一般而言,单位土地面积上植物的叶片总面积越大,生长速度和蒸腾量越大。在我国的一些干旱和半干旱地区,50多年来,年年植树,但因成活率低,目前森林覆盖率不到1%。

(1 )干旱半干旱地区的自然植被是                  和荒漠。

(2 )在干旱、半干旱地区进行生态建设,如果有①植树造林、②种草、③自然恢复三种措施,你倾向于哪一种?请说明理由。

答案

(1)草原(1分)

(2)选②或③。(2分)理由:该区域自然植被为草原和荒漠,(1分)森林生态耗水量远大于草原(森林单位土地面积上的叶片总面积与生长速度大于草本植物),过量植树,会加重区域旱情。(1分)种草或自然恢复,较植树造林更符合自然规律,且投入较少。(1分)

本题考查区域环境的综合分析。干旱地区,水源不足,故主要的自然植被为草原和荒漠。(2)干旱、半干旱地区,水资源不足,故植树造林消耗的水量大,且树木成活率不高,不故适宜。而从该地区的自然环境考虑,该地区的自然植被为草原和荒漠,故应以种草和自然恢复为主。

We can make mistakes at any age.Some mistakes we make are about money.But most mistakes are about people.One might say, "Did Jerry really care when I broke up with Helen?" "When I got that great job, did Jim really feel good about it, as a friend? Or did he envy my luck?" When we look back, doubts like these can make us feel bad.

Why do we go wrong about our friends? Sometimes what people want to say hides their real meaning.And if we don't really listen, we miss the feeling behind the words. Suppose someone tells you, "You're a lucky dog." Is he really on your side? If he says, "You are a lucky guy", that's being friendly.But if he says "a lucky dog", there's a bit of envy in those words.Maybe he doesn't see it himself.But he puts you down a little if he brings in the "dog".What he may be saying is that he doesn't think you deserve your luck.

"Just think of all the things you have to be thankful for" is another noise that says one thing and means another.It could mean that the speaker is trying to get you to see your problem as part of your life as a whole.But is he trying to? Wrapped up in this phrase is the thought that your problem isn't important.It's telling you to think of all the starving people in the world when you haven't got a date for Saturday night.

How can you tell the real meaning behind someone's words? One way is to take a good look at the person talking.Do his words fit the way he looks? Does what he says agree with the tone of voice, his posture, or the look in his eyes? Stop and think.The minute you spend thinking about the real meaning of what people say to you may save another mistake.

Therefore, when you hear someone saying, please try to know what he really means.Don't just listen to what he says with your ears but feel the words he uses with your head.In this way you may make fewer mistakes.
