问题 综合

(10分)读我国华北地区等高线地形图(单位:米)和西北局部地区年降水量(单位:毫米)图,其中A河河谷被称为我国的“西域湿岛”。完成下列问题。

   

(1)说出左图中甲区的地貌类型,并简述其形成过程。(3分)

(2)左图中乙地区是我国环境问题严重的地区之一,说出其环境问题,并分析产生的主要自然原因。(4分)

(3)分析A河谷地成为“西域湿岛”的原因。(3分)

答案

(1)冲积扇(1分)①当上游水流流出山口时,由于地势突然趋于平缓。(1分)②水流速度减慢,河流搬运的物质逐渐在山麓地带堆积下来,形成扇状堆积地貌。(1分)

(2)水土流失(1分) 原因①降水多而集中,多暴雨;(1分)②黄土疏松,容易被冲刷、侵蚀;(1分)③植被覆盖率低。(1分)

(3)①伊犁河谷属于向西(呈喇叭口形)敞开的地形,来自大西洋的暖湿气流容易聚集;(1分)②受地形抬升,形成山地降水;(1分)③河谷地区,汇集了山地降雨和高山冰雪融水,地表水比较丰富;(1分)④河谷绿洲,蒸发水汽较多,水循环相对活跃,(1分)从而成为“西域湿岛”等。(只需要回答三点得3分)

题目分析:

(1)读图,根据经纬度可以判断,甲区域是太行山的山麓冲积扇。当上游水流流出太行山山口时,由于地势突然趋于平缓,水流速度减慢。河流搬运的物质逐渐在山麓地带堆积下来,形成扇状堆积地貌。

(2)读图,乙地区位于黄土高原,夏季降水多而集中,且多暴雨。黄土疏松,容易被冲刷、侵蚀。黄土高原地区的植被覆盖率低。所以该地主要生态环境问题是水土流失。

(3)根据经纬度判断,A河谷地是伊犁河谷,属于向西呈喇叭口形敞开的地形,来自大西洋的暖湿气流容易聚集。在这里受天山山脉地形的强烈抬升,形成山地降水。河谷地区,汇集了山地降雨和高山冰雪融水,地表水比较丰富。河谷绿洲发育,蒸发水汽较多,水循环相对活跃,从而成为“西域湿岛”等。

(D)

Hunting for a job is a painful experience, which nearly everyone must endure at least once in a lifetime. Books are published and magazine articles are written on the subject, all trying to tell job seekers what they should do or avoid in order to win the game. They can’t calm the nervous applicant but they do offer some advice.

To begin with, it is not a good idea to be late. Job interviewers don’t think very highly of the candidate(应聘者)who arrives twenty minutes after the appointed time . The wise job seeker explores the place the day before. Next day he arrives early for the appointment.

What makes a good impression? Being on time does, then, appearance. It is essential for the candidate to be dressed properly and to look alive. It is also very important to look the interviewer in the eye because this “eye contact” gives a strong impression of sincerity and openness.

Many candidates waste a good part of the interview explaining why they want the job; the man or the woman on the other side of the desk is waiting to hear why the would-be employee would be good for the position and for the company.

It is a very difficult task to display oneself to possible employer: one must not be too humble, since it is essential to show one’s good points and experiences. However, bragging(说大话)doesn’t make a very good impression. One thing is certain: interview time is a time for honesty. The interviewer is trying to discover not only the professional worth but also the character of the man or the woman he is meeting. Therefore, he must rely on his observation of the applicant, her manners, what she says and how she says it.

While this examination is going on, the job seeker should remember that she too has a right to be curious. It is recommended that the applicant ask some serious questions about the job, the company, and its future. If the questions are intelligent, they will impress the interviewer favorably.
