经济开发和环境保护的协调发展.
讲究实效,避免政绩工程、形象工程的泛滥.
在实施西部大开发中应特别注意保护生态环境.因为该地区自然环境条件较差,生态环境比较脆弱,一旦破坏,再想恢复会非常困难.

胡杨林变成木乃伊

我虽然会憎恨人类把我们抛弃在这里,但是,这也是我们树的命运,人类大量的砍伐树木,我在极乐世界等着别的树朋友的来到.

是经历并体验吧.

1.体会作者用词的精妙
（1）“胡杨树却益发向上,傲视身旁的沙丘”,这句话用了（拟人）的修辞手法,我从“傲视”这个词语体会到（胡杨树力争上游的坚贞品性）.
（2）“芨芨草、骆驼刺、旱芦苇、红柳树会相继前来投靠”中“投靠”在文中的意思是（生长,扎营,落脚等).
2.读一读文中画线的句子,再作答.
（1）这句话采用的修辞手法有（比喻和排比 ）.
（2）这句话把胡杨树分别比作（ 炬）、（ 伞 ）、（ 盖 ）、（ 云 ）等,从中我们感受到了（ 胡杨树的姿态各异 ）.
3.胡杨树的叶子幼时（细长如线）,年少如（柳叶 ）,壮年如（小扇）.作者从不同生长阶段写出了胡杨树叶子（形状）的不同.
4.写一句话来抒发自己对胡杨树的赞美之情,或者写写胡杨树给自己的启示.
启示：我们要像胡杨树一样,面对挫折顽强不屈,面对困难坚持不懈,对生活充满热情和毅力,用奋斗创造自己的多彩人生!

罗布泊过去是广阔、美丽、充满生机的湖泊,罗布泊周边是牛马成群、绿林环绕、河流清澈的生命绿洲.
现在变成了一片死寂的荒漠,胡杨林成片死亡,寸草不生,不见飞鸟,令人恐怖.
运用对比的手法来表达对仙湖消失的不舍

胡杨林最终因为缺水干枯了,枯萎后的独特身姿彰显自己的坚强与求助.

塔里木河水量减小,部分河道干涸,胡杨林渐渐枯萎,虽然号称“千年不死的胡杨”的美丽的树,注定渐渐枯死.如此一来,罗布泊没有水,便消失了.那一带,本就有沙漠,塔里木河、胡杨林、罗布泊会使沙漠化更严重,沙漠面积增大.
这是我自己的理解.

答案:D.
A项关联词搭配有误；B项缺失主语；C项唱出了后面应该搭配XX之情.

Bicycle ride of 110 kilometers
Hi everybody! After I took my college entrance examination in Qinghai, I was so eager, as well as my firends to find a way to have a good relaxation. We though a lot about the best way to do it. At the end We decided to visit a scenery called Huyanglin.
We gathered just after the dawn and set out for our bicycle trip.
Please take a look at this. What's funny about it is where you will see the smallest bike was ridden by the biggest guy. We were so worried that it was too small to take that much weight at first.However it turned out to be a bike of good quality.
As you might noticed the smallest bike got storage on its back and since none of rest bikes have something like this, It was the only one could be used to carry our stuffs.so when we did go ahead, I just wondered if it was too bad of us to do that. However soon after we were on the way, we were caught up with by two our classmates who came along by motorcycle. The small bike and its rider were then relieved from the burden of carrying all the bags.
Hulingyang is as far as 55 kilometers away from our city and it is windy all the year. Specially along the way to get there , we had been riding againt the wind and even up the hill. It was too hard for anyone like us who had never been riding in such long distance. So we had to take a rest in every few miles.
Later we figured out a better way to ride faster . But there was a consequence that the gasoline was about to run out. Fortunately a supplement of it in a bottle was send to us by the parent of a classmate who just need to take the same way in his trip to do some business.
By the time when we arrived there it was about noon, 6 hours after we started. We stopped at a suitable place for barbecue and then had coffee cooked by ourself using this gas stove as you can see in the pictures.
The beautiful scenery on the background of these photoes on the other hand seemed the most delightful pleasure I received. I bet you cannot tell how much I enjoyed by seeing the blue sky and white cloud when I looked up and with eyes full of green or caught by the filed of rape flowers when I turned my head a little down. The tireness of the long ride was just paid off by the refreshing feelings and the ease of mind.
It took us 4 hours to ride way back. When I arrived home, I was almost out of every bit energy I have to hold myself to stand.
When I recalled the journey of the 110 kilometer ride, thinking of my complains along the way about the distance and being exhausted, I was so proud that we finished it. What's more I learned about it is how important it is to hold on to the faith that we will be successed in whatever we do as long as we never give up.
