【題目】下列關(guān)于我國人口與民族、地理差異的說法，正確的是

A.我國人口主要分布在西部和中部

B.漢族均勻分布于全國各地

C.我國北方地區(qū)的大部分地區(qū)屬于半濕潤地區(qū)

D.我國西部地區(qū)，氣候干旱，降水稀少，只發(fā)展畜牧業(yè)

【答案】C

【解析】

中國人口地區(qū)分布不均。一般來說，以黑河—騰沖線為界，東南部地區(qū)人口多(稠密)，西北部地區(qū)人口少(稀疏)。故A錯誤。漢族分布最廣，主要集中在東部和中部地區(qū)，少數(shù)民族則主要分布在西南、西北和東北部地區(qū)，B錯誤。我國秦嶺—淮河一線是我國800mm等降水量和南北方地區(qū)的分界線，該線以南是南方地區(qū)屬于濕潤區(qū)，以北是北方地區(qū)大部分屬于半濕潤區(qū)，故C正確。我國西北地區(qū)利用高山的冰雪融水發(fā)展綠洲農(nóng)業(yè)，D錯誤。故選C。

【題目】讀閱讀下列短文, 根據(jù)短文中的信息完成文后表格。（每空一詞）
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.
