装。井下停电停风,引起瓦斯积聚。
停电之后,工人仍在井下工作。到11时25分时,在左三工作面,放炮员正在进行放炮作业,其他人员处于躲炮位置。因放炮员违章使用煤电钻电源插销,明火放炮产生火花,引起瓦斯爆炸。
在99名遇难者中,七井遇难人员多被爆炸的冲击力而致死,而六井的遇难人员均为一氧化碳中毒,冲击伤并不明显。
当天,七井主任工程师黄某和七井各段段长与公司地测主测王某等4名测工对左三、右四、右二工程工作面地质变化和瓦斯量增加未予引起足够的重视,当即验收了左三、右四、右二工程,并于11时许升井。刚升井就听到井筒传出巨大的轰响声,爆炸发生了。
事故发生之后,七井制定了工作面停风撤人和瓦斯排放制度,瓦斯巡视员对巡视路线、巡视点和检测时间记录不清,入井人员没有配备自救器;井下没有隔爆设施和消尘洒水系统;特种作业人员(瓦斯检查工、放炮工等)未按规定培训考核和持证上岗;对女职工入井作业问题,矿务局始终没有彻底查除。
