Wich the decision, Bush takes the first step foward fulfilling a campaign pledge to developand deploy an anti-missile system that he says will protect the United States and its allies,including Russia, from missiles fired by hostile nations.

　　Russia and many US allies have warned Bush that withdrawing from the pact might trigger anuclear arms race. Critics of the plan also question whether an effective system can bedeveloped without enormous expense.

　　The president defended his push for a missile shield during a national security speechTuesday at the Citadel in South Carolina.

　　"Last week we conducted another promising test of our missile defense technology," Bushsaid. "For the good of peace, we're moving forward with an active program to determine whatworks and what does not work. In order to do so, we must move beyond the 1972 Anti-BallisticMissile Treaty, a treaty that was written ina different era, for a different enemy."

　　"America and our allies must not be bound to the past. We must be able to build the defenseswe need against the enemies of the 2lst century," he said.

　　According to Bush administration officials, Russian President Vladimir Putin had assured Bushduring theirOctober talks in Washington that US-Russian relations would not suffer even ifBush pulled out of the treaty.

　　The decision came as Secretary of State Colin Powell, in Moscow, said Russia and the UnitedStates are near agreement on drastic cuts in long-range nuclear arsenals, but remain, at oddsover a US missile defense.

　　美國(guó)政府官員星期二宣稱，美國(guó)總統(tǒng)布什不久將會(huì)通告俄羅斯，[l]美國(guó)將要退出1972年簽署的禁止測(cè)試導(dǎo)彈防御系統(tǒng)的核控制條約。

　　布什總統(tǒng)將會(huì)在隨后的幾天中宣布這一決定。[2]該決定是基于《反彈道導(dǎo)彈條約》中的一個(gè)條款，即美國(guó)和俄羅斯若要放棄該條約。都必須提前6個(gè)月通知對(duì)方。

　　這一決定是布什總統(tǒng)為履行其發(fā)展并部署反導(dǎo)彈系統(tǒng)的競(jìng)選承諾而邁出的第一步。他說(shuō)，這個(gè)系統(tǒng)可以保護(hù)美國(guó)及其盟國(guó)(包括餓羅斯)免受敵對(duì)國(guó)家發(fā)射的導(dǎo)彈攻擊。

　　[3]俄羅斯和美國(guó)的許多盟國(guó)都曾警告布什，退出該條約有可能引發(fā)核武競(jìng)賽。批評(píng)這個(gè)計(jì)劃的人還懷疑，如果不投入巨大的開(kāi)支是否有可能開(kāi)發(fā)出一個(gè)有效的反彈道系統(tǒng)。

　　星期二在南卡羅萊納州大本營(yíng)舉行的一場(chǎng)有關(guān)國(guó)際安全的演講中，布什總統(tǒng)為自己推行導(dǎo)彈防御做出了辯護(hù)。

　　布什說(shuō)：“上周我們又成功進(jìn)行了一次對(duì)導(dǎo)彈防御技術(shù)的試驗(yàn)。為了維護(hù)和平，我們必須采取主動(dòng)的措施，判斷什么有效，什么無(wú)效。為此，我們就必須要超越1972年的《反彈道導(dǎo)彈條約》。那個(gè)條約是在不同的歷史時(shí)期針對(duì)不同的敵人而簽署的。”

　　“美國(guó)以及我們的盟友不能受過(guò)去的束縛，我們必須有能力構(gòu)建用以防御2l世紀(jì)的敵人的防御體系，”布什說(shuō)。

　　[4]布什內(nèi)閣的官員聲稱，俄羅斯總統(tǒng)弗拉基米爾·普京10月在華盛頓與布什總統(tǒng)會(huì)談時(shí)曾保證，即使布什退出反導(dǎo)條約，美俄關(guān)系也不會(huì)受到損害。

　　[5]國(guó)務(wù)卿科林·鮑威爾在莫斯科說(shuō)，俄羅斯和美國(guó)就急劇削減遠(yuǎn)程核武庫(kù)基本達(dá)成一致意見(jiàn)，但是兩國(guó)對(duì)美國(guó)的導(dǎo)彈防御系統(tǒng)問(wèn)題存在意見(jiàn)分歧。布什總統(tǒng)的決定就是在這樣的背景下做出的。

　　1.The U.S. decided to withdraw from the nuclear treaty becausethe treaty required itsmembers not__________________.

　　2.When will the U.S. withdraw from the nuclear treaty?

　　3.According to Russia, US' withdrawal from the treaty may bringabout__________________.

　　4.What is Russia's attitude towards U.S. withdrawal from the 1972 ABM Treaty?

　　5.Russian and the U.S. still couldn't reach agreement on_________________.

　　1.[to test missile defense systems]

　　[定位]首段。

　　解析：原文該段中修飾nuclear treaty的定語(yǔ)從句表明了美國(guó)退出核仿控制條約的原因，且原文中的bans...與題目中的require... not同義。要注意的是，require常用require sb.to do/not to do sth.，因此，回答本題時(shí)，要先將原文中的testing改為動(dòng)詞不定式形式to test，故本題答案為to best missile defensesystems。

　　2.[In six months.]

　　[定位]開(kāi)關(guān)兩段。

　　解析：第2段段末的six months' notice before...表明美國(guó)將在6個(gè)月后正式退出條約，故答案為“6個(gè)月后”，注意在將來(lái)時(shí)中表達(dá)“6個(gè)月后”要用介詞in而非after。

　　3.[a nuclear arms race]

　　[定位]第4段首句。

　　解析：原文該句中的trigger與題目中的bring about都有“導(dǎo)致”的意思，由此可見(jiàn)，原文中tigger的賓語(yǔ)anuclear arms為本題答案。

　　4.[Approving/Supportive.]

　　[定位]第8段。

　　解析：原文該段末的...US-Russian relations would not suffer even if Bush pulled out of the treaty表明俄羅斯對(duì)美國(guó)退出ABM條約的態(tài)度是“認(rèn)可的”，這種態(tài)度可以表達(dá)為approving或supportive。

　　5.[a US missile defense]

　　[定位]末段。

　　解析：該段段末的but表明at odds與該段前半個(gè)分句中的agreement表達(dá)的含義相反，可見(jiàn)美俄兩國(guó)在a USmissile defense方面未能達(dá)成一致，故可知答案。
