【题目】下列关于我国人口与民族、地理差异的说法,正确的是

A.我国人口主要分布在西部和中部

B.汉族均匀分布于全国各地

C.我国北方地区的大部分地区属于半湿润地区

D.我国西部地区,气候干旱,降水稀少,只发展畜牧业

【答案】C

【解析】

中国人口地区分布不均。一般来说,以黑河—腾冲线为界,东南部地区人口多(稠密),西北部地区人口少(稀疏)。故A错误。汉族分布最广,主要集中在东部和中部地区,少数民族则主要分布在西南、西北和东北部地区,B错误。我国秦岭—淮河一线是我国800mm等降水量和南北方地区的分界线,该线以南是南方地区属于湿润区,以北是北方地区大部分属于半湿润区,故C正确。我国西北地区利用高山的冰雪融水发展绿洲农业,D错误。故选C

【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.
