题目内容
【题目】下表中为我国黑龙江、黄河、长江、珠江四条河流的水文特征。依据表中信息完成以下问题。
河流 | 长度(千米) | 有无结冰期 | 多年平均径流总量 (亿立方米) | 多年平均含沙量 (千克／立方米) |
① | 2215 | 无 | 3360 | 0.249 |
② | 3101 | 有 | 2709 | 0，16 |
③ | 5464 | 有 | 660 | 35 |
④ | 6300 | 无 | 9500 | 0.54 |
（1）四条河流中位于南方地区的是 ( )
A.①
B.②
C.③
D.④
（2）③河流含沙量大，该流域水土保持的措施是 ( )
A.植树种草
B.毁林开荒
C.增加放牧数量，提高收入
D.缓坡建梯田
【答案】
（1）A,D
（2）A,D
【解析】（1）以秦岭-淮河线为界，以南地区的河流主要流经湿润地区，水量丰富，汛期长，含沙量小，冬季河流不结冰；以北地区的河流主要流经半湿润或半干旱地区，水量不大，汛期较短，且冬季河流有结冰现象。可判定①④河流位于秦岭、淮河以南的南方地区。根据题意，故选：AD。（2）读表可知，③为黄河；黄河下游地上河部分经常泛滥决口；地上河的成因是黄河中游流经黄土高原，黄土高原土质疏松，植被破坏，土壤裸露，一遇暴雨，水土流失严重，使黄河的泥沙大增，下游又在华北平原上，河床宽坦，水流缓慢，泥沙大量淤积，使河床抬高形成，所以治理黄河的根本措施是在黄河中游植树种草、修筑梯田，搞好水土保持工作。根据题意，故选：AD。
【题目】读阅读下列短文, 根据短文中的信息完成文后表格。（每空一词）
Do you ever feel like you are just running from one activity to another? In school, do you rush from one subject to another?
When things happen so fast, it is easy to get lost of what you are doing or learning. It is important to stop yourself every now and then to think about what you've been doing or learning.
Self-reflection(反省) means slowing down and calming yourself, including calming your mind. By being calm and going slowly, you give your brain a chance to think about what it has already received. Some people prefer to do these self-reflections only in their mind. Others keep a diary or written notes. Either method works, depending on your own personal learning.
School textbooks are divided into units of study. This makes it easier for someone to begin self-reflection. Look for time when you complete a unit of study in the subjects you are learning, such as math, science and art. Sometimes you know the unit is over because there is some kind of test. Use these natural breaks to stop and do self-reflection.
Find a quiet place. You can even be sitting at your desk at school when you finish something early and the other students are still working. If you are going to take notes, take out paper or your reflection diary. Write down some notes on the new things that you learned in the unit. Let your mind think about the notes you have written and make some connections.
Next, think about things that you are not sure of. Maybe you learned a new way to work out a math problem, but you’re not sure when to use it. Writing down your questions will help you remember to look for answers the next time you are working with the same topic.
Self-reflection is important to a successful student. If you have never taken the time to do self-reflection, try it now.
