小题2:该地位于黄土高原地区,夏季多暴雨,水土流失严重,多滑坡和旱涝灾害,所以①④正确,故选D项。

小题3:该地貌顶面平坦,被沟谷分割,是黄土堆积在缓倾斜地面上的产物,为黄土梁地貌类型,为此需要植树造林种草,发展林果业和畜牧业生产,以保持水土,所以D正确。

小题4:黄土高原地区降水集中,且多为暴雨、黄土结构疏松,多孔隙、黄土中许多物质溶于水,都是造成黄土高原水土流失严重的自然因素,其人为因素是人类不合理活动,包括乱砍滥伐,过度开垦和放牧等。故选D项。

A.Decide to Be Happy
B.Lower Your Expectations
C.Learn to Enjoy the Moment
D. Look for the Good in Everything
E. Let People Deal with Their Own Problems
F. Focus More on What You Can Control Than on What You Can’t
So many times I hear people say that they will be happy once a certain event occurs. They think that once they move into a new house, start their new job, travel or retire they will be happy. But it doesn’t work that way.
If you truly want to be happy, here’s what to do.
1
 
You are not just a victim of circumstances or your emotions. Think about it this way. If you are in a horrible argument with someone, and the person you most respect enters the room, what will happen? The fighting will likely stop immediately, your mood will change, and so will your behavior. You do have control, and you are the one who decides how you will face the day!
2
 
We are never disappointed unless we have expectations. If you base your emotions on the need for certain things to happen, you will likely be let down most of the time. Instead, work hard, and treat everything good that happens as a bonus for which you can be thankful.
3
 
Don’t get too wrapped up in issues involving friends or family. We are each responsible for our own lives, and even when someone makes a bad mistake, it is not up to you to make things better. And remember that worry doesn’t help anyone!
4
 
You might not be satisfied with your income, but there’s no point complaining about it. Improve your diploma so that you can get a better job in the future. You may have an incurable illness, such as diabetes, but the fact that it’s incurable doesn’t mean that it cannot be managed.
5
 
   You don’t have to be a Pollyanna(盲目乐观者)about life, but you can see the bright side of almost every situation if you just make a point of looking for it. Happiness is not an uncatchable mouse! Once you have made up your mind that you are going to be happy despite what is going on around you, the task becomes easier. One of the key things to remember is that happiness doesn’t come from outside but begins on the inside and actually spread outward, and can influence everyone around you in a positive manner.
