When the rate of inflation exceeds the rate of return on the most profitable investment available, the difference between those two rates will be the percentage by which, at a minimum, the value of any investment will decline. If in such a circumstance the value of a particular investment declines by more than that percentage, it must be true that______.

作家总是更容易接受环境保护的理论与实践。并非作家都懂多少环境保护的理论和知识，而是说作家毕竟更富有对于自然、对于祖国河山、对于一切生命的感受和热爱，作家对于生活的感受总是更富有整体感，作家相对的总是更少受某种实业目的的激励或者制约，作家更有可能多一点纯朴，也多一点浪漫。作家往往更早一点自觉或者不自觉的发出保护自然、保护环境的呼声，警报环境破坏的危险。如果我们阅读过契诃夫的《草原》，如果我们没有忘记《万尼亚舅舅》里那位医生对于生态破坏的忧虑，如果我们阅读过列昂诺夫的《俄罗斯森林》，如果我们哪怕是多看一眼邓刚的一系列为海洋和海洋生物呼天抢地的作品，我们会自然而然的变成一个更关心环境的人，变成一个与地球、宇宙、万物息息相关的人。如果我说作家天生应该与环境工作者携起手来，如果我说作家天然是环保工作者的同盟军，我想不至于被认为是过于冒昧。

我们似乎还可以从另外一个角度来谈论文学与环保。许多令人痛心的破坏环境的事情的发生，在我们这个国家里，并非由于采用了新技术新材料新制剂，而是由于人们文化素质之低下：放火烧荒，捕食珍惜野生动物，破坏草原，污染水源……的肇事者常常并不是化学工厂，恰恰是一些很普通的人，为了蝇头小利，竟可以做出破坏环境的大恶。提高人民的文化素质，当然是文学最为关心的事情，当然是作家、知识分子、干部深有切肤之痛的事情。

环境文学研究会的刊物《绿叶》终于和大家见面了，这是非常令人高兴的。……我们的刊物一定会得到文学工作者、环保工作者和广大读者的支持。

1、对“作家总是更容易接受环境保护的理论与实践”的原因说明不正确的一项是（   ）A、作家对于自然、对于祖国河山、对于一切生命的感受和热爱。

B、作家对于生活的感受总是更富有整体感

C、作家受某种实业目的的激励或者制约相对少一些。

D、作家往往更早一点自觉或者不自觉的发出保护自然、保护环境的呼声，警报环境破坏的危险。

2、“如果我们阅读过……呼天抢地的作品”想要说明的是（     ）

A、作家更容易接受环境保护的理论与实践。

B、作家自觉警报环境破坏的危险。

C、变成更关心环境的人的重要性。

D、创办刊物《绿叶》的重要性。

3、“我们似乎还可以从另外一个角度来谈论文学与环保”中“另一个角度”指：

A、许多令人痛心的破坏环境的事情的发生。

B、人们文化素质之低下。

C、文学最为关心的事情。

D、文学应为环保服务。

4、对文中信息推断不正确的一项是（     ）

A、读了文中列举的契诃夫等人的作品，“我们会自然而然的变成一个更关心环境的人”说明为了环境要多读以上著作。

B、   “作家相对的总是更少受某种实业目的的激励或者制约”是说作家唯实业为重而不顾环保的思想少一些。

C、   办好《绿叶》杂志就可更有效的加强人民群众保护环境的意识，因此，我们要关爱《绿叶》。

D、“作家天然是环保工作者的同盟军”是说作家理所当然也应该肩负起环境保护的重任。

Like all animal species, plant species must spread their offspring to suitable areas where they can grow and pass on their parents’ genes. Young animals generally spread by walking or flying. Because plants don’t have that ability, they must somehow hitchhike(搭车). Some plant seeds scatter by blowing in the wind or floating on water. Many other plant species, though, trick an animal into carrying their seeds. How do they do this? They enclose the seeds within a tasty fruit and advertise the fruit’s ripeness by its colour or smell. The hungry animal collects and swallows the fruit, walks or flies off, and later spits out the seeds somewhere far from its parent tree. Seeds can thereby be carried for thousands of miles. It may surprise you to learn that plant seeds can resist digestion. In fact, some seeds actually require passage through an animal’s body before they can grow.

Wild strawberries offer a good example of hitchhiking tactics. When strawberry seeds are still young and not yet ready to be planted, the surrounding fruit is green, sour and hard. When the seeds finally mature, the berries turn red, sweet, and tender. The change in the berries’ colour serves as a signal to birds which then eat the strawberries, fly off, and eventually spit out the seeds.

Naturally, strawberry plants didn’t set out with a conscious intention of attracting birds only when their seeds were ready to be dispersed. Nor did birds set out with the intent of planting strawberries. Rather, strawberry plants evolved through natural selection. The sweeter and redder the final strawberry, the more birds spread its ripe seeds; the greener and more sour the young strawberry, the fewer birds destroyed the seeds by eating berries before the seeds were ready.
