中国东北甲地区种植水稻原本以地表水灌溉为主,后来打井抽取地下水灌溉,发展“井灌种稻”。俄罗斯经济发展部建议将远东的几百万公顷土地(图中阴影所示区域)出租给外国投资者。我国投资者对此表现出极大兴趣。下图是俄罗斯远东局部区域示意图。

(1)地下水丰富成为甲地区发展“井灌种稻”的有利条件。请分析该条件的成因。(8分)

(2)甲地区沼泽广布。简要叙述甲地沼泽的形成原因。(8分)

(3)近年来中国人到乙地区租种土地现象不断增多,分析其社会经济原因。(6分)

答案

(1)河流、沼泽多;降水较多,蒸发较弱,土壤水分较多;植被条件较好,涵养水源能力较强;地势低平,排水不畅,下渗量大;土层中有冻土(答出4点即可,每点2分,共8分)

(2)位于三大河流交汇处附近,水量丰富;(2分)纬度高,气温低,地面蒸发弱;(2分)地势平坦,排水不畅;(2分)冻土不利于地表水下渗(2分)

(3)乙地区闲置土地面积较大;两国政策的支持;乙地区土地租金较低;农产品市场需求量大;中国临近乙地区;中国劳动力充足(答出5点即可,每点2分,共10分)

题目分析:

(1)从纬度看,这里大部分地区位于50°N-60°N之间,纬度高,气温低蒸发弱;从海陆位置看,东部临海,受海洋影响,降水较多,水量丰富;地势低平,河流较多,排水不畅,沼泽多;纬度高,地下有冻土层,土壤水分较多。人口少,植被破坏少,涵养水源能力强。

(2)甲地是我国三江平原地区,有三条大河交汇,水量丰富;平原地形,地势低平,排水不畅,下面有冻土层存在,地表水下渗少,易积水形成沼泽;这里纬度高,气温低,蒸发少,温带季风气候,受海洋影响,降水较多。

(3)俄罗斯地广人稀,闲置土地多,土地租金低,劳动力不足,我国劳动力丰富;俄罗斯纬度高,农业不发达,农产品市场需求量大。我国距乙地区近,种植方便。跨国作业,必须有两国政策的支持。

In America , driver’s education is part of the regular high school curriculum. Every student in his or her second year of high school is required to take a class in driver’s education. However, unlike other courses, it is not given during the regular school year. Instead it is a summer course.

The course is divided up into two parts: class time for learning laws and regulations and driving time to practice driving. Class time is not unlike any other class. The students have a text from which they study the basic laws they must know to pass the written driving test that is given to anyone wanting to get a driver’s license.

Driving time is a chance for the students to get behind the wheel(steering wheel) and practice starting steering, backing up, parking, switching lanes, turning corners, and all the other maneuvers (操作) required to drive a car. Each student is required to drive a total of six hours. The students are divided up into groups of four. The students and the instructor go out driving for two hour blocks of time. Thus, each student gets half an hour driving time per outing. The instructor and “driver” sit in the front seats and the other three students sit in the back.

Drivers ED cars are unlike other cars in which they have two sets of brakes, one on the driver’s side and one on the other side where the instructor sits. Thus , if the student driver should run into difficulties the instructor can take over. The car also has another special feature. On the top of the car is a sign that reads: STUDENT DRIVER. That lets nearby drivers know that they should use extra caution because the student driver is a beginning driver, not very experienced and prone to driving slowly.

After the student has passed the driver’s education course and reached the appropriate age to drive(this age differs in every state but in most cases the person must be 16 years old),they can go to a designated state office to take their driver’s test, which is made up of an eye examination, a written test, and a road test. The person must pass all three tests in order to be given a driver’s license. If the person did well in his or her driver’s education class, he or she will pass the test with flying colors and get a driver’s license.
