六、阅读理解
Most people who move to a foreign country may experience a period of time when they feel very homesick and have a lot of worries. This feeling is often called “culture shock (冲击). It is important to understand it and learn what to do with it if you want to adapt to your new home’s culture successfully.
Generally speaking, there are four stages (阶段) that you will experience after you move to a foreign country. The first stage is usually called the “excitement” stage. When arriving in a new environment, you’ll be interested in the new culture. Everything will seem exciting and everyone will seem friendly.
But it won’t be long before you move from the “excitement” stage to the second stage. The excitement you felt before changes to worries. It seems that everything is difficult. The language is hard to learn, friends are difficult to make, and even simple things like shopping have become a difficult problem. It is at this “stress” stage that you may feel worried and homesick. This is the stage which is called “culture shock”.
However, culture shock doesn’t last for very long. If you are one of those who manage to get through it, you’ll move to the “recovery” stage. At this stage, you start to understand and accept the way things are done and the way people behave in your new environment.
The last stage is the “home” stage. This is the stage when you start to feel at home in the new culture. You start to learn from your new home and to like some ways of the new culture better.
Culture shock is common. Everyone in a new situation will go through it. Continue to be brave! And getting through culture shock will be a piece of cake.

3、NT 高三2025届普通高等学校招生全国统一考试模拟试卷(五)5数学答案


【答案】(1) Mg2+ MgSO4
(2) > BaSO4 Mg2+、Na+、K+ KCl 另取少许样品A加水配成溶液后，向溶液中加入过量硝酸钡，过滤后，滤液再加入硝酸银，若产生产生沉淀则含有氯化钾，反之则不含氯化钾。
【详解】（1）能与氢氧化钠反应产生白色沉淀的是Mg(NO3)2、MgSO4，故含有的金属阳离子是镁离子，符号为Mg2+；
能与氯化钡反应产生白色沉淀的是硫酸钠和硫酸镁，故溶液中含有的酸根离子是硫酸根，符号为；
由上述分析可知，溶液中含有的物质是硫酸镁，化学式为MgSO4；
（2）能与氢氧化钠反应产生气体的是硝酸铵，产生的气体是氨气，氨气的水溶液为氨水显碱性，pH>7；
步骤Ⅲ中加入硝酸钡，又加入了稀硝酸，产生了不溶于稀硝酸的沉淀则该物质的是硫酸钡，化学式为BaSO4；
