选择b 就是问哪个地区可以承受最大的人类对环境的压力,显然是环境条件最好的珠三角地区.
环境承载力又称环境承受力或环境忍耐力.它是指在某一时期,某种环境状态下,某一区域环境对人类社会、经济活动的支持能力的限度.人类赖以生存和发展的环境是一个大系统,它既为人类活动提供空间和载体,又为人类活动提供资源并容纳废弃物.

暂时想到这么多,再给你想想

此处共有两种方法,我现在这里说一种,楼主若是真有体会可自行明白第二种并无需我多说,这是考研时候复习的一点小心得,发现大量的课本教材都回避了这个问题,不知道到底是为了什么.
方法：类似于方差已知,估计期望的那个标准正态分布枢轴,然后将其平方,就可以得到一个卡方（1）分布,选择上（a/2）与上（1-a/2）两个分位数即可得到1-a的置信区间.这时候枢轴的分母是方差,避开了用标准正态分布枢轴求解不等式时的麻烦,可以得到结果.

用待定系数法
一次函数的通式为：f(x)=ax+b
将A代入代数式可得b=-1,得f(x)=ax-1
再将B代入代数式可得a=2/3
所以f(x)=(2x/3)-1

Dear Green,
I was glad of receiving your letter. Thank you for your asking! I agree with your opinion.
There are three columns, which I like, I want to mention. The first one is News. From it, we can introduce the incidents in school or out school. The second one is Teachers"Advice. Students can receive teachers' advise through this column. The last one is Students"Voice. It makes that students' opinion and emotion can be heard.
Best wishes!
Sincerely yours,

A Spring Outing
Spring came with all its glories. The new grass exposed its green colour. The pretty flowers opened their blossoms.We were tempted to go for an outing.
It was Sunday, the 20th of April. We set out very early on bikes, carrying bottles of champagne, beer and bags of cakes, bacon and cooked eggs. We rode along the winding paths in the fields, across the meadows and down the roads.The willow were fresh and green. The swallows were flying to and fro, up and down the sky. The birds, like musicians,snang their melodious songs in the trees, and the butterflies,like colorful dancers, were fluttering here and there. We breathed the fresh air deeply and laughed heartily.
At 10 a.m. we arrived at the foot of the $hushan Hill.We left our bikes with a bike-repairing shop and began to climb up the Hill. Near the top, under a big tree with luxuriant foliage we had our picnic. We drank and ate, talked and laughed. After the picnic we stood in the breeze with our hands on our waists, enjoying the fine landscape. Then we lay on the grass talking about our life and studies.
At about 4 p. m. , we returned with balmy greenness on our backs and freshness in our hearts

开始之前,把食谱（翻译为食谱或配方,看你上下文的意思）整个读一遍,把需要用的原料和器具准备齐全.如果你用完一样原料就收起来放好,那制作过程中被打断的话也很容易就知道哪一样原料你已经加完了.

不要干扰虫茧.一旦昆虫结茧,那我们就没什么需要做的了.最好让每个人都知道,别去碰虫茧,因为蝴蝶正在里面“成型”,如果有人去干扰它,那么它可能不能正常地成长.这是一个培养孩子们耐心的好机会.

敲4下有三个间隔 每个间隔=12/3=4秒
敲5下有四个间隔则4X4=16秒

首先,最重要的,你要对这门学科有兴趣.
其次,英语当中,词汇量是基础,一定要有一定量的词汇积累.至于方法,你可以背你们英语教材课后的单词,或者,选择在生活当中做有心人,多关心生活当中的英语,比如广告,生活用品说明书之类的.
最后,在有了一定的词汇积累之后,可以到书店买一些练习题来做,主要是在做题过程中了解一些出题规律和答题技巧,并且培养自己的做题节奏.
一点愚见,希望能够帮助到你.
