行走就像游泳、騎自行車和跑步一樣，是一種有氧運動，可以通過給皮膚和肌肉增加供氧而塑造更大的肺活量和耐力。這樣的運動可能是防止心臟和血液循環疾病的一個主要因素。
作爲可能是最不費力氣、最安全的有氧運動，絕大多數人認爲行走可以接受。以舒適的速度行走可以通過激活肺部和心臟增強心肺系統的效率，但比起大多數其他的鍛鍊形式，行走的速度更爲舒緩。
在一項測試中，一組40到57歲的男子每週4天快速行走40分鐘，與同樣年齡每週同期進行3次30分鐘慢跑的男子收到了同樣的改善效果。他們的正常心率和身體脂肪明顯降低。這些變化表明行走可以帶來重要的，甚至是關鍵的益處。
行走也可以燃燒熱量。獲得或失去一磅重量需要消耗3 500卡熱量。因爲以中等速度走一小時的路程將會消耗300到360卡的熱量。每隔一天行走一小時，則每月可以減去一磅半的脂肪，或者說一年可以減去l8 磅脂肪，只要您每日攝入的食物量不變。爲了更快減去體重，每天行走一小時，那麼每月就可以減去3磅脂肪，一年就是36磅。
不管您的年齡有多大，現在都應該花同樣時間考慮身體和養老金或保險。行走是一種關鍵的抵禦疾病和抗衰老的方法。它是自然界給您的一種調整的方式。
答案及解析：
h 【解析】此空前一句意爲“行走就像游泳、騎自行車和跑步是一種有氧運動”，此空所在句意爲“…通過增加給皮膚和肌肉的供氧而塑造更大的肺活量和耐力。”由這兩句可知，此空應填which，which引導定語從旬，修飾“all—aerobic exercise”。
ention 【解析】本句意爲“這樣的運動可能是…心臟和血液循環疾病的一個主要因素。”顯然，此空處應填“防止”。
【解析】由本句中的“the least strenuous，safest…”可知，此空處應填表示程度的最高級，再由acceptable exercise“接受的運動”可知應填most。
【解析】“以舒適的速度行走”用英語說應是“walking at a comfortable speed”，介詞應用at。
【解析】顯然，由本句句意可知此空處應填一個表示“通過”的介詞，應用介詞by。
【解析】由“a more…most other…”可知，此空處顯然應填than，短語more than other表示“比其他…更多的…”。
ing 【解析】由上兩段可知，該短文主要講述步行的好處，此處做試驗，肯定是測試步行。
l 【解析】equal to意爲“等於”，由句意“顯示出…同樣年齡的男人每週在同樣時段進行3次慢跑。”可知，此空必須填“等於”。
ificantly【解析】由本句句意“他們的正常心率和身體脂肪減少…”可知，此空應填一個副詞，修飾decreased，該副詞意思應爲“顯着地，明顯地”。
【解析】由“of the important…benefits”可知，此空應填一個代詞，又由於benefits爲可數名詞複數，故填some。
g 【解析】bring about爲介詞短語，意爲“帶來”。
【解析】本句意爲“步行…燃燒脂肪。”由上幾段可知，這是步行的另一個好處，故此空應填“也”。
【解析】本句意爲“需要3，500卡的能量來獲得或…一磅重量。”顯然，此空應與gain相對。
【解析】本句意爲“因爲以中等速度走1小時的路將會…300至360卡的能量。”顯然，此空應填“燃燒”。“燃燒”英語表達爲“burn up”。
ly 【解析】由a pound-and—a—half monthly可知，18 pounds必定比monthly週期長，而且通過計算可知爲yearly。
【解析】本句意爲“爲了更快…重量，每天走-4‘時…”， 顯然，走路是爲了減輕重量，而不是增加重量。
ever 【解析】由本句句意“…你的年齡，現在都是…”可知，此空應填“無論，不管”。
【解析】由此空前面的“…to give your…”可知，此空也應填give，意爲“花同樣時間考慮身體和養老金或保險。”
nst 【解析】本句意爲“步行是一種關鍵的防禦…疾病和衰老。”顯然，此空處應填“抵抗，抵禦”。
【解析】本句意爲“這是自然界給你的一種調整的…”顯然，此空應填“方式，方法”。
複習題二：
On the President‘s Program
President Arling has put his long awaited economic restructuring program before the Congress. It provides a coordinated program of investment credits， research grants， education reforms， and tax changes designed to make American industry more competitive. This is necessary to reverse the economic slide into unemployment， lack of growth， and trade deficits that have plagued the economy for the past six years.
The most liberal wing of the President‘s party has called for stronger and more direct action. They want an incomes policy to check inflation while federal financing helps rebuild industry behind a wall of protective tariffs.
The Republicans， however， decry even the modest， graduated tax increases in the President‘s program. They want tax cuts and more open market. They say if federal money has to be injected into the economy， let it through defence spending.
Both these alternatives ignore the unique nature of the economic problem before us. It is not simply a matter of markets or financing. The new technology allows vastly increased production for those able to master it. But it also threatens those who fail to adopt it with permanent second-class citizenship in the world economy. If an industry cannot lever itself up to the leading stage of technological advances， then it will not be able to compete effectively. If it cannot do this， no amount of government protectionism or access to foreign markets can keep it profitable for long. Without the profits and experience of technological excellence to reinvest， that industry can only fall still further behind its foreign competitors.
So the crux is the technology and that is where the President‘s program focused. The danger is not that a plan will not be passed， it is that the ideologues of right and left will distort the bill with amendments that will blur its focus on technology. The economic restructuring plan should be passed intact. If we fail to restructure our economy now， we may not get a second chance.

答案詳解
1. C 工藝技術。最後一段第一句“問題的癥結就在於工藝技術，這就是總統計劃的.要點所在。”第四段：“對掌握新技術的人來說，新技術使他們大大增產，而新技術對不能掌握它的人來說，在世界經濟中他們面臨淪爲永久性的二等公民的危險。如果不能做到這一點，那麼任何政府保護主義，進入國際市場都不能有效地競爭。如果不能有技術優勢的利潤和經驗再投資，工業只能進一步落後於國外競爭對手。”這些都說明總統計劃的重點再工藝技術。
A.投資。
D.稅收。只是總統計劃的涉及面。
B.經濟。太籠統了。
2. A 更直接行動。第二段“總統的黨內幾段自由翼要求更強硬、更直接行動。他們要求用收入(稅收)政策來制止通貨膨脹;聯邦財政在關稅保護下，幫助重建工業。”
B.他們需要制止通貨膨脹。C.重建工業。D.保護關稅牆。都只是他們要求中的不分內容，不完整。
3. A 支持。第四、五段集中了評論者的觀點，支持的理由和論點。
B.厭惡。
C.不贊成。
D.調和妥協。
4. D 歪曲。最後一段第二句：“其危險不在於計劃將不被通過，而在於左和右的思想理論家們用修正案來歪曲提案，使計劃要點蒙塵模糊不清，經濟重建計劃應原封不動地通過。”這是作者的態度，也是他所擔心之處。
A.兩黨的反對。
B.兩黨對計劃的不同看法。
C.它的通過。
