Only minutes after the probes hit the ground, the lander will follow, descending by parachute and braking engine. Bristling with cameras and sensors, it will study Mars' terrain and weather, snapping pictures both during its descent and on the surface. It will also carry a microphone to record for the first time the sound of the Martain wind. More important, the ship will be equipped with a robotic arm and scoop , much like the arms carried aboard the Viking landers in the 1970s. Unlike the Vikings, though, which were able to paw just a few feeble cm into the Martian topsoil, the new ship will dig out a trench nearly 90 cm deep. ={xE!
"
How long all this otherworldly hardware will operate is uncertain. The probes, powered by batteries, should wink out within three days. The lander, with robust solar panels to keep it humming, could last three months. But even if the systems do not survive that long, their work could be profound. After all, scientists have spent years studying just the Martian skin; this will be their first chance to dig a little deeper. m-*hygkcDu

Passage Four oPXkYW
An outsider approaches the subject lively, lest civic(市民的;城市的) feelings be bruised. Los Angeles gives the impression of having erased much of its history by allowing the city's development to run unchecked. Insiders like Dolores Hayden...pull no punches: "It is...common," she wrote, "for fond residents to quote Gertrude Stein's sentence about Oakland when summing up urban design in Los Angeles: "There's no there, there.'" Hayden has also acknowledged that Los Angles is generally "the first (American city) singled out as having a problem about sense of place." Both statements come from a handsome brochure-cum-itinerary, drawn up by Hayden, Gail Dubrow, and Carolyn Flynn to introduce The Power of Place, a local nonprofit group with a mission to retrieve some of the city's misplaced" there." JNt^ (z
Founded by Hayden in 1982, The Power of Place lays special emphasis on redressing an imbalance in memory---and memorials. As Hayden has pointed out, in 1987 less than half the population of Los Angeles was Anglo-American; yet almost 98 percent of the city's cultural historic landmarks were devoted to the history and accomplishments of Anglo-Americans. Even these personages(名人,要人) come from a narrow spectrum of achievers---in Hayden's phrase, "a small minority of landholders, bankers, business leaders, and their architects" ----almost all of whom were male... ->y J5smtY
The likeliest explanation for this under-representation may be an urban variation on the great-man theory of history: History is what public figures do, and by their civic monuments shall you know them ---especially the structures they designed or built. In Hayden's view, however, "The task of choosing a past for Los Angeles is a political as well as historic and cultural one, " and the unexamined preference for architecture as the focus of historic preservation efforts can slight less conscious but perhaps equally powerful human forces. Hayden's goal has been to supplement the city's ample supply of mono-cultural landmarks and memorials with others representing its ethnic and gender-based diversity. Accordingly, some sites need new status as official land-marks, others need reinterpretation. Other sites no longer contain structures emblematic(作为标志的) of their histories or are located in blighted neighborhoods; these do not readily lend themselves to resuscitation (复兴)through renovation and commercial development , as preservationists have managed elsewhere.
`lO[x.[
The Power of Place has identified nine places on which to concentrate in the first phase of its work: development of a walking tour of little-known Los Angeles sites, for which The Power of Place brochure serves as a guide. HUv/ ~^<
The Power of Place brochure concludes its summary of what is known about each stop on the walking tour with a postscript(附言)called Placemaking, which describes the site's current status and suggests ways to make it more smelling of its past. For the vineyard/grove complex, the current situation is not unusual: "Present uses...are commercial and industrial." Then comes word of what seems to be a minor miracle: "One tall slender grapefruit free...has been preserved and relocated in the courtyard of the Japanese American Cultural and Community Center..." Suggestions for recapturing more of the past proposed by The Power of Place include returning orange trees to the Wolfskill site and installing historical markets on the Vignes site. a1t4Dd

Passage Five @6{~05.p
Compared to animals, plants present unique problems in demographic studies. The idea of counting living individuals becomes difficult given perennials that reproduce vegetatively by sending out runners or rhizomes, by splitting at the stem base, or by producing arching canes that take root where they touch the ground. In these ways some individuals, given sufficient time, can extend out over a vast area. AvdXEY(-
There are five typical plant life spans, and each has a basic associated life form. Annual plants live for 1 year or less. Their average life span is 1-8 months, depending on the species and on the environment where they are located (the same desert plant may complete its life cycle in 8 months one year, and in 1 month the next, depending on the amount of rain it receives). Annuals with extremely short life cycles are classified as ephemeral plants. An example of an ephemeral is Boerrhaviarepens of the Sahara Desert, which can go from seed to seed in just 10 days. Annuals are herbaceous, which means that they lack a secondary meristem that produces lateral, woody tissue. They complete their life cycle after seed production for several reasons: nutrient depletion, hormone changes, or inability of nonwoody tissue to withstand unfavorable environmental conditions following the growing season. A few species can persist for more than a year in uncommonly favorable conditions. G?EoPh^m
Biennial plants are also herbaceous, but usually live for 2 years. Their first year is spent in vegetative growth, which generally takes place more below ground than above. Reproduction occurs in the second year, and this is followed by the completion of the life cycle. Under poor growing conditions, or by experimental manipulation, the vegetative stage can be drawn out for more than 1 year. u+'tfFds&
Herbaceous perennials typically live for 20-30years, although some species have been known to live for 400-800 years. These plants die back to the root system and root crown at the end of each growing season. The root system becomes woody, but the above-ground system is herbaceous. They have a juvenile, vegetative stage for the first 2-8 years, then bloom and reproduce yearly. Sometimes they bloom only once at the conclusion of their life cycle. Because herbaceous perennials have no growth rings, it is difficult to age them. Methods that have been used to age them include counting leaf scars or estimating the rate of spread in tussock (clumped) forms. 1QLbf*zeIW
Suffrutescent shrubs (hemixyles) fall somewhere between herbaceous perennials and true shrubs. They develop perennial, woody tissue only near the base of their stems; the rest of the shoots system is herbaceous and dies back each year. They are small, and are short-lived compared to true shrubs. h3bff#<K
Woody perennials (trees and shrubs) have the longest life spans. Shrubs live on the average 30-50 years. Broadleaf trees (angiosperm) average 200-300 years, and conifer (needles) trees average 500-1000 years. Woody perennials spend approximately the first 10% of their life span in a juvenile, totally vegetative state before they enter a combined reproductive and vegetative state, achieving a peak of reproduction several years before the conclusion of their life cycle. Min
^>
Regardless of the life span, annual or perennial, one can identify about eight important age states in an individual plant or population. They are: (1) viable seed, (2) seedling, (3) juvenile, (4) immature, (5) mature, (6) initial reproductive, (7) maximum vigor (reproductive and vegetative), and (8) senescent. If a population shows all eight states, it is stable and is most likely a part of a climax community. If it shows only the last four states, it may not maintain itself and may be part of a seral community. n` xR5!de

">y%iE
In the eighteenth century the word "revolution" came to have a new meaning. Traditionally it meant only a change in the composition of government and not necessarily a violent one. Observers could speak of a "revolution" occurring at a particular court when one minister replaced another. After 1789 this changed. People came to see that year as the beginning of a new sort of revolution, a real rupture with the past, characterized by violence, by limitless possibilities for fundamental change, social, political and economic, and began to think, too, that this new phenomenon might transcend national boundaries and have something universal and general about it. Even those who disagreed very much about the desirability of such a revolution could none the less agree that this new sort of revolution existed and that it was fundamental to the politics of their age. ha(Z<
It would be misleading to seek to group all the political changes of this period under the rubric of "revolution" conceived in such terms as these . But we can usefully speak of an "age of revolution" for two reasons. 9J9)AV
