One of these pioneer ecologists was Frederick Clements, who studied ecology extensively th

roughout the Midwest and other areas in North America. He held that within any given region of climate, ecological communities tended to slowly converge toward a single endpoint, which he called the "climatic climax." This "climax" community was, in Clementss mind, the most well-balanced, integrated grouping of species that could occur within that particular region. Clements even thought that the process of ecological succession—the replacement of some species by others over time—was somewhat akin to the development of an organism, from embryo to adult. Clements thought that succession represented discrete stages in the development of the community(rather like infancy, childhood, and adolescence), terminating in the climatic "adult" stage, when the community became self-reproducing and succession ceased. Clementss view of the ecological community reflected the notion of a precise balance of nature.

In paragraph 5, why does the author mention green ash trees and plains cottonwood trees？

A．To support the current view about how ecological communities develop

B．To provide an example of species that prefer to live on floodplains

C．To provide evidence that supports the theory of Clements

D．To show where one ecological community stops and the other begins

第5题

Someday a stranger will read your e-mail without your permission or scan the Websites you'

ve visited. Or perhaps someone will casually glance through your credit card purchases or cell phone bills to find out your shopping preferences or calling habits.

In fact, it's likely some of these things have already happened to you. Who would watch you without your permission？ It might be a spouse, a girlfriend, a marketing company, a boss, a cop or a criminal. Whoever it is, they will see you in a way you never intended to be seen — the 21st century equivalent of being caught naked.

Psychologists tell us boundaries are healthy, that it's important to reveal yourself to friends, family and lovers in stages, at appropriate times. But few boundaries remain. The digital bread crumbs(碎屑) you leave everywhere make it easy for strangers to reconstruct who you are, where you are and what you like. In some cases, a simple Google search can reveal what you think. Like it or not, increasingly we live in a world where you simply cannot keep a secret.

The key question is: Does that matter？

For many Americans, the answer apparently is "no."

When opinion polls ask Americans about privacy, most say they are concerned about losing it. A survey found an overwhelming pessimism about privacy, with 60 percent of respondents saying they feel their privacy is "slipping away, and that bothers me."

But people say one thing and do another. Only a tiny fraction of Americans change any behaviors in an effort to preserve their privacy. Few people turn down a discount at tollbooths(收费站) to avoid using the EZ-Pass system that can track automobile movements. And few turn down supermarket loyalty cards. Privacy economist Alessandro Acquisti has run a series of tests that reveal people will surrender personal information like Social Security numbers just to get their hands on a pitiful 50- cents- off coupon (优惠卷).

But privacy does matter — at least sometimes. It's like health: When you have it, you don't notice it. Only when it's gone do you wish you'd done more to protect it.

What does the author mean by saying "the 21st century equivalent of being caught naked" (Lines 3-4, Paragraph 2 ) ？

A．People's personal information is easily accessed without their knowledge.

B．In the 21st century people try every means to look into others' secrets.

C．People tend to be more frank with each other in the information age.

D．Criminals are easily caught on the spot with advanced technology.

第9题

Everyone of us lives and works on a small part of the earth's surface, moves in a small ci

rcle, and of these acquaintances knows only a few intimately. Of any public event that has wide effects we see at best only a phase and an aspect. This is true that the eminent insiders, who draft treaties, make laws, and issue orders, are like those who have treaties framed on them, laws promulgated to them, orders given at them. Inevitably our opinions cover a bigger space, a longer reach of time, many things, that we can directly observe. So they have to be pieced together out of what others have reported and what we can imagine. Yet even the eyewitness does not bring back a naive picture of the scene. For experience seems to show that he himself brings something to the scene which later he takes away from it, that oftener than not what he imagines to be the account of an event is really a transfiguration of it. Few facts in consciousness seem to be merely given. Most facts in consciousness seem to be partly made. A report is the joint product of the knower and known, in which the role of the observer is always selective and usually creative. The facts we see depend on where we are placed, and the habits of our eyes.

The limited time and space which man occupies suggest, according to the paragraph,

A．man's life is also insignificant.

B．man's opinions can not be accurate at all.

C．human observations in general are all but partial.

D．man cannot have any opinion.
