英語六級-攻克閱讀關鍵句127.他們擔心的是由于收入分配和經濟安全出現問題

127. What they fear was that the political challenges of sustaining support for global economic integration will be more difficult in the United States because of what has happened to the distribution of income and economic insecurity.

譯文　

他們擔心的是由于收入分配和經濟安全出現問題，美國政府將很難應對為全球經濟一體化提供持續(xù)支持這一政治挑戰(zhàn)。

點睛　

本句的主干結構是“What they fear was＋that引導的賓語從句”。其中what they fear是由what引導的主語從句，作句子的主語；because of...economic insecurity是原因狀語。
sustain的意思是“保持，使……持續(xù)下去”。如：
The clapping was sustained for several minutes. 掌聲持續(xù)了好幾分鐘。
integration的意思是“整合，集成”，global economic integration的意思是“全球經濟一體化”。distribution的意思是“分配”。

考點歸納　

從屬連詞because引導原因狀語從句，有幾點需要注意：
because引導的原因狀語從句常常可以簡化成介詞短語because of。如：
She didn't attend the meeting because she was ill. 因為生病，她沒有去開會。
可以簡化為：She didn't attend the meeting because of her illness.
because可用于強調句結構It is because...that...，并且可以在because前加only或just來加強語氣。如：
It was only because he is the son of the headmaster that he gained the opportunity to participate in the competition. 就因為他是校長的兒子，他獲得了參賽的資格。
not...because結構有時否定從句部分，表示“并非是……的緣故”。如：
The motor did not stop running because the fuel was finished. 摩托車停止運轉，不是因為燃料耗盡。（此句容易誤解成“摩托車沒有停止運轉是因為燃料耗盡了”，這顯然不符合邏輯。）
